• Use two assistants for the acquisition of data at the same time

  Hello

  I want to read multiple data channels of analog inputs on my DAQ hardware. However, when I try to create two separate data acquisition assistants for each entry, it gives an error saying "is reserved for the specified resource. The operation could not be performed as indicated "." Can't use two assistants for the acquisition of data at the same time?

  I have to add different channels in the same assistant DAQ? I tried, but I couldn't separate the data in different graphs.

  How does this work?

  Kind regards

  Allard

  You can't have multiple tasks of the same type (in this case inputs analog) on the same device.  Just so having 1 DAQ Assistant read all your channels and separate your channels for individual transformation.

• Lack of voice and data at the same time kills me

  After using a treo 750 (WM 6.1) on att for the past three years, I guess I did not realize the advantage of ATT and gsm in general.  There are many drawbacks... mainly pricing for simple accounts (However their family plan was directly comparable to those of sprint).  I constantly try to use data applications while talking on the phone without success.  I started thinking that I could do without, but a week later, I still really really miss.  My wife did too... because she's I usually give directions or any other web information while on the phone.  There is nothing like view google satellite map to help someone make sure they are in the right place... "see a big tree on your right with a large Brown building behind it, Yes, it's that one" does anyone else have this feeling?  WiFi is not an option for me most of the time.

  Voice and data at the same time is not available when using any CDMA network due to network constraints. This is true for all types of phones, not only Palm or not only the Pre. Your example of electronic control or by using google maps, the gps data that can be stored before you activate the call. try to browse the web while making a call and try to go to a web page, you have never visited before, so that you know, that he cannot be a version collected page.

• How to select data using the same remote database column name 3

  Hello
  
  
  Can anyone help me on how to get the data with the same remote database column names 3 and a unique nickname.
  
  E.g.
  
  SELECT *.
  B.SID, b.status, SUM (b.qty) qantity MAX (b.) date_as_of
  Of
  * ((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) has, *)
  (* (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) b). *
  WHERE b.dept = 'finance '.
  AND a.position = "admin".
  AND a.latest = 'Y' AND (b.status <>"MLT") AND b.qty > 0;
  B.SID GROUP, b.status;
  
  NOTE: the instructions "BOLD" is just an example of what I want to do but I always get an error beacause of ambiguous column.
  
  Thanks to advnce. :)

  Not valid. This makes no sense and breaks all the rules of scope-resolution. And if it is in a single database, or uses tables in databases, is not relevant.

  Each object must be particularly well identified. If you cannot do this:

  select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a
  

  3 objects cannot share the same alias. Example:

  SQL> select * from (dual, dual) d;
  select * from (dual, dual) d
                     *
  ERROR at line 1:
  ORA-00907: missing right parenthesis
  

  You need to combine objects - by using a join union or similar. He will have to be done as follows:

  SQL> select * from (select * from dual d1, dual d2) d;
  select * from (select * from dual d1, dual d2) d
         *
  ERROR at line 1:
  ORA-00918: column ambiguously defined
  

  However, we need to have unique column in a projection of SQL names - so the join of the need to project a unique set of columns. So:

  SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
  
  DUM DUM
  --- ---
  X   X
  
  SQL> 
  

  I suggest that you look carefully at what opportunities are and how it applies in SQL - and ignore if the referenced objects are local or remote, because it has no effect on the basic principles of scope-resolution.

• DAQ Assistant Express Vi to acquire and generate data at the same time in LABView

  Can I run acquire it and generate the Express Assistant DAQ Vi at the same time in a LABView program? I am using LABView 2010.  It's acquire and generate a NI USB-6009.

  Thank you

  Mary

  You can acquire and generate the same VI but obviously you can't generate a wave form unless you do a single point at a time inside a loop with a sample on request and can live with low samples/s specifications.

• How many flv loaded at the same time?

  Hello

  an important point regarding my question is that all flv files that have been mentioned are local, so there is no delay involved download.

  I am writing a multicamera demo application that essentially lets you can switch between different camera on the same topic views: there are 5 flv files: one with four views together in a mosaic (made in editing and exported as a single flv file) more a flv by each of the 4 views.

  the very simple interface allows you to switch views to others, including mosaic view, so that, when a view is opened, the video starts playing at the same moment in time that you where when you clicked on in the previous screen.

  It will never be more than an FLV playing simultaneously, there will be other loading and pauses, but playing alone at the time.

  Since I did not download, my biggest concern is use of RAM and CPU. I use three video objects, one to hold the multicam flv and two for two single cam videos as possible. My question is this: what would be the most time and resources consuming, having three videos 'responsible but constantly stopped' (is an open NetConnection and a NetStream loaded with a clip in the paused state) or opening, loading and launch video at each request?

  Thank you very much in advance,

  José

  the least local resources would be by having a single instance of the netstream and by switching the stream when you want.  because these flows is downloading so there will be a (short) lag when switching.

  If this delay is not acceptable, then you must do what you are currently doing with multiple netstream instances if you want among all instances paused.

• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

• How to acquire data from the memory of the meter

  I am a beginner of Labview. I don't know how to acquire data from the memory of the meter.

  I read a few examples of data acquisition, but apparently not similar to my case. I can't use DAQ in my computer, because I don't have DAQ card.

  Could someone give me some pointers? Similar examples would be great.

  How can I have two virus Gabrielle clocked at sametime?

  When I have only a single virus of Gabrielle, I know, this program is Mcafee.

  It is not recommended to run two anti-virus programs at the same time.  It will make the System unstable, crashes, slow performance and so on.  It is better to use a program that you trust on a regular basis and if you want to double check this program, use a parser in line one of the main websites AV.
