U can set its value to the maximum positive value of int or to the available memory.

WCHAR* InputText = ( WCHAR* ) HeapAlloc( GetProcessHeap( ), HEAP_GENERATE_EXCEPTIONS, 5 * 1024 * 1024 );

Not many people read the whole file into a buffer. As we say, this solution doesn't scale. Most people read text files, line by line... only buffering what they need. If you're writing a text editor... it's a different story... and in that case you should dynamically allocate the text file buffer.

Why not use a std::wstring object instead?
