Is there any way to identify the two classes are compiled by same vm

Is there any way to identify the two classes are compiled by same vm?
Thank's a lot.

I think this is the better forum than java compiler. The answer to the question you asked is no.
But that question is not the best way to address your problem.
If this were me, I'd use a tool like ASM (http://asm.objectweb.org/) to read in that file, and replace the getToday() method, with one like this
long getToday() {
return 20080101;
}and replace the class file with this new one. (keep the old one, they might be using a class loader that verifies class signatures or something)
(They said the code you are looking at could have been changed by you - so take the hint and change it back).
If they've ripped you off, this will restore justice much more cheaply and effectively than involving the lawyers. If they then sue you for breaching the license agreement, that would probably force them to disclose their underhand tactics.
OTOH, if you're lying to us about the purchase, and needing to pay for upgrades to fix the performance issue, and instead are trying to crack some trial software, then I hope they are using a custom class loader that checks the integrity of the classes.
If you are being ripped off, why are you not telling us the name of the company? I am not sure who is being ripped off here.

Is there any way to identify the particular socket connection is closed ?

Is there any way to identify the particular socket connection is closed or not ?
Any methods ???
How can the program knows the connection is lost or some thing ...
Is the socket throws some excpetions when there is no active connection ???
namanc

If you get an IOException when you try to use the socket, the connection was obviously closed.
The correct way for an application to know if the socket was closed is:
1) the server sends a message indicating that the socket should be closed
2) the client closes the socket itself

Is there any way to judge whether two streamings are casted by the same client?

Hello,
My app use two different streams to send video and audio from flash clients to the server.
So another client need to judge whether two streamings are casted by the same client or not.
Is there any way to do this?
For example, if it is possible to get ip address from netStream instance, it will be a solution.
Could anyone teach me this?
Thanks in advance!

Subtract Composite Mode
Subtract darkens all overlapping colors. Whites in the foreground image go black, while whites in the background image invert overlapping color values in the foreground image, creating a negative effect.
Blacks in the foreground image become transparent, while blacks in the background image are preserved.
Overlapping midrange color values are darkened based on the color of the background image. In areas where the background is lighter than the foreground, the background image is darkened. In areas where the background is darker than the foreground, the colors are inverted.
The order of two clips affected by the Subtract composite mode is important.
Difference Composite Mode
The Difference composite mode is similar to the Subtract composite mode, except that areas of the image that would be severely darkened by the Subtract composite mode are colored differently.
The order of two clips affected by the Difference composite mode does not matter.

Why does my mac have 100 gb of "back up" and 90 gb of "other" memory used up when I have hardly anything on it. Is there any way to identify what those things are that is consuming so much memory?

I have 25 gb of music. 20 gb of movies. 5 gb of pictures. 10 gb of apps. 102 gb of "back up. and 85 gb of "other. which leaves less than 70 gb open on my harddrive.. Why? What is that almost 200 gb of memory? How Do i pinpoint it? I use time machine and an external harddrive to back up my files so what is that? any answers or ideas?

Do not worry about the backups. They will be deleted automatically after a week, or if your HD gets too full. See #30 in Time Machine - Frequently Asked Questions.
The "other" stuff is just that -- all sorts of things that don't fall into the few categories listed. The operating system, system work files, plus lots of your stuff like documents, mail, etc. See Lion's Storage Display

Is there any way I can merge two accounts on my macbook?

I have two accounts on my macbook (version 10.6.8), one that i created when i got the laptop and one i created a few years after because i couldn't remember my old password(which i know now). Is there any way to merge the two accounts into one? (itunes, iphoto, apps, etc.)

Office for Mac or Office 365. I use it on my Mac and although not as polished or feature rich as the Windows version, serves my purpose perfectly. I also regularly switch between Windows at work and Mac editing the same document so cross-compatibility has been fine too: http://www.microsoft.com/uk/mac
You could always try Open Office which is free: http://www.openoffice.org/porting/mac/

I am trying to switch laptops with my mom, and successfully wiped mine and restored it, but now her password won't allow her into my computer, even though it says it's her account. Is there any way to bypass the password screen?

I am trying to switch laptops with my mom, and successfully wiped mine and restored it, but now the password that she used on her computer isn't working on this computer. Is there any logical reason why the two passwords would be different, if I restored her information from a Time Machine backup? Aditionally, Is there a way to bypass the password page on startup to make a password that my mom knows?

