How can I read realtime data from a data socket using DIAdem

I am currently routing data from an instrument using LabView 7.1 to a data socket. I was trying to figure out how to access that data in real time in DIAdem through the data socket. Another option would be to use the downloaded LabView/DIAdem VI package, but I haven't figured out how to get that to work either, despite the forums here. I would prefer to access it through the data socket, if possible, as the amount of information being transferred is negligable (a string and a double).
Thank you,
Sinan Sutcu

You have to use one of the ScriptDAC blocks. In your case, as you would like to fetch data from a LabVIEW vi, choose the out of the driver input palette. Inside the configuration dialog you can generate a sample script, which is then copied to the windows clipboard. It contains a lot of function prototypes which will be automatically called later during the measurement.
Basically, the init functions are called during the start of the measurement - here you should connect to the activeX server, the deinit functions are called when stopping the measurement - disconnect from the server here.
Then there is the function SFD_Readchannel, which is called once for eych tact and each channel you configured. Here, you should exchange the data with your VI.
I am attatching an example I wrote to control a LabVIEW vi (doing a counter output operation)- that is why the data exchange works the other way around, but I hope it explains the principle.
Additionally I am adding documentation about the ScriptDAC driver interface.

How can i read pwm signals from a rc receiver using myrio??

Hello, i bound a transmitter (rc remote control) with a receiver which i connected it (the signal's pin) to the digital port on myrio. It showed me a boolean indicator, and it wasn't turning on the whole time even when i moved a cursor on the transmitter. When i put a time delay of 1sec in the code the results started to show true on some positions of the throtlle. Can anyone tell me how can i interpret those result to create signal conditioning and control some motors?? thank u all in advance

How can I read pdf files from LabVIEW with different versions of Acrobat reader?

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

How can I read text files from LAN if I only know the hostname?

I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
<p>1. How can I read text files from LAN if I only know the hostname, or IP address?
<p>2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.
(ex. how can I read the 120th line?)
<p>Please help!
<p>sorry for the bad english

I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
1. How can I read text files from LAN if I only know the hostname, or IP address?You need to know the URL of the file. You need to know the hostname, port, protocl and relative path.
The hostname is server, not file.
2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.Use the seek() to get to a random byte.
(ex. how can I read the 120th line?)The only way to find the 120th line is to read the first 120 lines. You can use other file formats to find the 120th line without reading the whole file but to need to be able to detremine where the 120th line is

How can we read some bytes from every line of the file

How can we read some bytes from the every line of the file moving on to the next line
without using the read line

Actualiy readLine() takes more execution time
for reading a part of line if we can do so without
readLine() we can save some time...Well, if you knew, beforehand, the length of each line, you could use RandomAccessFile and its seek method, but, since you don't, you would have to read the rest of the line character-by-character, checking to see if it is a newline, in order to place the "cursor" at the beginning of the next line in order to read the next few characters you want.
So, as you can see, you will need to read the entire line anyway (and if you do it yourself you also have to do the checking yourself considering all three possible end-of-line sequences), so you just as well use readLine().
Some people may suggest Scanner and it's nextLine() method, but that also needs to read the rest of line (as evidenced by the fact that it returns it), so that is no different than the readLine() (or read it yourself) solution.

if (!rs.next())
System.out.println("Empty Result Set");
bl = rs.getBlob("bl");
if (bl == null) {
System.out.println("Null Blob");
return;
InputStream is = bl.getBinaryStream();
int imageLength = (int) bl.length();
System.out.println(imageLength);
System.out.println(bl.length());
byte[] imageData = new byte [imageLength];
is.read(imageData, 0, imageLength);

How can I read books purchased from iBooks on my Mac?

I'm completely new to the whole Apple world and have ran across this issue. How can I read books, that I've purchased through iBooks on my iPad or iPhone, on my Mac? Surely this is possible, but I just can figure out how Apple intends for us to do this.
If someone could please help me out with this information I would appreciate it.

Or I can just purchase them from a competitor such as Kindle and read them on my Mac
Sure seems short sighted on Apple's part not to have this functionality. This will drive my purchasing decisions to Kindle.
I'm sure that there has been plenty of negative feedback already directed to Apple for this decision. Does anyone know whether or not they have listened and if they have any plans to correct this issue?

How can I read epub ebooks from public libraries?

