• Powershell and some simple string manipulation

  - by Pat

  need some help with building a powershell script to help with some basic string manipulation. I know just enough powershell to get in trouble, but can't figure out the syntax or coding to make this work. I have a text file that looks like this - Here is your list of servers: server1 server2.domain.local server3 Total number of servers: 3 I need to take that text file and drop the first and last lines (Always first and last.) Then I need to take every other line and basically turn it into a CSV file. The final output should be a text file that looks like this - server1,server2.domain.local,server3 Any suggestions on where to start? Thanks!

  - by Mohammad

  Hi I'm using Closure Compiler to compress and join a few JavaScript files the syntax is something like this; $c = new PhpClosure(); $c->add("JavaScriptA.js") ->add("JavaScriptB.js") ->write(); How could I make it systematically add more files from an array lets say for each array element in $file = array('JavaScriptA.js','JavaScriptB.js','JavaScriptC.js',..) it would execute the following code $c = new PhpClosure(); $c->add("JavaScriptA.js") ->add("JavaScriptB.js") ->add("JavaScriptC.js") ->add ... ->write(); Thank you so much in advance!

• Unresolved symbol when inheriting interface

  - by LeopardSkinPillBoxHat

  It's late at night here and I'm going crazy trying to solve a linker error. If I have the following abstract interface: class IArpPacketBuilder { public: IArpPacketBuilder(const DslPortId& aPortId); virtual ~IArpPacketBuilder(); // Other abstract (pure virtual methods) here... }; and I instantiate it like this: class DummyArpPacketBuilder : public IArpPacketBuilder { public: DummyArpPacketBuilder(const DslPortId& aPortId) : IArpPacketBuilder(aPortId) {} ~DummyArpPacketBuilder() {} }; why am I getting the following error when linking? Unresolved symbol references: IArpPacketBuilder::IArpPacketBuilder(DslPortId const&): ppc603_vxworks/_arpPacketQueue.o IArpPacketBuilder::~IArpPacketBuilder(): ppc603_vxworks/_arpPacketQueue.o typeinfo for IArpPacketBuilder: ppc603_vxworks/_arpPacketQueue.o *** Error code 1 IArpPacketBuilder is an abstract interface, so as long as I define the constructors and destructions in the concrete (derived) interface, I should be fine, no? Well it appears not.

• Ant 1.8 include or import with nested resource collection

  - by Danny

  I'd like to have Ant automatically include or import resources matching a particular pattern, but I'm really struggling with the syntax. Here's what I've tried: <import> <fileset dir="${basedir}" includes="*-graph.xml" /> </import> However, I just get the error message import requires file attribute or at least one nested resource The documentation for import (and include) both say that you can use a nested resource collection, and the documentation for resource collections says <fileset> is a resource collection. I've Googled and can't find any useful examples at all. I'm using Ant 1.8.1 (verified with ant -version)

• Dynamically removing records when certain columns = 0; data cleansing

  - by cdburgess

  I have a simple card table: CREATE TABLE `users_individual_cards` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` char(36) NOT NULL, `individual_card_id` int(11) NOT NULL, `own` int(10) unsigned NOT NULL, `want` int(10) unsigned NOT NULL, `trade` int(10) unsigned NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `user_id` (`user_id`,`individual_card_id`), KEY `user_id_2` (`user_id`), KEY `individual_card_id` (`individual_card_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1; I have ajax to add and remove the records based on OWN, WANT, and TRADE. However, if the user removes all of the OWN, WANT, and TRADE cards, they go to zero but it will leave the record in the database. I would prefer to have the record removed. Is checking after each "update" to see if all the columns = 0 the only way to do this? Or can I set a conditional trigger with something like: //psuedo sql AFTER update IF (OWN = 0, WANT = 0, TRADE = 0) DELETE What is the best way to do this? Can you help with the syntax?

• 'Array of arrays' in matlab?

