help accessing control from a different form

Dec 18th, 2008

Hello everyone. I have been studying VB on my own in prep for my class next semester. I am trying to update a label on form1 from form2. Below is just a "test" example i created to figure out what im doing wrong. It is not the actual project i am working on.

this is the form1 code

 Help with Code Tags 
 vb Syntax (Toggle Plain Text) 
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        Dim frm2 As New Form2()
 
        frm2.Show()
 
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim frm2 As New Form2()

        frm2.Show()

    End Sub

this is the second form code. am i accessing this wrong or declaring something else incorrectly? If you need anymore info,let me know. All i have is one button on the first form opening the second form. This form has a button that when i click it, i want to update the label in form1. Thanks you in advance.

Well, it depends. Are you destroying Form1 when you go to Form2? If you are then you are right. I feel though that you are not, so, what you have is Form1 and Form2 and then creating frm1.

Delete the line:
Dim frm1 As New Form1()
and change the next line to:
Form1.lblTest.Text = "Hello"

If you are using vb 2005 or vb 2008 then you don't need to create a new form. Just use:

Form2.Show()

It is hard to understand how a cemetery can raise its burial rates and blame it on the cost of living.
