viException: Custom Number Range

Klaus Müller

Is there a defined number range for custom viExceptions?

I want to throw a custom exception in a script and later catch that specific one. Matching by number is more reliant than matching the message, but only if the number does not clash with an existing one.

    There is no official guideline. But the exception numbers are based on the following scheme. The first 4 digits are unique to the internal product. For example. errors starting with 0810 stands for VI.DB.dll. The last 4 digits are running from 0000 to 9999 and are assigned sequentially by a tool.

    This means you should be pretty safe when using a high 4-digit number as the leading 4-digit. For example, using numbers from 99990000 to 99999999 would be a good choice.
