  Hi, Case #1: I have ISPConfig3 running, sending email through telnet server.mydomain.com 25 are possible. Receiving email also possible. BUT!! problem occurs when I try to login to squirrel... I've been awaken for 2 days now and still couldn't figured out why logging in into squirrel always having an error: ERROR: Connection dropped by IMAP server. here is the /var/log/mail.log: Jun 3 00:23:27 server-01 imapd: Connection, ip=[::ffff:127.0.0.1] Jun 3 00:23:27 server-01 imapd: chdir /var/vmail/mydomain.com/info: Permission denied Jun 3 00:23:27 server-01 imapd: [email protected]: Permission denied I did chmod 777 & still doesn't work, only another message appeared Jun 3 00:24:28 server-01 imapd: Connection, ip=[::ffff:127.0.0.1] Jun 3 00:24:28 server-01 imapd: [email protected]: Account's mailbox directory is not owned by the correct uid or gid Try to do telnet to IMAP port telnet mydomain.com 143 Trying 63.105.102.48...

• What data structure to use / data persistence

  - by Dave

  I have an app where I need one table of information with the following fields: field 1 - int or char field 2 - string (max 10 char) field 3 - string (max 20 char) field 4 - float I need the program to filter on field 1 based upon a segmented control and select a field 2 from a picker. From this data I need to look up field 4 to use in a calculation. Total records will be about 200. I never see it go above 400 - 500. I am going to use a singleton which I am able to do, I just need help with the structure for this with data persistence. What type of data structure should I use for this and should I use NSNumber, NSString, etc. or old data types like float, Char, etc. I thought about a struct put into an array but there is probably a better way. This is new to me so any help or reference to examples would be great. I also thought about a plist or dictionary but it looks like it is just a lookup and a field which obviously won't work. Core data looked like overkill to me. Also, with any recommendation how should I get initial data into it? I want the user to be able to edit and add to the database. Sorry for the old terms, you can see what generation I am from... Thanks in advance!!!!

• Convert query with system objects from SQL 2000 to 2005/2008

  - by Dan

  I have some SQL I need to get working on SQL 2005/2008. The SQL is from SQL 2000 and uses some system objects to make it work. master.dbo.spt_provider_types master.dbo.syscharsets systypes syscolumns sysobjects I know SQL 2005 does no longer use system tables and I can get the same information from views, but I am looking for a solution that will work for both SQL 2000 and 2005/2008. Any ideas? select top 100 percent TABLE_CATALOG = db_name(), TABLE_SCHEMA = user_name(o.uid), TABLE_NAME = o.name, COLUMN_NAME = c.name, ORDINAL_POSITION = convert(int, ( select count(*) from syscolumns sc where sc.id = c.id AND sc.number = c.number AND sc.colid <= c.colid )), IS_COMPUTED = convert(bit, c.iscomputed) from syscolumns c left join syscomments m on c.cdefault = m.id and m.colid = 1, sysobjects o, master.dbo.spt_provider_types d, systypes t, master.dbo.syscharsets a_cha /* charset/1001, not sortorder.*/ where o.name = @table_name and permissions(o.id, c.name) <> 0 and (o.type in ('U','V','S') OR (o.type in ('TF', 'IF') and c.number = 0)) and o.id = c.id and t.xtype = d.ss_dtype and c.length = case when d.fixlen > 0 then d.fixlen else c.length end and c.xusertype = t.xusertype and a_cha.type = 1001 /* type is charset */ and a_cha.id = isnull(convert(tinyint, CollationPropertyFromID(c.collationid, 'sqlcharset')), convert(tinyint, ServerProperty('sqlcharset'))) -- make sure there's one and only one row selected for each column order by 2, 3, c.colorder ) tbl where IS_COMPUTED = 0

• Unit Testing Error - The unit test adapter failed to connect to the data source or to read the data

