Visual C++ :: MFC Execute DOS Program And Resume Code At The End
Jun 9, 2013
I have a Third Party MS-DOS program, RUN.EXE
RUN.EXE do the following:
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'm working on a project that's got a lot of moving parts, from feedback from a position sensor to real-time video editing. The script that runs the sensor is in C++, and the API for the video editing software (vMIX) is executed with HTTP protocol. I'm hoping to use that C++ script to control the video software (as some of the editing is dependent on particular feedback from the sensor), and wanted to see how to execute a HTTP command from a C++ script.

I'm trying to create a program that will show what the 12th digit of a UPC code would be. However, once the user enters the first 11 digits the program doesn't execute the last call of printf. The program compiles with no issues.
Code:
#include<stdio.h>
int main() {
int o1, e2, o3, e4, o5, e6, o7, e8, o9, e10, o11, oddsum, evensum, twelve;
printf

I'm new to C++ and am trying to create a program to solve the problem as described in this image: [URL] .....
Here's my code. It fails to execute the main part of the problem (years, population of A & B) but works well in recognizing errors (if PopA >PopB or if growth rate of PopA<PopB)
Code:
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
int main() {
string city1, city2;

System();is bad, I get that. Is there another way, that works across platforms I can use to execute an external program. If not, is there a windows specific way.

I wish to add the item 'Website' to an MFC Dialog app System Menu so that it can activate the following method:
Code:
void CMyDlg::OnWebpage()
{
ShellExecute( NULL, NULL, _T("[URL]..."), NULL, NULL, 0 );
}// OnWebpage()
I have tried this:
Code:
#define IDM_WEBSITE (WM_USER + 101)
//..
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
pSysMenu->AppendMenuW(MF_STRING, IDM_WEBSITE, _T("Website"));
}
[Code]...
The code compiles without error but and the 'website' item appears on the System Menu but it doesnt do anything.
I've inspected the following but don't really understand how it works and it seems to me there should be a simpler way to accomplish my end.

I'm programming an app that deals with large numbers. I have a do-while loop that I want to execute. I can not get it to work. The "while(d!=1)" part is the problem and I can not find a way around.
Code:
#include "stdafx.h"
#include <stdio.h>
#include <gmp.h>
#pragma comment(lib, "gmp.lib")
int main (int argc, char *argv[]) {
mpz_t d;
[Code] ....
I get errors:
1.error C2446: '!=' : no conversion from 'const int' to '__mpz_struct *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
2. '!=' : '__mpz_struct [1]' differs in levels of indirection from 'const int'

I am trying to create a program that would execute a foreground process. I have this code for the foreground process
Code:
#include <stdio.h>
#include <signal.h>
int main() {
int temp;
printf("We are in the current program
[Code] ....
And this is my main program
Code:
#include <unistd.h>
#include <signal.h>
#include <stdio.h>
int main() {
signal(SIGINT, SIG_IGN);
[Code] ....
My main program stops executing after the process "./scanf" executes and there fore does not print the line "How are You"...
I want to main program to continue executing after "./scanf" finishes. How to achieve that?

The problem is with the first "Type and Run," where the code looks like this:
Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>
void do_heading(char *filename);
int line = 0, page = 0;
[Code] ....
I am using the gcc compiler in Ubuntu 12.04 LTS and I get the following error:
Code:
print_it.c: In function "main":
print_it.c:36:15: error: "stdprn" undeclared (first use in this function)
print_it.c:36:15: note: each undeclared identifier is reported only once for each function it appears in
print_it.c: In function "do_heading":
print_it.c:49:16: error: "stdprn" undeclared (first use in this function)
I was told that "stdprn" can be recognised by a DOS based compiler and the book says I can try using "stdout" instead. It looks like this now:
Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>
void do_heading(char *filename);
int line = 0, page = 0;
[Code] .....
It compiled OK with the gcc compiler but I only get this when I run the program:
Code:
Proper Usage is:
print_it filename.ext
I am not sure whether I should continue looking into this but even when I tried compiling and running it on Windows, the .exe file won't even launch. The other ones do but this first one doesn't.
Questions:
1. What should be done to make this program run?
2. Even though the book says "don't care" if the reader does not understand the items (It's Day 1/Lesson 1), I would still like it to run as I don't want to experience compiling and running problems in the future. Should I even bother doing this section of the book or is it obsolete and should be skipped?

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
Code:
ServerAddr.sin_addr.s_addr = inet_addr("10.13.31.112");
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:
Uploaded with ImageShack.us
Code:
void TalentsByJob(Agency Talents[], int limit) {
system("CLS");
string show;
cout << "Enter the Job: ";
cin >> show;
bool found = false;

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.
how to merge two resource.h files to one.

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:-
m4 failed with exit code 255

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 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:
if (CryptUnprotectData(
&cipherText,
NULL,
NULL, // Optional entropy
NULL, // Reserved
NULL, // Optional PromptStruct
CRYPTPROTECT_UI_FORBIDDEN,
&plainText))

Debug build links fine but release build linking hangs at "code generation"
If I turn off whole optimization, it actually works fine, but I do need whole optimization.
