I think you need to copy bitmap bits to memory mapped file.<br />
Why do you need to work with Webcam using Delphi program? It's only few lines of code to do this in MFC. MFC doesn't have special support for this, but Video Capture functions are very high-level and easy to use.

Can you provide some sample source codes?<br />
<br />
Thanks.

Thanks.

If it is okay with you, can you send it to audio74@yahoo.com.<br />
Also, do you have sample source code for the memory mapped files?<br />

Hi,<br />
&nbsp; &nbsp;I have a delphi program that grabs video frames from a web cam. It obtains a TBitMap Object 15 times a second.<br />
<br />
I need to write another MFC program running in parallel that displays this TBitmap.<br />
<br />
How can the MFC program get the TBitmap from the Delphi program? What is the best way to do this? Is is possible to do this without copying the TBitmap to some shared memory?<br />
<br />
Thanks.<br />
