    William,

    The pleasure is all mine.

    Also, good catch! And, you are correct, that you must use USING
    if you specify the argument list when calling a function
    with CALL DWORD. This is so the compiler has a reference to the
    appropriate DECLARE so it will know the types, amounts, etc. of arguments
    that the function uses.

      I have been erading Poffs to try and find an example of a DLL that
      is compiled as a resource - RCDATA DISCARDABLE - and then loaded
      into memory directly with LOADRESOURCE so that its functions
      become available to the program.
      I cant find any. So this is what I have that compiles but gives me
      a GPF at run time.
      GRFXDLL RCDATA DISCARDABLE
      for resource

      GLOBAL hRes AS DWORD, hLib AS DWORD, pAddr AS DWORD

      FUNCTION PBMain AS LONG

      hRes = FINDRESOURCE(BYVAL 0&, "GRFXDLL", BYVAL %RT_RCDATA)
      hLib = LOADRESOURCE(BYVAL 0&, hRes)

      '
      '
      '
      pAddr = GetProcAddress(hLib, "PenColor")
      CALL DWORD pAddr USING PenColor(%HIWHITE)


      pAddr = GetProcAddress(hLib, "BrushColor")
      CALL DWORD pAddr USING BrushColor(%HIBLUE)


      pAddr = GetProcAddress(hLib, "DrawFrom")
      CALL DWORD pAddr USING DrawFrom(50,100)


      pAddr = GetProcAddress(hLib, "DrawRect")
      CALL DWORD pAddr USING DrawRect(200,135)
      any ideas?

        Mike,

        I'm 99% sure that it simply cannot be done, as loading the DLL
        into memory that is most likely very different than the "normal"
        load that Windows does when a program needs to use it.

        My suggestion is that you return to the original plan of extracting
        the DLL and putting it on the HD. That way, you can use LoadLibrary, which
        WOULD be a "normal Windows" loading of the DLL. I realize that
        you're probably pretty frustrated and flustered after trying
        to learn a "new" programming technique. But, the technique is
        actually quite simple and straightforward, and if you can rise
        above the bad emotions, then you can use logic to figure it out.
        The way I learned how to do it, was I found source code from another
        BBS member that showed it. So, I downloaded the code and analyzed it
        until I understood it. Only THEN did I try to implement it myself.
        Maybe a similar strategy will help you?

        Anyway, I am not trying to "preach" to you. Am simply giving
        you some friendly advice as somebody who's been-there-done-that.

        Don't give up!

          Clay,
          Thx, but no frustration here these forays into the unknown are
          allways "interesting". I cant help thinking there must be a way
          to load the DLL from resource into memory and get at the
          functions. Its just a case of finding the address right.

          But if all else fails then yes i can just drop it to the HD and load
          it from there ...

            Oh, Mike, I think I noticed in your 2nd-to-last posting that your
            line in your RC file is incomplete. The way it should be:

            1 RCDATA DISCARDABLE "dllname.dll"

            The first item can be either a numeric or name identifier. It is
            the resource IDENTIFIER, NOT the actual name of the resource!
            However, it CAN be the actual name of the resource, it's just
            that that position is for the IDENTIFIER.
            It is the last param, the one in quotes, that is the actual
            name of the resource. The way I spelled it out assumes that
            the resource file is in the current folder; if need be, you
            can prepend the full path to the resource.

            OK, as soon as I submit this, I'll go back and reread your posting,
            to make sure I hadn't simply read it too quickly.

              Going back to Mike's original question...

              > I need to ship a single EXE, but that EXE
              > requires a Dll (GRFXtools.Dll)

              You have two basic choices:

              1) Jump through hoops -- big hoops! -- and try to embed the DLL in your EXE. Or...

              2) Use a Windows SETUP.EXE program. A setup program can contain as many files as you need (EXE, DLL, data, Help files, license files, README files, etc.) and it can handle details like the creation of a directory, the creation of Start menu, desktop and quick-launch icons/shortcuts, the addition of an Uninstall item in the Control Panel's "Add/Remove Programs" applet, and many other useful things.

