Since I do some Compact Framework programming on the side. I ran into the problem on how to do full screen applications on WM. Due to our background as “third level developers” we got a pretty good framework for C# Compact Framework programming and there I found the good old HHTaskBar “Hack”.
public static class TaskBar { private static IntPtr taskbar; [DllImport("coredll.dll", EntryPoint = "FindWindowW", SetLastError = true)] private static extern IntPtr FindWindowCE(string lpClassName, string lpWindowName); [DllImport("coredll.dll")] private static extern IntPtr ShowWindow(IntPtr hWnd, int visible); [DllImport("coredll.dll")] private static extern bool EnableWindow(IntPtr hwnd, bool enabled); /// <summary> /// hides windows taskbar /// </summary> public static void HideTaskbar() { taskbar = FindWindowCE("HHTaskBar", null); ShowWindow(taskbar, 0); EnableWindow(taskbar, false); } /// <summary> /// shows windows taskbar /// </summary> public static void ShowTaskbar() { ShowWindow(taskbar, 1); EnableWindow(taskbar, true); } }
This is fine,… but if the app crashes or you forget to implement the “ShowTasbar” function your TaskBar is gone (till the next cold reset). So I searched and found the following “lightweight” way to “hide” the TaskBar.
public static void FullSize(Form frm) { frm.WindowState = FormWindowState.Maximized; frm.Size = Screen.PrimaryScreen.WorkingArea.Size; frm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; }
Only tested for WM 5.0, 6.0 and 6.5!