  - by michael.lukatchik

  I'm using VSTS 2K8 and I've set up a Unit Test Project. In it, I have a test class with a method that does a simple assertion. I'm using an Excel 2007 spreadsheet as my data source. My test method looks like this: [DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\MyTestData.xlsx;defaultdir=C:\\TestData;driverid=1046;maxbuffersize=2048;pagetimeout=5", "Sheet1", DataAccessMethod.Sequential)] [DeploymentItem("MyTestData.xlsx")] [TestMethod()] public void State_Value_Is_Set() { string expected = "MD"; string actual = TestContext.DataRow["State"] as string; Assert.AreEqual(expected, actual); } As indicated in the method decoration attributes, my Excel spreadsheet is on my local C:/ Drive. In it, the sheet where all of my data is located is named "Sheet1". I've copied the Excel spreadsheet into my project and I've set its Build Action = "Content" and I've set its Copy to Output Directory = "Copy if Newer". When trying to run this simple unit test, I receive the following error: The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library. Error details: ERROR [42S02] [Microsoft][ODBC Excel Driver] The Microsoft Office Access database engine could not find the object 'Sheet1'. Make sure the object exists and that you spell its name and the path name correctly. I've verified that the sheet name is spelled correctly (i.e. Sheet1) and I've verified that my data sources are set correctly. Web searches haven't turned up much at all. And I'm totally stumped. All help or input is appreciated!!!!

• Use of const double for intermediate results

  - by Arne

  Hi, I a writing a Simulation program and wondering if the use of const double is of any use when storing intermediate results. Consider this snippet: double DoSomeCalculation(const AcModel &model) { (...) const double V = model.GetVelocity(); const double m = model.GetMass(); const double cos_gamma = cos(model.GetFlightPathAngleRad()); (...) return m*V*cos_gamma*Chi_dot; } Note that the sample is there only to illustrate -- it might not make to much sense from the engineering side of things. The motivation of storing for example cos_gamma in a variable is that this cosine is used many time in other expressions covered by (...) and I feel that the code gets more readable when using cos_gamma rather than cos(model.GetFlightPathAngleRad()) in various expressions. Now the actual is question is this: since I expect the cosine to be the same througout the code section and I actually created the thing only as a placeholder and for convenience I tend to declare it const. Is there a etablished opinion on wether this is good or bad practive or whether it might bite me in the end? Does a compiler make any use of this additional information or am I actually hindering the compiler from performing useful optimizations? Arne

• Putting CAPTCHAs on their own page?

  - by mnemosyn

  We need to put a captcha image on our ASP.NET MVC 2 based website. We chose reCaptcha and built it in using the way described by Derik Whittaker. The idea there is baiscally to build some abstractions and all you need to do is decorate your Controller with a [ValidateCaptcha] attribute. This works all fine. However, we have a lot of form-widgets in different pages and I don't want to have the captcha floating around everywhere. So I'd like to implement it the way StackOverflow does: Submit a Form -> Challenge Captcha -> Submit Captcha -> Perform Action on original form data. Now, how do I redirect the user to the captcha page while keeping the originally submitted information? I thought of some very ugly hacks (hidden fields w/ base64 encoded form data, etc.) but I think I'm missing something obvious. On the other hand, this sounds as if I wanted to do something in a stateful manner, and I shouldn't?

• What makes merging in DVCS easy?

  - by afriza

  I read at Joel on Software: With distributed version control, the distributed part is actually not the most interesting part. The interesting part is that these systems think in terms of changes, not in terms of versions. and at HgInit: When we have to merge, Subversion tries to look at both revisions—my modified code, and your modified code—and it tries to guess how to smash them together in one big unholy mess. It usually fails, producing pages and pages of “merge conflicts” that aren’t really conflicts, simply places where Subversion failed to figure out what we did. By contrast, while we were working separately in Mercurial, Mercurial was busy keeping a series of changesets. And so, when we want to merge our code together, Mercurial actually has a whole lot more information: it knows what each of us changed and can reapply those changes, rather than just looking at the final product and trying to guess how to put it together. By looking at the SVN's repository folder, I have the impression that Subversion is maintaining each revisions as changeset. And from what I know, Hg is using both changeset and snapshot while Git is purely using snapshot to store the data. If my assumption is correct, then there must be other ways that make merging in DVCS easy. What are those?

