Reading Data from Buffer

Hi all,
I have a custom RFC which makes use of IDOC_INPUT_BOMMAT to create a BOM.But the BOM is not yet committed and i need to retrieve this data.If i put a break-point after the call to the FM IDOC_INPUT_BOMMAT and at the same time check the database table it's not yet present in the table.We tried all methods but could not succeed.Please let us know if the data can be read through buffers.If so which FM should i use to get this data .. ?
Cheers
Nishanth

Hi,
I don't think you will be able to read the data from buffer. Even if you can find it, getting the right strcutures for the data you are looking for will be very tedious.

How to read data from buffer while validating in sm30

Hi all.
I am doing validations in sm30 by using events.The user is entering the data thru sm30 (multiple records at a time) Before the data gets saved into database table it might be storing in some buffer. Can you pls tell me where this data is buffered before getting saved into database table.Do we have any standard global fields which can hold the data which we entered in sm30 before saving in data base .Thanks in advance.
Kind Regards,

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;

As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));

catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();

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:
private void calcResults(TextArea loanResults, double amount,double interest, int term ) throws IOException {
     DecimalFormat df = new DecimalFormat("$###,###.00");
     NumberFormat formats = new DecimalFormat("#0.00");

     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++)
      month= i+1;

      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");

Reading data from a XML file.

Hi,
I am new user to webdynpro and has the task of reading data from XML file.The file is created using XML form Builder and is stored at a location.But my code gives me the path instead of the content in the data.
The code is :
try
      IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
       com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
// create an ep5 user from the retrieved user
       IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
       IResourceContext context = new ResourceContext(ep5User);
/Specify the path of ur document here./
       RID pathRID = RID.getRID("/documents/70f51182-84c3-2710-ce91-8d5fbfde713d.xml");
       //RID pathRID = RID.getRID("/documents/hol.txt");
       wdContext.currentContextElement().setSetDisp(pathRID.toString());
       IResource resource = ResourceFactory.getInstance().getResource(pathRID, context);
       InputStream in = resource.getContent().getInputStream();
       ByteArrayOutputStream out = new ByteArrayOutputStream();
       byte[] buffer = new byte[4096];
       int bytesread = 0;
       while ((bytesread = in.read(buffer)) != -1)
           out.write(buffer, 0, bytesread);
       String myData = out.toString();
/*myFile will containS the content of the document./
       wdContext.currentContextElement().setSetDisp(myData);
       catch (Exception e)
        // wdContext.currentContextElement().setTextdisp("IO Error:" + e.getMessage());
text data is read from the location but XML data is not read.
Please help me out.

hi SriRam,
For some reasons you are not able to change the value of attribute SetDisp ahich you gave the default value as the path using the following statement
wdContext.currentContextElement().setSetDisp(myData);
Remove that line.First try to open the files using creating new window instance
IWDWindow window =
            wdComponentAPI.getWindowManager().createExternalWindow(
                  "http://<server name>:<port no>/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs"
                        + "/documents/Public Documents/...."
                        + "/"
                        +<name>,
                  "from km repository",
                  false);
      window.open();
Then we can be sure that the error is due to reading data using input stream

Reading Data from CSV file

Hi Guys,
I am trying to read data from a CSV file character by character. Whats the best way to do this? Any examples around?
Thanks
tzaf

Does this mean your file will have multiple lines? And each line would indicate a new record? If so, you should use the BufferedReader and take in each line as a String. Then you can use the StringTokenizer to separate your string into tokens using the comma as your delimiter. From there you can convert the string tokens into whatever form you like, but by default they are already in String form. To make it an Integer I'd use Integer.parseInt().
I will show you some code on how to get the values from your file using the BufferedReader and the StringTokenizer but what you do with those values afterwards I'm going to leave up to you.
File csvfile = new File("myfile.csv");
byte[] fileBuf = new byte[1024];     // buffer for file data
int bytesRead = 0;               // number of bytes read
try
     BufferedReader fileIn = new BufferedReader( new FileReader( csvfile ));
     PrintStream out = new PrintStream( System.out );
     String readLine;     // stores a line from the file as a string
     while( (readLine = fileIn.readLine()) != null )
          StringTokenizer tokens = new StringTokenizer( readLine, ",", false);
          // false means you don't want to count the commas, only the values
          while( tokens.hasMoreTokens() )
               String aValue = tokens.nextToken();
               // ... do what you want with the value
               // ... change to Integer or whatever
               out.println(aValue); // Printing the value to the screen
     fileIn.close();
}Good luck,

Query for reading data in buffer

*Which FM is use to read values from buffer, CRMORDER_READ or CRM_ORDER_READ_OW?*_

Hello
Actually the FM CRM_ORDER_READ invokes FM CRM_ORDER_READ_OW. However if the statement SELECT is raised from these FM and the table in question is flaged as Buffered Allowed, so the DBI will check the buffer before retireve data from the Database.

