  • Can't inherit from auto_str without problems

    - by fret
    What I want to do is this: #include <memory> class autostr : public std::auto_ptr<char> { public: autostr(char *a) : std::auto_ptr<char>(a) {} autostr(autostr &a) : std::auto_ptr<char>(a) {} // define a bunch of string utils here... }; autostr test(char a) { return autostr(new char(a)); } void main(int args, char **arg) { autostr asd = test('b'); return 0; } (I actually have a copy of the auto_ptr class that handles arrays as well, but the same error applies to the stl one) The compile error using GCC 4.3.0 is: main.cpp:152: error: no matching function for call to `autostr::autostr(autostr)' main.cpp:147: note: candidates are: autostr::autostr(autostr&) main.cpp:146: note: autostr::autostr(char*) I don't understand why it's not matching the autostr argument as a valid parameter to autostr(autostr&).

  • Connect Infopath form To Outlook - shows as xml

    - by gab
    In Sharepoint, i have a Forms Library. I would like to connect it to oulook. The problem is that once I do that, Outlook will display the forms in a .XML rendering...a bunch of text, not very user friendly. (I am using Sharepoint 2010, InfoPath 2010, Outlook 2010) Am I missing some kind of settings? How can I display the forms in Outlook in a rendered type of view. (I have tried this with Forms that open in Browser, as well as with Forms that open in Client application, with the same results for both.)

  • C++ Urban Myths

    - by Neil Butterworth
    I'm starting to write an article on what I'm calling "C++ Urban Myths" - that is, ideas and conceptions about C++ that are common but have no actual roots in reality. Some that I've come up with so far are: TR1 is part of standard C++ TR1 (technical Report #1) proposed a whole bunch of changes to C++. Unfortunately, it was never accepted. It is faster to use iterators to access a vector than operator[] Or vice versa. All tests I've carried out indicate the two are nearly identical in performance. The C++ Standard contains something called the STL It doesn't - neither "STL" nor "Standard Template Library" appear in the Standard. I'm wondering if the SO C++ community can come up with any better ones? Ideally, they should be expressible in a single sentence, and not involve any code. Edit: I guess I didn't make it clear enough that I was interested in myths believed by C++ developers, not misconceptions held by non-C++users. Oh well...

  • LINQ to Entity, joining on NOT IN tables

    - by SlackerCoder
    My brain seems to be mush right now! I am using LINQ to Entity, and I need to get some data from one table that does NOT exist in another table. For example: I need the groupID, groupname and groupnumber from TABLE A where they do not exist in TABLE B. The groupID will exist in TABLE B, along with other relevant information. The tables do not have any relationship. In SQL it would be quite simply (there is a more elegant and efficient solution, but I want to paint a picture of what I need) SELECT GroupID, GroupName, GroupNumber, FROM TableA WHERE GroupID NOT IN (SELECT GroupID FROM TableB) Is there an easy/elegant way to do this? Right now I have a bunch of queries hitting the db, then comparing, etc. It's pretty messy. Thanks.

  • Capturing stdout within the same process in Python

    - by danben
    I've got a python script that calls a bunch of functions, each of which writes output to stdout. Sometimes when I run it, I'd like to send the output in an e-mail (along with a generated file). I'd like to know how I can capture the output in memory so I can use the email module to build the e-mail. My ideas so far were: use a memory-mapped file (but it seems like I have to reserve space on disk for this, and I don't know how long the output will be) bypass all this and pipe the output to sendmail (but this may be difficult if I also want to attach the file)

  • iOS - Application logging test and production code

    - by Peter Warbo
    I am doing a bunch of logging when I'm testing my application which is useful for getting information about variable state and such. However I have read that you should use logging sparsely in production code (because it can potentially slow down your application). But my question is now: if my app is in production and people are using it, whenever a crash (god forbid) occurs, how will I be able to interpret the crash information if I have removed the logging statements? Then I suppose I will only have a stacktrace for me to interpret? Does this mean I should leave logging in production code only WHERE it's really essential for me to interpret what has happened? Also how will the logging statements relate to the crash reports? Will they be combined? I'm thinking of using Flurry as analytics and crash reports...

  • Creating custom Android project templates in Eclipse?

    - by Rich
    Every app I make starts out with a number of common base classes, interfaces, utility classes and a basic package structure that has been working for me. Is there a way for me to set up a project template in Eclipse that will give me all of the basic Android project stuff PLUS a bunch of custom packages, classes and interfaces? I guess I could just put all of this stuff into one or more libraries as opposed to creating a whole project template, so if you have a preferred approach or information/links/etc on how to do any of the above, please share (I'm relatively inexperienced with Eclipse, so the more detail the better). Thanks.

