don't read full of binary data from the db

• Set the following fields in 'read only' to take data from the first occurrence?

  Hoping that this can be easily done without the need for scripting.

  I'm working on creating a form of proposal. There are a few areas where I would like the first instance of an editable field, but the rest would be locked so that they are even taken out of the tab order.

  Example: On the first page, I have a field for the name of the company. This field is reproduced in the pages of the proposal. Each field has the same name. So all data have concluded one of them are dealt to each of them.

  Ideal solution: Front page field is editable, and is where data is entered. "All the following fields are defined as 'read only' and take their 'master' field data" so someone can't make a change to this form, for example, the third page and have this error repeated throughout the document.

  Is this possible?

  I use Acrobat Pro DC on Windows 7 pro.

  Thank you.

  You use a script to do it, but it's very simple.

  If the 'master' field is called "Text1", then enter this code in the calculation script customized for all other areas that need to have its value:

  Event.Value = this.getField("Text1").value;

• How to convert binary data from the Panel controls in ASCII values?

  Hello

  I seemed to face a roadblock with how to convert binary values in ascii.

  I created this .vi to save all control values in an .ini file and call them at that time where I will carry out the .vi as shown in the file attached. Registration key to simply save the data and Cancel button discards all current changes.

  I would like to understand how to retrieve all the values of control to ASCII, so I assign to a global variable for later use. I've looked everywhere for a good reference document, and I couldn't find one that would explain my question. I would be greatly appreciated if someone could point me in the right direction.

  Thank you

  I tried a simple way to save control values in the front panel

  Not reinventing the wheel, when there are ready to use of solutions, for example:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/209753

  Use the MGI save & restore settings VI of the palette (for example, it records all the settings that have been changed in a graph, which is very useful) and the MGI Save (restoration) Front Panel data live (to save and restore control values in the front panel).

  Here is an example:

  

• How to read the two columns of data from the Port series

  Hello

  I'm reading two columns of data from the serial port.

  Example:

  52439 52430

  52440 52437

  52209 52214

  51065 51070

  52206 52390

  I use the serial of Visa service and I can read the first column of data from the serial port, but I can't understand how to read the second column.

  I want to both sets of chart data.

  I enclose my VI.

  Thank you for your help.

  The analysis of string function takes a "Format string" on top (with the right button of the function and choose Help, which explains all the entries).  In particular, you can say 'Give me two numbers separated by a tab' and the output will be two numbers (whole or floating, depending on the chosen format).  In particular, %d\t%d specifies a decimal integer, , whole decimal.

• 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.

  
  

• Read data from the text column in report

  I have a sql report with an editable column created using apex_item.text (5);
  
  I tried to read and insert the data from the column in a table, using this process
  
  because me in 1.apex_application.g_f05.count
  loop
  insert into table (col_a, col_b)
  values (apex_application.g_f05 (i), apex_application.g_f04 (i));
  commit;
  end loop;
  end;
  
  but without success.
  
  The message when I execute is ORA-01403: no data found.
  
  What is the error?

  HI lkefur,

  Try to debug it.

  The reason behind this is that your report do not have the of4, fo5 (one) as text fields at all.

  try to delete value n f04 normal text and check, even to f05.
  I think that most probably the reason whether shud.

  You can view only the source of the page and check which names are your text fields of the report to help.

• Read data from the file into ArrayList

  Hello
  I have a class called product describing the charactristics of products such as the name, id, price etc.. I have the whole set and use the get methods in my class of product. I store the information on my products in an ArrayList. I can write the information on my products in a file.
  so far, but so good...
  
  I want now to re-read the data from the file and store it in my list of tables again. I know I can use Parsing and read in data in an ArrayList as String, int, double etc. but is anyway to read in from 'Product' (then it would be up to my class of product)?
  
  Thank you in advance.

  1. are you aware of serialization?
  2. get a name, I love not dealing with numbers.

• Store data from the Serial Port in the buffer and then take action?

  Hello! Everyone,

  I'm new to LabVIEW and I take assistance from various videos and stuffs available online to get started with LabVIEW.

  But I have a duty, therefore needing help.

  initially I see some of the tutorial videos and learned about the LabVIEW interface, and does a little project to communicate with the Port series (receiving and sending data).

  Happens to my task.

  My LabVIEW application will send a few State request packets on my device or control and based on the response packet that I have to display values.

