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

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.
