  • Why is CoRegisterClassObject creating two extra threads?

    - by Stijn Sanders
    I'm trying to fix a problem that only recently happens on a number of machine's on a VPN. They each run a client application I wrote that exposes a COM automation object. For some strange reason I haven't been able to discover yet, one thread in the application takes up all of the available CPU time, slowing other operation on the machine. In observing the application's strange behaviour, I've noticed it's the third thread started, and if I debug on my machine I notice the first call to CoRegisterClassObject created two extra threads. If the second of these two threads is the one that gets into an infinite loop, I'm not at all shure how to fix this. Where could I check next about what's wrong? Could it have started by one of the recent patches rolled out by Microsoft this last 'patch tuesday'? I had a go with ProcessExplorer to extract a stack trace of the thread: ntoskrnl.exe!ExReleaseResourceLite+0x1a3 ntoskrnl.exe!PsGetContextThread+0x329 WLDAP32.dll!Ordinal325+0x1231 WLDAP32.dll!Ordinal325+0x129e WLDAP32.dll!Ordinal325+0x1178 ntdll.dll!LdrInitializeThunk+0x24 ntdll.dll!LdrShutdownThread+0xe9 kernel32.dll!ExitThread+0x3e kernel32.dll!FreeLibraryAndExitThread+0x1e ole32.dll!StringFromGUID2+0x65d kernel32.dll!GetModuleFileNameA+0x1ba

  • Perl, creating a hash of hashes.

    - by Mike
    Based on my current understanding of hashes in Perl, I would expect this code to print "hello world." It instead prints nothing. %a=(); %b=(); $b{str} = "hello"; $a{1}=%b; $b=(); $b{str} = "world"; $a{2}=%b; print "$a{1}{str} $a{2}{str}"; I assume that a hash is just like an array, so why can't I make a hash contain another?

  • Creating Ada record with one field

    - by ada hater
    I've define a type: type Foo is record bar : Positive; end record; I want to create a function that returns an instance of the record: function get_foo return Foo is return (1); end get_foo; But Ada won't let me, saying "positional aggregate cannot have one argument". Stupidly trying, I've added another dumb field to the record, and then return (1, DOESNT_MATTER); works! How do I tell Ada that's not a positional aggregate, but an attempt to create a record?

  • Creating a db driven primary navigation in django?

    - by Fedor
    I find that it's pretty common most people hardcode the navigation into their templates, but I'm dealing with a pretty dynamic news site which might be better off if the primary nav was db driven. So I was thinking of having a Navigation model where each row would be a link. link_id INT primary key link_name varchar(255) url varchar(255) order INT active boolean If anyone's done something similar in the past, would you say this sort of schema is good enough? I also wanted for there to be an optional dropdown in the admin near the url field so that a user could choose a Category model's slug since category links would be common, but I'm not quite sure how that would be possible.

  • How do I map repeating columns in NHibernate without creating duplicate properties

    - by Ian Oakes
    Given a database that has numerous repeating columns used for auditing and versioning, what is the best way to model it using NHibernate, without having to repeat each of the columns in each of the classes in the domain model? Every table in the database repeats these same nine columns, the names and types are identical and I don't want to replicate it in the domain model. I have read the docs and I saw the section on inheritance mapping but I couldn't see how to make it work in this scenario. This seems like a common scenario because nearly every database I've work on has had the four common audit columns (CreatedBy, CreateDate, UpdatedBy, UpdateDate) in nearly every table. This database is no different except that it introduces another five columns which are common to every table.

  • Approach for parsing file and creating dynamic data structure for use by another program

    - by user275633
    All, Background: I have a customer who has some build scripts for their datacenter based on python that I've inherited. I did not work on the original design so I'm sort of limited to some degree on what I can and can't change. That said, my customer has a properties file that they use in their datacenter. Some of the values are used to build their servers and unfortunately they have other applications that also use these values so I cannot change them to make it easier for me. What I want to do is make the scripts more dynamic to distribute more hosts so that I don't have to keep updating the scripts in the future and can just add more hosts to the property file. Unfortunately I can't change the current property file and have to work with it. The property file looks something like this: projectName.ClusterNameServer1.sslport=443 projectName.ClusterNameServer1.port=80 projectName.ClusterNameServer1.host=myHostA projectName.ClusterNameServer2.sslport=443 projectName.ClusterNameServer2.port=80 projectName.ClusterNameServer2.host=myHostB In their deployment scripts they basically have alot of if projectName.ClusterNameServerX where X is some number of entries defined and then do something, e.g.: if projectName.ClusterNameServer1.host != "" do X if projectName.ClusterNameServer2.host != "" do X if projectName.ClusterNameServer3.host != "" do X Then when they add another host (say Serve4) they've added another if statement. Question: What I would like to do is make the scripts more dynamic and parse the properties file and put what I need into some data structure to pass to the deployment scripts and then just iterate over the structure and do my deployment that way so I don't have to constantly add a bunch of if some host# do something. I'm just curious to feed some suggestions as to what others would do to parse the file and what sort of data structure would they use and how they would group things together by ClusterNameServer# or something else. Thanks

