Enable white spaces when writing inputted strings to a text file

January 7, 2016, 8:18 pm

When I used a simple code example from my text book:

Code:
//This program writes user input to a file.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
    ofstream outputFile;//create object for writing data to file
    string name1, name2, name3;

    //open an output file:
    outputFile.open("Friends.txt");

    //Get the names of three friends:
    cout << "Enter the names of three friends.\n";
    cout << "Friend 1: ";
    cin >> name1;
    cout << "Friend 2: ";
    cin >> name2;
    cout << "Friend 3: ";
    cin >> name3;

    //Write the names to the file:
    outputFile << name1 << endl;
    outputFile << name2 << endl;
    outputFile << name3 << endl;
    cout << "The names were saved to a file.\n";

    //Close the file:
    outputFile.close();

    system("pause");
    return 0;
}
This is how the program reacted to the white space in the string "Angry Grandpa":
Name: WhitespaceError.jpg Views: 57 Size: 23.4 KB

How do I fix this behavior, so that a white space is allowed (for both my friends' first and last name to be seen as one string)?

Okay i have a problem i coded this cos i wanted to test something Like a Builder and Stub and that has been one of my major nightmares these days

My question goes like this i have an application (Which is the stub), its suppose to gather information and send vis Wininet like this

Code:
**stub.cpp**

#include <stdio.h>
#include <stdlib.h>
#include <Windows.h>
#include <Wininet.h>

#pragma comment(lib, "wininet.lib")

int main()
{
    char fullname,tel,email[250];
    printf("Enter First name: \n");
    scanf("%s",&fullname); 
    printf("Enter Telephone: \n");
    scanf("%s",&tel);
    printf("Enter Email: \n");
    scanf("%s",&email);

    static TCHAR hdrs[] =
      _T("Content-Type: application/x-www-form-urlencoded");
  static TCHAR frmdata[] =
      _T("fullname=fullname&tel=telephone&Email=&email");
  static LPSTR accept[2]={"*/*", NULL};

    HINTERNET hSession = InternetOpen("MyAgent",INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
        HINTERNET hConnect = InternetConnect(hSession, _T("ServerNameHere"),INTERNET_DEFAULT_HTTP_PORT, NULL, NULL,INTERNET_SERVICE_HTTP, 0, 1);
  HINTERNET hRequest = HttpOpenRequest(hConnect, "POST",_T("FormActionHere"), NULL, NULL, accept, 0, 1);
  HttpSendRequest(hRequest, hdrs, strlen(hdrs), frmdata, strlen(frmdata));

//Internet close For others here

    return 0;
}
Now here is the Builder which i would use to load the stub

Code:
Builder.cpp

#include <stdio.h>
#include <stdlib.h>
#include <Windows.h>

#include "resource.h"

int main()
{
    char url[50];
    printf("Enter URL: \n");
    scanf("%s",&url);

    // Extract file from Resource

    HRSRC hrsrc = FindResource(NULL, MAKEINTRESOURCE(wResId) , IDC_FILE1);
    HGLOBAL hLoaded = LoadResource( NULL,hrsrc);
    LPVOID lpLock =  LockResource( hLoaded);
    DWORD dwSize = SizeofResource(NULL, hrsrc);
    HANDLE hFile = CreateFile  (lpszOutputPath,GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
    DWORD dwByteWritten;
    WriteFile(hFile, lpLock , dwSize , &dwByteWritten , NULL);
    CloseHandle(hFile);
    FreeResource(hLoaded);


    MessageBoxA(NULL, "Done :)", "", MB_OK);


    return 0;
}
Now here goes my question, I want the file to load the other file in resource, the localhost part works fine, but i want it this time to use the domain which is online other than the localhost. This has been givving me issues and i need help to fix it. kindly help someone.

PS: I am typing from a mobile as i didnt use a compiler :)

Defining operators for vectors of templates

I'm reading Programming Principles and Practice Using C++ first edition first printing book. This book is really hard for beginners but I have studied it until chapter 19 and should finish it!

I have a problem with a drill in chapter 19. Please look at it in the link below.
http://uploads.im/S0mun.png

I have written the following code for questions number 1 through 13 of that drill but I have problems with the question number 14 of it.
There is no guide/sample on/of it in the chapter! So I don't know how to solve it. :(

Code:
#include <iostream>
using namespace std;

template <class T> class S {
public:
        T val;
        S(T v) { val = v; }
        T& operator[](int);
        const T& operator[](int) const;
};

//-----------------------------------------

template<class T> T& S<T>::operator[](int n) { 
        return val[n];
}

//---------------------------------------------------

template<class T> const T& S<T>::operator[](int n) const { 
        return val[n];
}

//--------------------------------------------------------

template <class T> istream& operator>>(istream& i_s, S<T>& v_i) {
        return i_s >> v_i.val;
}

//--------------------------------------------------

template <class T> ostream& operator<<(ostream& o_s, const S<T>& v_o) {
        return o_s << v_o.val;
}

//---------------------------------------

template <class T> ostream& operator<<(ostream& o_s, const S<vector<T>>& v_o) {
        return o_s << v_o.val;
}

