• Check if a php script is still running

  - by Nirmal

  I have a script that listens to a jabber server and responds accordingly. Though it's not supposed to stop, last night it did. Now I want to run a cron job every minute to check if the script is running, and start it if not. The question is, how do I check if a particular script is still running? Some solutions have been posted here, but those are all for Linux, while I am looking for a Windows solution. Any ideas please? Thanks.

• FoxPro to C#: What best method between ODBC, OLE DB or another?

  - by Martin Labelle

  We need to read data from FoxPro 8 with C#. I'm gonna do some operations, and will push some of thoses data to an SQL Server database. We are not sure what's best method to read those data. I saw OLE DB and ODBC; what's best? REQUIRMENTS: The export program will run each night, but my company runs 24h a day. The DBF could sometimes be huge. We DON'T need to modify data. Our system, wich use FoxPro, is quite unstable: I need to find a way that ABSOLUTELY do not corrupt data, and, ideally, do not lock DBF files while reading. Speed is a minor requirement: it must be quick, but requirement #4 is most important.

• Connection problems - Celery/Django

  - by RadiantHex

  Hi folks, long night... can't get my second Celery/RabbitMQ setup run to work. step 1 sudo rabbitmq-server runs: ok! step 2 python manage.py celeryd -l info error: [2010-12-28 03:38:24,690: ERROR/MainProcess] CarrotListener: Connection Error: Socket closed. Trying again in 28 seconds... I have definitely: added rabbitmq user and vhost updated the Django setings.py Edit: I think it might have to with installing from a .deb instead of apt-get. After uninstalling the deb and installing the apt-get version I get this: invoke-rc.d: initscript rabbitmq-server, action "start" failed. dpkg: error processing rabbitmq-server (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: rabbitmq-server E: Sub-process /usr/bin/dpkg returned an error code (1) Any ideas on how I could debug this? :|

• NHybernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy

• Should I work with multiple recruiters for a job search or just pick one?

  - by BuckeyeSoftwareGuy

  So I posted my resume on dice and monster last night and today I've received 5 voicemails and about 6 emails from different recruiters wanting to talk to me. What's the best way to handle this situation. I want to reply to them all of course as I'm very interested in making an imminent job change. Is there some sort of rule of thumb here? It seems to me they would want to work with me exclusively if they could. I don't want to limit my options though..

• How do you make sure email you send programmatically is not automatically marked as spam?

  - by Leon Bambrick

  This is a tricky one - and I've always relied on techniques such as permission-based emails (i.e. only sending to people you have permission to send to) and not using blatantly spamish terminology. Of late, some of the emails I send out programmatically have started being shuffled into people's spam folder automatically - and I'm wondering what i can do about it. This is despite the fact that these particular emails are not ones that humans would mark as spam (specifically, they are emails that contain license keys that people have paid good money for, so I don't think they're going to consider them spam) I figure this is a big topic in which I am essentially an ignorant simpleton.

• Batch View updates

  - by Terry

  I want to load a bunch of view definitions into SQL Server 2005 & 2008. I am using IF/ELSE logic to dynamically building Create or Alter statements that I then EXEC. This works fine. However, unless I get the order of the statements correct, I get errors if a view is dependent on another view that would be created in a later statement. Is there a way to turn of the valiation of the SQL statements until after they have all been entered? It seems like the worst of both worlds. SQL Server does late binding and so it won't propogate changes to tables and views, but you can't create a view without all the pieces being in place.

• Get user-inputed file name from JFileChooser Save dialog box

  - by Anya

  This answer to this question may seem obvious, but I'm actually struggling with it quite a bit. I've searched through JFileChooser methods in the API, and I've looked at some of the questions already asked and answered here on stackoverflow. My question is this. In my program, I am to allow the user to type in a file name which I will then use to create a brand new file that I will write on. How do you get the text the user has entered in the textfield next to the label "Save As:" on the Save dialog box provided by JFileChooser? Is there a JFileChooser method that would allow me to get that user-inputed text? Or would I have to go through another class, or do something else to get that text? Thank you so much, to anyone who answers. It's very late for me now, and this program is due in a few hours (meaning I'll be having another sleepless night). Desperate may be too strong a word, but I'm something close enough.

• ETL mechanisms for MySQL to SQL Server over WAN

  - by Troy Hunt

  I’m looking for some feedback on mechanisms to batch data from MySQL Community Server 5.1.32 with an external host down to an internal SQL Server 05 Enterprise machine over VPN. The external box accumulates data throughout business hours (about 100Mb per day), which then needs to be transferred internationally across a WAN connection to an internal corporate environment before some BI work is performed. This should just be change-sets making their way down each night. I’m interested in thoughts on the ETL mechanisms people have successfully used in similar scenarios before. SSIS seems like a potential candidate; can anyone comment on the suitability for this scenario? Alternatively, other thoughts on how to do this in a cost-conscious way would be most appreciated. Thanks!

