server-side validation
I posted this yesterday afternoon, but for some reason, I don't see it in my
newsreader, on either of my 2 computers. So I am re-posting. I'd like to see if there is any guidance in the form of sample code or a tutorial for server-side validation. Specifically for the thing I am trying to do, if a user types too many letters into Textarea, then they see an error on the screen. I was able to catch most occurrences of this error with client-side javascript. However, I'd like to handle it server-side in order to catch those cases that get by the javascript for whatever reason. If I could just catch the error before it gets displayed, then display a warning in red letters in a pretty format, then that's all I'm hoping to do. I went to ASPFAQ.com, didn't find anything there. I also did a search of this forum and didn't see anything. I know conceptually what I want to do, but I am not sure how to go about it. sTemp = Request.Form("txtaSomeTextArea")
If Len(sTemp) > 1000 Then Response.Redirect "/?err=1&tmp=" & sTemp End If '// Example form <% If Request.Querystring("err") <> "" Then Response.Write "Error: Too many characters<br><br>" %> <form action="thispage.asp" name="frmTemp"> <textarea name="txtaSomeTextArea"><%if len(request.querystring("tmp") > 0 Then%><%=request.querystring("tmp")%><%end if%></textarea> <input type="submit" name="btnSubmit"> </form> Show quote "middletree" <middlet***@htomail.com> wrote in message news:e7bqwVOGFHA.2296@TK2MSFTNGP15.phx.gbl... > I posted this yesterday afternoon, but for some reason, I don't see it in my > newsreader, on either of my 2 computers.

It comes from a completely different direction
from what I was thinking. I was thinking I'd have to come up with code which read the SQL Server error after it had been generated and displayed my customer message instead of the SQL/ASP error. Your solution captures the problem before it gets that far. I like this. I see where it will take some work to capture all the other parts of the form and put them back into place, but it will be worth doing. thanks very much!
