IMHO there should be NO problem.

Actually, you can do Win32 API programming (even plain C) with Visual C++.

Why would you need to store a global variable in a different data segment?

I'll take a guess and say no.

are you handling the click event of the mouse?
May be there is some indefinete/infinite loop running in your code. I guess it would be very hard to detect the error without you posting some relevant code or describing the exact scenario.
Somethings seem HARD to do, until we know how to do them.

Can you more explain about your program and how do you call them how do you make these dialogs and what are these?
|
|

Oh sorry i forgot to mention - prob is in resource editor not when the program is running...
|
|
|
|
|
When you run your program it works? and did you use of breakpoint on your code?
|
|

its working fine when i run myu program . .. Ima telling about the designing. when im designing the dialog box or any resources. . . my VC6.0 hangs out...

Are the images huge? Does it happen with all of them, or just a select few? Instead of 50 images, what if your project only had a few?

There are no images but various controls more than 15 controls in each dialog box.
For all the dialog boxes when i try to add or remove a new control or just change the property of a control, the editor hangs...
The same code works fine in some other systems.
No problem when my project have very few dialogs..

hello ppl,
i m relatively new to vc++. I need to know how can i create report(s) using the data available in a table in oracle10g database.
To tell you a little about my MFC and VC++ knowledge:
so far i have created an application that receives a string on ethrrnet, parses the string, and puts the extracted data into relevant fields of the table in database.

Hi to all
Anybody give me the suggestion og reuse of Socket.
In my socket programme,server will receive the client
in server socket , to disconnect the client i used socket shutdown and close to disconnect the client.After another client can connect to the server but they cannot transfer the data between them.This is multi threading programme.
(As my knowledge shutdown and close option is completly end the socket therfore we must restart the socket.)
Give me the suggestion to solve this.

Not very clear about your problem from your post.
Generally, for a server process you will,
1. Initialize Winsock
2. Create a socket and bind it to network interface and port. NOTE: This is the listening socket
3. Then, you can say, prepare the socket to listen for connection request in that socket
4. Then you wait on that socket for incoming connection by accept(..) call.
When this call returns, it will return a new socket where the client is connected. Note that the original listen socket is not used by the connection. You take the new socket returned by accept(..) and do you communication and finally close it. You must not close the socket on which you are listening.
So in that regards, I am not sure in your post, which socket you are closing.
(Even if you are using Unix/Linux the concept remains the same as they are POSIX sockets)
Look at the example given in the link:
http://msdn2.microsoft.com/en-us/library/ms737526.aspx
Within the example, once accept has return with a valid connected socket (a.k.a the 'else' portion of the check)
you can initiate a thread where you will use the socket to do your stuff with the client and close the socket.
You only close the socket you are listening on, when you terminate the server app or you do not wish to listen for connection on that socket any more.

Wanted to add that, once accept(...) returns, and you deal with you client (either by initiating a separate thread or in the same thread) you need to go back to wait on accept(...) again to server other incoming request.
With the close & shutdown call, I remember an issue about the TCP/IP stack taking some time to actually making the socket available for further reuse and the workaround was (as far as I remember) to set socket option to socket reuse.

hey pals, i was trying to extract the decimal places out of a "long double" type variable and then store them in an "integer" type variable.
First I stored the long double value in a long integer type value then I subtracted the long integer value from the original long double value, thus, I got the decimal portion of the long double value and I stored tis decimal part into a separate variable.
Now, I under a while loop (which ran uptill the value in the variable holding the decimal part didn't became zero) I multiplied the decimal value holding variable by 10 and stored result in a temporary long double variable, I then copied this new value into an integer variable and subtracted the integer value from the new long double value that left me with one less digit after decimal as i was having initially. NOW until the value of the temporary long double variable doesn't becomes zero this loop runs but this loop is running more number of times as desired. After the value ends in the temporary long double variable, this variable takes up a value = 2.55351e-15 and keeps on running.
How to avoid this ? ? ??????????????????????????????????

I'm not exactly sure what you are after, but see if this is even remotely close:
double d = 123.456;
char s[16];
sprintf(s, "%.3f", d);
int n1 = atoi(s);
int n2 = atoi(strchr(s, '.') + 1);

or maybe you wanted this?
long double IntegerPart;
long double FractionPart = modf(OriginalLongDouble, &IntegerPart);
long lIntegerPart = (long)IntegerPart;
long lFractionPart = (long)FractionPart;

I newbee to OO so ...
Is deriving a Class and Writting your own constructer for the base a way of accessing the bases private members ??
|
|
|
|
|
Kind of - if a constructor sets the values, you can use it to set them. But, once they are set, you cannot access them, unless public methods are offered to do so ( often a class will offer methods to get, but not set some of the values )

Meaning you the drived Class can access the private members only once durning initilization I guess to put total control on a data members can
add const to private ?????
|
|
|
|

No, private members can't be accessed even at initialization. The constructor you are refering may be public or protected. If your constructor is private then that constructor cannot be accessed from outside the class.
