Was someone successful to run TLCV with Arena (1.03)? I only see the names of the programs and the PV. Any Hints?
Regards

G'day Volker,
The Arena developers still have not modified the way Arena accesses the debug file. TLCV opens the debug file in read write shared mode, while Arena opens the file in read shared mode, which is not 100% compatible. This means that Arena will occasionally fail to write a line to the debug file. TLCV opens and closes the file frequently, which is why most lines are written to the debug file successfully and only a small percentage is not. I'm not sure when or if the Arena developers are going to change the way Arena accesses the debug file, in fact I have given up hope. Arena is written in Delfi so I looked up the commands that Delfi uses to open files and I found the file mode that will be compatible with TLCV and then I posted this information on Arena support forum. Several versions of Arena have since been released and nothing has changed with the way Arena accesses the Debug file. I could be wrong, but I don't think it is a big job for Arena programmers to change the open file mode.
Cheers,
Tom.

I am not sure if Delphi does what I want. I have modified my code twice and at the moment I doubt that Delphi can do the shared mode writing at all. I will look at it again.

G'day Martin,
Thanks for your feed back. Have you tried 'fmShareDenyNone' open file mode? I have only tested Arena as far as v1.03. Should I test the latest versions of Arena too?
Cheers,
Tom.