  - by waitinforatrain

  Hey, having a wee bit of trouble. Trying to assign a variable length 1d array to different values of an array, e.g. a(1) = [1, 0.13,0.52,0.3]; a(2) = [1, 0, .268]; However, I get the error: ??? In an assignment A(I) = B, the number of elements in B and I must be the same. Error in ==> lab2 at 15 a(1) = [1, 0.13,0.52,0.3]; I presume this means that it's expecting a scalar value instead of an array. Does anybody know how to assign the array to this value? I'd rather not define it directly as a 2d array as it is for are doing solutions to different problems in a loop Edit: Got it! a(1,1:4) = [1, 0.13,0.52,0.3]; a(2,1:3) = [1, 0, .268];

• Command-line input causes SyntaxError

  Good Day, I have a simple Python question that I'm having brain freeze on. This code snippet works. But when I substitue "258 494-3929" with phoneNumber, I get the following error below: # Compare phone number phone_pattern = '^\d{3} ?\d{3}-\d{4}$' # phoneNumber = str(input("Please enter a phone number: ")) if re.search(phone_pattern, "258 494-3929"): print "Pattern matches" else: print "Pattern doesn't match!" ####################################################### Pattern does not match Please enter a phone number: 258 494-3929 Traceback (most recent call last): File "pattern_match.py", line 16, in <module> phoneNumber = str(input("Please enter a phone number: ")) File "<string>", line 1 258 494-3929 ^ SyntaxError: invalid syntax C:\Users\Developer\Documents\PythonDemo> By the way, I did import re and tried using rstrip in case of the \n What else could I be missing?

• How to determine Jet database Engine Type programmatically

  - by MZB

  I have a program which needs to upgrade any Access (Jet) database it opens to JET Version4.x if it isn't already that version. (This enables use of SQL-92 syntax features) Upgrading is (relatively) easy. A call to the JRO.JetEngine object's CompactDatabase method (as described here) should do the trick, but before I do this I need to determine whether an upgrade is required. How do I determine the Jet OLEDB:Engine Type of an existing database? Can this be determined from an open OleDBConnection? Note: I'm talking about database versions, not Jet library versions. C# or .Net solution greatly appreciated.

• Auto-Complete Suggestions in Source Code Editor

  - by Jim

  Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!

• How to create a custom ADO Multi Demensional Catalog with no database

  - by Alan Clark

  Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.

• Does C++11 offer a better way to concatenate strings on the fly?

  - by Lohoris

  I've seen this answer, and I wonder (I hope) if C++11 has come up with a native better method to concatenate, and possibly format, strings. With "better" I mean actually really one-line, like in pretty much all higher level languages (bonus points if it supports something like python's "formatted string"%(tuple) syntax but I guess that's really hoping for too much). The ideal result should be something like: my_func("bla bla bla" << int(my_int) << "bla bla bla"); The only barely acceptable methods listed in that answer are the fastformat ones, but I wonder if C++11 managed to do better.

• web developer editor ubuntu

  - by madphp

  Hi, I know theres hundred of questions and answers out there, but cant find one to specifically answer this. I need a web editor that will let me choose a dark themed editor. I understand gvim is one, but im not totally ready to let go of my mouse. I would like something like sublime text editor for windows, but open to other suggestions. The less bloat the best. I dont need a full IDE like eclipse, but willing to compromise, as long as the themes can easily be added. I've tried bluefish, kompozer and not happy with them. Just need a basic text editor that will highlight php syntax on a dark background.

• DataView.RowFilter an ISO8601

  - by Ryan

  I have a DataTable (instance named: TimeTable) whose DefaultView (instance named: TimeTableView) I am trying to use to filter based on a date. Column clock_in contains an ISO8601 formatted string. I would like to select all the rows in this DataTable/DefaultView between 2009-10-08T08:22:02Z and 2009-10-08T20:22:02Z. What would I have to filter on this criteria? I tried: TimeTableView = TimeTable.DefaultView; TimeTableView.RowFilter = "clock_in >= #2009-10-08T08:22:02Z# and #2009-10-08T20:22:02Z#"; This is not working for me. Am I operating on the wrong object or is my filter syntax wrong?

