• Casting DataTypes with DirectCast, CType, TryCast

  - by Alex Essilfie

  Ever since I moved from VB6 to VB.NET somewhere in 2005, I've been using CType to do casting from one data type to another. I do this because it is simply faster, used to exist in VB6 and I do not know why I have to be using DirectCast if there is apparently no difference between them. I use TryCast once in a while because I understand that sometimes casting can fail. I however cannot get the difference between CType and DirectCast. Can anyone tell me the difference in plain simple English what the difference the two (CType and DirectCast)? Adding examples of where to use what as well would be helpful. Thanks.

• MYOB Service Sales Import

  - by sjw

  I have developed an export file from our Job Management system that I want to be able to import into MYOB Accounting Plus v18.5. The file is generated without issue and I have included every single field to make it easy for upload (i.e. Match All matches every field) The problem I am having is no matter what I do, I cannot get the sales to import... Every time, no matter what I do or how I create the customer card comes back with: Error -190: Customer not found. Sale invoice not imported. I have tried matching using - co./Last Name, Card ID & Record ID and every time I get the same error. I have created a single customer with a simply Co./Last Name, Card ID & Record ID and still, when I try to import using these same fields exactly matched, I get the same error...

• Custom editor in QAbstractTableModel

  - by Martin Beckett

  Does anyone have an example of using a QWidget as an editor in a QAbstractTableModel? I have a column which when edited should create a QCombobox with the list of choices. The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole. Note - the combo box contents are the same for every row and it only needs to be shown when somebody clicks in the cell. I know this should be simple but I can't get it to work. It's easy for a QTableWidget based table - but I need it for a very large data table.

• Embedded Linux: Memory Fragmentation

  - by waffleman

  In many embedded systems, memory fragmentation is a concern. Particularly, for software that runs for long periods of time (months, years, etc...). For many projects, the solution is to simply not use dynamic memory allocation such as malloc/free and new/delete. Global memory is used whenever possible and memory pools for types that are frequently allocated and deallocated are good strategies to avoid dynamic memory management use. In Embedded Linux how is this addressed? I see many libraries use dynamic memory. Is there mechanism that the OS uses to prevent memory fragmentation? Does it clean up the heap periodically? Or should one avoid using these libraries in an embedded environment?

• CSS3 box-shadow + inset + RGBA

  - by mkotechno

  I'm doing some tests with new features of CSS3, but this combination only works in lastest versions of Chrome and Firefox, but not in Safari or Opera: box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -webkit-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -moz-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); I really don't know if they fails in the box-shadow itself, in the inset parameter, or in RGBA color. It's a syntax error or simply Safari and Opera lacks on this?

• Static classes in PHP via abstract keyword?

  - by Boldewyn

  According to the PHP manual, a class like this: abstract class Example {} cannot be instantiated. If I need a class without instance, e.g. for a registry pattern: class Registry {} // and later: echo Registry::$someValue; would it be considered good style to simply declare the class as abstract? If not, what are the advantages of hiding the constructor as protected method compared to an abstract class? Rationale for asking: As far as I see it, it could a bit of feature abuse, since the manual refers to abstract classes more as like blueprints for later classes with instantiation possibility.

• Safari extension cookies not recognized/passed

  - by Alex

  I've recently been porting a Chrome extension to Safari, and encountered this kind of error (bug, feature, etc.) So, in global page i have a XMLHTTP request to a secure page which is available only after you login. Example: I simply login using browser - as usually you do on facebook or other secure pages After that, in global page, I load a login-only-available xmlhttp - and it says i'm not logged in it seems that global page somewhat has it's own cookies, so a secure page thinks i'm new ps: in Chrome i can load that page and it thinks i'm acting on behalf of logged in user, so i guess there are some restrictions in Safari pps: i heard there's a Block third-party cookies option in Safari, but even if i checked it to "Never block" it still doesn't work

• What is the difference between these two different lines of Objective-C, and why does one work and n

