问题描述
喜。我想将类型PCWSTR转换为char * .tnx
hi. i want to convert type PCWSTR to char *.tnx
HWND hwnd;
CComHeapPtr spszLocation;
if (FAILED(GetBrowserInfo(svar.pdispVal, &hwnd,&spszLocation))) continue;
LPCWSTR tmp=static_cast(spszLocation);
size_t wcsChars = wcslen( tmp);
MD5 md5MdFive;
unsigned char ucMdfiveExit[16];
md5MdFive.ConvertMD5(spszLocation,(unsigned long)iDataSize,ucMdfiveExit);
std::wcout << hwnd<< L" "<< static_cast<PCWSTR>(spszLocation)<< std::endl;
是const unsigned char *但是我有LPCWSTR
in the code above the first parameter of the convertmd5 is const unsigned char * but i have LPCWSTR
推荐答案
wstring wstr( L"abcdef" );
int len = WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), wstr.size(), NULL, 0, NULL, NULL);
char* buffer = new char[len + 1];
WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), wstr.size(), buffer, len, NULL, NULL);
buffer[len] = '\0';
或特定于您的情况：
or to be specific to your case:
PCWSTR pstr(L"abcdef");
int len = WideCharToMultiByte(CP_ACP, 0, pstr, wcslen(pstr), NULL, 0, NULL, NULL);
char* buffer = new char[len + 1];
WideCharToMultiByte(CP_ACP, 0, pstr, wcslen(pstr), buffer, len, NULL, NULL);
buffer[len] = '\0';
