Detecting PDF-image files in real time

Hi,
I'm planning to build a web application that allows users to upload PDF files. I want to be able to check the PDF files in real-time to ensure they only upload PDF text-searchable files, and not PDF image files. Is there anything from Adobe that has this functionality?
I'll probably to integrating it into a .NET web application.
Thanks.

Hi Leonard - thanks for the reply.
I've read up more about Adobe LiveCycle ES and it seems it might be a bit of an overkill for what I'm trying to do. I just need to have some software to check the PDF document whether it is text-searchable or not. LiveCycle appears to be a full document management and processing suite. Is there any more basic Adobe software that can do this kind of check?
Thanks much.

Why can't read access log file in real-time? (Oracle Weblogic Server 10.3)

We can't read access log file in real-time. If access log is rotation to new file so can read access log file but can't read real-time.
*** Oracle Weblogic Server versions 10 R3

what's your meaning? try this command "tail -f access.log".
Threre is a buffer about 8K for WebLogic to write the access info into the log files, so you can't see the access info untill the buffer is full.

XML file issue real time

Hi guys,
My question is in a real time scenario how the file is asked for ?
As for testing a simple file scenario we usually get the sample file in XI from Message mapping tool only, this sample file contains primary tag of message type with attribute of namespace : <b><ns0:MT_FILE_INPUT xmlns:ns0="http://bsptrng.file2file"> </b> "
<ns0:MT_FILE_INPUT xmlns:ns0="http://bsptrng.file2file">
   <Record>
      <Row>
         <FirstName>q</FirstName>
         <LastName>R</LastName>
         <MiddleName>S</MiddleName>
         <City>Dehradun</City>
       </Row>
   </Record>
</ns0:MT_FILE_INPUT>
but when a client will provide us a file it will be a simple xml file like...
<Record>
      <Row>
         <FirstName>q</FirstName>
         <LastName>R</LastName>
         <MiddleName>S</MiddleName>
         <City>Dehradun</City>
       </Row>
   </Record>
As you can see primary tag of Message type with namespace will be missing...
because of that mapping exception is thrown in pipeline service....
<b>My question is how to tackle this ...</b>

How to determine time value of a .wav file in real time as it plays?

Hi all.
I need to build a vi in which a .wav sound file is represented in a Waveform graph, and at the same time, I want to play that file, and have a vertical cursor line running along the Waveform graph, in order to have a visual representation of where the sound track is, in terms of time.
Making the .wav file to appear graphicaly on a Waveform graph was an easy task to do, but then, I was´nt able to extract the time information of that .wav file, at the same time that this file is being played.
This is a very common situation in music players, video players etc, where some kind of graphical artifact, represents in real time where the track is while it plays.

Hi, this is the first ActiveX control I have played with but its really cool.
I read this first: -
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay10/mmp_sdk/iwmpcontrolsinterface.asp
Which covers "The IWMPControls interface provides a way to manipulate the playback of a media item."
Then built the attached sample.
It should now be straight forward to attach the position information shown to a graph control cursor postion.
You will need to set a file of your own choosing in the VI first.
Let us all know if this is what you wanted.

Reading excel files in real time

Hello,
I would like to have a labVIEW program which permits to read several excel files, and collect all data in a single excel file.
I know that it is possible to write a program which can read multiple files.
But I would like to know that if its possible to read files in a real time:
for ex. each time there is a new excel file to read, the LabVIEW program read it automatically and add its data to the final file?
Thank you and bests regards

As Sam notes, it is certainly possible to merge Excel Files (I've done it, myself). An oft-repeated Best Practice for Program Development, which I didn't understand nor start following until quite recently, is "Write the Documentation First". In this case, you want to think carefully (and specify in a Document, which tends to "clarify your thinking") a number of issues:
Where will you look for the Excel Files to be merged? [Hint -- it's much easier if they are all in the same Folder).
Where will you save the Merged File? Will it be in the same Folder as the Source Files?
How will the Merged File be named? This can have an interaction effect with the previous points.
What is the structure of the Source, and of the Merged, File? Is it "obvious" how the Merge is to take place?
Related to #4, are there Headers? Multiple WorkSheets?
How do you know when it is time to Merge? Are you checking for new files periodically? How often?
In some ways, these "structure" questions are trickier to design and thornier to deal with than simply reading data from two Excel Files and writing the data to a third (which I'm calling a Merge). Note that I'm assuming that you are really dealing with Excel files (.xls, .xlsx), for which I recommend using the Report Generation Toolkit. If you are speaking about Comma-Separated Variable (.csv) files that LabVIEW calls "Spreadsheets", the above questions are still mostly relevant, but your approach will be a little different.
Write yourself a Document, show it to us, and if you have ideas on how to do this, give it a try and show us your code -- we'll try to provide assistance if you "get stuck".

