  • How to use the callback method with a c++ directshow sample grabber

    - by Mr Bell
    I have a sample grabber hooked into my directshow graph, based on this example http://msdn.microsoft.com/en-us/library/dd407288(VS.85).aspx the problem is that it uses one shot and buffers. I want to continuously grab samples, and i'd rather have a callback than i guess polling for the samples. How do use the SetCallback method? SetCallback(ISampleGrabberCB *pCallback, long WhichMethodToCallback) how do I point pCallback to my own method?

  • Java Calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY), will it roll backwards, forwards or unknow

    - by Will
    Suppose the following code is executed on the 22nd of August 2009 (a Saturday) Calendar c = Calendar.getInstance(); c.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY); c.get(Calendar.DAY_OF_MONTH) will return 23. I'm interested in the conditions is would return 14 (last Sunday, rather than the next Sunday). Are there any rules associated with the direction Calendar will roll the DAY_OF_MONTH/YEAR when DAY_OF_WEEK is set? If so what are they?

    Does anyone know how to embed WYSIWYG editor in multiline TextField? I need rather complex editor such as TinyMCE, but I can't get it working with Mojo widgets. Maybe, I'm doing something wrong? If there's a way to do it, please, give me some pointers! Thanks in advance, Mikhail.

  • Colorbox not working in IE

    - by John Isaacks
    on This page in the center is a button that says "request price". I am using Colorbox so that when you click it, there is a lightbox-type popup of a Flash app. This works fine in FF and Chrome. However in IE it is just taking you directly to the page containing the flash rather then making it a popup. Does anyone have a clue why?

  • Passing array by ref.

    - by atch
    Ref. to my last post and sellibitze's comment to that post on passing array by ref rather than by value, why is it that when I'm passing array by value compiler can deduce arguments but it won't do it if I pass it by value? @Paul So just to make it clear when I'm declaring fnc: void f(int a[]);//I'm passing a pointer but when I'm declaring: void f(int &a[]);//I'm passing a ref? Do I understand this correctly now?

  • Show milliseconds with Android Chronometer

    - by Matthew Steeples
    I'm looking for a way to make the Chronometer in Android (preferably 1.6 and upwards) show 10ths of a second while counting up. Is it possible to do this? If not, is there a free (and preferably open source) library that does the same? Failing that I'll write my own, but I'd rather use someone else's!

  • DateTimePicker replacement that "respects" e.g. the CurrentUICulture

    - by S.C. Madsen
    Apparently the DateTimePicker does not "respect" or adhere to the CurrentUICulture of a .NET application, because DateTimePicker is a "Native" Common-control with a .NET wrapper (I think). I have a requirement to display "AM/PM" regardless of the regional settings of the PC running my .NET Winforms application. I would rather not re-implement my own DateTimePicker control, which adheres to the CurrentIUCulture. So does anybody know of a work-around or have a link to DateTimePicker control re-implementation?

  • MOSS 2007 Pre-Populate SSO Credentials

    - by CaffeineFueled
    I'm looking to set a user's credentials for a particular webpart/application that utilizes the SSO database within Sharepoint. Can someone point me to a code sample of how I might do this in .net? The webpart/application typically stores the user's credentials upon the first use but I'd rather they not even be bothered with entering them at all.

  • Textmate RSpec Run Example fails

    - by Barb
    When I try to run an RSpec example from within Textmate. I get "Rails requires RubyGems = 1.3.2 (you have 1.3.1). Please gem update --system and try again." I run gem update and I get nothing to update. I think the RSpec bundle is running from the built in directories rather than /local/. How do I change where the bundle looks? Thanks! :)

  • UIView shadow drawing wrong

    - by dc
    Trying to draw a shadow using code from this question: http://stackoverflow.com/questions/805872/how-do-i-draw-a-shadow-under-a-uiview I implement it in a UIView subclass as discussed, but when I try and use it using UIView *shadow = [[ShadowView alloc]initWithFrame:CGRectMake(100,100,100,100)]; I get only a black square, rather than something resembling shadow. Am I missing something here?

  • "SSH server" in Windows?

    - by Benjamin Oakes
    I have some command-line commands to execute on a Windows machine. The programs I need to run are only available on Windows. Is there a way to easily to do something like I would do with SSH? Example of what I mean: ssh [email protected] "remote command to execute" ...or do I have to Remote Desktop just to do this? (I'd like to run the commands programmatically from another computer rather than running them by hand.)

  • UISwitch propagate state

    - by Reonarudo
    Hello, I'm still rather new to iPhone development and I tried something I didn't it was possible. I have a UIView for my TableView Section Header with a switch on it, and I also have a UITableCellView with another Switch on it. It all looks fine, but now I want to propagate the UISwitch state from the section header to all the UISwitches on the section rows. Can anyone enlighten me how can I accomplish this? Thank you.

  • Programmers - I have a question for you.

    - by jens
    My boyfriend does coding (Rails/C?/PHP) for a job and I don't know what he would appreciate on our first anniversary. Does anyone have any ideas? Yes, he's stereotypical geek, but I'd rather not give a pack of Bawls for an anniversary gift. He dislikes going anywhere, so "experiences" like going to an event are out. Maybe I should just have a giant LAN party in the house.

  • Mercurial Queues: combining patches

    - by Eamon Nerbonne
    I've been playing with Mercurial and mercurial queues, and now have a fairly reasonable working version. However, before I submit a patch, I'd like to take that spagetti-history and merge it into discrete, logical steps, rather than the semi-overlapping repeated do-undo-redo-slightly-differently mess it is now, if only to reduce the number of patches. How do I do that?

  • Can Rational Team Concert and IntelliJ coexist?

    - by Paul McKenzie
    I am a long time intellij user. The company where I work is likely to introduce Rational Team Concert to our department shortly. I went to the RTC demo and it looks like a reasonable product, built around Eclipse, but I would rather not give up using IntelliJ. Does anyone have experience of using non-eclipse IDEs with RTC?

  • QTableWidget: How can I get tighter lines with less vertical spacing padding?

    - by Dirk Eddelbuettel
    The QTableWdiget is fabulous for simple grid displays. Changing colors, fonts, etc is straightforward. However, I did not manage to give the grid a 'tighter' look with less vertical whitespace. I see that the Qt documentation talks (eg here) about margin border padding around widgets, but when I set these I only get changes around the entire grid widget rather than inside. How can I set this (with a style sheet, or hard-coded options) directly to make the QTableWidget display tighter?

  • Basic image processing question

    - by indoman
    Can you enlarge a feature so that rather than take up a certain number of pixels it actually takes up one or two times that many to make it easier to analyze? Would there be a way to generalize that in MATLAB?

  • How are distributed services better than distributed objects?

    - by Gabriel Šcerbák
    I am not interested in the technology e.g. CORBA vs Web Services, I am interested in principles. When we are doing OOP, why should we have something so procedural at higher level? Is not it the same as with OOP and relational databases? Often services are supported through code generation, apart from boilerplate, I think it is because we new SOM - service object mapper. So again, what are the reasons for wervices rather than objects?

  • Are all swf files open source

    - by Behrooz Karjooravary
    I am new to flash. Does anyone know if the swf files which are sold in istockphoto are open source. I want to purchase this flash piano but i would have to change some of its functionality so I need to make sure it's possible before i purchase. For instance I need it to play a sound on hover not on mouse press. And I'd like it to play my own piano sound samples rather than the ones it comes with. Thanks
