Change form from another form.

[WelshyWizard]

Hi all,

I've got 2 forms, Form1 and Form2.
Pressing a button on Form1 sets Form1.enabled = False and also opens Form2. Pressing a button on Form2 should set Form1.Enabled = True and close itself. Although Form2 does close, Form1 remains disabled.

My code for enabling Form1 is as follows:

    Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click

        Dim M1 As New Form1

        M1.Enabled = True

        Me.Close()

    End Sub

Does anyone have any tips on how to get this to work and what I'm doing wrong?

Cheers

I think your problem lies in this line:

Dim M1 As New Form1

You already have Form1 open with some name...you don't need to create a new instance of the form.

So your code above should be something like:

Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click

        Dim M1 As New Form1

        Form1.Enabled = True
        'if you created an instance using Dim something As Form1 before opening Form1 then replace the Form1 above with something

        Me.Close()

    End Sub

Basically, each time you use the New directive, a new INSTANCE of the form is being opened. So you are never reenabling the Form1 you originally started with.

Oops...clicked Submit too fast...code should be:

Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click

        Form1.Enabled = True
        'if you created an instance using Dim something As Form1 before opening Form1 then replace the Form1 above with something

        Me.Close()

    End Sub

get rid of this line
Dim M1 As New Form1

and change this line
from M1.Enabled = True to Form1.Enabled = True

Thanks guys,

I tried this first time around and for some reason, when I type this in I get the ominous squiggly blue line under Main1.Enabled. When I hover over this the tooltip tells me 'Reference to a non-shared member requires an object refernce'. Any ideas?

Cheers

There are a number of FAQs on this forum covering interaction between Forms.


Hope this helps.
