This class along with its associated ControlTemplate allow all TabItems to remain in the VisualTree without it being Sticky. It does this by keeping all TabItem content in the VisualTree but hides all inactive TabItem content, and only keeps the active TabItem content shown.

DoubleUtil uses fixed eps to provide fuzzy comparison functionality for doubles. Note that FP noise is a big problem and using any of these compare methods is not a complete solution, but rather the way to reduce the probability of repeating unnecessary work. Epsilon - more or less random, more or less small number. AreClose returns whether or not two doubles are "close". That is, whether or not they are within epsilon of each other. There are plenty of ways for this to return false even for numbers which are theoretically identical, so no code calling this should fail to work if this returns false. The first double to compare. The second double to compare. The result of the AreClose comparision. LessThan returns whether or not the first double is less than the second double. That is, whether or not the first is strictly less than *and* not within epsilon of the other number.

A mask that contains all the valid bits. SetWindowPos options If the calling thread and the thread that owns the window are attached to different input queues, the system posts the request to the thread that owns the window. This prevents the calling thread from blocking its execution while other threads process the request. Prevents generation of the WM_SYNCPAINT message. Draws a frame (defined in the window's class description) around the window. Applies new frame styles set using the SetWindowLong function. Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed. Hides the window. Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or non-topmost group (depending on the setting of the hWndInsertAfter parameter). Discards the entire contents of the client area. If this flag is not specified, the valid contents of the client area are saved and copied back into the client area after the window is sized or repositioned. Retains the current position (ignores X and Y parameters). Does not change the owner window's position in the Z order. Does not redraw changes. If this flag is set, no repainting of any kind occurs. This applies to the client area, the nonclient area (including the title bar and scroll bars), and any part of the parent window uncovered as a result of the window being moved. When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing. Same as the SWP_NOOWNERZORDER flag. Prevents the window from receiving the WM_WINDOWPOSCHANGING message. Retains the current size (ignores the cx and cy parameters). Retains the current Z order (ignores the hWndInsertAfter parameter).

Retrieves the show state and the restored, minimized, and maximized positions of the specified window. A handle to the window. A pointer to the WINDOWPLACEMENT structure that receives the show state and position information. Before calling GetWindowPlacement, set the length member to sizeof(WINDOWPLACEMENT). GetWindowPlacement fails if lpwndpl-> length is not set correctly. If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. Sets the show state and the restored, minimized, and maximized positions of the specified window. A handle to the window. A pointer to a WINDOWPLACEMENT structure that specifies the new show state and window positions. Before calling SetWindowPlacement, set the length member of the WINDOWPLACEMENT structure to sizeof(WINDOWPLACEMENT). SetWindowPlacement fails if the length member is not set correctly. If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. Retrieves the length, in characters, of the specified window's title bar text (if the window has a title bar). If the specified window is a control, the function retrieves the length of the text within the control. However, GetWindowTextLength cannot retrieve the length of the text of an edit control in another application. A handle to the window or control. If the function succeeds, the return value is the length, in characters, of the text. Under certain conditions, this value may actually be greater than the length of the text. For more information, see the following Remarks section. If the window has no text, the return value is zero. To get extended error information, call GetLastError. Copies the text of the specified window's title bar (if it has one) into a buffer. If the specified window is a control, the text of the control is copied. However, GetWindowText cannot retrieve the text of a control in another application. A handle to the window or control containing the text. The buffer that will receive the text. If the string is as long or longer than the buffer, the string is truncated and terminated with a null character. The maximum number of characters to copy to the buffer, including the null character. If the text exceeds this limit, it is truncated. If the function succeeds, the return value is the length, in characters, of the copied string, not including the terminating null character. If the window has no title bar or text, if the title bar is empty, or if the window or control handle is invalid, the return value is zero. To get extended error information, call GetLastError. This function cannot retrieve the text of an edit control in another application. The MonitorFromRect function retrieves a handle to the display monitor that has the largest area of intersection with a specified rectangle. Pointer to a RECT structure that specifies the rectangle of interest in virtual-screen coordinates Determines the function's return value if the rectangle does not intersect any display monitor If the rectangle intersects one or more display monitor rectangles, the return value is an HMONITOR handle to the display monitor that has the largest area of intersection with the rectangle. If the rectangle does not intersect a display monitor, the return value depends on the value of dwFlags. Loads an icon, cursor, animated cursor, or bitmap. Handle to the module of either a DLL or executable (.exe) that contains the image to be loaded Specifies the image to load Specifies the type of image to be loaded. Specifies the width, in pixels, of the icon or cursor Specifies the height, in pixels, of the icon or cursor This parameter can be one or more of the following values. If the function succeeds, the return value is the requested value.If the function fails, the return value is zero. To get extended error information, call GetLastError. Stop flashing. The system restores the window to its original state. Flash the window caption Flash the taskbar button. Flash both the window caption and taskbar button. This is equivalent to setting the FLASHW_CAPTION | FLASHW_TRAY flags. Flash continuously, until the FLASHW_STOP flag is set. Flash continuously until the window comes to the foreground.

TreatAsSafe - it would be ok to expose this information - DPI in partial trust Invalidates the rectangle or region that you specify in lprcUpdate or hrgnUpdate. You can set only one of these parameters to a non-NULL value. If both are NULL, RDW_INVALIDATE invalidates the entire window. Causes the OS to post a WM_PAINT message to the window regardless of whether a portion of the window is invalid. Causes the window to receive a WM_ERASEBKGND message when the window is repainted. Specify this value in combination with the RDW_INVALIDATE value; otherwise, RDW_ERASE has no effect. Validates the rectangle or region that you specify in lprcUpdate or hrgnUpdate. You can set only one of these parameters to a non-NULL value. If both are NULL, RDW_VALIDATE validates the entire window. This value does not affect internal WM_PAINT messages. Suppresses any pending WM_ERASEBKGND messages. Excludes child windows, if any, from the repainting operation. Includes child windows, if any, in the repainting operation.

Creates a new instance. Inheritors should provide a factory for setting up the path data index (per icon kind). The factory will only be utilized once, across all closed instances (first instantiation wins). Identifies the dependency property. Gets or sets the icon to display. Identifies the dependency property. Gets the icon path data for the current . This custom popup can be used by validation error templates or something else. It provides some additional nice features: - repositioning if host-window size or location changed - repositioning if host-window gets maximized and vice versa - it's only topmost if the host-window is activated Identifies the dependency property. Gets or sets if the popup can be closed by left mouse button down. Identifies the dependency property. Gets or sets whether if the Popup should be always on top. Causes the popup to update it's position according to it's current settings. SetWindowPos options AddValueChanged of dependency property descriptor results in memory leak as you already know. So, as described here, you can create custom class PropertyChangeNotifier to listen to any dependency property changes. This class takes advantage of the fact that bindings use weak references to manage associations so the class will not root the object who property changes it is watching. It also uses a WeakReference to maintain a reference to the object whose property it is watching without rooting that object. In this way, you can maintain a collection of these objects so that you can unhook the property change later without worrying about that collection rooting the object whose values you are watching. Complete implementation can be found here: http://agsmith.wordpress.com/2008/04/07/propertydescriptor-addvaluechanged-alternative/ Identifies the dependency property. Gets or sets the value of the watched property.

Works around an issue in the XamlReader. Without this fix the XamlReader would not be able to read the XAML we produced earlier because it does not know where to look for the types. The real issue is that we can't use the full namespace, with assembly hint, at compile time of the original project because said assembly does not yet exist and would cause a compile time error. Hence we have to use this workaround to enable both. The issue The fixed version of .
