DIADEM is not reading data into channels
Hi
I am trying to read a tdms file into DIadem through data Navigation.This conatins 12 columns of data.But when it is loaded it creates large number of channels with lengths (arb~200).I tried to create the data pluggin but the small windows are showing unidetified symbols.Is this due to any setting is not set properly
I assume that the file contains a lot more columns/channels than you thought.
This might habben because you created a new groups every time you wrote a new chunk
instead of appending to an existing one
group1.mychannel
group2.mychannel
will result in two channels.
Could you make sure your write code does append instead of create.

Urgent help on reading data into ByteBuffer
Hi,
I am trying to read data into ByteBuffer using SocketChannel.
The following code working fine but the problem is with ByteBuffer size.
The data varies from request to request .
How do I read data into ByteBuffer with out specifing size .
The problem with size is some records has more than 500 bytes and some are less than 500 bytes.
I want to read all the data .. ( even if it has more than 500 bytes ..)
How do i solve this problem ..
Is there any way to read data dynamically from socket channel ...
Any help on this please ...
The data I have to read is in the following format ..
XXX ... yyyyy
AAA
BBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDd
etc ...
Here is my Code:
public ByteBuffer getResponse(byte[] request) throws Exception {
int lenth = 500;
InetSocketAddress isa = new InetSocketAddress("ip", port);
SocketChannel channel = SocketChannel.open(isa);
ByteBuffer requestBuffer = ByteBuffer.wrap(request);
channel.write(requestBuffer);
ByteBuffer responseByteBuffer = ByteBuffer.allocate(length);
int num = 0;
while (num == 0 ) {
responseByteBuffer.rewind();
num = channel.read(responseByteBuffer);
channel.close();
return responseByteBuffer;
Thanks.Two possible solutions
1. Read in as many bytes as you can until you hit the EOS OR you fill the byte buffer. If you fill the buffer (try checking for BufferUnderFlowException), you could move the read bytes into a dynamically allocated memory Collection such as an ArrayList. When you hit the EOF, you could then do whatever else you need to do from then on.
2. I use this option: Implement a site local protocol for transmitting data. Provide a header first containing 2 ints (compressed size, uncompressed size - so you can also use compression when sending), and send the remainder as a payload.
Therefore
Read in the header first (always 8 bytes)
Then extract those integer values. They will tell you how much is being sent. Set you byte buffer for the payload to be the correct size for this transmission.
Reset and wait for next connection -

sudharsan.Hi,
The select command is the most fundamental function of writing ABAP programs allowing the retrieval of data from SAP database tables.
Try filling the 3rd internal table with Loop ... Endloop.
Loop at t_tcurr.
Read table t_rabr with key field1 = t_tcurr-field1.
If sy-subrc = 0.
Move t_tcurr-field1 = itab_final-field1.
Move t_tcurr-field2 = itab_final-field2.
Move t_rabr -field3 = itab_final-field3.
Move t_rabr -field4 = itab_final-field4.
Append itab_final.
Endloop.
Hope this helps you.

Can not extract data into BW from SQL SERVER
Dear All,
I meet a problem to extract data from database(MS SQL Server 2000(sp3)) into BW now and can not extract data into BW ODS, even PSA, In the monitor, display yellow light(0 from 0 record), detail message just display message "data request arranged" "confirmed with: confirmation" in requests(message) step; "missing message: request received" in extract (message) step; "no data" in processing(data packet) step and so on. but in fact, there are two records in my database test table and DB connection is OK. Even I can extract data from another test oracle database into BW ODS successfully.
Our BW system has two BW applicaton server and use oracle database. the one application server locates on IBM AIX host. the another one locates on one NT server. the application server on NT server is used for data extration from MS SQL SERVER database into BW oracle database. and MS SQL SERVER and NT platform application server locate on same one host. DBSL was installed on the NT application server already. and DB connector also was created successfully for MS SQL SERVER and datasource also was generated. DBSL type is Kernel640-WIN-IA32bit-unicode. my BW system is ECC5.0/UNICODE/ORACLE. all table/view/field name of MS SQL server is upcase and have not any specific character. for example: ZDEMO etc.
wait your help.
Thanks in advance.