              IMO, trying to create a monolithic EXE that can be run from any directory is a hold-over from the days of DOS. In the Windows world it seems old-fashioned and, frankly, amateurish. (I'm not trying to be insulting, but that's the only word I can think of at this early hour. My point is that 99.9% of all professional Windows apps are installed by a SETUP.EXE program.)

              Providing a SETUP.EXE file is very easy if you use a tool line INNO Setup (which is free) and it provides exactly what you asked for: a single EXE that you can ship to your users. The only difference is that the first time they run your program it will install itself cleanly and professionally on their system.

              And in many cases the SETUP.EXE will be smaller than the EXE and DLL added together, because most setup programs use zip-like compression.

              DLLs were not intended (by Microsoft) to be embedded in an EXE. People have found ways to do it, but why do it when the alternative is so attractive?

              > Whats the common method for doing this

              By a HUGE margin, the most common method is using a SETUP.EXE program.

                Well,

                While I see an advantage at times in have a single exe for tools and what not, I prefer that large programs are modularised and I use INNO setup like Eric. It also means that if you vendor (ie sql tools) releases a patched DLL to fix something for you then you can update just that DLL and not the whole program which is likely to get large if you are packing all your DLLs and reasources into it.

                Seems like you are not achieving much extra with a single exe and may be paying in performance and opening yourself to more potential for bugs.

                But like I say, it depends on what you are doing, somethings are better off small and simple

                  Paul,

                  My setup EXE already contained the capability for the user to select
                  WHICH support files he wanted/needed to install. The setup EXE
                  never had to be modified to adjust for different/new/deleted
                  supported files embedded after I initially wrote its code. It was
                  all automated. If you're interested in the technique, I can reduplicate
                  the code and e-mail it to you, just so you can see the method it used.
                  However, the duplication would be different than the original, as I no
                  longer have the orginal source files. I dumped them for the sole reason
                  that I completely deleted my website, and no longer needed them.

                    Folks, there are advantages to the user (<U>your</U> customer) for supplying a SETUP.EXE even if your actual app is just one EXE file...
                    • The end user can easily choose where it should be installed
                    • It's easier then explaining to technically-challenged users how to create a separate folder or where is the best place to install the app
                    • The user can be presented with a license agreement that they have to agree to before the install proceeds
                    • You can easily create desktop shortcuts to the installed EXE
                    • You can easily generate a log file of the install to assist in tech support problems
                    • The SETUP can add registry entries and even register COM components seamlessly
                    • Latter versions of Windows "track" the usage rate (although the "usage scale" is not very granular)
                    • The user gets an Uninstall listing in the "Add/Remove Programs" dialog

                    And there are probably other significant advantages too...

                      Clay --

                      [Hmmm... In the time it took me to compose this Clay edited his message and changed everything I responded to. No sense playing Dueling Edits, so I'll just post what I wrote.]

                      First off, I'm not offended in any way. Different strokes for different folks!

                      > Because of its need to be generic enough

                      That's an incorrect assumption about INNO. All you need to update is a plain-text script file which tells INNO what you want it to do. A tool is available for building the initial file and from then on, making changes is a snap. (In most cases I simply update my program's files and click "Build" without changing the script.)

                      > I find it very hard to believe that something
                      > like INNO can do very many things that I could

                      Of course you can write your own SETUP.EXE! But I didn't think that's what we were talking about. I was expounding on the benefits of using a SETUP.EXE instead of trying to bundle a DLL with an application's main EXE. The benefits I mentioned would apply to ANY setup program, I just used INNO as an example. Mike wants to be able to send his users a monolithic EXE which is the actual program, not a setup program.

                      > And, personally, I am TIRED of the many dialogs
                      > you have to go through to simply install software
                      > that uses something like INNO.

