XL98: Redraw Problem Changing Visibility of Object on Dialog Box (184848)

WORKAROUND

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. To work around this problem, use a UserForm instead of a Microsoft Excel 5.0 dialog sheet. UserForms are new in Microsoft Excel 98. A UserForm is more flexible and offers more functionality than a Microsoft Excel 5.0 dialog sheet.

If you must use a Microsoft Excel 5.0 dialog sheet, you can use an alternative method. When you change the Visible property for the shape, close the dialog sheet, and then display it again. This forces Microsoft Excel to redraw the screen, which causes the border around the shape to appear correctly. The following example forces Microsoft Excel to do this:

1. Create a new workbook.
2. Hold down the CONTROL key and click a sheet tab in the workbook. Click Insert on the shortcut menu that appears.
3. Click MS Excel 5.0 Dialog and click OK.
4. Click Rectangle on the Drawing toolbar and draw a rectangle on the dialog sheet. (If the Drawing Toolbar is not displayed, point to Toolbars on the View menu and click Drawing.)
5. For the caption for the OK button, type "Toggle" (without the quotation marks), and then click the dialog frame to deselect the button.
6. Press OPTION+F11 to start the Visual Basic Editor.
7. On the Insert menu, Click Module.
8. Type the following code in the module:

          Sub Main()
   
              Dim contin
              'Set the flag to True.
              contin = True
   
              'Continue to show the dialog sheet while Contin is set to
              'True.
              Do While contin
                  contin = DialogSheets(1).show
              Loop
   
          End Sub
   
          Sub Toggle()
   
              'Toggle the Visible property of the Rectangle on the
              'dialog sheet.
              DialogSheets(1).Shapes("Rectangle 4").Visible = _
                  Not (DialogSheets(1).Shapes("Rectangle 4").Visible)
   
          End Sub
   						

9. On the File menu, click "Close and Return to Microsoft Excel."
10. Hold down the CONTROL key and click the Toggle button. Click Assign Macro on the shortcut menu that appears. Select the macro "Toggle" and click OK.
11. On the Tools menu, point to Macro, and then click Macros. Select the macro "Main" and click Run.

The dialog sheet appears. Click the Toggle button to toggle the Visible property of the rectangle on the dialog sheet.
