If statement problem

chris1012 · September 8th, 2008, 04:28 PM

ok am a complete noob when it comes to programming but i enjoy learning about recently i picked up one of the wrox books and i was wondering if one of you guys could help me out with a basic if statement problem

heres what i've got so far
<%
Dim strgay
strgay = request.Form("alias")
Response.Write strgay
%>

what am trying to do here is basically return a value from a webpage that has input field within a form to this webpage currently coding but i want the string variable entered to be conditional i've try different if statements but nothing i was wondering if someone could give me an example of some code for example if someone entered the name chris it would use the response.write statement and say access denied

i'de appreciate any feedback thanks in advance

in opposite world i love programming

Code:

<%
Dim strgay
strgay = Trim( "" & request.Form("alias") )
If strgay = "" Then
    Response.Write( "No alias given...so just go away" )
Elseif LCase(strgay) = "chris" Then
    Response.Write( "We hate you, Chris.  Go slip on a banana." )
Else
    Response.Write( "We love you, " & strgay & ".  Welcome!" )
End If
%>

Now... This really looks suspiciously like you are coding ASP and NOT ASP.NET! Because you do
     Dim strgay
and
     Response.Write strgay
and with ASP.NET, using VB.NET, you would normally do
     Dim strgay AS String
and
     Response.Write( strgay ) ' the parens are *necessary*

So if you aren't REALLY coding ASP.NET, you are posting in the wrong forum. And if you ARE coding ASP.NET/VB.NET, then you should be sure to ALWAYS compile all your code with
     Option Strict On

right ok yeah i am working with asp my bad but still the forum said asp.net and asp but any whos not to worry al sort this out one last question though before hand i've got all my if statements working like a charm but i now want to embed an image into an ifstatement and write a statement out aswell for example heres what i've got so far

ElseIf LCase(strgay) = "nick brown" Then
Response.Write ("YOUR NO PETER LEAVY: " & strgay & "<IMG SRC="nick.jpg">")

i can't see whats wrong tbh but am guessing its to do with the object type i've used in asp any feedback would be much appreicated thanks

No, this forum specifically says it is "ASP Net 3.5 Beginner".

It is the GROUP of forums labelled "ASP.NET and ASP", but there are two separate forums for old-style ASP.

Anyway...

Response.Write "YOU'RE NO PETER LEAVY: " & strgay & "<IMG SRC=""nick.jpg"">"

To put a " mark inside a quoted string in VBScript (or in VB.NET, though you don't care about that), you use a pair of quote marks, as shown there. (This is, not so incidentally, the same scheme for using apostrophes in SQL queries.)

Notice that with VBScript you should NOT use parentheses with Response.Write. They don't really hurt, except that they cause a minor performance hit (microsecond or two), with Response.Write, but there are other circumstances where they can have strange side effects. I wrote a loooonnnnggg article on this back in 2001, if you care. But you probably don't.
