What kind of data ? The representation is more or less always dependent of the data.
Is it text/numerical values ? is it some kind of numerical data that you need to graph them ?
you can use a CListBox or a CListCtrl to display data in a list or tabular fashion (or if needing a "spreadshet" type control, look for (
MFC Grid control 2.27[
^] )
you can use a CTreelCtrl for hierarchical data
If none of the existing controls suit you, you can look for a 3rd party UI control.
If no 3rd party control work for you, you will have to design and code it yourself based on your requirements and specifications.
Most controls start from a CWnd derived class.
Good luck.
