  • How to get the form active control?

    - by PabloG
    Is there a way to get the form active control? I was checking in the help for the "Support.GetActiveControl" method but it isn't supported :) for the Compact Framework. I suppose that I can track the focus by adding a custom GotFocus event handler to all the form controls, but I'm looking for a more generic way that can be implemented for any form.

  • scraping blog contents

    - by goh
    Hi lads, After obtaining the urls for various blogspots, tumblr and wordpress pages, I faced some problems processing the html pages. The thing is, i wish to distinguish between the content,title and date for each blog post. I might be able to get the date through regex, but there are so many custom scripts people are using now that the html classes and structure is so different. Does anyone has a solution that may help?

  • How to analyze PermGen contents?

    - by Daniel
    I want to get a dump of the PermGen to see why it is filling. Is there a way to analyze this? I already know about the common suspects like log4j, tomcat webapp reloading etc, but I have some custom proxy generation code in my application, too, and just want to look under the hood. Is this possible somehow?

  • Recommendations for a programmable drivers license scanner?

    - by Slapout
    Our motor pool wants to scan drivers’ licenses and have the data imported into our custom system. We're looking for something that will allow us to programmatically get the data from the scanner (including the picture) and let us insert it into our application. I was wondering if anyone has had experience with this type of system and could recommend one or tell us which ones to avoid. Our application is written in PowerBuilder and uses a DB2 database.

  • How to change the outlining hover color in VS 2010?

    - by RCIX
    If i hover over the thin vertical bar on the left, it highlights the entire scope of the block that's to the right. When this scope is large, my entire screen flashes white (a consequence of my custom color scheme). Is there a way to change that color? i don't recall there being one when i made the theme.

  • Is there a good .Net CSS aggregator that combines style sheets and minifies them?

    - by vfilby
    I am looking to see if there is an open source/free project that provides a CSS manager. I am looking for this mainly for performance tweaking and hoping there is a readymade project rather than building from scratch. Features I am looking for include: Combines multiple .css files into a single css file Optionally minifies the resulting .css file Works well with .Net (a user control, custom handler, etc) Is there a project out that that handles this?

  • Navigation properties not set when using ADO.NET Mocking Context Generator

    - by olenak
    I am using ADO.NET Mocking Context Generator plugin for my Entity Framework model. I have not started on using mocks yet, just trying to fix generated entity and context classes to make application run as before without exceptions. I've already fixed T4 template to support SaveChanges method. Now I've got another problem: when I try to access any navigation property it is set to null. All the primitive fields inherited from DB table are set and correct. So what I am doing is the following using (var context = MyContext()) { var order = context.Orders.Where(p => p.Id == 7); var product = order.Products; } in this case product is set to null. But that was not a case while using default code generator, it used to return real product object. Thanks ahead for any suggestions!

  • View / ViewModel - what is the sense (in a WPF control)?

    - by TomTom
    Not as funny as it sounds. Normally the View / ViewModel should decouple the presentation from the business logic. Good. Now, a Control in WPF is basically invisible unless made different (with the exceptions of UserControl and Window that have XAML directly attached). The Style is putting in the "visual presentation" - which basically means a Control does not need a view mechanism as WPF already has one? In addition. the ViewModel is actually part of the Control, or? Just fighting with that stuff. I know in ASP.NET, WinForms the separation makes a lot of sense - but there, basically, controls HAVE an intrinsic look. In WPF, I have some where it makes sense (derived from UserControl), but for the majority of the controls I write, the View & ViewModel look like pretty much totally superflous thanks to the already presenting view mechanism.

  • Why and when should one call _fpreset( )?

    - by STingRaySC
    The only documentation I can find (on MSDN or otherwise) is that a call to _fpreset() "resets the floating-point package." What is the "floating point package?" Does this also clear the FPU status word? I see documentation that says to call _fpreset() when recovering from a SIGFPE, but doesn't _clearfp() do this as well? Do I need to call both? I am working on an application that unmasks some FP exceptions (using _controlfp()). When I want to reset the FPU to the default state (say, when calling to .NET code), should I just call _clearfp(), _fpreset(), or both. This is performance critical code, so I don't want to call both if I don't have to...

    - by Pradyot
    autoexp.dat does not seem to take affect in Visual Studio C++ 2005 debugger. I am not trying to add any custom rules. Just want commonly used stuff like stl::string, to display in a friendlier manner. Does anyone know. how I can accomplish this? Is this just question of specifying a path to the autoexp.dat file somewhere. The file is available under the Visual Studio installation directory.

  • Why do encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom components in JSF so I've noticed only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • Correct way to read configuration file and using configuration values

    - by Harza
    I'm reading applications .config file using .NET ConfigurationManager like it should be done, but .... Which one is most preferred option: Read config and store instance of (build in or custom) ConfigurationElement for later use Read config and store only needed values (but not instances of ConfigrationElement classes) for later use Read ConfigurationElement from config always when configuration values are needed These two things are in my mind: Performance impact in case 3 when reading config all the time Problems occuring in case 1 when using cached instances of ConfigurationElements
