Returning Values - Which Is Faster? ByRef Sub Or Value-returning Function
What is a faster/better coding practice?
Method 1:
Code:
Sub myFunction(byRef x)
x = x + 1 ' do something with x
End Sub
x = 7
myFunction(x)
response.write x ' shows 8
Method 2:
Code:
Function myFunction(x)
myFunction = x + 1 ' do something with x
End Function
x = 7
response.write myFunction(x) ' shows 8
Also discuss considerations when there are more than one variables that need to be changed.
Sub Returning Values
I was under the impression (according to all the tutorials) that a Sub differs from a Function in that it doesn't return a value. Therefore I interpret this as meaning if a function is initialised at the top of a page and called at the bottom the result won't be returned to the place it was called i.e. the bottom of the page.
This clearly isn't right though as both Functions and Subs return a value to where they are call from.I want to display the results of a task in a position on the page that is before the task has been carried out.
Therefore if I create a Sub where I want the result to be displayed I assumed that when I call the Sub it would display the results where I wanted i.e. above the task. This isn't happening?
Returning Multiple Values From A Function
I've looked around the net and searched this message board and haven't been able to find a solution to this problem. An application that I am currently making pushes and pulls data from SQL. One stored procedure is very important and returns many values.
I call this sp many times in my script and wanted to put it in easy to manage function, sub, or whatever works. The problem is that it returns about 10 values that I would need to return from the function back to the standard asp. Code:
Returning Multiple Values From VBScript Function
I am using both VBScript and JavaScript functions in the same ASP file. All I need to do is to retrieve some values which are calculated in the VBScript function, to JavaScript. The call to the VBScript function is made through a JavaScript function. Code:

Using Functions
I have a file i created
it contains several functions, and some other code to build a string based on diffrent vars.If i run this file standalone, it works absolutly fine. However the problem comes when i include it half way in another script.
I get the following..

This is line 2

Functions
I am searching for a function that can separate a string var to some string vars and devide the string by "," marks, os this possible?
example:
str1 = "2,34,1,54"
and I want "2","34","1" and "54" be devided and inserted into new vars, or an array var, is their a VBscript function for this?
I have made a function myself that does this using ths Instr and the Mid functions, but its quit messy and I don't wan't to have to insert it in every page I make, Any Ideas?

Functions In Asp
I've written the following function but somehow the output is not what I want it to be. Can someone explain to me what i'm doing wrong?
function fn_piping(inputWaarde)
outputwaarde = inputwaarde
Response.Write outputwaarde & "<BR>"
if i = 1 then
i = 2
call fn_piping("thisshouldbethefinaloutput")
else
fn_piping = outputwaarde
end if
end function
i = 1
figure = fn_piping("bla")
Response.Write "<BR>" & figure
So 'thisshouldbethefinaloutput' should be the final output, but it doesn't output anything?!
Sub/Functions With FOR
I need a current record in the database for it to work but I have another page that uses this same code and it works fine on that and the only thing different in the coding is where the information is being pulled from in the database and when i first copied & edited the page it worked fine but now it doesn't and i've worked on it .....

How To Convert Escape Values In To Actual Values
i need to convert the escape values which are by mistake updated in DB.
example:
this is a sample text string
is updated in DB as

here %20 is the space.
like wise there are many entries for :,'
is there way that i can update all this in a update statement?
or use asp to to update the records?
Calling Functions...
Where's the best place for me to include all my functions that I want to call throughout different pages? Should I just put them all in one ASP file and include that page on every page? Or use global.asa somehow (how??)?
Anyways, I was just wondering because I didn't want to slow things down if I could help it (I didn't know if having another big file attached to every page when I'm just using a small portion of it was very effective or not)
Date Functions

ASP Apps And Functions
Over my years developing ASP applications and writing asp code in general I have created a library of nice little apps and functions that I use over and over again.
I was "thinking" about maybey setting up a site with all my useful functions, subroutines, and possibly applications for people to download and hopefully donate some money if they use them. Perhaps even have some apps for sale only.
The apps will mainly be my useful plugin developments such as guestbook, gallery, login system etc. My question however is do you think it would be worth the time and effort? Do you find yourself using plugins a lot?
I defo think the functions could be handy but again how many of you search for functions to help you out or indeed how many of you currently use functions you have gotten from other people? Would you donate something if you used them?
Mayby some of you have already done something like this and can let me know how you got on?
Math Functions...
Didn't remember if anybody had started started like this, but I decided it would be cool to start it again. If you have a math function request ask it below, or if you have made one then add it:

Multiple Functions
I have some code I am working on. One function reads a file using fso, then

function splits the lines up and will return one value.
Is there a better way? Is handling this many array which are basically the
same going to cause some server distress
Lack Of Functions

Reusing Functions
I have been developping a webpage in ASP for about 4 weeks now and I have noticed that I am rewriting similar functions in pretty much every page i make. So I was wondering if there is a way to make some particular functions global so that you can use them in any page. The functions will depend on the session id, but I don't know if i can declare session functions or not.

In this function i pass variables to it to find out if a record exists, what i want to do next is call this function and if a record does not exist pass a variable out like Statement = False and then pick up that value on the page that i call the function.
Can this be done? I was thinking perhaps using a Session? Code:
NOW() And DATE() Functions

VBScript Functions
I'm a PHP programmer. That said, I recently began a job where a good third to half of the applications are written in ASP.NET. VBScript, to be precise. As I've done programming for years (C/C++, PHP, JavaScript, BASIC... the list goes on and on), picking this up hasn't been too difficult, but I now find myself facing a question that I simply cannot find an answer to anywhere:
Can one define a function that has optional parameters in VBScipt?
If not, can it be done in C#, and can C# code be easily integrated into pages written in VBScript?
