Sorting 3 columns in a 2 dimension array
 

Hello ...

I would like to sort a 3-column combo box list; ordered by Column1
then by Column2 then by Column3.

Have looked at Tom Oglviy's dialogue with Tim Zych (Nov 5, 2002), but
am not sure how to scale the VBA code to accomplish my task.

Would appreciate any help.

John

Sorting 3 columns in a 2 dimension array
 

John,
Just to make sure of the circumstances...
The sort should be accomplished before loading the combobox.
If you have data on a worksheet, then use the VBA Sort Method
to sort the data and then load the combobox.
If you have your data in an array and not on a worksheet then
an array sort routine would be applicable.

Sorting 3 columns in a 2 dimension array
 

With a little help from the Internet world, I have a working solution.

For those interested, go to
http://www.excelwiki.com/VBA/Arrays-BubbleSort for the following
snippet:

SortColumn1=0
SortColumn2=3 '<--changed to 1
SortColumn3=5 '<--changed to 2
For i = LBound(ArrayName, 1) To UBound(ArrayName, 1) - 1
For j = LBound(ArrayName, 1) To UBound(ArrayName, 1) - 1
Condition1=ArrayName(j, SortColumn1) ArrayName(j + 1,
SortColumn1)
Condition2=ArrayName(j, SortColumn1) = ArrayName(j + 1,
SortColumn1) and _
ArrayName(j, SortColumn2) ArrayName(j + 1,
SortColumn2)
Condition3=ArrayName(j, SortColumn1) = ArrayName(j + 1,
SortColumn1) and _
ArrayName(j, SortColumn2) = ArrayName(j + 1,
SortColumn2) and _
ArrayName(j, SortColumn3) ArrayName(j + 1,
SortColumn3)

If Condition1 or Condition2 or Condition3 Then
For y = LBound(ArrayName, 2) To UBound(ArrayName, 2)
t = ArrayName(j, y)
ArrayName(j, y) = ArrayName(j + 1, y)
ArrayName(j + 1, y) = t
Next y
End If
Next
Next

This seems to be both scalable and flexible.

Thx ... John

John,
My modified version of the code below is much faster,
however, it is still very slow on large arrays.
