out-of-memory

问题 I've simplified things as much as possible. This is reading from a table that has around 3,000,000 rows. I want to create a Dictionary from some concatenated fields of the data. Here's the code that, in my opinion, should never, ever throw an Out Of Memory Exception: public int StupidFunction() { var context = GetContext(); int skip = 0; int take = 100000; var batch = context.VarsHG19.OrderBy(v => v.Id).Skip(skip).Take(take); while (batch.Any()) { batch.ToList(); skip += take; batch = context

问题 I have a layout which I'm adding ImageViews (about 13) to at run time using a single thread. When I load more than 7 or 8 images (970px x 970px, 270kb) the application crashes displaying an out of memory error. Now when I load the same image rather than choosing 13 different images it displays fine. And also when I reduce the size of the images (16px x 16px, 770bytes) it displays fine. So does anyone know what the max memory allowed when loading images? What is the best way to get around this

问题 In my activity I am creating a Bitmap of the width and height same as the device resolution (width and height ) what I am doing Bitmap mBitmap = Bitmap.createBitmap(screenWidth, screenHeight, Bitmap.Config.ARGB_8888); and screenWidth and screenHeight is screenHeight = displaymetrics.heightPixels; screenWidth = displaymetrics.widthPixels; Now if I make this bitmap I get my heap goes up to 19mb , which is not so good. So tell me 2 things 1. What is a good way of creating the bitmap with respect

问题 I have an application that saves User Information with Image into a data base. Admin can access the information those are already saved through a different form view.

How to resolve it? public class MyAlbImageAdapter extends BaseAdapter { public List<MyAlbum> _albumList=AppController.getInstance().getPrefManger()

问题 I have an interesting problem. I am using Ant which executes JUnit tests (test suite composed with 50 tests) via build.xml element. The problem is that I receive OutOfMemoryError. I have enlarged heap space using ANT_OPTS arguments but it did not help. When I execute the same test suite in Eclipse - everything is fine - memory is released thanks to GC. I think that this problem is related to Ant and its JUnit task. Maybe logging of the tests are the reason(but on the other hand I have

问题 Can anybody explain why this code throws OOME when I run it from Eclipse (Juno) but works fine when I run it from command line? I use -Xmx256M in both cases. static class Task implements Runnable { byte[] buf = new byte[150000000]; @Override public void run() { } } public static void main(String[] args) throws Exception { System.out.println(Runtime.getRuntime().maxMemory()); ExecutorService ex = Executors.newSingleThreadExecutor(); ex.submit(new Task()).get(); ex.submit(new Task()).get(); }

问题 I'm using RichTextBox to convert a string in RTF to plain text, using this piece of code: private string ConvertToText(string rtf) { if (string.IsNullOrWhiteSpace(rtf)) return string.Empty; if (!rtf.Contains("{\\rtf")) return rtf.Trim(); using (var helper = new System.Windows.Forms.RichTextBox()) { helper.Rtf = rtf; var plainText = helper.Text; if (string.IsNullOrWhiteSpace(plainText)) return string.Empty; return "<< Rule in Rich Text Format converted to Plain Text >>\n\n" + plainText + "\n\n

问题 I have written a code to allow the user to start and stop a feed from their webcam. I have used AForge.NET's NewFrameEventArgs to update a PictureBox with the new frame each time it changes. Everything works perfectly however whenever I start the feed, the RAM usage on my computer slowly goes up until an OutOfMemoryException occurs. Please could you help me find out how to clear or flush this somehow. When I get the exception, it occurs at the bottom of the code in ScaleImage: System.Drawing
