安装Visual Studio 2010 Service Pack 1时,出现此错误:

安装没有成功.尚未安装Microsoft Visual Studio 2010 Service Pack 1,原因是:
通用信任失败.

如何安装Service Pack 1？我使用的是Windows 7 32位.

这是日志文件:

我几乎是android的新手.现在,我想构建一个应用程序,它将在我的手机和Windows PC之间创建远程访问.我正在寻找一些建议.如果你们可以通过提供一些关于我应该做什么或者我应该学习什么的提示来帮助我,这将是一件非常愉快的事情.

我正在添加一个GridView,然后从SQL Server数据库中显示数据.问题是GridView没有在带有或没有数据的浏览器中显示.

这是我的代码:

<asp:GridView ID="GridAllStore"  runat="server" AutoGenerateColumns="False" Width="100%"  ViewStateMode="Enabled">

public partial class AdminPanel : System.Web.UI.Page
{
    storelocatorDataSetTableAdapters.storedbTableAdapter tastore = new storelocatorDataSetTableAdapters.storedbTableAdapter();
    storelocatorDataSetTableAdapters.View_1TableAdapter taview = new storelocatorDataSetTableAdapters.View_1TableAdapter();

    List<storelocatorDataSet.storedbRow> lststore = new List<storelocatorDataSet.storedbRow>();
    List<storelocatorDataSet.View_1Row> lstview = new List<storelocatorDataSet.View_1Row>();
    protected void Page_Load(object sender, EventArgs e)
    {
        lstview = taview.GetData().ToList();
        GridAllStore.DataSource = lstview; 
    }
}

{"Posts":
          [{"id":"1",
            "title":"Bibidh prothom khondo",
            "content":"sjih sdkljjdsf kdjsfjks",
            "author":"","last_update":"23 june 2013",
            "Comments":
                [{"id":"1",
                  "content":"sjih sdkljjdsf kdjsfjks",
                  "author":"","last_update":"23 june 2013"}]},
            {"id":"2",
             "title":"Bibidh prothom khondo",
             "content":"sjih sdkljjdsf kdjsfjks",
             "author":"",
             "last_update":"24 june 2013",
             "Comments":[{"id":"1","content":"sjih sdkljjdsf kdjsfjks","author":"","last_update":"23 june 2013"}]},{"id":"3","title":"Bibidh prothom khondo","content":"sjih sdkljjdsf kdjsfjks","author":"","last_update":"25 june 2013"}]}

我试图解析这个json.为此,我的代码是:

public class Attributes
    {
        [JsonProperty("id")]
        public string ID { get; set; }
        [JsonProperty("title")]
        public string TITLE { get; set; }
        [JsonProperty("content")]
        public string CONTENT { get; set; }
        [JsonProperty("author")]
        public string AUTHOR { get; set; }
        [JsonProperty("last_update")]
        public …

我有一个名为SharedData.java的getter setter类.当我要在我的代码上暗示它时,我得到空指针异常.这是SharedData类:

public class SharedData {
private static SharedData instance = null;

public SharedData() {
    // randomizeServers();
}

// data to be shared
private double src_latitude = -1;
private double src_longitude = -1;
private double end_latitude = -1;
private double end_longitude = -1;

//Getter-Setters
public static SharedData getInstance() {
    return instance;
}
public static void setInstance(SharedData instance) {
    SharedData.instance = instance;
}

public double getSrc_latitude() {
    return src_latitude;
}
public void setSrc_latitude(double src_latitude) {
    this.src_latitude = src_latitude;
}
public double …

1. 我有一个FragmentTabHost,托管在Fragment中.tabHost有4个标签.
2. 在第一个选项卡片段中,有两个嵌套片段.
3. 单击第一个嵌套片段中的视图后,会出现一个DialogFragment,它有几个按钮.

单击DialogFragment中的按钮后,我想切换到标签号3.我该怎么办？
