  • Boost.Program_Options not working with short options

    - by inajamaica
    I have the following options_description: po::options_description config("Configuration File or Command Line"); config.add_options() ("run-time,t", po::value(&runTime_)-default_value(1440.0), "set max simulation duration") ("starting-iteration,i", po::value(&startingIteration_)-default_value(1), "set starting simulation iteration") ("repetitions,r", po::value(&repetitions_)-default_value(100), "set number of iterations") ... ; As you can see the three shown have a long,short names employed. The long versions all work. However, none of the short ones do, and each time I try a -t 12345.0 or a -i 12345, etc., I get the following from Program_Options: std::logic_error: in option 'starting-iteration': invalid option value I'm using Boost 1.42 on Win32. Any thoughts on what might be going on here? Thanks!

  • jQuery Autocomplete: how to refresh list?

    - by cinematic
    I have a form with a variable number of autocomplete fields that use the same select list. These fields are added and removed as needed. Whenever a parameter on the page is changed, I (try to) update the list for all the fields by first calling unbind() then autocomplete() with a new parameter added to the url. $('input.foo').unbind().autocomplete(url?new_param=bar); The problem is that unbind() does not seem to be unbinding. When I type in the input field, it fires off the entire history of autocomplete events. I also tried flushCache to no avail. How do I clear out the old events? Thanks.

  • What happens if two COM classes each without a threading model are implemented in one in-proc COM se

    - by sharptooth
    Consider a situation. I have an in-proc COM server that contains two COM classes. Both classes are marked as "no threading model" in the registry - the "ThreadingModel" value is just absent. Both classes read/write the same set of global variable without any synchronization. As far as I know "no threading model" will enforce COM to disallow concurrent access to the same or different instances of the same class by different threads. Will COM prevent concurrent access to instances of the two abovementioned different classes? Do I need synchronization when accessing the global variables from two different COM classes in this situation?

  • How to deal with RGB to YUV conversion

    - by maximus
    The formula says: Y = 0.299 * R + 0.587 * G + 0.114 * B; U = -0.14713 * R - 0.28886 * G + 0.436 * B; V = 0.615 * R - 0.51499 * G - 0.10001 * B; What if, for example, the U variable becomes negative? U = -0.14713 * R - 0.28886 * G + 0.436 * B; Assume maximum values for R and G (ones) and B = 0 So, I am interested in implementing this convetion function in OpenCV, So, how to deal with negative values? Using float image? anyway please explain me, may be I don't understand something..

  • IWshShortcut Target Resolution in Windows 7

    - by Dan Walker
    I've got some code to read shortcuts using the Windows Script Host, but it appears to have a problem in Windows 7. When reading shortcuts, if there is an environment variable in the target path, it resolves to the wrong drive. For example, the shortcut to Notepad resolves to D:\Windows\system32\notepad.exe instead of C:\Windows\system32\notepad.exe. The problem is not with my computer's settings, because the shortcut works just fine, and when looking at the value for %SystemRoot%, it shows C:\Windows. Any ideas as to what could be the problem, or alternatively, what a different method of reading shortcuts would be? Thanks, Dan

  • Is this valid EJB-QL?

    - by Yishai
    I have the following construct in EJB-QL several EJB 2.1 finder methods: SELECT distinct OBJECT(rd) FROM RequestDetail rd, DetailResponse dr WHERE dr.updateReqResponseParentID is not null and dr.updateReqResponseParentID = ?1 and rd.requestDetailID = dr.requestDetailID and rd.deleted is null and dr.deleted is null IDEA's EJB-QL inspection flags the use of the two object FROM RequestDetail rd, DetailResponse dr with an inspection which says: Several ranged variable declarations are not supported, use collection member declarations instead (e.g. IN(o.lineItems)) The queries themselves function fine (as in return the expected results) on JBoss 4.2. Is IDEA all wet here, or is there a valid issue with the query? And what is the actual preferred alternative syntax for such a query?

  • JavaScript: Keeping track of eventListeners on DOM elements

    - by bobthabuilda
    What is the best way to keep track of eventListener functions on DOM elements? Should I add a property to the element which references the function like this: var elem = document.getElementsByTagName( 'p' )[0]; function clickFn(){}; elem.listeners = { click: [clickFn, function(){}] }; elem.addEventListener( 'click', function(e){ clickFn(e); }, false ); Or should I store it in my own variable in my code like below: var elem = document.getElementsByTagName( 'p' )[0]; function clickFn(){}; // Using window for the sake of brevity, otherwise I wouldn't =D // DOM elements and their listeners are referenced here in a paired array window.listeners = [elem, { click: [clickFn, function(){}] }]; elem.addEventListener( 'click', function(e){ clickFn(e); }, false ); Obviously the second method would be less obtrusive, but it seems it could get intensive iterating through all those possibilities. Which is the best way and why? Is there a better way?

