Problem with updating Mpqlib

[hamburger12]

Hello! I'm currently updating MPQLib for MoP. I got it working with the newest MPQ files excepted the files which have the flag "Incremental Patch".


Here is the part which fails:

System::Void MpqLib::Mpq::CFileStream::Open()
{
	System::Int32 BytesRead = 0;
	pin_ptr<HANDLE> HandlePointer = &_Handle;
	CStringHandle FileNameHandle(_FileName);

	if(_Archive == nullptr) throw gcnew System::InvalidOperationException("The file stream has no associated archive!");
	if(_Archive->IsDisposed) throw gcnew System::ObjectDisposedException(nullptr, "The archive of the file stream has been disposed!");
	if((_Archive->Handle == NULL) || (_Archive->Handle == INVALID_HANDLE_VALUE)) throw gcnew System::InvalidOperationException("The archive of the file stream has been closed!");

	if(!_Archive->FileExists(_FileName)) throw gcnew System::IO::FileNotFoundException("Could not find \"" + _FileName + "\"!", _FileName);


	if(!SFileOpenFileEx(_Archive->Handle, FileNameHandle.Value, 1, HandlePointer) && !SFileOpenFileEx(_Archive->Handle, FileNameHandle.Value, 0, HandlePointer)) throw gcnew System::IO::IOException("Unable to open \"" + _FileName + "\"!");
	

	DWORD length;
	SFileGetFileInfo(_Handle, SFILE_INFO_FILE_SIZE, &length, 4, NULL);
	_Length = length;
	if(_Length < 0) _Length = 0;

	_Cache->resize(static_cast<System::UInt32>(_Length));

	if(!SFileReadFile(_Handle, &((*_Cache)[0]), static_cast<DWORD>(_Length), reinterpret_cast<LPDWORD>(&BytesRead), NULL)) throw gcnew System::IO::IOException("Read operation failed with error: " + GetLastError());
	if(_Length != static_cast<System::Int64>(BytesRead)) throw gcnew System::IO::IOException("Read failed, expected " + _Length + " bytes, read " + BytesRead + " bytes!");

	_Position = 0;
}

At the end it fails with error code 38 which is end of file..

Do you got an idea what could be wrong with it?

Hey there, I am having the same issue with MpqLib for MoP with the incremental patch flag. Can you please post what you did to resolve it? Also, do you know of an updated MpqLib solution?

Thanks!
