AV for embedded after update to 3.50

alec · Post by **alec** » Tue 01 Feb 2005 04:24

I update Mydac from 3.30.2.15 to 3.50.0.16. And now my old application raises AV for all queries to database (e.g. when I show Server Status in MyServerControl from IDE). Application rebuilding not to help me.
It's say: "Error: Access violation at address 00000000. Read of address 00000000".
I rollback to 3.30.2.15 and all works excelent without any changes in my app.
BUT: if i create NEW application with embedded server and mydac 3.50, that all works. I'm confused

I use: WinXP/2000Sp4, C++Builder 6, MySQL embedded library 4.1.9

Thanks!

Do you get this error if to execute our Embedded Demo?

Have you written correctly datadir and basedir paths in my.ini file? How have you written these paths (through "\" or "/")?

Ikar, thank you for attention!
I solve my problem.
Description:
I use MySQLMonitor in my application with mydac 3.30 and all works.
After update to 3.50 i receive AVs. Now I drop MySQLMonitor from DataModule and AV error disappear. I think, that main problem is "compatibility" MySQLMonitor 3.30 with MySQLMonitor 3.50.
After replacement of "old" MySQLMonitor by "new" MySQLMonitor all works excellent.

Do you mean TMySQLMonitor component? If so, then actions you performed mustn't tell on error occurrence. Quite possible, it will happen again.