• Carrier Wave not completing upload to Rackspace Cloud Files

  - by Zack Fernandes

  Hello, I have been attempting to get file uploads to Rackspace Cloud Files online all night, and finally tried the Carrierwave Plugin. Although the plugin worked right away, when I tried viewing the file uploaded (an image) it was broken. Upon further testing, I found out that files would upload to Cloud Files, however were just a fraction of their original size. I can't seem to figure out what's worng, and any help would be greatly appreciated. My code is as follows. models\attachment.rb class Attachment < ActiveRecord::Base attr_accessible :title, :user_id, :file, :remote_file_url, :file_cache, :remove_file belongs_to :user mount_uploader :file, AttachmentUploader end uploaders\attachment_uploader.rb class AttachmentUploader < CarrierWave::Uploader::Base storage :cloud_files def store_dir "#{model.user_id}-#{model.id}" end end

• Stuck at "Hello World" with IntelliJ IDEA 9.0.1 for Scala

  - by Alex R

  I've been using Eclipse since 2.x and and IDEs in general for over 20 years (since Turbo Pascal and Turbo C in the late '80s!). (that preamble is supposed to imply, "I'm not an idiot" ... LOL :-] ) I'm trying to use the debugger in IntelliJ 9.0.1. I've resigned myself to an old standby: class hello { def main(a: Array[String]) = println("got args: " + a) } Alas, I'm unable to get even this simple Scala example to run. I'd like to eventually put a breakpoint in it, but for now just running it would be great. I have Java 1.6u20 and the Scala plug-in 0.3.473 (January 2010). The error below summarizes my experience: What possibly could I be doing wrong? Thanks

• ASP.NET CustomValidator trying to match to System.EventHandler?

  - by annakata

  I have markup so: <asp:TextBox runat="server" ID="Accountname" /> <asp:CustomValidator runat="server" ControlToValidate="Accountname" OnServerValidate="Accountname_CheckUnique" meta:resourcekey="ACCOUNTNAME_UNAVAILABLE" /> Codebehind so: protected void Accountname_CheckUnique(object source, ServerValidateEventArgs arguments) { arguments.IsValid = Foo(); } Which was working just fine, and then without changing anything on the page ASP now insists: No overload for 'Accountname_CheckUnique' matches delegate 'System.EventHandler' Well no, and nor should it according to MSDN. It's late and I'm tired, anybody know how to fix this or point out the glaring flaw in my comprehension?

• Geolocation Null in lat and long

  - by user1706989

  I have had issue today in one application where Geolocation is not working. Even on this page http://slaveryfootprint.org/survey/#where_do_you_live . When you enter a location , its showing null lattiude and longitude. Even though it search for autolocation, it can point the right location. and it happened all if a sudden today which was working fine since yestrday night and when I see in console it is returning null lat and long and null for city and I did not change the code at all. Did google map api changed something. or do I need to update jquery? http://maps.google.com/maps/api/js?v=3.4&sensor=false

• 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)

• Dangers of Windows API and Administrator accounts?

  - by Brett Powell

  I wrote a game server plugin last night that allowed me to create a user account and set it as administrator, which is a huge problem. Of course the simple fix is to create a basic user account with limited privileges for the game servers, so they would not have access to do things like this. I wanted to find out if there's anything else in the Windows API that would create such a huge vulnerability though? I guess I want to just make sure that when the client's game servers accounts are moved to limited access accounts, we won't have to worry about any of them using the windows API to sabotage the machines. There is already enough exploits in the game itself to worry about, without having to worry about client's taking over the machines with plugins lol. Some of the questions relative would be... Can you disable/enable Remote Desktop from c++? Can you get a list of AD user groups from c++? (not that a user belongs to, but a complete list)

• Is there any way to set or code breakpoints conditionally?

  - by froadie

  I've been wondering this for a while - is there a way to code/program breakpoints...? Conditionally? For example, can I specify something like - "when this variable becomes this value, break and open the debugger"? (Would be quite useful, especially in long loops when you want to debug loop execution of a late loop value.) I suppose this may be IDE-specific since debugging is implemented differently in different IDEs... I'd be interested to know how to do this in any IDE, but specifically in Eclipse and Visual Studio.

• What C#/SQL Server feature did someone show you that made you say Wow!