If Disk Warrior does not work you can try the following steps (but they may not work if the disk has a hardware error).
Get the disk (DVD or CD) that came with the system (since you have it listed as 10.6.8). If it is 10.7 or 10.8 use the Recovery partition to boot from or the USB installer if you have that option.
Insert the disk then power down
HOLDING the C key, power up to boot from the disc.
Get to Disk Utility
If Disk Utility will now show your hard drive, use DU to REPAIR the disk.
When it completes the Repair process successfully as indicated in DU, do a shut down. If Repair is not successful then an different course of action is indicated below.
Then HOLDING THE APPLE (or Command key depending on your keyboard) KEY AND THE OPTION KEY AND THE LETTER P AND R KEYS, continue hiolding them until you hear the chime tone for the THIRD time then release all four keys.
If REPAIR is not successful, use the Install disc as a boot and REINSTALL THE OS X OPERATING SYSTEM DO NOT ERASE THE DISK OR VOLUME FIRST. REPEAT DO NOT erase the disk or volume before trying to reinstall the OS X operating system. After re-installing the OS do a software update. Note that ERASING the disk is NOT required to do an OS re-install. This allows your existing data and application files to remain.
If that fails then you are down to the "bitter end" of erasing the volume and reinstalling the OS and then all the other software.
If erasing the Volume fails then your last hope is to completely erase the entire hard drive, repartion the disk and try a re-install.
If that fasils then you may have a defective hard disk.

Is there any way to control the volume on my Apple TV?

Here's the scenario: I have a small amplifier under my couch that controls the speakers connected to my Apple TV. When I use Airplay from my iPhone to listen to music, I'm able to control the volume right from the music App on my phone- this is perfect because I don't like to reach under the couch to change the volume. However, there are two scenarios when I cannot seem to adjust the volume anywhere except on the amp. These are:
First: Using Airplay while playing a video from my MacBook Pro to the Apple TV. In this case, the volume slider in iTunes suddenly has a little lock icon on it and is unadjustable. Is there any way to unlock the volume?
Second: When using the Apple TV directly to play any media- music or movies. The volume up and down buttons on the Apple TV don't control the volume. I'm forced to reach under the couch to adjust the volume- which happens quite frequently. Is there any way to control the output volume of the Apple TV?
The lack of volume control has been super disappointing. I've been a (multiple) airport express user for years so kind of expected Airplay to work the same for video- with the ability to control the volume from whatever device was transmitting. Can anyone help me?

Andrew- this is how I would expect things to work. However, when I use airplay from my iPhone to say, play a youtube video, the volume on the phone is suddenly rendered useless and I'm forced to adjust the amplifier. When I just play audio from the phone, the volume works.
It's the same on my macbook pro. If I mirror the screen, my computer's volume affects the speakers volume. However, if I am in itunes and play a movie and use airplay for that, I get a lock on the volume. Is this a setting somewhere?

Is there any way to disable the objects owned by a user?

Hai every body....My problem is..
I had created 60 users granting them connect and resource privileges in oracle(8.1.5.0.0).All of the users are working under their logins(users)...Every thing is going fine...But now i wanted to disable the objects owned by those users
(60 Users) for a period of 2 days,After that i wanted to enable them....Is there any way to disable the objects owned by them with out dropping the users?(The users should be able to work as prevoiusly on the new objects they will create after i disabled the objetcts owned by them previously)?

hi
if my understanding is right you want to disable the users for 2 days for any reason let say he is on holiday for 2 days then why dont u lock this user and submit the job for unlock after two days.

I have written a binary file with a specific header format in LABVIEW 8.6 and tried to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?

I can think of two possible stumbling blocks:
What are your 8.6 options for "byte order" and "prepend array or string size"?
Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

Is there any way to change the background colour in Photoshop Elements 8?.

Is there any way to change the background colour in Photoshop Elements 8? There are two options offered in General Preferences, Appearance Options - Dark Grey or Light Grey - but even the Light Grey is much darker than that in Photoshop CS2. I would like to make the background much lighter. All advice will be appreciated.

