NX X NX: Problem with setting right-hand side of string expression.

When using EditWithUnits and trying to pass in a variable for a string expression you may receive a datatype error.


 Dim xyz As String = "123456"
  workPart.Expressions.EditWithUnits(expression1, nullUnit, xyz)

Solution

This will happen because NX expects to receive a string value for the input. 
Although XYZ in this case -

 Dim xyz As String = "123456"
  workPart.Expressions.EditWithUnits(expression1, nullUnit, xyz) 

 - is defined as a string, NX interprets it as an integer. To correct the issue, escape the double-quote (") character and include it in the value: 

Dim xyz As String = """123456""" \\ for VB
 workPart.Expressions.EditWithUnits(expression1, nullUnit, xyz)
