Please Richard a quick look at my previous post (also copied below)
"No, it still makes no sense. You add an extra column to your table and then you say you need to store information in extra rows. Choose one or the other."
I've added an extra ret column
rt_col->ColumnName = "Ret";
Then I need to fill the rows of this new column "Ret" based on the values held in "Population" column.
1st value of "Ret" should equal = log( 1st value of Population / 2nd value of Population)
2nd value of "Ret" = log (3rd value of Population / 4th value of Population)
ps: please let me reiterate that both "Ret" and "Population" are columns from the datable object dbdataset.
** in vba it will take me <3 minutes to perform it but I am stuck in c++ (part of the learning process I suppose ) Again thanks for the help
And once again, I repeat, I have already shown you how to fill these columns. You just iterate through the rows of your datatable inserting the values (however you calculate them) into the Ret column of each row.
First and foremost, sincere apologies for a naivety mainly attributable to inexperience Yet. I acknowledge that the code posted is perfectly fine. While adapting to my needs, performing the loop before the below piece of code has resulted in blank "Ret" columns, confused me, and triggered some skepticism.
Now all look fine, and I'd like to thank you very much for your assistance. I spent the weekend on this mater whereas it took you barely few minutes from your side to bring a concrete solution. Hence I am indeed impressed, and hope to become a day a c++ pundit like you so as to give back by helping others on forums too.
You will need to add some code to iterate through all the controls in the dialog. Using the location and dimensions of each item you can calculate the maximum width and height required. Use that information to resize the dialog window.

You haven't asked for help, you asked for a full solution.
If you want help, then you first need to do as much as possible by yourself, up to the point where you don't know how to proceed. Then tell us why you can't proceed and what, precisely, it is that you don't understand or don't know how to solve.
There's no point for us to provide a full fledged answer if we don't know what you already know - we might just be wasting our time telling you what you already know!
You may be unsure on how to start, maybe you believe if your design isn't perfect right from the start then you will ultimately fail. But that is not how software development works: software development never starts with a perfect design! Instead you start with what you think works best, and go on until you realize that you can't go on, or some detalis of your design are impractical. Then, based on what you've just learned, you correct your design. If all else fails, start new from scratch.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
To understand the SP's functionality, we recently took one of the device vendors SP's DLL for accessing their device and we were able to successfully communicate with their device using our windows application(Eclipse MINGW based).
