BUG: A Picture Box Containing Labels May Not Repaint Correctly

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

SYMPTOMS

A picture box that contains labels and is larger than the screen size does not repaint correctly.

STATUS

Microsoft has confirmed this to be an issue in the Microsoft products listed at the beginning of this article. Microsoft is researching this issue and will post new information here in the Microsoft Knowledge Base as it becomes available.

WORKAROUND

Use text boxes without borders - BorderStyle set to None - and a BackColor set to the same color as the label to substitute for the labels. The text boxes should be made read-only.

MORE INFORMATION

Steps To Reproduce Problem

1. Start a new project. Form1 is created by default. Place a picture box on the form, and then place a label control inside the picture box.

2. In the Properties window for the picture box, change the Height property to a large value, such as 20000.

3. Drag the picture box up until you can view the lower border. Notice that the section of the picture box that was below the screen does not correctly repaint. When the label is removed, the problem goes away.
