• How to find the sampling frequency to read the measurement file

  Hello

  I would like to find/extract the sampling frequency of a .lvm file.

  Right now I am using the VI 'read file of measurement' and my data charge fine and all, but I need the frequency of sampling for certain calculations.

  I know the header of the file .lvm that the sampling frequency is 1613Hz, but I want to get this automatic information from the open file .lvm.

  Tried to find an express vi that could give me the answer, but I could not find a

  I'm sorry if this question already answered, but I could not just to find the answer.

  I hope you understand what I'm doing!

  Thank you

  The timing is part of the production of signals information. Never use the functions of the Express, but you can use DDT to and convert to one of the data types of waveform. Waveform components then turns the dt.

• How capture and save a sequence continues to images using NI 1422 LVDS card capture, through Measurement & Automation Explorer?

  It is possible to capture and record a sequence of images with a LVDS OR 1422 EZMaker using Measurement & Automation Explorer?  Everything is installed correctly and running and I am able to use the "Snap" command to save an image, as well as the 'Grab' command, but it seems that you must stop the dump command before you can save anything, and it only allows you to save the final image.  Is there a way to record a sequence that is being caught, or should I use LabVIEW or other additional software to do this?

  Kind regards

  James S.

  Hello James,.

  You will need to LabVIEW or another environment development in order to record a sequence of images. If you have LabVIEW and the Acquisition of Vision software, you will be able to capture and save images in an AVI file. There are examples that come with the Acquisition of Vision software that can do this.

  I hope this helps.

• How to specify the instance in SQL * more command line?

  Hello
  
  I'm learning to Oracle. I currently have 2 instances of database running. I wanted to connect to one of the bodies and used the following command from the command line:
  

  sqlplus system as sysdba/abc123@ocp11gsid
  
  where 1234 is the password for the system user in the ocp11gsys instance.

  When I run the command above, SQL * more ask me the password. I do not understand why he asks me the password because I provided on the command line.
  
  What is the correct command line, so he asks me the password? (without defining the variable ORACLE_SID of environment - basically, I want to know how to specify the user, his password and sid, all in the sqlplus command line, without being prompted to enter the password that I mentioned.)
  
  Thank you for your help,
  
  John.

  John,

  This is how it works.

  Spot the difference?

  The user name and password must unite. What you are to provide the password with the role where it will not be considered.

  Update
  I missed that part,

  What is the correct command line, so he asks me the password? (without defining the variable ORACLE_SID of environment - basically, I want to know how to specify the user, his password and sid, all in the sqlplus command line, without being prompted to enter the password that I mentioned.)

  The only thing that you can specify is the user name and password. The SID must be defined by you, either explicitly using the export or oraenv command if you are on the local system and do not use the TNS to connect to the instance. If you use the TNS, then an appropriate entry should be there which would connect to the required database.

• square pulse time rather than the sampling frequency and size dependent frequency

  Anyone know if it is possible to create a pulse square with its dependent on the frequency at the time rather than the sampling frequency and size?

  for example if I set the frequency to 10. That means 10 pulses per second.

  rather than having to set the sampling rate and use the equation

  frequency = [(# of cycles) * (sampling frequency)] / sample size

  Thanks in advance. a photo of the block diagram would be grateful if possible

  How to specify the color for LR space?

  LR only uses the ProPhoto RGB color space. You cannot specify any other

  color space (work). When you export pictures, you can specify a

  different color space to convert. Or if you use an external editor.

  You can choose what color space to send to the external editor.

• How to increase the sampling rate in this VI?

  Hi all

  I have recently inherited this mess of a VI and can not figure out how to increase the sampling rate. I tried to change the "ms of waiting ' clock, but it does not add more data points." The main VI, as well as the Subvi, which contains a Daq Assistant to a load cell and LVDT is attached. Any ideas on how to improve the sampling without a complete overhaul would be greatly appreciated!

  Thanks in advance!

  If you are grateful, feel free to give congratulations and mark the topic as resolved.

• DT of a waveform is not equal to the sampling frequency

  I wrote the attached VI to take data from two different channels, 1 a cell, and the other being an encoder. I have my calendar synchronized with the entry load cell. The question I have is that at different sampling rates high for the program, does not change my dt in my waveform data.

  If I understand correctly the dt of the waveform should coincide with the sampling frequency. Am I missing something?

  Thanks in advance for your help

• How to remove the variable created when using definedNamedWhereClauseParam()

  Hello
  
  My Jdev version 11.1.1.7.0.
  
  I'm Executive where clause programatically where I need to bind two bind parameters under certain conditions. Example, I have two bind variables X, Y.
  
  Here's the problem:
  
  Assume that the first time I'm setting one variable X, so I define X bind variable and execute the query.
  
  What second time I send only Y but not X. In this implementation of the scenario of VO throw an exception, given that the variable X is already created in the VO object and where clause does not have this setting.
  
  So how to remove variables created in the original Version all in definedNamedWhereClauseParam(). I need to erase what ever the previously created variable every time I execute method.
  
  I can make the similar functionlity using setWhereClauseParam (using literals). But I have a few technical restrictions for use.
  
  Could you please help me how to remove the variable before vo using definedNamedWhereClauseParam.

• How to manage the photos Lightroom when using 2 computers, keeping any changes made on one or the other?

  Based on http://forums.Adobe.com/thread/1308132?TSTART=0 I decided to add each question separately:

  Hello, I am very interested in buying Lightroom 5.2. I tried the RC that was missing today. Yet, I have several questions that I can't find really good conclusive answers, I'd like to get an answer before buying LR. Please do not write maybe like this or that (assumptions), because I don't want to start my entire workflow and then realize that I have to change all around, please reply, if you know for sure that something works and you are, preferably, using this method too.

  Is the big question, where I want to especially a conclusive answer:  How to manage the photos Lightroom when using 2 computers, keeping all the changes made on one of them, using the same photos for editing. I'm not going to use DNG. Details: I mainly use my old MacBook Pro, but I wish I could use my PC as it is much better (card: i5 2500K, 16 GB of RAM, SSD, USB3, nVidia GTX 560 TI etc.). I have 2 external HD that I could use, one for backup and one for the actual Photos/changes. I you will probably need to use as my internal HDs are fairly complete and I cannot be the kind of things simply delete or move to one (developer, without loss of music, programs etc.).

  On this basis, how do I save all such Photos folder (pictures and retouching and preferably presets too)?

  According to me, that it should be possible to work cross-platform without having to create a link to the files each time, or without having to keep export/import of the catalog, keeping the single catalog and the picture library on an external drive that is then switched between systems as needed.

  Obvious first requirement is an external drive that is formatted in a way (for example, FAT32) that it can be used on both platforms in read/write mode. Given that, if the catalogue AND folder parent si le catalogue ET le dossier parent images are both set to the same level in a global parent folder, then it should be possible to take advatage of ability of Lightroom to use relative paths instead of absolute paths to detect the images, no matter if the player is named (Mac) or lettering (PC). This is how "export as catalog of ' works, that is, it creates a 'package', alias a parent folder, containing the catalog and a replica of the folder hierarchy to exported along with the catalog images. Take this 'package' to another system (same OS or not) and "it works" even if the drive letter is different or the operating system is different... because the relative path of the image catalogue is always the same.

  I have not tested this cross-platform (if I have between various PC systems with letters of different readers) so for me it's still just a theory, but there may be others who have done this successfully.