  - by Randy Minder

  It's late Friday afternoon, and my mind is checking out for the week. So I thought I'd ask a light-hearted, interesting, question. Yesterday a co-worker showed me how he managed to save quite a bit of code and improve code reuse through the use of an anonymous delegate and the use of the Action function. My first thought was, "Wow, I had no idea you could do that!". I'm curious what sort of things someone showed you, either in c# or SQL Server, that made you stop and think, "Wow!". Randy

• .Net opening and closing database connections

  - by Dan

  I designed the data access portion of our framework so that every time a business object needs to interact with the database it would have to open a connection, invoke the data access layer (to execute the query), and then close the connection. Then if it needed to run in a transaction it would open the connection, begin the transaction, invoke the data access layer (to execute the query) and then commit the transaction, close the transaction, and finally close the connection. I did it this way with the mindset of open late and close early... but what if I needed to call other BO's to submit data in a single transaction? Is there a better way to handle opening and closing connections as well as working with transactions? I'm a rookie in designing application architecture so I hope I'm not doing this wrongly... any help is appreciated.

• MySQL INTO OUTFILE overide existing file?

  - by Derek Organ

  I've written a big sql script that creates a CSV file. I want to call a cronjob every night to create a fresh CSV file and have it available on the website. Say for example I'm store my file in '/home/sites/example.com/www/files/backup.csv' and my SQL is SELECT * INTO OUTFILE '/home/sites/example.com/www/files/backup.csv' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM ( .... MySQL gives me an error when the file already exists File '/home/sites/example.com/www/files/backup.csv' already exists Is there a way to make MySQL overwrite the file? I could have PHP detect if the file exists and delete it before creating it again but it would be more succinct if I can do it directly in MySQL.

• How to copy a formatted cell in Excel to a table cell in Word using .NET?

  - by Harry Nath

  I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

• How to make a Webservice request follow a redirect?

  - by frappuccino

  My application neeeds to access a third part web service. Of late, they have introduced a load balancer, which redirects to the server. Because of this the webservice gets a 302 - Redirect error as response. In the SOAPUI, I was able to enable a property called "Follow Redirect", and because of this service followed the redirect and served by the server. Now is there a similar propety that can be turned on in the code, which would make the webservice follow the request? (The calling code is java and the webservice is in .net)

• Help with complex sql query

  - by eugeneK

  To make story short, i'm building self-learning banner management system. Users will be able to insert these banners to their site when banners will be shown based on sales/impressions ratio. I have 4 tables Banners bannerID int bannerImage varchar.... SmartBanners smartBannerID int smartBannerArrayID int bannerID int impressionsCount int visibility tinyint (percents) SmartBannerArrays smartBannerArrayID int userID int Statistics bannerID int saleAmountPerDay decimal... Each night i need to generate new "visibility" for each SmartBanner based on whole SmartBannerArray that same user has. So i need to get sum of impressions and sales for each bannerID in SmartBannerArray. All comes to my mind is to use double cursor, one will loop thought SmartBannerArrays get needed values for sum of impressions and sales and then inner loop which will access each SmartBanner and change it's "visibility" percentage based on (sales/impressions)/(sumOfSales/sumOfImpressions)*100 Hope you get the picture... Is there any other way to design better tables or not to use double cursor to avoid server overload ?

• unit test service layer - NUnit, NHibernate

  - by csetzkorn

  Hi, I would like to unit test a DEPENDENT service layer which allows me to perform CRUD operation without mocking using NUnit. I know this is probably bad practice but I want to give it a try anyway - even if the tests have to run over night. My data is persisted using NHibernate and I have implemented a little library that 'bootstraps' the database which I could use in a [Setup] method. I am just wondering if someone has done something similar and what the fastest method for bootstrapping the database is. I am using something like this: var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly("Bla"); new SchemaExport(cfg).Execute(false, true, false); to establish the db schema. After that I populate some lookup tables from some Excel tables. Any feedback would be very much appreciated. Thanks. Christian

• Jersey message body reader not found in maven-built JAR

  - by Olvagor

  My application uses a REST (JAX-RS Jersey) interface. When I run it in Eclipse, everything' s fine. The domain objects are annotated, I'm not using XML files for the REST mapping. Now I created a standalone JAR using the maven-assembly-plugin, which packs the application and all dependencies in a single, executable JAR file. This also seems to work. But when I start the application and request an object from the server, Jersey complains, that it can't find a message body reader: com.sun.jersey.api.client.ClientHandlerException: A message body reader for Java type, class de.rybu.atuin.core.entity.User, and MIME media type, application/json, was not found Any ideas why this happens? EDIT: After I slept a night over it, I noticed that it complains about JSON... but I'm using only XML for serialization. Strange.