Are the image files on a Time Machine backup password protected?

I have had a hard drive hooked up to my AirPort Express, backing up my computers to it using Time Machine.
Now, the hard drive is broken and I have to return it to the dealer to have it replaced as it is still covered by their warranty.
My question is, will they be able to access my personal data?
I have to enter a password to access the disk over the network, does this mean the image files on it are also password protected?
I know it's not very likely they have any interest in browsing my files, but I don't like the idea to just give everything away.
The disk won't spin so I can't format the drive.

If the disk isn't spinning it is unlikely to be repaired.. And if you passworded the disk people would need the password to access although given time all those things can be broken.. I would say you have little to fear.

I don´t hear mp3 file in real time... why?

I`m using mp3 at 120 kbps 44 khz, but always hear a stupid BEEP...
Can I hear mp3 in real time?
Thanks in advance

You don't hear it because it isn't in an FCP native format.
Assuming you're on a DV timeline (or any other with the same specs), take it into Compressor or iTunes and convert to 16 bit 48 kHz AIFF, and you'll be fine.
It is said that you can also export to AIFF from FCP and then reimport.

How to read data from a .txt file in real time

Hi
I am running a fortran code which takes around 1 week to run and output data are continuously saved in .txt files. I want to display these data and plot it against time in labview.
Lets say I have a array of real numbers starting from 1.0 , and every 2-3 sec another number is added (output of code). So I dont want end-of-file-reached error in my program and also want program to wait until next data is updated in .txt file.
I tried to make a simple read_txt_file.vi, but I am getting problems in terms of continous reading. Help !! Help !!
Pl see the attached vi.
Thanx

Using Scanner and FileReader to read from a file in real time

Hi
I would like to read continually from a text file (which is continually being appended to) and display each line as it appears in the textfile (in a text area).
What I would like to know is do I have to continually reopen the file (using FileReader) and buffer it into a Scanner everytime I want to read the changes made to it? There must be a better way.
Much appreciation for any help.

Umm .. I hope you're doing that in a separate worker
thread as otherwise you would block the EDT from
processing events like paint (thus never showing you
anything you append to the text area).Well that code fell under the run method of a class that is seperate to the main class, so it was called in a new thread. In desperation I've tried calling threads within threads (dangerous I know): remoteHandler's run method is called by a JButton's action listener...
private class remoteFHandler implements Runnable {
     int lineNum;
     int win, x, y, count, num = -999;
     remoteFHandler(){
          lineNum = 0;
     public synchronized void run() {
          while(showScreen == true){
               readingRF = true;
               innerHandler read = new innerHandler();
               Thread t = new Thread(read);
               t.start();
     //Wait 5 a seconds before checking if there is anymore text
             try {
                     textArea.append("Waiting to reopen \n"); //DEBUG
               t.join();
               wait(5000);
             } catch (InterruptedException e){
               System.out.println("File reading interrupted");
               return;
            }// while
          readingRF = false;
          return;
     } //run()
     private class innerHandler implements Runnable{
          innerHandler(){
          public synchronized void run(){
               try {
                    outFile = new File("/data/wrmwind_08/testText.txt");
                    if (outFile!=null) textArea.append("File last modified: " + outFile.lastModified() + "\n"); //DEBUG
                    fs = new Scanner(new BufferedReader(new FileReader(outFile)));
                    if (fs!=null) textArea.append("File opened stream \n"); //DEBUG
                    fs.useDelimiter("\\r");
                  } catch(IOException e){
                    System.out.println("Problems opening file. IO exception: " + e.toString());
                    return;
                  if (fs!=null){
                    readAndDisplay();
                    fs.close();
                    fs = null;
                    if (fs==null) textArea.append("File closed \n"); //DEBUG
               return;
     }//innerHandler
        private void readAndDisplay(){ //reads from a file and displays in a text field until there are no new lines then returns
     }//readAndDisplay()
}//remoteHandlerThe strange thing is that the when I modify the text file while the program is running, that time of last modification is detected and displayed in the text area yet I can't get to read the new line that's been added....

Apps to mix sound files in real time, using two soundcards?

Can someone recommend some applications for linux to mix audio files (mp3, ogg) between two soundcards?
in realtime... you know, like DJs do, etc...
TIA, and sorry for the bad english
luciano

I think if you use more than one card at a time you're going to run into latency issues, since there is no guarantee that the output from two or more cards will be synchronized. If you really need more than two channels out, a better solution is to purchase a professional card with as many outputs as you need. Also, I don't think Jack (the standard for audio work in Linux) supports the use of more than one card at a time.
I can't think of a reason you would need more than two channels (one left, one right) unless you're trying to DJ in surround sound. Don't DJs using traditional gear just run a pair of turntables through a crossfader?
I haven't used the program, but Mixxx looks like the best Linux software for DJing. You might take a look at it first.

