OK, I'm trying to make an ASP page that I can link to and use as a image display. Basically, trying to make it so that I can do "http://xyz.com/picture.asp?pic=pic1.jpg" and "picture.asp?pic=pic2.jpg" and so on. Right now, I just have an ASP file that looks like this:
<%
if Request.Querystring("pic") = "pic1.jpg" then %>
<img src="pic1.jpg" border="1">
<% end if
%>
<%
if Request.Querystring("pic") = "pic2.jpg" then %>
<img src="pic2.jpg" border="1">
<% end if
%>
I realize this probably isn't the most efficeint way of doing this (especially if I were to have a couple hundred entries,) but my ASP knowledge is very limited at this point.
ANYWAYS...
My question...
I need to make a default image so that if none of the other Request.Querystring's match, that image is displayed. I'm not sure how or where I would put the else(?) statement so that's why I'm asking. I tried just doing a:
if Request.Querystring("") = "" then %>
statement but then that particular pic always is displayed.
Thanks to whomever can figure this out.
Scott

You can use a Select Case statement:Select Case Request.QueryString("pic")
Case "pic1.jpg"
Response.Write "<img src=""pic1.jpg"" border=""1"">"
Case "pic2.jpg"
Response.Write "<img src=""pic1.jpg"" border=""1"">"
...
...
Case else
Response.Write "<img src=""defaultpic.jpg"" border=""1"">"
End SelectIf your images are named pic1, pic2, etc., you could change your url to something like: http://xyz.com/picture.asp?pic=1 and put the url like this:x = Request.QueryString("pic")
<img src="pic<%=x%>.jpg" border="1">But that will only work if your pics files are numbered. And your default picture would be called pic.jpg.
Of course I was beaten to it.

OK, now Davio...
you said that I could also do a
quote:
x = Request.QueryString("pic")
<img src="pic<%=x%>.jpg" border="1">
but I've ran into another problem...
If someone puts text in as the QueryString then we get an error.
Right now I have :
strWhatPic = Request.QueryString("pic")
if strWhatPic = "" then
strWhatPic = 0
end if
(green part put in so if left blank it's replaced with 0 )
My question is how can I make it so that if anything besides a number is put in as the QueryString, it can set the strWhatPic to 0?
Thanks again.

strWhatPic = Request.QueryString("pic")
if strWhatPic = "" or IsNumeric(strWhatPic) = False then
strWhatPic = 0
end ifYou can try that.