• Binding data to the custom DataGridView

  - by Jatin Chaturvedi

  All, I have a customized DataGridView where I have implemented extra functionality and bounded datasource in the same custom DataGridView (Using C# and .NET). Now, I could able to use it properly by placing it on a panel control. I have added label as button on panel control to display data from datasource on to datagrid and create a binding source. Another Label which act as a button is used to update data from grid to databse. Issue: I pressed show label to display data in a dsatagridview. Modified the grid cell value and immediately pressed update label which is on same panel control. I observed that, the cursor is still in the grid cell when I press Save button. While saving, the cell value is null even though I have entered something in the presentation layer. My expected behaviour is to get the modified value while saving. Special Case: After typing something in the grid cell, if I click on somewhere else like the row below where I entered something, before I click on Save button, it is working fine. (Here, mainly I tried to remove the focus from the currently modified cell) Is there any way to bind sources before I click on save button? Please suggest me. Please feel free to ask me if you need any information. I have also seen same kind of problem on this forum, but unfortunately the author got the answer and didnt post it back. here is that URL: http://social.msdn.microsoft.com/Forums/en/winformsdesigner/thread/54dcc87a-adc2-4965-b306-9aa9e79c2946 Please help me.

• Sorting Arrays by More the One Value, and Prioritizing the Sort based on Column data.

  - by Mark Tomlin

  I'm looking for a way to sort an array (we call this a row), with an array of values (that I'll call columns). Each row has columns that must be sorted based on the priority of: timetime, lapcount & timestamp. Each column cotains this information: split1, split2, split3, laptime, lapcount, timestamp. laptime if in hundredths of a second. (1:23.45 or 1 Minute, 23 Seconds & 45 Hundredths is 8345.) Lapcount is a simple unsigned tiny int, or unsigned char. timestamp is unix epoch. The lowest laptime should be at the get a better standing in this sort. Should two peoples laptimes equal, then timestamp will be used to give the better standing in this sort. Should two peoples timestamp equal, then the person with less of a lapcount get's the better standing in this sort. By better standing, I mean closer to the top of the array, closer to the index of zero where it a numerical array. I think the array sorting functions built into php can do this with a callback, I was wondering what the best approch was for a weighted sort like this would be.

• Possible to recover mysql root pass with sudo server access?

  - by jonathonmorgan

  I've inherited development for a website on vps hosting, and have login info for a user with sudo privileges, but don't have the password for the mysql root user. After digging around a little, it looks like the only way to fix this is to stop mysql (something like this: http://waoewaoe.wordpress.com/2010/02/03/recover-reset-mysql-root-password/). But because the website it's serving is currently in production, I'm hoping you guys can enlighten me to any potential consequences (or let me know if there's typically a file where the password would be accessible). a) during the time mysql is stopped, information in the database won't be accessible, right -- even by other users? b) will resetting the root password have any impact on other users after mysql has restarted? Will their username/passwords still be valid? The current application is using an account with limited privileges to read/write to the database, and while 5min downtime in the middle of the night would probably go unnoticed, half a day while I tie up loose ends/figure out what I screwed up will land in me hot water. Thanks in advance for your help!

• Should we migrate from svn to Team Foundation Server 2010?

  - by Florian

  We are with 6 developer and currently use Visual Studio 2008 Professional with SVN and Visual SVN. As soon as vs2010 is released we will upgrade from vs2008 pro to vs2010 premium. However if Team Foundation Server has a proper source control included in vs2010 premium, then it does make sense to use it. We like SVN, but like tight integration of tools even better. On the internet information on SVN versus TFS 2010 seems to be scarce. Hence my question here. EDIT: This video looks very compelling. Is this marketing talk or real? Thank you all for your replies! I absolutely appreciate this. A little more background info. This is our current stack; vs2008 pro, Visual SVN, SVN, Jetbrain Teamcity. My main problem is that we use a lot of tools from different vendors which more or less integrate. Sometime more, mostly less. At least it takes a lot of time to set it up correctly. We currently do not use branches, but we want to. Therefore we have to set up SVN from scratch (we looked into it carefully). So let me rephrase my question: Should we set up SVN or start using TFS?

