Hello
I have problem with getting value of a form field in a same page. I try to get the value of hidden filed with a CStr(request("a")).but it can't be done.
I did it as below:
1-set the value of hidden field
2-Dim MM_a
MM_a=CStr(request("a"))
if MM_a="1" then
do something
end if
but it cant get the a value that is my hidden field.I tried CSt(request.form("a")) too but it didn't work either.
i would be very happy if some one tell me the solution.
thank you

Is the hidden field named "a" ?

"The one language all programmers understand is profanity."

yes,the hidden field name is "a"

When the page first loads the hidden field wont have a value, at least not that ASP can capture. When you click submit, however, that field should have a value and as long as your form handler is set as the correct page you shouldnt have a problem.

So the pseudo code is something like this:

--Page Load
if hidden field is empty
  do nothing and display page

if hidden field is not empty
  process values and do other things

If the value isnt displaying or such, you have a logic error

I checked my code and i found that it cant set the value of hidden fields to a text box.let me explain you the excat thing that i want:
1-insert 8 hidden fields for 8 textbox
2-when each textbox change
set the hidden.value="1"
3-a=hidden1.value
b=hidden2.value....
h=hidden8.value
4-MM_Changecode=a&b&c&...&h
5-the textbox value is MM_Change
it makes MM_Changecode correctly(i've tested it with msgbox) but it doesn't show it in textbox
would you please help me to fix it
thank you

You have completely lost me as to what you are trying to do...

excuse me, I didn't explain it in a right way.I have 8 texboxes.i want to have a string that shows if a text box has been changed or no.each character of this string belongs to a textbox.if the value is "0" it means it didn't change and if it is "1" it means it changed.then put this string in a textbox to insert to a database.so I insert a hidden field for each textbox that will get the value "1" if text box changed(the default value of each hidden field is "0"). and at the end make the string and put it in text box.it makes the string correctly but it doesn't show it in textbox.do i have wrong logic or the way i write codes is incorrect????thank you for your help

I ask a phew questions to clear up some merckyness. Are you calling a new page or file after getting this data? Now after some one has changed the data in one of the the textboxes where do you go next after the data aquisition?

I hope i can explain what i want to do.This is an update page.and because it is important for me to to know if some fields has been changed or no i used a textbox that gets the value of hidden fields.and from that string i can understand if a field was changed or no.

Ok so:

If a user changes field 1 hidden field 1 changes to some value. So on the backend you would do something like:

Dim valueA
Dim hiddenA

valueA = Request.Forms("fieldA")
hiddenA = Request.Forms("hiddenA")

If hiddenA = "something" then
   Do this
Else
   do this
end if

does this help?
