• C# parsing txt files IF name format is desired format

  - by jakesankey

  OK, I have txt files that I am parsing and saving into a sql db. The names are formatted like R306025COMP_272A4075_20090929_080159.txt However, there are a select few (out of thousands of files) with names that are formatted differently (particularly files that were generated as tests), example R306025COMP_SU2_TestBottom_20090915_101441.txt The reason this causes a problem for me is that I am using Split('_')[1,2,etc] to extract the R number, the 272A4075 portion, and the 20090929 (date) portion. When the application comes across the oddly named files, it fails because it is trying to parse 'TestBottom' as a date and inserts 'SU2' instead of the 272 number. Basically I want the app to recognize that if the file's name is not formatted like my first example, skip it. Any advice?

• htaccess redirect to subfolder and mask the url?

  - by KiwiCoder

  Hello all, Two things: Firstly - I have version 2 of a website located in a folder named v2, and I want to redirect any traffic that is NOT a child of the v2 folder, to www.example.com/v2 The old site located in the root was created in iWeb and has a LOT of subfolders and sub-subfolders. So: www.example.com/v2 = New site www.example.com/Page.html www.example.com/category/Page.html ww.example.com/category/subcategory/Page.html = All generic examples of what I need to redirect. Secondly, and I don't know if this is possible, I want to hide /v2/ in the URL, so that visitors will just see www.example.com/page even though they are actually on www.example.com/v2/page Links are hardcoded to the v2 folder, like so <a href="v2/contact.html" Any help is MOST appreciated. I've spent hours trying to figure this out, but I'm only just learning about htaccess and regular expressions, and am totally confused. Thanks so much!

• Load a file in a group objective-c Xcode

  - by okami

  I'd like to load a file from a specific Group in Xcode/Objective-c for example: I have TWO files named "SomeFile.txt" that are in two different folders (folders not groups yet) in the OS: SomeFolderOne |- SomeFile.txt SomeFolderTwo |- SomeFile.txt Inner Xcode I make two folders, and I put a REFERENCE to these two files: SomeGroupOne |- SomeFile.txt // this file is a reference to the SomeFile.txt from SomeFolderOne SomeGroupTwo |- SomeFile.txt // this file is a reference to the SomeFile.txt from SomeFolderTwo Now I want to read the txt content with: NSString *contents = [NSString stringWithContentsOfFile:@"SomeFile.tx" encoding:NSUTF8StringEncoding error:nil]; Ok it reads the 'SomeFile.txt' but sometimes the file read is from SomeGroupOne and sometimes the file is read from SomeGroupTwo. How to specify the group I want the file to be read?

• as3 swc component preview through code

  - by David

  I am developing an as3 swc-based component that populates its contents entirely through actionscript in the constructor (e.g. sprite.graphics.lineTo...). When I drag the component onto the stage, it is empty. If I export my movie, everything works perfectly, but I also need the live preview to work. I could get around this with a placeholder graphic, but I would much rather leave it purely as code. Is there any way to get around this? Thanks, David.

• Why is there an implicit conversion from Float/Double to BigDecimal, but not from String?

  - by soc

  Although the situation of conversion from Doubles to BigDecimals has improved a bit compared to Java scala> new java.math.BigDecimal(0.2) res0: java.math.BigDecimal = 0.20000000000000001110223024625156... scala> BigDecimal(0.2) res1: scala.math.BigDecimal = 0.2 and things like val numbers: List[BigDecimal] = List(1.2, 3.2, 0.7, 0.8, 1.1) work really well, wouldn't it be reasonable to have an implicit conversion like implicit def String2BigDecimal(s: String) = BigDecimal(s) available by default which can convert Strings to BigDecimals like this? val numbers: List[BigDecimal] = List("1.2", "3.2", "0.7", "0.8", "1.1") Or am I missing something and Scala resolved all "problems" of Java with using the BigDecimal constructor with a floating point value instead of a String, and BigDecimal(String) is basically not needed anymore in Scala?

• NHibernate custom connection string configuration

  - by user177883

  I have a c# library project, that i configured using nhibernate, and I like people to be able to import this project and use the project. This project has FrontController that does all the work. I have a connection string in hibernate config file and in app.config file of another project. it would be nice for anyone to be able to set the connection string into this library project and use it. such as through a method which will take the connectiong string as parameter. or when creating a new instance of FrontController to pass the connection string to constructor. or if you have a better idea. How to do this? I d like this class library to use the same database of the project that s imported. How to set hibernate connection string programatically? same idea for log4net.

