GUI events

C# Windows application

Mouse Events The mouse is a primary interface for doing graphics in Visual C# Express. A program needs to recognize mouse events in controls. Many controls recognize mouse events.

Mouse Events private void panel1_MouseDown(object sender, MouseEventArgs e) { switch (e.Button) { case MouseButtons.Left: label1.Text = "Left"; break; case MouseButtons.Middle: label1.Text = "Middle"; break; case MouseButtons.Right: label1.Text = "Right"; break; } label2.Text = Convert.ToString(e.X) + "," + Convert.ToString(e.Y); }

Generating Irish Grid letter The Irish National Grid is a coordinate reference system for Ireland. It is measured in metres with a range (0,0) to (500,000,500,000). For ease of reference a set of labelled grid squares are used. These are A to Z with no I. The code below accepts an ING coordinate and returns the grid square that contains the coordinate.

Generating Irish Grid letter See See code in notes section Tasks – Get input data from a CSV file – Write results to a CSV file – Prompt used for input/output files – Allow user to enter number specifying the number of digits in the output (0-6)
