  - by kacalapy

  What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or... Now I am using C# and code like this in a big if with many ors: String.StartsWith("mailto:") String.StartsWith("ftp") It looks like a regex would be better for this. Or is there a C# way I am missing here?

• Eclipse does not format this if statement correctly

  - by Maroloccio

  This should be easy to answer: I have Eclipse set to wrap Java code over 80 chars to respect my margin. This code never wraps: if (expressionItem.type.isTypeCompatibleWith(containingNameLink.type) == false) { reportParsingError("expression type incompatible with containing " + "context."); } Question: how do I set my code formatter preferences so that the margin is respected?

• Counting HTML images with Python

  I need some feedback on how to count HTML images with Python 3.01 after extracting them, maybe my regular expression are used properly.

• use variable within a linq query

  - by jstawski

  take this linq into consideration: list.Where(sil => sil.XML.Element("ticket") != null && sil.XML.Element("ticket").Attribute("id").Value == smsRequestIn.TicketID) if the "ticket" element is not null it searches for it twice and hence is not very effective. Is there a way to use some sort of variables within the linq expression so I can reference the variable instead of doing a double search for the "ticket" element or is linq intelligent enough to not do a double search?

• How to exclude hidden row vaue from total value SSRS

  - by Annmarie

  I have an SSRS project and I want to exclude a row that I have hidden from the total. I have hidden the row based on an expression on the row visibility, where the row is hidden if: =IIF(IIF(ReportItems!CUST_CNT2.Value = 0, 0, ReportItems!Total_Contribution5.Value / IIF(ReportItems!CUST_CNT2.Value = 0, 1, ReportItems!CUST_CNT2.Value)) > 0, True, False) So basically the column totals for the report just total up all rows including this above row that I have hidden, and I need the total to exclude this row. Any ideas?

• How to test when a feature was added to Perl?

  - by Eric Strom

  Are there any services similar to codepad that will allow you to test Perl constructs on old versions of perl? Ideally, a system where you could enter an expression and it will tell you the oldest version of perl that it will work with. Of course it's possible to use CPANTS for this, but that seems like an abuse of the service (if only for making the BackPan bigger). And it could take several days/weeks to get decent test coverage on old versions.

• Detecting that a MemberExpression has a value

  - by cs

  How do I detect if a MemberExpression has a value that needs to be compiled/evaluated? I have two separate member expression outputs, the first which has a value, and the second which doesn't. What is the best way to differentiate between the two? exp **{value(Microsoft.Connect.Api.Client.Tests.SearchQueryUnitTests+<>c__DisplayClass6).handle}** [System.Linq.Expressions.MemberExpression]: **{value(Microsoft.Connect.Api.Client.Tests.SearchQueryUnitTests+<>c__DisplayClass6).handle}** NodeType: MemberAccess Type: {Name = "String" FullName = "System.String"} vs exp {x.CreatedBy} [System.Linq.Expressions.MemberExpression]: {x.CreatedBy} NodeType: MemberAccess Type: {Name = "String" FullName = "System.String"}

• Is it Acceptable to Abbreviate Lambda Parameters

  - by Russell Giddings

  I frequently see lambda expression parameters abbreviated to one character. For example... var stringList = new List<string>{ "one", "two", "three" }; stringList.Where(x => x.Length < 4); Is it acceptable to use x as the parameter name here or should a more descriptive name be used?

• Assign to a slice of a Python list from a lambda

  - by Bushman

  I know that there are certain "special" methods of various objects that represent operations that would normally be performed with operators (i.e. int.__add__ for +, object.__eq__ for ==, etc.), and that one of them is list.__setitem, which can assign a value to a list element. However, I need a function that can assign a list into a slice of another list. Basically, I'm looking for the expression equivalent of some_list[2:4] = [2, 3].

• What causes a lexical analysis error for eclipse in jsp EL validation?

  I've got some EL code inside of a JSP tag. The line starts as follows: <c:if test="${pageContext.request.serverName eq \'localhost\'}"> Eclipse throws up an error on this, saying: Unable to analyze EL expression due to lexical analysis error I'm unsure what this even means. Is this an eclipse bug? Am I mixing EL and the JSTL tags incorrectly?

• Rewrite URL, regex help...

  - by Tony

  Hello, I am using the following Rewrite URL: RewriteRule /([^/?.]+) /somedir/somefile.aspx\?Name=$1 [NC,L] which works great for my use, but I need to restrict it to only act on text that does not contain a filename... for example, if I use the url www.somedomain.com/SomeName it works fine, but it also fires if I use www.somedomain.com/TestPage.aspx So I am not sure if I need an additional Rewtire rule, or if the current one can be modified to disallow any text with an extension, for example. Any help with this regular expression would be greatly appreciated.

• Can a storyboard access the UserControl that it resides in?

  - by Jeremy

  I have a usercontrol, and I want a storyboard inside the user control to fade the user control out. Using Expression Blend, I can create the storyboard and cause it to fade the user control out, but when I run the silverlight application I get an error on FindControl stating that it can't find the control. I'm guessing the find control only searches the children of the parent, but does not look at the parent itself. Is there any way around this?

It would be nice to be able to set both ways, i.e. with databinding or in the derived control code behind, but neither work. With the data binding, it doesn't work. If I try in the code behind I get a null reference to 'header'. This is silverlight 4 (not sure if that makes a difference) Any suggestions on how to do with with both databinding and in code ?