                      INNO allows you to specify which dialogs are displayed. Nearly all of them are optional. Maybe all... I have never tried to strip one down that much.

                      > I don't have any concrete evidence, but I find it
                      > hard to believe that MOST end users even CARE WHAT

                      > what folder in the Program Files folder the software
                      > uses.

                      I (for one) appreciate the opportunity to choose the drive, at least. But with INNO you don't have to ask them if you don't want to.

                      > I find very little USE for the dialog that asks,
                      > "The specified folder does not exist.

                      That too is optional with INNO. You're making a lot of assumptions about a program you haven't used.

                      I agree 100%. But I'm not sure that doing something in a nonstandard way is necessarily virtuous either. In the case of something "routine" like an installation program, I appreciate it when a program uses a standard system. And if the first impression a new user has is "Ok, I know how to do this" that's generally a good thing. (Imagine what Windows would be like if every program "did its own thing". It would be like... Linux. {GD&R})

                      > I personally use the DEFxxx verbs instead of
                      > explicitly declaring my variables. I never, ever
                      > use "#DIM ALL".

                      Don't get me started!

                      > YOU may believe that they are OBJECTIVE, simply

                      I'm not sure why you think I believe that. I do have strong opinions about certain things, and I do tend to tell people what I think, but I don't think I have a habit of claiming to be "absolutely right". At least I hope not!

                      In this case I was saying that I think a SETUP.EXE-style program is a better solution than a main EXE with an embedded DLL, that's all.

                          Eric,

                          You have completely humbled me, in a GOOD way. Because of what
                          your last reply, and Paul's, and Lance's, said, I think that *I* will
                          start using INNO. You are completely correct, and RIGHT, that I
                          made false assumptions on software that I never even took for a test drive.

                          I will move to INNO, if for no other reason, than what you said
                          about it only requiring one script file. That would be ENORMOUSLY
                          easier than having to rewrite the setup EXE, and the supporting
                          files, etc., that I was previously using, from scratch. I am putting
                          up a website and starting to distribute my public softwares again,
                          after a 6 month hiatus.

                          So, do you have a URL where I can go to download the INNO package?
                          I already have my website (with Tripod <YUCK!!!> ), and as soon as
                          I create the HTML's, I will start using INNO to package my public softwares
                          and start uploading them.

                          Thanks again, Eric. Your gentlemanly ways do you credit.

                              Michael,

                              Thanks for the hyperlink!

                              However, your sample script was pretty much "greek" to me.
                              I guess I'll have to do some indepth reading of the INNO
                              documentation, then use it for test runs, until I understand it.

                              Just reread your sample script. It now makes a lot more sense
                              to me than the first review did.

                                Check out ScriptMaker too... although it is no longer being developed, it adds a wizard-like GUI for creating and editing scripts. I'm not sure if it is still compatible with the latest Inno buils though... I've not updated for some time now as I have a combination of INNO [Extensions] and ScriptMaker that works well for me.

                                  Well Mike, I warned you that attaching the Dll as a resource
                                  would raise some posts

                                  For a simple one EXE program, where I may need the DLL, I've
                                  found this to work just fine with no issues on the unload and
                                  no need for a setup.exe. Other programs may well need them and
                                  of course then you should have one you like and use it.



                                  ------------------

                                    OK guys, I guess I'll have to explain a little more here since you are all jumping to
                                    HUGE conclusions incorrectly. The first thing I should mention is that I am
                                    shipping an INCOMPLETE app on a regular basis. Right now I am
                                    developing a SMALL app for a client (122k without splash screens
                                    and icons, 500k with) If I include the GrfxTools Dll and then
                                    compress the EXE using UPX, the grand total is 324k!

                                    Now you might say well thats alot of hassle, including the DLL as
                                    a resource, and compressing the whole thing, you might as well
                                    use INNO.

