如何将数据从unsigned char指针复制到LPCTSTR？ [英] How to copy data from unsigned char pointer to LPCTSTR ?

问题描述

是否可以将数据从



无符号字符指针复制到LPCTSTR？





LPCTSTR pBuf;



pBuf ia指向共享内存的指针每当我写内存时，我都会将pBuf增加4.



我只想将指针（pBuf）重置为初始位置（addr）at某点。



有谁知道怎么做？

Is it possible to copy a data from

unsigned char pointer to LPCTSTR ??


LPCTSTR pBuf ;

pBuf ia a pointer for shared memory ,whenever I do the memory write , I'll increment the pBuf by 4.

I just want to reset the pointer(pBuf) to initial position(addr) at some point.

Does anybody know How to do that ??

推荐答案

不可能使用 LPCTSTR varaibale。它是const（ L ong P ointer C on T CHAR Str ：它的类型为 const TCHAR * ）。当尝试将数据复制到这样的指针时，编译器将生成错误。



但是您可以分配初始指针值（重置指针）或将其转换为另一个指针非const变量（你应该知道在将const转换为非const时你在做什么）。



你应该详细解释你想做什么和你要复制什么类型的数据。

It is not possible using the LPCTSTR varaibale. It is const (Long Pointer Const TCHAR String: it is of type const TCHAR *). The compiler will generate an error when trying to copy data to such a pointer.

But you can assign the initial pointer value (reset the pointer) or cast it to another non-const variable (you should really know what you are doing when casting const to non-const).

You should explain with more detail what you want to do and what kind of data you want to copy.
