I have spent awhile making my first fully functional Visual Basic program. I have been kind of learning it as I go along. I have almost finished my project but I would like to have a pop up form appear when a basic if else statement is true.

This simple thing seems to be the hardest to find the answer to. I have the pop up form all made and right now it's just another form in my project...

Thanks for all the help, and feel free to laugh.:D

Webforms or Winforms?

Dim frm As New Name_of_Form

frm.Show()

I have this same question. The last suggestion on this forum doesn't seem to work. I will state the question again.

I have vb.net program with two forms, Form1 and Form2. When I start the program, only Form 1 is visable. If I add a button to Form1, what do I enter to make Form2 visible, and then how do I hide Form 2. As an example, in VB 6, I would enter Form2.show to show the form, nothing more. I would enter Form2.hide to hide the form.

What do I do in VB.net???

Thanks.

Hi Hamil

(Would you mind posting to this forum instead of e-mailing me your questions directly?? Thanks)

I think the last solution should work:

Dim frm As New Name_of_Form
frm.ShowDialog()

This creates a new instance of your form (the form's ID is Name_of_Form) and then this instance is displayed using ShowDialog().

What's the problem you're having with this solution?

First, excuse me for the email. I did not know how often you or others read this forum so I thought a direct email might get a faster response.

Dim frm As New Name_of_Form
frm.ShowDialog()

When doing the above, it seems to me that a new form is being created by the statement "Dim frm As New Name_of_Form" at run time and then displayed. I am trying to turn on a form that has been created at design time.

What I am trying to do, in most simple terms is. Assume I create a new project with two forms, Form1 and Form2. I place a button on Form1. When I run the project, only Form1 is initially displayed. So I want to add code to the button event so that when I click it, Form2 displays. I also want a button on Form2 such that when clicked would cause Form2 to hide.

Thanks.

That is correct, but that is also exactly how it is supposed to work. At design time, you describe how the form looks. That is, you actually create a class / definition of the form. When you want to display it at run-time, you'll need to create an instance of that class which you can then show.

So, the code shown earlier does what it is supposed to do: create and display a new Form2. See the design time form as a template, and the run-time form as a real form based on that template. The template by itself can do nothing, so you need to create a form out of it first.

Cheers,

Imar, or other responder. I just tried what you suggested and it doesn't work. Perhaps there is some other basic assumption I am missing.

Here is mhy bad code.



    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim frm As New Name_of_Form
        frm.ShowDialog()


'I want this button to show Form2



    End Sub

End Class



Thanks

Imar..

Thanks..

I finally got it!

I have to get over the VB 6 way of thinking.

Hamil.

And what do you think Name_of_Form is supposed to be?? It's not a special keyword, it should contain the name of your form ;)

Dim frm As New Form2
frm.ShowDialog()

Cheers,
