This little sample program demonstrates how to make a treecontrol with checkboxes belonging to each item. Note that this sample was generated using MSVC++ 5. Should work with MSVC++ 6 as well. Note further that I used the style-constant TVS_CHECKBOXES, which is declarated in VC++5, but not commented. Downloads Download demo project – 23 Kb

CFlatPopupMenu One thing has always bothered me about web-style controls that pop up menus, and that’s the way that the menus don’t look as if they are owned by the control.

Have you noticed, however, that most of them are limited to scrolling the text either inside a textbox, or status bar? For […]

This article describes how to load a tree structure into MFC’s TreeCtrl class. The data members are loaded into it dynamically, and it’s very simple to change the whole structure of the tree. Each node of the tree holds a function pointer to a function to execute when double clicked. Here is the basic structure […]

Environment: VC6 SP3, NT4 SP3 This ActiveX control is intended to display a distribution graph of numerical datas. The datas are split among a set of constant intervals. The horizontal axis displays the interval values. The vertical axis shows the number of occurences (percentage) of numerical datas in each interval. Each data is combined with […]
