Calling a form from another form

[VB.NEW]

I got help from someone with my question, how do I make forms appear and disappear, but I had a few question more I was hoping I could get help with. First, I know the puporse of the last two lines of code, but what is the purpose of the first line. Second, where are the first two lines put. I mean they worked for me in the click event of a button, but can you put it in the declarations section. Last, is there a way to declare it so I can use "frm" in other controls, buttons, forms, etc, without redeclaring it.

Dim frm As Form2
frm = New Form2() ' instance a new Form2 (create an
object)
frm.Show() ' now refer to frm as an instance
of Form2

The first line of code is simply declaring the variable object for the Form instance you are going to create. You can define the scope of this variable just like any other.

If you want to use it in other procedures or events in the Form, or other module, just declare it once at the module level (top of the module outside any procedures).

I have a question that pretains to this, that code will open "Form2" but how can you make "Form1" Close but have "Form2" stay open???

I've tried
dim frm1 as new Form1
frm1.Close()

I've put that code both before, and after the code to open "Form2".

I think you're looking for the Application.Run method:

Ok, I have a completely new project with two blank forms, Form1 and Form2, There is a button on Form1, I want the button on Form1 to open Form2, Then close Form1, So after the button is pressed, the only thing open will be Form2.

Thank you guys, but I am going out of town for a week and I won't be able to try it for awhile. Just wanted to let everyone know that I wasn't ignoring your help.

Ryau: Set your application to use Sub Main as its startup object. In the module containing Sub Main, declare your global Form variables. Also declare a global ApplicationContext variable:

Option Strict On
Option Explicit On 
Imports System.Windows.Forms

Module MyApp
    Public Form2 As Form2
    Public Context As New ApplicationContext(New Form1)
    Sub Main()
        Application.Run(Context)
    End Sub
End Module

That will start your app with Form1 as its main form. Now, to switch forms in a Button_Click event, do this:

Private Sub Button_Click(ByVal sender As System.Object, _ 
    ByVal e As System.EventArgs) Handles Button.Click
    ' Create new instance of Form2
    MyApp.Form2 = New Form2
    ' Set Form2 as new MainForm
    Context.MainForm = MyApp.Form2
    ' Show it
    MyApp.Form2.Show()
    ' Dispose current form
    Me.Dispose()
End Sub

[Ryau]

Uh, I dont know what that code was supposed to do, but this is what I wanted:

code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim frm1 As New Form1
Dim frm2 As New Form2
frm2.Show()
Me.Hide()
End Sub

That opens Form2, and Hides Form1.

Ryau: If that works for you, cool. You asked, though, how to close Form1. The code you posted merely hides it; my code actually closes (or "disposes") it.
