  • WCF wrapper COM object

    - by LarryR
    I have a third party COM component (they don't offer a .Net assy), that has the additional feature that it only works under x86 compile. I am trying to wrap this in a WCF service, but if I select x86, the service won't start (System.BadImageFormatException). Any workarounds for this ? Thanks Larry

  • Using Interface Builder tags

    - by pat
    I'm using interface builder's tag feature to access some UILabels I'm instantiating in a xib file. Since this a UITextViewCell I want to avoid superfluous method calls, but I want to do it right too. Thus when I do: UILabel *label = (UILabel *)[cell viewWithTag:1]; I'm wondering if I should wrap it up like so: if([[cell viewWithTag:1] isKindOfClass [UITableViewCell class]]) { UILabel *label = (UILabel *)[cell viewWithTag:1]; } Any discussion on this would be appreciated. Thanks

  • malloc and delete in C++, opinions

    - by Alexander
    In C++ using delete to free memory obtained with malloc() doesn't necessarily cause a program to blow up. Do you guys think a warning or perhaps even an assertion failure should be produced if delete is used to free memory obtained using malloc()?? Why do you think that Stroustrup did not had this feature on C++?

  • Storing dynamic fields in Django forms

    - by hekevintran
    Django's form library has a feature of form sets that allow you to process dynamically added forms. For example you would use form sets if your application has a list of bookmarks you could use form sets to process multiple forms that each represent a bookmark. What about if you want to dynamically add a field to a form? An example would be a survey creation page where you can dynamically add an unlimited number of questions. How do you handle this in Django?

  • Create a overlay screen while a game/program is running?

    - by Dodi300
    Hello. Does anyone know how I can create a screen overflow while a program is running? Mainly while a game is running. If anyone has used xFire or Steam, these use this feature. I've created a winform which starts the game/program and then minimizes. Could the overflow be created in the same winform? Thanks for the help! :)

  • C#, introduce a DragOver delay

    - by user275587
    In my application I catch a DragOver event and then perform an action. I'd like to wait for half a second before performing the action, the action should not be performed after that delay if the drag operation has ended. The only way I could think of to implement this feature is something like this: Function DragOver Event If TimerTimeReached Then PerformDragAction Else If Not TimerStarted StartTimer End End Function Function DragLeave Event If TimerStarted StopTimer End End Function Is there a better way to perform this operation?

  • How to enable nullptr from C++0x in the Visual C++ 2010?

    - by Sorin Sbarnea
    I wonder how can I enable the nullptr in the just released Visual Studio 2010. (C++ project, not managed). This is one of the new features but it is not available by default and looking inside the documentation at http://msdn.microsoft.com/en-us/library/4ex65770(VS.100).aspx it seams that it is enabled by /clr but this is managed! Is this a feature added only for .NET?

  • Office Web Components compatibility issues

    - by Sebastian
    Hello, I'm doing some research on the convenience of using Office Web Components on a web to show pivot tables and graphics and I have a question regarding this. Does the use of these components will turn my web app (at least for this feature) into a "Internet Explorer only" app Thanks in advance!

  • Automatically add "More..." Tab in Android

    - by ZelluX
    Hi, all I'm writing an application which contains many tabs, and sometimes the number of tabs may exceed five. So I want to make it behave like iPhone, which is, move additional tabs to a "More..." tab. I would like to know if this feature is supported by TabHost, or if there is any existing open source widget which can do the favor for me. Thanks.

  • Vertical text alignment in Crystal Reports?

    - by George Mauer
    In the Crystal Reports editor that comes with Visual Studio (2008) is it possible to align text to the center of a text box rather than to the top? I can't find the option anywhere and a Google search is not encouraging but I just can't bring myself to believe that they would not include such an obvious feature.

  • How to search a MySQL database for a specific string

    - by Nadia
    I am trying to set up a search feature on my site that will only return exact matches to keyword entered by the user. So if the user searches "dog" I don't want an article titled "Doggy Style" to appear in the search results (just an example I don't really have an article by that name). This of course does exactly that: SELECT * FROM articles WHERE article_title LIKE '%$searchQuery%' $searchQuery here is a PHP variable taken from the user's input form. So is there any way to return only exact matches?

  • How to know user is dragging something when the cursor is not in my window?

    - by Edwin
    Hi folks, We all know you can implement drag-and-drop feature for your Window so that it accepts drag and drop operation, but my question is, how to detect a drag-and-drop operation that's is in progress in other windows, for example, dragging a file in the Windows Explorer? What I want to do is that when a user is dragging a file then my hidden window shows up. Thank you!

  • Scrum stories and behind the scenes features

    - by James P.
    As I understand things, the Scrum backlog is composed of a series of Stories that represent something for the end user and this is further decomposed into Features. If this is the case, where does all the behind the scenes features go that aren't really linked to a story but are still useful? For example, say I'm making an application that catalogs the contents of a hard drive. A story wouldn't require it but having an md5 hash on each file would be a nice feature.

  • How is "Make Object ID" implemented in the .NET debugger?

    - by Omer Raviv
    Hi, I would like know how this feature is implemented in VS - I understand it holds some sort of weak-reference to the object in the debugged-application's memory, but how exactly is it accomplished? I know simply tracking the address (as in native code) wouldn't work, because the GC might move the object about, invalidating the address. Thanks.
