Gets the screen coordinates of the mouse pointer.
public:
property System::Drawing::Point MousePos { System::Drawing::Point get(); };
public System.Drawing.Point MousePos { get; }
member this.MousePos : System.Drawing.Point
Public ReadOnly Property MousePos As Point
A Point representing the screen coordinates of the mouse pointer.
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Control.HelpRequested event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.
To run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. Then name the instance Control1
and ensure that the event handler is associated with the Control.HelpRequested event.
private void Control1_HelpRequested(Object sender, HelpEventArgs e) {
System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "MousePos", e.MousePos );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "HelpRequested Event" );
}
Private Sub Control1_HelpRequested(sender as Object, e as HelpEventArgs) _
Handles Control1.HelpRequested
Dim messageBoxVB as New System.Text.StringBuilder()
messageBoxVB.AppendFormat("{0} = {1}", "MousePos", e.MousePos)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"HelpRequested Event")
End Sub
You can use this information to provide help based on the position of the mouse pointer.