• FakeTable with tSQLt remove triggers

  - by user1454695

  I have jsut started to use tSQLt and is about to test a trigger. I call the FakeTable procedure and do my test but the trigger is not executed. If don't use FakeTable the trigger is executed. That seems to be really bad and I canät find any info that there is any method to readded them. Then I thought the triggers are removed by FakeTable but I can recreate them after the call and did the following code in my test: DECLARE @createTrigger NVARCHAR(MAX); SELECT @createTrigger = OBJECT_DEFINITION(OBJECT_ID('MoveDataFromAToB')) EXEC tSQLt.FakeTable 'dbo.A'; EXEC(@createTrigger); I got the following error: "There is already an object named 'MoveDataFromAToB' in the database.{MoveDataFromAToB,14} (There was also a ROLLBACK ERROR -- The current transaction cannot be committed and cannot be rolled back to a savepoint. Roll back the entire transaction.{Private_RunTest,60})" Anyone that have any experience with tSQLt and know anyworkaround for this problem?

• Add a version number to the title of a LaTeX document.

  - by vgm64

  Hi. The title section of my LaTeX documents usually look like \title{Title} \author{Me} %\date{} %// Today's date will appear when this is commented out. \begin{document} \maketitle I'd really like to add another line in the title section for a version number: \title{Title} \author{Me} \version{v1.2} %\date{} %// Today's date will appear when this is commented out. \begin{document} \maketitle It doesn't necessarily have to be a command named version, but how can I get a version number to appear after the date (which is after the author)? I can manually set the version number.

• Is there an easy way to get a list of all successful captures from a regex pre-5.10?

  - by Chas. Owens

  I know the right way to do this if I have Perl 5.10 is to use named captures and values %+, but in Perl 5.8.9 and how can I get a list of successful captures? I have come up with two methods that are both just terrible: #you need to list each possible match my @captures = grep { defined } ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15, $16); and #ew, I turned on symbolic references { no strict 'refs'; my @captures = map { defined $+[$_] ? $$_ : () } 1 .. $#+; } There is a third option I have found involving (?{}), but it requires global variables (because the closure happens at compile time) and takes the regex from reasonably clear to ungodly mess. The only alternative I have found is to capture the whole match and then use another set of regexes to get the values I want (actually I build the first regex out of the other regexes because there is no good reason to duplicate the logic).

• Red5 OflaDemo Missing Java App

  - by Makram Saleh

  Hi All. I'm trying to run an application on Red5 server. It has the same basic functionality as the bundled demo named OFLADemo. So I installed Red5 and was able to see the welcome screen. I installed an app and tried the demo flash and all went well... But when I tried to install that particular application from /installer I got stuck with a dialog box with this message: installing oflaDemo-r3989-java6.war This may take a couple minutes, please wait. Waited for hours instead of minutes, but nothing happened. I was able to get that specific file from google code, but I don't know where to extract/place it. Any clues?

• EF4 generates invalid script

  - by Jaxidian

  When I right-click in a .EDMX file and click Generate Database From Model, the resulting script is obviously wrong because of the table names. What it generates is the following script. Note the table names in the DROP TABLE part versus the CREATE TABLE part. Why is this inconsistent? This is obviously not a reusable script. What I created was an Entity named "Address" and an Entity named "Company", etc (all singular). The EntitySet names are pluralized. The "Pluralize New Objects" boolean does not change this either. So what's the deal? For what it's worth, I originally generated the EDMX by pointing it to a database that had tables with non-pluralized names and now that I've made some changes, I want to go back the other way. I'd like to have the option to go back and forth as neither the db-first nor the model-first model is ideal in all scenarios, and I have the control to ensure that there will be no merging issues from multiple people going both ways at the same time. -- -------------------------------------------------- -- Dropping existing FOREIGN KEY constraints -- NOTE: if the constraint does not exist, an ignorable error will be reported. -- -------------------------------------------------- ALTER TABLE [Address] DROP CONSTRAINT [FK_Address_StateID-State_ID];

• mod_deflate Supported Encodings for Compression

  - by sparc

  It seems to me, that mod_deflate in Apache 2.2 will always return: Content-Encoding: gzip and never: Content-Encoding: deflate It was explained to me, that although there may be a deflate algorithm, mod_deflate is named after a file-format, in which the algorithm could be any of: gzip, bzip. pkzip Of those three, mod_deflate provides gzip. It seems as though gzip is the most popular and widely-supported algorithm in web browsers, but I know some web servers and proxies do return Content-Encoding: deflate. Aside from the confusion of the module's name, it true that mod_deflate will only return Content-Encoding: gzip? Thank you.

• How to translate legacy system (OLE) colors to (A)RGB?

  - by Paul Sasik

  I have a list of color values encoded as signed integers (OLE I think) in a legacy INI file that I need to translate into (A)RGB values with .NET. An INI example: [INI_Section] Color=-2147483633 Doing something like: Color.FromArgb(-2147483633) gives an alpha-blended version of a color that is not at all what I expect. I think that a value like -2147483633 is supposed to represent a system-defined, or named color like ButtonFace. Is there a .NET method for translating these legacy colors properly? Note that pInvoke to OlePro32.dll is not an option.

