string qry1 = "update log_in set password='" + txtnew.Text.Trim() + "' where userid='" + txtuser.Text + "'";
cmd = new OleDbCommand(qry1, con);
cmd.ExecuteNonQuery();
MessageBox.Show("Password changes Sucessfully");

the error is "Syntax error in UPDATE statement."

password is a reserved field name.

Try changing your code to read:

string qry1 = "update log_in set [password]='" + txtnew.Text.Trim() + "' where userid='" + txtuser.Text + "'";

Consider using an application configuration file to store your database path / connectionstring.

take a look at one of my other replies:

Hope this helps Smile | :)

Thanks for your suggestion

I have used app.config file to store connection string for rest of my application but i am unable to create cyrstal report using that string.

Because when I create crystal report i need to use database field from field explorer which are present only when i establish connection at creation time of crystal report.

Is there any other way to generate crystal report so that i can use app.config connection string for that.

Try something like this:

foreach ([forgot object name] tbl in CRReport.Database.Tables)
{
   tbl.SetLogOnInfo("",dbLocation,dbUser,dbPass)
   tbl.Location = dbLocation
   tbl.SetDataSource(dbLocation)
}

I've not got CR installed here, so can't double check the function and object names,
but I believe that will redirect your database source for you Smile | :)

The first parameter of "SetLogOnInfo" i think is a connection string, but I don't think you need this when reading from Access.. I've only ever used SQL Server, so I will say this is all just guess work WTF | :WTF:

Anyways, hope it works for you! Cool | :cool:

If you let me use your application, I can erase your entire database. Try reading up on SQL injection attacks.