• Programatic re-evalutation of MVVM command's "can execute" state

  - by dzs

  Hello! I'm writing a WPF application using the MVVM pattern, based on the following article: WPF Apps With The Model-View-ViewModel Design Pattern I have two buttons on my View with the buttons' "Command" property bound (with data binding) to a given instance of the RelayCommand class (see "Figure 3 The RelayCommand Class" from the article above). The RelayCommand class has support for checking whether the given command can be executed. WPF automatically disables buttons whose command cannot be executed. Each of my commands (in the ViewModel class) start a background operation, and the command cannot be executed again until the background operation is finished. The RelayCommand instances have information whether the background operation is still working or it is finished. My problem is the following: after pressing the any of the buttons, the buttons automaticaly go disabled (which is OK) because the background operation started and the command cannot be executed until it is finished, but after the operation had finished, the buttons don't go enabled automatically because their command's "can be executed" predicate is not automatically reevaluated. The reevaluation can be manually triggered by having the application loose and regain focus (by pressing ALT+TAB). After doing this trick, the buttons get enabled once again. How can I programatically reevaluate the buttons' command's "can execute" state?

• Jquery get each div's sub child divs and grab info into an array

  - by McNabbToSkins

  I have a some html that looks like this <div id="main"> <div id="sub_main_1" class="sub_main"> <input type="text" class="sub_name_first" /><br /> <input type="text" class="sub_name_second" /><br /> </div> <div id="sub_main_2" class="sub_main"> <input type="text" class="sub_name_first" /><br /> <input type="text" class="sub_name_second" /><br /> </div> </div> I would like to pull out each sub_main divs information into an array in javascript. So far I have this as my jquery code $('#main').find('.sub_main').each( function() { alert('hi'); }); The alert is just a test that it should show "hi" twice. But this is not working. I am also not clear on how I can store the two inputs in a javascript array. Any help would be great! Thanks,

• Problem with JMX query of Coherence node MBeans visible in JConsole

  - by Quinn Taylor

  I'm using JMX to build a custom tool for monitoring remote Coherence clusters at work. I'm able to connect just fine and query MBeans directly, and I've acquired nearly all the information I need. However, I've run into a snag when trying to query MBeans for specific caches within a cluster, which is where I can find stats about total number of gets/puts, average time for each, etc. The MBeans I'm trying to access programatically are visible when I connect to the remote process using JConsole, and have names like this: Coherence:type=Cache,service=SequenceQueue,name=SEQ%GENERATOR,nodeId=1,tier=back It would make it more flexible if I can dynamically grab all type=Cache MBeans for a particular node ID without specifying all the caches. I'm trying to query them like this: QueryExp specifiedNodeId = Query.eq(Query.attr("nodeId"), Query.value(nodeId)); QueryExp typeIsCache = Query.eq(Query.attr("type"), Query.value("Cache")); QueryExp cacheNodes = Query.and(specifiedNodeId, typeIsCache); ObjectName coherence = new ObjectName("Coherence:*"); Set<ObjectName> cacheMBeans = mBeanServer.queryMBeans(coherence, cacheNodes); However, regardless of whether I use queryMBeans() or queryNames(), the query returns a Set containing... ...0 objects if I pass the arguments shown above ...0 objects if I pass null for the first argument ...all MBeans in the Coherence:* domain (112) if I pass null for the second argument ...every single MBean (128) if I pass null for both arguments The first two results are the unexpected ones, and suggest a problem in the QueryExp I'm passing, but I can't figure out what the problem is. I even tried just passing typeIsCache or specifiedNodeId for the second parameter (with either coherence or null as the first parameter) and I always get 0 results. I'm pretty green with JMX — any insight on what the problem is? (FYI, the monitoring tool will be run on Java 5, so things like JMX 2.0 won't help me at this point.)

