Hook the message box from your application

hHook = SetWindowsHookEx (WH_CALLWNDPROC,
                               (HOOKPROC)HookProcedure,
                               NULL,
                               GetCurrentThreadId ()/*NULL*/);

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()

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.

can any one tell me where i did wrong.

{
............
..
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.