                                    Well, I wrote a wrapper, (available shortly as plug in for Jellyfish) based
                                    on an original idea by semen (thankyou semen) that handles this
                                    in two lines:
                                    'xResource GRFXDLL RCDATA DISCARDABLE Includes/GfxT_Std.DLL
                                    'xCompress
                                    EVERY time I hit the compile btn the resource is made and the
                                    resulting EXE compressed. I turn it off when developing but as
                                    you see its so simple to engage

                                    So now I have a very small app. And BTW most of my EXE/DLLs are
                                    small. My clients are usually NOT that technically savvy and require
                                    really simple obvious steps.

                                    I recently made an demo app that I sent to a bunch of clients as
                                    a demonstation of what could be done with Fibonacci analysis.
                                    It had a run time DLL in keeping with the logic we programmers
                                    accept as making sense.

                                    I did not use an installer because people are terrified of them. In the
                                    financial arena, a computer has a very different significance. If you
                                    earn a living with that machine it is treated very differently than your
                                    home computer. Some clients have both, but most use one and are VERY
                                    wary of installing anything in case it messes with the settings of something
                                    that is currently working. Just the visual of an installer taking over the whole
                                    screen is a bad idea in the first place (i forget if INNO does this).
                                    As you know the instant messenger apps are incidious. You cant shut em
                                    down, they plaster themselves everywhere and throw things in your face, is
                                    it any wonder people are gunshy. Nortom tools with its incessant reminders
                                    any app with the registration nag screens or what ever.

                                    It is a rare app that does JUST what it advertises
                                    and nothing more, so the assumtion is my apps installer will too. They dont
                                    have the time to go thru and find all the folders and shortcuts and launch items
                                    and remove them all. The UNINSTALL for the most part on most apps
                                    does not remove everything. People know this. they generally dont like
                                    installers unless it is from a very reputable source.

                                    So i zipped up both the EXE and the DLL and sent the Zip. Well you
                                    would be surprised how many people had problems with the ZIP archive
                                    when attached to an email. So i put the zip up on a website for download.
                                    There were still problems, fewer, but still problems with unzipping!
                                    Finally i put a link to the EXE and the DLL so they could d/l both.

                                    Well that was too hard for some of them. "whats a DLL", "Do I need it"
                                    "isnt that system stuff? wont it mess up my system" "your app doesnt run,
                                    should I try the DLL" I put the DLL in the MY DOCUMENTS folder,
                                    but the app still wont run" etc etc

                                    As you can imagine this wastes alot of my time in responding to these
                                    kinds of problems. The solution, for me anyway, is to just ship one file:
                                    MyAPP.EXE. No installers, no required DLLs, No zip files, just the APP.

                                    THIS WORKS 100% of the time
                                    At 324k size is really not an issue

                                    The next assumption you guys have made is that I have a finished APP.
                                    I do not I am developing an APP. At each major stage I send a copy
                                    to the client for review and feedback. Sometimes this is once a day. At
                                    the end of a 16hr day coding the last thing i want to do is switch gears
                                    and get my head into INNO to produce an installer. One option screen
                                    from INNO is one two many at that point I want to simply attach it and
                                    send it. over and over and over. Thats alot of time saved

                                    Also, I am sure my client does not want to run an installer every day to get
                                    the latest version. Im sure he has a folder all set up ready to drop it into. Its
                                    just so fast and hassle free. Download, double click, done!

                                    If I do upgrade to GrfxT_Pro.DLL then it is seamless to the client as it is
                                    included with the app and he will never know. There will never be any
                                    confusion about two Dlls in the folder and which one do i need etc etc.

                                    I am not in the business of educating clients as to waht is professional
                                    software approaces or not. I am in the business of providing solutions
                                    to financial problems. I dont care if it is not considered correct etiquete,
                                    I want my clients to run my app, they want to run my app. whatever it
                                    takes to accomplish that is fine with me

                                    I did not create the environment that I develop in, I am simply
                                    responding to it. This is my solution to an imperfect situation that
                                    works, guaranteed, 100% of the time. If anyone else has a better idea
                                    that does not require an installer and ships a single app that will run
                                    upon launch, lets hear it.

