OnErrorDefault()

Syntax

OnErrorDefault()

Changes the action taken when an error occurs back to the system default. This usually means displaying an error dialog and exiting the program, but it may also mean to just ignore certain errors. To exit the program on every error, use OnErrorExit().

Parameters

None.

Return value

None.

Remarks

When using the OnError library inside a DLL the best practice is to set the error handler at the beginning of every public DLL function and resetting it back to the default with this command before returning to the caller to make sure there is no interference between the OnError library and any exception handling done by the calling program.

Example

  Procedure ErrorHandler()
    MessageRequester("OnError test", "The following error happened: " + ErrorMessage())
  EndProcedure

  MessageRequester("OnError test", "Test start")

  OnErrorCall(@ErrorHandler())
  OnErrorDefault()         ; Comment this to get the handler call instead of the system error handling
  Pokes(10, "Hello World") ; Cause a #PB_OnError_InvalidMemory error
  
  MessageRequester("OnError test", "This should never be displayed")
