Problem updating Access Database

[delta7]

Hi,

I'm new to C sharp and currently writing a small program that uses an Access 2003
database.

I am currently having a problem when updating a row that includes numeric data.

When updating just the text fields in the row everything works fine with the
following command:
dbCommand.CommandText = "UPDATE ScanLibTable SET Regex = '" +
txtRegex.Text.ToString () + "', Description = '" +
txtDescription.Text.ToString () + "' WHERE Key = " +
intCurrentKey.ToString () + ";" ;
but when attempting to also update a numeric field with the index value from a
drop down list I get an except because the UPDATE command is invalid:

int intLang = lstLanguage.SelectedIndex;

dbCommand.CommandText = "UPDATE ScanLibTable SET Regex = '" +
txtRegex.Text.ToString () + "', Description = '" +
txtDescription.Text.ToString () + "', Language = " +
intLang.ToString() + " WHERE Key = " + intCurrentKey.ToString () + ";" ;
Can someone point out what I'm doing wrong?

Cheers

Well, waht exception were you recieving? Is the data different between the
two? Have you tried the second sequence using literal values instead of
using all teh variables?

I can't say whats wrong without more information.

Also, FYI, you don't need all of those ToString() calls there. The text
members are already strings and the compiler will call ToString()
automatically on the integers
