DLL Injection

[Marq77]

Hi i am trying to inject a 'named' dll to a specific window caption.Here is the source.


/*
* Loader.cpp
* -----------
* Dll process injecter.
*/

#include <windows.h>

#define DLL_NAME "zerocrack.dll"


#pragma comment ( lib, "Advapi32.lib" )
#pragma comment ( lib, "user32.lib" )

BOOL EnableDebugPrivledges( void )
{
HANDLE hToken;
LUID Luid;
TOKEN_PRIVILEGES tpToken;

// enable the SeDebugPrivilege
if( 0 != OpenProcessToken( GetCurrentProcess( ) ,TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken ) &&
0 != LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &Luid ) )
{
tpToken.PrivilegeCount = 1;
tpToken.Privileges[ 0 ].Luid = Luid;
tpToken.Privileges[ 0 ].Attributes = SE_PRIVILEGE_ENABLED;
if( 0 != AdjustTokenPrivileges( hToken, FALSE, &tpToken, sizeof( tpToken ), NULL, NULL ) ) {
CloseHandle( hToken );
return TRUE;
}
}
return FALSE;
}

INT WinMain( HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmdLine, INT nShowCmd )
{

HWND hwnd;
DWORD dwId;
HANDLE hProcess;
LPSTR lpFolder;
LPVOID lpMem;

EnableDebugPrivledges( );

hwnd = FindWindow("Warcraft III",NULL);


if ( NULL == hwnd )
{
MessageBox( 0, "Unable to find Warcraft III window", 0, 0 );
return 0;
}

GetWindowThreadProcessId( hwnd, &dwId );
hProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, dwId );

if ( NULL == hProcess )
{
MessageBox( 0, "Unable to open game process", 0, 0 );
}

if ( 0 == lpCmdLine[ 0 ] )
lpCmdLine = GetCommandLine( );

lpFolder = lpCmdLine;
if ( lpFolder[ 0 ] == '\"' )
{
lpFolder[ 0 ]++;
while( lpFolder++[ 0 ] != '\"' );
while( lpFolder--[ 0 ] != '\\' );
lstrcpy( lpFolder + 2, DLL_NAME );
lpFolder = lpCmdLine + 1;
}
MessageBox( 0, lpFolder, 0, 0 );

lpMem = VirtualAllocEx( hProcess, 0, lstrlen( lpFolder ) + 1, MEM_COMMIT, PAGE_READWRITE );
WriteProcessMemory( hProcess, lpMem, lpFolder, lstrlen( lpFolder ), NULL );

WaitForSingleObject(
CreateRemoteThread( hProcess, NULL, 0, ( LPTHREAD_START_ROUTINE )&LoadLibraryA, lpMem, 0, &dwId ),
INFINITE );

VirtualFreeEx( hProcess, lpMem, 0, MEM_RELEASE );


return 0;
}


my problem is,it compiles,but when i open it to inject the dll,a message box with the title "error' comes up and there is no message in the error box.Why isnt it injecting normally?
