var htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlText), styles);
document.Open();
BaseFont Vn_Helvetica = BaseFont.CreateFont(@"C:\Windows\Fonts\arial.ttf",
"Identity-H", BaseFont.EMBEDDED);
Font fontNormal = new Font(Vn_Helvetica, 12, Font.NORMAL);
foreach (var t in htmlarraylist)
{
document.Add((IElement)t);
//how set FontNormal if element is Paragraph?
}
document.Close();
有谁可以帮助我吗
using System.Text.RegularExpressions;
using System.DateTime;
DateTime returnedDate = DateTime.Now();
它给我错误:
A using namespace directive can only be applied to namespaces;
'System.DateTime' is a type not a namespace (line 1, pos 1)
我的错在哪里？
我有一个输入
<input type="text" style="width:200px" id="myInputTags" placeholder="add tag" />
<input type="button" id="btnId" />
在脚本中
jQuery("#myInputTags").textext({ plugins: 'tags' });
现在,当我在此输入中按Enter键时,标签已创建,但我想在点击我的按钮后添加此标签,并在按下"空格"后提出一些建议？
我有2个输入，其类型为number：
<input type="number">
http://jsfiddle.net/dkadr55g/1/
我想从右边隐藏箭头进行第一次输入，我找到了使用以下代码的解决方案：
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}
但如果使用此选项，则所有输入都不会创建箭头
http://jsfiddle.net/dkadr55g/2/
如何设置第一无箭头和第二无箭头？
我想计算PostgreSQL中一列的平均数
SELECT AVG(col_name)
From TableName
它给了我这个错误:
ERROR: function avg (character varying) does not exist
LINE 1: SELECT AVG(col_name)

HINT: No function matches the given name and argument types. You might need to add explicit type casts.
let options = [
{
"label": "Group 1",
"options": [

<Select
onChange={this.onChange}
closeMenuOnSelect={false}
isMulti

onChange仅针对组的子项触发，在文档中我找不到用于设置组标题可点击的属性或可以实现此目的的其他选项，有什么想法吗？
我也尝试为这样的团体增加价值

在Page_Load中
CurrentSearchUrl = Request.Url.AbsoluteUri;
CurrentSearchUrlParam = Request.Url+"&discount=1";
添加了param但是url不正确我当前的url是
http://localhost:1067/search/default.aspx?q=test
我想添加一个参数,应该是所需的结果
http://localhost:1067/search/default.aspx?q=test&discount=1

我设置了可以访问数据库
use DbName
GRANT SUBSCRIBE QUERY NOTIFICATIONS TO dbuser
use DbName
GRANT SELECT ON OBJECT::schema.tableName TO dbuser
Use DbName
GRANT RECEIVE ON QueryNotificationErrorsQueue TO dbuser
ALTER DATABASE DbName SET TRUSTWORTHY ON
use DbName
alter database DbName SET ENABLE_BROKER
但是当我启动SqlDependency时：
bool started = SqlDependency.Start(connectionString);
//started 是 false 然后我得到这个错误
System.Data.dll 中发生“System.InvalidOperationException”类型的异常，但未在用户代码中处理其他信息：在不提供选项值的情况下使用 SqlDependency 时，必须在执行添加的命令之前调用 SqlDependency.Start()到 SqlDependency 实例。
C#代码：
private static bool notificationEnabled = false;
private string connString= "Data Source=(local);Initial Catalog=MyDB;UID=dbuser; PWD=pass;";
public static void EnableNotifications()

// prevent for calling twice …我有一个表test有以下栏目:id,startDate,stopDate,startOvertime,stopOvertime.
startDate并且stopDate属于datetime类型startOvertime,stopOvertime属于类型time(7).
我想创建一个新列,其中包含日期部分stopDate和时间部分,startOvertime并将其复制到新创建的列中test-fill.
如果我使用公式(stopDate,startOvertime),则新的datetime列的值不正确.有什么建议？
