Webcam / Video Capture - Dialogless Camera Select?

[wpearsall]

hi guys...

im using the AVICap code to open up a view of a webcam - then setting the parent "window" of the image to on my form - so it appears my application owns the image etc...

Microsoft WDM Image Capture (Win32) < the "Driver" being used to capture the image...

Starting video like this....

Dim lpszName As String * 100
    Dim lpszVer As String * 100
    Dim Caps As CAPDRIVERCAPS
 
    '//Create Capture Window
    capGetDriverDescriptionA 0, lpszName, 100, lpszVer, 100  '// Retrieves driver info
    
    lwndC = capCreateCaptureWindowA(lpszName, WS_CHILD Or WS_VISIBLE, 0, 0, 160, 120, lgOwner, 0)
 
    '// Connect the capture window to the driver
    capDriverConnect lwndC, 0
    
    '// Get the capabilities of the capture driver
    capDriverGetCaps lwndC, VarPtr(Caps), Len(Caps)
    
    '// Set the video stream callback function
    capSetCallbackOnVideoStream lwndC, AddressOf MyVideoStreamCallback
    capSetCallbackOnFrame lwndC, AddressOf MyFrameCallback
    
    '// Set the preview rate in milliseconds
    capPreviewRate lwndC, 66
    
    '// Start previewing the image from the camera
    capPreview lwndC, True
        
    '// Resize the capture window to show the whole image
    ResizeCaptureWindow lwndC
    
    ' say we are viewing the video
    bViewVideo = True

and disabling the video like this:

'// Disable all callbacks
    capSetCallbackOnStatus lwndC, vbNull
    capSetCallbackOnYield lwndC, vbNull
    capSetCallbackOnFrame lwndC, vbNull
    capSetCallbackOnVideoStream lwndC, vbNull
    capSetCallbackOnWaveStream lwndC, vbNull
    capSetCallbackOnCapControl lwndC, vbNull
    capSetCallbackOnError lwndC, vbNull
    
    DoEvents
    
    bViewVideo = False

all working great... EXCEPT:

am i correct in thinking i also need to DESTROY the window that was created using this code...

lwndC = capCreateCaptureWindowA(lpszName, WS_CHILD Or WS_VISIBLE, 0, 0, 160, 120, lgOwner, 0)

just got wondering this, since the last visible image from the camera remains on my form, even though the window should of closed? (not a problem, since i hide this control anyway, but would be nice to keep the resources free)


and secondly.. i have two cameras that i can select... - i dont suppose there is a dialogless way to select either camera is there

i have searched the forums and have come to the conclusing the dialog is required, but would be nice just for confirmation of this. Cheers.
