SYMPTOMS
When you use Visual Basic for Applications to create a new custom document Property, you may receive the following error:
CAUSE
This error is returned if the custom document property you are creating already exists.

To avoid this error, check the Custom Documents Property Collection to see if the document property already exists. The following example Visual Basic for Applications macros demonstrate how this can be accomplished.
This first macro calls the SetProp subroutine. It is a separate macro so that you can insert the single command line into a larger macro.
Sub SetCustomPropertyName()
' **************************************************
' This SubRoutine passes the Custom Property Name,
' Value and Property Type to the SetProp subroutine.
' **************************************************
' Set the custom property "MyCustomPropertyName" equal
' to "MyCustomValue". The msoPropertyTypeString constant
' specifies the type of property, and must be included.
SetProp "MyCustomPropertyName", "MyCustomValue", _
msoPropertyTypeString
End Sub
For more information about the Type property, from the Visual Basic for Applications Editor, click the Office Assistant, type Type Property, click Search, and then click to view "Type Property(Microsoft Office Reference)."
Sub SetProp(CDPName As String, CDPValue As Variant, Optional _
CDPType As Long)
' ***********************************************
' The SetProp routine checks to see if the Custom
' Document Property pre-exists. If it exits, then
' it adds the new value. If it does not exist,
' it creates the new property and adds the new value.
' ***********************************************
' Make sure the optional argument CDPType is set.
' If it is missing, make it a string value.
Dim oCDP, oProp, msg
If IsMissing(CDPType) Then
CDPType = msoPropertyTypeString
End If
Set oCDP = ActiveDocument.CustomDocumentProperties
' Compare each custom document property to the
' property you want to create to see if it exists.
For Each oProp In oCDP
' If the Custom Property exists...
If oProp.Name = CDPName Then
With oProp
' ...the custom property Type you are setting
' must match the pre-existing custom property.
If .Type <> CDPType Then
msg = "The custom property types do not match."
msg = msg + " Custom property not set."
MsgBox msg
' End the routine.
Exit Sub
End If
.LinkToContent = False
' Set the new value.
.Value = CDPValue
End With
' A match was found, so exit the routine.
Exit Sub
End If
Next oProp
' No match was found. Create a new property and value.
oCDP.Add Name:=CDPName, Value:=CDPValue, Type:=CDPType, _
LinkToContent:=False
End Sub
For more information about setting custom properties, click the Office Assistant while in the Visual Basic Editor, type CustomDocumentProperties Property, click Search, and then click to view "CustomDocumentProperties Property."
