LPCWSTR stands for “Long Pointer to Constant Wide String”. The W stands for Wide and means that the string is stored in a 2 byte character vs. the normal char. Common for any C/C++ code that has to deal with non-ASCII only strings.=
To get a normal C literal string to assign to a LPCWSTR, you need to prefix it with L
LPCWSTR a = L"TestWindow";
