If I were you I will determine the value and assign it to a constant. Otherwise, you will have to use a macro.

Code:

#define CTL_CODE( DeviceType, Function, Method, Access ) (                 \
    ((DeviceType) << 16) | ((Access) << 14) | ((Function) << 2) | (Method) \
)

Which - if I was careful here - can be made into FUNCTION with...

Code:

FUNCTION CTL_CODE (iDeviceType AS DWORD, iFunction AS DWORD, iMethod AS DWORD, iAccessAS DWORD) AS DWORD

 LOCAL    W AS DWORD, Z AS DWORD

 Z = %NULL

 W = iDeviceType
 SHIFT LEFT W 16
 Z = (Z OR W)

 w = iFunction
 SHIFT LEFT ACcess, 14 
 Z = (Z OR W) 

 w = iMethod
 SHIFT LEFT W, 2
 Z = (Z OR W)

 Z = (Z OR iMethod)

 FUNCTION = Z

END FUNCTION

Then again, I *do* need that vacation....

Cliff Nichols · 14 Mar 2008, 03:11 PM

Thanx guys,

You guys are life-savers. I was locating the missing header files that I did not have access to. (Apparently hidden in the DDK, and all I have is DDK documentation, but no sample to work from).

I'll give the code a shot, and see if I can use it to move over my hurdle with USB.

MCM...Have fun on Vacation

Pierre...Thanx again for all your help on my "What used to be LITTLE Project"

Michael Mattias · 14 Mar 2008, 03:44 PM

I was locating the missing header files that I did not have access to.

I got a complete set at the Borland web site. They made some older version of their "C" compiler available free for the asking (I think you had to leave your name), and it included a directory with all "*.h" files.

The C compiler itself I could not care less about, but having the entire set of Windows header files has been invaluable. Add Bob Scott's disk utility (here somewhere) [or anything which will search a filespec for a token] and you can find all the stuff ever mentioned in the WinAPI SDK documentation.

No, I don't know if that offer is still available from Borland, but when you check (as I know you will), you can let everyone know.

Michael Mattias · 14 Mar 2008, 03:56 PM

And if you do get a bunch of "*.h" files and want to quickly convert to PB syntax, here's a Golden Oldie....

Win 32: Use REGEXPR to convert ".h" and .".rc" files into PB ".bi" files with equates March 05, 2000

.. and a "newer" version...

Cliff Nichols · 14 Mar 2008, 04:07 PM

Thanks again MCM

When 1st porting C header files, I had found Kev Peel's converter in the Downloads section. I was just about to add the macro code (which was where his code could not translate correctly) when I noticed, it is only the *.exe and not source code to be adapted

So hopefully Kev Peel is watching? Or MCM's code will lead me to a equiv solution.

Anyways, with a bit of tweaking, I believe I will soon have an *.inc file ready for posting.

A few questions

Piecing together both Pierre's and MCM's help, and maybe my running through docs one too many times

I have a few questions, since my "Grey-Matter" is starting to liquefy into a pile of "Jell-o"

Hi Cliff,
Quote: - Where is this declared ?

Becose we are dealing with C code files,
some important keyword could be used to search
on the net. C use ".h" files and "#define" syntax declaration.
Using the right keywords is the harder part, then Google will do the rest.

So, to find "FILE_DEVICE_USB",
Googling <<.h #define FILE_DEVICE_USB>>
give often good results.

From there you will find
"#define FILE_DEVICE_USB FILE_DEVICE_UNKNOWN"
Now you have to find FILE_DEVICE_UNKNOWN using the same process.

- About CTL_CODE() function, as you already found,
it's in fact only a way to put many info's in a single DWORD
called a "system I/O control code".
Bit 0 to 1 for the method transfer type
Bit 2 to 13 for the function (Bit 13 is Custom)
Bit 14 to 15 for access
Bit 16 to 31 for the device type (Bit 31 is Common)
See http://msdn2.microsoft.com/en-us/library/ms795909.aspx

A good way to Google it is <<CTL_CODE MSDN>>,
It will search MSDN much better than MSDN itself.
You should find that it is declared in windev.h,
from there one must convert from C to BASIC
or use, already done, Erwin van de Wiel function in POFFS.

Bottom line, choosing rights keywords is crucial and often difficult.

Cliff Nichols · 16 Mar 2008, 07:47 PM

Bottom line, choosing rights keywords is crucial and often difficult.

So true, so TRUE....Often I try to start as generic as I can because of programming language differences....so I am a bit guilty of not google-ing a phrase without #define before whatever it is that I am trying to look up.

Once I have a sample, then its a matter of hoping that the sample being worked from correctly declared. (In some cases may be DWORD, when its really a LONG, or Vice-Versa)

I know I have a lot to learn yet, and docs can be REALLY confusing sometimes. But at least I keep trying

(Ain't I a glutton for punishment?