• Can anyone get this project to work? (EasyHook)

  - by Tom

  Hi, i'm trying to 'load' the following project into visual studio 2010 but im getting errors about dynamic link libraries not being found. I have manually referenced them but it doesnt like them. The project is: http://www.codeproject.com/KB/DLL/EasyHook64.aspx 2nd link down (EasyHook_2.5_Beta_Source_Code), and the project im wishing to load is EasyHook_2.5_Beta_Source_Code\Examples\ProcessMonitor The two dlls plus 1 executable i need are found in the first link (EasyHook 2.5 beta binaries) and named EasyHook.dll, EasyHook32.dll and EasyHook32svc.exe I've been trying to do this all night but i wonder whether its because im using VS2010 and .NET 4.0?? I'd be so appreciative if someone could have a go themselves just to see if its my setup or they get errors to. The error i get is: Unable to load DLL 'EasyHook32.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

• trouble configuring WCF to use session

  - by Michael

  I am having trouble in configuring WCF service to run in session mode. As a test I wrote this simple service : [ServiceContract] public interface IService1 { [OperationContract] string AddData(int value); } [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerSession)] internal class Service1 : IService1,IDisposable { private int acc; public Service1() { acc = 0; } public string AddData(int value) { acc += value; return string.Format("Accumulator value: {0}", acc); } #region IDisposable Members public void Dispose() { } #endregion } I am using Net.TCP binding with default configuration with reliable session flag enabled. As far as I understand , such service should run with no problems in session mode. But , the service runs as in per call mode - each time I call AddData , constructor gets called before executing AddData and Dispose() is called after the call. Any ideas why this might be happening?

• formula for best approximation for center of 2D rotation with small angles

  - by RocketSurgeon

  This is not a homework. I am asking to see if problem is classical (trivial) or non-trivial. It looks simple on a surface, and I hope it is truly a simple problem. Have N points (N = 2) with coordinates Xn, Yn on a surface of 2D solid body. Solid body has some small rotation (below Pi/180) combined with small shifts (below 1% of distance between any 2 points of N). Possibly some small deformation too (<<0.001%) Same N points have new coordinates named XXn, YYn Calculate with best approximation the location of center of rotation as point C with coordinates XXX, YYY. Thank you

• What is the underlying reason for not being able to put arrays of pointers in unsafe structs in C#?

  - by cons

  If one could put an array of pointers to child structs inside unsafe structs in C# like one could in C, constructing complex data structures without the overhead of having one object per node would be a lot easier and less of a time sink, as well as syntactically cleaner and much more readable. Is there a deep architectural reason why fixed arrays inside unsafe structs are only allowed to be composed of "value types" and not pointers? I assume only having explicitly named pointers inside structs must be a deliberate decision to weaken the language, but I can't find any documentation about why this is so, or the reasoning for not allowing pointer arrays inside structs, since I would assume the garbage collector shouldn't care what is going on in structs marked as unsafe. Digital Mars' D handles structs and pointers elegantly in comparison, and I'm missing not being able to rapidly develop succinct data structures; by making references abstract in C# a lot of power seems to have been removed from the language, even though pointers are still there at least in a marketing sense. Maybe I'm wrong to expect languages to become more powerful at representing complex data structures efficiently over time.

• BackgroundWorker not working with TeamCity NUnit runner

  - by Catalin DICU

  I'm using NUnit to test View Models in a WPF 3.5 application and I'm using the BackgroundWorker class to execute asynchronous commands.The unit test are running fine with the NUnit runner or ReSharper runner but fail on TeamCity 5.1 server. How is it implemented : I'm using a ViewModel property named IsBusy and set it to false on BackgroundWorker.RunWorkerCompleted event. In my test I'm using this method to wait for the BackgroundWorker to finish : protected void WaitForBackgroundOperation(ViewModel viewModel) { int count = 0; while (viewModel.IsBusy) { RunBackgroundWorker(); if (count++ >= 100) { throw new Exception("Background operation too long"); } Thread.Sleep(100); } } private static void RunBackgroundWorker() { Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate { })); System.Windows.Forms.Application.DoEvents(); } Well, sometimes it works and sometimes it hangs the build. I suppose it's the Application.DoEvents() but I don't know why...

• Serving files inside of directories with ruby and mongrel

  - by AdamB

  I made a simple web server in Ruby using the Mongrel gem. It works great for files in a single directory, but I run into some path issues when inside a directory. Lets say we have 2 files in a directory named "dir1", "index.html" and "style.css". If we visit http://host/dir1/index.html, the file is found, but style.css isn't because it's trying to load "style.css" from http://host/style.css instead of inside the directory. index.html is trying to load style.css as if its in the same directory as itself. <link href="style.css" rel="stylesheet" type="text/css" /> I can get the file if I enter the full path of style.css: /dir1/style.css but it doesn't seem to remember it's already inside a directory and that no path before a filename should serve from the current directory. This is the ruby code im using to serve out files. require 'rubygems' require 'mongrel' server = Mongrel::HttpServer.new("0.0.0.0", "3000") server.register("/", Mongrel::DirHandler.new(".")) server.run.join
