Re: [Dev-C++] edit controls

[Carlos d. M. <cg...@wo...>]

I am learning windows, with a book after having read some tutorials, so I=
 cannot
say much, but I don't remember any answer, so here are my two cents:

In the Win32API reference (13MB) you can download at
http://www.cs.virginia.edu/~lcc-win32/, there are some pages about rich e=
dits,
the introductory one (which does not explain anything) says this:

A rich edit control is a window in which the user can enter and edit text=
. The
text can be assigned character and paragraph formatting, and can include
embedded OLE objects. Rich edit controls provide a programming interface =
for
formatting text. However, an application must implement any user interfac=
e
components necessary to make formatting operations available to the user.

I eyed the pages about rich edit controls very quickly, if I understood w=
ell,
you can use rich edit controls without OLE, although they support OLE.
In your message it seems like you don't know the DrawText function, which=
 makes
some wrapping of the text to the window (see below), and its prototype is=
,
pasted from the win32api reference:
int DrawText(

    HDC hDC, // handle to device context
    LPCTSTR lpString, // pointer to string to draw
    int nCount, // string length, in characters
    LPRECT lpRect, // pointer to structure with formatting dimensions
    UINT uFormat  // text-drawing flags
   );

lpRect is, of course, the rectangle defining the region of the window whe=
re you
want display the text.
This would be the better alternative to rich edits than textout, if they'=
re not
available without OLE, since it makes a part of the work.
