Solution 1

because you have not initialized the connection for the command.

Instead of this...

C#

OleDbCommand cmdd = new OleDbCommand(sql);

Do this...

C#

OleDbCommand cmdd = new OleDbCommand(sql, con);

I have already done that then it is saying
The best overload method match for 'System.Data.OleDb.OleDbCommand(string, System.Data.OleDb.OleDbConnection) has some invalid arguments

So plz give another solution

I did have a mistake. Now corrected. The spelling was wrong. Your variable is "con". I updated. Have you tried with this only?

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 2-Mar-15 4:38am

Yes, it should be...

OleDbCommand cmdd = new OleDbCommand(sql, con);

My bad. try now.
