  Public Function Add_Employee(ByVal Employee_ID As Integer, ByVal Employee_Name_E As String, ByVal Employee_Name_A As String, ByVal Department As String, ByVal Resigned As String, ByVal Date_Of_Resignation As Date, ByVal photo As System.Drawing.Image, ByVal Birth_Day As Date, ByVal Jobtitle As String, ByVal Date_Of_Appointment As Date, ByVal Nationality As String, ByVal Bank As String, ByVal Bank_Account_Number As Integer, ByVal Bank_Branch As String, ByVal Mobile As Integer) As String
        Dim Image As New IO.MemoryStream()
        photo.Save(Image, System.Drawing.Imaging.ImageFormat.Jpeg)
        conn.ConnectionString = con
        da.Fill(ds)
        r = ds.Tables(0).NewRow
        r(0) = Employee_ID
        r(1) = Employee_Name_E
        r(2) = Employee_Name_A
        r(3) = Department
        r(4) = Resigned
        r(5) = Date_Of_Resignation
        r(6) = Image.GetBuffer
        r(7) = Birth_Day
        r(8) = Jobtitle
        r(9) = Date_Of_Appointment
        r(10) = Nationality
        r(11) = Bank
        r(12) = Bank_Account_Number
        r(13) = Bank_Branch
        r(14) = Mobile
        ds.Tables(0).Rows.Add®
        Dim CB As New SqlCommandBuilder(da)
        da.Update(ds.Tables(0))
    End Function

وهذا زر الحدث الي يستدعي function

 Dim t As New Employee_Class
            t.Add_Employee(Me.TextBox1.Text, Me.TextBox2.Text, Me.TextBox3.Text, Me.TextBox4.Text, Me.TextBox5.Text, Me.TextBox6.Text, Me.PictureBox1.Image, Me.TextBox8.Text, Me.TextBox9.Text, Me.TextBox10.Text, Me.TextBox11.Text, Me.TextBox12.Text, Me.TextBox13.Text, Me.TextBox14.Text, Me.TextBox15.Text)
