forms in vb.net

[amtrac24]

hi guys,

I am trying to load another form from the orignal form. For example

lets call them
form 1
form 2

form 1 is a logon page
form 2 is the main menu page

Private Sub cmdLog_In_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLog_In.Click

Dim Main_test As New Main()

If txtVisUsers.Text = txtUser.Text And txtVisPW.Text = txtPassword.Text Then
Main.Show()
Me.Close()

Else
system_commands.Invalid_PW()
reset_form()

End If
End Sub



When i run this is closes the whole appliation. I searched the web and a book i have and it should work.

PS. I do not wont to leave form 1 in memory so don't suggest doing a form1.hide()

Can someone let me know if they have succesfully done what i am trying to do.Thank you for your help guys.

Of course the app ends, when you have Form1 as startup and then close it. I would do this the other way around:

1. Set Form2 as startup.
2. Hide it intially.
3. .ShowDialog() on Form1, your logon form.
4. If a successful logon, make Form2 visible.

ok yeah thats a work around. Lets say though if I want to go to form 3 from form 2.
I would say

dim form3 as bla bla

form3.show()
me.close

I guess my real question is how do i load a form from a command button and then close the form which had the command button and take it out of memory.

I would say that typically does not happen. An application normally has a start point -- a start point that a user may get back to, so they may "start over." If you wish to get rid of your inital form, then the only way to "get back" is to create a new copy. This means that the user loses all settings that may have existed in the original copy.

If you really must do this, then you can always use Sub Main() as your start point for your application.

dim form2a as new form2

from2.show
unload me

Unfortunately, Unload Me has no relevance to VB.Net. VB.Net is much different from VB 6 in that it is completely Object Oriented.

yeah i was just playing around with it. I realized that what ever the starting form is you cant do a .close(). So basically If i have 3 forms (form 1,2,3) and my starting form is form1. No matter what I can not use a form1.close() otherwise it will close my application. On my form 2 page if i do a

dim form3 as new form3
form3.show()
me.close

It will take form2 out of memory and show form 3. Creo I want to thank you for your help. Alll the books that i looked at really didnt explain it. i really appreciate it.
