well, first of all, i did mean parameters in the WinExec() function..
second, i've altered my code to set asid memory (at least that's what i think i've done

)

(Toggle Plain Text)

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

int main(void)
{
 int bufsize=256;
 char *buffer=malloc(bufsize);
 while(1)
 {
  printf("\nCommand:>");
  WinExec(buffer,SW_SHOW);
  scanf("%s",buffer);
 }  
 return 0;
}

third,
Ooble, i don't really understand what you mean by

Quote:

If there are quote marks encompassing the path, separate the path from the arguments by using two different variables ("path" and "args" are probably your best choices). If not, first check the entire string isn't a file by opening it for reading and checking the return value (look at fopen() ). If it is, execute it. Otherwise, assume the path is the entire string up to the first space. Separate the path and the arguments and add quotes round the path.

Finally, do this:

(Toggle Plain Text)

run = strcat(0x20, path); run = strcat(args, run); WinExec(run, SW_SHOW);

run = strcat(0x20, path); run = strcat(args, run); WinExec(run, SW_SHOW);

i know how the function fopen() works, but how can i make the difference between a path and a parameter like : cd c:\windows\ or control userpasswords?

thanks for the help

, i really appreciate it!

So WinExec("control userpasswords") doesn't work?

not with the above code.. perhaps it does work with your code added, but like i said, i don't really understand what you mean..
this is what you see:

Quote:

Command:>control userpasswords

and then the output is:

Quote:

Command:>
Command:>

while typing "control userpasswords" in the command line pops up the account part of the control panel (like it should

)

Lemme try and simplify that. If there are quotes round the path, execute it as normal. If there aren't, first check to see if the entire string is a file. If it isn't, add quotes around the first argument (up to the first space), then execute it.

First off, the reason you are getting this:

Command:>
Command:>

Is because you are executing a blank buffer. You call WinExec with buffer
before buffer is defined.

...
printf("\nCommand:>");
WinExec(buffer,SW_SHOW);
scanf("%s",buffer);
...

Try this:

printf("\nCommand:>");
scanf("%s",buffer);
WinExec(buffer,SW_SHOW);

To pass parameters to your menu... enclose the whole string in double qoutes ("myCommand myParam1 myParam2").

Make that one change... then type at your prompt type this...

Command:>"control userpasswords"

That will work for you, it brings up the userpasswords option of my control panel.

huh, don't know why i've missed that, i know the scanf should be before the execution, must have switched it while trying to alter the code

thanks for it, but as for the "control userpasswords", it doesn't work, not even after changing the scanf location to before the winexec location (like you said), i still only get the control panel....

did you use the above code to get the userpanel of control panels?

>>Ooble, it sounds easy, but i have NO IDEA how to code that

, perhaps i need to read more manuals on strings, arrays etc....

Get C For Dummies, Volume 2 out of the library. Contains a lot of info on strings and pointers.