  - by jrtc27

  If I try and release tempSeedsArray after seedsArray = tempSeedsArray , I get an EXEC_BAD_ACCESS, and Instruments shows that tempSeedsArray has been released twice. Here is my viewWillAppear method: - (void)viewWillAppear:(BOOL)animated { NSString *arrayFilePath = [[NSBundle mainBundle] pathForResource:@"SeedsArray" ofType:@"plist"]; NSLog(@"HIT!"); NSMutableArray *tempSeedsArray = [[NSMutableArray alloc] initWithContentsOfFile:arrayFilePath]; seedsArray = tempSeedsArray; NSLog(@"%u", [seedsArray retainCount]); [seedsArray sortUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; [super viewWillAppear:animated]; } seedsArray is an NSMutableArray set as a nonatomic and a retain property, and is synthesised. However, if I change seedsArray = tempSeedsArray to self.seedsArray = tempSeedsArray (or [self seedsArray] = tempSeedsArray etc.), I can release tempSeedsArray. Could someone please explain simply to me why this is, as I am very confused! Thanks

• PHP: How should I move my code from dev to production?

  - by Teddy

  I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?

• LINQ to SQL: On load processing of lazy loaded associations

  - by Matt Holmes

  If I have an object that lazy loads an association with very large objects, is there a way I can do processing at the time the lazy load occurs? I thought I could use AssociateWith or LoadWith from DataLoadOptions, but there are very, very specific restrictions on what you can do in those. Basically I need to be notified when an EntitySet< decides it's time to load the associated object, so I can catch that event and do some processing on the loaded object. I don't want to simply walk through the EntitySet when I load the parent object, because that will force all the lazy loaded items to load (defeating the purpose of lazy loading entirely).

• Reverting CoreData data

  - by ndg

  I have an NSTableView which is populated via a CoreData-backed NSArrayController. Users are able to edit any field they choose within the NSTableView. When they select the rows that they have modified and press a button, the data is sent to a third-party webservice. Provided the webservice accepts the updated values, I want to commit those values to my persistent store. If, however, the webservice returns an error (or simply fails to return), I want the edited fields to revert to their original values. To complicate matters, I have a number of other editable controls, backed by CoreData, which do not need to resort to this behaviour. I believe the solution to this problem revolves around the creation of a secondary Managed Object context, which I would use only for values edited within that particularly NSTableView. But I'm confused as to how the two MOC would interact with each other. What's the best solution to this problem?

• Apache issue with subdomains

  - by mike

  I just setup a subdomain with the following RewriteCond: RewriteCond $1 !^search.php$ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^/?([^/]+)$ search.php?q=$1 [L,NS] I'm using the same rewrite condition on my main domain and it works perfectly. However, when I set it up on the subdomain, it simply outputs "index.php" when going to http://subdomain.domain.com Every page on the subdomain outputs the page name in the body instead of processing the code, except for the search page, which appears to be working correctly. Any idea why every page but the search page works? What can I do to correct it?

• Adding an equation or formula to a figure caption in LaTeX

  - by gotgenes

  I have a figure in LaTeX with a caption to which I need to add a formula (equation* or displaymath environments). For example: \documentclass[12pt]{article} \begin{document} \begin{figure}[tbph] \begin{center} %... \end{center} \caption{As you can see \begin{displaymath}4 \ne 5\end{displaymath} } \label{fig:somefig} \end{figure} \end{document} This makes pdflatex angry, though it will produce a PDF. ! Argument of \@caption has an extra }. <inserted text> \par l.9 } What's the right way to go about adding an equation to a figure caption? NOTE: Please do not suggest simply using the $ ... $ math environment; the equation shown is a toy example; my real equation is much more intricate. See also: Adding a caption to an equation in LaTeX (the reverse of this question)

• Syncing with Address Book: Last modified property in ABPerson/ABRecord

  - by Oliver

  I'm syncing data from the Address Book into a Core Data database and I've nearly got it working perfectly. The only issue remaining is checking for changes and modifications on startup and reflecting the changes inside Core Data. Currently, I simply check the ID of each ABRecord and see if it is already in Core Data. Of course, this only works in the case of new contacts and not changed information inside an existing contact. One solution would be to go through each contact already in the database and check each property against the Address Book. The down side of this is that it's really slow. One method that would work is if the ABRecord had a last modified date. I could then store the date inside the Core Data database and check on startup to see if I need to update the contact. However, I can't find anything like this in the documentation. Any ideas?

