display an alert only once

[AAaron123]

In Page_Load I have the following wanting the popup to appear the first time
(only) that the page is displayed. I get it each time. Can this be fixed?

thanks
Static beenHere As Boolean = False

If Not beenHere Then

beenHere = True

Dim csname1 As String = "PopupScrip t"

Dim cstype As Type = Me.GetType()

Dim csm As ClientScriptMan ager = Page.ClientScri pt

If (Not csm.IsStartupSc riptRegistered( cstype, csname1)) Then

Dim cstext1 As New StringBuilder()

cstext1.Append( "alert('Thi s is ")

cstext1.Append( "some text.');")

csm.RegisterSta rtupScript(csty pe, csname1, cstext1.ToStrin g, True)

End If

End If

Re: display an alert only once

Tried it but it doesn't work.
I'd guess because if I move to another page and return, or if I refresh, it
is not a PostBack.

I think I heed a variable that has a lifetime that lasts until the user
leaves the site.

Thanks for trying to help.

I think I heed a variable that has a lifetime that lasts until the user
leaves the site.

Then use Session...

Session["blnFirstTi me"] = true;

if ((bool)Session["blnFirstTi me"] == true)
{
// run once
Session["blnFirstTi me"] = false;
}

Re: display an alert only once

That did not fix it and I think it should have so I'm now wondering if I'm
missing something else. Like once it's registered it persisted for the
session.

Maybe I need to unregester it the second time or if there is no unregister
maybe I need to register a dummy?

Any ideas?

Thanks

I included the code below

Session("blnFir stTime") = True

If CBool(Session(" blnFirstTime")) Then

Session("blnFir stTime") = False

Dim csname1 As String = "PopupScrip t"

Dim cstype As Type = Me.GetType()

Dim csm As ClientScriptMan ager = Page.ClientScri pt

If (Not csm.IsStartupSc riptRegistered( cstype, csname1)) Then

csm.RegisterSta rtupScript(csty pe, csname1, cstext1.ToStrin g, True)

In Page_Load I have the following
Session("blnFir stTime") = True

There's your problem - you're resetting the Session variable to True every
time the page loads.

This needs to be done in Session_Start.

Re: display an alert only once

I wonder what static/shared does in Asp.Net.
Something different then in windows?

The same as in Windows, but here the (single) webapplication is shared
between all users!
So if you want to keep 1 value for the entire site - fine.
If you want to keep 1 value per user - use Session.

Re: display an alert only once

What about if I want to maintain a counter of how many tine I was vested.
Would you do that with a file?

Thanks for the info below

AAaron123 explained :

I would keep counters in a database. Usually a site runs as a user that
can't write files, unless you specifically enable it.
For a file you would have to read it, decode the counter value,
increase it and write it back. And you would have to do this within a
"lock" so that some other request wouldn't interfere.
For a database you would just issue a command "update counters set
mycounter = mycounter+1" and the database should do all the locking
needed.
