But where should I put messagebox related info to SetWindowsHookEx(...)

Put them in the HookProcedure
The prototype for the HookProcedure is
LRESULT CALLBACK HookProcedure(HWND hWnd,UINT uMsg,WPARAM wParam,LPARAM lParam)

You will also have to use these at appropriate places:
CallNextHookEx()
UnHookWindowsHookEx()

Somethings seem HARD to do, until we know how to do them.

The second thread calls the member function of CAuthen. the second thread calls authen.CheckAuthentication(); in theat member function, i called a dialog using DoModal(); after displaying the dialog, my application gives some
Assertion Error.

............
..
public:

CAuthenDlg auth_dlg;
..

public :

void checkAuthentication();

};

void CAuthen :: checkAuthentication()

Hi All,

I have created custom log file and its key is added to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\CustomLog. But if I give a path value greater than say 100 characters for File key under CustomLog windows is not taking this path. Is there any restrictions on path length for File key in registry?

if what u want is to run the exe from the clicent, use ShellExecute.

ShellExecute( 0, _T("open"), _T("c:\\WINDOWS\\system32\\calc") ,0,0,SW_SHOW);

un the place of c:\\WINDOWS\\system32\\calc, put the full path of ur exe.

'
Run your Socket Server Program on CMD line.. and (If you Know, or Idea about sockets) you have to to create a client program and connect to ip of your computer system and post at which socket server is listening.

if you don't know the ipaddress of your computer you can use loopback ipaddress i.e. (127.0.0.1)

Is it the strings you mean when you say words.
If affirmative, there is a function itoa() that can be used to do this.

If you mean a DWORD value:
A DWORD value is an 32 bit unsigned integer

If WORD:
A WORD is a 16 bit unsigned integer.

Think about what you want to do. Think about how your brain processes it. Then think about how to reproduce that in code.
