What are you doing??? You been MC++ing for a while now! Are you developing some kinda killer app with MC++ ???
LOL, all will be revealed when I submit my article for the competition (I will be shaving the closing deadline rather close  )
Obviously it is not a killer app, too much overhead for me in learning MC++ to produce a killer app on my first go. But it is pretty cool nonetheless, uses a host of new capabilities in the language and framework.
A clue: It uses the Code Project webservice, but is not a screen saver or a ticker effort.
I actually only got serious on the article this monday, been fooling around figuring things out up until that point. Now my ass is in gear

Most definitley Nish. You are a great editor and article writer. You should check the messages on your articles, I posted one (the MC++ intro that that one idiot wrote that nasty post on.)

How are you using gcroot?

Hello Rama/James
It's a well know bug it seems. It happens when you use gcroot in an MFC application compiled with /clr.
See this reply from a Microsoft guy in reply to a similar question that got asked in the dotnet mailing list.
From: "Mark Hall (VC++)" <markhall@MICROSOFT.COM>
Subject: Re: gcroot template with warning C4244?
This is a mismatch between the way the GCHandle class is defined and the
way C++ implements the -Wp64 warnings. In short, intptr_t and
System::IntPtr were not recognized as fully compatible. This will be
fixed in the next release.

What is weird in it? It is very valid warning. It says that for 64 bit code your casting would create problems. What is the line of code?

Does anyone know what is the function in Palm SDK that gives me the time in milliseconds?
Thank you.

Well where can I post this question and get a useful answer.

I had a table called user and it had a field called password. My SQL worked when directly executed into Access XP, but failed via OleDbCommand. Finally I had to rename the table User to Usr and the field password to passwd!
Does User and password have any special meaning to OleDbCommand or is this another MC++ issue????
I don't remember similar issues with C#

If I have a long string :-
"aaa.........lonnnggg............bbb"
and I want to write it as
"aaa........"
"...longggg..."
"...bbb"
I get a compile error of "newline in constant"
I remember being able to do this in VC++ 6!
What do I add as a line break character to do this in VC++ 7 for an MC++ project?

Let's say we have a class A that wraps a DB table. Now suppose this has an Add method, should we use a OleDbConnection local to that function to do the insert? Or should we have a OleDbConnection member for the class A and open it in the constructor and kill it in the destructor. The Add function is an infrequently used function. A is a remotable object and my worry is that it might be kept alive too long and in such cases if there is a network outage or something, I am scared that the class will be destroyed out of the blue and the DB might not be closed properly.
Any suggestions are welcome

You may be better off using a DataSet. It caches data from the server and you can store it on the client (Assume you connect to a data source and display everything in a data grid for example)
Then you will perform any operations on the client and update everything in the end. Thus, you do not have to worry about the connection being help up.
For additional info on datasets check my article here.
I hope that helps.

Problem is that the DB connection is on the remoting server and it's the client that invokes calls remotely. The kind of app I have in mind had an issue that a client might connect and then disconnect only after 6 hours or even a full day. I am worried about a connection being alive for that long and timing out in between. Datasets also don't seem same for this. If a network failure occurs, then I won't be able to flush the data in time.

Well, having a connection open for 6 hours non-stop is bad in every sense you want: bad design, bad implementation etc. The Internet itself was not designed to keep connections alive (see the IP protocol). You have every reason for connections alive that long. You don't speak on a phone that much (and a phone keeps a connection open)
Anyway, datasets may be a better option. You may from time to time flush data in backgound (say every 30 minutes). Also, if data is not flushed on time (or timeout occurs when updating) then you can catch an exception and always retry.
Best regards,

It's not about bad design here Alex. I don't have a choice here. A remote client may do what it wants to. We cannot dictate to it to close after a minimum while
I like your periodic flush idea. I'll do that.
And yeah, I'll take a look at your Dataset article too 
Thanks

If I need to remote 3-4 objects, should I start as many TcpChannels as there are objects and listen on them, meaning I have 4 ports open; or is it better design to have one master object which is remoted and which has methods to return each of the n number of objects?
Regards
Nish
p.s. The context is .NET remoting using MC++ and the BCL
