Is there an easy way to talk to a USB port via VS C++.NET (2203, soon 2005)?
VS C++.NET has other easy interfaces (e.g. XML), so I was wondering if a USB
'inteface' is built into the language somehow? If not, is there a tutorial
and/or book and/or third-party widget I can get to ...

I was told that it is possible to set  the /clr compiler switch on a per
file basis. I find this option in the project settings for the .cpp
files. However that does not affect the header files. So if I have a
class that has managed members setting the /clr on a per file basis ...

I have several modules comprising of shared libs (i.e. dlls) and
executables. I would like to be able to do the ff:
1). Build each of the modules individually from the command line
(without having to start MSDEV) - ideally by having a make file in each

is there any performance difference between malloc() & HeapMalloc()?

When I try to compile a MFC extension dll with /CLR in VS 2005 Beta 2. I

Hey guys,
If I have a pointer to a *char, how do I allocate and free memory for it?
for example, if I had:
char*  pstring = "Hello\0";

I have defined a templated function:
template< typename dataT >
dataT Add_T( dataT x, dataT y ) { return (x+y) ; }
Now, I'd like to do something like:

I have in my PC the 'F:\' drive, it is an alias to '\\SERVER1\\DOCS'
How can I get the real path for 'F:\'?
How can I determine if 'F:\', 'G:\', etc. is a local drive drive or an alias
to SERVER path?

I am migrating modules from VC++6 to VC++7. All the dll and exe modules are
compiled successfully, but the applications crashes at startup.
Please guide me what are the proper steps to migrate VC++6 code to VC++7.

Hello, I created a MFC extension dll (using VS 2005 Beta 2) that is
supposed to export a class that uses .NET internally (See header below)
und later shall be used by a plain MFC Project (without the /CLR).
As soon as I try to specify __declspec(dllexport) (AFX_EXT_CLASS) I get

For some reson my code is generating a LNK1215 error, which 'suggests' I
re-install VS C++. So I did. which did NOT solve the problem. The weid part
is it seems to be caused by my one CPP file, but not sure how. It compiled
just fine. Then I made a simple change and re-compiled, ...

I am trying to create a dll that internally uses managed types but
exposes a plain unmanaged interface. All the managed stuff shall be
"wrapped out of sight". So that I would be able to use that dll from
pure unmanaged code (for example inherit from classes in that dll). Is

i have a compiled dll, and i want to see what values ar in certain methods

a text file on my desktop or qa desktop?
