Hello every one,
this is about an array of string and may be have done several time
before but i need it and wasnt able to find it so here is the problem

i have an array of strings with contains words and i want a distinct
list of array with the count of each number repeat i.e how many time
it exist in the array and the final result should be sorted according
to the number of repeat from hight to low .
for example

thearray="32a,7s,5a,29s,20,29s,32a,8,5a,32a,32a,32 a"

the result should be
32a
29s
5a
7s
20
8

i have this code which take out all the duplicate values and print the
distinct values

function RemCDups(byVal thearray)

Dim element,element2,k,i,j
dim newArray()
redim newArray(0)

for i = 0 to ubound(thearray)

element = thearray(i)
element2 = "false"

for j = i + 1 to Ubound(thearray)
if theArray(j) = element then
element2 = "true"
end if
next

if element2 = "false" then
redim preserve newArray(Ubound(newArray)+1)
newArray(k) = theArray(i)
k = k + 1
end if
next

RemCDups = newArray
end function

but i want to modify it to do the sort according to the count of each
element from high to low

thanks.

regards
NIQ

So you have succeded finding the values and putting 'em into an array and
now you want to order the array?

for j = 1 to ubound(array)
for i = 0 to ubound(array)
if not i=ubound(array)
if array(i)<array(i+1) then
temp=array(i)
array(i)=array(i+1)
array(i+1)=temp
end if
end if
next
next

I hope i've written the algorithem currect... this is the simplest way to
order an array.
you can also use JS.

NiQ...

I took a different approach and chose to use a dictionary.

I took your string and split it to create an array of elements.

I took the elements of the array and created a dictionary but only to add
unique keys so the result was 6 keys. I then created another dictionary,
comparing with the first dictionary keys to find the duplicates and then
incremented the value of the items. After that I used a dictionary sort I
found at Microsoft and modified it so I could pass the order to return the
results.

This is my solution. There is a link on the page to view the source.

hi ronald
thanks again for your great help , i am just having a little problem
when i increase the number of one exisitence more than 10 then it
sorts it verz strangly i want to sort on the number of occourences
with the code u wrote can u try this array
thearray = "32a,7s,5a,29s,20,29s,32a,8,5a,32a,32a,32a,32a,32a ,32a,32a,32a,32a,32a,32a"

the result will be something like this
2=29s
2=5a
13=32a
1=8
1=20
1=7s

when it should be
13=32a
2=29s
2=5a
1=8
1=20
1=7s

please let me know how i can fix it .

best regards
NIQ

This is the correct alpha (string) sort order.

You want a numeric sort order so you need to convert the strings to numbers
before doing the sort. This is the line that needs changing:

If StrComp(strDict(X,intSort),strDict(Y,intSort),vbTe xtCompare) > 0 Then

Change it to
If CInt(strDict(X,intSort)) > CInt(strDict(Y,intSort)) Then

What if a date comparison is needed ... ? Or Doubles?

I changed the whole function so you can pass text or numeric so the sort
routine could be reusable in the future.

hi Roland,
there is something wrong . it take the count sort as character i.e if
the

occourance is 102 then it will come with all 1's then all 2's

thearray="32a,7s,5a,29s,20,29s,32a,8,5a,32a,32a,32 a,32a,32a,32a,32a,32a,32a,32a,32a,32a"

try with this and you will see what i mean .

i tried a little but can get it work . may be you can help

thanks a lot

I did and it works fine. Perhaps you missed my other post following Bob's
first post on this thread. The example is running with the above value.
