How do I know how many bytes it has read so far ?
Like in a FileInputStream.read(byte [] b) method. How do I know how many bytes have been read into b so far ? Thanks!
You can't directly as the method block, however it return the number of bytes that could be read. To achieve what you want I would create a wrapper class that would override read(byte[] b) and process it byte by byte with:
int size = b.length;
for(int i = 0; i < length; i++)
int r = wrapped.read();
if( r != -1 )
b[i] = (byte)r;
readSoFar++;

How can I know how many processors do I need for a new SQL Server machine?
My company intend to buy a new server and will dedicate that for SQL Server which will serve an in-house developed application.
How can we know how many processors are enough to buy?
I know that each SQL Server edition and version has it's different limitation of the number of processors it can support, for example SQL Server 2012 Standard Edition can support up to 4 sockets or 16 cores per SQL Server Instance, but this does not mean
that I have to buy 4 physical CPUs. two could be enough. how can I know?How can we know how many processors are enough to buy?

This is off topic question how can we answer it. We even dont have any knowledge about your application.
Please speak to licensing specialist about servers and cores below link will give you more information.

How I can know if a user has the permission to read a file or not ?
Hello,
I have other question :
How I can know if a user has the permission to read a file or not ?
Smaine
ThanK'sI don't think common operating systems have an easy way to do that check.
If you have a limited number of files, implement access control yourself, instead of using operating system permissions. E.g. write a configuration file that contains:
# Syntax: "filename": "list of users who can access that file"
somefile.txt: fred, alice, bob
somedir/anotherfile.txt: bob, joe
Read in the configuration file and check against it when a file is being requested. -

How do i know if my apple has a virus?
How do I know if my apple has a virus? How do I check?
What makes you ask? Are you having a problem that you believe is due to some kind of malware? If so, what is that problem? Describe the symptoms in detail... they're probably not due to malware, so knowing what is going on is important.
If you're just curious about protecting yourself against malware, see my Mac Malware Guide.

How do I know if the program has been downloaded to another computer or not?
How do I know if the program has been downloaded to another computer or not? Also how do I know if it is the educational version or not?
What exactly? Your questions don't make much sense since you failed to provide an explanation what problem you actually have, what program you actually mean and so on. That aside, edu versions are technically not different from the normal programs, just their licensing is different.

Since you are having an issue with syncing to a different apple id. You may want to make sure you are signing in with the correct apple id.

How do I know if Mountain Lion has installed properly?
How do I know if Mountain Lion has installed properly?
I can only guess that the install process was interrupted, maybe after the files were extracted but before the install, maybe on the reboot?
If it was dome ot would say version 10.8. And you would have the reminder and notes apps as well, also an easy thing to check. -

Hi,
for Iphone tips page "see when a message was sent " , then how do I know that the message has been read? ThanksHi Bhavesh,
Please see my replies inline:

When I click on "Where did the error occur" -> "Adapter Engine", I do not have a choice of errors from the dropdown. I only see one option "*".
Is this right?

I see.
I've also managed to overcome this problem by selecting "Subscription Authorization" in the Alert Category Definition page, and entering SAP_XI_MONITOR as one of the roles.
After that, I am able to see a the alert category defined. By default it's already subscribed, because I'm using the same user - PISUPER.
I saw in another post that the option "Suppress Multiple Alerts of this Rule" should be left unchecked. I tried that, but I still do not see any alerts raised in ALRTDISP.
What did I miss?
Please help.
Thanks.
