i had created a client server program in MFC using TCP but by doing this the server can only work on one computer because you have to tell the client the ip address to connect to i.e
so i want to change my code so that i can use broadcasting but i found out that it only works using UDP. I tried changing the code but the error message "error with sendto: 10047" displays when i run the program.
that error means
Address family not supported by protocol family. An address incompatible with the requested protocol was used. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in sendto.
here is the code from server:
Code: WSADATA wsaData; WSAStartup(MAKEWORD(2,2), &wsaData); int port = 7171; if (param) port = reinterpret_cast<short>(param);
Are there any good free or commercial software that can check the C++ code style and find any codelines that violate a given code style specification? For example, whether the codeline is indented proplery, whether the variable is using Hungarian naming notation?
I have this function and it works, the problem is that it couts a bunch of stuff that I don't need. What this functions does asks the user to input a job (show) and if the show is found to list all the talents (actors/actresses). If the show is not found, to print "show not found". I have the function working just need to present it better. What I want the function to do is just print "show not found" and nothing else. How I have it currently will print:
Notice how its outputting all the unnecessary information. If the job is found should look like this:

Code: void TalentsByJob(Agency Talents[], int limit) { system("CLS"); string show; cout << "Enter the Job: "; cin >> show; bool found = false;
1. Read FILE.INP as input file and run its code execution. 2. When finish, RUN.EXE will produce FILE.OUT as the output of its code execution. 3. However, if calculation made in the code execution come to unsatisfied condition, RUN.EXE will terminate without producing FILE.OUT or partially produce FILE.OUT.
I want to write a program using MFC which I can set a several input case. The program should be able to:
1. Call RUN.EXE. 2. Wait for RUN.EXE to exit. 3. Continue with other code.
I can't modified RUN.EXE. I can't have RUN.EXE callback my program to let know it finish its work.
Are there any functions to call RUN.EXE, a MS-DOS program? Are there any way for the program to check if RUN.EXE finish its work and exited?
I am working on VS2008. I have two separate projects which have almost same functionality along with same file names but few are different. So I decided to use the same .cpp and .h files for both the projects. Both are Dialog based applications.
So what I did is I merged the source code changes to one by using #ifdef XXXX in all the common .cpp and header(.h) files.
I also moved the .rc file and .vcproj file to other project (As they were of different name).
The problem is with the resource.h file, as it is the file with the same name in both the project. By using #ifdef XXXX in .cpp files the compilation is working file but here in resource.h the resource is getting corrupted and the diglogs are not getting displayed.
As a starter project I want convert a Neural net app from "AI Techniques for Game Programming (2002 Buckland)" to a Visual C++ CLI Forms application. I have created the interface and now I have to rewrite the in/output routines, amongst other things.
First question I have has to do with variable initialization used by Buckland. Code looks like this:
Excerpt from header file (CNeuralNet.h):
//------------------------------------------------------------------- //define neuron struct //------------------------------------------------------------------- struct SNeuron { //the number of inputs into the neuron int m_NumInputs; //the weights for each input vector<double>m_vecWeight;
[code]....
Question I have: what is the the function of ": m_NumInputs(NumInputs+1)" after the method declaration? Buckland does this in many places in his code. In this case it's a struct, but he does it with classes too.
Basically, I'm moving a VC project from my Windows 7 build machine to a new build machine that's running Windows 8.1. One of the pre-build steps (for a particular project) runs a script which needs to call the M4 macro processor (which is installed on my C: drive). I've been pretty careful to set everything up the same on both machines (including my PATH) but when I try to build the project on my Windows 8 box, MSVC's IDE shows me this error output when running the script:-
I am stress testing my webservers and I need to code or port a C++ HTTP GET flood onto this C++ bot sourcecode. I believe I will need GetTickCount so I can specify the duration of the flood as well. I already have the C++ HTTP Flood .cpp and .h files but have no clue how to put it together onto this source. This will be easier to do over Teamviewer as I'm already using C++ 6.0 and have been with no issues.
I am creating an application which will work as a static code analyzer after compiling my code in VS 2008 for VC++ projects. It will be a kind of code review.
how and where do I need to put my custom rule sets, and what should I do to create such a application.
I have a C++ code that reads the database password from the registry and decrypts it using CryptUnprotectData. We have to deploy this application on a Windows 7 machine.
When I compile my code on Windows XP and run it on the test Windows 7 machine, it works absolutely fine. When I compile the same code on my laptop having Windows 7 and run it on the test Windows 7 machine, CryptUnprotectData fails with GetLastError() return '87'. If I run this application on my own laptop with Windows 7 on it, it again works fine probably because my laptop has a lot of things installed including Visual Studio and all the service packs etc.
I believe I have missed out installing some dependency on the test Windows 7 machine but I am unable to figure out what is that. What is it that's making the Windows XP compiled code running fine on the test machine and not the code that's compiled on Windows 7.
Here is the call to CryptUnprotectData in the code:
I need to be able to disable the items on a CCheckListBox but I can't change the code that calls AddString. I know I can use the CCheckListBox::Enable function to disable an item if I have an index but I don't have the index which would be provided by AddString.
I've tried intercepting the LB_ADDSTRING message and then looping through the items in the control but the string has not been added at this point so the last item in the list is never disabled.
I used Spy++ to see what messages were being sent and I noticed that LB_GETTEXT was sent so I tried intercepting this message (ugly hack) but this caused my app to hang - I assume because of the number of times the message is sent. Is there a way to disable the items?
I'm expected to write a c program for this question :
Using these header files #include <stdio.h> #include <conio.h>
Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.
This is my problem in my subject programming but i dont how to use Array in windows form ... If i run my code i want my Data in listview would not be disappear if i close the form ...?
I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
I am making a game and want to make an updater that grabs the source code from a page on the web. Can this use things that are available to all platforms? It could just be something that grabs the text from the page and executing it (maybe using something like Python's exec() command ?) BTW I'm using mac
