virtual HWND LAnnToolBar::Create(hWndParent, pPoint, uAlign, bVisible, uButtons=NULL, pButtons=NULL)

HWND hWndParent;	/* handle to the parent window */
LPPOINT pPoint;	/* pointer to the POINT structure */
L_UINT uAlign;	/* constant for the toolbar allignment */
L_BOOL bVisible;	/* flag that indicates whether the toolbar will be visible */
L_UINT uButtons;	/* number of buttons the toolbar will have */
pANNBUTTON pButtons;	/* array of ANNBUTTON structures that contain toolbar button information */

Creates an annotation toolbar in the specified window.

Parameter	Description
hWndParent	Handle to the parent window.
pPoint	Pointer to the POINT structure that specifies the position of the new window in the parent window. Coordinates are relative to the parent window.
uAlign	Value indicating which corner of the toolbar is located at pPoint. One of the following values:
	ANNTOOLALIGN_LEFT [0x0000]
	ANNTOOLALIGN_RIGHT [0x0001]
	must be combined using the bitwise OR with one of these values:
	ANNTOOLALIGN_TOP [0x0000]
	ANNTOOLALIGN_BOTTOM [0x0002]
	For example, ANNTOOLALIGN_LEFT\|ANNTOOLALIGN_TOP indicates that pPoint is the top left point of the toolbar.
bVisible	Flag that indicates whether the toolbar will be visible. Possible values are:
	Value	Meaning
	TRUE	Toolbar will be visible.
	FALSE	Toolbar will not be visible.
uButtons	Number of buttons that will be in the annotation toolbar. This value is valid only if pButtons is not NULL.
pButtons	Array of ANNBUTTON structures that contain information about the tool buttons to include in the annotation toolbar. If this is NULL, the default annotation toolbar will be created.

Returns

>0	Handle of the created toolbar.
=NULL	An error occurred. Refer to Return Codes.
