  c# java runtime detect
  I program windows applications using Java and this builds a “.jar” file not an “.exe” file. When a client computer with no java runtime installed opens the “.jar” file, it runs as an archive with winrar. All I want to know is how to detect whether java runtime is installed or not on a computer using c# code in order to show a MessageBox telling user to install java runtime, or launches the “.jar” file using the java runtime if it’s installed.Thanks very much 🙂

  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

  I wanna send /data/anr/traces.txt if app ever crashed, but the question is how can I know my app crashed before.

  windows detect printscreen react
  I have a bit of a challenge.In an earlier version of our product, we had an error message window (last resort, unhandled exception) that showed the exception message, type, stack trace + various bits and pieces of information.This window was printscreen-friendly, in that if the user simply did a printscreen-capture, and emailed us the screenshot, we had almost everything we needed to start diagnosing the problem.However, the form was deemed too technical and “scary” for normal users, so it was t

  13.04 usb detect
  I’ve done some researching over the internet and this seems to be… I don’t know… a hardware problem? I can’t tell exactly. One thing I know for sure is that it happens to a lot people in Windows and they can’t solve it by tinkering with settings (duh, cause it’s happening outside of windows) but some people seem to be able to fix it by updating USB drivers, so…Here’s the problem… and it’s only intermittent; however it IS happening to me right now and I figured it was a great opportunity

  javascript jquery detect
  Hey folks! I’m working on a do-dad that can be embedded in a page like a youtube video. The particular effect I want needs jquery to work.I want to load jquery on the condition that something on the page hasn’t already added jquery. I though of testing if (typeof($)==’function’){…but that only works if jquery is loaded & running by the time the page gets to my script. Since best practices these days is to embed you scripts in the footer, my embed code probably will never see jquery mos

  javascript events highlight detect
  I’m writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I’m stuck. An example would be nytimes.com (when you’re reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I’m 16 and not much of a programmer, so that is definitely way out of my league.
