// Declaration of the CTaskDialog class
|
|
|
|
// A task dialog is a dialog box that can be used to display information
|
|
// and receive simple input from the user. Like a message box, it is
|
|
// formatted by the operating system according to parameters you set.
|
|
// However, a task dialog has many more features than a message box.
|
|
|
|
// NOTES:
|
|
// Task Dialogs are only supported on Windows Vista and above.
|
|
// Task Dialogs require XP themes enabled (use version 6 of Common Controls)
|
|
// Task Dialogs are always modal.
