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...
///cstring TO char *charpoint=strtest.GetBuffer(strtest.GetLength()); (3) 标准C里没有string,char *==char []==string, 可以用CString.Format(”%s”,char *)这个方法来将char *转成CString。 要把CString转成char *,用操作符(LPCSTR)CString就可以了。 CString转换 char[100] chara[100]; CString...
其中LP的含义是长指针(long pointer),C的含义是常量(constant),W的含义为宽字符(wchar_t),T的含义为_T宏. LPSTR:一般长指针,可以与char*互换使用 LPTSTR:根据是否定义UNICODE来解释的长指针 LPWSTR:宽字符长指针,使用UNICODE编码 LPCSTR:常量长指针,表明这种实例的内容无法被改变 ...

标准C里没有string,char *==char []==string 可以用CString.Format("%s",char *)这个方法来将char *转成CString。 要把CString转成char *,用操作符(LPCSTR)CString就可以了。 CString-> char[100] char a[100]; CString str("aaaaaa"); strncpy(a,(LPCTSTR)str,sizeof(a)); ...
1. LPCTSTR 实际上就是字符串，不过是会根据当前的字符集进行自适应：如果是ANSI的话，LPCTSTR = const char* ，如果是Unicode的话，LPCTSTR = const wchar_t*。其实这是windows下的命名方式，你把它的名字拆开了看就很清晰：LP：长指针，C：const，T：自适应，STR：字符串。类似的还有LPCSTR、LPSTR...
CString.Format("%s", string.c_str());用c_str()确实比data()要好.2.char -> string string s(char *);你的只能初始化，在不是初始化的地方最好还是用assign().3.CString -> string string s(CString.GetBuffer());GetBuffer()后一定要ReleaseBuffer(),否则就没有释放缓冲区所占的空间.《C++标准函数...
