Forms Talking to each other?

[w8taminute]

Hello everyone,

I am trying to get one of my forms (frm1) to show another form (frm2) and then wait until the a button is clicked in frm2 to continue with the following code in frm1.
Here is an example:


Dim var1 as Integer
Dim frm2 As New frm2
frm2.Show()
var1 = var2

I want to pass the value of var2 to var1 when I click a button. var2 comes from frm2. What is happens instead is,frm1 shows frm2 and continues on to the next line (var1=var2). Can anyone help?

Try the ShowDialog method
e.g.

frm2.ShowDialog

That is a blocking call

Use ShowDialog so it stops processing on the first form until the second is closed.

Dim var1 as Integer
Dim frm2 As New frm2
frm2.ShowDialog()
var1 = var2

Remove var1 = var2 from the Form Load.

Presuming both are declared on Form1, make them Public variables. Then in your button on Form2, just do

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form1.var1 = Form1.var2
    End Sub

If var2 is declared on Form2, then remove the Form1 prefix from var2.

Thank you all for your help. I used showdialog() and that's exactly what I was looking for.
