Example

[Visual Basic, C#, C++] The following example lists numbers in a list box on a form. Each time you click button1, the application adds another number to the list.

[Visual Basic, C#, C++] The Main method calls Run to start the application, which creates the form, listBox1, and button1. When the user clicks button1, the button1_Click method adds numbers one to three to the list box, and displays a MessageBox. If the user clicks No on the MessageBox, the button1_Click method adds another number to the list. If the user clicks Yes, the application calls Exit to process all remaining messages in the queue and then to quit.

[Visual Basic, C#, C++] The example assumes that listBox1 and button1 have been created and placed on a form.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of Run. For other examples that might be available, see the individual overload topics.

      ' Increments the counter and adds the number to the list box.

   ' The user wants to exit the application. Close everything down.
