clear function

[stuart1512]

im learning VB.Net


i have a program with checkboxes in a form. i have a button that outputs a message box with the choices i have ticked on the checkboxes. the button shows the ones i select but also the previous ones. i have another button "clear" but i dont know how to remove the selections from the messagebox

here is my code

Public Class Form1

Dim Message As String
Dim Counter As Integer = 0

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If CheckBox1.CheckState = 1 Then
Message = Message & CheckBox1.Text & vbNewLine
Counter = Counter + 1
End If
If CheckBox2.CheckState = 1 Then
Message = Message & CheckBox2.Text & vbNewLine
Counter = Counter + 1
End If
If CheckBox3.CheckState = 1 Then
Message = Message & CheckBox3.Text & vbNewLine
Counter = Counter + 1
End If
If CheckBox4.CheckState = 1 Then
Message = Message & CheckBox4.Text & vbNewLine
Counter = Counter + 1
End If
If CheckBox5.CheckState = 1 Then
Message = Message & CheckBox5.Text & vbNewLine
Counter = Counter + 1
End If
MsgBox("You have chosen" & vbNewLine & Message)
MsgBox("Counter = " & Counter)
End Sub


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

End Sub
End Class


thanks in advance

Hm, if I understand you correctly, all you have to do is set your message-string to nothing and your counter to zero.

Just put something like this in your Button2.Click-event:

Message = Nothing
Counter = 0

I would have thought it would just be:

Message = String.Empty

Try Checkbox.Checked and not CheckState ?

I'm new to VB too and I am guessing you were working through the tutorial here http://www.homeandlearn.co.uk/net/nets4p14.html

I also was stuck there but solved it after reading this thread (thanks to Chris128 mostly). Anyway below is what I did to finally achieve what the tutorial was asking

Public Class Form1
Dim message As String
Dim counter As Integer = 0

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

If CheckBox1.CheckState = 1 Then
message = message & CheckBox1.Text & vbNewLine
counter = counter + 1
End If
If CheckBox2.CheckState = 1 Then
message = message & CheckBox2.Text & vbNewLine
counter = counter + 1
End If
If CheckBox3.CheckState = 1 Then
message = message & CheckBox3.Text & vbNewLine
counter = counter + 1
End If
MsgBox("You have chosen " & vbNewLine & message)
MsgBox("You have chosen " & counter & " soaps")
message = String.Empty

Select Case counter
Case 0
MsgBox("not eating")
Case 1
MsgBox("not that hungry")
Case 2
MsgBox("pig")
Case 3
MsgBox("very piggy")

End Select
counter = 0

End Sub
End Class