• C# Inheritence: Choosing what repository based on type of inherited class

  - by Oskar Kjellin

  I have been making a program that downloads information about movies from the internet. I have a base class Title, which represents all titles. Movie, Serie and Episode are inherited from that class. To save them to the database I have 2 services, MovieService and SerieService. They in turn call repositories, but that is not important here. I have a method Save(Title title) which I am not very happy with. I check for what type the title is and then call the correct service. I would like to perhaps write like this: ITitleService service = title.GetService(); title.GetSavedBy(service); So I have an abstract method on Title that returns an ITitleSaver, which will return the correct service for the instance. My question is how should I implement ITitleSaver? If I make it accept Title I will have to cast it to the correct type before calling the correct overload. Which will lead to having to deal with casting once again. What is the best approach to dealing with this? I would like to have the saving logic in the corresponding class.

• How do I process a nested list?

  - by ddbeck

  Suppose I have a bulleted list like this: * list item 1 * list item 2 (a parent) ** list item 3 (a child of list item 2) ** list item 4 (a child of list item 2 as well) *** list item 5 (a child of list item 4 and a grand-child of list item 2) * list item 6 I'd like to parse that into a nested list or some other data structure which makes the parent-child relationship between elements explicit (rather than depending on their contents and relative position). For example, here's a list of tuples containing an item and a list of its children (and so forth): [('list item 1',), ('list item 2', [('list item 3',), [('list item 4', [('list item 5'),]] ('list item 6',)] I've attempted to do this with plain Python and some experimentation with Pyparsing, but I'm not making progress. I'm left with two major questions: What's the strategy I need to employ to make this work? I know recursion is part of the solution, but I'm having a hard time making the connection between this and, say, a Fibonacci sequence. I'm certain I'm not the first person to have done this, but I don't know the terminology of the problem to make fruitful searches for more information on this topic. What problems are related to this so that I can learn more about solving these kinds of problems in general?

• Need some advice on Core Data modeling strategy

  - by Andy

  I'm working on an iPhone app and need a little advice on modeling the Core Data schema. My idea is a utility that allows the user to speed-dial their contacts using user-created rules based on the time of day. In other words, I would tell the app that my wife is commuting from 6am to 7am, at work from 7am to 4pm, commuting from 4pm to 5pm, and home from 5pm to 6am, Monday through Friday. Then, when I tap her name in my app, it would select the number to dial based on the current day and time. I have the user interface nearly complete (thanks in no small part to help I've received here), but now I've got some questions regarding the persistent store. The user can select start- and stop-times in 5-minute increments. This means there are 2,016 possible "time slots" in week (7 days * 24 hours * 12 5-minute intervals per hour). I see a few options for setting this up. Option #1: One array of time slots, with 2,016 entries. Each entry would be a dictionary containing a contact identifier and an associated phone number to dial. I think this means I'd need a "Contact" entity to store the contact information, and a "TimeSlot" entity for each of the 2,016 possible time slots. Option #2: Each Contact has its own array of time slots, each with 2,016 entries. Each array entry would simply be a string indicating which phone number to dial. Option #3: Each Contact has a dictionary of time slots. An entry would only be added to the dictionary for time slots with an active rule. If a search for, say, time slot 1,299 (Friday 12:15pm) didn't find a key @"1299" in the dictionary, then a default number would be dialed instead. I'm not sure any of these is the "right" way or the "best" way. I'm not even sure I need to use Core Data to manage it; maybe just saving arrays would be simpler. Any input you can offer would be appreciated.

• Is ther any tool to extract keywords from a English Text or Article In Java?

  - by user555581

  Dear Experts, I am trying to identify the type of the web site(In English) by machine. I try to download the homepage of the web iste, download html page, parsing and get the content of the web page. Such as here are some context from CNN.com. I try to get the keywords of the web page, mapping with my database. If the keywords include like news, breaking news. The web site will go to the news web sites. If there exist some words like healthy, medical, it will be the medical web site.

