I am using Excel to call the win api openfile dialog with the
OFN_ALLOWMULTISELECT flag set (I am selecting multiple files).

Everything works fine until I select too many files, then my function
returns nothing:-(

I have tried increasing the size of the string buffer:
udtStruct.lpstrFile = String(400#, 32)
which runs, but doesn't increase the number of files I can select. Nothing
above about 254 seems to make a difference.

Is this a limitation I am going to have to live with?

Thanks in advance,
Mike Weaver
