• Reading EXIF values to THE

  Hi all

  I'm reading the serial number of the camera of http://ns.adobe.com/exif/1.0/aux/ namespace however when I open the file for update to THE namespace is not here, when I look at the RAW files in Photoshop, I can see the namespace is here.

  That's how I opened the update file:

  XMP_OptionBits kXMPFiles_OpenForUpdate aXMPOptionsBits = | kXMPFiles_OpenUseSmartHandler

  
  SXMPFiles aXMPFile;

  bool is aFileOpenOK = apXMPFile. OpenFile (strFileName, kXMP_UnknownFile, aXMPOptionsBits);

  SXMPMeta imageMeta;

  aXMPFile. GetXMP (& imageMeta);

  at this point, I empty everything from file and cannot see the auxiliary voltage

  How can I see http://ns.adobe.com/exif/1.0/aux/ when I open the file updated, suggestions are welcome.

  Thank you very much

  Hello

  you are looking at a raw image file?

  The XMP Toolkit currently does not support raw image files while Photoshop supports raw image files in Camera Raw. This is probably why you can see the properties in the Photoshop FileInfo dialog box.

  For files JPEG, the serial number of the body is part of the standard EXIF for EXIF version 2.3. The XMP Toolkit will map this property to exifEX:BodySerialNumber (exifEX = "http://cipa.jp/exif/1.0/"). To ensure the compatibility of the reasons exifEX:BodySerialNumber will also map to to the: SerialNumber for reading and writing JPEG files.

  So if you can not read to the: SerialNumber the XMP toolkit, either you have a raw image file, the camera does not support EXIF 2.3 or the camera does not have the BodySerialNumber tag.

  Thank you

• concatenation of the values of the fields to update a column

  Hello.
  
  I have several columns in my table. I want to concatenate the value of a column to another.
  
  for example
  
  I want to PASS B value = value of COL B and c PASS.
  
  Is this possible? I know that
  

  UPDATE tbl SET COL B =  COL C + COL B  

  does not, as the Oracle sees it as a mathematical equation.
  

  UPDATE tbl SET COL B =  COL C   

  work, manufacturing COL B is equal to, or rather as value of the COLLAR C.
  
  Let's say COL b John and COL C a Smith, and I wanted to PASS B show JohnSmith, for example.
  
  What is the right syntax? I can't be that far off. Comments or a tip is appreciated!
  
  Thank you.

  UPDATE tbl SET COLB =  COLB||COLC
  OR
  UPDATE tbl SET COLB =  CONCAT(COLB,COLC)
  

• Cannot read every value of the loop iteration for

  Hiiii...

  I developed a front-end which reads the values of serial port and display on the front panel.

  16 channels, which is a string data value. I've separated this string to read the data of each channel, but at the end of the loop for, I can read data only one channel for an iteration, and also I have to store each value iteration in a text file.

  I'm new to labview. Help, please. I have LabVIEW 8.0.

  Attached is my application code.

  This seems quite inefficient. Why don't you use a business structure? Why don't post it your code.

  In regards to the original code, you try to run by using the run continuously? I ask because I do not see a global loop, so it was not clear whether this was intended to present itself as a simple Subvi or "on-demand". If it's supposed to run continuously until you stop, DO NOT USE CONTINUOUSLY RUN it BUTTON. Use a while loop in your VI. Do not forget to place the initialization and close outside of the loop - you don't need to initialize and close the serial port whenever you loop around.

• Change the value in the table after update

  Hi all
  
  I want to update a certain column (column date) after update is made. I can do this using "before the update" trigger. But I'm getting a few problems of transaction when the trigger is written as before the update (error on the side of java, saying data has been modified outside of the transaction). So I was wondering if there is another way to do the same, if I change data after the update takes place. I searched the net and found "can not change the NEW values for this after the update trigger type". Someone knows how to do this?
  
  Thanks in advance!

  Why not use plsql as sybrand said.

  javacall procedure, switch to the folder

  procedure does 2 things
  1 updates table with file
  2. If succesfull update, make your second update.

  PLSQL is there for this kind of thing

• What happens to the values of the variables cRIO restarts?

  Hello!

  I am currently developing a software that runs on a cRIO as a start-up program. I encode a production counter to determine how many products passed the tests. A web server will be used sometimes check this counter...

  What happens to the value of the counter if cRIO power supply is turned off? The counter will reset to 0 when you restart? If so, how to avoid this behavior and restart with the last count?

  Hello

  Of course, what happens to your variables and what is happening in your program depends on... your program.

  If you do nothing your variables, they will have their value by default when the program starts.

  A way to change this behavior is for example save the value of variables in a text file and read these values at the beginning of the program.

  Hope this helps,

• How the change in the value of the slider once out of the mouse in response

  Hi all

  When I used the slide bar to control my device, I answer the value change of slide bar and set the new value on my device. But it will generate the answer constantly when I use the mouse to drag the pointer, which is not my. I just need answer only after the mouse exit. How can I implement this feature?

  Hope your suggestion, thanks a lot.

  Use 2 separate controls instead of the digital screen on the slider.

  For a mouse event on the cursor, update the value of the digital control and do whatever it is you need to do.

  For a change in the value of the digital control, update the value of the slider and do whatever it is that you need to do.

• Textarea conditional display based on the value of the checkbox.