when I was talking on phone, suddenly the phone was switched off.
i tried to switch it on but it gave the message....connect to itunes for set up.
when I connected it to itunes...it gave the message, itunes can not read data from this iphone, restore it to factory settings. It also said while restoring ypu will lose all media data but you can restore the contacts.
I restored the factory settings....the phone was on recovery mode...it was verified by itunes and all that..but in the end it again said that iphone has some problem and can not function right now.
after that when ever i connect it with itunes, it gives the message, it can not activate the iphone further, try again later or contact customer service.
What to do now?????? Customer service people say..it is hardware problemIf it's a hardware problem, then the phone will need to be replaced.
There is no magic that can fix a hardware problem. -
Server Socket does not read data input stream
Hi all,
I am very newbie to Java Network programming with sockets and multi-threading.
But I am obliged to develop a chat system written in Applets which can be placed on the website and used by visitors who come to my website.
In order to understand this, I have tested a basic web chat program I downloaded from the Internet which use sockets and multi-threadings. The program work fine, no bugs at all at both compilation and run time. I noticed that all three streams for Client side (i.e. first one is input stream used receiving data from User; the second one is socket input stream used for receiving data from Server socket, and the third is socket output stream used for writing data to server socket) were established. And the same, two socket streams (input & output) for Server side were also connected when running program giving right port number and IP address of the server.
The problem is both server and client sockets do not read data using the following stream classes:
1. DataStreamInput: I use input.readUTF() method
2. or BufferedReader: I use input.readLine() method
The example of the codes are below:
private BufferedReader input = null;
private PrintWriter output = null;
private Socket socket = null;
public void open() throws IOException
{ input = new BufferedReader(new
InputStreamReader(socket.getInputStream()));
System.out.println("Server socket input stream was created, and");
output = new PrintWriter(socket.getOutputStream());
System.out.println("Server socket output stream was created");
public void run()
{ System.out.println("Server Thread " + clientPort + " running.");
while (true)
{ try
System.out.println("Server is reading data from Client, wait...");
String fromClient = input.readLine();
System.out.println("Server received a message on " + clientPort + ".");
catch(IOException ioe)
{ System.out.println(clientPort + " ERROR reading: " + ioe.getMessage());
server.remove(clientPort);
stop();
The problem is at the line: String fromClient = input.readLine(); in the run() method? What is wrong with the codes above?
Note: I also try to use original codes which use readUTF() method in DataStreamInput class instead using readLine() in BufferedReader. Both methods dont read data from inputstream socket?
I very appreciate any help/advice from experienced developers.
Best regardsHi,
Yes. The readLine() method hangs! After the test, the execuation of the program is stopped at the line of readLine() method; it does not pass it?
There is no problem with writing to Server socket. After the test, the program pass through flush() method. Here is the code for writing to sever socket within ChatClient (client side socket) class:
private BufferedReader input = null;
private PrintWriter output = null;
public ChatClient(String serverName, int serverPort)
{ System.out.println("Establishing connection. Please wait ...");
try
{ socket = new Socket(serverName, serverPort);
System.out.println("Connected: " + socket);
start();
catch(UnknownHostException uhe)
{ System.out.println("Host unknown: " + uhe.getMessage()); }
catch(IOException ioe)
{ System.out.println("Unexpected exception: " + ioe.getMessage()); }
public void start() throws IOException
{ input = new BufferedReader (new
InputStreamReader(System.in));
System.out.println("Client User input stream was created,");
output = new PrintWriter(socket.getOutputStream());
System.out.println("Client Socket output stream was established, and");
if (thread == null)
{ client = new ChatClientThread(this, socket);
thread = new Thread(this);
thread.start();
public void run()
while (thread != null) {
String fromUser;
try{
while((fromUser = input.readLine())!= null)
System.out.println("Client wasreading a data from User, and");
output.println(fromUser);
output.flush();
System.out.println("Client has written a data to Server");
catch(IOException ioe)
{ System.out.println("Sending to server error: " + ioe.getMessage());
stop();
etc.
Here is a piece of codes for reading data from the Client Socket in the ChatServer Class (Server Side socket):
public void run()
{ System.out.println("Server Thread " + clientPort + " running.");
while (true)
{ try
{ //server.handle(clientPort, input.readLine());
System.out.println("Server is reading data from Client, wait...");
String fromUser = input.readLine();
//while((fromUser = input.readLine()) != null)
System.out.println("Server received a message on " + clientPort + ".");
catch(IOException ioe)
{ System.out.println(clientPort + " ERROR reading: " + ioe.getMessage());
server.remove(clientPort);
stop();
etc. Please advice why the readLine() method hangs; does not read data from the input stream received from the CLIENT? -