  • Maven SVN checkout example

    - by c0mrade
    Concerning my previous question - http://stackoverflow.com/questions/2622191/is-there-a-svn-maven , I went trough usage page - http://maven.apache.org/scm/maven-scm-plugin/usage.html didn't found quite what I was looking for, here what I would like to do : Checkout list of projects which I specify for ex : http://mysvnurl/myprojectname where I could parametrize the project name Then lets say if there is 3-4 or n number of sub-projects(modules)(for which I can specify the names as well) that I want to checkout, and that I could specify branch(trunk) and revision. To simplify : Checkout certain sub-projects(modules) trunk of myprojectname Ex : http://mysvnurl/myprojectname/project1/trunk/* // get everything http://mysvnurl/myprojectname/project2/trunk/* // get everything How would I do that with maven, can someone with more expirience explain how to do this or point me to somewhere where I can read how to, I've googled nothing specific to my needs. Thank you

  • PHP mssql_query double quotes cannot be used

    - by Nilesh
    Hi all, In java-jdbc, I can easily run the following SQL (NOTE the double quotes around columns and table names) Select cus."customer_id" , cus."organisation_or_person" , cus."organisation_name" , cus."first_name" , cus."last_name" , cus."date_became_customer" , cus."other_customer_details" From "Contact_Management"."dbo"."Customers" cus But the same query in PHP errors out saying invalid syntax "Warning: mssql_query() [function.mssql-query]: message: Incorrect syntax near 'customer_id'. (severity 15) " But If remove all the double quotes, the query works fine and no errors. The query is ported from a java application so I would like to keep the double quotes and the SQL as it is. Any alternative solutions? Thank you Nilesh

  • Dot Net Nuke - Sub Domains

    - by Tristan
    Hi Guys, I've got a DNN portal set up for me and my brother, which works, and i'd like to make it so that sub domains point to our respective sub section of the sites. I.e. brothers.co.uk = brothers.co.uk/home.aspx me.brothers.co.uk = brothers.co.uk/me.aspx him.brothers.co.uk = brothers.co.uk/him.aspx I've got the sub sections set up in DNN, but can't figure out what to do with domain names to get it working. I'd like this to be all one site with the same login set, although if there's a better way to structure this, I'm open to ideas. Any thoughts? Regards Tristan

  • Return SQL Query as Array in Powershell

    - by Emo
    I have a SQL 2008 Ent server with the databases "DBOne", "DBTwo", "DBThree" on the server DEVSQLSRV. Here is my Powershell script: $DBNameList = (Invoke-SQLCmd -query "select Name from sysdatabases" -Server DEVSQLSRV) This produces my desired list of database names as: Name ----- DBOne DBTwo DBThree I has been my assumption that anything that is returned as a list is an Array in Powershell. However, when I then try this in Powershell: $DBNameList -contains 'DBTwo' It comes back has "False" instead of "True" which is leading me to believe that my list is not an actual array. Any idea what I'm missing here? Thanks so much! Emo

  • How to add an Interbase connection pool to glassfish?

    - by kgrad
    Hi, I am attempting to add an Interbase connection pool to GlassFish v3 to use EJB 3.1 in a project. The glassfish log appears to be connecting to my database properly, it spits out all my table names and indices. However, I get an error INFO: fetching database metadata SEVERE: could not complete schema update java.lang.NullPointerException at interbase.interclient.ResultSet.local_Close(Unknown Source) ... And when I ping the connection pool from within Glassfish I receive "Ping failed Exception - null". I have the following properties set with my connectionpool: resource type: javax.sql.DataSource Datasource Classname: interbase.interclient.DataSource portNumber: 3050 as well as my database info. I can't seem to find information elsewhere. This question is similar but did not receive an answer. thanks.

  • Declaring data types in SQLite

    - by dan04
    I'm familiar with how type affinity works in SQLite: You can declare column types as anything you want, and all that matters is whether the type name contains "INT", "CHAR", "FLOA", etc. But is there a commonly-used convention on what type names to use? For example, if you have an integer column, is it better to distinguish between TINYINT, SMALLINT, MEDIUMINT, and BIGINT, or just declare everything as INTEGER? So far, I've been using the following: INTEGER REAL CHAR(n) -- for strings with a known fixed with VARCHAR(n) -- for strings with a known maximum width TEXT -- for all other strings BLOB BOOLEAN DATE -- string in "YYYY-MM-DD" format TIME -- string in "HH:MM:SS" format TIMESTAMP -- string in "YYYY-MM-DD HH:MM:SS" format (Note that the last three are contrary to the type affinity.)