• Adding WCF service reference adds DataContract types too

  - by Avi Shilon

  Hi everybody, I've used Visual Studio's Add Service Reference feature to add a service (actually it is a workflow service, created in WF4 RC1, but I don't think this makes any difference), and it also added the DataContracts that the service uses. At first this seemed fine, because All I've had in the DataContracts was simply properties, with no implementations. But now I've added code in the constructor of one data contracts that initializes creates an instance of one of the properties that exposes a list of other DCs, and when I've updated the service reference via VS (2010 RC1), the implementation was not updated. What should I do? Should I use my DCs instead of the ones created by VS or should I use the ones VS created? I've noticed that the properties in the VS-generated DCs contain some additional logic for checking equality in the setters and they also implement some interfaces too (like IExtensibleDataObject and INotifyPropertyChanged) which might get handy I guess in the future (I'm not knowledgeable at WCF). Thank you for your time folks, Avi

• Setting the ASP.NET version via MSBUILD

  - by dovholuk

  I am trying to create a new website on a remote server via msbuild (I like to call it "msdeploy"). I've downloaded and used the SDC tasks, the MSBuildExtension tasks and the MSBuildCommunity tasks but I simply can't get it right. I figure that WebDirectorySetting (from MSBuild.Community.Tasks.IIS) is my best bet but I can't find the right SettingName to pass. I'd like to use some sort of MSBuild task to accomplish this but maybe it just doesn't exist. Custom VBS or WMI are my last resort... Thanks

• Best data-structure to use for two ended sorted list

  - by fmark

  I need a collection data-structure that can do the following: Be sorted Allow me to quickly pop values off the front and back of the list Remain sorted after I insert a new value Allow a user-specified comparison function, as I will be storing tuples and want to sort on a particular value Thread-safety is not required Optionally allow efficient haskey() lookups (I'm happy to maintain a separate hash-table for this though) My thoughts at this stage are that I need a priority queue and a hash table, although I don't know if I can quickly pop values off both ends of a priority queue. I'm interested in performance for a moderate number of items (I would estimate less than 200,000). Another possibility is simply maintaining an OrderedDictionary and doing an insertion sort it every-time I add more data to it. Furthermore, are there any particular implementations in Python. I would really like to avoid writing this code myself.

• Where does C# and the .NET Framework fail?

  - by Nate Bross

  In my non-programming life, I always attempt to use the approprite tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, powershell, batch files, and Java, as well as being versed in the web technologes (javascript, html/css). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. The bottom line here, is that I feel that I'm choosing C# and .NET simply because I am very comfertable with it, so I'm looking for cases where you have chosen something other than .NET, even though you are primarly a .NET developer.

• Infopath form publishing and root content type ?

  - by Steve B

  Hi, I have several infopath 2010 form template that I want to publish to a form library in SharePoint 2010 Server with enterprise CaL. All of this forms have a common part (a template part actually). Is it possible to define a common "parent" content type of this forms ? In fact, I want : Form content type (SP OOB) My root form content type, with standard columns "requester", "process name", etc. Form 1 Form 2 etc. other unrelated form 1 other unrelated form 2 Instead of the standard behavior : Form content type (SP OOB) Form 1 Form 2 other unrelated form 1 other unrelated form 2 etc. Behind this question I want to be able to create a dashboard of all form request using a content query web, by simply specifying the content type ... One last word: the idea is to allow a customer (assuming its knowledge is limited to IP 2010 basic form design). So I can't accept answers like "extract files, use a text editor and hack the xsf file"... thx in advance

