Solution 1

Yes. Either:
1) Use the TextBox.Text property instead of the Textbox.ToString method.
2) Use parametrised queries and the TextBox.Text property. This way you avoid SQL Injection attacks as well, which can damage or destroy your database...

"yes dude i code like that"
Probably not.
If txtpass and txtans are TextBoxes (and I suspect they are) then ToString returns the type and the Text property. If there were strings, you wouldn't need the ToString call at all, would you? :laugh:
Try this:
cm.Parameters.AddWithValue("@u_name", txtpass.Text);
cm.Parameters.AddWithValue("@u_scl", txtans.Text);
