Hi Everyone:

I have created a custom property very similar to the example in the help
section of excel. Now, I want to change its value, and I get an error. Can
someone show me how I can make the change.

To create the custom property (works fine):
ActiveSheet.CustomProperties.Add "cmb1", 125

To change the value ( I get the error):
ActiveSheet.CustomProperties.items(1).Value = 2000

So, for the CustomProperty named "cmb1", I want to change the value from 125
to 2000. Thanks for all your help.

Bob

Bob,

I've found CustomProperties to be a bit flakey, especially when trying
to access a property by name. I use a function called IndexOfProperty
that returns the numerical index into CustomProperties of the
specifiied property name. For example,

Dim N As Long
Dim S As String
N=IndexOfProperty(Worksheets("Sheet1"),"PropName")
With Worksheets("Sheet1").CustomProperties
If N<>0 Then
S=.Item(N).Value
MsgBox "Property 'PropName' has a value of " & Cstr(S)
Else
Msgbox "Property 'PropName' not foundl."
End If
End With

The complete IndexOfProperty is show below:

Function IndexOfProperty(WS As Worksheet, PropertyName As String) As
Long
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' IndexOfProperty
' Returns the 1-based index number corresponding to a CustomProperty
' of worksheet WS with a property name equal to PropertyName. Returns
' 0 if property name was not found.
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Dim N As Long
With WS.CustomProperties
For N = 1 To .Count
If StrComp(.Item(N).Name, PropertyName, vbTextCompare) = 0
Then
IndexOfProperty = N
Exit Function
End If
Next N
End With
IndexOfProperty = 0 ' not found

End Function

The following coide illustrates deleting, creating, modifying, and
retrieving a CustomProperty:

Sub AAA()

Dim WS As Worksheet
Dim Props As Object
Dim PropName As String
Dim PropValue As Variant
Dim N As Long

Set WS = ActiveSheet
' delete property. ignore error if it doesn't exist.
On Error Resume Next
N = IndexOfProperty(WS, "TheProp")
If N <> 0 Then
WS.CustomProperties(N).Delete
End If
On Error GoTo 0

' add a new property with a value
WS.CustomProperties.Add Name:="TheProp", Value:=12345

' change the property value
N = IndexOfProperty(WS, "TheProp")
If N <> 0 Then
WS.CustomProperties(N).Value = 1357
End If


' retrieve the property
PropName = "TheProp"
PropValue = WS.CustomProperties(N).Value
Debug.Print PropValue
End Sub
