Antonio,

In the begin of this post I have included the content of HB_OUT.log.
IF I comment HB_GCALL( ) on method End() of dialog.prg everything works fine.

have you considered to create an external EXE using your PRG code and call it for each document ?

That way the memory of your app and the memory used by such OCX will not conflict.

I see it is a private OCX, have you contacted its developers for help ?

No, because I have to interact with the ocx created, add files, doing merge, etc

I see it is a private OCX, have you contacted its developers for help ?
Yes it was the first thing I did, but they told that don't have this kind of problem with any other language !

Important - I use this OCX since when I was working with FW/Clipper(different version of course). WIth Harbour I come using it since 2014 without problems. The problem has start from FWH1707.

I'm sorry I know this post is from 2018 but I have a similar problem. I use an OCX from Topaz to gather patient signatures on documents. The line hb_gcAll() inside Tdialog breaks the program after a few times being executed.

Has a solution to this been found?

Thank you.

Dear Reinaldo,

do you get a hb_out.log file ?

If so, please post it here, thanks

Possibly tonight after users are gone, I can access the PCs that have this problem which are the ones using a Topaz signature pad. But I can tell you the top line on the call list looks like this:

Called from HB_GCALL(0)
Called from TDIALOG:END(555) in .\source\classes\DIALOG.PRG


That's how I know the problem is at hb_gcAll(). But this is only happening on the PCs with the Topaz Signature pad. All other PCs running the very same .exe work fine. The only difference is the application on those other PCs never calls any Topaz OCX methods.

For now I commented that line and I'm linking dialog.prg to override that line.

But I know that others in the fwh community are using Topaz signature pads. Are they also commenting this line?

Realmente el problema es muy antiguo.
Otras veces ha ocurrido con CodeJock

https://www.forums.fivetechsupport.com/ ... 15#p145103

Pareciera que hay un problema con determinado tratamiento de determinados objetos OLE

Lo que yo haria seria intentar poner a NIL manualmente y antes de que se cierre el dialogo de la manera concreta posible todos los objetos OLE utilizados

Es buena sugerencia. Puedo ver como eso debiera funcionar.

Gracias.
