Multiple file select in CFileDialog

I have a strange bug with using a subclass of CFileDialog to allow the user of my app to
select files.

I have a subclass called CFilePreDialog and basically the "standard" CFileDialog file browser pops
up and the user selects a JPEG file and then clicks "Open".  Works great.  Now, using the standard
windows feature, the user may "hold down CTRL and hilite multiple files" and then click "Open" and
all these files are selected.  This works great if the number of files is 2 or 3 or 4, but at some point
(may depend on file size? but not sure) it doesn't work.  Generally, if you try to hilite and select 8
or 10 files, it won't work.  The panel vanishes, and it acts exactly as if the user had pressed the
"cancel" button on the panel.

So what's up with this?  Why would the number of files selected matter?

You need to be sure your buffer is large enough.

m_ofn.lpstrFile = stringbuffer
m_ofn.nMaxfile = length stringbuffer

tullhead - if you don't understand a comment then ask for further explanation.  The second comment by jimwasson apologised for making a duplicate of what I suggested was the problem.  That should have given you a strong hint that I deserved a thanks at least.

Thank you AndyAinscow - I should have thanked you before.  
But I suspected there was something too full, some buffer somewhere,
so your comment wasn't too helpful.  I gave the points to jimwasson
because he told me exactly where the problem was.