• Stored Procedure for Multi-Table Insert Error: Cannot Insert the Value Null into Column

  - by SidC

  Good Evening All, I've created the following stored procedure: CREATE PROCEDURE AddQuote -- Add the parameters for the stored procedure here AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; Declare @CompanyName nvarchar(50), @Addr nvarchar(50), @City nvarchar(50), @State nvarchar(2), @Zip nvarchar(5), @NeedDate datetime, @PartNumber float, @Qty int -- Insert statements for procedure here Insert into dbo.Customers (CompanyName, Address, City, State, ZipCode) Values (@CompanyName, @Addr, @City, @State, @Zip) Insert into dbo.Orders (NeedbyDate) Values(@NeedDate) Insert into dbo.OrderDetail (fkPartNumber,Qty) Values (@PartNumber,@Qty) END GO When I execute AddQuote, I receive an error stating: Msg 515, Level 16, State 2, Procedure AddQuote, Line 31 Cannot insert the value NULL into column 'ID', table 'Diel_inventory.dbo.OrderDetail'; column does not allow nulls. INSERT fails. The statement has been terminated. I understand that I've set Qty field to not allow nulls and want to continue doing so. However, are there other syntax changes I should make to ensure that this sproc works correctly? Thanks, Sid

• Is there a practical alternative to struct inheritance? (C#)

  - by Tim Coulter

  I am writing code that will populate the Margin, Padding and BorderThickness properties of classes in the System.Windows.Documents namespace. Each of these properties accepts a value in the form of a System.Windows.Thickness, which is a struct. However, I wish to associate some additional data with each of these property assignments, which may subsequently be retrieved by my code. If Thickness were a class, I would inherit from it and define properties in the subclass to store my additional data items. But since it is a struct, inheritance is not possible. Is there any practical way to achieve this, while maintaining type-compatibility with the properties I am populating? Thanks for your ideas, Tim

• Limit the model data fields serialized by Web API based on the return type Interface

  - by Stevo3000

  We're updating our architecture to use a single object model for desktop, web and mobile that can be used in the MVVM pattern. I would like to be able to limit the data fields that are serialized through Web API by using interfaces on the controllers. This is required because the model objects for mobile are stored in HTML5 local storage so don't carry optional data while a thin desktop client would be able to store (and work with) more data. To achieve this a model will implement the different interfaces that define which data fields should be serialized and there will be a controller specific to the interface. The problem is that the Web API always serializes every field in the model even if it is not part of the interface being returned. How can we only serialize fields in the returned interface?

• Spring MVC 3.0: Avoiding explicit JAXBElement<> wrapper in method arg

  - by Keith Myers

  I have the following method and want to avoid having to explicitly show the JAXBElement< syntax. Is there some sort of annotation that would allow the method to appear to accept raw MessageResponse objects but in actuality work the same as shown below? I'm not sure how clear that was so I'll say this: I'm looking for some syntactic sugar :) @ServiceActivator public void handleMessageResponse(JAXBElement<MessageResponse> jaxbResponse) { MessageResponse response = jaxbResponse.getValue(); MessageStatus status = messageStatusDao.getByStoreIdAndMessageId(response.getStoreId(), response.getMessageId()); status.setStatusTimestamp(response.getDate()); status.setStatus("Complete"); }

• Perl Regex Output only characters that can be used as unix filename

"/" . $year ." - ". $album . "/" . $track ." - ". $artist ." - ". $title . ".mp3"; All I want is a regex to change $outname so that any non safe for filename characters get replaced by an underscore Thanks Jeff

• Can I see shader preprocessor output?

  - by GLaddict

  I am using #defines, which I pass runtime to my shader sources based on program state, to optimize my huge shaders to be less complex. I would like to write the optimized shader to a file so that next time I run my program, I do not have to pass the #defines again, but I can straight compile the optimized shaders during program startup because now I know what kind of shaders by program needs. Is there a way to get the result from shader preprocessor? I can of course store the #define values to a file and based on that compile the shaders during program startup but that would not be as elegant.

• For programming content, what simple-to-use-and-setup PHP based blog are the preferred ones?

  - by Johann Gerell

  I've since long wanted a place I can toss my programming related nuggets at. Every day I feel I solve something that I'll surely hit again in a not so distant future, but by then I most certainly will have forgotten about the previous solution I came up with. So I need to blog it down, quick and dirty, for my own documentation and memory's sake. Must be easy to set up and use. Must handle code syntax and highlighting gracefully for a number of languages, but mainly C# and C++. Must be PHP-based, because that's what my host supplies. I know and have used WordPress (not for code, though), but is it really what I want or need?

• Fastest method for SQL Server inserts, updates, selects

  - by Ian

  I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.
