Error handling or exception method in qv

[#1]

Dear all,

Can any one please tell me how can we get a particular message that has occurred during reloading of application.

Ex: if any error comes while reloading in server it gives msg like Reload fail,

But i need to see whether is there any way so that we can get exact msg what is the problem so that the application didnt reloaded.

Please Suggest a answer.

Regards,

Pranav

There are different ways (as usual):

1. Create an alert on reading Errorvariable (e.g. SCRIPTERRORCOUNT())
2. SET ERRORMODE = 1;
   will prevent the application to stop on errors.
   at the end of the script you may add an action (create a file, do not save - exit script), if there was an error)
   if you create a file, you then may create another application reading this.
3. Read - with another application - the logfiles and inspect them for possible errors.
   Via the TRACE-command you may create out of the script further lines, as possible warnings (like unusual little amount of data found.

I prefer method 1 and 3.

1 would also inform the users that the data are probably not trustworthy.

If within the same application, you may always terminate the execution with

IF condition THEN EXIT SCRIPT; ELSE ...; END IF

Otherwise you may create a file with comment on the successful loading (or not), which then is picked up by another application - and then the above check may take place.
