char*转为LPCWSTR

具体代码：

    char name[256] = {0};
    //function(name);

	WCHAR wszClassName[256];
	memset(wszClassName,0,sizeof(wszClassName));
	MultiByteToWideChar(CP_ACP,0,name,strlen(name)+1,wszClassName,
		sizeof(wszClassName)/sizeof(wszClassName[0]));

    MessageBox(NULL, wszClassName, L"Test", 0);
