Hi guys,

I have a runxbe(); class.

All the app does is boot another .xbe at the moment.. Can anyone help getting this to work..

heres the launch.cpp:
Code:
#include "launch.h"

#include <stdio.h> // sprintf(..)
/*
Description: Launch another XBE by unmounting then remounting D:

Detail:
If you want to launch another XBE (say you have a menu program) - you
have to first map the D: drive to the location of the XBE you are launching
or else it won't be able to find its media files.

You have to first unmount the D: drive, then re-mount it to the correct
device and subdirectory. Then simply call your XBE.
*/
 

#ifdef _XBOX

// Hidden Kernal Functions
#define IN
typedef struct _UNICODE_STRING {unsigned short Length; unsigned short MaximumLength; PSTR Buffer;} UNICODE_STRING,*PUNICODE_STRING;
extern "C" XBOXAPI DWORD WINAPI IoCreateSymbolicLink(IN PUNICODE_STRING SymbolicLinkName,IN PUNICODE_STRING DeviceName);
extern "C" XBOXAPI DWORD WINAPI IoDeleteSymbolicLink(IN PUNICODE_STRING SymbolicLinkName);
extern "C" XBOXAPI DWORD WINAPI XapiMapLetterToDirectory(IN LPCSTR pcDriveString,IN LPCSTR pcPathString,IN DWORD pcszTitleId,IN bool fCreateDirectory,IN LPCSTR pcszTitleName,IN bool fUpdateTimestamp);

// Unmount the old D: drive
static void UnmountD()
{
   char szDestinationDrive[16];
   strcpy(szDestinationDrive,"\\??\\D:");

   UNICODE_STRING LinkName = {
   strlen(szDestinationDrive),
   strlen(szDestinationDrive) + 1,
   szDestinationDrive};

   IoDeleteSymbolicLink(&LinkName);
}

// Mount the D: drive to a given device and directory
// szDevice = "Cdrom0" or "Harddisk0\Partition6"
// szDir = "" or "Game1"
static void MountD(char* szDevice, char* szDir)
{
   char szSourceDevice[256];
   char szDestinationDrive[16];

   strcpy(szDestinationDrive,"\\??\\D:");
   sprintf(szSourceDevice,"\\Device\\%s",szDevice);
   if (*szDir != 0x00 && *szDir != '\\')
   {
      strcat(szSourceDevice, "\\");
      strcat(szSourceDevice, szDir);
   }

   UNICODE_STRING LinkName = {
      strlen(szDestinationDrive),
      strlen(szDestinationDrive) + 1,
      szDestinationDrive
      };
   UNICODE_STRING DeviceName = {
      strlen(szSourceDevice),
      strlen(szSourceDevice) + 1,
      szSourceDevice
      };

   IoCreateSymbolicLink(&LinkName, &DeviceName);
}

// szDevice = the device where the XBE is "Cdrom0"
// szDir = the subdirectory where your xbe is "Games\Game1"
// szFile = the name of your XBE (without the path) - "Game1.xbe"
void RunXbe (char* szDevice, char* szDir, char* szFile)
{
   char szXbePath[64];
   wsprintf(szXbePath,"D:\\",szFile);

   UnmountD();
   MountD(szDevice, szDir);
   XLaunchNewImage(szXbePath, NULL );
}


#else

void RunXbe (char* szDevice, char* szDir, char* szFile)
{
   //Start a standard exe here for pc version :)
}

#endif //_XBOX


and heres the launch.h:
Code:
#pragma once



#ifdef _XBOX

#include <xtl.h>

#else

// Where using DirectX
#pragma comment(lib, "D3d8.lib") // DirectX 8
#pragma comment(lib, "D3dx8.lib")
#include <d3dx8.h>

#endif //_XBOX



// szDevice = the device where the XBE is "Cdrom0"
// szDir = the subdirectory where your xbe is "Games\Game1"
// szFile = the name of your XBE (without the path) - "Game1.xbe"
void RunXbe (char* szDevice, char* szDir, char* szFile);




Now i call the function no problems at all and can pass my variables accross but i get a error. .xbe could not be booted.. I know its something so small.. any whizzes around?? Im not that bad a coder on xbox but this ones got me stumped..

Heres how i call it:
Code:
RunXbe ("Cdrom0", "", "install.xbe"); // lets launch ourself
   
   // szDevice = "Cdrom0" or "Harddisk0\Partition6" (where xbe is)
// szDir = the subdirectory where your xbe is "Games\Game1"
// szFile = the name of your XBE (without the path) - "Game1.xbe"


Im just trying to call another xbe for a test.. Its really the same app at the moment!

anyway, thanks for any help guys,
