Hey!

On a side note: having a button that gets enabled when a correct password is entered makes it a bit easier to guess the password by bruteforce (or/and maybe other methods) because one only has to write a program that enters a password and then checks the state of the button, if it is disabled, it tries the next possible password and checks the button again until the button becomes enabled... althorough you can add a -let's say- 3 seconds pause if a wrong password is entered before the user is allowed to enter the next password, this makes it take much much more time to hack.

Aside of this, did you try handling WM_KEYDOWN? Did it work?

case WM_CHAR : 
{
	switch(LOWORD(wParam))
	{
		case VK_RETURN:
			MessageBox(hWnd, "Enter Pressed", NULL, NULL);
	}
}

case WM_KEYDOWN : 
{
	switch(LOWORD(wParam))
	{
		case VK_RETURN:
			MessageBox(hWnd, "Enter Pressed", NULL, NULL);
	}
}
