How do you display a msgBox in a web application?

[Guest]

I've tried the good old fashioned msgBox but I get:

It is invalid to show a modal dialog or form when the application is not
running in UserInteractive mode. Specify the ServiceNotification or
DefaultDesktopOnly style to display a notification from a service
application.

In server-side code, you can't.

On the client,

<script language="JavaScript">
<!--
alert("Your message here");
-->
</script>

or

<script language="VBScript">
MsgBox "Your Message Here"
</script>

But note that some browsers don't like VB Script.

Hi,

you have to use JavaScript or VBScript to show a MessageBox in Web apps.

However and If you undertand Spanish, there is a very good article in MSDN
Spanish, wrote by another MVP, that teach as put and use MessageBox in Web
apps.

The URL of this article is:
http://www.microsoft.com/spanish/msdn/comunidad/mtj.net/voices/art120.asp

I hope that helps.

Kind Regards,

Roman,

Maybe this can help you as well?

Private Sub Page_Load(ByVal sender As _
System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not IsPostBack Then
Dim str As String = "<script language " & _
"=javascript>alert('Click on the button?');</script>"
Page.RegisterStartupScript("Startup", str)
End If
Me.Button1.Attributes("onClick") = _
"alert('I hope this helps a little bit?')"
End Sub