//---------------------------------------

template<class T> void read_val(T& v) {
        cin >> v;
}

//-------------------------------

template<class T> void write_val(const T& v) {
        cout << v << '\n';
}

//-----------------------------------------

template<class T> void write_val(const vector <T>& v) {
        for(int i=0; i<v.size(); i++)
                cout << v[i] << ' ';
        cout << endl;
}

//------------------------------------

int main() 
{
        vector<int> vs;
        for(int i=0; i<5; i++)
                vs.push_back(i*i);

        S<int> s1(5);
        S<char> s2('c');
        S<double> s3(5.25);
        S<string> s4("Template");
        S<vector<int>> s5(vs);
   
        write_val(s1);
        write_val(s5);
       
        return 0;

}
The program runs successfully until write_val(s1); but facing write_val(s5); I get this error:

Error 1 error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const Vector<T>' (or there is no acceptable conversion) c:\users\me\documents\visual studio 2012\projects\test1\test1\test1.cpp 39

Please don't use friend feature. I haven't learnt it so far and likely I will learn it the next chapters of the book. :)
Thanks in advance.

I want to display Logo on my document like other data which I retrieve from database are store into variable and then those are passes to print on document. I am storing path of related bitmap in database and it is also retrieve into variable I know following:

// MAKEINTRESOURCE(IDB_BITMAP4),
MAKEINTRESOURCE(IDB_BITMAPNAME),
IMAGE_BITMAP,
0,

IDB_BITMAPNAME is a BITMAP which File Name Property set to the logo's path.

This is a static way to do means I already set FileName Property of BITMAP. I want to set it at runtime. please help


I tried as follows but not work,

hbit = (HBITMAP) LoadImage(NULL,
// MAKEINTRESOURCE(IDB_BITMAP4),
sLogopath,
IMAGE_BITMAP,
0,
0,
LR_LOADFROMFILE);

sLogoPath is CString type variable which contain C:\Users\Administrator\Desktop\cg_logoa.bmp path of bitmap

I also tried for dilectly mention path instead of variable "C:\\Users\\Administrator\\Desktop\\cg_logoa.bmp"

Also tried for this

L"C:\\Users\\Administrator\\Desktop\\cg_logoa.bmp" but it gives following error

How to link a static library struct to a user app ?

Using a struct object can be quite useful to combine several different data types into a single package. I have tried to do this utilizing a static library, but have run into problems. The main problem is to get the calling app to access the library struct. I have attached a small demo to illustrate the problem. Any help greatly appreciated. Thanks.

I'm trying to implement rebooting of a remote computer with InitiateShutdown API using the following code, but it fails with RPC_S_SERVER_UNAVAILABLE or 1722 error code:

//Process is running as administrator

    //Receive nErrorCode == 1722, or RPC_S_SERVER_UNAVAILABLE
}



BOOL AdjustPrivilege(LPCTSTR pStrMachine, LPCTSTR pPrivilegeName, BOOL bEnable)
{
    HANDLE hToken;
    TOKEN_PRIVILEGES tkp;
    BOOL bRes = FALSE;

    if(!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
        return FALSE;

    if(LookupPrivilegeValue(pStrMachine, pPrivilegeName, &tkp.Privileges[0].Luid))
    {
        tkp.PrivilegeCount = 1; 
        tkp.Privileges[0].Attributes = bEnable ? SE_PRIVILEGE_ENABLED : SE_PRIVILEGE_REMOVED;

        bRes = AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);

        }
    }

    CloseHandle(hToken);

    return bRes;
}
192.168.42.105 computer has file and printer sharing enabled on the network.

Note that the following shutdown command seems to work just fine to reboot the remote computer:

Passing a struct to and from a DLL

January 19, 2016, 7:06 pm
$

I have a DLL that uses a struct that is defined in a separate file, misc.h.
Code:
// misc.h
typedef struct
{
        wstring wsvarstr;
        wstring wsvarnam;
        TNT::Matrix<double> Mf;
        vector<int> vndim;
        vector<wstring> vwsdxs;
} sTensor;
The DLL header:
Code:
#include "misc.h"


extern "C"
{
        void TAIP_API StartMyLib();
        void TAIP_API DumpTensor(sTensor st);
        void TAIP_API PrintTensor(sTensor st);
        void TAIP_API SetTensor(sTensor * st);
        int TAIP_API ReadVariableMap(wchar_t * varfilepath);
        void TAIP_API DumpVariableMap();
        int TAIP_API GetTensorVariable(wstring wsvarnam, sTensor &tensor);
        void TAIP_API ListVariables();
        void TAIP_API ListVarStrings();

}
The DLL methods utilize a class, CVarStack that also uses misc.h to define the struct sTensor.

What is remarkable to me is that this works at all, but it does. Quite nicely, in fact. Without compiler warnings,
errors, or leaks.

My understanding of DLLs is that one should not (cannot ?) pass reference objects as input parameters. In addition,
C-Linkage prohibits stl input parameters such as wstring and the presumably the stl contents of the struct.

My questions are:
1 - Why does this code work on VS 2010, VS2015 (Win 7 64-bit)?
2 - Can this code be relied upon to work on other Windows machines (Win2K, Vista, Win8, Win10) ?

Thanks for your comments.
