About Trackbars
Trackbars are useful when you want the user to select a discrete value or a
set of consecutive values in a range. For example, you might use a trackbar to
allow the user to set the repeat rate of the keyboard by moving the slider to a
given tick mark.
The slider in a trackbar moves in increments that you specify when you create
it. For example, if you specify that the trackbar should have a range of five,
the slider can only occupy six positions: a position at the left side of the
trackbar and one position for each increment in the range. Typically, each of
these positions is identified by a tick mark.
You create a trackbar by using the CreateWindowEx function, specifying the TRACKBAR_CLASS window class. Once you have created a
trackbar, you can use trackbar messages to change many of its properties.
Changes that you can make include setting the minimum and maximum positions for the
slider, drawing tick marks, setting a selection range, and repositioning the
slider.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