  • Need help/suggestions for creating fantasy sports scoring databases and queries

    - by MGumbel
    I'm trying to create a website for my friends and I to keep track of fantasy sports scoring. So far, I've been doing the calculations and storage in Excel, which is very tedious. I'm trying to make it more simplified and automated through a SQL database that I can then wrap a web app around to enter daily stat updates. It's premised on our participation in another commercial site where we trade virtual shares of athletes, and thus acquire an "ownership percentage" in each athlete. For instance, if there are 100 shares of AROD, and I own 10 shares, then I own 10%. It then applies this to traditional baseball rotisserie scoring. So, for instance, if AROD has 1 HR today, then his adjusted HR stat would be 1.10. If he also has 2 RBI's, then his adjusted RBI stat today would be 2.20, based on (2 x 1.10)(1 to normalize the stat, and the .10 to represent the ownership percentage). All the stats for my team would then be summed each day and added to my stat history to come to an aggregated total. After that, points are allocated based on the ranking of each participant in each category at the end of the day. E.g. if there are 10 participants, and I have the highest total aggregate number of Adjusted HR's, then I get 10 pts. The points are then summed across the different stat categories to come up with a total point ranking for that day. An added difficulty is that ownership %'s can change on a daily basis. So far, in playing around with different schema, I don't know that having a separate table for each athlete's stats and each player's ownership %'s is the wisest choice. It seems to me that simply having two tables, one that contains the daily stat information for each athlete, and another that shows the ownership % of each player. My friend suggested using a start and end date for each ownership % to represent the potential daily changes in this category. I'm admittedly new to database development, so any suggestions on query code would be appreciated.

  • Creating a new Guid inside a code snippet using c#

    - by Rob
    I want to make an intellisense code snippet using Ctl K + Ctl X that actually executes code when it runs... for example, I would like to do the following: <![CDATA[string.Format("{MM/dd/yyyy}", System.DateTime.Now);]]> But rather than giving me that string value, I want the date in the format specified. Another example of what I want is to create a new Guid but truncate to the first octet, so I would want to use a create a new Guid using System.Guid.NewGuid(); to give me {798400D6-7CEC-41f9-B6AA-116B926802FE} for example but I want the value: 798400D6 from the code snippet. I'm open to not using an Intellisense Code Snippet.. I just thought that would be easy.

  • Creating a fancy search bar with Swing components

    - by Kavon Farvardin
    I'm trying to come up with an elegant recreation of the search bar component in Thunderbird. The clear button doesn't appear until there is text in the box, so that screen-shot is a bit inaccurate. Should I use a layered pane and get some buttons to float above the box? (but then getting the text to not appear below the buttons would be hacky) Maybe just put buttons at the ends of the search bar and have it somehow blend in? Any ideas or maybe a style reconsideration is welcome, thank you.

  • Iteratively creating multiple file input fields in Rails

    - by David
    I have a column of product views in a database (e.g. top, bottom, front, back). I'm trying to generate a series of file inputs to allow the user to upload an image for each view. This is the result I'm after: ... <label>Top</label> <input type="file" name="image[Top]"><br> <label>Bottom</label> <input type="file" name="image[Bottom]"><br> <label>Front</label> <input type="file" name="image[Front']"><br> ... This is what I'm trying: <%= views = View.order('name ASC').all.map { |view| [view.name, view.id] } %> <%= views.each { |view| label(view); file_field('image', view) } %> However, all this does is print out the views array a couple of times. Hopefully you Rails experts can point me in the right direction. (I apologize in advance if I'm butchering Ruby.)

  • creating BeanInfo objects in NetBeans 6.1 does not work for some objects

    - by Coder
    I have recently learned about BeanInfo classes in Java, and have successfully used them to add icons to my custom GUI components which extend swing components such as JTextField, however i have a more specialized GUI component which extends from another one of my GUI components, which then extends from JTextField. Ie. the class hierarchy is of the form "A - B - JTextField". I can create a bean info object that works for class B, but when i click on the bean info editor option in netbeans to create a bean info object for class A, nothing happens. Ie. there is no error pop-up and a bean info object is not created. There isn't much difference between class A and B. Both A and B have default no argument constructors and they are very similar to each other. The only thing i can really think of is that A uses generics and B does not. I would like to create a beaninfo object for class A so that i can add custom icons for that component. Any help would be appreciated. Thanks.

