Write a program to control the hiding and display of other application Windows:

1. register the hotkey

 

Bool registerhotkey (
Hwnd, // window to receive hot-key notification
Int ID, // identifier of Hot Key
Uint fsmodifiers, // key-modifier flags
Uint VK // virtual-key code
);

Registerhotkey (this-> m_hwnd, 0xa002, mod_control + mod_alt, 79 );

 

2. Use findwindow or find1_watpoint to find the hwnd of the application window.

 

3. process this hwnd in the hotkey.

 

Call showwindow (hwnd, sw_hide); // or sw_show to hide and display the application window corresponding to this hwnd.

 

4. The pseudocode is as follows:

 

Cmainframe: Create (..)
{
If (! Cframewnd: Create (..))
Return-1;
Obtain the hwnd of the required program;
Register the hotkey;
Return 0;
}
Cmainframe: onkeydown (...)
{
If (equivalent to the registered hot key)
{
If (hide window)
{
Display window;
}
Else
{
Hide the window;
}
}
Cframewnd: onkeydown (..);
}
