const char *转wstring 方法

直接调用下列方法，输入参数即可转换

wstring InjectDll::charToWstring(const char* szIn)
{
	int length = MultiByteToWideChar(CP_ACP, 0, szIn, -1, NULL, 0);
	WCHAR* buf = new WCHAR[length + 1];
	ZeroMemory(buf, (length + 1) * sizeof(WCHAR));
	MultiByteToWideChar(CP_ACP, 0, szIn, -1, buf, length);
	std::wstring strRet(buf);
	delete[] buf;
	return strRet;
}
