LPCTSTR is a windows typedef. It stands for Long Pointer to a Constant T String. A T string is a null terminated array that is of WCHARs when UNICODE is defined and CHARs when UNICODE is not defined.

You probably aren't. Here's a way to check: do a sizeof(TCHAR) somewhere in your program and see what it spits out. If the result is 1 then you probably don't have UNICODE defined.

I did get a 1. How do I define it?

I got that fixed but I dont think it will fix my problem.

I need to load LPCTSTR lpName from ifstream fin(filename);

Do I make filename a char, a string or what ?

Before you include a Windows-related headers, #define UNICODE.

Of course, the question is whether you want to define UNICODE: are your text assets in UNICODE, MBCS or ASCII?

As for loading data into an LPCTSTR using std::ifstream, if you're not using UNICODE then it's the same as loading into a char * buffer and passing that buffer to the function with LPCTSTR parameter. Alternately - and, frankly, better - load the data into a std::string and pass the return value of std::string::c_str() to the legacy (probably Win32 API) function that needs an LPCTSTR.