  • Search the public stream in Facebook

    - by camilo_u
    Hi, Is there any change i can search for anything in the Open Stream in Facebook? Let´s say that i want to look for "obama", this will return all of the obama mentions for a bunch of people in their streams, so far I haven't found anything like this, probably only looking in one user stream, but not the whole stuff. So, i haven't found a way to do this, but how come, sites like socialmention.com can do it? Do they query user by user streams? and how to do it without users permissions? What do you guys think? Thanks in advance! Camilo

  • Sending variables in URLs in PHP with echo

    - by alexpelan
    Hi all, I can't really find good guidelines through google searches of the proper way to escape variables in URLs. Basically I am printing out a bunch of results from a mysql query in a table and I want one of the entries in each row to be a link to that result's page. I think this is easy, that I'm just missing a apostrophe or backslash somewhere, but I can't figure it out. Here's the line that's causing the error: echo "<a href = \"movies.php/?movie_id='$row['movie_id']'\"> Who Owns It? </a> "; and this is the error I'm getting: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING If you could elaborate in your answers about general guidelines for working with echo and variables in urls, that would be great. Thanks.

  • GridView in UpdatePanel adds extra rows when sorting another grid

    - by chopps
    Hey Everyone, I'm a seeing some weird behavior that i have never seen before. I have two grid in separate UpdatePanels. I can page and sort each without any problems. Each grid is set for 10 per page. If the first grid (13 records) is paged to the second page and then i go down to the second grid (14 records) and page to the next page and the first grid adds a bunch of empty rows to the grid so it is full to show 10. There is no data in the rows...just empty rows. Each grid does this on paging and sorting. Ive stepped through the code and the the loading of the other grids never happens so it tells my AJAX is doing something to add the 'phantom' rows to the grid. Any ideas why or ways to debug this?

  • Managing the localization of Java properties files

    - by andri
    I have a Web application written in Java that is targeting several countries, all of which speak different languages (and more often than not, several languages -- that's Europe for you). We have a bunch of .properties files that hold the localized strings, and our current procedure is to e-mail the language-specific files to our partners for updating before doing major updates. However, this process is rather error-prone, as sometimes people forget to translate new strings and sometimes new strings don't get added to every language file, thus small mistakes get through very easily. Does anyone know of any existing software that could help us clear this mess? At a bare minimum, I'm thinking of something that would allow you to load a master file (for example, in English), a localized file and then would highlight the keys that were added to or removed from the master file.

  • Watermarking Flash Videos (server-side)

    - by Roberto Aloi
    Hi all, I have a bunch of flash videos that I need to watermark with user related information, to make illegal re-distribution of these files harder. I'm wondering how can this be done server-side. If done client-side, it will be quite easy for the user to intercept the videos before they are watermarked. Since the watermark should contain user-specific information I can't really watermark the videos before encoding them (unless I have an encoded video per user - not feasible). I'm expecting this to affect the streaming performances a lot, though. Any idea how this can be done (possibly in an efficient way)?

  • R: including model specifications in xtable(anova(...))

    - by HamiltonUlmer
    Hello R comrades: I have a bunch of loglinear models, which, for our purposes will just be glm() objects called mx, my, mz. I want to get a nicely-formatted xtable of the analysis of deviance, so naturally I would want to perform xtable(anova(mx, my, mz, test = "Chisq")). The vanilla output of xtable, however, doesn't include the model specifications. I'd like to include those for all the ANOVA tests I'm running, so if there is not a param I'm missing that does this I'll probably just have to hack up my own solution. But looking over the help page, there doesn't seem to be an easy way to include the model specifications. Any thoughts? Alternatives? If it helps this was done in 2.9.1 with xtable 1.5-5.

  • Rename files to increment filenumber using PowerShell?

    - by Frode Lillerud
    Hi, I've got a bunch of files named attachment.023940 attachment.024039 attachment.024041 attachment.024103 etc... I need to rename the files by incrementing the filenumber by a given number. (So that they match the right ID in a database) I guess I could write a C# application that uses RegEx to parse the filename, but I assume this is a task that could be accomplished in PowerShell as well? I've found several other threads on SO about using PowerShell to rename files, but none of them handled incrementing a filenumber. I'm on Win7, so PowerShell 2.0 is available.

  • Three20 Library Cannot find its own headers Xcode iPhone

    - by DieLaughing
    import "Three20/Three20.h" Fails. Go download it and build a sample app. If that works, then make a new app from the templates provided, then watch as it fails spectacularly to find the right HEADER_SEARCH_PATH. 1) I've gone to the info page for the TARGET and not the PROJECT (Well, I tried both) and tried a bunch of different paths for the HEADER_SEARCH_PATH field. 2) I've tried dragging and dropping the dependent files from the finder and COPYING or just referencing both fails. (RANT: WTF?! Really? I wish public code libraries saved me time ONCE in my life.)

  • How do I change the URL Alias for Security/login in SilverStripe to user/login

    - by pthurmond
    I am working on a new website being built in SilverStripe. Currently I am having a ton of trouble trying to get the system to let me change the URL alias (or create a second one) for the Security controller's login (and eventually logout) function. I have tried playing around with the routes.yml file and I tried creating the paths in my own UserController and loading directly from the Security controller with "return Security::login()". But that gives me errors about the use of the static functions. Unfortunately I don't come from a ton of object oriented experience and this is the first CMS I have used that actually uses a bunch of true object orientation. The current version of SilverStripe we are using is 3.0 (but we will be upgrading to 3.1.1 in a few days). Does anyone know much about the routing in SilverStripe?

