Revisiting ASP 2

[crackon]

I'm revisiting some ole ASP code and wondered what actual this does?

Set params = Request.QueryString

Hi,
If the page with this code were called by a URL like this:

http://myserver/myapp/handleparams.asp?Test='123'

Then that code would set the variable params to the passed string : Test='123'
- probably to use later in the page in a query to a database.

so if it was test=123&great=yes would that be params(1) = test=123 and params(2) = great=yes

?

Hi,
Great site for returnees ( or beginners) in asp to know about - star to guitarzan- I should have mentioned it myself ( and been more clear on my answer) :

In your original post the a URL like

http://myserver/myapp/handleparams.asp?Test='123'

woul dbe handled in your page with a revised form of what you had:
Dim params
params = Request.QueryString("Test")..
Then the param variable would then be set to '123'

For your second example :

http://myserver/myapp/handleparams.asp?test=123&great=yes

You would have 2 variables in the handleparams.asp page:

Dim param1,param2
param1 = Request.QueryString("Test")
param2 = Request.QueryString("great')

then
param1 = '123' and
param2 = 'yes'

Hi,
Just a note about your example:
No semicolon between variables in the QueryString, so it should have been:

http://myserver/myapp/handleparams.asp?test="123"&great=yes

It somehow showed up when I copied yours...

So its the result on each parameter not all of it?

Hi,
Yes - the QueryString is a method of passing named values to some other page for action...The page code then checks the name to get the value...
Here is an example that I have used to get information for a Crystal Reports application:

I pass a URL like this:

http://myserver/crapps/reportviewer...mes=officeID,role&Pvals=2,3,4;Mgr,Exec,Intern

On the reportviewer page I have( in part):

'Get the values
Rid = Request.QueryString("ReportID")
NbrParams = Request.QueryString("NumParams")
If NbrParams > 0 then
ValStr   = Request.QueryString ("Pvals")
NameStr = Request.QueryString ("Pnames")
arrVals = Split(ValStr,";")
arrNames = Split(NameStr,",")
End If

This reads the QueryString and gets values for
How many parameters are in the string and
The values for the each one of those

I then create 2 arrays with the name and value lists to create what I need later to pass to the Crystal Report viewer object ( no need to detail that, this is just to show how a QueryString can be used).
