您好,我正在使用 UNICODE 和 /clr 在 Visual C++ 2010(西班牙语)中编程。我有一个名为“fileFuncs.h”的头文件:
#include <iostream>
#include <fstream>
#include <string>
#include <stdlib.h>
#include <string>
using namespace std;
std::wstring s2ws(const std::string& s)
{
int len;
int slength = (int)s.length() + 1;
len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0);
wchar_t* buf = new wchar_t[len];
MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len);
std::wstring r(buf);
delete[] buf;
return r;
}
void callSystem(string sCmd){
std::wstring stemp = s2ws(sCmd);
LPCWSTR params = stemp.c_str();
ShellExecute(NULL,L"open",L"c:\\windows\\system32\\cmd.exe /S /C ",params,NULL,SW_HIDE);
}
但是当我编译时给我这些错误:
错误 LNK2028:指的是未解析的符号(令牌)(0A0004A5)“extern "C" struct HINSTANCE__ * stdcall ShellExecuteW(struct HWND *,wchar_t const *,wchar_t const *,wchar_t const *,wchar_t const *,int)”(?

是某种配置吗?
