Hi All,

I posted the below in the Visual Basic forum and was advised to post it here as well. Hope you can help.

I am very new to VB.net and need a little help. I currently have a calculator to calculate the number of days between two days.

What i need now is something that will calculate working days between two dates (Mon-Fri being the workdays)

(See Below)

Code:
Public Class GMPF_Calculator


    Dim d1 As Date
    Dim d2 As Date
    Dim days As Double



    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        '============Date fields Start============

        d1 = TextBox1.Text
        d2 = TextBox2.Text

        If d1 > d2 Then
            MessageBox.Show("Start Date is greater than End Date", "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning)
            Exit Sub
        End If


        days = DateDiff(DateInterval.Day, d1, d2) + 1
        TextBox4.Text = days
Thanks in advance
