Context-Sensitive Help
All common dialog boxes provide context-sensitive Help for the standard
controls of the dialog box. The user can display Help for individual controls by any
of the following methods:
- Selecting the control and pressing the F1 key
- Clicking the ? button in the title bar and subsequently clicking on a control
- Clicking the right mouse button over a control
If you customize a dialog box by adding new controls, you must also extend
help support for these controls by processing requests for help in the hook
procedure. The hook procedure receives the following messages when the user requests
help.
User Action
| Message
| The user clicked the right mouse button over a control.
| WM_CONTEXTMENU
| The user pressed the F1 key.
| WM_HELP
| The user clicked the ? button in the title bar and then clicked on a control.
| WM_HELP
|
You should process these messages for the controls you have added, but let the
default dialog box procedure process the messages for the standard controls.
For more information about how to process these messages, see the Help overview.

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 » |
