Parameters

HWND hWndParent

Handle of the parent window.

L_INT nID

The controls ID.

DWORD dwStyle

The style of the window control. 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 for the origin of the bitmap window.

L_INT y

Y coordinate for the origin of the bitmap window.

L_INT nCx

The width of the bitmap window.

L_INT nCy

The height of the bitmap window.

Returns

Value	Meaning
!= NULL	The function was successful and the returned value is the window handle for the created control.
NULL	An error occurred, and the window could not be created.

Comments

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

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.
