Once I run the program it give me this error:
An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll

Here is the code:
OleDbConnection Conn=new OleDbConnection(ConnString);
Conn.Open();
OleDbDataReader dr;
OleDbCommand dbcom=new OleDbCommand();
DataSet ds=new DataSet();
OleDbDataAdapter da=new OleDbDataAdapter();
da.SelectCommand=new OleDbCommand(Sqlstring,Conn);
da.Fill(ds);
dbcom.Connection=(Conn);
dbcom.CommandText=Sqlstring;
dr=dbcom.ExecuteReader();

it say the dbcom is undefined value.

It looks like you have an error in the SQL query probably.

[lieweffect]

So,what should I do and how to fix it.
Thank Q

[shabbir]

By correcting the errors in the query.

[lieweffect]

May I know how to correct it please?

[shabbir]

If you can share the query we can definitely look into it.

Here is the whole program code

[shabbir]

Please dont attach the complete projects as its very difficult to find where the error is and where the query is. I have removed the attached project.

Please read Before you make a query.

[lieweffect]

Sorry, because I don't know how to find the query as you know I'm the beginner of programming.If I did something please correct me!

Whats the value of Sqlstring when its giving the exception.
