<h2>

|
Overview
|
|
</h2>
|
|
<p>
|
|
Ookii.Dialogs is a class library for .Net applications providing several common dialogs. Included are classes for
|
|
task dialogs, credential dialogs, progress dialogs, input dialogs, and common file dialogs.
|
|
</p>
|
|
<p>
|
|
This package contains two class libraries: Ookii.Dialogs.dll for use with Windows Forms, and Ookii.Dialogs.Wpf.dll
|
|
for use with Windows Presentation Foundation. The classes inside are pretty much identical; only the input dialog
|
|
is not available for WPF. Some additional utility classes for Windows Forms are provided that are not available for
|
|
WPF, see below for details.
|
|
</p>
|
|
<p>
|
|
Ookii.Dialogs requires the <a href="http://www.ookii.org/link.ashx?id=NetFramework35">Microsoft .Net Framework 3.5 SP1</a>.
|
|
The included source code is intended for use in Visual Studio 2008.
|
|
</p>
|
|
<p>
|
|
The included sample applications Ookii.Dialogs.Sample.exe and Ookii.Dialogs.Sample.Wpf.exe demonstrate the dialogs
|
|
for Windows Forms and WPF respectively. View the source of these applications to see how to use the dialogs.
|
|
</p>
|
|
<p>
|
|
Full reference documentation for the class library is available in the <a href="Ookii.Dialogs.chm">included help file</a>.
|
|
</p>

<h2>
|
|
Included dialogs
|
|
</h2>
|
|
<h3>
|
|
Task dialog
|
|
</h3>
|
|
<p>
|
|
<a href="http://msdn.microsoft.com/en-us/library/bb760441(VS.85).aspx">Task dialogs</a> are a new type of dialog
|
|
first introduced in Windows Vista. They provide a superset of the message box functionality.
|
|
</p>
|
|
<p>
|
|
<img src="images/taskdialog.png" alt="A task dialog" />
|
|
</p>
|
|
<p>
|
|
The Ookii.Dialogs.TaskDialog (for Windows Forms) and the Ookii.Dialogs.Wpf.TaskDialog (for WPF) classes provide access
|
|
to the task dialog functionality. The TaskDialog class inherits from System.ComponentModel.Component and offers full
|
|
support for the Windows Forms designer and component designer of Visual Studio 2008.
|
|
</p>
|
|
<p>
|
|
The TaskDialog class requires Windows Vista or a later version of Windows. Windows XP is not supported. Note that it is
|
|
safe to instantiate the TaskDialog class and set any of its properties; only when the dialog is shown will a NotSupportedException
|
|
be thrown on unsupported operating systems.
|
|
</p>
|
|
<h3>
|
|
Progress dialog
|
|
</h3>
|
|
<p>
|
|
Progress dialogs are a common dialog to show progress during operations that may take a long time. They are used
|
|
extensively in the Windows shell, and an API has been available since Windows 2000.
|
|
</p>
|
|
<p>
|
|
<img src="images/progressdialog.png" alt="A progress dialog as it appears on Windows Vista and later" />
|
|
</p>
|
|
<p>
|
|
The Ookii.Dialogs.ProgressDialog (for Windows Forms) and the Ookii.Dialogs.Wpf.ProgressDialog (for WPF) classes provide
|
|
a wrapper for the Windows progress dialog API. The ProgressDialog class inherits from System.ComponentModel.Component and offers full
|
|
support for the Windows Forms designer and component designer of Visual Studio 2008. The ProgressDialog class resembles
|
|
the System.ComponentModel.BackgroundWorker class and can be used in much the same way as that class.
|
|
</p>
|
|
<p>
|
|
The progress dialog's behaviour of the ShowDialog function is slightly different than that of other .Net dialogs; please
|
|
read the reference documentation for more information. It is recommended to use a non-modal dialog with the Show function.
|
|
</p>
|
|
<p>
|
|
The ProgressDialog class is supported on Windows XP and later versions of Windows. However, the progress dialog has a very different
|
|
appearance on Windows Vista and later (the image above shows the Vista version), so it is recommended to test on both
|
|
operating systems to see if it appears to your satisfaction.
|
|
</p>
|
|
<p>
|
|
When using Windows 7, the ProgressDialog class automatically provides progress notification in the application's task bar
|
|
button.
|
|
</p>
|
|
<h3>
|
|
Credential dialog
|
|
</h3>
|
|
<p>
|
|
The Ookii.Dialogs.CredentialDialog (for Windows Forms) and the Ookii.Dialogs.Wpf.CredentialDialog (for WPF) classes provide
|
|
wrappers for the CredUI functionality first introduced in Windows XP. This class provides functionality for saving and
|
|
retrieving generic credentials, as well as displaying the credential UI dialog. This class does not support all functionality
|
|
of CredUI; only generic credentials are supported, thing such as domain credentials or alternative authentication
|
|
providers (e.g. smart cards or biometric devices) are not supported.
