I use VB 2008 Express Edition, and I cannot get my multiple form application to work correctly. I am trying to get frmNext to show up after frmInput is done. So, in frmInput's button click event, I type in strName = TextBox1.Text, frmNext.Show(), and Unload frmInput. Unload does not work in vb 2008 anymore I guess, because it gave me an error. So, I typed in Me.Close(), which closes the application altogether. So, I decided to go into frmNext's form load event and type in Me.Text = strName and frmInput.Close(), which causes the entire program to close. I need help getting frmNext to show up and frmInput to close down.
Ah im not that great yet but could you post the whole code? I could probly help ive been using it for a few years now.
Option Explicit On Module Module1 Public strName As String End Module Option Explicit On Public Class frmInput Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click strName = TextBox1.Text frmNext.Show() Me.Close() End Sub End Class Option Explicit On Public Class frmNext Private Sub frmNext_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Text = strName End Sub End Class
Create a module with a Sub "Main" Code: Imports System.Windows.Forms Module Module1 Sub Main() Dim frmInput as new FormInput frmInput.Show() Application.Run() // This starts the App without a start-up main form End Sub End Module In the Input Form (which will load as the default form) Code: Private closeApp as Boolean = True Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) handles Button1.Click closeApp = False; Dim nextFrm As New NextForm nextFrm.Show() Me.Close() End Sub // Just in case you want to kill the App from this form Private Sub InputForm_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing If closeApp Then Application.Exit() End If End Sub In Next Form, use something like this to close the Application Code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Application.Exit() End Sub This is not the most robust way of doing this, but it should work for you.
Whenever I wanted to do something like that back in the day, i'd simply change the visibility of the form frm.setVisible(true); to display it frm.setVisible(false); to hide it
That works okay, but then you have unneeded components and their associated resources hanging around eating up stack and heap space (RAM). It is better to dispose of the unneeded resource so that the garbage collector can clean up after you.
After some quick perusing ... You may just be able to go into your projects properties page, and under the Application tab set the "Shutdown mode" to "After last form closes" instead of the default "When main form closes".
