i hope someone can solve this problem

thank you.

:D dude dont u use functions the project to the need to simplify with func. but then some1 reads the this long codes without getting bored and they can help u. but just w8 ill trying to understand 156line :D

i think u r new in software world :)

i give up its really very complex.As I said a little while ago u need to simplify this project with using functions
in my style i dont write same thinks again. if i notice i write same thinks then i ll write a function i use this .

for example

If Date.Now.DayOfWeek.ToString = "Monday" Then
            TextBox3.Text = pay.ToString("0.00")
            ListBox1.Items.Add("Charge: " & pay.ToString("0.00"))
        ElseIf Date.Now.DayOfWeek.ToString = "Tuesday" Then
            TextBox3.Text = pay.ToString("0.00")
            ListBox1.Items.Add("Charge: " & pay.ToString("0.00"))
        ElseIf Date.Now.DayOfWeek.ToString = "Wednesday" Then
            TextBox3.Text = pay.ToString("0.00")
            ListBox1.Items.Add("Charge: " & pay.ToString("0.00"))
        ElseIf Date.Now.DayOfWeek.ToString = "Thursday" Then
            TextBox3.Text = pay.ToString("0.00")
            ListBox1.Items.Add("Charge: " & pay.ToString("0.00"))
        ElseIf Date.Now.DayOfWeek.ToString = "Friday" Then
            TextBox3.Text = bayar.ToString("0.00")
            ListBox1.Items.Add("Charge: " & bayar.ToString("0.00"))

this lines
u need to build func like

private sub example(byval dayofweek as string ,byval TB as Textbox,byval LB as Listbox,byval py as double)

  TB.Text = pay.ToString("0.00")
    LB.Items.Add("Charge: " & py.ToString("0.00"))
end sub

   Private Sub btnlimaringgit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnlimaringgit.Click
example(Date.Now.DayOfWeek.ToString,Textbox1,listbox1,pay)
example(Date.Now.DayOfWeek.ToString,Textbox2,listbox1,pay)
.
.
.

end sub

State the actual error you receive or observe and try some code simplification by breaking them down. That way, you can be more efficient in debugging your own codes
