Application.CompareProjectVersions method (Project)
Displays the Compare Project Versions dialog box to compare two versions of a project.
expression An expression that returns an Application object.
The CompareProjectVersions method is equivalent to the Compare Projects command in the Reports group of the Project tab on the Ribbon. If you want programmatic control of the project comparison feature (such as whether difference columns are displayed), use the CreateComparisonReport method.
The following example checks whether a project is open before calling the CompareProjectVersions method. If a project is open, the code checks whether there are either tasks or resources in the project before calling the method.
Sub CompareVersions () If Projects.Count = 0 Then MsgBox "You must have at least one project open before you can compare projects." Exit Sub ElseIf ActiveProject.Tasks.Count = 0 Then If ActiveProject.ResourceCount = 0 Then MsgBox "There are no task or resources in the current project." & vbCrLf & _ "Open a project with either tasks or resources before creating a comparison report.", _ vbInformation Exit Sub End If End If CompareProjectVersions End Sub
