SUMMARY

This step-by-step article describes how to switch between forms by using the My.Forms object in a Microsoft Windows Forms application that is built by using Microsoft Visual Basic 2005.

INTRODUCTION

To display a form in a Windows Forms application that is built by using Visual Basic 2005, use either the Show method or the ShowDialog method of the form.

Note Use the My.Forms object to acquire a reference to a form.

When you use the ShowDialog method, the form is displayed as a modal dialog box. Alternatively, you can set the Visible property of the form to True to display a form.

To hide a form, use one of the following methods:

• Use the Hide method.
• Set the Visible property to False.
