XL98: Dialog Box Show Method Fails with Reference Type Edit Box (192905)

SYMPTOMS

In Microsoft Excel 98 Macintosh Edition, when you attempt to display a dialog box over another dialog box, and the first dialog box contains a text box that has the Reference or Formula "Edit Validation" type, you may receive the following error message:

Run-time Error '1004':
Show method of Dialogsheet class failed

This error occurs when the second dialog box is displayed during an event macro of a control on the first dialog box, and the first dialog box has not been unloaded.

The error message may be hidden behind your custom dialog box. Press E to dismiss the error and stop the running of your macro.

CAUSE

This is a known limitation with Microsoft Excel 5.0 style dialog boxes. You cannot stack a semi-modeless dialog box (any dialog box that has a Reference or Formula type edit box) on top of another dialog box.

WORKAROUND

To work around this limitation, use either of the following methods.

Method 1: Unload the First Dialog Box Before You Show the Second

Unload the first dialog box before you show the second dialog box (which contains the Reference or Formula type edit box).

Method 2: Use UserForms

Use UserForms instead of Microsoft Excel 5.0 dialogs. UserForms do not have this limitation.
