handling special characters in asp 2

[sweetleaf]

hi,

Does anyone have any idea as to what might be causing the following:

I have a hyperlink which reoloads an asp with querystrings
x,y,z.

x,y and z load values like C1,VR,7T into correlating text boxes.

Everything works fine except when x,y or z contains values with special characters like C#,B+ or #I..

Does anyone know what I can do to alleviate this?

Any help sure would be appreciated a lot!

The reason that you are having a problem is because url's cannot contain those characters. You may notice when you have a space in a url it changes it to %20. There is a function ASP to convert a string to a valid url, Server.URLEncode(str) will encode the special characters in str to be ok.

yea what tawrn said.

Try
Response.Write Server.HTMLEncode(strToSend)
for data that might contain Special characters.

Hi guys,

thanks for all your input - but I've tried (sorry forgot to mention) server.urlencode and server.htmlencode already and still i'm having this problem - don't know why..

can you show us the code used to get the querystring data and then redirect

 

[sweetleaf]

heres the link on my page which reloads the page with querystring values:

<a href=&quot;service.asp?z=<% server.urlencode(Response.write(rst(&quot;SERVICE_CD&quot))%> &x=<% Response.write(rst(&quot;DESC1&quot)%> &y=<% Response.write(rst(&quot;DESC2&quot)%> &aa=<% Response.write(rst(&quot;DESC3&quot)%>&quot;>Edit</a>

.. the querystring &quot;z&quot; uses urlencode (i've also tried htmlencode).

thanks guys and gals

<a href=&quot;service.asp?z=<% server.urlencode(rst(&quot;SERVICE_CD&quot)%> &x=<% Response.write(rst(&quot;DESC1&quot)%> &y=<% Response.write(rst(&quot;DESC2&quot)%> &aa=<% Response.write(rst(&quot;DESC3&quot)%>&quot;>Edit</a>

Ah, forget what i said above, try this:

<%

Dim Service_cd, desc1, desc2, desc3


'#put all data in a string...

Service_cd = Server.URLencode(rst(&quot;Service_CD&quot)
desc1 = Server.URLencode(rst(&quot;DESC1&quot)
desc2 = Server.URLencode(rst(&quot;DESC2&quot)
desc3 = Server.URLencode(rst(&quot;DESC3&quot)

'# NOTE: <%=&quot;An &quot;=&quot; sign is the same as using response.write&quot;%>

<a href=&quot;service.asp?z=<%=Service_cd%>&x=<%=desc1%>&y=<%=desc2%>&aa=<%=desc4%>&quot;>Edit</a>




%>

Snowboardr,

I want to try your code fix but don't quite understand what you're doing. Can you break it down for me... I'm a beginner. Thanks.

Your code read:
<%

Dim Service_cd, desc1, desc2, desc3


'#put all data in a string...

Service_cd = Server.URLencode(rst("Service_CD"))
desc1 = Server.URLencode(rst("DESC1"))
desc2 = Server.URLencode(rst("DESC2"))
desc3 = Server.URLencode(rst("DESC3"))

'# NOTE: <%="An "=" sign is the same as using response.write"%>

<a href="service.asp?z=<%=Service_cd%>&x=<%=desc1%>&y=<%=desc2%>&aa=<%=desc4%>">Edit</a>




%>

this might be of assistance as well in your issue :
it's just the reverse of a URLEncode, i still have yet to write a HTMLDeCode

function URLDecode(str)
	dim re
	set re = new RegExp
	str = Replace(str, "+", " ")
	re.Pattern = "%([0-9a-fA-F]{2})"
	re.Global = True
	URLDecode = re.Replace(str, GetRef("URLDecodeHex"))
end function

' Replacement function for the above
function URLDecodeHex(match, hex_digits, pos, source)
	URLDecodeHex = chr("&H" & hex_digits)
end function
