Question

error C2664: “strcpy”: 不能将参数 2 从“CString”转换为“const char *”

CString sCaption;
GetWindowText(sCaption); // get label text
char* szCap=NULL; // char buffer
int iLen=sCaption.GetLength(); // buffer size
szCap=(char*)malloc(2+iLen); // allocate buffer
if (szCap==NULL) return; // allocation failure
strcpy(szCap,sCaption); // copy text to buffer
szCap[iLen]=' '; // ensure the last char is a space
szCap[1+iLen]='\0';
char* tokenpos;
项目从多字节转到使用 Unicode 字符集，出现上述错误，要如何修改呢？？？

Answer 1

#include<tchar.h>

CString sCaption;
GetWindowText(sCaption); // get label text
wchar_t* szCap=NULL; // char buffer
int iLen=sCaption.GetLength(); // buffer size
szCap=(wchar_t*)malloc(4+2*iLen); // allocate buffer
if (szCap==NULL) return; // allocation failure
wcscpy(szCap,sCaption); // copy text to buffer
szCap[iLen]=' '; // ensure the last char is a space
szCap[1+iLen]='\0';
wchar_t* tokenpos;
