Title: How to compile a .bat file? or write a simple .exe to call it?
Post by: banjo67xxx on November 28, 2009, 01:02:43 PM

Hi,

I'm trying to intercept calls to a .exe to trace them (legit as my company wrote the .exe) as part of debugging, and I've suceeded in writing a short .bat file which does what I want after renaming the original command with -ORIG.

the-command.bat

Code: [Select]

@echo off
echo .|time >> logfile.txt
echo %0 %* >> logfile.txt
the-command-ORIG.exe %*

The problem is that the customer's program is expecting to call the-command.exe not the-command.bat.

I tried renaming the .bat file, but then it won't execute.
I tried creating a shortcut with .exe extension to the .bat but that didn't work either.

Is there a compiler I could use to convert it from .bat to .exe?
or do I need to write a one-line program to call the .bat and compile it?
or would it be a whole lot easier to write a C program to do the tracing instead?

I've nearly solved it with MinGW and the following code

Code: [Select]

#include <unistd.h>
#include <stdio.h>

main(int argc, char *argv[])

{
  argv[0] = "C:\\path\\etc\\the-command.bat";
  execv("C:\\path\\etc\\the-command.bat", argv);
  return 0;
}
I'll follow up on the final problems in the programming forum.
