Read data out of htm-file

dear guys
i got the problem that i want to get some data out of a htm-file. that is why i have to choose a format that is more "universal" than an excel-file
the problem is i got a excel-file and save it as htm/html - file because i got a excel-book with more than 20 linked spreadsheets in it and there is
no other format in excel that can handle this linking by being universal enough to start my program on some other pc's
so i dont want to manage it in excel because there are usually some version-conflicts using the original program of the project i am working on.
so is it basically possible to get data out of a htm-file and if the answer is yes how....??

Tobias,
there could be several ways to solve your request.
As far as i understand you like to create an offline analysis of your data. Datasource is excel.
If you can switch to "online analysis", you could use ActiveX to fetch data from excel and perharps write results back to it from LV.
If you stay offline, you have to choose a mechanic which works out for you. Since it seems to me that the file format is kind of given, you have to go through the analysis regardless of its effort (which can get very ugly....).
In any case, you can view a file as a stream of data. The only question is how this stream looks like. This defines how you have to interpret the stream. ASCII-files can be interpreted very easy since you can use all the nice stringfunction (search and so on). Disadvantage is that these mechanics are slow. Binary files are faster, but you have to know very good how the file was created.
Again, in any case, you have to know where the data are....
So i fear that you have to go the whole way and analyse the files to know where to search for your content.....

Read data from a sequential file to fill an arrray

I am trying to read data from a sequential file to fill an array and then use the array for calculations. I believe my program is reading the file; however when I try to use the data for calculations the results show up as boxes rather than numbers. Can someone please take a look and give me some insight into where I am going wrong. The sequential file has the following data:
5.0
5.35
5.5
5.75
Here is my code from that portion of the program. I can send the entire program if necessary.
private void calcResults(TextArea loanResults, double amount, double interest, int term ) throws IOException {
     DecimalFormat df = new DecimalFormat("$###,###.00");
     NumberFormat formats = new DecimalFormat("#0.00");
     StringBuffer buffer=new StringBuffer();
     loanResults.append("Month No.\tMonthly Payment\t\tInterest\t\tBalance\n");
     double monthlyPay = amount*Math.pow(1+interest,term)*interest/(Math.pow(1+interest,term)-1);
     monthlyPayment.setText("" + (formats.format(monthlyPay)));
     double principal= amount;
      * Loop through each month of a given loan
    int month;
     for (int i=0; i<term; i++)
try {
     int j = 0;
     BufferedReader in = new BufferedReader(new FileReader("rates.txt"));
     String temp = "";
     while((temp = in.readLine()) != null) {
        j++;
        strRate[j] = temp;
        RateValue1 = Double.parseDouble(loanAmountTxFld.getText());
        in.close();
         catch (FileNotFoundException e) {
             System.out.println("Can't find file rate.txt!");
             return;
      month= i+1;
      double rate =principal*interest;
      double balance=principal+rate-monthlyPay;
      loanResults.append((month) + "\t\t" + (formats.format(principal) + "\t\t" + (formats.format(rate) + "\t\t"
                        + (formats.format(balance)     + "\n"))));
      principal=balance;
      GraphArea.append(formats.format(balance)     + "\n");
*Method for determining which loan option was chosen
private void calc() throws IOException{
String interestTerms = (String) cOption.getSelectedItem();
if (interestTerms.equalsIgnoreCase("5 yrs at 5.00"))
     calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), 0.05/12, 60);
else if (interestTerms.equalsIgnoreCase("7 yrs at 5.35"))
    calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), RateValue1/12, 84);
else if (interestTerms.equalsIgnoreCase("15 yrs at 5.50"))
     calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), 0.0550/12, 180);
else if (interestTerms.equalsIgnoreCase("30 yrs at 5.75"))
     calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), 0.0575/12, 360);
else if (interestTerms.equalsIgnoreCase("       "))
    calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), Double.parseDouble(loanInterestTxFld.getText())/100/12,Integer.parseInt(loanTermTxFld.getText())*12);
}

ok, I fixed my program per your suggestion and I still cannot get it to work. I get the same result where the ouput is just a bunch of boxes. I also tried to print to see what I am getting and all I see is the values of the array [5.0,5.35,5.5,5.75] but I cannot seem to pass that to the calculations. I wish I could figure this out. Does anybody have any suggestions as to what I am doing wrong. This is the portion of my code that I am having issues with:

View Object to read data from a java file

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
For one of my view objects , I want the data to be read from a java file which exposes some method to return a collection.
I cannot use a static view object in this case.
Please suggest the best way to implement this requirement.Basically build a view object that should read data from a java file.
Thanks,
Praveen

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

Read data from a text file, one line at a time.

