Visual C++ :: Cleaning Code For Better Console Presentation?

Dec 17, 2013

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;

C :: Cleaning Up Logic On Linked List Deletion

Jan 14, 2015

I have a doubly linked list from which I need to occasionally delete elements (any elements that have a type value different from 0). The function I have seems to work, but looking at it, I think I could probably make the logic cleaner.

The structs in questions are declared here, with irrelevent variabled omitted:

Code:

struct Event {
//...
int type;
//...
struct Event *next;
struct Event *prev;

C/C++ :: Converting Integer Number To Its 2's Complement Presentation

Jan 28, 2014

I am working on an assignment about converting an integer number to its 2's complement presentation. The binary representation is consisting of a single linked list.

As we all know, the steps of this converting is to taking the reminder of the absolute value, then flipping the 1 to be 0, and the 0 to be 1 in the binary number. And the last step will be to add 1 to the binary number invers.

I wrote a code that implements every thin correctly. However, when I reached the part of adding 1, the program was hanged.

int Absolute; //the first step is to convert the number to the binry reprezentation
Absolute = abs (value);// by take the Absolute value of the negative number, then find the
while (Absolute !=0) //the binary reprezentation {
int res;
res= (Absolute % 2);
pushFront (res);
Absolute /=2 ;

Visual C++ :: Run MFC Application From Console?

I have a question about to run an MFC dialog based C++ application from console: if I run my application from console, I see the application start and the console immediately back to prompt. I need that console wait the application exit before show me the prompt again. I tried on Visual Studio 6, 2005 and 2010 but the behavior is the same.

Visual C++ :: Receiving Windows Message In Console Application?

Oct 11, 2013

I'm trying to write a program that passes Windows messages back and forth from another program that controls a laboratory instrument. I was able to write a program that successfully passes instructions, as evidenced by the instrument doing what I tell it. However, I am having trouble getting a return status from the instrument. The manual instructs the following:

// demo code, etc.
// send message to the instrument operating software here...
SendMessage(hwnd, WM_COPYDATA, tag, (LPARAM) &cd)

Either a completion message or return data is returned. Remote commands ReturnStatus, ReturnTiming, and ReturnData return data. In either case, data is received through an asynchronous windows message inside Win32 COPYDATASTRUCT type data packet.For example, a typical OnCopyData window callback is shown below, where the string data retrieved is finally stored into a Microsoft CString object. Note the use of variable replyTag, discussed above, which is used to isolate the correct windows message returned.

BOOL CUserDlg::OnCopyData(CWnd* pWnd, COPYDATASTRUCT* cd) {
….
if (cd->dwData == replyTag) {
/* String pointing to status */
CString retStatus = (char*) cd->lpData;
}
….
}

I can't tell if my problem is in generating the replyTag, getting the HWND to my own console window, or the actual receiving part of the code.

When setting the replyTag, the manual instructs: UINT replyTag = RegisterWindowMessage(“SOFTMaxProReplyMsg”);. However, I have to put an "L" in front of the string or I get a data type error (can't convert const char* to LPCWSTR).

When setting a HWND for myself, the manual instructs: HWND MyWnd = GetSafeHwnd().

That produces an error because GetSafeHwnd is a function of the Cwnd class, and I don't have a Cwnd. I have replaced it with HWND MyWnd = GetConsoleWindow();

When listening for the reply message, the manual instructs what I quoted above. However, I again don't have a Cwnd. I therefore simply used

if (cd.dwData == replyTag) {
CString retStatus = (char*) cd.lpData;
}

The above if statement always evaluates false, and the cd.lpdata contains the message that I had sent out instead of a reply message. How to get a reply using my console application. Here is the full code of my function:

Code:
#include "stdafx.h"
#include<iostream>
#include<vector>
#include<string>
#include<afxwin.h>
using namespace std;
void SendCommand(string command) {
// Get tags to identify the receiving and sending messages

Visual C++ :: Running / Debugging Console App That Needs Admin Privileges

Nov 4, 2012

I see there's something called a manifest file but VS C++ EXPRESS seems different than non-express. The solutions I've seen show applets/tabs that I don't have in Express.

In one of my physical DEBUG folders are some .manifest. files and some a .res and .rc file.

I know you need to edit the XML and change asInvoker to requiredAdministrator (or something like that).

The confusing part is if I go into Project Properties, MANIFEST TOOL caret/tree, under INPUT AND OUTPUT, it shows this .manifest file is OUTPUT. It's as if it rewrites it every time with some defaults? I have edited it, but I see it's back to asInvoker. There is a spot to put in a ADDITIONAL manifest file (or .res file).

Does a manifest somehow affect the physical .exe file (something is imbedded in it??)?

How do I change my project to make sure that the .exe always runs as Admin? Will doing this ALSO allow me to DEBUG it in VS C++ EXPRESS without having to do anything different (play with manifest or run VS outright with Admin level)?

C :: Possible To Split Command Console Into 2 Parts - Visual And Text Area

Feb 1, 2015

I have had experience in programming from python (slightly related, html/css) and the computercraft from minecraff (basic i think it is).

My question is mainly about the C and past experience with the computercraft.

1. Is it possible to split the command console into 2 parts (a visual area and a text area)
2. Is it possible to use any form of pixel art or custom characters within any command console using C.

Visual C++ :: Changing Code From TCP To UDP

Mar 20, 2013

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);

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?

Visual C++ :: Merging Source Code Of Two Projects?

Oct 9, 2013

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.

Visual C++ :: Converting Code To CLI Form Application?

Jun 10, 2013

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.

Visual C++ :: Error / M4 Failed With Exit Code 255

Dec 8, 2013

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

Visual C++ :: HTTP Flood Code Ported To Bot Source?

May 6, 2013

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.

Visual C++ :: CryptUnprotectData Failing When Code Compiled On Windows 7?

Sep 24, 2012

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))
