IE_GETPAINTDC
Retrieves the handle to the device context (
HDC), which is used to paint an ink edit control. This
HDC was supplied to the iedit control by
BeginPaint; therefore, its clipping region is set according to those portions of the
iedit control that have been invalidated.
Parameters
wParam
Not used; must be 0.
lParam
Not used; must be 0.
Return Value
Returns the
HDC if successful; otherwise, returns one of the following:
Constant
| Description
|
IER_PARAMERR
| wParam or lParam is invalid.
|
IER_NOTINPAINT
| Attempted IE_GETPAINTDC outside of paint notification.
|
Comments
The application can send this message only when the parent window is
processing one of the painting notifications: IN_PREPAINT, IN_PAINT, IN_POSTPAINT, or
IN_ERASEBKGND. An attempt to send it at any other time will fail, returning
IER_NOTINPAINT.
The clipping region is already appropriately set when sending IE_GETPAINTDC.
The
HDC is in the MM_TEXT mapping mode. The
HDC must not be released; the iedit control does this after returning from the
painting notification.
