C# Class SevenSoftware.Windows.Dialogs.TaskDialog.NativeTaskDialog

Encapsulates the native logic required to create, configure, and show a TaskDialog, via the TaskDialogIndirect() Win32 function.

A new instance of this class should be created for each messagebox show, as the HWNDs for TaskDialogs do not remain constant across calls to TaskDialogIndirect.

Méthode	Description
Dispose ( ) : void	Finalizes an instance of the NativeTaskDialog class.

Méthode	Description
Dispose ( bool disposing ) : void	Releases unmanaged and - optionally - managed resources.

Private Methods

Méthode	Description
AllocateAndMarshalButtons ( ICollection buttons ) : IntPtr	Allocates and marshals buttons.
AssertCurrentlyShowing ( ) : void	Show debug message when the native dialog is showing.
DialogProc ( IntPtr windowHandle, uint message, IntPtr parameter, IntPtr parameterLength, IntPtr referenceData ) : int	Processes dialog messages.
FreeOldString ( TaskDialogElements element ) : void	Frees the old string.
HandleButtonClick ( int id ) : int	Once the task dialog HWND is open, we need to send additional messages to configure it.
HandleHelpInvocation ( ) : int	Handles the help invocation.
HandleHyperlinkClick ( IntPtr reference ) : int	Handles the hyperlink click.
HandleRadioButtonClick ( int id ) : int	Handles the radio button click.
HandleTick ( int ticks ) : int	Handles timer ticks.
IsOptionSet ( TaskDialogOptions flag ) : bool	Determines whether the options are set for the dialog
MakeLongLongParam ( int a, int b ) : long	Makes a Long parameter.
MakeNewString ( string text, TaskDialogElements element ) : IntPtr	Allocates a new string on the unmanaged heap, and stores the pointer so we can free it later.
MarshalDialogControlStructs ( ) : void	Checks to see if the given element already has an updated string, and if so, frees it. This is done in preparation for a call to MakeNewString(), to prevent leaks from multiple updates calls on the same element within a single native dialog lifetime. Builds the actual configuration that the NativeTaskDialog (and underlying Win32 API) expects, by parsing the various control lists, marshaling to the unmanaged heap, etc.
NativeClose ( TaskDialogResult result ) : void	The new task dialog does not support the existing Win32 functions for closing (e.g. EndDialog()); instead, a "click button" message is sent. In this case, we're abstracting out to say that the `TaskDialog` consumer can simply call "Close" and we'll "click" the cancel button. .
NativeShow ( ) : void	Shows the native dialog.
NativeTaskDialog ( NativeTaskDialogSettings settings, TaskDialog outerDialog ) : System	Initializes a new instance of the NativeTaskDialog class.
PerformDialogCleanup ( ) : int	Performs the dialog cleanup.
PerformDialogInitialization ( ) : int	Performs the dialog initialization.
SendMessageHelper ( TaskDialogMessages message, int parameter, long parameterLength ) : int	Sends a message to the dialog.
UpdateButtonEnabled ( int buttonId, bool enabled ) : void	Updates the button enabled.
UpdateCheckBoxChecked ( bool isChecked ) : void	Updates the check box checked.
UpdateElevationIcon ( int buttonId, bool showIcon ) : void	Updates the elevation icon.
UpdateExpandedText ( string expandedText ) : void	Updates the expanded text.
UpdateFooterIcon ( TaskDialogStandardIcon footerIcon ) : void	Updates the footer icon.
UpdateFooterText ( string footerText ) : void	Updates the footer text.
UpdateIconCore ( TaskDialogStandardIcon icon, TaskDialogIconElement element ) : void	Updates the icon.
UpdateInstruction ( string instruction ) : void	Updates the instruction.
UpdateMainIcon ( TaskDialogStandardIcon mainIcon ) : void	Updates the main icon.
UpdateProgressBarRange ( ) : void	Updates the progress bar range.
UpdateProgressBarState ( TaskDialogProgressBarState state ) : void	Updates the state of the progress bar.
UpdateProgressBarValue ( int i ) : void	Updates the progress bar value.
UpdateRadioButtonEnabled ( int buttonId, bool enabled ) : void	Update the radio button when enabled has changed.
UpdateText ( string text ) : void	Updates the content text.
UpdateTextCore ( string text, TaskDialogElements element ) : void	Updates the text.
