First, use parameterized queries to execute your SQL statement, not this string concatenation you're using. Why? You have a problem that is EASILY avoided by doing do.

This is what you're query currently looks like:

select * from Di1 Where Word LIKE'somevalue'%

You're missing a space after LIKE and the '%' character needs to be INSIDE the single quote marks, not outside of it.

Your code should be like this:

VB

cmd = New SqlCommand("select * from Di1 Where Word LIKE" & "'" & TextBox7.Text & "%'",cn)
        adp = New SqlDataAdapter(cmd)
        adp.Fill(ds, "Di1")
        DataGridView1.DataSource = ds.Tables("Di1")

your upper query is correct but in the 2nd piece of code you have 's'% instead of 's%'.

'%' includes within single qoute.
