Hi Serip

So you have a form containing a TImageEnView and you call

ImageEnView1.IO.LoadFromFile('C:\someimage.jpg');

But the control stays blank?

We are in a similar situation. We downloaded the DirectShow demos for webcam videos and also the components in the trial version. The demo executables worked correctly but when compiling the demo source code with the demo components, TImageEnView does not display the webcam image.

Hi

If our demos work, but when you compile the demos yourself they do not work, it is possible that the lack of a digital signature blocks the functionality. We sign all of our EXE files with an OV code signing certificate from:

I have heard, but cannot reproduce with our setup, that Kapersky anti-virus, and possibly others, block DirectShow functionality with an unsigned EXE:

Thanks for the update. Is that Kapersky?
