Ako je u pitanju Windows onda....

ShellExecute()-Izvod iz Helpa:
==============================
The ShellExecute function opens or prints a specified file. The file can be an executable file or a document file.
....

HINSTANCE ShellExecute(
HWND hwnd, // handle to parent window
LPCTSTR lpOperation, // pointer to string that specifies operation to perform
LPCTSTR lpFile, // pointer to filename or folder name string
LPCTSTR lpParameters, // pointer to string that specifies executable-file parameters
LPCTSTR lpDirectory, // pointer to string that specifies default directory
INT nShowCmd // whether file is shown when opened
);

Evo ti par primera kako ih ja koristim (mozda ima i bolji nacin):
1. OTRVARANJE neke Help fajle sa InternetExplorerom:
//....
char HelpFile[MAX_PATH];
// pa negde u programu imas na primer:
strcpy(HelpFile,"c:\\My_dir\\My_Help.HTML");
//....
ShellExecute(NULL, "open", "IEXPLORE.EXE", HelpFile,NULL,SW_SHOWNORMAL);

2. Ili ako ces pozvati neki svoj program bez prosledjivanja parametara:
//....
char My_prog_exe[MAX_PATH];
// pa negde u programu imas na primer:
strcpy(My_prog_exe,"c:\\My_dir_exe\\My_prog_x.exe");
//....
ShellExecute(hwnd,NULL, My_prog_exe, NULL, NULL, SW_SHOWNORMAL);

Code:

#include <iostream>
using namespace std;

int main() {
    char putanja[50];
    strcpy(putanja,"c:\\avipreview.exe");

    system(putanja);

return 0;
}

Sasvim lepo radi.

ShellExecute() se preporucuje. System() ne radi sve sto treba da radi na Win*owsu... Naravno tu je i exec*() kompanija za ljude kojima treba neki drugi nacin.

ruku na srce meni i CreateProcess() jako lepo radi...cak ga i vise koristim nego ShellExec...a sto se tice exec-a (WinExec i ostalo) to se cisto koristi zarad kompatibilnosti sa 16-bitnim windozom... U principu za startovanje procesa najcesce se koriste ShellExecuteEx() i CreateProcess() jer pruzaju maximalnu kontrolu aplikacije koju zelis da pozoves...

Hm .. mislim da je leka mislio na neku drugu familiju exec* poziva :]]

Da, mislio sam na familiju exec*() sistemskih poziva, koji su tu, bice tu i ostace tu ako Microsoft zeli da prati standard(e) (jer se exec*() nalaze u vise standarda).

Usput jedno pitanje vezano za ovu temu:

Leka rece da system() ne radi sve kako treba. Da li je system() na Windowsu ekvivalent UNIX-ovom pozivu system(), tj. da li i on poziva CreateProcess() (posto UNIX-ov system() poziva fork() pa execv()) izvrsavajuci program iz zadate putanje ili je nesto drugo u pitanju ? Ako je to slucaj, onda ne vidim neopravdanost pozivanja system-a umesto CreateShell-a.

Zahvaljujem
