Controls are not displayed on Windows Forms that are larger than the screen resolution (822497)


The information in this article applies to:

  • Microsoft Visual Basic .NET (2003)
  • Microsoft Visual Basic .NET (2002)

SYMPTOMS

When you run a Microsoft Windows application, a Windows Form that is larger than the screen resolution may not display all the controls. For example, if your Windows Form is 1024 X 768 and your screen resolution is 800 X 600, you may not able to see all the controls on the form.

CAUSE

This problem occurs because a Windows Form display on the screen is restricted to the current screen resolution settings. Therefore, the controls on a Windows Form are not displayed if you put the controls in a location that exceeds the current screen resolution settings. However, the controls are added to the Windows Form.

WORKAROUND

To work around this problem, enable the AutoScroll property of the Windows Form. To do this, follow these steps:
  1. In the Windows Form Designer, right-click the form and then click Properties.
  2. In the Properties window, set the AutoScroll property to True.

    A scroll bar is added to the form. You can use the scroll bar to work with the controls that were not previously displayed.

STATUS

This behavior is by design.

  1. On the Display Properties window, click Settings.
