LPWSTR与LPCWSTR由此产生,它们的含义类似于LPSTR与LPCSTR,只是字符数据是16位的wchar_t而不是char。 然后为了实现两种编码的通用,提出了TCHAR的定义: 如果定义_UNICODE,声明如下: typedefwchar_t TCHAR; 如果没有定义_UNICODE,则声明如下: typedefchar TCHAR; LPTSTR和LPCTSTR中的含义就是每个字符是这样的TCHAR。 CStrin...

LPCTSTR is just a typedef that changes to LPCSTR if you don't #define UNICODE, or it could be LPCWSTR if you #define UNICODE. My first guess here is that you have never heard about this before, and I'll tell you what I always tell people trying to program for Windows: Understand how...
A cast of a string literal does nothing to the string, so writing something like: void SomeFunc ( LPCWSTR widestr ); main() { SomeFunc ( (LPCWSTR) "C:\\foo.txt" ); // WRONG! } will fail 100% of the time. It will compile, because the cast overrides the compiler's type-...

This is very unfortunate, because in reality aBSTRisnotthe same as a Unicode string.That typedef defeats type-checking and allows you to freely mixLPOLESTRs andBSTRs.Passing aBSTRto a function expecting aLPCOLESTR(orLPCWSTR) is safe,however the reverse is not. Therefore, it's important to be...
