  • Rewriting simple C# nested class

    - by Daniel
    What would be an elegant way to implement the functionality of this nested class in F#? private class Aliaser { private int _count; internal Aliaser() { } internal string GetNextAlias() { return "t" + (_count++).ToString(); } } This was my first attempt, but it feels like there should be a sexy one-liner for this: let aliases = (Seq.initInfinite (sprintf "t%d")).GetEnumerator() let getNextAlias() = aliases.MoveNext() |> ignore aliases.Current

  • IE dynamic image caching issue?

    - by rdevitt
    I have an html page that is loading multiple iframes into which are embedded dynamic images created from a Tomcat server page (.jsp). This works as expected from Chrome and Firefox, but for some reason IE displays all of the images the same (as the first image). I've created an example: http://coupondiscounts.com/dev/jsImageTest.html jsImageTest.html -- This page simply loads 6 instances of the testImageFrame.html page in separate iframes one-at-a-time, using Javascript. testImageFrame.html -- This is the page loaded in all the iframes. It contains only a JavaScript block that writes out the current time and an img tag. The img is dynamically generated by a .jsp page on a different server. It should be a white box on a black background. In the box are the current time (from the Tomcat server using Java) and a randomly created double between 0 & 1. What happens (in IE): The page almost instantly loads four identical iframes. Depending on the speed of your machine, the JavaScript times may vary by a second or two. The images' times will all be the same as will be the random number. This holds true even for the last two iframes which are loaded 5 and 10 seconds after the others (using JavaScript setTimeout()). What should happen (as it does in Chrome and FF): The page loads the same 4 iframes, but the random numbers in the images will be different. The times in the images occasionally span a second as well. Anyone have a clue as to what's going on here? Is IE doing some strange caching? The image header has "no-cache," "no-store" and all that. I've tried it on IE6 and 7. You can use the "Next" button to create another iframe. In IE, the images are always the same. Notes: I don't really need iframes, just the images, but if I only use img tags, the problem appears in Chrome and FF as well. I also don't really need to load these iframes dynamically, I was just trying to abstract the issue further and allow a delayed load for the latter 2 images.

  • On Android, app jumps back to default Page on orientation change

    - by SteAp
    I tested my Xamarin.Forms app on iOS and Android and found this difference when I change the orientation of the mobile device: On iOS, the app keeps the current page On Android, the app seems to restart using the default page (or probably pop all pages except the first one). Since I've never seen this behavior in another Android app, I'd like to disable it. Moreover, I don't think that this behavior is Android default. Which property do I need to set the make the Android target behave as the iOS target?

  • Copying subversion commit messages

    - by Falcor
    I know this isn't the BEST practice, but every once in a while when I'm merging up a huge batch up changes with the trunk (and I know my branch is current), I will simply delete the contents of the trunk and then copy the contents of my branch up, so that I don't have to deal with resolving conflicts for an hour. The problem is that I seem to lose the entire history of commit messages for each file. My branch still has the correct history of commit messages... how can I merge them up?

  • Pasting non-text data into browser-based apps

    - by John
    Imagine I want a user to be able to copy-paste a selection of pixels from MSPaint into a browser-based app. Is this possible using JavaScript in any current browsers? Will it become possible in HTML5? If not, is it feasible using something like Flex/Silverlight, or is it simply not possible at this time, and you'd have to save a file and manually upload it?
