Alt+Tab?

Question

Hi I'm writing a program that basically just sits on the desktop in a borderless form. I have everything working as I'd like except for the 'alt-tab' function of windows. Does anyone know of a way to remove a form from the 'alt-tab' list of programs? Thanks

For whatever reason removing the form from the task bar doesn't also remove it from this list. What you gave me works though - thanks a lot.

I'd have thought that setting the Form's ShowInTaskbar property to false would remove it from the Alt-Tab list as well ? However if it doesn't then try these Win32 calls: using System.Runtime.InteropServices; ........ [DllImport(user32.dll)] static extern int GetWindowLong( IntPtr hWnd int nIndex); [DllImport(user32.dll)] static extern int SetWindowLong( IntPtr hWnd int nIndex int dwNewLong); const int GWL_EXSTYLE = -20; const int WS_EX_TOOLWINDOW = 0x80; ....... IntPtr hWnd = this.Handle; int dwExStyle = GetWindowLong(hWnd GWL_EXSTYLE); SetWindowLong(hWnd GWL_EXSTYLE dwExStyle | WS_EX_TOOLWINDOW);
