removing empty elements

Hi Guys,
I have this form that collects text values and I use VBCrLf as delimiters to tell one element from another. Sometimes, I get several empty elements. Is there a way to remove those elements?

Thanks in advance

I don't get it

You have a <form>...</form> with <textboxes> right?

Then what?

The user submit's your <form>...</form> and you try to retrieve the values from your <form>...</form> ?

Is that it?

I have an ASP processing file that takes the values in the textfield and make it into an array, based on VbCrLf(carriage return) as delimiters. I am wondering if someone enter an empty line, how do you remove it?? (I inserted some extra lines (empty), how do you remove it??)





I know for perl, you just Chomp the array, but what about for vbscript??

While you're taking/retrieving the data from your <textfield> make/use the Trim() function so:

<%
Dim strTextBox1
Dim strTextBox2

strTextBox1 = Trim(Request.Form("txt1"))
strTextBox2 = Trim(Request.Form("txt2"))
%>

Hope this makes sense!

hi Vince, thanks so much for your help.

But that's not the problem I have.

my input is not a textbox, but a textfield consisting of many newlines.

so the variable will look like

txt1 VBCrLf txt2 VbCrLf txt3 VbcrLf.....etc

and I do use Trim to remove spaces.

and here are the problems
someone may put in things as such below:

VbCrLf VbcrLf Vbcrlf txt1 VbcrLF txt2 VbCrLf VbCrLf VbCrLf

so when I split on VbCrLf... I get array size of 7 when I should've just gotten an array size of 2...
Hope that explains my situation.

Ok so try replacing the VbCrLf with a space -->" "<--

then use the Replace() function and the Trim() once again

you say you have this:
VbCrLf VbcrLf Vbcrlf txt1 VbcrLF txt2 VbCrLf VbCrLf VbCrLf

Once the replace is done, you'll have this:
" " " " " " txt1 " " txt2 " " " " " "

Well the double quotes won't be there of course, its simply so that we can see that the Replace will replace the VbCrLf with a space --> " " <--

then you Trim() that so you end up having:
txt1 " " txt2

then you Split() on " "

So :

Response.Write Split(..., " ")(0) 'Should give you txt1
and
Response.Write Split(..., " ")(1) 'Should give you txt2

Hope this helps!
Sincerely