  The Structure of package is as

  Header, length, Op_Code, data Checksum

  There is no terminator as newline or carriage return or anything else.

  In C language, I read the data from the Serial Port, and based on the length, I conclude that I got the full package or not, and then by recalculating the checksum value, the integrity of the package is verified and then based on that Op-Code has been sent will be decided.

  (I'm dealing with hexadecimal data)

  But how can I do this in LabVIEW.
  A tutorial or any referece will be useful for me.

  1. I suggest that you learn to use Shift Registers instead of local and global variables.  They are much more efficient (memory and execution speed) and make it much easier to read the schema.

  2. you don't need this inside the loop property node.  Is there a way to configure a Serial Port to turn off the stop character.

  3. you don't need to wait for playback VISA will limit the rate of loop if no data is coming.

  4. Once you have the length, you simply read the rest of the entire message and process it at a time.  This will make things a LOT faster.

  5. you should really do this enum a def type so that you can ensure that all your enum constants have the same values.  If you need to add a State later, simply update your enum in the same place then.

  

• Pulling data from the class on a MovieClip array

  I am trying to create this slideshow application that displays product information (Tennis rackets) issues of different categories. A great programmer advised me that OOP would be a way to go, however I'm having a difficulty with it.

  If I clip named firstScreen how to fill with data from the rackUSA of the table, using the presented functions iterateArray

  I tried in a movieClip

  CustomClass.iterateArray (rackUSA); but it does not work

  Any suggestions

  I want to clarify the use cases.

  1 load data into the document class

  2. display a welcome message

  3 allow users to navigate through the products.

  Q1: Do you mean by 'welcome message' a user interface that allows to start navigation?

  Q2: Products appears the same way. I mean, consider that product display will have a uniform provision?

  If the answer to Q2 is Yes, I would:

  1. create a class that features products. Call ProductDisplay

  2 transfer data (subset of XML related to a particular product - in your case, it may be an object in the position of the table) in an instance of ProductDisplay

  I would like you to consider the following.

  It is a good practice to do OBJECT oriented programming class as little as possible each. This means that a class must have a very focused functionality. For example, ProductClass you perform tasks related to laying on the presentation of the product. With this in mind, it is best to delegate, say, loading image to a separate category. Believe me, when you do – your life will be much easier if you do features as granular as possible even if sometimes it feels like an overdose.

  So here's the sketch of your classes. I wrote it just to illustrate the idea. I did not check the code during execution is definitely buggy.

  Read my comments below also.

  It is a class of product image that load the image:

       {
            // image url

            // loader
            private var _loader:Loader;
            public function ProductImage()
            {
                 if (stage) init();
                 else addEventListener(Event.ADDED_TO_STAGE, init);
            }
  
            private function init(e:Event = null):void
            {
                 removeEventListener(Event.ADDED_TO_STAGE, init);
                 _loader = new Loader();
                 _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoad);
                 _loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
                 _loader.load(new URLRequest(url));
            }
  
            private function onProgress(e:ProgressEvent):void
            {
                 // display progress if needed
            }
  
            private function onLoad(e:Event):void
            {
                 _loader.contentLoaderInfo.removeEventListener(Event.COMPLETE);
                 _loader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, onProgress);
                 addChild(_loader);
  
            }

            }
            // returns metadata
            public function get metaData():Object {
                 return _metaData;
  
            }
  
       }
  
  }
  

  Now in your document class, you can set an unlimited number of instances of ProductDisplay (as slides) and manipulate them. Again, this is just a sketch. Actual implementation of features and code will be somewhat different:

  var productDisplay:ProductDisplay = new ProductDisplay();
  productDisplay.metaData = rackUSA[2];
  
  

  Note: Your code has several inconsistencies - we need to go through them at another time. For now just digest these ideas. I understand that this will involve a refactoring on your part, but once you are done with it - things will fall in place fast.

• Unable to delete the data from the Safari Web site...

  Any help will be great. Please let me know if you need any additional info.

  Thank you.

  Hello DZanvettor,

  Thank you for using communities of Apple Support.

  If I understand your message that nothing happens when you try to remove the Safari Web site data. I know how it is important for you to be able to remove the Safari Web site data. I recommend that you restart your Mac into safe mode and see if you can remove the data from the Web site in secure mode.

  Here are the steps to restart your Mac in safe mode:

  Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening.

