I have my website located on a remote server, and there is a MDB database on the server. The Server is Win 2000 Advanced Server. I want to make such a software in VC++ that can import data from the remote database and show the filtered records to the client.
Can this thing be made in VC++, if yes then please help me how to make this thing.
Regards

Are you familier with Client/Server programming? Do you know how programming with sockets?

Ya I am familier with Socket Programming.
But the socket can only send and receive message among themselves. How will the socket get the database records to send to the client socket. How will the server socket connect itself to the database.

Server does not connect to database. Your client must drive and work with your database. Client gets commands from server and returns data (results).
Then server shows data (Database records) in such a list control.

OK, Thanks for your reply. Then please tell me how to connect the client socket to the server datbase. Usually we use ODBC or ADO to connect to the database on the PC we give the DSN or direct address of file and connect to it, but how will we connect to the database that is located on the web server. Indeed I can make a DSN pointing to my database on the web server

I am trying to create a Windows Service tonight that can be called via ASP and ASP.NET, as a way to store session state between them. Getting the service going in .NET with C++ is proving a nightmare, I create a skeleton and it won't compile, there is no meaningful help, etc.
Can anyone help me ?

Do you want a service in managed c++?
If you just need a service, I have a small skeleton I have used for several services, and I have also compiled it as managed C++...
Do you want a copy?

I'd love a copy, so long as it's callable from classic ASP via COM. I don't need managed C++, the standard C++ one would be better.
Thanks heaps.

Woops, I did not think about that, it's not callable via COM 
Why don't you make a new ATL Project, then you can select "service" from the wizard.
That's the easiest way to get a service that you can call via COM 
Right now my service skeleton only works with Named Pipes as communication to the "outside world", but if you are interested, just ley me know, and I'll send you a copy tomorrow...

Yeah, but the resultant service does not compile and it seems most of the help on creating C++ services has been removed to make room for the exciting news that I can do it in VB.NET.
Thanks all the same.

Hi everyone.
I am working on a small program for school project. Apparently the teacher does not want to help so I decided to look for a help on the message board.
I need to write a function that takes seven digits input by user
ex. 123454 store them in the array and after that do some mathematical operations on them such as add, multiply.
Well, I can read them in as characters and tried to converted them into int after inputing to array but did not work.
I tried casting with the same result.
Can anyone suggest what should I do in order to read in as characters and convert them into integers. ( the whole program should resemble calculator that will add two big numbers let say 16 digits.)
Any help would be appreciated.
Here is my code.
#include <iostream>
#include <cstdlib>
#include <string>
using namespace std;
void main() {
const int ROWS = 6;
char inNum1 [ROWS];
int sum = 0;
int conValue = 0;
cout << " enter your number" ;
for ( int i=0; i <rows; i++="" )="" {
="" cin="">> inNum1[i];
}
cout << "num [0]= " << inNum1[0] << endl;
cout << "num [1]= " << inNum1[1] << endl;
cout << "num [2]= " << inNum1[2] << endl;
for ( int j = 0; j< ROWS; j++ ) {
sum += inNum1[j];
}
cout << "total sum = " << sum << endl;
}

Read the user's input into a std::string, which will properly null-terminate the char array so that atoi() works.
std::string sInput;
cin >> sInput;

Thank you, I will try this tonight, the pointer looks good.

The old fashioned trick was to subract ASCII 0 (zero) from the character, e.g.
for ( int j = 0; j< ROWS; j++ ) {<br />
sum += inNum1[j] - '0';<br />
}
You of course need to validate the data, i.e. is it between 0 - 9

Why not just:
int foo;
cin >> foo;
On the other hand, the following effectively rules out plain integers:

Perhaps you could use __int64? If not, you better look up a large integer library such as GNU MP or NTL.

Thank you for advice, I will try this tonight once I come back to my project

I want to do somehting as soon as all child windows(controls) in a CDialog based window have been created and painted, but obviously I can't do it in the "OnInitDialog" function because "OnInitDialog" is called BEFORE anything is painted. Is there a good way to handle this? Thanks.

What's your reason for doing this?
A. Riazi

Use PostMessage() to post a user defined (WM_USER + x) message to your dialog from OnInitDialog(). The message handler function that you create to handle this message will be called as soon as OnInitDialog() has finished it's processing.

hi all,
does anyone know how i can check whether a pointer to a class, say MyClass *pMyPtr actually points to a myClass object?
thanx,
Paul
 ;)

this might help:
if (dynamic_cast < MyClass * > ptr)
{
}

Hi all,
Whats the best way of pinning down memory leaks / corruptions?
I've got one I just can't find - the debugger catches it but after the event and gives me no useful information about the true cause.
So how do you find errors like this:
HEAP[myapp.exe]: HEAP: Free Heap block 1929b0 modified at 192de8 after it was freed

grab the free trial of Purify or BoundsChecker.
or, find all the places in your code where you modify the contents of something you allocated with new or malloc, and make sure you don't run off the end of that array/object.
-c
A | B - it's not a choice.
|
|

Thanks I grabbed a trial of Purify - it didn't really help with this one as it only spotted the problem after the event and couldn't really pinpoint the source much better than I knew already. It did how ever find a few other problems which I hadn't noticed though!
Anyhow I eventually found it by hand after determining the complicated trigger sequence!
Thanks for your help.
