How do I get the number of byte already downloaded?

I put an embedded mp3 on my website and want to keep it hidden until the whole file has been transfered to the user�s computer. Is there any way of monitoring the download/preload/cache status in Java?
Gratefully waiting for any help...

I put this code on my page:
<object classid="clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA" height="20" width="150">
<param name="controls" value="controlpanel">
<param name="autostart" value="false">
<param name="src" value="audio/nameoffile.mp3">
<embed height="20" pluginspage="http://www.real.com/player" src="audio/nameoffile.mp3" type="audio/x-pn-realaudio-plugin" width="150" autostart="false" controls="controlpanel">
</object>
When a user with a slow connection opens the page and presses the play button he will only get a few seconds of audio, as the file has a size of 0.9 Mb. To prevent confusion I would like to hide the controlpanel until the whole file or a major part of it has been cached; I know how to hide the file and make it appear, but I don�t know if Java is able to find out how many bytes have already been cached...
Thank you for any help.

How to get the number of bytes at TCP port

Hi all,
How to get the number of bytes to read at the TCp port...as someone had suggested in some forum we do read the number of bytes first and then pass this...
but we get a problem when we have FF data in this...because then it sends 2 FF data...and cause of this we skip the last data...is there any solution for the same?

Hi
In LabVIEW you don't have the same property as in serail port.
You havn't "Byte at TCPIP port".
if you developp a protocol, one soltion, is to send the size to read.

How do you limit the number of emails that download in ios7?

How do you limit the number of emails that download in iOS7? In previous versions, I was able to limit (i.e. 50/100/ etc), the number that would download to my phone at any given time - other than new emails. Past/old emails would only be reloaded if I deleted newer ones or I requested more be loaded.

Now solved:

How to get the number of bytes at ethernt port using tcp/ip?

I have data with variable sizes.I am getting the data from another sytem using software C.
How can I get the exact number of bytes coming at the port before using the read command so that the no. of bytes at port has to be given as the input to the tcp read vi?

So may responses saying your question is wrong..... typical of this site, and no decent answer after 5 years !
The answer I have used is to use a call library function:
short int ioctlsocket(unsigned long socket, unsigned long fionread, unsigned long *len);
where fionread is a windows defined constant = 4004667F
The socket can be obtained from using the TCP Get RAW NET OBJECT.vi which comes with Labview (even as far back as version 7).
Good luck.
A protocol requiring such a hack is IMHO very poorly designed. You should always have some way on the wire to determine the data stream size. If the data is fixed size that would be inherent to the protocol, if it's variable sized there should be a fixed size header or a known message termination indication that can be used to determine how to read the rest of the message.
As a side node, I do consider the existence of VISA Bytes at Serial Port a big error, and that is most likely where this question originally came from. Use of "bytes at port" to decode a protocol will ALWAYS lead to protocol errors sooner or later, and code that is unneccessarily complicated to force the routine to deal with the asynchonous reading of the "bytes at port" into the protocol decoding.
If a protocol can't be decoded with fixed size reads, fixed size reads with following variable size reads determined from information in the header, or a specific message termination indication, then it is very badly flawed.

How can I get the number of rows in my sql result, without a loop?

Hello,
I've a problem, I would like to get the number of rows in my sql result without make a loop like :
while (rs.next()){
int number = rs.getRow();
Is there any method to do this, on the first element?
Thx, STeF

If you want to count how many rows are in result set, I dont think you can, but you could always run a count statement for that sql
say your sql is
select field1, field2, field3
from table1, table2
where field4=field5 ......
then you can count the rows this statement returns by
select count(*) from
(say your sql is
select field1, field2, field3
from table1, table2
where field4=field5 ......)
This way you will get the count for just that sql

How can I get the number of computers that a specific user had add to domain?

Greetings
In Win Srv 2K8 I know how to increase\decrease the total number of computers that any user can add to domain.
(http://support.microsoft.com/kb/243327/en-us)
but there is any way to get the number of computer accounts that a user had add?
thank you in advance

Hi,
Regarding your request, maybe we could use the 'ms-DS-CreatorSID' attribute to verify the computer number that a specific has joined to the domain. Please understand that for a
computer account created by domain users, the account has 'ms-DS-CreatorSID' attribute to indicate the creator user. When a user adds a computer to the domain, a process enumerates the 'ms-DS-CreatorSID' attribute on every computer account in the domain and
calculates if the sum exceeds the current quota for that user.
The 'ms-DS-CreatorSID' and 'ms-DS-MachineAccountQuota' with default value 10 are also available in Windows Server 2008 AD DS.
Note: The 'ms-DS-CreatorSID' attribute will be unset in the computer account that is pre-created in Active Directory Users and Computers MMC or joined by domain administrators.
Auditing on the computers container should work for collecting information of joining computer into the domain.
For details, please refer to the following similar thread.

