vc++,MfC ,cstring與char相互轉換知識

 

//mapName = mapString;//----------------------原始-
string mapName;

CString strtemp,strtemp2;
//char temp[XMAX_FILE_LENGTH + 1];
char temp[1024];

char print_internal_mapname_content[1024];

//數組可以賦值給cstring.   mapName=print_internal_mapname_content;
// 學習用cstring to chars,則需要寫代碼 cstringTochars(strtemp, temp);
//strcpy(print_internal_mapname_content,temp);數組之間用strcpy
//cstring 之間可以直接賦值 mapName = mapString;

void cstringTochars(CString str, char* chars)
{
#ifdef UNICODE
    int n = str.GetLength(); // n = 14, len = 18
    int len = WideCharToMultiByte(CP_ACP, 0, str, str.GetLength(), NULL, 0, NULL, NULL);
    WideCharToMultiByte(CP_ACP, 0, str, str.GetLength(), chars, len, NULL, NULL);
    chars[len+1] = '\0'; //多字節字符以'\0'結束
#else
    strcpy(chars, str);
#endif
