BSTR转QString

BSTR 转 QString

方法一：

QString Demo::bstrToqstring(BSTR bstr)
{
    char buf[260] = { 0 };
    int len = WideCharToMultiByte(CP_ACP, 0, bstr, wcslen(bstr), NULL, 0, NULL, NULL);
    WideCharToMultiByte(CP_ACP, 0, bstr, wcslen(bstr), buf, len, NULL, NULL);
    return QString(buf);
}

方法二：

// 获取并显示友好名称
WCHAR *aa = EloamGlobal_GetFriendlyName(1, 0);
QString s = QString::fromWCharArray(aa);
