During development errorsTrapping is usually set to “Unhandled Error Interrupt” and an error is raised in each case.class module, the debugger stops directly at the line that extremely calls the class, likeline of attack in the general class. This discovery makes solving the problem very painful.

We recommend using “Interrupt Class Units”, this also stopsthe actual drop in the queue. Note, however, that this will not work if you haveUse Help to increase errors in your classes with the Err.Raise command. This orderactually raises an “error” and executes your procedure when error trapping might stopset to “interrupt in class modules”.

Sorryyu, members can change this setting for nowWhen starting the application, make sure this option is set correctly every time you start the application.

Option functions can be viewed and edited programmatically using the Application.GetOption and Application.SetOption methods.
