I am trying to connect to a mysql database with a wrong password using Connector/Net.
The returned MySqlException.Number equals to 1045,
which doesnt match any member of the MysqlErrorCode enumeration.

The MySQL server version is a 5.0.32-7etch5, running on 
Linux Debian 2.6.18-6-486

How to repeat:
cnnConnection.ConnectionString = "Server=myserver;User id='invaliduser';Password='invalidpassword';Database=mybase"
            catch (MySqlException ex)
                string message="";
                switch ((MySqlErrorCode)ex.Number)

Hi Sylvain and thanks for your report.

I can not repeat it since ERROR 1045 *is* defined in latest sources I use:
MySQLError.cs, ln: 129
            UnableToConnectToHost = 1042,
/*                ER_HANDSHAKE_ERROR 1043
                ER_DBACCESS_DENIED_ERROR 1044
                ER_ACCESS_DENIED_ERROR 1045
                ER_NO_DB_ERROR 1046

which exactly matches server's error both in ErrCode and in error text:
C:\mysql-5-0-64-pb1103-win32\bin>mysql -uroot -p -P5064 test
Enter password: ********
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: Y

Test case:
    MySqlConnection conn = new MySqlConnection();
    conn.ConnectionString = "DataSource=localhost;Database=test;UserID=root;Password=tupello;PORT=5064;Allow Zero Datetime=True;logging=True;";
    catch (MySqlException ex)
        Assert.AreEqual(1045, ex.Number);

Hi Tonci,

Your snippet shows that
is defined but still into comments and not known from the enum.

Your test case also uses the literal value and not a enum constant.

Sylvain, thanks for pointing out to me the error in thinking. True, verified just as described by looking into code for MySqlErrorCode.
Workaround is simple and obvious, we need to add 1045 there.

Fixed in 5.1.7 and higher

Just a quick check. Looking at the patch, the fix appears to have gone into 5.1.6 (or I may have misinterpreted the patch). Should this change appear in the 5.1.6 or 5.1.7 changelog? Thanks!
