Question

Hi Friends,

I am calling from Form1 from  Main Form and then from Form2 from Form1 I want to change texttbox1 (Form1) value from 

Form2 without recalling the new form of Form1 , I not could pass value code as below

 

Main Form code

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

 Dim f1 As New Form1
        f1.TextBox1.Text = "From Form1"
        f1.TextBox2.Text = "From Form1"
        f1.ShowDialog()

 End Sub

Form1 Code as below

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f2 As New Form2
        f2.TextBox1.Text = "From Form2"
        f2.TextBox2.Text = "From Form2"
        f2.ShowDialog()
    End Sub

FORM3 CODE 

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        
        Form1.TextBox1.Text = "from form2"
        Form1.TextBox2.Text = "from form2"

    End Sub

Code in form3 not working and value not changing  unless I will call new instance of Form1, I want without calling

new instance of Form1 the value will be change.

Answer 1

Try two modifications:

   Dim f1 = Form1

and

   Dim f2 = Form2

Answer 2

What does not working mean?

I'm pretty sure it works. But did you call Show() for Form1 somewhere?
