I'm new to c#, and trying to learn by writing some simple apps to get familiar with the syntax and .NET library. The most recent miniproject I took on is a polar clock like the one found here. One of the problems I noticed early on was that the app would constantly "flicker", which really took away from the presentation, so I read onli...

It causes an out of memory exception. /// <summary> /// Rotates the specified img. /// </summary> /// <param name="img">The img.</param> /// <param name="rotationAngle">The rotation angle.</param> /// <returns></returns> public static Bitmap Rotate(Image img, float ro...
I am loading a bitmap from a resource like so: Bitmap mBackground = BitmapFactory.decodeResource(res,R.drawable.image); What I want to do is make some changes to the bitmap before It gets drawn to the main canvas in my draw method (As it would seem wasteful to repeat lots of drawing in my main loop when it isn't going to change). I a...
I ran some code last Friday before leaving work, and I'm here on Monday, and it stopped with an OutOfMemoryException. This entire process I estimate required making tens of billions of calculations, so it wasn't some small task. I don't even know how to begin fixing this. Any pointers? ...

Hi, I am writing a full database extract program in java. Database is Oracle, and it is huge. Some tables have ~260 million records. The program should create one file per table in a specific format, so using Oracle datapump etc is not an option. Also, some company security policies do not allow to write a PL/SQL procedure to create fil...
When exporting a lot of data to a string (csv format), I get a OutOfMemoryException. What's the best way to tackle this? The string is returned to a Flex Application. What I'd do is export the csv to the server disk and give back an url to Flex. Like this, I can flush the stream writing to the disk. Update: String is build with a Stri...
It might be a simple fix, but I can't for the life of me think of how to do this. I compute a bunch of StartDates and End Dates into a bunch of arrays of dates using this query: this.Reserved = unit.Reservations.Where(r => r.Active.HasValue && r.Active.Value).SelectMany(r => Utilities.DateRangeToArray(r.StartDate, r.EndDate)).ToArray();...
Hey I'm testing out Runtime.freeMemory() with this code: Runtime runtime = Runtime.getRuntime(); long freeMemory = runtime.freeMemory(); // This is some arbitary factor that should work <= 1 double factor = 0.8; int size = (int) (factor * freeMemory); byte[] testArray = new byte[size]; I'm creating a byte array of size close t...
I have a Java client - server application. The client is designed to run arbitrary user code. If the user code running on the client creates an OutOfMemoryError then the client ends up in an ugly state. Normally the client would be sending messages (via RMI) to the server until the code the client is running terminates and the client gra...
Hi, I have a program that sometimes throw OOME, I understand that there is a flag in the JVM options that I can set and whenever a certain Error/Exception appears (such as OOME) it calls a script I wrote. The script will give the user a notification and will call a the program with a different argument so it won't get OOME again. does ...

Hello, Is it possible to use the FromStream method of System.Drawing.Image without having to keep the stream open for the lifetime of the image? I have an application which loads a bunch of toolbar graphics from resource files, using a combination of Image.FromStream and Assembly.GetManifestResourceStream. The problem I'm having is wh...
Why is it that I'm getting an out of memory error? Thank you if (File.Exists(photoURI)) { FileStream fs = new FileStream(photoURI, FileMode.Open, FileAccess.Read); Image img = Image.FromStream(fs); fs.Close(); } ...
Hi folks, I am facing java.lang.OutOfMemoryError throwing from here : com.rsa.certj.cert.AttributeValueAssertion.clone Do you have any idea about that? ...
Hi all, when loading lots of objects, I get a OOM-Exception. After analyzing the heap with a profiler, I see that there's a lot of memory in org/hibernate/util/IdentityMap which references a LinkedHashMap containing thousands of Entrys. What are those objects used for? I'm really thankful for all kinds of information... ...
