DOCUMENT:Q193401 29-SEP-1998 [vbwin] TITLE :BUG: Can't Change UserControl FontTransparent if Default = False PRODUCT :Microsoft Visual Basic for Windows PROD/VER:WINDOWS:6.0 OPER/SYS:WINDOWS KEYWORDS: ====================================================================== --------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0 --------------------------------------------------------------------- SYMPTOMS ======== When the FontTransparent property of a UserControl is programmatically set to True, the UserControl still behaves as if FontTransparent is set to False. The actual property value changes but the behavior does not. Once something has been printed on the control, the FontTransparent can be changed successfully. This problematic behavior occurs only if the FontTransparent property is set to False in design mode. RESOLUTION ========== The workaround for this problem is to always set the FontTransparent property of a UserControl to True in design mode. If the design mode value is True, it can be changed programmatically without incident. If it is set to False, the problems described above will occur. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. MORE INFORMATION ================ Steps to Reproduce Behavior --------------------------- 1. Create a Standard EXE project in Visual Basic. Form1 is created default. 2. Select Add Project from the File menu to add an ActiveX Control project to the project group. 3. Assign the Picture property of the UserControl to a large bitmap. 4. Set the FontTransparent property of the UserControl to False. 5. Add the following code to the UserControl's module: Private Sub UserControl_Click() FontTransparent = True Print FontTransparent FontTransparent = False Print FontTransparent FontTransparent = True Print FontTransparent End Sub 6. Close the UserControl window, and place an instance of the UserControl on Form1. 7. Run the project, and click on the UserControl. 8. Note that the first value printed on the control does not exhibit FontTransparent behavior. 9. Open the UserControl1 project and change the FontTransparent property of the UserControl to True, and then repeat step 7. Note that the behavior is correct.