  Hi all

  I have a question regarding the conditional display of an article based on the value of the checkbox.

  I have a checkbox in a region, which is a STATIC LOV:; Y and the text box in the same region. Now I want to show this textarea only if the check box is selected. ??

  Please suggest how to achieve this.

  Thank you

  DC

  Hello

  I guess that you are 4.2 Apex as you haven't shared the same.

  • Create a dynamic Action on change of box which should present the value of the checkbox and update the TextArea element.
  • Then continue as conditional Textarea with checkbox value.

• read the value of the cell in Excel for multiple files

  I'm writing a routine of LabView to read a value from a specific cell in an EXCEL spreadsheet file. I would like to draw the value then spend the following in the file EXCEL file.  In one of the forums I found this LabView VI that works to read a cell value in a single EXCEL file called Read_Value_From_Excel.JPG

  I tried to modify the program by adding a function for loop and list of the folder as shown in Read_Value_From_Excel_LM2. JPG.  This file gives me an error saying 'Incorrect function in Read_Value_From Excel_LM2'.

  I'd appreciate any help that I've been faced with this during a few days and have not been able to find a similar question in other forums. Thank you.

  
  

• Write to the file of measurement with a loop For using the value of the dynamic data attributes

  I looked and looked, but couldn't find a solution for this.

  I currently have 15 points of different data that I try to write in an Excel file.  I have all combined in a table and lie with the function "write into a file position.  However, the column names are always "Untitled", "Untitled 1" etc.  I then used the function 'Set the Dynamic Data attributes'; but for this I have to do 15 different functions "set data dynamic attributes.  It was suggested to use a loop with the function 'Set the Dynamic Data attributes' inside of her, but I can't find how do.

  I have several arrays consisting of 15 different values for 'Signal Index' 'Name of Signal' and 'Unit', but also a unique 'get Date/Time In Seconds' related to 'Timestamp '.  The problem is that the error I get when I try to connect the output with Scripture at the entrance to measure file:

  The source type is dynamic data table 1 d.  The type of sink is Dynamic Data.

  How can I fix it?  I have attached a picture of my installation; Sorry if this is gross (I'm new on this!).  Thank you!

  It will get rid of the error, but it is not quite correct. What you need to do after that is to click on the output or the tunnel entry and select 'replace with the shift register. In addition, the array of values that you have wired to the Signal Index is wrong. Arrays are 0 based. Just wire the iteration Terminal here. And, finally, take the size of the table and this connection to the N terminal are stupid. Don't wire nothing to this.

• Noise DC value of the ini file values

  Hello

  I am trying to build a generator of signals (sine, triangle, sawtooth, square random noise, DC). I managed to get the job of waveform using the signal generator of NOR built based on VI. but I want to add the DC case that I managed to do. but I want the values (magnitude and frequency) to be in an ini file. My idea is manual sets the values in the file, once I run the vi and select the case of DC noise, it should read the file values and the data output and once I have stop, it records the values of dc before returning.

  So, I'm stuck trying to figure how to do this. I hope that I was clear enough. I don't have a code to view since I haven't started yet coding on this part. Help, please.

  Clearly enough explained.

  Take a look at the screw configuration file, found in e/s from file > Config File live. There also many examples n the community, as well as in the Finder of the example, illustrating the use of these. A good starting point is the sample Configuration settings file write example Finder, and reading Configuration settings file.

  Your .ini file will look something like this, once created:

  [DC noise settings]

  Amplitude = 1.234567

  Frequency = 8.901234

  This is equivalent to:

  [Name of section]

  Key 1 = value

  Button 2 = value

  When asked to read a specific key in a certain section, VI only through the file for the named section, and then search for they key the name you provided it. Remember, you will need to know what type of data is when you read back.

  You can use VI writing to modify specific keys in specific sections as soon as you close the file.

  This is one of a multitude of methods, you can use to do this, but are probably the simplest.

• How to read a counter value for the separation of the two edge before meter is stopped by the second edge (6602 Council)?

  I use a timer/counter with DAQmx 6602. I use the separation of two - available via DAQmx cash edge. Count between the two edges works properly, however I do not know how to read the value of the counter during the counting operation (i.e. after the first edge triggered the beginning of the count, but before the second edge triggered the end of the counting). I'll have to wait for the second goes off the edge of the end of the countdown until I can get a counter value. I need to be able to access the current value of the County during the count operation. This was possible in traditional DAQ. How can it be accomplished using DAQmx?

  Ah shoot - I was afraid that this might be the case (for what it's worth, my series of X returned intermediate values, but the material and the underlying driver are quite different)...

  You just need to take one measure at a time or you are buffer several measures of separation of the two edges at the same time?  So just to take one measure at a time, you can set a task of edges of count using the database internal time as the source using an arm start trigger (first edge) and a sample of clock (second Board) to work around the problem.

• Change the decimal point by point in the writing of the measurement file

  Hello

  I use writing to the extent of the vi file to save data. I can't read the text file in Matlab, I guess that is because the decimal separator is a comma.

  Y at - it than a simple means of LabVIEW to set the decimal separator to be the point instead of the comma? (in writing to measure file vi)

  now, the data is like this 56 897 but I like it in the format 56.897

  Thank you

  Hi simo,.

  Uncheck "use localized comma" in Options-front help?
