XL: Can't Change Size or Position of Object in Custom Dialog

• Microsoft Excel for Windows 95, versions 7.0, 7.0a
• Microsoft Excel for Windows, versions 5.0, 5.0c
• Microsoft Excel for the Macintosh, versions 5.0, 5.0a

SYMPTOMS

In Microsoft Excel, you cannot use the Width, Height, Top, or Left properties of the DrawingObjects object to change the size or position of an object in a custom dialog box while the dialog box is displayed.

NOTE: This limitation does not apply to objects in UserForms in Microsoft Excel 97 for Windows or Microsoft Excel 98 Macintosh Edition.

CAUSE

This is by design in Microsoft Excel. You can move and size an object on a dialog sheet, and the object is displayed with this size and position when you display the dialog box. However, because a dialog box is not updated during an event macro (only after the event macro finishes), you cannot dynamically move or resize an object in the dialog box while the dialog box is displayed.

Note that you also cannot change the size or position of a custom dialog box when you use the Show method to display the dialog box.

Example of Visual Basic Procedure

For an example of using this method, do the following:

1. On a new worksheet (Sheet1), insert a picture in the range A1:C6.

2. On the Tools menu, click Options. Select the View tab, and under Window Options, clear the Gridlines check box. Click OK. Select the Picture, and click Copy on the Edit menu.

3. On the Insert menu, point to Macro, and then click Dialog. On the Edit menu, click Paste. Drag the picture to the dialog box. Click the Formula bar, and enter the following formula:

         =Sheet1!$A$1:$C$6
   

4. Size the picture on the dialog box as desired. The picture on the dialog box is now linked to the picture on the worksheet (Picture 1).

5. On the Forms toolbar, click the Create Button button. Drag on the dialog box to create a button (Button 5). Select the button, and click the Edit Code button on the Forms toolbar. In the new module, enter the following code:

         ' Code assigned to Button 5.
         Sub Button5_Click()
             ' Change width and height of picture.
             With Worksheets("Sheet1").DrawingObjects("Picture 1")
                 .Width = 30
                 .Height = 40
            End With
         End Sub
   
         ' Macro to display dialog box.
         Sub Display_Dialog()
             DialogSheets("Dialog1").Show
         End Sub
   
   

6. On the Tools menu, click Macro. In the Macro Name/Reference list, select Display_Dialog, and click Run.
