DLLs and Vista? / 64 bit? / ...?

[Michael Mattias]

Eric, you and your users can look at what I do re 'multiple use' DLLs and #INCLUDE files...

I have one folder which contains all my 'multiple use' DLLs and that folder is on my PATH.

That's especially handy when one of the DLL vendors (eg Perfect Sync were I a user) sends out a new release. You can test the new release by putting the new files directly in your 'development folder' (where the exe is located) and the program will use that, because that folder is earlier in the "hunt" sequence used by LoadLibrary().

Only when you are sure the new DLLs are 'solid' do you copy them to your current "DLLs" folder.

I also suggest you keep a log... here's mine..

_index.txt for C:\Utility\Dlls

4/08/03 Created folder and added to path
09/03/07 rearranged to put all entries for same file together like product version logs. 
02/26/08 Added entry for LIBHARU. Note that this file does not have a version resource 
         and you have to select by size. LIBHARU 2.0.8 size = 768K

             fileversion="1.9e(1)"
   3.29.06  Overwrote ddoc.exe 1.9.5e1 with 1.9.5e2  (wider bookmark control)

For finished applications, you can look at at AppPath settings in the registry to eliminate multiple installs of the same third-party DLLs.

#INCLUDEs is a little more work, in that you have to create a common folder for your third party tools, and then modify your IDE's #INCLUDE path to use it. BUt the same principle applies: you can easily test new versions of header files by putting with your *.bas source, only updating your master #INCLUDE file folder when you know the new file is good.

(Idea courtesy Big Blue.. $PROCLIB directive in JCL.. multiple libs are searched IN ORDER so you can keep old versions in place until you know the new version is good )

PS: Not sure where that DLL is loading from?
Use this:
Show Loaded modules and path from which loaded June 12 2003
Show Loaded Modules Source and Executable package for PB and VB
Visual Basic include files/demo code by Balthasar Indermuehle. (PB code by YT.)

I am told this can be especially handy for VB users, who often have no clue from where VB is loading something

> Are these shared dll's?

Yes, they are "library" DLLs that can be used by many different programs.

> i assume no change for that?

Correct.

> which dumbo is placing dll's in the Windows folder nowadays?

I guess you can call me Dumbo, Edwin.

Perfect Sync's customers often use SQL Tools, Graphics Tools, etc. to create more than one PowerBASIC application.

If they distribute an app to their customers we do recommend that they place the DLL in their EXE's folder, but (especially) on a development machine we usually recommend System32.

Are these shared dll's?
We put our dll's cin the app folder, i assume no change for that?
which dumbo is placing dll's in the Windows folder nowadays?

[Brice Manuel]

Oh... well... um... that makes a lot of sense, doesn't it?

Well, we are talking about Microsoft

I was hoping to avoid Vista completely.

IMHO (others may disagree), you could skip Vista and go with 7. The special "rules" should be the same. Any "gotcha" on Vista should also cause a "gotcha" on 7 and the solution should be the same.

> Only 64 bit DLLs can be in the system32 directory.

Oh... well... um... that makes a lot of sense, doesn't it?

Thanks much! I'll pass that advice along to the customer.

It's time to order a new computer and OS for testing, I guess. Darn, I was hoping to avoid Vista completely.

You are putting the DLL in the wrong directory for a 64 bit OS.

Only 64 bit DLLs can be in the system32 directory.

32 bit DLLs must be placed in C:\Windows\SysWOW64

[edit]
You need to remember that your app is running under emulation on a 64 bit OS, and the emulation layer redirects to 32 bit locations. Newer installers can check for a 32 bit or 64 bit OS and let you install files where they should be.

I recently received an email from a Graphics Tools licensee who is reporting a problem when using the 64-bit version of Vista. (I don't know whether or not that is the basis of the problem, but it's a starting point.)

If they place the Graphics Tools DLL in the same folder as their EXE, everything works fine.

If they place the Graphics Tools DLL in the C:\Windows\System32 folder the app fails.

I had them check the PATH and C:\Windows\System32 is included.

Has there been a recent (Vista? 64-bit?) Windows rule-change that I don't know about?

Is this likely to be a permissions/security issue, or...?
