Sub Main () [Resolved]

This is in part two of my other post for an opinion on using a panel for a splash screen. I opted to not use the panel but I tried adding a Form2 to use instead.

Form1 is my main program, I have added a Form2 and placed this code below in it. I have changed the startup object to Form2 and I can get it to load before Form1 correctly so I can use Form2 as my splash screen.

Code:

---

Public Class Form2
    Inherits System.Windows.Forms.Form

+ Windows Form Designer Generated Code

<STAThread()> Shared Sub Main()

       
        Dim frm1 As Form1

     
        frm1 = New Form1()

     
        Application.Run(frm1)

    End Sub

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

    Me.Close

   
    End Sub

---

My trouble is that when I push the button on Form2 to close it and show Form1 "My main program" it closes the Form2 but doesn't bring up my Form1 "main program" as it should.

Any other thoughts on what's wrong? Knowing me it's something simple or just my lack of knowledge.

P. S. Pirate, I liked your splash screen but for some reason it didn't work when I tried to impliment it with my program.

hi...try this one
in your form1 constructor

VB Code:

Dim f As Form
    Public Sub New(ByVal f As Form2)
        MyBase.New()
 
        'This call is required by the Windows Form Designer.
        InitializeComponent()
        Me.f = f
        'Add any initialization after the InitializeComponent() call
 
    End Sub
'in the form1load
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        f.Close()
    End Sub

make this as startup object

VB Code:

Module Module1
    Sub main()
        Dim x As New Form2()
        x.Show()
        Application.Run()
    End Sub
End Module

in your form2

VB Code:

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

hope it helps...

This a way, very easy, but your Form2 (the splash) is not destroyed when you click its button. It's only hidden:

Code:

---

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f1 As New Form1
        Me.Hide()
        f1.ShowDialog()
        Me.Close()
    End Sub

---

But the right way is this, I think:

Code:

---

Module Module1
    Sub Main()
        Dim F2 As New Form2
        Dim F1 As New Form1

        Application.Run(F2)
        Application.Run(F1)
        End
    End Sub
End Module

---

To use the second one you have to set the startup object to sub main, then add a module to project (default name should be Module1 as mine), and then add the sub main to it, exactly it's showed in the example. In this way, when you will close F2 (with Me.close, for example, or with the X in the high-right corner), F1 will be displayed

Good job:)

i do this

VB Code:

'form1 as startup object
   Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
      Dim f As New Form2()
      f.ShowDialog()
   End Sub
 
'form2 has opacity 0
'set timer1.enabled = true
  Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
      Me.Opacity += 0.01
      If Me.Opacity = 1 Then
         Timer1.Stop()
         Timer2.Start()
      End If
   End Sub
 
   Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
      Me.Opacity -= 0.01
      If Me.Opacity = 0 Then
         Close()
      End If
   End Sub

i hope i don't provide the wrong code.

Hi,

Just to make you spoilt for choice:

In the module

VB Code:

Dim frm2 As New Form2
Dim frm1 As New Form1
 
Public Sub Main()
  frm2.ShowDialog
  frm1.ShowDialog
End Sub

You can use this format to open as many forms one at a time as you wish, but normally you will want a master form to remain open.