|
|
</p>
|
|
<p>
|
|
<img src="images/credentialdialog.png" alt="A credential dialog as it appears on Windows Vista and later" />
|
|
</p>
|
|
<p>
|
|
The CredentialDialog class inherits from System.ComponentModel.Component and offers full
|
|
support for the Windows Forms designer and component designer of Visual Studio 2008.
|
|
</p>
|
|
<p>
|
|
On Windows XP, the CredentialDialog class will use the CredUIPromptForCredentials function to show the dialog;
|
|
on Windows Vista and later, the CredUIPromptForWindowsCredentials function is used instead to show the new dialog
|
|
introduced with Windows Vista. Because of the difference in appearance in the two versions (the image above shows
|
|
the Vista version), it is recommended to test on both operating systems to see if it appears to your satisfaction.
|
|
</p>
|
|
<h3>
|
|
Input dialog
|
|
</h3>
|
|
<p>
|
|
The input dialog is a dialog that can be used to prompt the user for a single piece of text. Its functionality
|
|
is reminiscent of the Visual Basic InputBox function, only with a cleaner API and UI.
|
|
</p>
|
|
<p>
|
|
<img src="images/inputdialog.png" alt="An input dialog as it appears on Windows Vista and later" />
|
|
</p>
|
|
<p>
|
|
The Ookii.Dialogs.InputDialog class provides the input dialog functionality for Windows Forms. This class is not
|
|
available for WPF.
|
|
</p>
|
|
<p>
|
|
Unlike the other classes in this package, this class is not a wrapper for any existing API; the dialog uses
|
|
a custom implementation in Windows Forms. This dialog is supported on Windows XP and later versions of windows;
|
|
on Windows Vista and later, the visual styles API is used to draw the dialog to mimic the appearance of task dialogs,
|
|
as shown in the image above.
|
|
</p>
|
|
<p>
|
|
The InputDialog class inherits from System.ComponentModel.Component and offers full
|
|
support for the Windows Forms designer and component designer of Visual Studio 2008.
|
|
</p>
|
|
<h3>
|
|
Vista-style common file dialogs
|
|
</h3>
|
|
<p>
|
|
Windows Vista introduced a new style of common file dialogs. As of .Net 3.5 SP1, the Windows Forms OpenFileDialog and
|
|
SaveFileDialog class will automatically use the new style under most circumstances; however, some settings (such
|
|
as setting ShowReadOnly to true) still cause it to revert to the old dialog. The FolderBrowserDialog still uses the
|
|
old style. In WPF, the Microsoft.Win32.OpenFileDialog and SaveFileDialog classes still use the old style dialogs,
|
|
and a folder browser dialog is not provided at all.
|
|
</p>
|
|
<p>
|
|
<img src="images/folderbrowserdialog.png" alt="The Vista-style folder browser dialog on Windows 7" />
|
|
</p>
|
|
<p>
|
|
The Ookii.Dialogs.VistaOpenFileDialog, Ookii.Dialogs.VistaSaveFileDialog and Ookii.Dialogs.VistaFolderBrowserDialog
|
|
provide these dialogs for Windows Forms (note that in the case of the OpenFileDialog and SaveFileDialog it is
|
|
recommended to use the built-in .Net classes unless you hit one of the scenarios where those classes use the old
|
|
dialogs). The Ookii.Dialogs.Wpf.VistaOpenFileDialog, Ookii.Dialogs.Wpf.VistaSaveFileDialog and Ookii.Dialogs.Wpf.VistaFolderBrowserDialog
|
|
classes provide the same functionality for WPF.
|
|
</p>
|
|
<p>
|
|
The classes have been designed to resemble the original Windows Forms and WPF classes to make it easy to switch.
|
|
When the classes are used on Windows XP, they will automatically fall back to the old style dialog; this is also
|
|
true for the VistaFolderBrowserDialog on WPF; that class provides a complete implementation of a folder browser
|
|
dialog for WPF, old as well as new style.
|
|
</p>
|
|
<p>
|
|
The Vista-style file and folder dialogs classes for Windows Forms inherit from System.ComponentModel.Component and offer full
|
|
support for the Windows Forms designer and component designer of Visual Studio 2008.
|
|
</p>
|
|
<h2>
|
|
Additional functionality for Windows Forms
|
|
</h2>
|
|
<p>
|
|
Three additional classes are provided for Windows Forms only, in the Ookii.Dialogs library. These classes are used to
|
|
support the InputDialog (with the exception of the Aero glass functionality, which the InputDialog does not use) but
|
|
are made public for your convenience.
|
|
</p>
|
|
<p>
|
|
The AdditionalVisualStyleElements class provides some visual style elements used by task dialogs on Windows Vista and later.
|
|
</p>
|
|
<p>
|
|
The Glass class provides functionality for extending Aero glass into the client area of a window on Windows Vista and later,
|
|
and for drawing text on a glass surface.
|
|
</p>
|
|
<p>
|
|
The ExtendedForm class serves as an alternative base class for forms, and provides functionality to automatically use the
|
|
system font (e.g. Tahoma on XP and Segoe UI on Vista and later), and easy access to some of the functionality of the Glass
|
|
class.