Can I generate a report file in 'real-time'?

Hello all,
My question concerns reports in Teststand. Currently, the report is not generated and no results are saved until the entire execution is complete. This is OK if there are no problems during the execution (which can take several days), such as the PC locking up, etc. If this happens, the all the results are lost!
This has happened twice now, so I was wondering if there's a way to set it up to record the results as the test is run, and generate the report file at the same time. Basically, so if a problem crops up, we can reboot the machine, or restart the testing, and all the results we had before the problem will be recorded.
I'm probably making this way more difficult than it needs to be!
Thanks in adva

Dave,
I am doing all our report generation in text mode, as I didn't want to use the html format for legacy reasons. Without looking at your implementation I cannot say why it's doing what it is... However, I know that I talked with NI Tech Support when I implemented this example over a year ago, so they should be able to help with getting the example to work with the default process model. You should be able to set some break points to see what's happening in the process model after each step to see why you're not seeing any results on the fly. I do remember that it required some copying and pasting from several sections in the process model. Once you get it running properly, stepping through it should give you a good idea of where you'd want to ad
d a routine that writes to a log file as the tests are conducted.

3D position using camera system - real time

Greetings!
I amtrying to use Labview to track an object in 3D space. I am using threehigh speed cameras which are connected via a framegrabber to my PC. Theidea is that I want to be able to throw an object, let’s say a ball, and haveLabview detect the motion and return real time stats on the object (location inxyz and the velocity vector). The object should be about the size of abird as this will be the final object tracked.
I amcurrently constrained as to where the cameras can be. They have to bepositioned in a horizontal line beside one another, but they can be turned toany angle I see fit.
Ihave some ideas of how to approach this but since this is my first visualproject I am a little unsure what the best method will be.
Oneidea I had was to have one camera centered facing strait forward and one cameraon either side if it turned 45 degrees toward the center line of vision. Thenthe idea would be to calculate the actual x-y-z position based on the geometryof the camera. However this method isless than flexable.
Anotheridea was to eliminate restrictions on the camera positions and have some sortof target system set up which would then "calibrate" the cameras foreach particular setup. I am thinkingof x and y rulers printed out and hung from the ceiling. Then, using the distances between x ruler markingscompared to y ruler markings to determine the camera angle and what the zcomponent should be. Maybe use a basketball to calibrate instead?
Solutions?Working code that takes jpegs from three saved camera files? Any help atall in 3D positioning would be much appreciated.
Thanks inadvance!!
~Chad

Chad,
Having all three cameras in a straight line is a poor choice for 3D work. Try putting one at (1,0,0), one at (0,1,0) and one at (0,0,1) or some similar distribution. Then the angle from the camera axis gives you a starting point for your 3D geometry.
Can you arrange that the object is always in the field of view of all three cameras? Do the cameras/lenses distort off-axis images?
If the object is a known size and has a simple geometric shape (sphere, cube, tetrahedron), you may be able to also use size of image to get an estimate of distance. Rotation of more complex shapes makes for a difficult calculation.
The rulers might be helpful if the object size is known. If the object size is unknown or variable, the challenge is much greater.

Detecting renaming a file

Hello all.
I have a file "file1.txt" which is being read from a BufferedReader of a FileReader.
This way, any new line appended to the file is read within the Java program.
E.g. $ echo "new line" >> file1.txtThe line "new line" is detected by the FileReader.
Now, if the file is renamed in the file system (Unix), the FileReader continues reading from the renamed file.
E.g. $ mv file1.txt file2.txt
$ echo "first line" >> file1.txt
$ echo "another line" >> file2.txtHere, the FileReader reads "another line", not "first line", because it is attached to the old-renamed file.
What I want is to detect the file renaming, so that at that moment a new FileReader is created to continue reading from the new "file1.txt".
Using File.exists() is not an option, because another process (logrotate) creates the first file again.
If File class API provided the file descriptor it could be a way to check the renaming, but unfortunately it does not.
Any ideas?
Thanks in advance.
God bless,
Jaime

Thank you for your ideas, Owen.
However, I see the following problem with re-opening the file (correct me if I'm wrong):
I want to detect any new line in real time. If the BufferedReader is closed and re-opened again, I have to store the number of lines to be skipped in a variable, before reading the next one.
I think it is time-consuming (closing, re-opening the file, and skipping all the already read lines, for each new line to be read). And the response time for reading a new line is important.
Regarding the design: using JMS is surely a good idea, but in this case I have no choice, because I cannot change the way the monitored systems are logging: they write into plain files.
Regards,
Jaime
