I started to write in MFC. I have to select some files then kick off a
process running the C program. I have the initial dialog file
selection stuff written, but am not sure how to run the C program
inside a seperate thread. I'm using VS.NET 2003 and am trying to use
the Thread and Process objects, but am not sure if I can use that with
MFC. I can't compile the code I have because I get some compiler
errors...
TAD2H5TDTestGui.cpp(57): error C3828: 'System::Diagnostics::Process':
placement arguments not allowed while creating instances of managed
classes.
TAD2H5TDTestGui.cpp(148): error C3828:
'System::Threading::ThreadStart': placement arguments not allowed while
creating instances of managed classes.
TAD2H5TDTestGui.cpp(149): error C3828: 'System::Threading::Thread':
placement arguments not allowed while creating instances of managed
classes.
I looked up what placement arguments are in the documentation, but
found that I don't have any in the code. Here's the code with the line
numbers marked that have the errors. I've include both the header and
the source file, where the errors are.

I'm not sure what I'm doing wrong. Also, if you have any other
comments like what are you doing that for, please let me know. I
usually try things until they work, but that doesn't mean that it's the
best way to do it. Thanks for any and all help...
