Remove Duplicates From Array

I am pulling some records out of a database which have a Description field containing several words, and storing this information in an array using GetRows().

Then using a for-next loop I am going through these records and using the Split() function to get the first word of the Description and then adding it as an option to a dropdown list.

The problem is I get lots of duplicates in the drop down because lots of the descriptions have the same first word. Using DISTINCT in the SQL statement won't help much because at that stage the descriptions arent the same. Code:

How To Check Is A Value Exists In An Array?

I populate a recordset and dump it into an array. How can I check if a value exist in the array? I want to check if the c_Member_mgr has a particular value or not?

Dim rs2
set rs2 = Server.CreateObject("ADODB.Recordset")
rs2.open sub_Emp_Source, Conn

Dim aSubordinates

If not rs2.EOF then

aSubordinates = rs2.GetRows()

'Close Recordset to use the new array with the 2 columns data
rs2.Close()
set rs2 = Nothing

'Declare Constants for the above SQL columns for better readability
'Use these Constants instead of referring to the array numeric indexes
Const c_Member_Mgr = 0
Const c_Subordinate = 1
Const c_EmpID = 3
Const c_EmpName = 4

Avoiding Duplicates

I have a string value which has the bellow content.

Dim aString as string

aString = "1,2,4,2,2"

where aString is a parameter set dynamically based on the user loggin into the system. Now All I want to do is to eliminate the duplicates. ( In this case I need to keep only one "2" and remove the remaining "2" , so my final string should be "1,2,4" ).

How could I do that. I was thinking of an array, but the issue is, If the "aString" is empty I believe array will return a error. So any other way of doing ?. Or simple asp functions which will eliminate this.

Checking For Duplicates

A member logs on and enters a record, if one already exists for that date, then they get a message saying so. If not the record is added and some text is displayed. But it still allows me to enter records even if one already exists! is it because I am storing my dates as strings? Code:

Remove Duplicates

I have an array like this:Code:

arrColour = split("blue,blue,green,red,purple,blue,green,yellow",",")

Rebuilding Of An Array From An Existing Array

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.

Array Integers Vs Array Variables

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

Log Check In ASP

I am working on a website that requires a login before accessing an appointment book application written in ASP.Basically what I want to do is when the customer first clicks on "appointment_book" link, it takes them to the registration form. After they are registered, It will then redirect them to the actual application.
I also want the same thing to happen when a customer clicks on the login link. I want them to login, then get redirected to the appointment_book.
at the moment the customer click on the registratration link and it shows them the registration form, they are then automatically logged in after registration. However, when I click on the Appointment_book link again, it brings me back to registration form. How can I have the link always point to the appointment book after they are registered or logged in?

I'm trying to guard against SQL injection, but I have an ID number being embedded into a querystring for MSSQL table selection.

Is it good enough just to check if the querystring value is an int, if so could you quickly remind me how to check that. In PHP we use is_numeric or is_int.
