URGENT!! MONO console app bug

[Patrick Kaldawy]

Some parts of this message have been removed. Learn more about Nabble's security policy.

Hello,

I have developed a console application using C# (.NET 2.0) the application connects to a mySQL database and i'm using the mySQL connector Version 6.1.2.0. I compiled the class using the following command:

gmcs Program.cs -r:mysql.data.dll -r:System.Data.dll -r:System.XML.dll -r:ResumeBuilder.PdfGenerator.

dll -r:itextsharp.dll -r:System.dll

After i ran the application on the linux server i got an error (copied below). I would appreciate it if anyone can help me figure out what's going on. Any ideas would be helpful. Thank you very much in advance.

NOTE: i have registered the MySQL connector DLL in the GAC.

If you look closely at the error (like I did, because it was in red),
then you haven't provided enough of the code that actually causes the
error.

The stack trace is pointing to:

///
 at VeechiResumeBuilder.Program.Get_User_Data () <0xffffffff>
///

Which indicates the error originated here.  Assuming you don't create
and open the connection in the Get_User_Data method, of course, can
you post a more complete example of your code?