DVDRAM will not read data disks
I have a A215-S4697 with a HL-DT-ST GSA T20n DVDRAM. The drive will read CD and DVD audio and video disks. It will not read data disks. The driver says it is a CD-ROM. Is there a better driver I need? Has anyone had the same problem and found a solution?
ThanksCory K wrote:
Is the file open in Excel, or is it open because your VI is writing data to it somewhere in your code?
If the latter case is true, you can use a semaphore to ensure that a read and write operation are not trying to occur simultaneously.
The file is open in Excel. -
Reading Data into a PDF form with cfpdfform and cfpdfformparam
I have been trying to read data from a query into a PDF form. I have the application setup to generate a new pdf file for every record in the database table which is working perfectly, but when I try to have the application pre-populate the form fields in the pdf form they remain empty. I have included a snippet of the code that creates the PDF documents. I am using Adobe LiveCycle Designer 8.0 to create the PDF form.
Snippet Example:
<cfoutput query="renewals">
<cfset new_file = "#reportnumber#.pdf" />
<cfpdfform action = "populate" source = "beta.pdf" destination = "#new_file#">
<cfpdfformparam name="Legal_Contact_Name" value="#LegalContactName#">
</cfpdfform>
<cfpdf action = "write" source = "#new_file#" destination = "#new_file#" flatten = "yes" overwrite = "yes" />
</cfoutput>
All help is greatly appreciated...I'm just glad I might be of any help.
First, make sure the image is embeded as a base64 encoded string in the xml structure you're working with on your form you've built in LiveCycle Designer.
I do this by reading the image file and outputing its content as a base64 string:
<cffile action="read" file="#expandPath('Path/to/your/image/file/BC.TIF')#" variable="imgObj" />
<img>#toBase64(imgObj)#</img>
Your PDF form should be bound to this 'img' field from your xml structure in LiveCycle Designer.
This works perfectly and the image from the xml is indeed displayed in the PDF form generated with cfpdf.
BUT, from the moment you convert the pdf form to static pdf document, the image will be gone - the dynamic text remains.
Note: I never further investigated why the image disapears once the pdf form is converted to 'static' pdf. Thinking about it now, it might have been an incoding issue. The toBase64() function in ColdFusion has an optional "Encoding" argument, may be by playing with the encoding the image might finally 'survive' the conversion to static pdf.
Good luck.
note: this will populate the pdf form from your xml structure in ColdFusion.
<cfpdfform action="populate" source="/path/to/LiveCycle_generated_templateForm.pdf" xmldata="#your_xml_structure#" destination="/path/to/result.pdf" overwrite="yes" /> -
Numeric Keypad does not enter data into Excel
Is there a way to turn on/off the numeric keypad for the imac intel based apple computer when using Microsoft Excel?
I want to enter numeric data into the cells of a spreadsheet in the Excel program, but I can not figure out how to get the numeric keypad to work to do this. It will only work as a directional keypad, moving the active cell left or right, or shoot to the end of the spreadsheet. Consequently I forced to use the use the row of numbers above the keyboard (which is also the row of numbers below the function keys) to enter data.
Strangely, the numeric keypad will enter data with other programs, such as Word or when entering data into an online page.
I have searched Apple help without success.Make sure that NumLock has not been engaged. To toggle that on and off, press Shift-Clear ("Clear" is the key immediately above the 7 on the keypad).

