How capture video fotograms in VB 6.0

Hi to all:

I have a big problem and I write to ask for help. Sorry if this message does
not arrive to the apropriate group. I have selected them paying attention
but I am not sure to do it well.

I want to capture a fotogram of a media player control in VB6 and I capture
the screen as in the section "Visual Basic 4.0 16/32 Capture Routines" of
this
URL:

http://support.microsoft.com/default...microsoft.com:
80/support/kb/articles/Q161/2/99.asp&NoWebCon tent=1

This program takes with the DLL a picture of all the screen and after
selects the interestig zone.

My problem is that this code captures fine all the PC screen but not the
video reproduction screen of Media Player that apears black. I think that
this is because DirectX rites directly in the video controler and it does
not memory maping but I am not sure.

Someone can tell me how capture the fotograms? Please!!!!!!!!! !!
It will be fine too if someone talks me about another control that enables
the capture. They must exist because there are video reproduction programs
that enables the capture but not the WMP.

You can answer me in english, french or spanish. I can read the three. I
will read the news but if you want you can write to
berruetaNO(at)S PAMiutbayonne.u niv-pau.fr without NO SPAM.

Thanks. You will really be very helpfull.

Hi, Im trying to develop a Visual C# .NET app. that uses DirectShow filters to capture video from camera source. However, after going through a series of articles, I've seen that DirectShow is not directly supported in Visual C#.NET. Im wondering if there's any way to use the video-capture filters of DirectShow in Visual C#. Otherwise, would it be possible to create a Visual C++ DLL that uses DirectShow filters to capture video from a WDM...

Dear all, I've got a video capture device. Device manager shows "nVidia WDM Video Capture (universal)" driver in "Sound, video and game controllers" category. Also, Windows Movie Maker, and other standard video capture tools can record video from the device. But, I've got no idea how to read transmitted data in a C# application. All I'm gonna do is to show the real-time movie on an appropriate control on my form.

Hi, I am working on an access app and need to capture still images from a monitor connected to medical equipment. The video out port on the monitor is connected to a video card in the computer that will run my app so I am assuming I can capture this image by using video for windows apis? I simply want a button on a form that saves the image to disk in bmp or jpg format. Has anyone got an example of this? Thanks in advance, Ghostrider.

Hi Everyone, Do any of you gurus out there have any suggestions regarding capturing audio/video from a video capture card in C#. Although I've written other programs, I've never worked with audio/video sources before. I've seen other people recommending DirectShow.NET. Is this one of the more popular libraries to use? Would anyone recommend other third- party libraries? Thanks,
