Zeoslib Portal

Hello! I have installed D2009 and Zeoslib_trunk_558. It is all ok with Firebird 1.5.5 and mysql. But I can't connect to mssql Server 2005.
At Delphi 11 with ZeosLib361 works well.

I hade the same problem as you and fixed it by changing some files.
If you like I can mail you my changed source code.

Don't mail. Please, attach a diff or the changed files in the forum. I don't have mssql so I can't test it myself.

O.K. here my changed files.
It works on windows 7 with delphi 2010.

Hi,

Thanks for the files, but I'm wondering why you had to change the component layer and the general dbc classes when the problem only occurs with mssql. As it worked before with FB and mysql we sholdn't changes their behaviour.
Isn't it sufficient to replace the ZDbcDblib* files?

Mark

Hi,

I can confirm that only replacing the ZDbcDblib* files fixes the connect error with M$ SQL Server.
Testet with Delphi 2009 (Update 3) under Wnidows 7 on SQL Server Express 2008, hope this answers your question.

Also thx. for a great DB component.

Thanks for the test, Dunnys.