Streaming data to disk, need help reading data into Power Spectrum/Octave vi
I'm streaming data to disk in one loop, however once this finishes I'd like to read the data into power spectrum vi/Octave analysis vi in another loop. The data from the read vi is a string and power spectrum vi needs 1d waveform. Does anyone have experience with this process?
From your general description, I gather you are streaming to a text based file (comma or tab separated spreadsheet format) and would like to analyse this data with a power spectrum or octave analysis when you finish. Since you are streaming, I assume you have a lot of data. Do you have more than one channel?
In any case, you have two simple options (and lots of complex ones). You can either read the data back from disk and convert it to a 1D array (try the Read From Spreadsheet File.vi - will get a 2D array, take the first column or the column of your choice if you have more than one channel) or you can use the Spreadsheet String to Array primitive to create an array from your text data before you save it to disk.
If your data rate is slow enough, you can analyze as you acquire and store.
Taking your data as text is very inefficient. What you really want to do is read the data as binary, use that for your analysis, and use something like the Write to Spreadsheet File.vi to save text data to disk.

After WLS10.3 migration getBinaryStream in Oracle.sql.BLOB not reading data
Please some one help me. After the 10.3 migration, the values in CSV file(as BLOB in DATABASE) is not read by getBinaryStream method. It returns 0. It was working before. Please find below the code:
import oracle.jdbc.OracleResultSet;
import oracle.sql.BLOB;
public InputStream RetriveISfromBlob(int batchid)
BLOB blob;
InputStream instream=null;
try
Statement stmt = connection.createStatement ();
ResultSet resSet = stmt.executeQuery
("SELECT content FROM file_upload WHERE batch_id="+batchid);
resSet.next();
System.out.println("after query");
/*Get the BLOB locator.*/
blob = ((OracleResultSet)resSet).getBLOB(1);
/*get the blob's outputstream
any data read from this stream comes from the BLOB*/
instream = blob.getBinaryStream();
Below is code from Another class which call the above method RetriveISfromBlob:
InputStream inputstream = fileDataDAO.RetriveISfromBlob(batchId);
System.out.println("afterfileread");
CommaFileInputStream reader = new CommaFileInputStream(inputstream);
reader.setIgnoreFirstLine(true);
CommaRecord comma = reader.getCommaRecord();
System.out.println("Number of records -" + comma.size()); /This returns o but CSV file has lot of datas
NOTE: When I use Ojdbc14.jar only the above code returns 0. When i use Ojdbc_6g.jar it throws NULL POINTER EXCEPTION because the code was written like import oracle.jdbc.driver.OracleResultSet; But in all cases the data in BLOB was not read

OOK Burst Demodulator Not Reading Data
I am using the OOK Burst Demodulator with the OOK Modulator vi found on this forum. When I try running the OOK Burst Demodulator, avaiable from the RF Fixed Point Examples, I am getting Error -50400. It looks as though the data is not coming through across the DMA. My problem is probably that data is not being demodulated correct.
On the transmit side, I am using the OOK Modulator example. Before, I was getting FIFO underflow issues because there was not enough data being written to the DAC. Therefore, I modified the VI to loop the data back into the FIFO. Therefore, it sends it's sync bits and data bits over and over again. Will this work with the OOK demodulator? Any suggestions on OOK modulation and demodulation would be appreciated. Thanks!
PatrickHi Patrick,
Try out the attached OOK modulator with the fixed point demodulator.
Let me know if this does not work.
