• Clickonce program will not start when launched from shell_execute

  - by Brandon

  I have a very old program that I have no control over. It launches a filetype with its default application like this(I cannot modify this code): LET Err (SHELL_EXECUTE 'open' (FIX_MESG '"{1}"' File_name) '' '') ^^The above code works, so long as that filetype isn't associated with ClickOnce. The old program is 32 bit, the OS is Windows 7 64 bit. I can compile my clickonce program as anything, but none seem to work. (I've tried x84, x64 and anyCPU) How can I make a 32 bit program use shell execute to launch a ClickOnce program on a 64bit OS?

• What database works well with 200+GB of data?

  - by taw

  I've been using mysql (with innodb; on Amazon rds) because it's sort of universal default, but it's been ridiculously under-performing, and tweaking it only delays the inevitable. The data is mostly relatively short (<1kB of bytes each) blobs information about 100Ms of urls. There is (or should be, mysql cannot seem to handle it) very high amount of insert / update / retrieve but few complex queries - not that complex queries wouldn't be useful, but because mysql is so slow that it's far faster to get the data out, process it locally, and cache the results somewhere. I can keep tweaking mysql and throwing more hardware at it, but it seems increasingly futile. So what are the options? SQL/relational model/etc. optional - anything will do as long as it's fast, networked, and language-independent.

• Combine Hibernate class with @Bindable for SwingBuilder without Griffon?

  - by Misha Koshelev

  Dear All: I have implemented a back-end for my application in Groovy/Gradle, and am now trying to implement a GUI. I am using Hibernate for my data storage (with HSQLDB) per http://groovy.codehaus.org/Using+Hibernate+with+Groovy (with Jasypt for encryption) and it is working quite well. I was wondering if there are any good tips for using @Bindable with, e.g., an @Entity class such as @Entity class Book { @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long id @OneToMany(cascade=CascadeType.ALL) public Set<Author> authors public String title String toString() { "$title by ${authors.name.join(', ')}" } } or if I am: (i) asking for Griffon (ii) completely on the wrong track? Thank you! Misha

• Writing from an array to a file bash and new lines

  - by S1syphus

  I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?

• 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.

• Flowlayout panel and autosizing child controls doesn't work

  - by Pete

  I am trying to get a very simple autosizing layout on a winform (C# .NET). I've tried TableLayoutPanels and FlowLayoutPanels but nothing works. I have a usercontrol which is a container for other usercontrols which are created at runtime - I've called it StackPanel as I want it to list the child controls vertically. I've tried this using a FlowLayoutPanel, TableLayoutPanel and a Panel (with each control docked to the top). The child usercontrol consists of a label and then any number of radiobuttons (or any other standard control - it doesn't matter). When the child controls are created, the label text is set (if this is long it needs to wrap to a new line) and the radio buttons are added. There seems to be no combination of docking/autosizing or manual size setting using the Resize events that can get everything to show without clipping and still resize with the form. Thanks!

• How can I break from a method prematurely that's being called by NSTimer

  - by jammur

  Basically I'm writing a metronome app, but I'm using a sound file that, depending on the BPM, might not be finished playing when the "play" method is called again. For example, if the sound file is 0.5 seconds long, but the BPM is 200, the "play" method needs to be called every 0.3 seconds. I'm not overly familiar with NSTimer, but it appears that if it is supposed to fire before the previous invocation has completed, it doesn't, and just waits for the next time around. I could be completely wrong about that though. What I need to do is have the previous invocation end prematurely, and have the "play" method called again when the time is supposed to fire. Any help would be appreciated!

• Encrypt text using a number

  - by Adam Matan

  Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

• Close Flash Player from FlashDevelop IDE

  - by Josh Mohan

  Whenever I compile my project using FlashDevelop in 'Debug' the Flash Player window remains after I have clicked the 'Stop' button in Flash Develop. I have to then switch over to the flash player, click through any error messages and then close the player, which wastes a lot of time in the long run. Any way to make it so Flash Player closes when I click 'Stop' in the Flash Develop debug tools? EDIT: My setup is a fresh install of Windows 7, a new copy of Flash Develop 4 and Flash Player 10. Thanks! J

• Use ASP.NET Profile or not?

  - by DotnetDude

  I need to store a few attributes of an authenticated user (I am using Membership API) and I need to make a choice between using Profiles or adding a new table with UserId as the PK. It appears that using Profiles is quick and needs less work upfront. However, I see the following downsides: The profile values are squished into a single ntext column. At some point in the future, I will have SQL scripts that may update user's attributes. Querying a ntext column and trying to update a value sounds a little buggy to me. If I choose to add a new user specific property and would like to assign a default for all the existing users, would it be possible? My first impression has been that using profiles may cause maintainance headaches in the long run. Thoughts?

• XSLT good choice for web framework?

  - by Xepoch

  I've always thought of XML (and SGML before that) data as the devil's format. I'm of the old database and flat files school. Nonetheless, we are developing a commercially-available web product who's framework is based off of translating/transforming XML data in chains. As we're interviewing for positions as well talking to potential customers, they love the concept of what it will do but are weary of supporting XSLT long-term. One person even called it the proverbial "dead." Dead like COBOL, Unix, and C or dead like Apple Business BASIC? Anyway, I'm curious if building a web framework on XSLT is really not cutting edge enough (oddly) for companies. Are there inherent XSLT implementation problems that make this venture something worth reconsidering?

• What Are Basic Tools For A New Project?

