#include "ltwrappr.h"

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

Creates the annotation bitmap window control using the specified parameters.

Parameters

HWND hWndParent

Handle to the parent window.

L_INT nID

The control's id.

DWORD 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.

L_INT x

X coordinate of the origin of the annotation bitmap window.

L_INT y

Y coordinate of the origin of the annotation bitmap window.

L_INT nCX

The width of the annotation bitmap window.

L_INT 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.