  From your Mac in safe mode does the following:

  * Check your startup disk and attempts to fix problems if necessary directory
  * Loads only required kernel extensions
  * Prevents the elements start and the login items open automatically
  * Disables installed user fonts
  * Delete font caches, hiding the kernel and other files of the system cache
  * Together, these changes can help resolve or isolate issues related to your startup disk.

  Follow these steps to start in safe mode.

  1. start or restart your Mac.
  2. as soon as you hear the startup tone, hold down the SHIFT key.
  3. release the SHIFT key when you see the Apple logo appears on the screen.

  After you delete data from the Web site in safe mode restart your Mac and allow it to start up as usual. Then test the issue again.

  Best regards.

• does "set up as new iphone" prevent later restore the data from the old iphone (iphone 4)

  refurb Iphone 4: if I use the option "set up as new iphone", I can retrieve later data from the old iphone from itunes? (macbook 10.6.8 don't dl latest version of itunes @ this time)

  You would be able to restore an old backup him later, but doing so will wipe everything that is currently on the phone. There is no way to combine.

• What pins to use to receive the data from the PDS ELITE RS485 with the PXI-8431/2?

  Hello!

  I use the PXI-8431/2 to read data from the flow meter PDS ELITE (Modbus RTU). Receiving data, the RS485 protocol request to terminals 4 and 5, but this configuration does not seem to work. When I connect the RS-485 converter USB of Microflex I get the data correctly, so somehow between the PIN lay and PXI this problem there.

  Can someone help me?

  See you soon,.

  Hello Steven,

  I think that what was Hossein trying to send you is the following:

  How to connect and configure a device with RS-485 2-wire

  Can you also tell me a little more what you use to read the data? What environment. You have 2-wire or 4-wire Modbus RTU?

  Kind regards

• How to write data from the acquisition of data in NetCDF format?

  I connect to a set of data from the sensor through the DAQ assistant and want to write all data in NetCDF format. I have the required plugins installed, but still can not find how to do this.

  Or the labview can only read the netcdf files, but cannot write it! Please let me know if there is any other way out. I have looked everywhere but could not find something useful!

  Thank you

  Hey,.

  Sorry, the sheet in effect only allows to read NetCDF files, not writing to the NetCDF format.

  Kind regards

• VI do not transfer data from the instrument.

  Hello to all who are interested.  I'm working on an instrument driver for an Agilent D3000A generator of signal (E4432A) trying to get the generator to sweep the amplitude of - 30dBm to-75dBm and then come back in a loop.  The loop is in a structure of the event and is called by a switch on the front panel.  When the switch is selected event triggers and loop information is passed to the VI.  The problem is the 'Sweeping Steps' VI does not use data from the number of points in the sweep and pause at each time and the tracks of the loop as the amplitude is just switching between the min and Max amplitude levels.  But once I have stop the generator program will continue sweeping (only in a sense) but the correct time and the number of points.  When I use the spy "measurement and Automation Explorer" program AND I do not see that the data are transferred in the instrument.  I don't know if the Subvi the execution order is correct and was amazing if someone could take a look and let me know if I have them in one order incorrectly.  Could not find an example of this type of program examples of the driver so there is little help.  I joined the program and the driver of instruments for your comment, then please take a look and send any information you think will help me to get this working properly.  I have also tried to run the single sweep mode sweep and have just the change of direction for the sweep to the other side of the ramp, but I still get the same results.

  The generator has 15th and ONU3 options.

  I, m using LabVIEW 2010 on a Dell Dimension 2400 running Windows XP and service pack Version 5.1.2600 Service Pack 3 Build 2600.
  Please let me know if you need other information.

  Thank you

  Just for the short term, right click on the structure of the event, select Configure the events managed by this case and uncheck the lock front panel.  Also, I don't know if you caught my edit.  I think your problem is your expectation (or lack of).  At your expectations to be slightly more than the number of steps to multiply by the pause time.  You must leave the instrument perform its scanning after all.

• acquire data from the oscilloscope DPO2024

  I am trying to acquire data from the oscilloscope DPO2024 using labview. I am able to do, but my vi file only works for channel 1. Other than channel 1, it does not work and instead, it changes the adjustment of the oscilloscope as well. Find the vi files attached.

  Any help is very appreciated.

  You must connect the channel in the waveform of reading.  It is default to channel 1 if thread continues.
