HWND LAnnotationWindow::CreateWnd(hWndParent, nID=0, dwStyle=WS_VISIBLE|L_BS_CENTER|L_BS_PROCESSKEYBOARD, x=0, y=0, nCX=200, nCY=200)

HWND hWndParent;	/* handle to the parent window */
L_INT nID;	/* the control's id */
DWORD dwStyle;	/* the control's style */
L_INT x;	/* x position for the annotation bitmap window */
L_INT y;	/* y position for the annotation bitmap window */
L_INT nCX;	/* width of the annotation bitmap window */
L_INT nCY;	/* height of the annotation bitmap window */

Creates the annotation bitmap window control using the specified parameters.

Parameter	Description
hWndParent	Handle to the parent window.
nID	The control's id.
dwStyle	The control's style. Apply any combination of window styles and LEAD window styles. For more information on Windows styles, refer to your compilers help file. For more information on LEAD window styles, refer to Bitmap Window LEAD specific styles.
x	X coordinate of the origin of the annotation bitmap window.
y	Y coordinate of the origin of the annotation bitmap window.
nCX	The width of the annotation bitmap window.
nCY	The height of the annotation bitmap window.

Returns

The window handle of the created window if the function was successful, otherwise NULL.

Comments

This function causes the class object to create the control window using the specified parameters.

It will also initialize the annotation automation engine..

This will fill in the m_hWnd data member with the handle to the new window.

If you call this function for a class object that already has a created window, the function will simply return m_hWnd.

L_INT LAnnotationWindow_CreateWndExample(HWND hParentWnd)
{
    // this will call the constructor and will initialize the bitmap window with the specified parameters.
