how can i imitate zhider (hides any windows app)

how are they doing the hides ? http://www.zinious.com/products/ZHider/

like it can hide any window programs from showing up in task开发者_开发百科bar and system tray.

how can i do this programmatically in vb6, .net , c++ ?

are there other similiar tools to zhider ? open source ?

thanks.

Most likely they are using PInvokes, you can check out a full reference on this site. Example:

You can use ShowWindow to hide a window, even if your app didn't create it! Simply call ShowWindow(hWnd, 0);

If you just need this done once for your own personal use, check out AutoHotKey, it has a WinHide command. http://www.autohotkey.com/. If you need to implement this in your app, check out the source code for AutoHotKey.
