Hello experts,

 

My application using emulator to get fectch the result and it was shown in powerbuilder windows.

Now we have written code to decommission the existing emulator and enable new emulator.

connect to new emulator we have used OLEObject functions and new emulator dll functions.

actual issue;- Application crashes while closing.

while close the application ,Non-visual userobject functions are triggering to disconnect and clear the values from new emulator, then exit the application.

ex; uo_ex.disconnect()

      uo_ex.cleanup()

      //here piece of code to close the emulator,used emulator dll function.

      HALT CLOSE

     destory OLEObject

 

tested application working fine, but every third time application is crashing.

Please suggest ,

1. do we have any limitation on userobject size.

2. how do we know what objects consuming more memory.

 

regards

jagadeeshwar

I've seen times when applications crash if there is no RETURN after the halt close

Especially when people do a halt close from open() events.

So indeed, do the destroy before the HALT Close and just in case: put a return statement right after it.

The Destroy line will not be executed because it comes after the Halt Close. The only code executed after Halt Close is the application objects Close event.

As Chris said, try putting the Destroy before the Halt.

Hi Jagadeeshwar;

   Have you tried reversing your code?

For example:

Destory OLEObject
HALT CLOSE

HTH
