BUG: UserControl's ContainedControls Do Not Inherit ScaleMode (188552)


The information in this article applies to:

  • Microsoft Visual Basic Learning Edition for Windows 5.0
  • Microsoft Visual Basic Learning Edition for Windows 6.0
  • Microsoft Visual Basic Professional Edition for Windows 5.0
  • Microsoft Visual Basic Professional Edition for Windows 6.0
  • Microsoft Visual Basic Enterprise Edition for Windows 5.0

This article was previously published under Q188552

SYMPTOMS

A control in the ContainedControls collection of a UserControl reports its dimensions and placement in Twips regardless of the ScaleMode setting of the UserControl or the Parent. Because ScaleMode is inherited elsewhere in Visual Basic, this behavior is inconsistent.

RESOLUTION

Programmatically, you can use the ScaleX and ScaleY methods to convert the property values from one ScaleMode to another. Note that this does not change the actual ScaleMode of the properties. ScaleX and ScaleY are merely conversion functions. There are no workarounds for how the properties are reported in the Property Windows.

STATUS

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

Steps to Reproduce Behavior

  1. Start a new Standard Exe project in Visual Basic. Form1 is created by default.
  2. Set the ScaleMode property of Form1 to 6 - Millimeters.
  3. Add a UserControl to the project.
  4. Set the ScaleMode property of the UserControl to 6 - Millimeters.
  5. Set the ControlContainer property of the UserControl to True.
  6. Close the UserControl window.
  7. Place the UserControl on Form1.
  8. Drag a CommandButton onto the UserControl.
  9. Drag a CommandButton onto Form1.
  10. View the Properties for the UserControl (such as Width) and note that all coordinates are reported in millimeters.
  11. View the Properties for the two CommandButtons. Compare the Width of the CommandButton placed inside the UserControl with the CommandButton placed onto the Form. Notice the Width of the CommandButton placed inside the UserControl is in Twips whereas the Width of the CommandButton placed on the Form is in millimeters.
