Replace the above code with this.

// Minimize All Windows<br />
	::PostMessage(FindWindow("Shell_TrayWnd", NULL)->GetSafeHwnd(), WM_COMMAND,MAKELONG(415, 0), 0);<br />
<br />
// Undo Minimize All Windows<br />
	::PostMessage(FindWindow("Shell_TrayWnd", NULL)->GetSafeHwnd(), WM_COMMAND,MAKELONG(416, 0), 0);

Use ::FindWindow instead of FindWindow
FindWindow return CWnd
::FindWindow return HWND

OR
or Cast CWnd pointer to HWND

Let me give you an overview.
Should i create a saparate thread when a user double clicks on a online contact to chat with him?
Can someone provide me help or any resourse regarding this project? I have done work in socket programming. So i have no problem in that part. I just want high level logic for implementing messenger.
Please help me
Thanks

I dont think there is a need for a thread for each session, unless you have special processing logic for each session. For the UI, a modeless dialog should be enough for each session.

How to hook windows'socket functions using SetWindowsHookEx function

Please help me!
I am writing a small program that I want to uses the Hook function for windows'socket functions like recv, send,...
I have tried to uses the function SetWindowsHookEx:
HHOOK SetWindowsHookEx(
int idHook,
HOOKPROC lpfn,
HINSTANCE hMod,
DWORD dwThreadId
);
But it seems to have too fews argument.It has only 4 arguments: one for the type of hook, one for the address of the function to be hooked, one for the instance that contain the function, one for the thread that the function is running in. I cannot find out where to put the address of the new function that I want to put into the hook chain.
Please show me where to put the new function's address, how to uses the SetWindowsHookEx function and how its argument work.
Thank you very much!

lpfn parameter is the HOOKPROC. you can pass the function handle there.

But i think you are trying to do something like sniffing right? Search codeproject for "Sniffer" you will get plenty of tools with source code.

SetWindowsHookEx allows us to HOOK these types

WH_CALLWNDPROC Thread or global 
WH_CALLWNDPROCRET Thread or global 
WH_CBT Thread or global 
WH_DEBUG Thread or global 
WH_FOREGROUNDIDLE Thread or global 
WH_GETMESSAGE Thread or global 
WH_JOURNALPLAYBACK Global only 
WH_JOURNALRECORD Global only 
WH_KEYBOARD Thread or global 
WH_KEYBOARD_LL Global only 
WH_MOUSE Thread or global 
WH_MOUSE_LL Global only 
WH_MSGFILTER Thread or global 
WH_SHELL Thread or global 
WH_SYSMSGFILTER Global only

AFAIK it is not possible to hook socket using this API.

You could look at the following http://www.codeproject.com/dll/apihijack.asp[^] which has a simple example showing how to hook API's.

Will you please clarify what do you mean by "the window would not smooth."
Are you using RedrawWindow() in your code many a times?