• "error creating files compilation failed" when publishing for iOS on Flash CS5.5

  - by user1662660

  I'm currently developing an app using Flash CS5.5 for iOS. All of my .ipa files have been created and tested with no problems so far. Until now. I'm using Windows. It only started today and happens to every file I try to publish. I get the error "error creating files. compilation failed..." That is the only piece of information I am given about the error. All of my certificates and provisioning profiles are legit and still valid. Has anyone had any experience with this before? Since posting the question I have found a resolution that I will post for anyone who encounters the same problem. In this case I was unable to publish my .ipa file as I was opening the document (and Flash) from the start menu in Windows 7. To fix this instance of the issue I simply opened Flash first and then opened my document and I was able to publish.

• Extending EF4 SQL Generation

  - by Basiclife

  Hi, We're using EF4 in a fairly large system and occasionally run into problems due to EF4 being unable to convert certain expressions into SQL. At present, we either need to do some fancy footwork (DB/Code) or just accept the performance hit and allow the query to be executed in-memory. Needless to say neither of these is ideal and the hacks we've sometimes had to use reduce readability / maintainability. What we would ideally like is a way to extend the SQL generation capabilities of the EF4 SQL provider. Obviously there are some things like .Net method calls which will always have to be client-side but some functionality like date comparisons (eg Group by weeks in Linq to Entities ) should be do-able. I've Googled but perhaps I'm using the wrong terminology as all I get is information about the new features of EF4 SQL Generation. For such a flexible and extensible framework, I'd be surprised if this isn't possible. In my head, I'm imagining inheriting from the [SQL 2008] provider and extending it to handle additional expressions / similar in the expression tree it's given to convert to SQL. Any help/pointers appreciated. We're using VS2010 Ultimate, .Net 4 (non-client profile) and EF4. The app is in ASP.Net and is running in a 64-Bit environment in case it makes a difference.

• Using Active Directory to authenticate users in a WWW facing website

  - by Basiclife

  Hi, I'm looking at starting a new web app which needs to be secure (if for no other reason than that we'll need PCI accreditation at some point). From previous experience working with PCI (on a domain), the preferred method is to use integrated windows authentication which is then passed all the way through the app to the database. This allows for better auditing as well as object-level permissions (ie an end user can't read the credit card table). There are advantages in that even if someone compromises the webserver, they won't be able to glean any additional information from the database. Also, the webserver isn't storing any database credentials (beyond perhaps a simple anonymous user with very few permissions) So, now I'm looking at the new web app which will be on the public internet. One suggestion is to have a Active Directory server and create windows accounts on the AD for each user of the site. These users will then be placed into the appropriate NT groups to decide which DB permissions they should have (and which pages they can access). ASP already provides the AD membership provider and role provider so this should be fairly simple to implement. There are a number of questions around this - Scalability, reliability, etc... and I was wondering if there is anyone out there with experience of this approach or, even better, some good reasons why to do it / not to do it. Any input appreciated Regards Basiclife

• SQL 2008: Using separate tables for each datatype to return single row

  - by Thomas C

  Hi all I thought I'd be flexible this time around and let the users decide what contact information the wish to store in their database. In theory it would look as a single row containing, for instance; name, adress, zipcode, Category X, Listitems A. Example FieldType table defining the datatypes available to a user: FieldTypeID, FieldTypeName, TableName 1,"Integer","tblContactInt" 2,"String50","tblContactStr50" ... A user the define his fields in the FieldDefinition table: FieldDefinitionID, FieldTypeID, FieldDefinitionName 11,2,"Name" 12,2,"Adress" 13,1,"Age" Finally we store the actual contact data in separate tables depending on its datatype. Master table, only contains the ContactID tblContact: ContactID 21 22 tblContactStr50: ContactStr50ID,ContactID,FieldDefinitionID,ContactStr50Value 31,21,11,"Person A" 32,21,12,"Adress of person A" 33,22,11,"Person B" tblContactInt: ContactIntID,ContactID,FieldDefinitionID,ContactIntValue 41,22,13,27 Question: Is it possible to return the content of these tables in two rows like this: ContactID,Name,Adress,Age 21,"Person A","Adress of person A",NULL 22,"Person B",NULL,27 I have looked into using the COALESCE and Temp tables, wondering if this is at all possible. Even if it is: maybe I'm only adding complexity whilst sacrificing performance for benefit in datastorage and user definition option. What do you think? Best Regards /Thomas C
