  c# c++ wpf memory fragmentation
  I’ve got what I assume is a memory fragmentation issue.We’ve recently ported our WinForms application to a WPF application. There’s some image processing that this application does, and this processing always worked in the WinForms version of the app. We go to WPF, and the processing dies. Debugging into the library has the death at random spots, but always with an array that’s nulled, ie, allocation failed.The processing itself is done in a C++ library called by a p/invoke and is fairly memo

  c++ memory heap detect fragmentation
  I’m writing a qt-based c++ application and i need to be able to detect memory fragmentation in order to check if the current system can actually sustain the memory load: the program load a big image (15/21 megapixels are the norm) in memory and then perform some filtering on it (w/ sparse matrices). For instance, i’m having memory fragmentation problem in Windows and VMMap has been very helpful in this: the problem was some DLLs (Wacom tablet “wintab32.dll” and the UltraMon app) doesn’t get relo

  android service activity heap fragmentation
  I have an Android app (activity) which also has a corresponding service. The service is started by the activity and is supposed to run continuously even when the activity is stopped. When the activity is started again it can bind to the service and query it.Sometimes the activity gets destroyed and created by the OS. This should not affect things, the activity should just be re-created and be able to bind to the service again. This basically works.However…I have found that both the Dalvik VM h

  linux redhat fragmentation
  Our application runs on Red Hat Linux 8.0 3.2-7, Linux kernel version 2.4.32. We’ve found that the OS does not know how to handle fragmented packets. When receiving a large amount of fragmented packets, the application running on the OS, crashes due to out-of-memory. Does anyone know of a solution? or can refer me to a Linux version that resolves this issue? Thank you.

  android debugging exception fragmentation
  I have an android app that is getting a null pointer exception on some phones (all 2.3.x) but not on my phone (also 2.3.x) or on any of the simulators. The particular exception doesn’t seem give any indication that it is occuring within my code, so I assume I am making an call that some version of the same API thing is incorrect? I’m not sure what to make of it.Here is the error log from logcat:01-23 14:25:33.614: D/AndroidRuntime(25648): Shutting down VM 01-23 14:25:33.614: W/dalvikvm(25648): t

  Consider registering entrance of new members in a Dictionary and the time of entrance:Dictionary<string, DateTime> members = new Dictionary<string, DateTime>(); members.Add(“Bob”, DateTimeNow); Thread.Sleep(1000); members.Add(“Joe”, DateTimeNow); Thread.Sleep(1000); members.Add(“Susan”, DateTimeNow); Thread.Sleep(1000); // Now Joe exits members.Remove(“Joe”); // Then Mike enters members.Add(“Mike”, DateTimeNow);Now the question is where’s Mike location in Dictionary. Is he added to t
