could DShowLib::Grabber donnt do display work, render data to an null render ?

[addwaer]

i wonder whether could connect a null render after DShowLib::Grabber , for i just wanna
grabber the image data, and donnt want to display immediately .
i test some sample code , if i m_Grabber.setHWND( NULL ) , or even donnt call m_Grabber.setHWND()
it also do display work in a Active MovieWindow.

i have used directshow build a normal filter graph as below
Capture Fileter(DFK 72BUC02)--------->Sample Grabber ----->Null Render
it works well , but cannot do some some setting work, eg: enable external trigger.

btw: where could download IC Imaging Control C++ Class Library for vc6 , for all our develop
platform is vc6.

thanks!

Hello addwear,

simply call Grabber::startLive() with parameter false: Grabber::startLive(false)
