The EM_SETTARGETDEVICE message sets the target device and line width used for "what you see is what you get" (WYSIWYG) formatting in a rich edit control.

Syntax

To send this message, call the SendMessage function as follows.

lResult = SendMessage(    // returns LRESULT in lResult
   hWndControl,           // (HWND) handle to destination control
   EM_SETTARGETDEVICE,    // (UINT) message ID
   wParam,                // = () wParam; 
   lParam                 // = () lParam;
);

Parameters

wParam

handle to a device context (HDC) for the target device.

lParam

Line width to use for formatting.

Return Value

The return value is zero if the operation fails, or nonzero if it succeeds.

Remarks

The HDC for the default printer can be obtained as follows.

PRINTDLG pd = { sizeof(pd) };
pd.Flags = PD_RETURNDC | PD_RETURNDEFAULT;
if (PrintDlg(&pd))
{
    HDC hdc = pd.hDC;
    ...
}

If lParam is zero, no line breaks are created.