Hallo,
how can I read ebooks in epub format I have downloaded from public library on the iPad? They are valid for 7 days, I can open them with Adobe Digital Edition.
I get them into iTunes, I even get them on the iPad. But I am getting an error message when I try to open them with iBook.
If iBook can't read them, is there another app I could use?
Hopefully somebody could help.
Thanks, foxbetti

You've answered your own question. Basically, you use Adobe Digital Editions (or Sony Reader Library) software which is keyed with your valid Adobe ID to manage content downloaded to an "authorized" computer for transfer to compatible "authorized" mobile devices. However, as far as I know at this time, the iPad is not yet supported by either application.
Here is what Adobe says:
Some digital publications that you purchase online or check out from a library may contain digital rights management (DRM) protection that restricts the items from being shared with others. In the past, this could limit the ability to read your items on additional computers owned by you. It could even prevent you from moving your items when you bought a new computer.
Digital Editions helps ensure that your eBooks and other digital publications are not "locked" on one computer — they are assigned to you through your Adobe ID. Digital Editions also adds support for the next generation of mobile devices.
Adobe membership is free and registration only takes a minute. As a member, you have access to trial downloads, hundreds of free product extensions, and special community areas. Your membership also allows you to view and manage your activity in the Adobe Worldwide Store.
An Adobe ID is a free and a nonintrusive way of identifying users — you need only provide a name, country, and e-mail address. You can create your Adobe ID when prompted within Digital Editions as you authorize your computer, or go directly to the Adobe.com membership site.
Once you authorize your computer with Digital Editions, the application looks for eBooks already on the computer and converts copies of the items to a new named account license. You can then transfer those eBooks to other computers. If you have eBooks on multiple computers, you need to authorize each one with Digital Editions prior to transferring eBooks between them.
Important: Digital Editions converts eBooks that have been purchased with Acrobat, Reader, or earlier versions of Digital Editions. However, items licensed using Easy Activation can only be converted on the same computer with which they were originally purchased. If you are contemplating buying a new computer, changing the hard drive, or upgrading the operating system, consider keeping your old computer intact unless you bought all of your books with Acrobat or Reader using Named Activation.
Digital Editions detects borrowed eBooks and displays them in the Borrowed bookshelf. However, if you borrowed an eBook with Acrobat or Reader, you cannot transfer that book to another computer. You must return the library item and then borrow the item again using the current version of Digital Editions.
Digital Editions does not require you to authorize your computer with an Adobe ID. This option is necessary to address concerns about some users' needs for privacy (for example, library patrons and minors). However with this option, protected items that you have already downloaded or will download later are tied to that particular computer and are not readable on other computers or devices. They also can't be restored from backup if the operating system is reinstalled.
When you first launch Digital Editions, you are prompted to authorize your computer. You can decline, in which case your digital content will belong to the computer, not a named user account. Subsequently, you will be prompted to authorize your computer whenever you purchase an eBook, although the prompt dialog box provides a"“Don’t ask me again" checkbox.
Digital Editions has an “Authorize this computer” menu item that you can use after initial installation.
Important: If you authorize your computer with an Adobe ID, then it will always be associated with that Adobe ID. If you do not, the account is "anonymous". If you "anonymously" activate two computers, then there are two separate anonymous accounts, which cannot be merged. Thus, the eBooks on one computer can be upgraded to "belong" to a specific Adobe ID, but the eBooks on the other cannot. If you authorize the second computer with your Adobe ID, any subsequent purchases on it are associated with that ID and transferable to any computer authorized with that ID. However, the books that were purchased on the second computer prior to being activated are forever locked to that computer.
You can activate up to six computers and six devices . If you reach the limit, contact Customer Service to increase your allowable activations. --Adobe Web Site

How can I read the image from database into form

hi everyone
if I have table like this
create table test
(id number(10),
pic long raw);
in this table record
in form If I have block non database
how can i read the image into non database item
I try with this code but no good
select pic into :photo from test where id=5;
photo its non database item kind image
how can i invoke image into item
thanks alooooooot

Hello,
You can't select image with select query. You need to create another database block from test table which has item binds with database pic column. Now in where condition in test block's property you have to write id=5. Change test block's properties UPDATE ALLOWED, INSERT ALLOWED, DELETE ALLOWED to NO. Only Query allowed property set to YES.
Now in your particular trigger write the code
GO_BLOCK('test');
Execute_Query;
please mark if it help you or correct
Regards,
Danish

How can I read a comment from an lvm?

Hello,
I created an lvm using the Write to Measurement File express vi and I added a comment.
To simplify it the line of the lvm created was:
5 test
where 5 is a random value and test the comment I input.
My question is how can I read this comment.
When I use the Read Measurement File express vi, the comment output
returns empty.
Thank you.
Solved!
Go to Solution.

Hi epik78,
I am not sure how you are adding your comment to the file, but when I made the simple VI below, I was able to see the comment that I input to the .lvm file in the comment indicator of the Read From Measurement File.
Regards,
Stephen S.
