Doesn't the MSDN sample ACMapp display how to do this???

I have found it in winbase.h #define INVALID_SET_FILE_POINTER ((DWORD)-1) but only in sdk downloaded from Microsoft. This define does not exist (on my computer) in both VC6.0 and VC7.0 include/src folders. Mukkie

Are they sent to my email or what? cause my email address is runes@hotpop.com

What is the debugger telling you in detail about the execption? (Exception type like "Microsoft C++ exception" or "Access violation" or something like that.) 2) If you choose Cancel to debug your app, where exactly the program is halted? This is the point in code which throws the exception. 3) If the above does not give you any helpful information, it might also be a worthwhile option to single-step your code in the debugger to see where exactly the exception occurs. -- Daniel Lohmann http://www.losoft.de (Hey, this page is worth looking!

Try to initialize your WAVEFORMATEX struct with this function: void InitFormat(LPWAVEFORMATEX pwfx, WORD wChannel, DWORD dwSamplesPerSec, WORD wBitsPerSample) { _ASSERTE( NULL != pwfx ); pwfx->cbSize = sizeof(WAVEFORMATEX); pwfx->wFormatTag = WAVE_FORMAT_PCM; pwfx->nChannels = wChannel; pwfx->nSamplesPerSec = dwSamplesPerSec; pwfx->nAvgBytesPerSec = dwSamplesPerSec * wChannel * (wBitsPerSample>>3); pwfx->wBitsPerSample = wBitsPerSample; pwfx->nBlockAlign = wChannel * (wBitsPerSample>>3); } VOTD:"5 I know that the Lord is great, that our Lord is greater than all gods. 6 The Lord does whatever pleases him, in the heavens and on the earth, in the seas and all their depths."- Psalm 135:5-6

redeemer wrote: the reason i changed it was that it wouldn't compile when i used ACMDRIVERENUMCB, a lot of compile errors showed. so i asked what could be wrong and one said that maby ACMDRIVERENUMCB was just a typedef of WINAPI so i used that, could that be where the problem lies? I doubt it. (Maybe this is just because it was me who suggested you to change it ;P. However, I never said is a typdef for WINAPI, but it is a typedef for the pointer to listCallback. Take a look at the definition of ACMDRIVERENUMCB in the header file. The docs are just wrong here.) However, back to your problem: It works if you remove all code from your listCallback. Therefore it is probable (but not sure...) that the problem is caused by that code. (The exception messages you get are no problem. If the debugger does not claim about an unhandled exception they are catched inside MSACM32.DLL - nothing you should worry about.) Next step: Trackle it down. If it fails because of that code, check which part of the code (especially the calls to acmDriverDetails() and/or SendMessage()) causes the problem. (Don't forget to pass a valid string in SendMessage() if you remove the call to acmDriverDetails()!) -- Daniel Lohmann http://www.losoft.de (Hey, this page is worth looking!

Hm... - Did you placed a breakpoint on the very first statement of your listCallback? - The cast to ACMDRIVERENUMCB for the first parameter to acmDriverEnum() should not be necessary. If the compiler complains about it, there is something wrong. -- Daniel Lohmann http://www.losoft.de (Hey, this page is worth looking! You can find some free and handy NT tools there :-D )

Thankyou! Solved it all!

The dialog shows O.K. for me. The only diference was I tested it with hwndOwner set to NULL. Is the owner window (ghWnd) valid and displayed window? Sonork 100.15206;PavelK

are you including "windows.h" before including commdlg.h ? -c To explain Donald Knuth's relevance to computing is like explaining Paul's relevance to the Catholic Church. He isn't God, he isn't the Son of God, but he was sent by God to explain God to the masses.    /. #3848917 image effects!

Thanks, it was the lpstrInitialDir.

Copy the .dsp and .dsw to another place. Rename them. Open them in a text editor (such as MSVC itself - but open them as text!). Replace appropriate sections. Some might say "Why in the name of ... is this so complicated". It's not, it's the way of Microsoft: Whenever you can make something undocumented: Make it so!

according to this, you need to test RC_BITBLT -c Garbage collection, making life better - for weenies! Image Processing - just like mom used to make.

a palette is what you use to define the colors for a colormapped image (1,4 or 8 bits per pixel). if you're writing a 24 or 32 bpp BMP/DIB, you don't need a palette. in a BMP/DIB, the palette is the set of (up to) 256 RGBQUADs after the BITMAPINFOHEADER. after that comes the image data, formatted in any of a dozen or more ways, depending on bit depth, compression , JPG , PNG, etc.. -c Garbage collection, making life better - for weenies! Image Processing - just like mom used to make.

bmiColors is the palette, not the image. -c Garbage collection, making life better - for weenies! Image Processing - just like mom used to make.

MSDN : The RGBQUAD structure describes a color consisting of relative intensities of red, green, and blue. typedef struct tagRGBQUAD { // rgbq BYTE rgbBlue; BYTE rgbGreen; BYTE rgbRed; BYTE rgbReserved; } RGBQUAD; Members rgbBlue Specifies the intensity of blue in the color. rgbGreen Specifies the intensity of green in the color. rgbRed Specifies the intensity of red in the color. rgbReserved Reserved; must be zero. Remarks The bmiColors member of the BITMAPINFO structure consists of an array of RGBQUAD structures. And keep in mind that an array is a pointer! u can always write: int a[5]; a[1] = 2; *(a+1) = 3; // Means a[1] = 3; Papa Murex Co.

If you have a BITMAPINFO structure, then you can write it out to disk, using IOStreams or Microsoft specific methods. GDI+ will do this for you, for bmp/jpg/gif/I forget the others.
