Starting a .Net app.

[papa_k]

Hi.

 

I have come across some problems with .Net which im sure are simple to fix if you have even just an ounce more knowledge than me...

 

(the .net book i have is crap and doesn't help with these simple problems)

 

Firstly i wish to start the application with a splash screen followed by a login screen. once login has been authenticated, the app will go into a main menu screen.

 

what is the best way to do this?

 

when i first attempted it i opened up the splash screen, then the login screen, but closed the splash screen (no longer needed) which then inturn closed the login screen and the app. Probably (if not def.) because i called the login screen within the splash screen. as soon as the splash screen was closed variables (class forms) within the splash screen then close, and the app then shuts off.

 

so i read that i could create a sub main which would all the splash screen, then the login screen and so on.

 

I did this and it worked. I'd set the project start up to be the sub main. but since i did that i thought that the module would have to be called somethin else, liks startup. as its only run once with the aim to load the splash screen and login form.

 

everything else can be run using the class methods and opening forms from within forms (from main screen onwards).

 

i renamed the sub (to sratup) but couldnt find it in the options to use it as a start up object.

 

i then deleted the renamed item and created a new one again with the needed information to open the splash screen and login screen.

 

i cant find the new sub in the object start up menu, sub startup, but the flaming sub main is stil there (which i have infact deleted and is to all intense and purpose not part of the project anymore).

 

what have or am i doing wrong.

 

if you have questions, or cant understand what i am getting at please reply and say what is up.

 

VB6 i know, .net i am very new with and im strugerling because it seems to wanna be helpful but it just seems to over complicate things (especially when you change your mind).

 

i am a patient person - this is the second attempt at using .net - i know its probably the way forwards but i still need to be convinced.

 

Please help.

 

Cheers,

 

Papa.

Create yourself a Sub Main, and run two separate message loops, one for the lifetime of your splash form (which should have a timer on to Close itself) and then one for your main application.

 

Dim splash As New frmSplash()
Application.Run(splash)
Dim mainForm As New frmMain()
Application.Run(mainForm)

Dim splash As New frmSplash()
Application.Run(splash)

thanks for this.

 

i have done what you said.

 

i have created a module and called it Sub Main.

 

This is set as the start up object for the project...

 

BUT...

 

I get two errors...

 

'Sub Main' was not found in testProj'

 

...and for this code...

 

Module Sub_Main
   Dim test As New frmMain()

   Application.run(test)
End Module

 

i get this error...

 

Declaration Expected

 

What am i doing wrong?

That isn't a Sub Main, that's a module called Sub_Main. Set your startup object to Sub Main, and then create yourself a new class that looks something like this:

 

Friend Class MainClass
   Public Shared Sub Main()
       'Insert the code I gave you earlier
   End Sub
End Class

thanks divil.

 

sorry for being a fool - as i said new to, 'bit of a school boy error' though...

 

d'oh.

 

thanks again.

sorry about this - i get the same problem as before. i have tried to sort this out on my own, but i cant

 

the splash screen appears - i close it (or the timer shuts it)

 

and then the main form appears and then disappears.

 

heres the code from main. what the hell am i missing. i have a msgbox that pops up in the main form load statement (yes, it does appear)

 

Friend Class MainClass
   Public Shared Sub Main()
       Dim formSplash As New frmSplash()
       Application.Run(formSplash)
       Dim formMain As New frmMain()
       Application.Run(formMain)
   End Sub
End Class

It shouldnt disappear, do you have any code in Load event that could cause it to close?

[papa_k]

Public Class frmMain
   Inherits System.Windows.Forms.Form

- Windows Form Designer Code

   Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
       MsgBox("this")
       Me.Show()
   End Sub
End Class

 

is what is in the form.

Are you disposing of the splash form property? In the timer event, it might be worth disabling the timer before calling Me.Close() and me.Dispose()

a review of the problem

 

this is the code:

 

       Dim formSplash As New frmSplash()
       Application.Run(formSplash)

       Dim formLogin As New frmLogin()
       formLogin.Show()

 

this is what happends:

 

-----------------------------------

 

sub main starts

 

the form splash is intialised

 

the form splash is shown

 

the form splash closes

 

the form main is intialised

 

the form main is shown

 

the sub main reaches end sub

 

the application ends.

 

-----------------------------------

 

 

people must have carried out a similar way of starting an application, and yet i have not had any real solutions to the problem.

 

it appears that the app. is reaching the end sub and exiting, but it doesnt do this if i only have:

 

       Dim formMain As New frmMain()
       Application.Run(formMain)

how do i do this? disable the timer...

 

i have a me.close() in the timer event

 

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
       Me.Close()
   End Sub

[divil]

myTimer.Enabled = False

[papa_k]

example?

 

please could someone post a example vb.net app zip file with a simple application that

 

shows a splash screen frmSplash

 

loads a login screen frmLogin

 

if you enter 'testdrive' as a user name

 

and 'keys' as the password

 

it then opens a main frmMain

 

else does nothing.

 

i cant get my app to work and i am very very frustrated!!!

 

i know i should be able to get this to work, but i just cant!
