I am trying to find two lots of expressions on a page and extract them. I currently can do one and extract the text from between certain tags with the following code:
Regex r = new Regex("<tag>([^<]*)</tag>");

Regex r = new Regex("<tag>([^<]*)</tag>" + "<ad ahs="e">([^<]*)<ad ahs=h>");
How can I put " in this regular expression

I'm having issues when trying to run my web app. I'm getting an expression expected error at runtime on the portion of my code that is designed to retain the screen position of multiple drag panels.
Code:
var target = $this).attr("id");
should return the id of the uniquely named panel so it can be used later in code to identify the _DragPanelExtender.BehaviorID
Code:
$find('<%=' + target + '_DragPanelExtender.BehaviorID%>').set_location(new Sys.UI.Point(parseInt(temp[0]), parseInt(temp[1])));
I haven't been able to verify if the dragPanel's id name is being used, it just errors out here. In the following code, I am attempting to preserve the position of multiple dragPanel's after postback?
Code:
function pageLoad() {
//get element id name of button clicked
var target = $(this).attr("id");
// call the savePanelPosition when the panel is moved
$find(target).add_move(savePanelPosition);
var elem = $get("<%=HiddenField1.ClientID%>");

I'm using linq to sql,everything seems to be working fine except one thing,I'm showing any mapped float fields from my db tables as "Double?" instead of "Double", and when binding to a datagrid, any of those "Double?"fields don't show.If I iterate through the items and spit out the property,the float value is indeed there and properly returned.
View 3 RepliesI write inline expression and binding expression in the server head section:
[Code]....
[Code]....
But both kinds of expression aren't parsed or executed except the ResovleUrl menthod. The html renders like this:
<head><link rel="stylesheet" type="text/css" href="<%= Request.ApplicationPath %>themes/style1.css" /><link rel="stylesheet" type="text/css" href="<%# Request.ApplicationPath %>themes/style2.css" />
<link rel="stylesheet" type="text/css" href="/themes/style3.css" />
<script type="text/javascript" src="/js/jwork.js"></script>
</head>
As I know, the inline expression in the attributes of server control can't be parsed but the binding expression should if we invoke the DataBind method. But the above case breaks the rule.
I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>

Since both are acceptable by HTML as well as languages like ASP.NET and PHP when using attributes or strings, why is it that some people use single quotes and double quotes interchangeably? It is my understanding that it is syntactically correct to use double quotes where possible, single when you need to embed a double quote for inline logic. Is there something I am missing? For examples: HTML
<a href='[URL]
PHP
<? echo 'Hello World!'; ?>
ASP.NET
<form id='myForm' runat='server'></form>

I need to send 4 double values to a webservice. Which is the best way to send. Array or Arraylist. I read some where that Arraylist has issues to serialize.I am using the following code on the client .aspx page to construct the arraylist.
Code:
ArrayList CapPlan = new ArrayList();
CapPlan .Add(Convert.ToDouble(TextBox1.Text));
CapPlan .Add(Convert.ToDouble(TextBox2.Text));
CapPlan .Add(Convert.ToDouble(TextBox3.Text));
CapPlan .Add(Convert.ToDouble(TextBox4.Text));
After this arraylist CapPlan is constructed, what would be the syntax to send this arraylist to a webmethod?
DataSet dataSetCapitalPlan = clientProxyobject.CapStock(CapPlan.ToArray(double));
And on the webservice side how can I receive this arraylist that was sent?
[WebMethod]
public DataSet CapStock(string As_of_Date, Array CapPlan)
{
}

Has anyone come across this before?
