passing arguments with shellexecute

-excuse me for my english -

i want to execute a program from an other with shellexecute and with passing multiple arguments, the problem is just the first argument is passed to the other ... what can i do :shout:?

the frist

Code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>



int main(int argc, char **argv)

{



    FILE * f;

    if(argc>1){





        f = fopen(strcat(argv[1],".txt"), "a");



        if (f != NULL)

        {

            printf("%s",argv[2]);

           fprintf(f, "%s^%s\n",argv[2],argv[3]);

            printf("qsdfs");

        }

        fclose(f);

        }

    else

        perror(argv[1]);

getch();

    return 0;

}

the second

Code:

#include <windows.h>

#include <shellapi.h>





int main ()

{



char **tab;

tab=(char**)malloc(3*sizeof(char*));

tab[0]=(char*)malloc(10*sizeof(char));

tab[1]=(char*)malloc(10*sizeof(char));

tab[2]=(char*)malloc(sizeof(char));



strcpy(tab[0],"films");

strcpy(tab[1],"the titanic");

strcpy(tab[2],"1h 45min");





ShellExecute(NULL,"open","insert.exe",tab,NULL,SW_SHOWDEFAULT);

  return 0;

}

Re: passing arguments with shellexecute

first of all parameters are separated by space.
so,when you pass "1h 45" as parameter ,you actually pass 2 parameters
1st="1h"
2nd="45"

i changed your code a lit bit.
===================

Code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include <conio.h>

int main(int argc, char **argv)

{



    FILE * f;

    for (int i=1;i<argc;i++) printf("\nparameter %d=%s",i,argv[i]);

    getchar();getchar();

    printf("\n");

    if(argc>1){





        f = fopen(strcat(argv[1],".txt"), "a");



        if (f != NULL)

        {

            printf("%s",argv[2]);

           fprintf(f, "%s^%s\n",argv[2],argv[3]);

            printf("qsdfs");

        }

        fclose(f);

        }

    else

        perror(argv[1]);

getch();

    return 0;

}

now when you run it ,the program tells you which parameters it received.

second change
==============

Code:



#include <windows.h>

#include <shellapi.h>

#include <stdio.h>





int main ()

{



char **tab;

tab=(char**)malloc(3*sizeof(char*));

tab[0]=(char*)malloc(10*sizeof(char));

tab[1]=(char*)malloc(10*sizeof(char));

tab[2]=(char*)malloc(sizeof(char));



strcpy(tab[0],"films");

strcpy(tab[1],"the_titanic");

strcpy(tab[2],"1h_45min");

char tabs[30]="\0";

strcat(tabs,tab[0]);

strcat(tabs," ");

strcat(tabs,tab[1]);

strcat(tabs," ");

strcat(tabs,tab[2]);

printf("\n%s",tabs);

getchar();

getchar();

ShellExecute(NULL,"open","insert.exe",tabs,NULL,SW_SHOWDEFAULT);

  return 0;

}

in this code i put an underscore ("_") instead of space in order to have 1 parameter instead of 2.

then i create one string with your parameters separated by space in variable tabs
which i pass to insert.exe program.
