Access Violation after updating to 6.5.1
Posted: 10.11.2006, 23:37
Hello.
I've been using ZeosLib 6.1.5 for more than one year and didn't want to update until the release of another stable version.
But since I always have lots of problems installing Zeos everytime I must install CBuilder, I decided to try the newest versions. I use CBuilder6 with FireBird 2.0 RC.
First I tried to install 6.6.0, with no luck at all, it doesn't even compile.
I was able to install 6.5.1 and simple tests worked, so I was happy. I created a testing version of one of my programs and imedately noted that, I don't know why, they didn't work. There was no error message, but the data wasn't being retrieved, it was like all tables were empty.
I created new Zeos components and configured their properties equal the original ones.
Some ZQueries work directly with DataAcess and Data Controls, some I just put something on their SQL property and call Open() or ExecSQL(). The Data Control ones worked fine, a DBGrid showed data again (it was empty like I said).
But (at least) one ZQuery is not working. This is the part of code with the problem:
string is a SQL string that uses Insert Into or Update depending on the case.
If the ExecSQL() is commented no error happens. If it is executed I receive this message:
The addresses are always the same...
I tried to statically link the libraries on the executable file (uncheck "Use dynamic RTL" on Linker tab and "Build with runtime packages" on Packages tab), but the access violation still happens, pointing now different addresses on the *.exe file.
It seems to be related with ZeosLib linking, since it happens when ExecSQL is called and it tries to write on a Borland code.
Anybody have idea what I can do to fix it plz?
