I would recommend you to test your graph using Graphedit and the construct it programatically.There is are a lot of reasons that could cause errors in your code. :) Life is a stage and we are all actors!

He uses CScrollView to display the images so the code will show you how to manage the scrolling aspects, but whatever you say, I'm sure you are correct. led mike

This comes with a splitter[^] called a sizer bar. I used to use this stuff all the time in MFC UI applications. led mike

"Graphics g = pictureBox1.CreateGraphics();" That is a bad idea unless you're drawing something you want to erase, like a rubber band. Painting should take place in the paint event. And, at this point, you should just draw your bitmap in the paint event, then draw on it. Christian Graus Please read this if you don't understand the answer I've given you.

I did something similar to it sometime back. check this, this and this the fruits of your success will be in direct ratio to the honesty and sincerity of your own efforts in keeping your own records, doing your own thinking and, reaching your own conclusions. ..surviving in autumn..in love with spring..

Windows Installer packages should always 'install' every component that they include. The Windows Installer runtime will decide whether or not to install a file. It records every package that installs a component and only removes the component when no references remain. Be very aware that Windows Installer makes these decisions on a component GUID basis, not by using file paths. If one file has a different GUID in different packages, when one is uninstalled, Windows Installer will decide that the file is no longer used and will remove it, breaking the other installation. For this reason any shared files installed to the same location should always have the same GUID. The only way to do this in Visual Studio's setup packages, that I'm aware of, is to create a Merge Module containing the shared components and include that Merge Module in all install packages. I believe Windows Installer counts references to assemblies installed in the GAC separately, so I think it's safe to install the same assembly to the GAC using different references. Still, it's better to follow the same pattern throughout. In general, you should follow the supplier's advice for installing any third-party components. That may well mean running their installer before yours. Best practice in my view is to install everything into your own private binary folder. You should avoid strong naming, in my opinion, as that will cause lookups in the GAC even if the file is in the binary folder. If you aren't versioning your assemblies correctly, an administrator can break your application by putting the assembly in the GAC, as the GAC takes precedence over local folders for strong-named assemblies.

You need to specify some attributes for the property to get the collection editor on VS IDE.

So it means the target instance is not from the type you think it is. In debug mode you could confirm. If you are lost, you could send me a small sample (complete solution, no binaries in the zip file please) to reproduce your issue and I will quickly check.

you can start from here[^] (it is a very simple example) or you can find the example you prefere here http://www.codeproject.com/opengl/[^] :-D:-D Russell

It should be a top-level window.  The main frame window should work. One way to get it is AfxGetApp()->GetMainWnd()->GetSafeHwnd() Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Either DirectSound or the Windows Multimedia APIs will work.  If you choose DirectSound then download the latest DirectSound SDK and you'll find sample apps to get you started, along with documentation.  The "CaptureSound Sample" is a good start :) Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Hi Mark, I think I am understanding..., let me see if I have this right, so basically I override InActive and Active, I dont have to write anything in there. By overriding them they wont be able to trigger the thread to start and stop, so then in my callback I go in and pretty much do what the DoBufferProcessingLoop is doing and once I get IMediaSample *pSample I just populate it with the image data I have and we are ready to go? Did I get that right? Once again thanks

Where are you getting that frame rate from? if its a camera you might be able to get away with differences on the images, which would be a small performance hit but not nearly as much as converting it to PNG. My advice if you do wish to compress the images send the data to a grid for conversion to bitmap and then to lossless PNG. -Steven Hicks CPA CodeProjectAddict Actual Linux Penguins were harmed in the creation of this message.

Here's the place to start: Writing DirectShow Filters[^] The filter type you want is a capture filter. The section of the SDK specifically for that is Writing Capture Filters[^] I highly recommend starting with the base classes included with the SDK. It saves alot of work. There's also working filter samples in the Platform SDK if you want some code to get you started. The Push Source Filters Sample[^], although not a true capture filter, may be a good place to start. If you haven't already, download the Platform SDK - all the DirectShow stuff is there :) Mark "Posting a VB.NET question in the C++ forum will end in tears." Chris Maunder
