将数据从wchar *复制到cstring [英] copying data from wchar * to cstring

问题描述

我想知道如何将wchar *中的内容安全地复制到cstring.

wchar * buff =(wchar *)malloc(500);

cstring cbuff;

I want to know how to copy content from wchar * to cstring safely.

wchar *buff=(wchar*)malloc(500);

cstring cbuff;

How do I copy contents of buff into cbuff so that I can destroy buff?

推荐答案

cstring cbuff;

if(buff && (buff[0] != 0 ))
{
  cbuff = cstring(buff);
}

您尝试过以下方法吗:

Did you try this:

cbuff = (LPCWSTR)buff;

实际上我是在使用heapalloc分配内存的. 该程序导致访问冲突崩溃

但是可以使用malloc和free

Espen Harlinn和john我以两种方式尝试了..works(如果使用了malloc)，并且崩溃了，如果使用了heapalloc

actually i m allocating memory with heapalloc
the program crashes access violation

but works if used malloc and free

Espen Harlinn and john i tried in both ways ..works if used malloc and crashes if used heapalloc

WCHAR *buff=(WCHAR*)HeapAlloc(GetProcessHeap(),0,100);
//	 WCHAR *buff=(WCHAR*)malloc(100);
 wcscpy(buff,L"rajesh");
 CString cbuff;
 cbuff=CString(buff);
  // free(buff);
   HeapDestroy(buff);
