Help with "reader"

I need to have a "reader" be able to read my pages in order. What do I need to do to make my site read in the correct order and skip unnecessary text such as "visited link"?

An Automated reader such as Jaws or Windows Eyes needs to navigate the page in the correct order. Does that help clarify?

Need help with read/write to MODBUS RTU registers in Labview 8.0

I’m trying to write and read the registers in G3800xx016. controlling temperatures and lightning. Please look at the attached pdf file for this unit..
I have used Lookout for about three years, and it works fine.. Now I want to expand my system and try to use Labview 8.0
My temperature register start adress is 100 Hex (256 dec) I read from Register with Function code 03.
This register have values from 0-255 witch mean in labview for me as unsigned byte U8
I read my temperature from the register like this: eks.: 40257 lets say value=5
Slave    FC       Start Adress     Byte     Value               CRC
01        03        0100                02        0005                7847
This is the status received from the Modbus tester when I use null-modem connection..
I receive the same value if I use Modscan32
I have used null-modem cable to read out the values.
I have also PIR detectors that control movements and light of and on, and I read these starts at 40017.1
01   03     0010     02
The register to switch on and of heating and lights starts at 404097.1 FC16
Values mention here is read from Lookout 5.0
I have tried examples and read for weeks about this, but everything stops when I try to use Labview 8.0    I can’t read any values from my Master unit, neither write to it, or read any values in Modbus testers when I use null-modem cable.. I have tried different baud rates in my serial connection and it works perfect in Lookout, but Not Labview..
I have even bought DSC module, but I can’t write to either com ports or Modbus testers..
Please anybody… is there anybody that can give me help with this??
Start address for for PIR detectors is 40017.1 (FC03) and for writing bits for on of to light and heatsystem is 404097.1 (FC16)
I would be very happy for any idea that can give me some positive results… Look at the attached pdf file.
Thanks.. and very best regards from
Benjii…

Hi... and thanks for your answer..
Yes, I have downloaded the NI Modbus drivers.. I have downloaded that one + a lot of other things about Modbus..
I have also tried communication between lokout and labview true null-modem cable.. and it works..
I have tried several Modbus examples and I communicate with most of them with null-modem cable.
I write to the right registers as well, cause I use Modbus scanner to read the information..
I have used the same settings for serial communication as my Master device use, bust still I can't get any response..
There was an error message in one of my example from the Modbus INIT module.. Maybe I should try to set up a new connection using VISA ??
Maybe the problem is to INIT my serial port? I have tried restarting my computer after closing my system.. But still, I have the same problem..
I hope you can give me any idea...
Thanks again.. by the way.. is it possible to write and read directly to serial port with the DSC module?? If so.. how??
Very best regards..
Benjii..

Help with Reading values from static table in a .pdf file

Hi guys,
Pls try to clear this doubt of mine.
I basically have 2 files. Both are .pdf extension and they have tables in them. I need to compare certain values in one file with the corresponding values in the other table in the second file.
I need to do this programatically in c# . net
I have tried using packages like pdfbox and stuff which convert the pdf file into text. But cant I get the table as an object or something using which I can access the required rows and columns?
Also, these tables are static information. They are not a part of a form or anything like that.
Please help me with this.
Thanks.

Help with reading information coming from a software into LabVIEW through Serial port

Hi,
I am new to LabVIEW and also an amateur in using RS232 for communication. I have this software that has these icons like speed increase/decrease, elevation up/down, start/stop. Now, when I click these buttons on the software, they perform the appropriate functions. For example, if I press start button, the signal must go through a serial COM port into LabVIEW to start the machine. How do I do that? How do I find what format the code word is when I press a button on the software? And how to decode the information to read whether the button pushed is start etc...? Any help would be appreciated.
V
I may not be perfect, but I'm all I got!

That information would be in the programming manual for the device you're controlling. Unless you have a device that has no documentation or you cannot get the documentation that's the first place you should look. If you cannot get the documentation at all then you've got some reverse-engineering to do. To do this you will either need a serial port sniffer (a hardware device), or you can try to use a software-based port capturing program. On Windows PortMon is the most prevalent. This will show you how the port was configured (baud rate, stop bits, etc). Warning: the information is technical.
As far as how to get it running in LabVIEW, you should take a look at the serial port communication examples that ship with LabVIEW. The most problems occur in figuring out how to (a) terminate a write command, and (b) determining when to stop reading. For (a) this is typically done by appending a carriage return or linefeed to the command. This is device dependent. For (b) this is usually done by the byte stream ending with a character like a linefeed. Again, this is device-dependent.
You may also want to peruse this KB article: Serial Instrument Control Tutorial. There are also lots of tutorial on the internet for basic tutorials on serial port communication.

