How to get hwnd of the window. Thanks for advance.
It's can be obtained if you call CreateWindow. What if i dont call this function. What can i do?
with due respect. sulacco

How about you look at the MSDN help for CWnd, and realize there is a method called GetSafeHwnd()?

I hope that helps,

Vincent

If I understand correctly, you want to get the handle to a window that is already created, rather than creating a new window with CreateWindow.

If the window is a top-level window, you can find it using EnumWindows. If you have the handle for a child of the window, you can call GetParent to get it.

There is a problem. I'm not using MFC to use GetSafeHwnd().

Second: I'm not called CreateWindow. Code look's like this:

...

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{

MSG msg;
First();
OnHook();


while( GetMessage( &msg, NULL, 0, 0 ) ) {
TranslateMessage( &msg );
DispatchMessage( &msg );
}


return 0;
}
...
It's just bare skeleton. but in next to this function i have to get hwnd.

You have no window - why do you need hWnd? Most API calls have parameter hWnd, but it could be NULL, I think. What API calls do you use namelly?
Use NULL or hWnd of the desktop - HWND_DESKTOP. Or may be create dummy invisible window using CreateWindow?
