XL2002: DDE Clients Cannot Use a RUN Command to Run an Inline Macro After a Security Update
Article ID: 821136 - View products that this article applies to.
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:
324458Because 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 InformationThis 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:
307841After 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.
