Trouble with lpCmdLine

I've written this code, it looks for a file specified in the commandline and says YES if it exists or NO if it doesn't exist :

Code:

---

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


int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char * lpCmdLine, int  nCmdShow)

{
  WIN32_FIND_DATA FindFileData;
  HANDLE hFind;
  HANDLE Find;
 
  hFind = FindFirstFile(lpCmdLine[1], &FindFileData);
  if (hFind == INVALID_HANDLE_VALUE)
      printf("NO\n");
  else
      printf ("YES\n");

  system("PAUSE");       
  return 0;
}

It should be working but the compiler says :

13 [Warning] passing arg 1 of `FindFirstFileA' makes pointer from integer without a cast

I dont understand it because i'm passing it a char, not an int !
Someone can help me ?

I know i should write only lpCmdLine but i need to specify [1] and [2] in my program... so i need it :( (and i cant use argc because i need WINAPI WinMain coz it has to be an hidden application)

Thanx a lot :)

> I dont understand it because i'm passing it a char, not an int !
from the warning message, it looks like the compiler is looking for a pointer. So the compiler hasprobably cast to an int in a vain
attempt to sort out the problem for you.

Note that lpCmdLine is "Pointer to a null-terminated string
specifying the command line for the application, excluding the
program name. To retrieve the entire command line, use the
GetCommandLine function.".

It is not an array of strings like argv in:
int main (int argc, char * argv[])

EDIT : I was wrong.. dont read this post

nope ! because i wrote this one and it works :(

Code:

---

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


int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char * lpCmdLine, int  nCmdShow)
{
  printf("%s\n",lpCmdLine[1]);
  printf("%s\n",lpCmdLine[2]);
  system("PAUSE");       
  return 0;
}

I really dont understand what's wrong in the other code...damn me :(

... and what did you get out?

EDIT : I was wrong.. dont read this post

the first code, it is compiled but it crushes if it's executed!

the second one, works.. "myexe.exe hi world" i see "hi world" printed in the consolle...

But in the second code you are passing a char into a function that expects a char*
so I don't understand why that one should work at all.

Damn... I dunno what i saw... yes u r right it crushes the same as the first one...
I think I was confused, it was the argv program that worked...

So do u think there is no way to read more than one param. form lpCmdLine?

try this:

Code:

---

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

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char * lpCmdLine, int  nCmdShow)
{
  printf("%s\n",lpCmdLine);
  system("PAUSE");       
  return 0;
}

You should get what you wanted to from your second program.
So now all (!) you have to do is split up your commmand line string using something
like strtok() or similar and pass the file name correctly into your FindFirstFile() function

good idea about strtok() , i will study on it and post my (I hope) working program ;)

oky it is not optimized but i'm on the right way ;) it works, thanx for ur help

Code:

---

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


 
  char separatori[]  = " ";
  char *token;

  int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char * lpCmdLine, int  nCmdShow)

 {
    token = strtok( lpCmdLine, separatori );
    printf( "%s\n", token );
    token = strtok( NULL, separatori );
    printf( "%s\n", token );
 
    system("PAUSE");       
    return 0;
 }
