Setting the BorderStyle property of the Masked Edit control to None at design time results in an "Invalid property value" error at run time. In addition, setting the Mask property to anything and then setting the BorderStyle property back to Single causes unusual characters to appear in the Mask property.


The cause of the problem is unknown at this time.


There is no known work around at this time.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem has been corrected in Visual Basic version 4.0.


Steps to Reproduce Problem

  1. Start Visual Basic or from the File menu, choose New Project (ALT, F, N) if Visual Basic is already running. Form1 is created by default.
  2. From the File menu, choose Add File (ALT F, A), and add MSMASKED.VBX to your project.
  3. Place a Masked Edit control (MaskedEdit1) on Form1.
  4. Set the BorderStyle Property of MaskedEdit1 to 0 - None.
  5. From the Run menu, choose start (ALT, R, S), or press the F5 key to run the program.
  6. Visual Basic will generate an "Invalid Property Value" error. Click OK in the error message to return to Visual Basic.
  7. Set the Mask Property of MaskedEdit1 to #### and set the BorderStyle Property back to 1 - Single.
  8. Now check the Mask Property. It contains unusual characters, but it should still contain ####.
