小编sak*_*kir的帖子

我有这样的课;

public  class MyStok
{
    public int STId { get; set; }
    public int SM { get; set; }
    public string CA { get; set; }
    public string Br { get; set; }
    public string BNo { get; set; }
    public decimal Vat { get; set; }
    public decimal Price { get; set; }
}

我像这样deserilala;

string sc=  e.ExtraParams["sc"].ToString();
MyStok myobj = JSON.Deserialize<MyStok>(sc);

我的输出似乎喜欢这个(字符串sc)在fiddler上

[
    {
        "STId": 2,
        "CA": "hbh",
        "Br": "jhnj",
        "SM": 20,
        "Vat": 10,
        "Price": 566,
        "BNo": "1545545" …

我正在尝试使用server_broker功能从sqlserver获取更改的值.

我的代码如下

 protected void Page_Load(object sender, EventArgs e)
{
    GetData2();

}
private void GetData2()
{
    List<Masa> lst = new List<Masa>();
    using (SqlConnection con = Baglan.Sql)
    {
        string sql = "SELECT [Id],[Ad],[Durum] FROM [dbo].[Masa]";
        using (SqlCommand cmd = new SqlCommand(sql, con))
        {
            con.Open();
            SqlDependency dependency = new SqlDependency(cmd);
            dependency.OnChange += new OnChangeEventHandler(dependency_OnDataChangedDelegate);

            using (IDataReader reader = cmd.ExecuteReader(CommandBehavior.CloseConnection))
            {
                while (reader.Read())
                {
                    Masa alt = new Masa
                    {
                        Ad = reader["Ad"].ToString(),
                        Id = reader["Id"].ToString(),
                        Durum = reader["Durum"].ToString()
                    };

                    lst.Add(alt);
                }

                gridMasa.GetStore().DataSource = …

我在这里有代码示例,我可以直接保存为PDF文件,但我想要做的是显示客户端的第一个pdf文件,并允许用户保存它.我该如何实现这一目标？

ReportDocument rpt = new ReportDocument();
rpt.Load(@"C:\CrystalReport2.rpt");

rpt.SetDataSource(datatablesource);

ExportOptions rptExportOption;
DiskFileDestinationOptions rptFileDestOption = new DiskFileDestinationOptions();
PdfRtfWordFormatOptions rptFormatOption = new PdfRtfWordFormatOptions();
string reportFileName = @"C:\SampleReport.pdf";
rptFileDestOption.DiskFileName = reportFileName;
rptExportOption = rpt.ExportOptions;
{
    rptExportOption.ExportDestinationType = ExportDestinationType.DiskFile;
    //if we want to generate the report as PDF, change the ExportFormatType as "ExportFormatType.PortableDocFormat"
    //if we want to generate the report as Excel, change the ExportFormatType as "ExportFormatType.Excel"
    rptExportOption.ExportFormatType = ExportFormatType.PortableDocFormat;
    rptExportOption.ExportDestinationOptions = rptFileDestOption;
    rptExportOption.ExportFormatOptions = rptFormatOption;
}

rpt.Export();

这是我的简单场景.我在ready()函数内部定义了一个变量,用于指定第一个值.

我也有外面的功能ready().我想要做的是在我的新函数中使用更改的变量.

这是我的JavaScript代码:

var myFunction = function() {
    // I wanna change Vp value here and wanna 
    // use this function with the new value        
    Vp = "new value";

    myFunction2 (); 
};

$(document).ready(function () {

    var Vp = "first value asign";
    $('#btnAddCustomer').click(myFunction);

    var myFunction2 = function() {
        // I will use Vp variable here with new value
    };
});

我有一个简单的应用程序,它实现了Activity.
我正在实施list-view onItemClickListener如下.但是,我需要在这个函数中创建一个Intent.

我怎样才能做到这一点？

listView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView <? > arg0, View arg1, int arg2,
        long arg3) {
        // TODO Auto-generated method stub
        Toast.makeText(getBaseContext(), "Click", Toast.LENGTH_LONG).show();
        //need to create intent here to load view

        Intent myintent = new Intent(this, MYclass.class);
        // but this gives me error
        myintent.putExtra("id", "test");
        startActivity(myintent);

    }

});

我有一些问题用这个表和代码创建查询,我知道"GROUP BY Branch.BranchName"导致获得多个记录,但是,如何避免这种情况并在单个查询中执行此操作.我想要得到的是一个包含BranchName的表 - total paidedvalue-- total notpayedvalue

SELECT
    (
        SELECT SUM (DeptDesciption.DeptValue)
        FROM dbo.SudentPayments
            INNER JOIN dbo.Student ON dbo.SudentPayments.StudentId = dbo.Student.StudentId
            INNER JOIN dbo.DeptDesciption ON SudentPayments.DeptDesciptionId = DeptDesciption.DeptDesciptionId
            INNER JOIN dbo.Branch on dbo.Branch.BranchId = Student.BranchId
        WHERE SudentPayments.IsDeptPayed = 0
        GROUP BY Branch.BranchName
    ) AS Payed,
    (
        SELECT SUM (DeptDesciption.DeptValue)
        FROM dbo.SudentPayments
            INNER JOIN dbo.Student ON dbo.SudentPayments.StudentId = dbo.Student.StudentId
            INNER JOIN dbo.DeptDesciption ON SudentPayments.DeptDesciptionId = DeptDesciption.DeptDesciptionId
            INNER JOIN dbo.Branch on dbo.Branch.BranchId = Student.StudentId
        WHERE SudentPayments.IsDeptPayed = 1
        GROUP BY Branch.BranchName …

我正在尝试添加分页存储过程的排序功能。

我该怎么做，到目前为止，我已经创建了这个。它可以正常工作，但是在传递@sort参数时不起作用。

ALTER PROCEDURE [dbo].[sp_Mk]
 @page INT,
 @size INT,
 @sort nvarchar(50) ,
 @totalrow INT  OUTPUT
AS
BEGIN
    DECLARE @offset INT
    DECLARE @newsize INT

    IF(@page=0)
    begin
       SET @offset = @page;
       SET @newsize = @size
    end
    ELSE 
    begin
        SET @offset = @page+1;
        SET @newsize = @size-1
    end
    -- SET NOCOUNT ON added to prevent extra result sets from
    SET NOCOUNT ON;
    WITH OrderedSet AS
    (
      SELECT *,
          ROW_NUMBER() OVER (ORDER BY @sort DESC) AS 'Index'
      FROM [dbo].[Mk]  
    )
   SELECT * …

我想这是一个简单的问题,但我需要帮助.

declare @Date date
SET   @Date =GETDATE()
print @date

宣言给了我结果: 2013-08-04

但我还需要几毫秒和几分钟.

我怎么能做到这一点？

如何将参数传递给sql server中的视图.我有一个stok包含stok信息,包括数量.我有一个表单,通过这个表单我添加了quatitiy到stok.我需要的是获取quatitiy的表单值并添加可用值的stok数量.为此我需要将pass参数传递给视图,该参数会自动将此值添加到stok中的当前值,谢谢大家的帮助
