This program will teach you how to create hooks and dynamically control the behavior, outlook or anything related to a window. This program shows subclassing for MSN Messenger, by setting up a hook and then dynamically adding Menu items to MSN Messenger and handling its behaviour to certain events. With this technique, you can virtually do anything to any window or application of which you do not have access to code. Subclassing and hooking can be VERY powerful when used properly. Please check it out and please vote (o= Thanks

I have no idea why this code got as many votes as it did. Its a simple win32 application which makes some api calls, hardly worth anything. (If this comment was disrespectful, please report it.)
Thankyou, Visual C, for your feedback on my code... yea you're right... just some silly bunch of win32 api calls... when I could've done some smart win64 api calls... yup.. dumb program...hardly worth anything, and who needs to know what subclassing is anyways, hah I bet people at microsoft feel stoopid writing programs and doing dumb win32 api calls..sheesh... mate u're right.. we all need a life.. thankyou so much for letting us know how great you are and how low we are :o) have a nice day

This doesnt work with Borland C++, or Unix C++. You should change the compatiblity of your article so people know what it works for. (If this comment was disrespectful, please report it.)
E-Man's right. It doesn't work with BC++ or UNIX C++. It would be helpful to actually compile the code in all of the compilers you claim it works on. It would make life easier for those of us that using these compilers.
Thanks. (If this comment was disrespectful, please report it.)
This is probly due to my lack of knowlegde in C++, but i cant make the menu drop down or do anything (events) (If this comment was disrespectful, please report it.)
How do i compile it ? It keeps saying: Error: Unresolved external '_main' reference from (my borland lib path) i use borland freecommandlinetools, and tried to compile with -tW in it. Could someone please tell me what command i must use.

im a fellow vb'er..could u make a subclass oCX for me..cuz the only that i can find that works is spyworks and that costs money :\ (If this comment was disrespectful, please report it.)
I haven't read much of your code by I have to commend you on nice, clean code. Well formatted. Something you dont see here often. (If this comment was disrespectful, please report it.)

GWL_WNDPROC Sets a new address for the window procedure. Windows NT/2000 or later: You cannot change this attribute if the window does not belong to the same process as the calling thread. (If this comment was disrespectful, please report it.)

Has anyone tried this in Visual Studio.Net? I opened the project and it does something weird with the IDE. The main window keeps flasshing, not sure what is happening here :)

Thank you so much for your precious article. I have a question. After registering a new menu, How can I get the menu message from it, when someone click it?
thank you. (If this comment was disrespectful, please report it.)
Thanks for the article. It is really helpful. I have a question. CAn we use this to detect any background window?
Also, CAn we use the same Shell_Hook for creating a hook to detect when a window closes. Because your program is to hook when MSN Messenger starts.
Thanks (If this comment was disrespectful, please report it.)
