C++ Equivaliant of a FlexGrid

Does C++ have a control like VB's FlexGrid? If so can someone post the Const for the 'Events' of it or the header file.

In VB I am trying to capture when TextMatrix is used or AddLine and I hooked it and found that it receives 2 Messages 15 and 20 and 1 of them has a wParam but I can't figure out what the info is supposed to be. So I was thinking if I could look in the header file maybe I could see something that helps. I hope this makes sense (probably not). I have C++ but at home not at work where I am.

Well I found that 15 is WM_PAINT so it is painting and then whatever 20 is. Hmmm.

About your answer:
WM_PAINT = 15
in this message you have wParam = 0 and lParam = 0

WM_ERASEBKGND = 20

in this message you have wParam = FlexGrid HDC and lParam = 0

you get 2 messages together because windows paint with 2 steps:
1º - Send 20 (erasebackground) with wParam = HDC
2º - Send 15 (Paint) with no more information

C++ does not "have" controls. C++ itself has no graphical capabilities at all, and actually not even any other I/O.
Basic I/O is provided through the standard library.
Graphical abilites are provided through special APIs.

Anyway, you can access the FlexGrid control through C++, but it is rather tedious.

You cannot really hook into it anyway. The two messages just mean that the control is redrawing itself.
