Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

    Try
        Dim s As Boolean
        If rdbMale.Checked = True Then
            s = True
        ElseIf rdbFemale.Checked = True Then
            s = False
        End If

        Dim fsreader As New FileStream(OpenFileDialog1.FileName, FileMode.Open, FileAccess.Read)
        Dim breader As New BinaryReader(fsreader)
        Dim imgbuffer(fsreader.Length) As Byte
        breader.Read(imgbuffer, 0, fsreader.Length)
        fsreader.Close()
        strsql = "insert into students (Stdnt_ID, Fname, Lname, Mname, Gender, Dob, Depart, Crse, Major, Sec, Address, Contact_Number, StudentPic) values (@dtaID, @dtaFname, @dtaLname, @dtaMname, @dtaGend, @dtaDob, @dtaDepart, @dtaCrse, @dtaMajor, @dtaSec,@dtaAddress, @dtaCont, @dtafile)"
        cmd.CommandText = strsql
        cmd.Connection = (OleCn)
        cmd.Parameters.AddWithValue("@dtaID", IDtxts.Text)
        cmd.Parameters.AddWithValue("@dtaFname", nmetxt.Text)
        cmd.Parameters.AddWithValue("@dtaLname", lastxt.Text)
        cmd.Parameters.AddWithValue("@dtaMname", mitxt.Text)
