XL98: ShowDataForm Method Fails If Data Can't Be Found (191115)


The information in this article applies to:

  • Microsoft Excel 98 Macintosh Edition
This article was previously published under Q191115

SYMPTOMS

In Microsoft Excel 98 Macintosh Edition, when you use the Visual Basic ShowDataForm method, you may receive the following error message:
Run-time error '1004':
ShowDataForm method of Worksheet class failed

CAUSE

This error occurs because Microsoft Excel is unable to find a data list on the worksheet you specified in the Visual Basic statement.

When you use the ShowDataForm method, Microsoft Excel looks for the data list in two places:
  • The defined name "Database." If a range has been defined as the database, Microsoft Excel will display the data form, and the data in that range will be accessible.
  • Cells A1:B2 on the specified worksheet. Microsoft Excel will attempt to find a list whose upper-left corner lies in the range A1:B2. If a list is found, Microsoft Excel will display the data form and the data in the list will be accessible.

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, define your data with the defined name database, without quotation marks, or move your data so that its upper- left corner is located in any of the four cells in the range A1:B2.

To define your data with the defined name "database", do the following:
  1. Select the range that contains your data.
  2. On the Insert menu, point to Name, and then click Define.
  3. In the Name box, type <Sheetname>!Database, where <Sheetname> is the name of the active worksheet.
  4. Click OK to accept the change.
When you execute the ShowDataForm method and specify the worksheet, the data form will be displayed with the correct data.

To automate the above process, select the data that you want to be included in your database (including column headings), and include the following in your Visual Basic procedure: 
   ActiveWorkbook.Names.Add Name:=ActiveSheet.Name &amp; _
      "!Database", RefersToR1C1:=Selection
   ActiveSheet.ShowDataForm

STATUS

This is by design of Microsoft Excel 98 Macintosh Edition.
