[RESOLVED] [2008] Webcam Control.

[Tinbeard]

Just a quick question, does anybody know how to invoke and display a web cams settings page from within an application.

I can display and record the video but I am looking to control frame rate and exposure etc.

I've have a couple of 3rd party applications that show my webcams settings page from within the application so I know it can be done I just don't know how

Thanks in advance for any info.

Think I may have found part of the answer but this raises another question, how do I declare this structure in vb.net ?

That is an unmanaged type. You can't create an instance of that type in managed code. You'd need to declare a managed type that corresponded first:

Public Structure CAPDRIVERCAPS
    Public wDeviceIndex As UInteger
    Public fHasOverlay As Boolean
    Public fHasDlgVideoSource As Boolean
    Public fHasDlgVideoFormat As Boolean
    Public fHasDlgVideoDisplay As Boolean
    Public fCaptureInitialized As Boolean
    Public fDriverSuppliesPalettes As Boolean
    Public hVideoIn As IntPtr
    Public hVideoOut As IntPtr
    Public hVideoExtIn As IntPtr
    Public hVideoExtOut As IntPtr
End Structure

Now you can create an instance of your managed type and pass it to any unmanaged functions that require an instance of the corresponding unmanaged type.
