Display the minimal icon of the winform application on the taskbar and provide a right-click menu

1. First, set the MDI form showintaskbar to true. In vs2008, the default value is true;
2. Add the policyicon and its contextmenustrip controls respectively;
3. Then, point the contextmenustrip attribute value of yyicon to contextmenustrip, and specify the icon of notifyicon as a *. Icon image file to display in the taskbar;
4. Add a mousedoubleclick event named yyiconsystem_mousedoubleclick for policyicon;
5. Add a sizechanged event named mainform_sizechanged to the MDI form;

The above can basically fulfill our corresponding needs, and then we can achieve it. Here, I want the application to display no corresponding icon in the taskbar when it is in the application, and display its icon only when it is minimized, and right-click the icon on the taskbar to provide simple functions (hide, show, close, about), double-click the icon to restore the application form.

 

DetailsCodeAs follows:

 

Code
// Form Loading
Private   Void Mainform_load ( Object Sender, eventargs E)
{
// .
This . Policyiconsystem. Visible =   False ;
}

// Double-click the taskbar icon to restore the window
Private   Void Notifyiconsystem_mousedoubleclick ( Object Sender, mouseeventargs E)
{
If ( This . Windowstate = Formwindowstate. Minimized)
This . Windowstate = Formwindowstate. normal;
This . Activate ();
This . Policyiconsystem. Visible =   False ;
}

// Add form minimization event
Private   Void Mainform_sizechanged ( Object Sender, eventargs E)
{
If ( This . Windowstate = Formwindowstate. Minimized) // Minimize
{
This . Showintaskbar =   False ;
This . Policyiconsystem. Visible =   True ;
}
}

# RegionBegin _ minimized right-click the icon menu

Private   Void Menuitemicon_hide_click ( Object Sender, eventargs E)
{
// This. windowstate = formwindowstate. minimized;
This . Hide ();
This . Showintaskbar =   False ;
This . Policyiconsystem. Visible =   True ;
}

private void menuitemicon_show_click ( Object sender, eventargs e)
{< br> This . show ();
This . windowstate = formwindowstate. normal;
This . activate ();
}

Private VoidMenuitemicon_about_click (ObjectSender, eventargs E)
{
//
}

Private VoidMenuitemicon_exit_click (ObjectSender, eventargs E)
{
Applicationexit (Null);
}

# EndregionEnd _ minimized right-click the icon menu
