Hi circlesoft Thank you very much for your immediate reply. Actually our main aim of our project is to develop a software for dual monitor support in a wireless/wired environment without any need for special cards.But it seemed to take a very long time and also beyond our scope of our knowledge.SO we decided to develop a similar application in a different way. First client will listen to server and when it is connected,server sends resolution parameters X and Y.Then client should pop up a directx window of that resolution. Secondly,Server will look for updates in desktop ,capture them and send them to client.Then client will receive those updates and display in directx window in 8*8 blocks. Regarding pixels,what you said is true. Can you please tell me how can we send/receive pixel colors through DirectPlay?I found a very few samples regarding DirectPlay related to my project. Thank you in advance Hema. [edited by - hema on March 29, 2004 9:56:00 AM]
