Comparing Two Arrays
How do you compare the content of two arrays
I have one array - aLinkCat (contents: LinkID and CategoryID) and another array called aCat (contents: CategoryID) I want to determine when the value in aLinkCat (CategoryID) matches the value in aCat (CatagoryID, CategoryName), so that I can indicate that categoryid has been selected. I need to compare the second element in the first array with the first element in the second array. Thanks in advance! Last edited by aspnewbie : February 11th, 2003 at 01:00 PM.

I got it to work eventually, although it's not pretty.
Code:
set oRS = GetRS(sConn, "usp_GetLinkCategories @lid =" & iLID)
sCategorySelect = ""
while not (oRS.eof or oRS.bof)
sCategorySelect = sCategorySelect+ cstr(oRS("CategoryID")) + ","
oRS.movenext
wend
if "" & sCategorySelect <>"" then
sCategorySelect = left(sCategorySelect,len(sCategorySelect)-1)
End if
'Response.Write sCategorySelect
y= split(sCategorySelect,",")
aCat = GetArrRS(sConn,"usp_ListCategories")
sCategorySelect = "<Select name=""sCategorySelect"" multiple>"
If IsArray(aCat) then
for j = 0 to Ubound(aCat, 2)
sCategorySelect = sCategorySelect & "<option value=""" & aCat(0, j) & """"
for i = 0 to Ubound(y)
if cint(y(i))=aCat(0, j) then
sCategorySelect = sCategorySelect + " selected "
exit for
End if
Next
sCategorySelect = sCategorySelect + ">" + aCat(1, j)
sCategorySelect = sCategorySelect & "</option>"
Next
End if
sCategorySelect= sCategorySelect & "</select>"
Presumably there is a shorter way. If anybody has any better suggestions, I'm all ears!
