To display a Windows Form
Add a Windows Form to your project. In this example, the Windows Form is called ReportPicker.
In the Startup event handler of your project, create a new instance of the form and call the ShowDialog method to display the modal form.
Dim reportPicker As New ReportPicker reportPicker.ShowDialog()
ReportPicker reportPicker = new ReportPicker(); reportPicker.ShowDialog();
You can also use the Show method to show a non-modal form.
