This method raised the BalloonTipClosed event. This method raised the BalloonTipShown event. This method actually raises the Click event. Inheriting classes should override this if they wish to be notified of a Click event. (This is far preferable to actually adding an event handler.) They should not, however, forget to call base.onClick(e); before exiting, to ensure that other recipients do actually get the event. Inheriting classes should override this method to handle this event. Call base.onDoubleClick to send this event to any registered event listeners.

The system enforces minimum and maximum timeout values. Timeout values that are too large are set to the maximum value and values that are too small default to the minimum value. The operating system's default minimum and maximum timeout values are 10 seconds and 30 seconds, respectively. No more than one balloon ToolTip at at time is displayed for the taskbar. If an application attempts to display a ToolTip when one is already being displayed, the ToolTip will not appear until the existing balloon ToolTip has been visible for at least the system minimum timeout value. For example, a balloon ToolTip with timeout set to 30 seconds has been visible for seven seconds when another application attempts to display a balloon ToolTip. If the system minimum timeout is ten seconds, the first ToolTip displays for an additional three seconds before being replaced by the second ToolTip. Displays a balloon tooltip in the taskbar with the specified title, text, and icon for a duration of the specified timeout value. The system enforces minimum and maximum timeout values. Timeout values that are too large are set to the maximum value and values that are too small default to the minimum value.

Updates the icon in the system tray. Handles the mouse-down event Handles the mouse-move event Handles the mouse-up event Defines a placeholder window that the NotifyIcon is attached to. Create a new NotifyIcon, and bind the window to the NotifyIcon component. Pass messages on to the NotifyIcon object's wndproc handler. No Icon. A Information Icon. A Warning Icon. A Error Icon.

Called by a data consumer to obtain data from a source data object. The GetData method renders the data described in the specified FORMATETC structure and transfers it through the specified STGMEDIUM structure. The caller then assumes responsibility for releasing the STGMEDIUM structure.

Called by a data consumer to obtain data from a source data object. This method differs from the GetData method in that the caller must allocate and free the specified storage medium.

Determines whether the data object is capable of rendering the data described in the FORMATETC structure. Objects attempting a paste or drop operation can call this method before calling IDataObject::GetData to get an indication of whether the operation may be successful.

Provides a standard FORMATETC structure that is logically equivalent to one that is more complex. You use this method to determine whether two different FORMATETC structures would return the same data, removing the need for duplicate rendering.

Called by an object containing a data source to transfer data to the object that implements this method.

Creates an object for enumerating the FORMATETC structures for a data object. These structures are used in calls to IDataObject::GetData or IDataObject::SetData.

Called by an object supporting an advise sink to create a connection between a data object and the advise sink. This enables the advise sink to be notified of changes in the data of the object.

Destroys a notification connection that had been previously set up.

Creates an object that can be used to enumerate the current advisory connections.

Retrieves the next celt items in the enumeration sequence. If there are fewer than the requested number of elements left in the sequence, it retrieves the remaining elements. The number of elements actually retrieved is returned through pceltFetched (unless the caller passed in NULL for that parameter). Skips over the next specified number of elements in the enumeration sequence. Resets the enumeration sequence to the beginning. Creates another enumerator that contains the same enumeration state as the current one. Using this function, a client can record a particular point in the enumeration sequence and then return to that point at a later time. The new enumerator supports the same interface as the original one.

Retrieves the bits of the specified compatible bitmap and copies them into a buffer as a DIB using the specified format.

A handle to the device context. A handle to the bitmap. This must be a compatible bitmap (DDB). The first scan line to retrieve. The number of scan lines to retrieve. A pointer to a buffer to receive the bitmap data. If this parameter is , the function passes the dimensions and format of the bitmap to the structure pointed to by the parameter. A pointer to a structure that specifies the desired format for the DIB data. The format of the bmiColors member of the structure. It must be one of the following values. If the lpvBits parameter is non-NULL and the function succeeds, the return value is the number of scan lines copied from the bitmap. If the lpvBits parameter is NULL and GetDIBits successfully fills the structure, the return value is nonzero. If the function fails, the return value is zero. This function can return the following value: ERROR_INVALID_PARAMETER (87 (0×57))

A handle to a bitmap

A memory object containing a BITMAPINFO structure followed by the bitmap bits.

Unicode text format. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data.

A handle to type HDROP that identifies a list of files.

The length of the structure, in bytes. Before calling the GetWindowPlacement or SetWindowPlacement functions, set this member to sizeof(WINDOWPLACEMENT). GetWindowPlacement and SetWindowPlacement fail if this member is not set correctly.

Specifies flags that control the position of the minimized window and the method by which the window is restored.

The current show state of the window.

The coordinates of the window's upper-left corner when the window is minimized.

The coordinates of the window's upper-left corner when the window is maximized.

Gets the default (empty) value.

The corresponding touch point was established through a new contact. Cannot be combined with TOUCHEVENTF_MOVE or TOUCHEVENTF_UP.

A touch point was removed.

A touch point is in range. This flag is used to enable touch hover support on compatible hardware. Applications that do not want support for hover can ignore this flag.

Indicates that this TOUCHINPUT structure corresponds to a primary contact point. See the following text for more information on primary touch points.

When received using GetTouchInputInfo, this input was not coalesced.

The touch event came from the user's palm.
