Description: can you block focus of a form if clicked

HI
i was wondering if there was a way to block focus of a form.. for instance if you have two windows(forms) open and one is active(has focus) and you click the other one, is there a way to make it not take focus or become the active window?

im working in V C++

I don't think that u can do that it comes made in your computers code. So i guess the only way to do that is to learn 'command prompt' or your computers code which could be messy if u don't know what ur doing. -_-

You need to use the Windows API for that. If you don't know what it is, you're probably shouldn't be using it yet. :)

If you've used it before, read more about the EnableWindow function on the MSDN.

And disgregard Shonoby's first post, it has no factual information whatsoever.

Putting this in the window's WndProc works for me. It still allows you to activate the window by the keyboard (ALT+TAB), while blocking it with the mouse.

CODE

case WM_MOUSEACTIVATE:
{
SetActiveWindow(GetActiveWindow());
return MA_NOACTIVATEANDEAT;
}
break;

thank you.

yeah i was pretty sure Shonoby did know what he was talking about..

ill try the EnableWindow too but how do you use the code adeyblue added in a WndProc?

In a skeleton window procedure, something like this

CODE

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_MOUSEACTIVATE:
{
SetActiveWindow(GetActiveWindow());
return MA_NOACTIVATEANDEAT;
}
break;
case WM_COMMAND:
{
// Whatever code here
}
break;
case WM_CREATE:
{
// Whatever code here
}
break;
// Handle other cases, then
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
