• error message "cannot load the main class.

  I ran windows update yesterday and installed the recommended updates, restarted my laptop today the error message "Unable to load the main class" appears in a box and I couldn't do anything until I had closed this box, after the loading of firefox it displays a message not responding, then a bar indicating that plugin adobe did not start successfully so I clicked to reload page Then, I rebooted my laptop to see if this solves the problem, but the same error message appeared and firefox have responded in the same way, someone has an idea how I can fix this problem?  I run anti-virus software and malware from comodo and my OS is windows vista 32. I also downloaded an update for adobe flash yesterday but the problem has not produced until after I had done the updates of windows.  Thank you

  Hello Fiona,

  Thank you for your response.

  You are facing this problem might because of Java program on your computer.

  I suggest you perform the clean boot and check the status of the issue, which will help you identify the problem.

  Keep the computer in a clean boot and check the status of the issue. If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem. Continue with the remaining steps to pin-point on the third party service. After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

  How to perform a clean boot for a problem in Windows Vista, Windows 7 or Windows 8.

  Note: please go through the section:How to reset the computer to start as usual after a clean boot troubleshooting section of Kb to start the computer to a normal startup after you fix the problem.

• 30.0 Firefox is so slow since updated. IE & Chrome not having problems loading pages, showing the blank pages, need two or more tests to open Web pages.

  30.0 Firefox is so slow since updated. IE & Chrome not having problems loading pages, showing the blank pages, need two or more tests to open Web pages. It seems to have something to do with the Visual data on the pages. My MSN homepage gets old and dies every time I open the page after the re-opening and closing of firefox. It takes forever! What is a memory drain? Each open page in a new session of firefox suffer the same fate.

  Start Firefox in Safe Mode {web link}
  While you are in safe mode;
  Press < Alt > or < F10 > to display the toolbar.
  Followed;

  Windows; Tools > Options
  Linux; Edit > Preferences
  Mac; name of the application > Preferences

  Then Advanced > General.
  Find and stop using hardware acceleration.

  Dig safe web sites and see if there is still a problem. Then restart.

• How to show the main screen (home screen of blackberry)

  Hi guys,.

  I need to know how to show the main screen (home screen of the blackberry), even if it's in any screen (like saying "Calculator" etc)...

  This must be done by programming... is there a solution for this?

  Thanks in advance,

  I also had. This is to disconnect incoming call and display the main screen (home screen of the blackberry).

  EventInjector.invokeEvent (new EventInjector.KeyCodeEvent (EventInjector.KeyCodeEvent.KEY_DOWN, (char) Keypad.KEY_END, 0, 100));
  EventInjector.invokeEvent (new EventInjector.KeyCodeEvent (EventInjector.KeyCodeEvent.KEY_UP, (char) Keypad.KEY_END, 0, 100));

• "Could not find the main class" Java error on Windows 7, but not Windows XP

  Hi all

  It's the first app I try to package and virtualize with ThinApp.

  It is an old business application that usually runs on Windows XP SP3 x 86.

  The. MSI that I generated with Thinapp works very well when it is installed on a Windows XP SP3 x 86.

  However, our main goal to use Thinapp is to install on a Windows 7 SP1 x 64.

  But in doing so, the application triggers a Java Virtual Machine Launcher error message saying: "could not find the main class. Program will exit. »

  I thought that it was because the app includes a 1.4.2 JVM and that my XP has not any JVM pre-installed, but the main image on my W7 has a 1.7 JVM. But even after I uninstalled the 1.7 and installed JVM 1.4.2 on the W7 machine, I kept getting the error message so I guess that it is not bound.

  Y at - it an option that I missed during my MSI generation so that it can run on a Windows 7 x 64?

  Thank you all for your help.

  D.

  With the help of Lachi, we found that the app natively works on W7, no need for ThinApp it if the goal is just to make it work on W7, from a XP world.

  The only change we had to make (and the error was the same ThinApp-ed, which is what I originally shared) is that the application should work with Windows 7 in "classic" mode "of the screen (without Aero and the menu start XP-style). This is because the application runs an old integrated version of Java (1.4) and it makes the system calls seeking specific .dll to display, which are not accessible by default if Aero is enabled.

  Generally, you should leave a tool (e.g., Netbeans, Ant) create the manifest because they know how to do it properly.

• Access the main object of a SWF file in memory

  Hey.
  
  I'm trying to access the main object of a SWF file in memory. Consider the following code:
  
  package test {}
  import flash.display.Sprite;
  import flash.utils.ByteArray;
  
  SerializableAttribute public class Main extends Sprite {}
  public void Main (): void {}
  var b:ByteArray = new ByteArray();
  b.writeObject (this); This main object is what I'm trying to access
  }
  }
  }
  
  However, when I do a trace (b.length), the value I get does not match the length of the actual SWF file, then perhaps that there is another way.
  
  I am trying to achieve the same type of content that you would get if you load an external SWF using loadBytes, unless I want to access the principal object of SWF (running in memory) in this way.
  
  I have this even possible?
  
  Thank you.

  Hey.

  Well, I never knew a solution to it (if it is still possible to what I asked). However, I believe that I've implemented a workaround solution that should be enough for my needs. Perhaps it may help someone else too:

  Although I can not (seem to) get the SWF running access itself to memory, I can load another copy of itself. When I tested the copy loaded (in memory) and compared with the content of the file on the disk, using a hex editor, content match!

  This allows me to do things like control totals and which do not. An implementation is to use this technique to guard against the 'cache-hacking' of sovereign wealth funds.

• The main class and the class structure of game

  Hello.

  I m doing a game and now I wonder if it s handy to have a class named hand for my game.

  I thought I'd have a Preloader, Console and play classes.

  Now I Don t know.

  Maybe better to have a main class that loads including a preloader that loads the Console that it s loads of game.

  That s the best way to make an application of game? I m talking best practices.

  And why if so there must be a main class that extends Sprite?

  Thank you

  What is in a name?  It calls for what you want.

  for the best practices in the design of the class, google: models of object-oriented design.   It is a mature topic with lots of available information.

  and your document class must extend sprite or movieclip classes because your fla document has a timeline (with one or more images).

• Photosmart D7560 do not print envelopes-&gt; load paper into the main tray

  My photosmart D7560 h will not print envelopes, after having moved the envelope position for printing, the message "loading the paper in the main tray is displayed.  It prints correctly the data of envelope on a sheet of paper 8.5 x 11.  The Setup is for a #10 envelope.  Envelopes are self-sealing.  I tried to crease the edge better but that did not help.  I tried a non-self seal (who had a top letterhead so I couldn't use it for this shipment) and he worked.  Is it possible to do self seal envelopes work in this printer?

  You have the flap folded inside the envelope, so that it does not stick?
