SUMMARY
This article contains two sample Microsoft Visual Basic for Applications macros (Sub procedures) that retrieve the title of a Microsoft Graph object. The second example detects if more than one Microsoft Graph object is selected. The first sample may return invalid results if more than one graph 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
