[2005] Do "x" only at first runtime

[fredde_jason]

Hello,

I'm making a program and I want to x code to be executed only at the first runtime. How could i make this? I have no idea what code it could be, but you could se how I mean with this code:

Private Sub TestIfFirstRun
If App.FirstRun Then         ' App.x is from vb6 but its just an example

         MsgBox("First Run")

Else

         GoTo start

End If

start:

MsgBox("Start")
End Sub

If anybody knows if it's any API or function for this please reply!

Go into your project properties (Project menu, the option at the very bottom), then click the Settings tab.
Here you can create settings for your application. Create a setting of type boolean, set its value to True, and give it a good name...say "FirstExecution".
Here's the code you'll need now:

If My.Settings.FirstExecution Then
            'Do whatever you want.
            My.Settings.FirstExecution = False
        End If

This can be done in many ways, so this is just one of many.

Go into the Settings tab of the MyProject page and add a variable there with a scope of User. Call it "FirstRun" or something and make it a Boolean.

Then in your code:

Private Sub TestIfFirstRun
If My.Settings.FirstRun = False Then

         MsgBox("First Run")
         My.Settings.FirstRun = True
         My.Settings.Save

Else

         GoTo start

End If

start:

MsgBox("Start")
End Sub

Oi! Atheist beat me to posting a solution again.

i don't recall, but if my.settings is saved automagically, then you need to set it to true. of course the boolean could just be dim'ed

Dim OneTime as Boolean = True


If OneTime then
onetime = false
'one time code here
end if

Thank you, it worked!

OT: When I copy VB code from the VB code box you put, I get all the numbers of the lines like

1.
2.
3.
4.
5.


Can i do anything about this, because if I copy like 70 lines it's very annoying!

[Tom Sawyer]

You could use our code as a suggestion of what to do and then write it yourself. That would solve the problem.

i totally misunderstood. i thought it was code to run once each time the app was run, not just run one time.

i gotta ask, what are you trying to do just once? i ask because maybe my.settings isn't right, but without knowing the WHAT it is hard to know.
