WinForm implementation minimized to the system pallet Method Example

This article describes the WinForm implementation to minimize the system tray method. Share to everyone for your reference. The specific analysis is as follows:

There's a control called NotifyIcon.

1, build a WinForm project, other operations skipped.

2, pull a NotifyIcon control, set the property visable to False, in the Text property on a random fill in some files.

3, the implementation of the form of the SizeChanged event, the code is as follows:

?

1 2 3 4 5

if (this. WindowState = = formwindowstate.minimized)//Determine whether to minimize {this. ShowInTaskbar = false; Do not appear in system taskbar notifyicon.visible = true; Tray icon Visible}

4, the implementation of the NotifyIcon control DoubleClick event, the code is as follows:

?

1 2 3 4 5 6

if (this. WindowState = = formwindowstate.minimized) {this. ShowInTaskbar = true; displayed in the system taskbar this. WindowState = Formwindowstate.normal; Restore form notifyicon.visible = false; Tray icon Hide}

Examples:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 This is the same as the same as the same as the same as the same as the same as the other, at the same ().

WindowState = = formwindowstate.minimized) {this. Show (); This. ShowInTaskbar = true; This. WindowState = Formwindowstate.normal; Notifyicon1.visible = false; } public void Exitselect (object sender, System.EventArgs e) {//Hide the icon in the tray program notifyicon1.visible = false;//Shut down system this. Close (); This. Dispose (TRUE); #endregion private void Form_main_sizechanged (object sender, EventArgs e) {if (this. WindowState = = formwindowstate.minimized)//Determine whether to minimize {notifyicon1.visible = true; Hide (); This. ShowInTaskbar = false; Initializenotifyicon (); } }