I need to read data from a text file, and display each line in a String Indicator on Front Panel. It displays each line, but I get Error 4, End Of Line, unless I enter an extra line of data in the file that I don't need. I tried Read From Text File.vi, made by Nat Instr, and it gave the same error.

The Read from Text File.vi reads data from a text file line by line until the user stops the VI manually with the Stop button on the front panel, or until an error (such as "Error 4, End of file") occurs. If an error occurs, the Simple Error Handler.vi pops up a dialog that tells you which error occurred.
The Read from Text File.vi uses a while loop, but if you knew how many lines you wanted to read, you could replace the while loop with a for loop set to read that many lines from the file.
If you need something more dynamic because the number of lines in your files vary, then you could change the code of the Read from Text File.vi to the expect "Error 4, End of file" and handle it appropriately. This would require unbundling the error cluster that comes fro
m the Read File function with the Unbundle By Name function, so that you can expose the individual error "status" and error "code" values stored in the cluster. If the value of the error "code" is 4, then you can change the error "status" from true to false, and you can rebundle the cluster with the Bundle by Name function. Setting the error "status" to false instructs the Simple Error Handler to ignore the error. Otherwise, pass the original error cluster to the Simple Error Handler.vi, so that you can see what the error is.
Of course, if you're not interested in what the errors are, you could just remove the Simple Error Handler.vi, but then you wouldn't see any error messages.

Reading data from an excel file

You might want to look at the POI project (an open source Jakarta sub-project) that allows you to create/modify/read excel files via Java code. That might be more flexible and easier than what you're currently trying to do.

Problem loading swf which reads data in a local file

Hi,
Using flex with a online project, I have to load a swf file, which reads data in a xml file (it works fine if I open it with flash player)
I do a very simple test :
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                layout="absolute"
                minWidth="955" minHeight="600"
                >
    <mx:SWFLoader id="swfloader" source="data/player.swf"/>
</mx:Application>
The result is that player.swf can't read the xml file (error : Error #2044: ioError non pris en charge : text=Error #2032: Erreur de flux. URL: enonce.xml).
I do the same test with an AIR project, and it works fine !!!!
It works also if I put the xml file directly at the same level as my compiled application (in bin-debug for instance).
I think that it's a path problem, but I don't know how to set it.
Is there any way to solve the problem ???
Thanks a lot !
Olivier

Hi,
Thanks for your answer, but I am not sure to understand it.
What code I have to adjust :
- the code of the swf I load ? It's a problem because I don't have access to the source code : my customer provides me only a swf file (with the xml file), and I have a lot of others swf files that work the same way, I can't ask him to modify everything.
- the code of my application ? I don't really see how to use LoaderUtil.createAbsoluteURL, because when I debug, I see in the SWFLoader code that when this method is called, the returned url is good !
Thanks for your help.

Reading data from a serialized file(Data is in special characters &symbols)

Please help me.... I struck up at reading data in a serialized file. It is a text file with some special characters. My question is - Is it a real serialized file or some bad file? If it a real good one please tell me which method i have to use to read? Actually i have to read records with time stamps from this file and have to do some calculations on them.
FILE CONTENTS :
¬í sr java.util.ArrayListxÒ^TM^Ça I sizexp w sr *com.progress.recruitment.test.email.Record¨&fnof;ù~&lsaquo;6 I aI bI cI dI idI timexp sq ~ ¥¤sq ~
Ûsq ~ gÒsq ~ 5ásq ~ E.x

It looks like it might contain serialized Java objects, since it contains Java class names. Have you tried reading it as such to see what happens?
Or are you asking how to do that? In which case why not just start with the code in the Java serialization tutorial and go from there?
Or did you not know there was such a tutorial? Google keywords: "java serialization tutorial".
