To help you debug your script in Modeler, you can use message boxes (MsgBox "<text>"), or send messages to the Modeler output pane (DisplayOutputWindowMessage "<text>").
If you want to perform more advanced debugging, you can add your script to a Visual Basic component and debug the script using the Visual Basic facilities.
If you want a Visual Basic or C# application to work with Modeler on a 64-bit Windows operating system, you must build the application to run as a 32-bit application. To do this, set the Target CPU up as X86 on the Advanced Compilation dialog.
