Well, that is somewhat complex, you need to change the WndProc of the target process. You need to write a DLL that will handle WndProc functionality.

You are new to Windows Programming, so I recommend you to keep programming your 'windows' only, and dont disturb others. ;)
There is so much ground you need to cover up... Windows seems to have easy UI, but programming it is quite difficult.

Well, you have picked an advance topic being a novice anyway. This topic has been discussed in various ways many time. There are 2 types of hooks
1) Application Wide (for hooking particular application)
2) System Wide (for monitoring entire system)
Search for "Application wide hook" and you'll find plenty of information. Also, have a look at this (http://www.dev-archive.com/Cpp/W-P/system/misc/article.php/c5733/) for application wide hook reference.
But be careful, working at low level can destable your system as well, in case you make some mistake, which goes unidentified.

Well, other than hooking, replacing WNDPROC is also a good option... :thumb:

Hi ajay & Ejay,
Can you tell me in detail about the WNDPROC? Can you suggest me which one will be a feasible solution for this??
Thanks & Regards,

I dont not recommend you to play with Windows (programming) like this. First you should know how to process messages of your own windows, own windows in different processes (IPC mechanisms) and so on.
Using windows hooks or changing remote process' WNDPROC is an advanced programming technique and should (must) not be the starting point for learning WP.
