[C++] Risalire alla cartella di Acrobat Reader

[valer_85]

ciao a tutti, premetto ke d c++ nn so niente, ma mi serve il vostro aiuto x un piccolo eseguibile da rikiamare da un prog java... ecco il codice:

#include <iostream>
#include <windows.h>
#include <fstream>

using namespace std;

/*------------------| getExeName |--------------------------------*
| Description:
| ~~~~~~~~~
| Returns the string after the last "\"
\*-----------------------------------------------------------------*/
string getExeName(string strFullPathToExe) {
    int Position = strFullPathToExe.find_last_of("\\");
    strFullPathToExe = strFullPathToExe.erase(0, Position +1);

    return strFullPathToExe;
}

int ExecuteProcess(string &FullPathToExe, string &Parameters, int SecondsToWait) {
    int iMyCounter = 0, iReturnVal = 0;
    DWORD dwExitCode;

    /* - NOTE - You could check here to see if the exe even exists */

    /* Add a space to the beginning of the Parameters */
    if (Parameters.size() != 0 ) { 
        Parameters.insert(0," ");
    }

    /* When using CreateProcess the first parameter needs to be the exe itself */
    Parameters = getExeName(FullPathToExe).append(Parameters);

    /* The second parameter to CreateProcess can not be anything but a char !!
        Since we are wrapping this C function with strings, we will create
        the needed memory to hold the parameters  */

    /* Dynamic Char */
    char * pszParam = new char[Parameters.size() + 1];

    /* Verify memory availability */
    if (pszParam == 0) {
        /* Unable to obtain (allocate) memory */
        return 1;
    } 
    const char* pchrTemp = Parameters.c_str();
    strcpy(pszParam, pchrTemp);

    /* CreateProcess API initialization */
    STARTUPINFO siStartupInfo;
    PROCESS_INFORMATION piProcessInfo;
    memset(&siStartupInfo, 0, sizeof(siStartupInfo));
    memset(&piProcessInfo, 0, sizeof(piProcessInfo));
    siStartupInfo.cb = sizeof(siStartupInfo);

    /* Execute */
    if (CreateProcess(FullPathToExe.c_str(), pszParam, 0, 0, false,
                      CREATE_DEFAULT_ERROR_MODE, 0, 0, &siStartupInfo,
                      &piProcessInfo) != false) { 
       /* A loop to watch the process. Dismissed with SecondsToWait set to 0 */
       GetExitCodeProcess(piProcessInfo.hProcess, &dwExitCode);

       while (dwExitCode == STILL_ACTIVE && SecondsToWait != 0) {
           GetExitCodeProcess(piProcessInfo.hProcess, &dwExitCode);
           Sleep(500);
           iMyCounter += 500;

           if (iMyCounter > (SecondsToWait * 1000)) 
           { 
               dwExitCode = 0;
           } 
       }
       
       if (!TerminateProcess(piProcessInfo.hProcess, 0)) {
          cout << "Errore nella terminazione di AcrobatReader" << endl;
       }
    }
    else {
        /* CreateProcess failed. You could also set the return to GetLastError() */
        iReturnVal = 2;
    }

    /* Release handles */
    CloseHandle(piProcessInfo.hProcess);
    CloseHandle(piProcessInfo.hThread);

    /* Free memory */
    delete[]pszParam;
    pszParam = 0;

    return iReturnVal;
}

int main() {
   string percorso = "C:\\Programmi\\Adobe\\Acrobat 5.0\\Reader\\AcroRd32.exe";
   string parametri = "";

   ifstream f("lista.txt");
   string str;

   while(getline(f, str)) {
      parametri = parametri.append(str);
      ExecuteProcess(percorso, parametri, 5);
      parametri = "";
   }
   
   return 0;
}

il mio problema è ke in questo codice la cartella in cui risiede acrobat è già definita, ma potrebbe succedere ke x un altro utente sia diversa...come faccio a risalire alla cartella in base al pc nel quale viene eseguito il programma? grazie
