FT leopard brother, you give the "left mouse button, pop up the contextMenu" program-Windows development-. NET tutorial-micro

Because there is no IDE environment, the program should be as simple as possible.
Don't talk about it. Check the program.
Using System;
Using System. Windows. Forms;
Using System. Drawing;
Class useonpaint: Form
{
Public useonpaint ()
{;}

Static void Main ()
{
Application. Run (new useonpaint ());
}

Protected override void OnMouseUp (MouseEventArgs e)
{
If (e. Button = MouseButtons. Left) test (e );

}
Private void test (MouseEventArgs e)
{
ContextMenu m = new ContextMenu ();
This. ContextMenu = m;
// Create MenuItem objects.
MenuItem menuItem1 = new MenuItem ();
MenuItem menuItem2 = new MenuItem ();

// Set the Text property.
MenuItem1.Text = "New ";
MenuItem2.Text = "Open ";