How to read data from analog input and export it to a file using Components Works

I've made a simple application (Delphi 5 using the activeX) that read data from analog input channel 0. After I read the data, I want to export it to a file using the Components Works on a 6035E NIDAQ. (I'm not using labview and don't want to use it)
How can I do that???
Regards,
Francis

Here's a sample code to do this...
P.S.: If you read only one channel this code won't work.
function MyFunction: Integer;
var
Low, High, i, j, ChannelCount, RowCount: Integer;
Po: P;
begin
//you are reading multiple channel
ChannelCount := VarArrayHighBound(Buffer, 1);
RowCount := VarArrayHighBound(Buffer, 2);
for i := 0 to ChannelCount do begin
for j := 0 to RowCount do begin
WriteToDisk(Buffer[i, j]));
end;
end;
end;

Error 65575: overrun error while reading data from NI 9871

Hello everyone,
I am new here. I configured NI 9871 in RS-485 mode to acquire data from a sensor at the data rate of 8 samples per second. While reading data from sensor, sometimes I got the error 65575: "An overrun error has occurred in the data being read. Ensure that the module Flow Control is configured correctly." I didn't understand the error, how can I fix it, what dose the flow control means.
I will be very thankful if anybody help me to fix this error.
Thanks
Wasif

Hello Wasif,
The error you are getting presents itself when the hardware buffer is full and new data is coming in. Data buffer is 64 bytes. One thing to try is to clear the RX FIFO after every read. Please refer to the following link that talks about the method.

Reading data from mlx90129 rfid tag chip by using spi communication with labview?

Hi,
i have evb90129 evalution board in that mlx90129 chip and external memory (cat25128) and three external sensors are there, i am logging data from chip by using rfid reader it ok i am reading. at the same time i configured spi communication and i am trying to read data i am reading data from internal memory not from external memory i tried but i didnt suceed , now can i use labview to read data from mlx chip and external memory. for spi communication i am using sparkfunction atmega168 microcontroller and also i have spi to usb cable? now can i communicate or i required any devies? is it possible?
thanks in advance,
biji.

I suspect the culprit to be the first parameter to your function actually. Calling another function requires the caller to allocate any buffer with a big enough size for the function to write something into. Allocate that array by using Initialize Array with U8 as type and the correct number as size. Pass this size also as read_length. While your code doesn't make use of this I think the third parameter to your function is either wrong or unnecessary.
As you use it now it is really nothing more than a local stack variable which you could declare inside the fucntion just as well. On the other hand what you probably want to do is have a function prototype like:
extern "C" _declspec(dllexport) unsigned char read_Sensor(unsigned *char read_data, unsigned long read_length, unsigned long *byte_transfered);
But you will have to do some modifications in your C code to support that parameter correctly.
That all said, doing the same in LabVIEW using VISA functions would have been done with about two VISA nodes, no DLL headaches and probably already long ago working.

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,

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 SAP R/3 Class-System

Hello,
first of all sorry when I posted this into the wrong subforum, but I wasn't sure about that. My Question is how to read data from the Classystem I have specified in my ABAP report.
The goal is to read data from my individual class-system as well as data from MM and write them to a table that is to be read by another report. But right now I can't find information about the class system and abap. Maybe you know some tutorials or blogs about right that topic you can suggest?

What class system have you specified in your report?
Normally a class can be used by declaring a variable of type of the class in question, if this class can be instantiated this is. If your class can't be instantiated, but it has only class methods, you can call this method directly.
But there is a lot more to this ABAP Object Oriented Programming, than just this short explanation. Search on SDN for some ABAP OO Tutorials.

Can not read data from URL!

Hello,
I want to read data from URL (http://84.100.130.82:8000/;stream.nsv). But can not do it. Because when try to call function openDataInputStream() shows this error: java.io.IOException: response does not start with HTTP it starts with: ICY. How I can fix this bug?
HttpConnection c = null;
InputStream is = null;
OutputStream os = null;
StringBuffer b = new StringBuffer();
String response,
responseLitle;
c = (HttpConnection)Connector.open(“http://84.100.130.82:8000/;stream.nsv”);
os = c.openOutputStream();
os.flush();
is = c.openDataInputStream(); // ERROR CODE HERE
int ch;
// receive output
while ((ch = is.read()) != -1)
b.append((char) ch);
response = b.toString();Regards, Ramunas

Hi, I�m trying to do the same as above, get MP3 from a Shoutcast server.
I got the same fault ("response does not start with HTTP it starts with: ICY") when I tried to open an HttpConnection as bellow:
============================================
HttpConnection conn = (HttpConnection) Connector.open("http://64.236.34.196/stream/1074");
Then I tried to open a socket connection as bellow:
======================================
SocketConnection conn = (SocketConnection) Connector.open("socket://64.236.34.196:80");
String get = "GET /stream/1074 HTTP/1.1";
DataOutputStream os = conn.openDataOutputStream();
os.writeUTF(get);
InputStream is = conn.openInputStream();
But then I got the following error:
=========================
java.lang.SecurityException: Target port denied to untrusted applications
Could someone help me to find out what is going on?
Thanks a lot!

Hi
If you can convert the excel to a csv format, then it can be simply query from DB Creating Oracle External Tables. Best part is that you may still change the CSV using EXCEL.
Following action Points can be adopt;
*1. Convert Excel File to a csv. File Save as CSV*
*2. Create Oracle Directory* ( This has to be the location of your excel file )
SQL> Create directory mydir as 'C:\testdb'; --- "testdb" is the location folder in win for your excel sheet.
*3. Create the External Table*
SQL> create table my_ext_tab (
Field1 Datatype,
Field2 Datatype,
Field3 Datatype,
Field4 Datatype,
Field5 Datatype
Organization external
(type oracle_loader default directory mydir
access parameters (records delimited by newline fields terminated by ',')
location ('my_ext_tab.csv'))
reject limit 100;
*4. Now you can query the table "my_ext_tab"*
Select * from "my_ext_tab";
Please avoid the reformat the data column inside the spreadsheet (CSV).