Hi,
   You can try this:
* Let's say the table's datasource is a node called Table and it has two attributes first & second.
* You want to check if any of these attributes has been changed by the user or not. If they have been
* changed then you want to do some validations against them.
int sizeOfTable = wdContext.nodeTable().size();
for(int i = 0; i < sizeOfTable; i++){
     IPrivate<view name>.ITableElement ele = wdContext.nodeTable().getTableElementAt(i);
     if(ele.isChangedByClient(ITableElement.<attribute name>)){
        //value has been changed, do some validation. You can get the row index using ele.index().

How do I get the number back?

Okay, so last night I attempted to update my iPhone 4 to the iOS 7 software and it said it had to be restored so I did. But I forgot to back up some of my contacts first and I lost two contacts. One of which was my girlfriend's. I know that last part wasn't important but anyway. How can I get her number back? And when I tried to text her friend's number, I got an error message saying "Error invalid number. Please resend using a valid 10 digit number or shorter code". Why am I getting that error message??

I was having the same problem and here is how I fixed it.
I have fixed this problem on my iphone.
1. Delete all record of the problem number that will not except text messages.
Including contact, favorites, call log, text log...
2. send a text message to the phone number manually make sure to include the area code, no 1 needed.
3. click the sms button on your home screen, then select the number you just sent the message to and create a new contact from there.

How do you calculate the number of bytes in a hexidecimal array?

04h + 12h + 4Eh + 20h = 84h
Thanks

Hi,
I'm not sure if you want to count the bytes or sum the array. But here's an example of both:

Downloading (using iOS or computer) past purchases from the App Store, iBookstore, and iTunes Store - http://support.apple.com/kb/ht2519 - enabled with iTunes 10.3 and newer; not all media formats are available in all countries (see: iTunes in the Cloud and iTunes Match Availability by Country - http://support.apple.com/kb/HT5085); apps, books (not audiobooks), music, t.v. shows, and movies (some - not all studios have permitted this). Downloading previously purchased movies and TV shows requires iTunes 10.6 or later. Discontinued items not available. For items not included in the iCloud list (e.g., ringtones, audiobooks), or locations or computer systems where iCloud is not (yet?) available, you only get one download per fee paid. Apple notes it is your responsibility to back up your purchases.
Select the iTunes Store on the left side of iTunes.
Click on Purchased on the right side under Quick Links.
You can re-download your available previous purchases.

HT201269 My PC crashed. iTunes was on it and now all files are gone. All music does exist on iPad. How do I get the music that had been downloaded from iTunes and copied from my CDs onto new PC from iPad. Would rather not use cloud.

PC crashed. iTunes was on it and now all files are gone. All music both purchased and copied from CDs is on iPad. How do I get the music back onto the PC without using the cloud. Afraid if sync will wipe all music from iPad.

You would need to download iTunes on comp and download purchases again (you don't have to pay again) and upload your CDs again IF you sync your iPad to your computer it will erase everything

How do I get the number of channels available in DIAdem using VBScript?

I want to know the last number of the available channels in DIAdem-DATA using VBScript. If there are not enough channels, I'll allocate new ones using ChnAlloc.
For the first run of the script, I do know there're 60 channels, but in a second run I might have created the additional channels already (if the script didn't fail) and I don't want to do the allocation a second time. So I need to know the number of the last channel. Unfortunatly I didn't find any function in the help providing this number.
Thanks,
Carsten

Hi Carsten,
I have a few thoughts for you plus some useful code. Bear in mind that you can change the number of static DIAdem channels (by default 60 of length 8192) as well as the number of available dynamic channels (by default 1000) to whatever you want. These memory matrix settings get stored in your Desktop.DDD file (DIAdem's ini file), so that each time you launch DIAdem it will create the channels according to your specifications. The maximum number of channels of all types that DIAdem can have is 65536 (2^16).
Secondly, don't forget that you can address channels by name or by number. If the channels are named distinctly, addressing channels by name is the most reliable method. If you use ChnAlloc() to allocate new channels, and you want to address those new channels by channel number, you MUST use CNo() immediately after creating the new channel in order to find out that channel's number. It will not always be the next available channel number, because the next available channel may not be long enough. ChnAlloc() will latch on to an existing channel if it can find one long enough, and it will create new channels only if it finds none of the existing channels suitable.
In the VBScript I attached to this email you will find all the DIAdem variables which contain information about the maximum available channels and the maximum length of each channel (not its currently set length). Note that DIAdem's data matrix is divided into 8 submatrices, each with 2 GBytes of addressable memory (2^31 Bytes). Each submatrix can have multiple static channels assigned to it. DIAdem's dynamic channels come first from DIAdem's application RAM (Windows allocates no more than 2 GBytes per application) then from the Windows swap file for its virtual memory
Now, in addition to the variables which tell you the maximum possible channel count and lengths, another very useful variable is "GlobUsedChn", which returns the highest channel number currently filled with some amount of data.
Ask if you have additional questions,
Brad Turpin