  - by Morgan Cheng

  For a long time, I thought that to start a new project we only need 3 basic tools. 1) A Build System (e.g. Maven & CruiseControl) 2) A Version Control System (e.g. CVS & SVN & GIT) 3) A Bug Tracking System (e.g. Bugzilla) Yesterday, a senior guy told me that we need at least one thing more. That is KPI(Key Performance Index). Without KPI, it is impossible to measure whether the project is progressing well or not. KPI is kind of SOFT tool compared to Maven/SVN/Bugzilla. I believe since I missed SOFT tools, there must be some other kind of tools I missed. So, anybody get some ideas what other basic tools necessary for a new project?

• Table View rotate, but not properly (shape change)

  - by Pencrace

  Hello everyone, Here is the thing. I have a ViewController which contain a view in full window. And the program run in landscape mode. I want to put an UITableView over the full screen view but only on right half part of the screen. So I add a UITableView in my view controller, I used the Interface Builder in order to set the Table View in the upper half of the screen so It will be on the right part in LandscapeLeft mode. I searched for on a lot of forum how to rotate my Table View. And so it does... except, It get stuck on the upper half of the landscape mode, it should stick on the right half. I'm not a iPhone coder since long, so I'm a bit confused on how to solve this problem. Do you have any idea on how to resize or make the TableView rotate properly. Thanks,

• Ruby class instance variables and inheritance

  - by rlandster

  I have a Ruby class called LibraryItem. I want to associate with every instance of this class an array of attributes. This array is long and looks something like ['title', 'authors', 'location', ...] Note that these attributes are not really supposed to be methods, just a list of attributes that a LibraryItem has. Next, I want to make a subclass of LibraryItem called LibraryBook that has an array of attributes that includes all the attributes of LibraryItem but will also include many more. Eventually I will want several subclasses of LibraryItem each with their own version of the array @attributes but each adding on to LibraryItem's @attributes (e.g., LibraryBook, LibraryDVD, LibraryMap, etc.). So, here is my attempt: class LibraryItem < Object class << self; attr_accessor :attributes; end @attributes = ['title', 'authors', 'location',] end class LibraryBook < LibraryItem @attributes.push('ISBN', 'pages'] end This does not work. I get the error undefined method `push' for nil:NilClass

• How do I wait until a console application is idle?

  - by Anthony Mastrean

  I have a console application that starts up, hosts a bunch of services (long-running startup), and then waits for clients to call into it. I have integration tests that start this console application and make "client" calls. How do I wait for the console application to complete its startup before making the client calls? I want to avoid doing Thread.Sleep(int) because that's dependent on the startup time (which may change) and I waste time if the startup is faster. Process.WaitForInputIdle works only on applications with a UI (and I confirmed that it does throw an exception in this case). I'm open to awkward solutions like, have the console application write a temp file when it's ready.

• 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 can I have a serializable struct that wraps it's self as an int32 implicitly? in C#?

  - by firoso

  Long story short, I have a struct (see below) that contains exactly one field: private int value; I've also implemented implicit conversion operators: public static implicit operator int(Outlet val) { return val.value; } public static implicit operator Outlet(int val) { return new Outlet(val); } I've implemented all of the following : IComparable, IComparable<Cart>, IComparable<int>, IConvertible, IEquatable<Cart>, IEquatable<int>, IFormattable I'm at a point where I really have no clue why, but whenever I serialize this object, I get no value. For instance, with XmlSerialization: <Outlet /> Also, I'm not solely concerned about XmlSerialization, I'm concerned about ALL serialization (binary for instance) How can I ensure that this serializes properly? NOTE: I did this because mapping an int,int dictionary seemed rather poorly typed to me when explicit objects with validation behavior were desired.

• 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.

• Copy constructor with more than one parameter

  - by Ravi Gupta

  I am learning C++ and was reading copy constructor from the C++: The Complete Reference. The books says that It is permissible for a copy constructor to have additional parameters as long as they have default arguments defined for them. However, in all cases the first parameter must be a reference to the object doing the initializing. But I am confused that how we are going to pass those additional parameters? I am sure there should be some way which is not given in the book and which I am unable to figure out. Can anyone help me out? EDIT: Also is it possible to pass these extra parameters in all three cases i.e. ¦ When one object explicitly initializes another, such as in a declaration ¦ When a copy of an object is made to be passed to a function ¦ When a temporary object is generated (most commonly, as a return value)

• ListView OnItemClickListener Not Responding?

  - by GuyNoir

  I've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.

It strips those symbols is it? Sorry long day at work. Thanks guys!

• Maintaining session across relay domain?

  - by Steffen

  I'm building a payment page in asp.net, however the page where you order your items is run in HTTP (non-secure) on my domain. When redirecting the user to the payment site, I have to go through a different domain (my payment provider, from whom I borrow the SSL certificate), so my payment url ends up like https://www.paymentprovider.com/somescript.cgi/www.mydomain.com/mypaymentpage.aspx Now the problem is my session is lost, but I store the order in session, so I desperately needs it. Can I somehow send the SessionID in querystring, and restore the session from it - or do I need to stuff the entire order into querystring ? (Not too certain it'll fit though, it's rather long) Any help will be highly appreciated :-)

• Database query optimization

  - by hdx

  Ok my Giant friends once again I seek a little space in your shoulders :P Here is the issue, I have a python script that is fixing some database issues but it is taking way too long, the main update statement is this: cursor.execute("UPDATE jiveuser SET username = '%s' WHERE userid = %d" % (newName,userId)) That is getting called about 9500 times with different newName and userid pairs... Any suggestions on how to speed up the process? Maybe somehow a way where I can do all updates with just one query? Any help will be much appreciated! PS: Postgres is the db being used.
