"Pull over, pull over - semantics police!"

Critical sections, and all Win32 synchronization primitives, solve 1 and 2.

Some things that come to mind:
Have a common base object with a virtual destructor that does nothing - then remove all other destructors. This should route all destrutor calls to the virtual base...

It seems to me that 2 "strands" would be defined as 2 independent tasks that have no shared resources between them (or if they do, synchronization is involved).
If so, then replacing threads with...

I would detect the line ending style when opening an exist files and preserve it. When saving a new file, you could have an option settings for the default ending style to use or just ask the user...

I've implemented a couple of dynamic hash tables for different applications in the past. They needed O(x) guarantees and so they were implemented by hand and there was no rehashing. In other words,...

Have the user provide a handle for where the DLL should send its output. Then the user can provide a console handle, file, pipe, etc..

Definitely yes. More reading: http://preshing.com/20130930/double-checked-locking-is-fixed-in-cpp11/#using-a-c11-static-initializer
The rest of that post is good reading too.

With a compliant C++ implementation, this really all you need:
static simpleSingleton* getInstance()
static simpleSingleton s_instance;
If your compiler...

Correct again. I've been relying on RAII objects just "doing the right thing" for too long :)

That should be handled by the appropriate VS runtime redistributable. (eg. http://www.microsoft.com/en-us/download/details.aspx?id=30679)

Well, you wouldn't want to link statically to GPL source (without purchasing a license to do so). And some may even require a license to be used in a commercial...

What protocols are used when accessing your server? Is it plain HTTP? Through TCPIP or TLS (SSL)?
What libraries did you use to achieve this access on MacOS?

You are correct. My mistake.

A call to VariantInit() is missing (though the variant's initial values are not used in this case).
The VariantClear() call could be moved up 2 if blocks.
The call to...

One of your problems is the you are using an uninitialized variant and safearray. You'll want to use ATL's wrappers for these objects - CComVariant etc.

Are you saying that we should just be calling ::SetTimer in order to accomplish the task? Or that we should re-do everything in MFC in order to use its...

>> Make Simple Tasks Simple!
I couldn't agree more.
The "task" in this case - and the reason for my participation in this thread - is to have ::SetTimer() callbacks into a C++ object instance...

I'll choose a solid C++ interface over a C interface any day. I won't let a few lines of code stop me from creating one either.
If you have object instances that need their methods called on a...
