Change events puzzle me...

I have been learning vba now for about 1 year and the light is slowly going on but not burning bright at all...so I am still very "beginner-ish" but am getting better.

In that time I have gotten to know how to handle ranges and rows quite well per my previous lot of questions.

Having said that I have come to somewhat of a cross roads with my project and I have to wonder is there a better way.

Having said that I am going to describe in detail what I am trying to do and see if there is indeed a better way.

So without further adieu here is what I have.

I have a  data set that dynamically changing all of the time.

Let's say that there are 1000 rows.

What I want to know is:

Let's say that there is a change in the row 24, column G.  Let's say that in Column G there is a simple formula that says if e24>f24 then 1, otherwise "".  Well, e24 suddenly = 9 and there is nothing in f24 so G24 = 1.  This is the kick off to the change event.   The rest of the code after this I am handle.  I even have the code needed to "reset" G24 for the next time.

What I do not need is for any other row to be affected whatsoever.  I am only interested in row 24 because G24 fired.

Now if G56, which also has a similar formula to G24 (all cells in column G do between G10:G1010) then I would like to see a change for only things in row 56.

...and so on down the whole range.

What I DO NOT WANT IS A LOOP.  THEY TAKE TOO LONG PLEASE AND THANK YOU.

I was playing around with:

Range("G10:G1010").specialcells(xlCellsTypeFormula, 2).Calculate = "1"

...but I am not sure how to manipulate it further than that.

So in short, I need a "change event" or "calculate event" or something else that is lightning fast for these ranges.   What ever happen in that particular row on affects that particular row and the rest of the range is unaffected.

Any help or illumination on this problem would be much appreciated.

thanks,

Sorry your post is too confusing and long. I read it twice and lost between what is and what should and what you want.

Can you in 1 sentence ask a question on what exactly you want ?

the Workbook_SheetChange event provides a Target range property that you can interrogate to get the cell that has changed.

There is also a Worksheet_Change event, attached to each worksheet but often easier to trap the workbook event and then filter out the sheets that need to be checked.

``````Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
MsgBox "chaneg - " & Target.Address
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)

End Sub
``````
note that only cells that get changed 'manually' trigger the event. Cells that change due to formula do not trigger event.

That if the event is a Calculate event then YES [Cells that change due to formula WILL trigger event.]

Gowflow,

You are working on my other solution.

In one sentence:  In my other solution,....is there an overall better way to accomplish what I am trying to do there?   (All of this will be automated, that test10 sheet is just an example).

thanks!

So in my other sheet I have something that will automatically make a change event.   Not manually.

But is there a different way all together?  Willing to try new options!

thanks!

Thank you for the appreciation. You may put your comments in the other question that  I will keep open this one will not be monitored.
