I want to set the current directory to the work directory (where the executable is located) but I can´t get it to work so far.
Even if I give the path name directly in the call, like eg:
SetCurrentDirectory("C:\bla\blabla\blaaaa");


This doesn´t work, also:
SetCurrentDirectory(work_dir);

I´ve tried to use a long as pointer to the string, but that doesn´t work either.

Please don´t laugh, I´m an absolute beginner when it comes to C.
I´m a littlebit confused by all the datatypes.
Can you help me out?

Code:

---

#include <direct.h>

void SetPathToExe(void)
{
    TCHAR  exePath[MAX_PATH+1] ;

   ::GetModuleFileName( ::GetModuleHandle(0), exePath, sizeof( exePath )-1 ) ;
   _chdir( exePath ) ;
}

---

Then just call 'SetPathToExe() ;'

"TCHAR" undeclared identifier - of course, it´s Lite-C.

When I use a char or a string insteat of a TCHAR, it shows me an syntax error at "::GetModuleFileName".

Ok. I forgot that we was in lite-C that code was from C. Sorry for that.
Here is the lite-C version.

Code:

---

#include <windows.h>
#include <stdio.h>
	
void SetPathToExe(void)
{    
      char  exePath[260+1] ; // MAX_PATH = 260
      GetModuleFileName( GetModuleHandle(0), exePath, sizeof( exePath )-1 ) ;   
      _chdir( exePath ) ;
}

---

I´ve used "char exePath = "#261";" because I´ve got an error when I use "char exePath[260+1] ;"
Result: No errors but it doesn´t seem to work.
Thanks for your help btw.

Ok.... next one to try then ...
I have added a verify ...

Code:

---

#include <windows.h>
#include <stdio.h>
#define MAX_PATH 260 
	
void SetPathToExe(void)
{    
	char  exePath[MAX_PATH] ; 
	
	GetModuleFileName( GetModuleHandle(0), exePath, (MAX_PATH-1) ) ;   
	_chdir( exePath ) ;
	
	// verify
	_getcwd(exePath, (MAX_PATH-1) ) ;
	printf( "%s\n", exePath ) ;
}

It shows me the directory where the latest file comes from - in my case a bmap, loaded through a file open dialog.
I need the actual work directory, the directory where the programm (my game or application) is located, regardless if it´s an exe or the development version.
I hope that I don´t have confused you by writing "engine path".

Ok. A slight missunderstanding from my side.
If I comes up with a solution I will write it here.
Haven't the time for it until later this evening, but
hopefully something could be done then ( I hope

Cheers

You deserve at least a cookie.

So... after some struggling here we are

This testcode switches to the executable directory,
then writes a file test.txt there.
