I'm creating a dll for looping through all the tables in a certain directory and performing some maintanence operations. Sometimes errors occur that I need to process. I tried the following:

DEFINE CLASS myClass

PROCEDURE MyErrorHandler
RETURN
ENDPROC

PROCEDURE MyMethod
ON ERROR DO THIS.MyErrorHandler
*-- statements
RETURN
ENDPROC

ENDDEFINE

but the enviroment says it 'cant find this.myerrorhandler.prg'. What would be the correct syntax for calling an error handler here?