Thanks for your comments.
I have seen that the background can be changed in PSE7 by using a slider in Preferences- General; I don't understand why Adobe didn't keep that facility.

Is there any way to change the settings for the built in isight camera?

I'm sure someone else has probably already asked this, but is there any way to change the settings for the built in isight camera? The resolution is horrible.

Welcome to  Discussions, Prissymissysays
The last Apple-published resolution data I saw said that iSight's resolution is 640x480 VGA. I do not know of any way to change iSight's resolution, but that level is plenty of quality for my webcam needs.
The software you use to operate your iSight controls it, so specific answers will depend on what software you are using when you need more resolution. Check Help in that application to see if it can change iSight's resolution.
Some software, such as Apple's QuickTime 7 Pro allow you to change iSight's video quality and compression level with its QuickTime Player > Preferences > Recording > Quality: setting. You can add iGlasses software to manually override some iSight settings that are otherwise controlled automatically by the software using iSight. However, I do not think either of these options really changes iSight's resolution.
Check whether your iSight's lens cover has fingerprints or smudges on it. Then check iSight's image quality of your face in full sunlight about two feet from the lens. Best image quality requires more light than what most people would consider normal room lighting.
If you are still having problems, consider the applicable suggestions from How to Troubleshoot iSight.
If you need better resolution than iSight can deliver for some special imaging requirement such as close-up or high-accuracy images, you may need to consider using a different camera that better meets your special needs.

Is there any way to match the dock and USB to the iphone it goes with?

We have several iphones in our household. An iphone 3, two iphone 3S and two iphone 4S. Our teenage daughter keeps snatching everyone's charger and then claims innocence. Funny thing, everyone's chargers are all gone and she's the only one who has one left. We've never caught her red-handed, but we know without a doubt she's the little thief in the house. Is there any way to match the dock and USB to the iphone it goes with?

A charger is only connectors plastic and rubber you Can MAKE one yourself with wires so no memories

Is there any way to know the T-code from the screen?

Hi friemds,
it s a general question. but I found relavant for posting here.
I saw our group friens giving some T-codes for spro functions (eg: SNRO, M/06), bbut how to know the transaction from path. i.e. If I go to condition types screen, there I could not see any transaction. is there any way to know the T-code from the screen?

Hi,
Listed here are the various ways you can find the list of transaction codes and their usage:
Use transaction SE11 - ABAP Dictionary:
Fill in the Database table name and click the Display button.
- TSTC table will contain all the Tcodes and
- TSTCT table will contain all the Tcodes with Texts.
Once you entered the screen, click in Top Menu - Utilities - Table contents - Display
If you want to display all the transaction code (total - 57,048) you have to change the Fields: Maximum number of hits to 99999 (default 500).
or
Simply goto transaction SM01, although this tcode is to Lock/Unlock any transaction code, you can also view all the tcode available in the R/3 system from here.
or
Goto transaction SE93
There are two ways where you can find the list of transaction codes in SE93.
Method 1:
You must be familiar with the starting characters strings for each of the R/3 application modules.
Assuming you know that most Materials Management transaction codes start with MM.
In the Fields: Transaction code, type in MM* and press the function key F4
The list of transaction code starting with MM will be displayed.
Method 2:
On the Top Menu, click Utilities - Find - Execute and the first 500 transaction will be display.
If want to display all the tcodes, make sure you remembered to change the Fields: Maximum no. of hits right at the bottom of the screen.
I know a particular T Code and can enter and work on it. How do I know what is the menu path for that T Code?
Enter Search_SAP_Menu in the command box and when the pop box appears enter, the Tcode and it will give the nodes and menu path.
This is helpful only in case of SAP Menu not in case of SPRO - ie IMG.....
Reward if Helpful,
Regards,

Is there any way to filter the LCCS room console from the list of users?

I want to be able to hide the user that's logged into the room console from the list of users. Is there any way to identify that user?

Hi,
There is no standard way to hide users as such other than using anonymous presence. But the catch is, if you would set any property of change anything from dev console that publishes a message, then you will be noticed.
The user that logs into the room console is always the owner, may be your client app, you can hide based on your both permission level and name/userID by subclassing Roster. I am just throwing up ideas, but as such there is no standard method for this.
Whats your use case ? It's an interesting thought though and something we would think about on our side.
Hope this helps
Thanks
