I want to use javascript to do the equivalent to this Windows Form
code on an asp.net webpage using VB:

if x = 2 and y = 3 then
messagebox.show("This is a message")
end if

Many of the code I've found appears to be obsolete or includes lots of
other bells and whistles (adding an alert to a datagrid or a control
attribute), which I do not need and only find confusing. I'm using
Web Developer Express 2008.

Help would be appreciated! Thanks!

if (x==2 && y==3)
alert("message");

How do you do that from the vb codebehind?

Probably something like:

If x = 2 And y = 3 Then
ClientScriptManager.RegisterStartupScript(Me.GetType, "message",
"alert('This is a message');", True)
End If

Sure, it's inline javascript. I think, he didn't mention that it must
be from the codebehind.

In addition to example by Mark, this can be done using public
variables as

vb.net
-----------------
Protected Dim x As Integer = 2
Protected Dim y As Integer = 3
-----------------

aspx
-----------------
if (<%=x%>==2 && <%=y%>==3)
alert("message");
-----------------

I think it should work as expected.
