just closing the main form

[yaniv]

Well, i think that i understood that i have to create a new object to open form and then i use the object to close the form, but can i close the main form (the start page)?

 

[wyrd]

C# - this.Close();
VB - Me.Close()

 

[yaniv]

it's doesn't work.

this is my code:
(i want the button to open the new form and to close the menu)

private sub button1_click
dim frm as new form1()
frm.show()
me.close
end sub

and it does't work, the me.close is closing (as i see it) the new form.

well, i discovered that when i use the me.close and close the main form i just closing the all program.

what i"m looking for now is a way to close the main form while the second one is open and to reopen it when i close the second.

what i did is to use sub main to create te main form, and i can now hide it, but when i"m in the second form, i can't find the way to recognize the main form.

i just can't give him a name that the second form recognize.

do you idea?

Did you dim the form as Public in your sub main?

What about Application.Exit() ?

 

[yaniv]

You can't public a form in a shared sub (which is the 'main' sub).

application.exit is closing the entire program.

You need to modify your sub main (or create one if you don't already have one) and use Application.Run() (note no parameters) to start an application-wide message loop that isn't dependant on any one form. The default behaviour is to have your message loop based on a main form, and therefore it shuts down when that form does.

This will solve your problem, but introduce a new one - when you have a message loop that doesn't depend on one form, you must then manually call Application.Exit() when you really do want your application to close.

Oh.. sounded like you were trying to close the entire program. Sorry.

well i changed the sub main, but i do have to start with some form, no?

so i used this code:

    Public Shared Sub main()
        Application.Run()

        Dim frm As New Form1()
        frm.show()


    End Sub

but nothing happen!!

i do think i miss something, it supposed to be simple, no?

Show the form before the Application.Run() call, that ought to do it.
