Hello DBISAM team.

I recently got working my trial version of 4.22 with success.

Now I have a strange behaviour. I load a dll which opens a remote database connection. Everything is fine, except when I close my app, I call FreeLibrary
(dllhandle), and the program freezes.

I have isolate the problem. I have a line which opens the connection:

DataModule1->DBISAMDatabase1->Connected = true;

When this line is uncommented, the FreeLibrary hangs the execution. When I comment this line, the program closes normally.

So I guess some resource is kept inside this dll when unloaded. I have tried to disconnect the database component when the Dll is detached. No success.

How should I close a session correctly? Maybe I am leaving something inside the dll?

Please any ideas will be welcomed. Once again, thanks for the support.

I have added a new statement when dll is detached.

DataModule1->DBISAMSession1->Close();

The program freezes at this point. Any clue?

Jack,

Are you trying to reference any DBISAM components in the DLL directly from
the application ?  If so, then do not do this.  The DLL and EXE use
completely separate class information, virtual method tables, etc. and you
cannot mix the two.  If you want to do this, then you need to use a runtime
package instead.

If you aren't mixing the two, then if you could post the source to the DLL,
it would help immensely.

Thanks,