  • Creating LINQ to SQL for counting a parameter

    - by Matt
    I'm trying to translate a sql query into LINQ to SQL. I keep getting an error "sequence operators not supported for type 'system.string'" If I take out the distinct count part, it works. Is it not because I'm using the GROUP BY? SELECT COUNT(EpaValue) AS [Leak Count], Location, EpaValue AS [Leak Desc.] FROM ChartMes.dbo.RecourceActualEPA_Report WHERE (EpaName = N'LEAK1') AND (Timestamp) '20100429030000' GROUP BY EpaValue, Location ORDER BY Location, [Leak Count] DESC Dim temp = (From p In db2.RecourceActualEPA_Reports _ Where (p.Timestamp = str1stShiftStart) And (p.Timestamp < str2ndShiftCutoff) _ And (p.EpaName = "Leak1") _ Select p.EpaName.Distinct.Count(), p.Location, p.EpaValue)

  • Efficiency: Creating an array of doubles incrementally?

    - by Alan
    Consider the following code: List<double> l = new List<double>(); //add unknown number of values to the list l.Add(0.1); //assume we don't have these values ahead of time. l.Add(0.11); l.Add(0.1); l.ToArray(); //ultimately we want an array of doubles Anything wrong with this approach? Is there a more appropriate way to build an array, without knowing the size, or elements ahead of time?

  • Structuremap and creating objects with initial state

    - by Simon
    I have an object which needs a dependency injected into it public class FootballLadder { public FootballLadder(IMatchRepository matchRepository, int round) { // set initial state this.matchRepo = matchRepository; this.round = round; } public IEnumerable<LadderEntry> GetLadderEntries() { // calculate the ladder based on matches retrieved from the match repository // return the calculated ladder } private IMatchRepository matchRepo; private int round; } For arguments sake, lets assume that I can't pass the round parameter into the GetLadderEntries call itself. Using StructureMap, how can I inject the dependency on the IMatchRepository and set the initial state? Or is this one of those cases where struggling against the framework is a sign the code should be refactored?

  • ZEND - Creating custom routes without overwriting the default ones

    - by Pedro Cordeiro
    I'm trying to create something that looks like facebook's profile URL (http://facebook.com/username). So, at first I tried something like that: $router->addRoute( 'eventName', new Zend_Controller_Router_Route( '/:eventName', array( 'module' => 'default', 'controller' => 'event', 'action' => 'detail' ) ) ); I kept getting the following error: Fatal error: Uncaught exception 'Zend_Controller_Router_Exception' with message 'eventName is not specified' in /var/desenvolvimento/padroes/zf/ZendFramework-1.12.0/library/Zend/Controller/Plugin/Broker.php on line 336 Not only I was unable to make that piece of code work, all my default routes were (obviously) overwritten. So I have, for example, stuff like "mydomain.com/admin", that was now returning the same error (as it fell in the same pattern as /:eventName). What I need to do is to create this custom route, without overwriting the default ones and actually working (dûh). I have already checked the online docs and a lot (A LOT) of stuff on google, but I didn't find anything related to the error I'm getting or how to not overwrite the default routes. I'd appreciate anything that could point me the right direction. Thanks.

  • Cannot Generate ParameterSetMetadata While Programmatically Creating A Parameter Block

    - by Steven Murawski
    I'm trying to programmatically create a parameter block for a function ( along the lines of this blog post ). I'm starting with a CommandMetadata object (from an existing function). I can create the ParameterMetadata object and set things like the ParameterType, the name, as well as some attributes. The problem I'm running into is that when I use the GetParamBlock method of the ProxyCommand class, none of my attributes that I set in the Attributes collection of the ParameterMetadata are generated. The problem this causes is that when the GetParamBlock is called, the new parameter is not annotated with the appropriate Parameter attribute. Example: function test { [CmdletBinding()] param ( [Parameter()] $InitialParameter) Write-Host "I don't matter." } $MetaData = New-Object System.Management.Automation.CommandMetaData (get-command test) $NewParameter = New-Object System.Management.Automation.ParameterMetadata 'NewParameter' $NewParameter.ParameterType = [string[]] $Attribute = New-Object System.Management.Automation.ParameterAttribute $Attribute.Position = 1 $Attribute.Mandatory = $true $Attribute.ValueFromPipeline = $true $NewParameter.Attributes.Add($Attribute) $MetaData.Parameters.Add('NewParameter', $NewParameter) [System.Management.Automation.ProxyCommand]::GetParamBlock($MetaData)
