Imports Microsoft.VisualBasic Public Class UniversalThreadCode Public Shared Function TestMethod(ByVal tnMember As Integer) As String If Not UniversalThreadFunction.IsPUTM(tnMember) Then Return False End If Return True End Function End ClassIn this case, the IsPUTM() method is in UniversalThreadFunction.vb. This works well. However, it doesn't work when in non compile mode as it says UniversalThreadFunction is ambiguous. How can I resolve that?
