Hi kanuri

I suspect your sno is nothing at the initial stage, try to assign default value whne it is nothing after declaration. pls. debug and see what exactly happening..

Dim booking_no, sno As String
if isnothing(sno) then sno = 1 ' or anything u want

let me know if u need further help

Regards

This should work, add the following code

Private Function GetSno() As String

        Dim sno As String = txtProductNumber.Text

        Select Case sno.Length
            Case 1
                sno = Today.Year.ToString+ "/" + "0000" + txtProductNumber.Text
            Case 2
                sno = Today.Year.ToString+ "/" + "000" + txtProductNumber.Text
            Case 3
                sno = Today.Year.ToString+ "/" + "00" + txtProductNumber.Text
        End Select
        Return sno
    End Function

and place this function here

Dim insert As New SqlClient.SqlCommand("insert into guesthouse(booking_no,sno) values('" & GetSno() & "' ,'" & sno & "' ", conn)

Pls. mark as solved!!!
