  • C# and Winforms TextBox control: How do I get the text change?

    - by Billy ONeal
    I have an event handler for the TextBox.TextChanged event on a form of mine. In order to support undo, I'd like to figure out exactly what has changed in the TextBox, so that I can undo the change if the user asks for it. (I know the builtin textbox supports undo, but I'd like to have a single undo stack for the whole application) Is there a reasonable way to do that? If not, is there a better way of supporting such an undo feature?

  • Notify user on database change? JavaScript/AJAX

    - by Andreas Carlbom
    Yo. I'm really quite new to this whole JavaScript business, not to mention AJAX, so I was thinking if you guys could help me out with a conundrum. Basically, what I want is for the user to be notified upon a change in a value of a MySQL table. How should I go about that? Should I use jQuery, or can I slap something together myself? Thankful for any and all replies.

  • How would you handle making an array or list that would have more entries than the standard implemen

    - by faceless1_14
    I am trying to create an array or list that could handle in theory, given adequate hardware and such, as many as 100^100 BigInteger entries. The problem with using an array or standard list is that they can only hold Integer.MAX_VALUE number of entries. How would you work around this limitations? A whole new class/interface? A wrapper for list? another data type entirely?

Thanks all,

  • Silverlight: Set Items Widths in ItemsControl to Stretch

    - by Tom Allen
    I've got an ItemsControl which fills from top to bottom, but I can't get it's child items to occupy the whole width of the ItemsControl: I basically need to stretch the green bits to fill the width of the control (as shown by the blue bits). I've tried things like setting the HorizontalAlignment property of the template item to Stretch and I've even tried binding it's Width property to the ItemsControl Width, but neither worked. Should be a straight forward one, but it's something I just can't quite figure out...

  • Shutterfly Order API . .

    - by oo
    I found this site http://www.shutterfly.com/documentation/api_OrderImage.sfly but there are no examples of actually walking through the whole process. Does anyone have any good documentation on using this API to take a local photo and allow someone to order a print via shutterfly?

  • NHibernate query CreateCriteria

    - by Jacob
    Is it possible to chose what columns I want in return from Session.CreateCriteria() ? egz.: var x = session.CreateCriteria(); x.CreateAlias("EmployeePosition", "employeePosition"); x.Add(Restrictions.Eq("employeePosition.Name", "Developer")); and is there a way to add something like "select LastName" to avoid downloading the whole row.

  • Naming convention when casually referring to methods in Java

    - by polygenelubricants
    Is there a Java convention to refer to methods, static and otherwise, any specific one or the whole overload, etc? e.g. String.valueOf - referring to all overloads of static valueOf String.valueOf(char) - specific overload, formal parameter name omittable? String.split - looks like a static method, but actually an instance method Maybe aString.split is the convention? String#split - I've seen this HTML anchor form too, which I guess is javadoc-influenced Is there an authoritative recommendation on how to clearly refer to these things?

  • Java regex return after first match

    - by user216915
    hi how do i return after the first match of regular expression? (does the Matcher.find() method do that? ) say I have a string "abcdefgeee".

  • cocoa - converting a double to string

    - by Mike
    I have a double number and I would like to convert it to string. The number is, for example, something like 24.043333332154465777... but if I convert it to string using something like NSString *myString = [NSString stringWithFormat:@"%f", myDouble]; The string is just 24.043333 how do I get a full string the corresponds to the whole double number? What other methods do I have to convert this?

  • Timeline graph - how to handle "time gaps"?

    - by ebae
    I've been working with Google chart API and annotated timeline. Drawing graphs is fine. I have no problem. However, I need to draw a timeline graph for share prices. And as you may know, share prices are meaningful only between certain times (e.g. from 10AM to 4PM, when the market opens and closes). How do I change the Google timeline graph so that on X-Axis, the range is from 10AM-4PM? Right now, it just draws a long constant line between 4PM till 10AM next day before prices start to move again. Man, I hope that makes sens. (Google finance chart seems to do it). Thank you SO much for whoever can answer. You are a CHAMPION!

  • Any experience with CryptoObfuscator or CryptoLicensing?

    - by anon2009
    Hi, I'm on the market for a good (and cheap) .Net obfuscator. I'm developing a .Net windows forms application. I evaluated IntelliLock and SmartAssebly so far. I quit the first on lack of support (I sent two emails with no response, no support site, etc). SmartAssebly looks pretty good but is too rich for my blood. Has anyone used CryptoObfuscator? Any good or bad experiences? Once, I have you here, what about CryptoLicensing? Thanks

  • Best language to learn complementing java

    - by danielrutledge
    Hi all, I'm a somewhat experienced java ee developer, and I wish to complement my background by learning a newish language. I'm recently out of school where I did a ton of scientific computing and some functional programming, so I'm pretty comfortable with those families of languages. If at all possible, I'd like to pick a language with some market value, though I know this is tough to gauge. After snooping around a bit, the consensus seems to be one of Python/Ruby/Perl; how would each of these work with java in a web application environment, and in your opinion which complements it best? Any other suggestions for languages would also be welcome.

  • Comparing file contents in F#

    - by Bartosz Milewski
    I wrote a quick and dirty function to compare file contents (BTW, I have already tested that they are of equal size): let eqFiles f1 f2 = let bytes1 = Seq.ofArray (File.ReadAllBytes f1) let bytes2 = Seq.ofArray (File.ReadAllBytes f2) let res = Seq.compareWith (fun x y -> (int x) - (int y)) bytes1 bytes2 res = 0 I'm not happy with reading the whole contents into an array. I'd rather have a lazy sequence of bytes, but I can't find the right API in F#.

  • How to create a backpropagation neural network in neurondonet?

    - by Suraj Prakash
    I am doing stock market prediction using ANNs in c#.net. I am using NeuronDotNet for the neural part. I have to give eight inputs to the network, with a hidden layer consisting 8 nodes and a single node output layer. Can anybody please give me some coding ideas for this???? This project was not a AI course assignment, but my major project. I have studied about the stocks and found various factors that affected the future value of stock of a company. Now I have to use these factors as input to the neural network. I am not getting into how to implement these factors in the neural network. I have just decided to use those eight factors as eight nodes in the input layer but things are going complex. My concern is to use these factors as input and train the neural network for output as next day's stock value. What major things should I have to care about??

  • Alternatives to Google Earth for sat image

    - by Martin Beckett
    I've been asked to add Google Earth images to a desktop app (civil engineering modelling app) I was under the impression that Google's license didn't allow you to do this. Are there any other easily accessible, and similarly high resolution, image sources anyone can recommend (Blue Marble, terraserver) ? As a bonus, any library that lets me use coordinates in a range of local map datums and convert them to Lat/Long without me having to incorporate the whole of CGAL?
