Topic: Needs Help With IF Statement

Subject: Needs Help With IF Statement

I have an IF Statement that I need help with.

Here's the code:

<% If IDValue <> 1 and 14 and 15 and 16 then

%>There are no articles

<%else %>

<%=Content %>

<% end if %>

I would like for the web page to display "There are no articles" if the IDValue is not equal to 1, 14, 15, and 16. I know that my If Statement is not right. How do I work around the bolded code to make it work correctly? <% If IDValue <> 1 then %><%else %><%=Content %><% end if %><%else %><%=Content %><% end if %>

<% If IDValue <> 1 and 14 and 15 and 16 then %> should be:

<% If IDValue <> 1 OR IDValue <> 14 OR IDValue <> 15 OR IDValue <> 16 then %>

If IDValue <> 1 and IDValue <> 14 and IDValue <> 15 and IDValue <> 16 then

Another way is

Select Case IDValue
    Case 1 or 14 or 15 or 16
        ~do something~
     Case Else
        ~do something else
End Select

It's better not to use the ASP blocks in that way (reference to original code)

that wont work. because if its 14 it is allowd from teh first check as its different to 1.

the way to do it is put it in brackets
<% If (IDValue <> 1 OR IDValue <> 14 OR IDValue <> 15 OR IDValue <> 16) then %>

Dpyers is correct above - use AND. Do not use OR. Since the "<>" is evaluated first, if the value is 15, then "IDValue <> 1" will evaluate to true, and the entire expression will be true because of the OR operators.

You could alternatively use:

If IDValue = 1 OR IDValue = 14 OR IDValue = 15 OR IDValue => 16 then

to only display if it is true, which is a much better way to do things. Positive logic is generally better than negative logic.

Also, SELECT CASE is an easier way to do it, and a bit more maintainable if you want to change things later.

Something a little OT.

zaboss's code doesnt show up in IE6, but dj air's quote of it does.

Both the code and the quote show up fine in FF.

Well this has nothing to do with ASP, but with HTML arround it. ASP does not interfere with browsers, as the code is executed before the html is sent to browsers. So, there is something in your HTML code that upset IE, although usualy hapends the opposites (code displaz OK in IE, but not in FF).

Nothing to do with asp at all, just noting that this code displays the table, but not the code text within it in IE6

<table width="100%" border="0" cellpadding="2" cellspacing="0" bgcolor="#FFFFFF">
      <tr>
       <td class="text" style="font-family: "Courier New", Courier, mono;"><pre width=100>
<% If IDValue <> 1 OR IDValue <> 14 OR IDValue <> 15 OR IDValue <> 16 then %>
</pre></td>
      </tr>
     </table>

As another interesting aside, when I go to edit the post in IE, the rte shows blank lines between the code tags - took out all the data between the code - /code tags but left the linefeeds. When I preview the edited post, the code appears as blanks.
