我想为我拥有的MTG卡创建一个数据库.设计是什么？我想存储有关每张卡的以下信息:

1. Name of card.
2. Set the card belongs to.
3. Condition of card.
4. Price it sold for.
5. Price I bought it for.

这里有一些关于MTG卡的信息:

1. Every card has a name. 
2. Every card belongs to a set.
3. A card may have a foil version of itself. 
4. Card name, set it belongs to, and whether it's foil or not makes it unique. 
5. A card may be in multiple sets.
6. A set has multiple cards. …

我有一个带有属性Day和Time的Schedule模型.时间是数据类型时间.

我有数据即

星期一/ 2014-04-26 15:00:00.000000

星期一/ 2014-04-25 16:30:00.000000

在我的控制器中我有 @schedule = Schedule.all(:order => 'Day, Time')

现在它是按日期排序,我如何按时间排序,无论日期如何？

如何使用VBA从MS Access更改Excel工作表中的单元格值？谢谢!

            ....
            Set objApp = CreateObject("Excel.Application")

            objApp.Visible = True
            Set wb = objApp.Workbooks.Open("fileHere.xls", True, False)

            'Below does not work (Title is in cell A1):
            wb.Sheets(1).Rows(1).Insert ("Replace Title Here")
            ....

我有这个触发器,我正在尝试调试.我需要知道它试图插入的值.以下Print @Item无效.

DECLARE @Item VARCHAR(MAX);



  INSERT INTO [BPRIL DATA ENTRY]
              ([COMPANY],
               [CUSTOMER],
               [ITEM #],
               [VENDOR],
               [SEASON],
               [BPRILP0CaseCost],
               [CustomerItem#])
  SELECT DISTINCT oh.company,
         oh.customer,
         @Item = ins.itemnumber,
         ins.vendor,
         oh.season,
         ins.VendorCost,
         oid.[CustomerSKU]
  FROM   [ORDER HEADER] AS oh
         LEFT JOIN [Order Item Detail] AS OID
           ON oh.[ORDER #] = OID.[ORDER #]
         LEFT JOIN [INSERTED] AS ins
           ON ins.[ITEM #] = OID.[ITEM #]
         LEFT JOIN [BPRIL DATA ENTRY] bp
           ON bp.[COMPANY] = oh.company
              AND bp.[CUSTOMER] = oh.customer
              AND bp.[ITEM #] = ins.itemnumber

rvm use ruby-1.9.3每次登录我的服务器时都必须输入.我该如何永久地这样做？

我有一个带有文本字段的表单:

<%= form_for @person do |f| %>
  <%= f.label :first_name, "First Name" %>:
  <%= f.text_field :first_name %>
  <%= f.submit %>
<% end %>

如何使用HTML5 Datalist元素自动填充文本字段？

如果单击复选框,如何防止页面重新加载？当我有数百个复选框时,这可能很麻烦.以下是我的代码:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
    Dim di As New IO.DirectoryInfo(ImagePath)
    Dim imageArray As IO.FileInfo() = di.GetFiles()
    Dim image As IO.FileInfo

    'list the names of all images in the specified directory

    For Each image In imageArray.OrderBy(Function(i) i.Name)
        CheckBoxList1.Items.Add(image.Name)
    Next
End If
End Sub

ASP.NET:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" RepeatLayout="table" RepeatColumns="4" RepeatDirection="vertical" AutoPostBack="True">
    </asp:CheckBoxList>

我相信我设置AutoPostBack = True,因为下面的代码:

Protected Sub btnDelete_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDelete.Click

    For count …

这在VB.NET中是可以的:If(hash.add(Numbers[index])) 但是如何在VB.NET中编写以下内容:If(!hash.add(Numbers[index]))

我不小心删除了我的Gemfile我rm Gemfile 可以恢复它还是重新创建一个？

我正在通过 |f|

f.print "ITEM", i

ITEM001 ITEM002 .... ITEM044 .... ITEM745

如何定义i,如果i为1,它将打印001始终确保有三位数？
