Parameter

Description

hWndParent

Handle of the parent window.

nID

The controls ID.

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.

nCy

The height of the bitmap window.

Returns

!= NULL

The function was successful and the returned value is the window handle for the created control.

NULL

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.