Need help with reading XML using File Adapter

I have created a simple BPEL process that uses a file adapter to read files containing XML messages of a simple xsd schema. But when reading the xml, I get the following error message:

Thanks for your response.
I am not sure if there is any easier way, but I tried out the following tool available on the net to check an xml against a xsd:
http://tools.decisionsoft.com/schemaValidate/
There were a few issues, that I corrected and finally had a xsd and xml that were matching and valid. I tried this out in my file reading BPEL process, but the error still remained the same!
Here is my updated/simplified xsd and xml:

I even tried the option that is available in JDeveloper to generate a sample xml from a xsd (when in the context of a Transformation activity). The xml generated by this also seems exactly like the one above.
So, I am not able to figure out why my BPEL process errors out with the message Invalid xml document.

Help with Read/Write File

hi I was wondering if someone can help me do some read/write file with java. here is what I want to do:
Read a file and search the whole file for a word such as "throw" and print out the rest of that line to a new file. in the case of "throw", i want to link all thrown exceptions to the file that contained them.
can someone help me out and let me know what way I can approach in this?
any help would be greatly appreciated.
thanks!

Rough and dirty, here's a class that will read a file and return a resultset:
import java.io.*;
import java.nio.*;
import java.nio.channels.FileChannel;
import java.util.*;
import java.text.DateFormat;
public class Utils{
     File fileName;
     FileOutputStream outputFile;
     boolean closeChannel;
     //Constructor
     public Utils(String directory, String filename){
          String strFileDir = directory;
          String strFileName = filename;
          File fileDir = new File(strFileDir);
          fileName = new File(fileDir, strFileName);
          // If directory does not exhist, create it.
          if(!fileDir.isDirectory()){
               if(fileDir.mkdirs()){
                    System.out.println(fileDir + " created.");
               else{
                    System.out.println(fileDir + " could not be created.");
public ArrayList readText() throws IOException{
          // Read content of file into a collection
          ArrayList arrayList = new ArrayList();
          try{
               BufferedReader in = new BufferedReader(new FileReader(fileName));
               String line;
               while((line = in.readLine()) != null){
                    arrayList.add(line);
               in.close();
          catch (IOException ex){
               throw ex;
          return arrayList;
     }And here's how you use the class:
// Create a new Disk Utilities object. This can be used for all subsequent read/writes to this file.
          Utils utilTest = new Utils("e:/testing", "Testing.txt");
// Create a collection to hold the data from the file.
          ArrayList arrayList = new ArrayList();
          try{arrayList = utilTest.readText();}catch(IOException ex){ex.printStackTrace(System.err);}

Please help with reading crash report?

Hi, Dorian.
You are describing the following message:
That indicates a kernel panic. Likewise, the log you posted is a panic log, not a crash log.
The following line indicates the panic was caused by a Page Fault:
panic(cpu 0 caller 0x001A3135): Unresolved kernel trap (CPU 0, Type 14=page fault)...
A common fault type, a Page Fault indicates the processor could not access either data memory or the next instruction to be executed. Potential causes include RAM problems, hard disk corruption, and programming errors.
Since there are no kernel-loadable extensions in the backtrace, the panic log offers no easily-discernable additional clues. I suggest you be sure you are running the latest version of Parallels: earlier versions were known to cause panics.
See my "Resolving Kernel Panics" FAQ. This FAQ includes step-by-step instructions for identifying and resolving some of the most common causes of kernel panics. The FAQ is a roadmap: start at the beginning and work systematically through the end, i.e. the "If all else fails..." section.
Good luck!

I need some syntax help with reading some values from a selected row in an Access form.

My goal: to extract the data from 4 fields in a datasheet row and place them in another form.
My problem: I can only get the field values from the first row of the datasheet.
I have tried using the Form_Click event as the location for the code I've tried. This seems to be the right place, but apparently referring to the desired fields by their names with Me. in front just references the first record in the datasheet, not
the one I've selected.
Should I just read the source form's recordset using the Currentrecord value somehow? I could use some direction on that.
Thank you.

It's generally considered good forum etiquette to post back a description of the solution which you've reached.
The normal control for a multi-valued field is a combo box rather than a text box, but unless it is necessary for you to use a multi-valued field, i.e. your database is interfacing with SharePoint in the very limited context in which this feature is necessary,
I'd advise that you model the many-to-many relationship type in the time-honoured way by means of a table which resolves the relationship type into two one-to-many relationship types, and use a subform to show the data. You can alternatively use a multi-select
list box or a text box which shows a value list. You'll find examples of all three methods in StudentCourses.zip in my public databases folder at:
https://onedrive.live.com/?cid=44CC60D7FEA42912&id=44CC60D7FEA42912!169

Help with reading in a text file and arrays

I need to read in a text file with info like this for example
dave
martha
dave
billy
I can read the information into an array and display the names but what I need to do is display how many times the same name is in the file for example the output should be
dave 2
martha 1
billy 1
How can I accomplish this? Would I use a Compareto Method to find
duplicate names?