  • INSERT INTO statement that copies rows and auto-increments non-identity key ID column

    - by AmoebaMan17
    Given a table that has three columns ID (Primary Key, not-autoincrementing) GroupID SomeValue I am trying to write a single SQL INSERT INTO statement that will make a copy of every row that has one GroupID into a new GroupID. Example beginning table: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b Goal after I run a simple INSERT INTO statement: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b 3 | 2 | a 4 | 2 | b I thought I could do something like: INSERT INTO MyTable ( [ID] ,[GroupID] ,[SomeValue] ) ( SELECT (SELECT MAX(ID) + 1 FROM MyTable) ,@NewGroupID ,[SomeValue] FROM MyTable WHERE ID = @OriginalGroupID ) This causes a PrimaryKey violation since it will end up reusing the same Max(ID)+1 value multiple times as it seems. Is my only recourse to a bunch of INSERT statements in a T-SQL WHILE statement that has an incrementing Counter value? I also don't have the option of turning the ID into an auto-incrementing Identity column since that would breaking code I don't have source for.

  • OpenSSH connection trouble

    - by gnostical
    Hi, I'm trying to use Putty 0.60 to log in to an OpenSSH 5.3 server. Connections with openssh from another Linux server are possible, but Putty fails. Putty's event log tells me "software caused connection abort" right after the DH key exchange, the server log doesn't report anything (set to INFO). I analyzed the traffic with Wireshark and got a whole bunch of "TCP retransmission" and "TCP DUP ACK" after said key exchange. Sometimes I was able to log in, but at some point (usually < 2 min.) the connection froze without any logged messages. Sadly, I didn't capture a trace. The server is my own (Funtoo with genkernel and gentoo-sources 2.6.34), so I may tweak it, but I'd still like to know what causes the error. Any suggestions? Thank you!

  • How useful are design patterns when it comes to web programming?

    - by Raja
    Background: My organization uses Microsoft .Net (3.5) with SQL Server 2005 as back end. With RAD being the norm and Agile being the widely used process. I have always found using design patterns difficult since it involves a bit more understanding and bit more training. Can you give me some examples where design patterns have solved real time problems in Web programming? What is the criteria for using any design pattern? What is the benefit reaped from it. I know it is a general question but this would help me a bunch.

  • new image makes http request even though cached?

    - by joshs
    I have a javascript slide show that creates the next slide dynamically and then moves it into view. Since the images are actually sprites, the src is transparent.png and the actual image is mapped via background:url(.. in css. Everytime (well, most of the time) the script creates a new Element, Firefox makes an http request for transparent.png. I have a far-future expires header, and Firefox is respecting all other files' expiries. Is there a way to avoid these unnecessary requests. Even though the server is returning 304 unmodified responses, it would be nice if Firefox would respect the expiries on dynamically created images. I suspect that if I injected a simple string instead of using new Element, this might solve the problem, but I use some methods on Prototypes extended Element object, so I would like to avoid a bunch of html strings in my js file. This is a nit-picky question, but I'm working on front-end optimization now, so I thought I would address it. Thanks.

  • Should I use a metaclass, class decorator, or override the __new__ method?

    - by 007brendan
    Here is my problem. I want the following class to have a bunch of property attributes. I could either write them all out like foo and bar, or based on some other examples I've seen, it looks like I could use a class decorator, a metaclass, or override the __new__ method to set the properties automagically. I'm just not sure what the "right" way to do it would be. class Test(object): def calculate_attr(self, attr): # do calculaty stuff return attr @property def foo(self): return self.calculate_attr('foo') @property def bar(self): return self.calculate_attr('bar')

  • Sync two SqlExpress using NHibernate

    - by Christian
    Hello, I am creating a simple project management system which uses NHibernate for object storage. The underlying database is SQL express (at least currently for development). The client runs on either the desktop or laptop. I know I could use web-services and store the DB only on the desktop, but this would force the desktop to be available all the time. I am currently thinking about duplicating the DB, having two instances with "different data". To clarify, we are not talking about a productive app here, its a prototype. One way to achieve this very simple would be the following process: Client: Check if desktop DB is available (through web service) Client: If yes, use desktop storage, no problem here Client: If not, use own DB as storage Client: Poll desktop regulary, as soon as it comes on, sync Client: Switch to desktop storage ... Desktop: Do not attempt any DB operation before checking for required sync Desktop: If sync needed, do it... My question is now, how would you sync? Assume 4 or 5 types of objects, all have GUID as identifiers. Would you always manually "lazy load" all objects of a certain type and feed them to the DB. Would you always drop the whole desktop DB in case the client DB may be newer and out of sync? Again, I want to stress out, I am not assuming any conflicts or stale data, I basically just want to "copy the whole DB from the client". Would you use NHibernate for this? Or would you separate the copy process? When I think about it, my questions comes down to this: Is there any function from NHibernate: SyncDBs_SourceWins_(SourceDB, TargetDB) Thanks for help, Chris
