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 don't think that's what the lounge is for.

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.

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?

p.s. The context is .NET remoting using MC++ and the BCL

I've got some problem trying to marshal an interface between threads in a process. 
In Win32 app I can call CoMarshalInterThreadInterfaceInStream to marshal and
CoGetInterfaceAndReleaseStream to unmarshal or use Global Interface Table
but I don't know how to declare this functions/Com class in the
.NET. Or mayby there is another solution build-in the framework.
Can you guys write some example how to use this functions/COM class
I'll appreciate it.
Thanks in advance

In my opionion the framework takes care of that for you.

That's right.
I found the answer in the .Net SDK.
But there is one requirement - both threads must be in the STA apartment, otherwise the function call on the interface will fail.

Hi! I am using an application that is using both managed to unmanaged code.
I want to copy data from a CString to a Stream* (it may be MemoryStream or BufferedStream - whichever is faster).
Can anyone help? Thanks
Best regards,
Alexandru Savescu

Sorry Nish, it does not work. Here is what I did:
CString str = "aaaa":
String* str1 = new String (str);
MemoryStream* mem1 = new MemoryStream (str1, false);
and the result is:
c:\Work\Test.cpp(332): error C2664: 'System::IO::MemoryStream::MemoryStream(unsigned char __gc[],bool)' : cannot convert parameter 1 from 'System::String __gc *' to 'unsigned char __gc[]'
I found an work arround that compiles and works but I hate it:
MemoryStream* mem = new MemoryStream (n) ;
for (int i = 0; i < n; i++)
mem->WriteByte (str[i]);
Do you have another solution?
Thanks!
Best regards,
Alexandru Savescu

Try this:
CString str = "aaaa";
String* strText = new String (str);
Byte message[] = System::Text::Encoding::ASCII->GetBytes( strText );
MemoryStream* sStream = new MemoryStream( message );
If you want to use diffrent encoding replace the bold text with the appropriate encoding like: Unicode, UTF7 or UTF8.
I should work
