Thread: Question about capDlgVideoSource

I am having a problem with the capDlgVideoSource . My problem is that my program only displays 2 of the 3 possible menus in the pop up menu from capDlgVideoSource.

MSDN says:

The capDlgVideoSource macro displays a dialog box in which the user can control the video source. The Video Source dialog box might contain controls that select input sources; alter the hue, contrast, brightness of the image; and modify the video quality before digitizing the images into the frame buffer. You can use this macro or explicitly send the WM_CAP_DLG_VIDEOSOURCE message.

I know that my video source supports all the menus (the one I really need is the one for selecting source, and that is the one that is missing), as I get them all in other applications.

Here is how I call the capDlgVideoSource:

Code:

	capDriverGetCaps(hWndCapWindow, &CapDrvCaps, sizeof (CAPDRIVERCAPS));
	if (CapDrvCaps.fHasDlgVideoSource) 
		capDlgVideoSource(hWndCapWindow);

And here is how I create hWndCapWindow:

Code:

// Create the capture window
hWndCapWindow = capCreateCaptureWindow( TEXT("CaptureWindow"), WS_CHILD| WS_VISIBLE| SS_SIMPLE | WS_EX_LAYERED,
								320,50,	640,480,hWnd, MAINWIN_ID);

 SetLayeredWindowAttributes( hWndCapWindow, NULL, 150,NULL);   

// Now that we have created the capture panel we can connect the first driver
if(capDriverConnect(hWndCapWindow,0) == 0)
	return false;

capPreviewRate(hWndCapWindow,60);  
capPreview(hWndCapWindow,TRUE);

Any ideas?

An other thing that is weird is the my programs fails to connect to a webcam if there is more then one in the machine.

With one webcam connected, this work,
but it returns false if two or more is connected.

Code:

	// Now that we have created the capture panel we can connect the first driver
	if(capDriverConnect(hWndCapWindow,0) == 0)
		return false;

Ok, I found out what the problem was. It by far the most "random" bug I have been so far.

Compiling the program on Windows XP solved the problem( Everything the same, just moved the project folder to a USB pen). The program works under Vista, it just cant be compiled there...

Anyone knows why?
