XL2002: DDE Clients Cannot Use a RUN Command to Run an Inline Macro After a Security Update

This article has been archived. It is offered "as is" and will no longer be updated.
Client applications can use Dynamic Data Exchange (DDE) to issue a macro RUN command to Excel 2002. This command may stop working after the user updates to Service Pack 2. To the client application, the method call appears to succeed, but the macro does not run. This problem occurs if the DDE client uses an inline macro string and not a macro name in the RUN command.

Note The purpose of using an inline macro is to pass parameters to a macro.
Microsoft released a security update in June 2002 for all versions of Excel. This security update purposely blocked inline macro evaluations if the user did not have Macro Security set to Low. For additional information about the security update, click the following article number to view the article in the Microsoft Knowledge Base:
324458 MS02-031: June 19, 2002 Cumulative Patches for Microsoft Excel and Microsoft Word
Because of the security update, DDE clients that use inline macro strings with the RUN command may fail to work as expected. These clients may display an error message or may show strange behavior if they fail to run the macro.

Service Pack Information

This problem was first corrected in Office XP Service Pack 3.To resolve this problem, obtain the latest service pack for Microsoft Office XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
307841 How to obtain the latest Office XP Service Pack
After the hotfix is applied, inline macro calls that are raised by trusted clients (DDE or Automation) now run as expected if the macro that is invoked is in a workbook that has been trusted by the user through a security prompt (in Medium Security) or that has been digitally signed and previously trusted (in High Security). DDE clients that add macros dynamically or that intend to run non-trusted macros without user interaction continue to be blocked as a potential security risk to the user.

Steps to Reproduce the Problem

  1. Install Excel 2002 Service Pack 2 as directed in the following Knowledge Base article:
    307841 OFFXP: How to Obtain the Latest Office XP Service Pack
  2. Run Excel 2002, and then press ALT+F11 to open the Microsoft Visual Basic for Applications (VBA) Editor.
  3. On the Insert menu, click Module to add a new code module. Add the following code to the module:
    Sub MyMacro(s As String)  MsgBox s, vbMsgBoxSetForegroundEnd Sub
  4. Leave Excel running, and then open Microsoft Word 2002 (or another VBA host application). Press ALT+F11 to open the VBA Editor for Word.
  5. In the code window for ThisDocument, add the following code:
    Public Sub Test()   Dim chan As Long   AppActivate "Microsoft Excel"   chan = DDEInitiate(App:="Excel", Topic:="System")   DDEExecute chan, "[RUN(""'MyMacro """"Hello from DDE.""""'"")]"   DDETerminate chanEnd Sub
  6. Press F5 to run the Word macro. If you are prompted, select ThisDocument.test as the macro that you want to run. Notice that the Excel macro is never called if the Macro Security level of Excel is set to High or to Medium. No error is raised to indicate that the call failed.

    If the Macro Security level of Excel is set to Low, or if you install the hotfix that is mentioned in this article, you may receive the message that is raised by the Excel macro when it runs the DDE code.
