Reading File Custom Properties in VB.net

[beachcomber]

I posted this on the Solid Edge cad forum as I am having a problem with a program that edits custom file properties in Solid Edge drawing files, but haven't got an answer yet.
I am able to do all the reading and writing OK but if the property does not exist my program crashes.
I want to add in some code to check that the custom property exists and, if it doesn't, give the user the opportunity to add it.
Any ideas?

Where would we be without sat-nav?

I am well aware of this problem as well. My work around has been to error trap it or list each custom property to see if the name matches.

Example:
With seApp.ActiveDocument.Properties
For i = 1 To .Item("Custom").Count
If .Item("Custom").Item(i).Name = "MyCustomProp" Then
MsgBox "Found it!"
End If
Next
End With

In this case, the name property is case sensitive.

Hope this helps

Thanks, I think I can adapt that to do what I want.
I could use an array for the property name strings and check each custom property against that, and if the value isn't found then let the user add it.