                                    As Paul put it so well:
                                    > somethings are better off small and simple
                                    I am just in a different environment. I had one client that has traded
                                    with DOS for 15 years. He wanted to convert it to windows. He
                                    has stuck with DOS because it works. He makes money with it. He is
                                    terrified of windows. He bought a new machine and when I had him
                                    on the phone it became apparent that he did not understand how to
                                    resize a window! It took me 2 hrs to get him to zip up his dos app
                                    and send it to me. He is prime example of it aint broke, dont fix it.
                                    He probably is a good candidate for an installer, but my point is
                                    sucessfull people in this field are often not at all technically savvy.

                                    I get the definate impression the Perfect Sync dont want me to do this
                                    for some reason, and I may end up not doing it if it really is alot of code
                                    to load an embedded DLL and get a pointer to a function within that
                                    DLL, but I wanted to explore it, get it to work and then decide -
                                    (with your permission of course Eric)

                                    So could someone give me an example of loading a DLL from resource
                                    into memory, and then getting a pointer to the functions now ... please...


                                    PS. How hard is it to get word wrap to work on this board?

                                      Nope, that's an incorrect impression.

                                      You don't need my permission. You may distribute the Graphics Tools DLL according to the terms of the License Agreement which applies to the version of the product for which you have a valid license.

                                      We don't care whether you distribute the DLL directly, or put it in a SETUP.EXE program, or embed it in your EXE, or anything else, as long as you do it within the terms of the License Agreement. (I am being purposely vague because our licenses provide different rights for different products and versions. See http://www.perfectsync.com/SoftwareLicenseAgreement.htm for specific information.)

                                      But as Paul explained when you contacted [email protected] about this technique, we can't help you. We have never embedded a DLL in an EXE here, and we don't encourage people to do it -- meaning that we don't go around saying "Hey, try this!" -- so you're on your own. If anything, we have been trying to encourage you to use a technique that we could help you with. Nothing more and nothing less.

                                      Ok, I was also trying to encourage you to use a common, standard technique instead of an unusual one. But that was just a friendly suggestion from me personally, not "official" advice from Perfect Sync. I would have given you the same advice even if the DLL wasn't one of my company's products.

                                        [If anyone else has a better idea
                                        that does not require an installer and ships a single app that will run
                                        upon launch, lets hear it.]

                                        Again, I think you might ask Don Dickinson more of his C-Selx. It can be set to compile all
                                        dependent files into one exe and when it is started, it will expand all files, run the
                                        main program. It can also be instructed to delete all the dependent dlls and other files
                                        when the main program ends, so there is nothing left in the directory, apart from the
                                        original C-Self exe.

                                        It can also be set to not run after a termination date.

                                        I have tested these features and found it quite satisfactory, however, I am not a distributor
                                        of commercial software. I develop In-House applications.

                                        Regards,

                                        David

                                          You could pack both files into a one-file installation and give it
                                          similar name as the program. When user first time starts it as
                                          instructed, it unpacks the files silently, after which it starts
                                          the real program before exit. To wipe out all traces, real prog
                                          can look for installer at first run and delete it if there.

                                          Don't know if INNO can do this, but maybe you have access to more
                                          advance installer that can. I use Wise myself and there have used
                                          it's recursive search feature in upgrade package, so users can start
                                          it from anywhere, and it automatically searches/finds prog to update.
                                          Have had 0 calls for help with that one.

                                          Have unfortunately no answer to real question, about embedding a DLL,
                                          but the above way should be just as support free, or probably even
                                          more support free.

                                          Whish I had more time to play - question still is interesting and can't
                                          be impossible to solve. Probably even exist easy solution - but hard part,
                                          as always, is to find out that easy answer..
