	Quick Info

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.

BOOL capDlgVideoSource(

hwnd
);

Parameters
hwnd

Handle of a capture window.

Return Values
Returns TRUE if successful or FALSE otherwise.

Remarks
The Video Source dialog box is unique for each capture driver. Some capture drivers might not support a Video Source dialog box. Applications can determine if the capture driver supports this message by checking the fHasDlgVideoSource member of the CAPDRIVERCAPS structure.
