What exactly is your question? Are you unsure about what line spacing is? Or how to implement it?

here's some copy/paste's from a few recent threads on the vcpp list.  maybe you can get something out of them:

There's a sample somewhere in VC (I don't remember the name) that allows you
to do distortions to TrueType fonts.  It does it by using the BeginPath
function (and companions).  What it does is draw the text into a hidden
path, and then enumerate the points in that path, applying some calculations
to them.  This is probably all you need.  Otherwise, there are a set of
functions to get the geometry of individual TrueType glyphs (start by
looking at GetGlyphMetrics).

Bummer. I was hoping for a hilarious round of the usual flames
from Mr. Defensive.
Here's what I found out after testing the many good suggestions.

None of the handlers/overrides for ON_WM_MEASUREITEM_REFLECT,
ON_WM_CREATE, ON_WM_MEASUREITEM or PreCreateWindow is called.
Thanks to Trevor Russ for suggesting the method most compatible
with my goal of a reusable control:

void CMyOwnerDrawFixedListBox::PreSubclassWindow() {
        CClientDC dc(this);
        CFont* pOldFont = dc.SelectObject(GetFont());
        TEXTMETRIC tm;
        SetItemHeight(0, tm.tmHeight);


that last one was from mfc-l

i also think there's a settextmetrics function.. probably useful.

Pls try win32 function SOPutParaSpacing.
(A twip is 1/1440 inch, or 1/20 of a printer’s point).

Pls take a look at the answer before you reject it. The function can set the Baseline to baseline height, in twips.

To use SOPutParaSpacing,which file I have to include??
I include windows.h,but compilation error,undeclared identifier
occurs..Any sample code would be welcome

The head file is SODEFS.H that should be included. But it does not end there. You need to know features of the shell for the Windows operating system. I would like to provide you the following site for instruction:
There is also an example in the online help:
Visual C++ -> Visual C++ Samples -> SDK Samples -> Windows NT Samples -> Fparser: File Parser
And you should notice that there is no MFC function to do it. Maybe in the later version MS will provide it.
Good luck.