Hi,
I would recommend storing them in a Hashtable.. something like this:
Hashtable names = new Hashtable() ;
String s ;
while( ( s = bufferedReader.readLine() ) != null ) {
    if ( names.contains( s ) ) {
       names.put( s , new Integer( names.get(s)+1 ) ) ;
    else {
       names.put( s , new Integer( 1 ) ) ;
}Then the hashtable will contain a set of keys and values, which are the names and counts respectively.

Need help with reading RSS feed from SSIS

Hi all,
I am trying to read RSS feed from SSIS by using the Script Component. So far I am able to read some information from the RSS feed from the following items included in the code, Title, PublishDate, LastUpdateTime, Id and Summary.
There are still more item but I am unable to identify the proper data type for the following:
//Output0Buffer.Description = item.Content;
//Output0Buffer.Category = item.Categories;
//Output0Buffer.Comments = item.Summary;
//Output0Buffer.Source = item.SourceFeed;
When I define the data for item.Content as Unicode String in the column properties for the Output column I get the following error message:
Error 1 Cannot implicitly convert type 'System.ServiceModel.Syndication.SyndicationContent' to 'string'
And the same error for the other three variables.
I am using HTTP Connection manager to read the xml link.
I tried to google around for some help but I could not find more information about the datatype.
I appreciate any help if someone can point me to the right solution for reading RSS feed from SSIS.

You need to make it running outside SSIS 1st. I just do not see why you need to publish it here at the moment.
And to solve it, doesn't C# has the

Hey guys, I was reading about how the new iPhone/iPod has a retina display and I just read that the new iMac has a 5K Retina Display quality, BUT I've never seen these screens in real life. Do these screens make reading e-books easier or better?
My current screen for my Mac Mini is a Dell LED at a resolution of 1080P. How would this compare to an iPhone with a retina display or the iMac with 5K? How do I compare them in terms of numbers???

If I were to buy a 5K screen like from Dell or Acer, could my Mac Mini power it?

Help with reading files!!

OK.. so I am working on a very basic encryption/decryption program..
When it reads a unencrypted file it uses this:
public static String readFile(File f) throws IOException
             StringBuffer sb = new StringBuffer();
          BufferedReader in = new BufferedReader(new FileReader(f));
          String line = "";
             while((line = in.readLine()) != null) {
                 sb.append(line);
             in.close();
             return sb.toString();
     }It runs the next bit of code to read the already encrypted files:
public static String readEncFile(File f) throws IOException
             StringBuffer sb = new StringBuffer();
             return sb.toString();
     }The only problem with this is that when it reads the unencrypted data it gets rid of ALL of the carriage returns (aka new lines).. It HAS to make it all one line or it will cause errors when it tries to encrypt..
Basically what im asking is.. rewrite my code to make it get rid of the carriage returns in the first bit of code and then replace them in the second.. or atleast point me in the right direction..

If it doesn't matter where in the new file you put new lines, just write a specific number of characters (e.g., 80) [using BufferedWriter.write(String,int,int)], then write a newline character [using BufferedWriter.newLine() ]. Continue until all characters are written.

Help with reading XML file

Hi,
I have a piece of code:
import org.w3c.dom.Document;
import javax.xml.parsers.DocumentBuilder;
import org.apache.commons.httpclient.HttpMethod;
    private Document xmlDoc;
    private DocumentBuilder docBuilder;
    private HttpMethod method;
    xmlDoc = docBuilder.parse (method.getResponseBodyAsStream());When I execute the last line, I get a nullPointerException. I know that my method is instantiated.
    System.out.println ("MyRssReader.readRSSFeed: method==null? " + (method==null) );gave:
MyRssReader.readRSSFeed: method==null? falseSo, the big question is, what is not instantiated? I know that X in
docBuilder.parse (X);can be a File, (abstract) InputSource, InputStream (as I am using), InputStream with URI, or URI. URI in both cases as String.
I can get the RSS feed as a String, but see no way to get that String parsed.
Abel
PS: I also tried
xmlDoc = docBuilder.parse (method.getURI().toString());and
xmlDoc = docBuilder.parse (method.getResponseBodyAsStream(), method.getURI().toString());EDIT:
Reading the parse method in DocumentBuilder I see it checks if the InputStream is null. When it is null, it raises a
new IllegalArgumentException("InputStream cannot be null");As I do not see that exception, the InputStream is instantiated.

Added part about DocumentBuilder.parse(InputStream is)

The stack trace I got is:
