我刚刚将我的Windows Forms项目从.NET 3.0升级到.NET 3.5,并且升级将以下内容添加到我的app.config文件中:

<system.web>
  <membership defaultProvider="ClientAuthenticationMembershipProvider">
    <providers>
      <add name="ClientAuthenticationMembershipProvider" type="System.Web.ClientServices.Providers.ClientFormsAuthenticationMembershipProvider, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri=""/>
    </providers>
  </membership>
  <roleManager defaultProvider="ClientRoleProvider" enabled="true">
    <providers>
      <add name="ClientRoleProvider" type="System.Web.ClientServices.Providers.ClientRoleProvider, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri="" cacheTimeout="86400"/>
    </providers>
  </roleManager>
</system.web>

我认为system.web仅适用于Web项目.这看起来不对吗？

我有一个基于NAnt的脚本,我在连接到SQL Server 2008 Express的本地PC上运行,也在我的本地PC上运行,使用.sql文件删除和重新创建数据库 - 这很好用,这里没问题.

当我在另一台PC上重新创建相同的设置时出现问题,我在我的NAnt脚本中得到错误说:

System.InvalidOperationException: The 'SQLNCLI' provider is not registered on the local machine.
  at System.Data.OleDb.OleDbServicesWrapper.GetDataSource(OleDbConnectionString constr, DataSourceWrapper& datasrcWrapper)
  at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)

我在网上搜索过,发现在论坛中有人建议我需要安装Microsoft SQL Server Native Client,并从此URL获取.(不可否认,我只安装了Native Client部分) …

设置:Windows 7,IIS7.我正在开发一个通过本地IIS服务器查看的应用程序,而不是内置的调试Web服务器.所以我的应用网址是http://localhost/foo/bar.aspx.有没有 <customErrors>在我的web.config部分,我还没有在IIS中更改的设置.

如果发生任何错误,我总是会出现以下错误屏幕:

HTTP错误500.19 - 内部服务器错误 web.config文件中的部分不允许使用
绝对物理路径" C:\inetpub\custerr" system.webServer/httpErrors.请改用相对路径.

这是我的applicationhost.config内容:

<httpErrors errorMode="Custom" lockAttributes="allowAbsolutePathsWhenDelegated,defaultPath">
  <error statusCode="401" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="401.htm" />
  <error statusCode="403" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="403.htm" />
  <error statusCode="404" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="404.htm" />
  <error statusCode="405" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="405.htm" />
  <error statusCode="406" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="406.htm" />
  <error statusCode="412" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="412.htm" />
  <error statusCode="500" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="500.htm" />
  <error statusCode="501" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="501.htm" />
  <error statusCode="502" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="502.htm" />
</httpErrors>

如何摆脱此配置错误,以便查看详细错误？

我试图删除ie中的图像边框,但我得到了一些奇怪的行为.

这是我的代码:

img {border: none}

<img src="..." border="0" style="border: 0"/>

但它仍然无法正常工作,IE调试器显示我的图像border: medium.我的div比每张图片大10px.

我正在使用dataTables.js jQuery插件.

我的表的第一列是行计数器,所以我不希望它被用户排序.最后一列包含一些用户可以在一行上执行的操作链接.如何使这两列无法使用？

注意:我正在使用数据表的管道(服务器端进程)模式.

使用Google Apps脚本,有没有办法将Google Spreadsheet数组中的值写入范围而不进行循环？

我正在考虑以下内容,将每个名称放入单元格中 A1:A3

function demoWriteFromArray() {

   var employees=["Adam","Barb","Chris"];

   ssActive = SpreadsheetApp.getActiveSheet();

   rgMyRange = ssActive.getRange("A1:A3");

   rgMyRange.setValue(employees)
} 

上面的问题是执行后,A1:A3都包含={"Adam","Barb","Chris"} and display "Adam".

我试图让bootstrap div成为全身长.

这是我到目前为止所尝试的:http: //jsfiddle.net/bKsad/315/

html, body {
    min-height: 100%
}
.wrap {
    height: 100%
}
.sidebar {
    background-color:#eee;
    background-repeat: repeat;
    padding:0;
    min-height:100% !important;
    position:relative;
}
.sidebar .sidebar-content {
    height:100%;
    width:100%;
    padding: 5px;
    margin:0;
    position:relative;
}

随着右栏的长度增长,我希望侧栏也能做同样的事情.

我知道必须有一个更简单的方法来检查,但这就是我现在正在做的事情.

if (g.charAt(0) == 'a' || g.charAt(0) =='b' || g.charAt(0) =='c' ||
    g.charAt(0) == 'd' || g.charAt(0) =='e' || g.charAt(0) =='f' ||
    g.charAt(0) == 'g' || g.charAt(0) =='h')

我有两个不同的数据库模式中定义的相同表类型.当我尝试从一个模式调用SP到另一个模式作为参数传递类型时,我收到以下错误:

"操作数类型冲突myCustomType与myCustomType不兼容"

我有以下代码:

类型定义

CREATE TYPE myCustomType AS TABLE
(
  somevalue INT, 
  somevalue2 INT
);

存储过程定义

USE DB1
GO
CREATE PROC1( 
  @myVar myCustomType READONLY
)
AS
BEGIN
  EXEC db2.dbo.PROC2 @myVar
END

GO

USE DB2
GO
CREATE PROC2( 
  @myVar myCustomType READONLY
)
AS
BEGIN
  --do something with myVar  
END

执行

USE db1
GO
DECLARE @myVar myCustomType
INSERT into @myVar(1,2)
EXEC PROC1 @myVar

我该如何解决这个问题？

我有一个bootstrap 3崩溃的问题,在以编程方式打开面板后,可以在重新打开第一个面板时保持另一个面板打开.

我的HTML:
