|
|
* do anything except show a dialog box and returning a value based upon the value chosen. That
|
|
* means that any code that calls the function has to execute the chosen action (shut down,
|
|
* restart, etc.).
|
|
* - When this function is called in Windows XP, it shows the classic dialog box regardless if
|
|
* SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\LogonType is enabled or not.
|
|
* - When the Help button is pushed, it sends the same return value as IDCANCEL (0x00), but
|
|
* at the same time, it calls the help file directly from the dialog box.
|
|
* - When the dialog is created, it doesn't disable all other input from the other windows.
|
|
* This is done elsewhere. When running the function ShellShutdownDialog() from XP/2K3, if the user clicks
|
|
* out of the window, it automatically closes itself.
|
|
* - The parameter, lpUsername never seems to be used when calling the function from Windows XP. Either
|
|
* it was a parameter that was never used in the final version before release, or it has a use that

|
* is currently not known.
