Document.MacrosEnabled Property

  • Article
Visio Automation Reference

Specifies whether you can execute macros and process events in a document's Microsoft Visual Basic for Applications (VBA) project. Read-only.

Version Information
 Version Added:  Visio 2002

Syntax

expression.MacrosEnabled

expression   A variable that represents a Document object.

Return Value
Boolean

Remarks

If your document contains macros that are necessary to your solution's execution, you can use the MacrosEnabled property to verify whether macros are enabled in the document. If they are disabled, you can display a message indicating that your solution may not work as expected because document settings prohibit macros from being executed.

The value of the MacrosEnabled property depends on a combination of the macro setting and the project's signature status (whether it is digitally signed by a trusted source or in a trusted location). The following table describes these combinations.

By default, macros are disabled in a Visio document not from a trusted publisher, or that is not digitally signed, or that is not in a trusted location.

However, you can change default settings in the Macro Settings category of the Visio Trust Center (Tools menu). If Disable all macros except digitally signed macros is selected, macros in Visio documents not in a trusted location are enabled only if the documents are digitally signed. If you select Disable all macros without notification or Disable all macros with notification, macros in documents not in a trusted location are disabled. If you select Enable all macros, all macros are always enabled, but this option presents a security risk and is not recommended.

Trusted sources are listed in the Trusted Publishers category in the Trust Center, and trusted locations are listed in the Trusted Locations category.

To open a document in a disabled state (macros are not enabled), you can use the OpenEx method of the Document object. For example:

Visual Basic for Applications 
  Documents.OpenEx(fileName, visOpenMacrosDisabled)

Example

The following example shows how use to open a document from an add-on and use the MacrosEnabled property to determine whether macros are enabled. If macros are disabled, a message box appears warning the user of limited functionality. Before running this example, supply a valid document file name for the variable filename.