  • Multidimensional arrays in VB.NET 2010

    - by matt_t
    Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python). Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case? e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]] Apologies for the poor explanation but I cannot think of any better ways to explain.

  • How to get the same UITableViewCell layout as in the Address Book app?

    - by Romain
    Hi, I currently have a custom UITableViewCell which contains a few labels, and an image. The "main" label is used to display people's names. Currently, I'm styling it in bold text. What I'd like to do (to gain some space and readability), is to mimic the Address Book app cell style, that is: first name in light text, and family name in bold text. Is there a way to do this using the same UILabel? Or, should I use 2 different UILabels? How should I layout them, without knowing their sizes? Thanks in advance for your assistance!

  • Editing Mac OS X login items in Objective-C through AppleScript

    - by mon4goos
    In my Cocoa program, I want to examine what programs are registered to run at startup and modify that list as I feel appropriate. In order to be compatible with Tiger it seems like I need to work through AppleScript. I currently have the following code: NSDictionary* errorDict; NSAppleEventDescriptor* returnDescriptor = NULL; NSString *appleSource = @"tell application \"System Events\"\n\ get every login item\n\ end tell"; NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource: appleSource]; returnDescriptor = [appleScript executeAndReturnError: &errorDict]; If I run that command in AppleScript, I get back an array of login items. However, I can't figure out how to iterate through this array in Objective-C. More specifically, I want to examine the names and paths of the programs registered to run at startup. Any ideas?

  • how to bind to the results of a query in WPF

    - by randyc
    I have a query that hits a service and returns the results back to me as an indexed collection static void QueryActivities() { QueryClient qc = new QueryClient("BasicHttpBinding_IQuery"); QueryFilter filter = new QueryFilter(); filter.CallForService = false; var result = qc.GetFilteredActivityIndex(filter); result.Clone(); //inserted this just to test return in debug mode } WHen this is executed I get a return of 5 records ( actually five rows of data with multiple values per each row. id, type, date, address etc). I would like to bind this return to a gridview within a WPF application. Is there a way to refernce and bind to result variable or do I need to create a new collection and then add the return of result to the new collection? thank you

  • Why is thread local storage so slow?

    - by dsimcha
    I'm working on a custom mark-release style memory allocator for the D programming language that works by allocating from thread-local regions. It seems that the thread local storage bottleneck is causing a huge (~50%) slowdown in allocating memory from these regions compared to an otherwise identical single threaded version of the code, even after designing my code to have only one TLS lookup per allocation/deallocation. This is based on allocating/freeing memory a large number of times in a loop, and I'm trying to figure out if it's an artifact of my benchmarking method. My understanding is that thread local storage should basically just involve accessing something through an extra layer of indirection, similar to accessing a variable via a pointer. Is this incorrect? How much overhead does thread-local storage typically have? Note: Although I mention D, I'm also interested in general answers that aren't specific to D, since D's implementation of thread-local storage will likely improve if it is slower than the best implementations.

  • having a test debug app and a released debug app side by side

    - by Tristan
    Yo! When I download my app from the iStore, the latest test version installed to my phone gets over written. Does anyone know how to have two versions of the same app side by side? On a test project, I edited the build settings so that "realease" and "debug" have different product names. This seemed to solve my problem, however when I try this same trick on my actual project, the two overwrite each other again. Does anyone have a recommendation? I don't mind how it's done. Thanks!

  • SSH Chown problems

    - by Michael
    I have a webserver with multiple domain and user accounts setup. Recently I renamed one of the domain names and changed it's username correspondingly. However, this new user cannot access the data from the domain because it does not have the required permissions. How can I solve this problem? I've tried chown and I still cannot get access to the files. I have SSH root access and this is the only way I can actually move/touch the files but the webserver displays the file through another username which does not have access to the files. Thanks

  • Drupal: Sorting a view programmatically

    Hey there. I'm trying to take the results of a view - using the function views_get_view_result() - and sort the array in a way I couldn't do from within the Views interface. So far so good. I've got a $rows variable with all of the stuff I need. Now... How do I put it back? :) Before I needed this sort, I used views_embed_view(), but I can't do that anymore. Grateful for any help on this, feels like I'm so close to cracking it!
