Using ASP/VBScript, Is it possible to populate an array with variables in such a way that later changing the value of the variable will change the value stored in the array?
For instance:
dim var1, containerarray
var1 = "Initial Value"
containerarray = array(var1)
var1 = "New Value"
for each x in containerarray
response.write("The value is: "& x)
Next
Would ouput "The value is New Value"
In working with arrays, I have found that I am unable to dimension and array
with a variable that has an integer value but I can redimension one this
way. I haven't see any information that tells me if this is a requirement,
although it appears to be because I get an error if I try it.
Ex.
Dim b
b = 10
Dim a(b) ' this errors out but
Dim a() ' this
Redim a(b) ' works
Code:
what is the default behavior of asp for passing values to a function, byRef or byVal? i was under the assumption that if you do not specify, then it defaults to passing the parameter byRef. so for example, the following function is accepting param1 and param2 as
"byRef" parameters:
function myFunction(param1,param2)
'do something
end function
am i correct?
Is it possible to create an array with variables inside it, like the following example
Example:
var1 = "1"
var2 = "2"
var3 = "3"
my_array=Array(var1,var2,var3)
For i=0 To 3
if(my_array(i) = "1") Then
Response.write("blahblah")
.

Passing Dictionary object byref
Ive created an ASP class that uses a dictionary object which is filled
from a recordset. It passes the object to the propterty of another ASP
class byref:
Public Property Let dicReplaceVars(byref vdicReplaceVars)
set p_ReplaceVars = vdicReplaceVars
End Property
Private p_ReplaceVars
where it is used in this other class a few times to replace values in
an array: Code:
I have an array varibles in ASP script and i want to use these
varibles again in client Script (in VBScript) .
I know that cookies can store an array of values, which can be accessed like this:
tempid = Request("cookiename")(i)
Is it possible to use session variables in the same way? Store a array of values in the same session variable and access them on another page by indexing?
I've looked around alot and I've not found anything suggesting that this is possible.
Right now I'm using a single set of cookies to store info on a series of purchaces of the same type of item. I'm hoping to use session variables to replace the cookies.
Does anyone know for certain if this is not possible?
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.
I dump the entire recordset into an array:
If not rs.EOF Then
aEmp = rs.GetRows()
Contents of the array are in this order:
EmpID,EmpName,Indent,Sub_ID,Lft,Rgt,MgrID, LastName
This query sort on the basis of Lft and Rgt columns.
The name of the array is: aEmp.
My question here is how can I get only the LastName from the aEmp array into another array so that I can sort the names alphabetically and then display the employees in the alphabetical order.
Or is there is another way I could this by using the same array while keeping the lft and rgt sort of the query? If I sort based at the SQL query level, I can see the names sorted by the lft, rgt and lastname, but since the lastname is at the end of the sort list - it does not appear alphabetically.
can anyone tell me difference between environment variables and server variables.
View Replies View RelatedI want to create a new array called arrNames2 and copy contents of arrNames to arrNames2.
I then want to loop through my db and add more names (while going through the loop) to arrNames2. What is the best way to do this? Do I have to keep redim the array wehn I add more names?
I'm not sure how to best describe my problem, so a simple example should help explain things:
I have two arrays, called set1_data and set2_data
if I create a variable like so:
firstPart = "set1"
and then assign like this:
copyOfArray = firstPart & "_data"
how do I make copyOfArray reference the set1_array, as opposed to just a string "set1_array" which is what it's doing?
I've had a good rummage round ye olde Internet but couldn't find anything there must be a keyword or function to achieve this?!?

I have a page in my admin system where the user can edit products they
have added. The problem I am having is with Related Products. These are
all listed in a multiple list. What I need to do is have those selected

on the product edit page. Here is my post from another forum.

starts.
for counter = 0 to 1

Can someone help me understand why?
The problem is that in my 5 years of programming in various languages i have never really understood arrays (DUMB @$${lol})
What i want to do is offer an advanced search of a database table on my website. I currently offer the functionality so that the whole of the database can be viewed within the web page so that it doesn't need to be downloaded/need access to view it.
What i need to do is run a script that takes all of the column headings that i have and put them into an array. Then with the array i need to output each element into a drop down box.
Ok what I have is a little script which runs through my stock compares how many of one item we have compared to what we need and displays the out come.
What id like to do is make an array with the item name so lets say If how many is needed is greater then 0 then add the name of that consumable to an array and move on until the end.
Then I want to use the arry to display each consumable on an order form. Anyone have any idea how to do this in ASP or can give me any advice on a better way to do it?
I am doing the following:
Code:
dim n
n=4'ubound(arrsequences)

Microsoft VBScript compilation error '800a0402'
Expected integer constant
process.asp, line 33
dim arrproductNames(n)
How can I add something to an array, e.g

I have a form that has fields named Title1, Title2, and so on to title 12
I want to set up an array that goes through all the input feild values that I already put into variables such as Title1, Title2...so on. It then replaces ' with '' so the apostrophe can be entered into the database. So it:
Creates an array by looping through the variables that get the form feilds.
Then loops through the array and replaces the ' with '':
Title1=(Replace(Title2, "'", "''"))
I'm looking to make an admin page for a web photo gallery, and I need to make a drop down menu showing all files in a given directory that do not have comments in a database for the given filename.
I'm curious about the most efficient way to do this. I don't want to query the database separately for each file as this would be horribly inefficient. I'm thinking about two arrays, one containing all filenames in the photo directory, and one containing filenames from the database that have descriptions.

I have two recordsets that I want to populate within an array.
The array will always have two columns, but the number of rows is unknown (sometimes 2 rows other times 200 rows). I'm not too familiar working with arrays.
I want populate the array using a loop. How would I define and populate the array within loop so that I don't lose values and each new set of values are populated into the array through each iteration of the loop? Code:
for i = 2 to NOD
newdate = DateAdd("d", 1, newdate)
strdate = strdate & newdate & ", "
next
MyArray = split(strdate, ", ")
I have the above code written in one of my asp pages, the date array is splitted, but how do I get the first and last date assign to a variable.....
int min = MyArray(MyArray.Length-1)
int max = MyArray(0)
I got this code from the web, however it gives me an error:
Code:
Microsoft VBScript runtime error '800a01a8'
Object required: 'MyArray'
