Hello,

I hope there is a solution to this.

I am required to develop a service application using Visual Studio
.NET.

I am required to develop it using C++.

Originally we set out using Visual Studio .NET 2003. But for the
database bugs in this framework, this environment supports Windows
Service project type for the C++ language.

I currently have a solution prepared and (mostly) working but for the
.NET framework database bugs.

The application requires Visual Studio .NET and the Service Pack 2 in
support of key database connection patches.

Unfortunately there is no Service Pack for VS.NET 2003 or the decision
would be easy to remain using 2003.

There does not appear to be a Windows Service project available in the
C++ language?!

Is it easy to add such a project type? Or do I simply start from a
blank project and copy over any source code that supported the VS.NET
2003 solution?

If necessary I'll use the C# language since this seems to be
outweighed by framework robustness where database connectivity is
concerned. And the C# is close enough to C++ to make the migration not
as painful.

Any similar experiences would be appreciated.

Best regards,
Michael Powell

It took a few readings to figure out which products you're talking about in
each sentence, but I hope I've understood your question correctly...

VS.NET 2002....

... .NET framework 1.1 that VS.NET 2003 supports. What bugs might these be,
by the way? In general I've found 1.1's database support to be superior to
1.0's support.

.NET 1.1 framework, that is.

.NET Framework 1.0 Service Pack 2 and VS.NET 2002.

It's not easy to add a project type, but there's nothing magic about project
types - they're simply templates that get you started. Simply copying your
.NET 1.1/VS.NET 2003 solution files into a net .NET 1.0/VS.NET 2002 project
is certainly a good place to start. Since VS.NET 2002 didn't (apparently)
support a Windows Service project type for managed C++, there may be
something that prevents it from working - that I don't know.

You could, of course, build a traditional native Windows Service, using
OLE-DB or ADO or ODBC to access your database and get away from using the
.NET framework at all.

That's certainly another option.