• How to place text on top of image in ReportViewer

  - by Christoffer

  I feel very silly asking this, since it seems like it just should work, but I cannot make it work and cannot find anything in the documentation about this. The problem: I'm developing an application in Visual Studio 2010 that is utilizing ReportViewer, rendering the report locally. In the report designer, I place a textbox on top of an image. This looks fine in the designer, but when rendering the report, the textbox is rendered below the image. Now, before you suggest it, I have tried placing a textbox on top of a rectangle (or other control) with the BackgroundImage property set. This works. But: I cannot find a way to rescale the background image to fit the control. Setting a different dpi for the background image does nothing. Simply rescaling the image to a different resolution is not an option, since I eventually want to print the report. Does anybody have a solution to this?

• Load balancer - how to write one for a custom application?

  - by Poni

  Hi! I've written a simple server application which will run distributed on several machines. My question is how does a network load balancer works, in general? I've heard of round-robin and other algorithms, but what I haven't got answer to is how does the process really goes? In socket terms. The client connects to one of the load balancer machines, asks for a "free-to-connect-to" server and simply connects to it? That's the simpliest way I can think of. .. or, does it use the load balancer as a proxy (that implies that all the NBs must be always connected to the application servers, and data is transferred through them)? It's more of a general question. How would you do this? Thank you all!

• jQuery: delegating clicks to elements that contain other elements

  - by Master Morality

  So i get the gist of $.delegate and I know why it's doing what it's doing, but I'm wondering if there is a work around. I have link elements that contain spans like so: <a href='#'> <span>Person Name</span> <span>Person Info</span> </a> I use the following code in jQuery for event delegation: containerElement.delegate('click','a',function(){...}); The trouble is that this only triggers when I click on white space not occupied by a span. I know it does this because delegate simply compares the event target to 'a' to check if it should fire the delegate, however I want to include the spans as well, pretty much anything inside the <a>...</a> what do?

• Proper way to build a data Repository in ASP.NET MVC

  - by rockinthesixstring

  I'm working on using the Repository methodology in my App and I have a very fundamental question. When I build my Model, I have a Data.dbml file and then I'm putting my Repositories in the same folder with it.... IE: Data.dbml IUserRepository.cs UserRepository.cs My question is simple. Is it better to build the folder structure like that above, or is it ok to simply put my Interface in with the UserRepository.cs? Data.dbml UserRepository.cs              which contains both the interface and the class Just looking for "best practices" here. Thanks in advance.

• reply to a comment via email and directly post it on the website commenting system

  - by Gaurav Sharma

  Hello Everybody, I have developed a website using PHP and MYSQL. The website has a commenting system through which registered users of the website can post comments on the feedback posted by different users. When a comment is posted for a feedback an email is sent to the user who posted that feedback notifying him of new comments on his feedback. Now what I want is that a feedback owner should be able to post a new comment in response to that comment by simply replying to the email that has been sent by the website. I hope I was able to explain my query properly. If it needs any improvement in explanation, I would be glad to know and make changes accordingly Thanks

• How do I prevent a font from extending off the top of a textbox?

  - by David Ellis

  I'm using a barcode font (IDAutomationMC39H) in an SSRS 2005 report I'm developing, and while it renders fine in the preview in BIDS, if I export the results to PDF, print the results, or do any of the above (including preview) in Report Manager, the barcode font is extending off the top of the textbox. The barcode itself is nearly 20px tall, even at only a 12pt size. I've tried changing the CanGrow value for the textbox, but it seems that even with that set off the barcode isn't pushing the bottom edge of the textbox downwards, it's simply extending over the top of the box. I've also tried resizing the textbox to allow it to contain the entire height of the font, but even with the VerticalAlign set to Bottom the barcode still sticks to the top of the textbox and overflows out the top. See screenshot here: http://bit.ly/9UfycP Does anyone know how to force the font to be bound by the top of the box, instead of overlapping it?
