What technologies/libraries/protocols I need to study to develop a video system similar to skype or MSN messenger? I prefer coding in C++. To be more specific: How do I capture the video feed from the webcam? And how do I play it back? How do I capture sound? And how do I play it back? How do I stream it over the internet? Do I use sockets?

I can see they use a flash player to stream the video feeds from the server and to send the web cam stream to server. What flash library I have to use to accomplish that? And what about the back-end? How do I receive and broadcast the various video feeds? I am not asking for you to give me the complete code, just point to the right technologies and I will do my research. Thanks Ian

I found out the problem. I was doing something wrong in my code. Too much detail to explain here.

You have 2 options 1) You have to set the WS_OWNERDRAW style. Check the MSDN library docs for ownerdrawn controls. This allow you to draw the labels but not the empty space where there are no labels. So this option may not suit you at all. 2) If you want to customize the entire area of the tab, including borders, you have to subclass the tab control and handle WM_PAINT yourself. I strongly recommend this article that explains how to do this: http://www.codeproject.com/tabctrl/customtab.asp

when I create the edit as a child window???? But it blinks when it's created through a dialog resource. I have used spy to view the window style of my edit inside a normal window, and the edit control inside a dialog box. Both styles are exactly the same. Why doesn't the caret blink? Thank you for any help

How can I change the tooltip of the restore button on the titlebar to display "Full screen" instead of "Restore Down"?
