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
Handle of a capture window.
Returns TRUE if successful or FALSE otherwise.
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
