In linux box I want to get data from a named pipe(created using "mkfifo <filename>".
How I can read the incoming data from the named pipe?there are some caveats though: if i remember correctly, when you reach the end of data in a fifo it will look like end-of-file and that may confuse some classes. So your mileage may vary

How to read data from many excel files
I'm aquiring data continusly from several sensors, and every days file name are changed. Data are saved on xls files.
Now, I'd like to read every data from this files and put them in a waveform. How can I concatenate all files and read the values?You probably do not want to use a traditional waveform. LabVIEW has a Waveform Chart which inputs one point at a time. Waveform Graph inputs an array.
I suspect that the data is stored in an array. You need to read the arrays in and build them into larger arrays. If your right click on the build array vi, you can select concantenate which will append one array to the end of the other. When you have built your giant array, just feed it to a waveform graph.
If you need to see some example code, go to the advanced search page. It is at www.ni.com >> support >> advanced search (it is at the botton--click on the words). Enter excel read in the all the words field and search just the example programs. There were for hits.

Reading data from an excel file
Hi,
I want to read data from the excel file and display it in
jsp page. Iam getting the following error:
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con =
DriverManager.getConnection("jdbc:odbc:mydsn","","");
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select * from [holidays$]");
Here i have created the dsn with the name "mydsn". I have the
following data in the mydsn.dsn file:
[ODBC]
DRIVER=Microsoft Excel Driver (*.xls)
UID=admin

DBQ=D:\WorkSpace\Projects\VINET\devl\webroot\jsp\list_of_holidays_2003.xls
thanks in advance
phani.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.

Edited by: Taton on Mar 7, 2009 4:41 PMIt's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.

*Unless you write a bunch of JNI code to replicate what the java.io classes are doing. -
