Using ADO? Know ADO? Use friends (yahoo, google, ask, answers, bing) to search for vb6 ado tutorial...
strSQL = "SELECT [std name], [roll no], marks, category, FROM tablename WHERE [roll no] = " & Text1.Text & " AND marks >=" & somevalue
Now, if roll no is a text field you will need to do...
] '" & Text1.Text & "' AND
see the single ticks (') ? Same goes for marks but marks should be a numeric field.
Future hint for you. If you have M$ Access, you can create a dummy representative database in it to represent neary any kind of database. Fill it will some dummy data and then use the query designer to create your SQL statements. When in the designer, and you have finally figured out that you are getting the right information, you can goto view>SQL and with very little changes to that SQL statement, you can drop it right in to your program...
