• How can I sort an array so that certain file extensions sort to the top?

  - by rarbox

  I have an array containing a list of files. I want to sort it in a way that it will let me have .txt files in the beginning of the array and the rest of files after that. This is what I'm doing now, which works fine. @files = (grep(/\.txt$/,@files),grep(!/\.txt$/,@files)); Is there a better way to do it though?

• asp:upload postedfile lost during postback

  - by Neil

  I am using an asp:upload control to upload an image and am using the postedfile property to insert the path to the database. In my form I have a dropdown with autopostback=true where the user can select a topic to populate a checkbox list of categories. During that postback, the postedfile value is being lost and after a little research I have discovered that the posted file value is not maintained in viewstate for security reasons. Has anybody else found out how to get around this?

• How to use the Bass library to convert audio to another format (using C#)

  - by Siemsen

  Good day everyone and happy holidays. I'm trying to create a "simple" program that allows me to create a list of video files (Youtube video's to be precise) that are then run through by my program and converted any given format to pure MP3 audio. For this purpose I'm trying to use the BASS.dll and well it isn't going so well. I was wondering if anyone has used BASS to convert from one audio format to another? Or is there another library better suited for this?

• CVS branch name from tag name

  - by Jamie

  I have a number of modules in CVS with different tags. How would I go about getting the name of the branch these tagged files exist on? I've tried checking out a file from the module using cvs co -r TAG and then doing cvs log but it appears to give me a list of all of the branches that the file exists on, rather than just a single branch name. Also this needs to be an automated process, so I can't use web based tools like viewvc to gather this info.

• Parallel Task Library WaitAny Design

  - by colithium

  I've just begun to explore the PTL and have a design question. My Scenario: I have a list of URLs that each refer to an image. I want each image to be downloaded in parallel. As soon as at least one image is downloaded, I want to execute a method that does something with the downloaded image. That method should NOT be parallelized -- it should be serial. I think the following will work but I'm not sure if this is the right way to do it. Because I have separate classes for collecting the images and for doing "something" with the collected images, I end up passing around an array of Tasks which seems wrong since it exposes the inner workings of how images are retrieved. But I don't know a way around it. In reality there is more to both of these methods but that's not important for this. Just know that they really shouldn't be lumped into one large method that both retrieves and does something with the image. Task<Image>[] downloadTasks = collector.RetrieveImages(listOfURLs); for (int i = 0; i < listOfURLs.Count; i++) { //Wait for any of the remaining downloads to complete int completedIndex = Task<Image>.WaitAny(downloadTasks); Image completedImage = downloadTasks[completedIndex].Result; //Now do something with the image (this "something" must happen serially) } /////////////////////////////////////////////////// public Task<Image>[] RetrieveImages(List<string> urls) { Task<Image>[] tasks = new Task<Image>[urls.Count]; int index = 0; foreach (string url in urls) { string lambdaVar = url; //Required... Bleh tasks[index] = Task<Image>.Factory.StartNew(() => { using (WebClient client = new WebClient()) { //TODO: Replace with live image locations string fileName = String.Format("{0}.png", i); client.DownloadFile(lambdaVar, Path.Combine(Application.StartupPath, fileName)); } return Image.FromFile(Path.Combine(Application.StartupPath, fileName)); }, TaskCreationOptions.LongRunning | TaskCreationOptions.AttachedToParent); index++; } return tasks; }

• Summary of changes for each API level?

  - by MisterSquonk

  As the title says, are there any sources (web pages etc) of summarised changes at each API level? I have an app which I've put out to a small group of beta testers and I already fell foul of Environment.getExternalFilesDir(), which I hadn't noticed was introduced in API Level 8, when a couple of the guys tried it on Android v2.1 devices. The majority of my code should be pretty generic but it would be useful if I could find a condensed/summarised list/table or similar that I can quickly glance over.

  I've used Java for some time and I keep hearing about interfaces such as Cloneable, Iterable and other X-ables. I was wondering if there is a list somewhere of all of these and more importantly - which ones do you regularly use day-to-day? For example, I've read that Cloneable is considered badly written and isn't widely used.
