Thread: CFile in MFC

i am having problems writing to a file. i am getting an access violation writing to the file. ive dug through the documentation for about an hour and i still cant figure out what im doing wrong.

here is my save code

Code:

void CChildView::SaveMap( CString path )
{
	CFile file;

	const int SizeOfBuffer = mapSz.x * mapSz.y;
	int * buffer = new int [ SizeOfBuffer ];

	int sizeBuffer[2];

	try 
	{
		file.Open( path, CFile::modeCreate );

		sizeBuffer[0] = mapSz.x;
		sizeBuffer[1] = mapSz.y;

		for ( int i = 0; i < mapSz.y; ++i )
		{
			for ( int j = 0; j < mapSz.x; ++j )
			{
				buffer[i * mapSz.x + j] = map[i][j];
			}
		}

		file.Write( sizeBuffer, 2 * sizeof(int));
		file.Write( buffer, SizeOfBuffer * sizeof(int));

	}

	catch (void)
	{
		MessageBox( "An error occured while writing to the file" );
	}

	delete [] buffer;

	file.Close();

	mapHasBeenEdited = FALSE;
	
}
