SUMMARY
This article contains two sample Microsoft Visual Basic for Applications macros (Sub procedures) that retrieve the title of a Microsoft Graph version 8.0 object. The second example detects whether more than one Microsoft Graph version 8.0 object is selected.

Example 1
Sub GetGraphTitle

' Used for error trapping. On Error Resume Next

' Clear the error object. Err.Clear

' A reference to an object. Dim oGraph As Object

' Check if an OLE object is selected. Set oGraph = ActiveWindow.Selection.ShapeRange(1).OLEFormat.Object If Err.Number <> 0 Then

' A run-time error is generated if the selection is not an OLE ' object. This code traps the run-time error and prevents it from ' appearing. MsgBox "Select one graph and run the macro again.", vbExclamation End End If

' Check to see whether the graph has a title. If oGraph.HasTitle Then

' A run-time error is generated if the selection if not a     ' Graph object. This code traps the run-time error and prevents it     ' from appearing. If Err.Number <> 0 Then MsgBox "Select one graph and run the macro again.", vbExclamation End End If

' The graph has a title. MsgBox oGraph.ChartTitle.Text, vbInformation, "Graph Title" Else

' The graph does not have a title. MsgBox "The selected graph has no title.", vbInformation, "No Title" End If

End Sub

Example 2
Sub GetGraphTitle

' Declare the variables. Dim strErrorPrompt As String Dim strErrorTitle As String Dim shapeGraph As Shape Dim oGraph As Object

' Check to see whether the selection is a shape. If ActiveWindow.Selection.Type <> ppSelectionShapes Then

' The selection is not a shape. ' Set up the message box. strErrorPrompt = "The selection is not a graph." _        & " Please select a graph and run the macro again." strErrorTitle = "No Graph Selected"

' Display the message. MsgBox strErrorPrompt, vbExclamation, strErrorTitle

' Stop the macro. End End If

' Check to see whether more than one object is selected. If ActiveWindow.Selection.ShapeRange.Count > 1 Then

' Set up the message box. strErrorPrompt = "More than one object is selected." _        & " Please select one graph and run the macro again." strErrorTitle = "Too Many Objects Selected."

' Display the message box. MsgBox strErrorPrompt, vbExclamation, strErrorTitle

' Stop the macro. End End If

' Check to see whether the selection is an OLE object. Set shapeGraph = ActiveWindow.Selection.ShapeRange(1) If shapeGraph.Type <> msoEmbeddedOLEObject Then

' The selection is not a graph. strErrorPrompt = "The selection is not a graph." _     & " Please select a graph and run the macro again." strErrorTitle = "No Graph Selected."

' Display the message. MsgBox strErrorPrompt, vbExclamation, strErrorTitle

' Stop the macro. End

End If

' Check to see whether the selection is a graph object. If shapeGraph.OLEFormat.ProgID <> "MSGraph.Chart.8" Then

' The selection is not a graph. strErrorPrompt = "The selection is not a graph." _     & " Please select a graph and run the macro again." strErrorTitle = "No Graph Selected"

' Display the message. MsgBox strErrorPrompt, vbExclamation, strErrorTitle

' Stop the macro. End

End If

' A graph is selected. Set oGraph = shapeGraph.OLEFormat.Object

If oGraph.HasTitle Then

' Get the title and display a message box. MsgBox oGraph.ChartTitle.Text, vbInformation, "Graph Title"

Else ' The graph has no title. MsgBox "The selected graph has no title.", vbInformation, "No Title"

End If

End Sub
