>>>Nope. Won't work. ColumnOrder values do not have to be contiguous. That is, columnorder values can be 1,5,12,19; all that happens is that VFP displays the columns in that order. The absolute values are not used, just the values relative to one another.

>>>Thanks
>>What ? Reread the code. Of course columnorders need not be in order otherwise just using this.columns(this.activecolumn) would be sufficient. This method finds original columns collection index. That is : If you have columns named Column1, Column2..ColumnN, put this code to ARCC and add and textbox control named text1 and mix their order anyway on the fly :
LPARAMETERS nColIndex
>>local ix

>>             ThisForm.txtbox1.value = .columns(ix).name

>>	endif
>>  endfor
>>endwith
This at least works in VFP5 and part of my grid class for the same purpose. I just got VS6 package and don't know if something has changed yet(hope not).

>Lets do an example. I have three columns named Column1 with columnorder = 6, column2 with columnorder = 4, and column3 with columnorder = 56. Silly, but you can do this. The columns will appear on the screen in the order column2, column1 and columnn3.

Aha, extra special case :) Then first collect columnorders into an array, sort the array, use activecolumn as an index to array.
