Well I'm back. Sorry Sinisa.

I checked my include paths. everything looks okay. Here are the details

Path for MySQL++ stuff- E:\MySQL_DEV\MySQL++\

Contains 'include', 'lib', 'mysql'

Path for MySQL stuff, I have 2 E:\MySQL_DEV\MySQL for version 3.23.42 contains the 'lib' and 'include' folder.

E:\MySQL_DEV\MySQL-4.0 for version 4.0 of MySQL contains same named 'lib' and 'include' folders.

When I want to change from linking with MySQL 3.23 libs to the new MySQL 4.0 I
just rename the above folders. In this case, 'MySQL' becomes 'MySQL_3.23' and
the 'MySQL-4.0' becomes the new 'MySQL'. This way I don't have to change any
configurations in VC++.

In VC++ I have the following definitions in Tools->Options->Directories->Include Files E:\MYSQL_DEV\MYSQL++\INCLUDE E:\MYSQL_DEV\MYSQL\INCLUDE

Tools->Options->Directories->Library Files E:\MYSQL_DEV\MYSQL++\LIB E:\MYSQL_DEV\MYSQL\LIB\DEBUG

Assumtions here: I know of nothing that needs to change under my MySQL++ folders. In other words
no changes or overlays to includes.

Any ideas???

Hello All,

I have a MSVC++ client that uses the MySQL++ client lib version 1.7.1 that has been working flawless with MySQL version 3.23.42. After reading the review I decided to upgrage to MySQL 4.0. After this I noted the compiled binary would not connect to the database. Actually this is a wrong statement. The error when debugging under MS VC 6.0 is a exception.

Assuming I needed to recompile, I swapped out the 'libMySQL.lib' and 'libMySQL.dll' and did a full recompile. I am still getting the error.

Here are the specific filenames and their sizes in case this helps.

MySQL++ libMySQL++.lib 425K 8/6/2001

MySQL files (Original 3.23.42) DEBUG Version libMySQL.dll 409K 9/15/2001 libMySQL.lib 19K 9/15/2001

MySQL files (New with 4.0) DEBUG Version libMySQL.dll 429K 2/28/2003 libMySQL.lib 24K 2/28/2003

I do not want or wish to recompile the MySQL++ Libs. I would hope if there was a dependency that someone at MySQL would provide a properly compiled version.

Any help, suggestions, directions would be appreciated.

There is no incompatibility between 3.23 and 4.0 C API, what so ever.

What happend most probably is that you use old header files with new library.
