Read-Write ABF-Files

Hello!I wish to write the program allowing to read and write abf files. For this purpose on a site http://www.moleculardevices.com/home.html has downloaded library dll - Axabffio32.dll. The problem following - how with Call Library Function Node to describe function ABF_ReadOpen:
#include "abffiles.h"BOOL ABF_ReadOpen( char *szFileName, int *phFile, UINT uFlags,ABFFileHeader *pFH, UINT *puMaxSamples,DWORD *pdwMaxEpi, int *pnError );Opens an existing ABF data file for reading. Reads the acquisition parameters from the file header into the passed ABFFileHeader structure.Parameter szFileName Name of data file to open. phFile Pointer to ABF file handle of this file. uFlags Flag to indicate whether file is parameter file or not. pFH Pointer to acquisition parameters read from data file. puMaxSamples Pointer to requested size of data blocks to be returned. pdwMaxEpi Pointer to number of sweeps that exist in the data file. pnError Address of error return code. May be NULL.
The ABF_ReadOpen function opens the data file szFileName, allocates an ABF file handle for it and assigns this number to *phFile. Data is read from the file header into *pFH. If ABF_PARAMFILE is set in uFlags then no further processing is performed, otherwise internal buffers are allocated in preparation for file reading.For ABF_GAPFREEFILE and ABF_VARLENEVENTS files, *puMaxSamples is passed in as a requested maximum size of the blocks of data returned by the ABF_ReadMultiplex and ABF_ReadChannel routines. For all modes, the actual value that will be used is returned in this location.For Event Detected modes, on calling ABF_ReadOpen, the parameter pdwMaxEpi points to a the maximum number of sweeps to read from the file. If it is zero the maximum will be 8192 sweeps, depending on RAM availability. The total number of data blocks of the size returned in *puMaxSamples is returned in *pdwMaxEpi.
I try do it as
int8_t ABF_ReadOpen(CStr *szFileName, int16_t *phFile, uint16_t uFlags, int32_t *pFH, uint16_t *puMaxSamples, int32_t *pdwMaxEpi, int16_t *pnError );
But it's not working.
Thanks.

Hello!I wish to make record abf-files, therefore variants of the program which has sent srikrishnaNF me do not arrange.I have decided not to work with dll, and have found as is written abf a file as bytes. As it is told in the description the data are written in a format "as multiplexed two-byte binary integers". What does it mean? I have written the program which reads out on two bytes from a file and translates them in type single, but I do not find numbers which are written in a file (read this value with OriginLab).

Read/Write Jar files?

This is really a newbie question, but since there's a forum specifically for jar questions I figured it was better to start here and move it to the newbie section if y'all deem it appropriate.
I have written a desktop application using Java 1.4.1 class libraries and intend the application to run on multiple platforms including Mac OS X, Windows XP and Linux. The application works standalone (not yet jarred) on the machine it was developed on, but now it's time to begin figuring out the distribution method.
Right now, the application reads several files from a flat text-file database, allows the user to peruse and display the information in a variety of ways, and gives the user a method to add to the flat-file database as needed. The file is about a megabyte and is excerpted into memory at initialization, then not referred to again unless the user writes additional data. When the user generates new data, write traffic to the file is fairly light, maybe 2-3kbytes per session.
I searched the forums for the best way to handle read/write data files for distribution and so far I haven't found anything that seems relevant, but surely the question must have been asked and answered before - maybe I'm using the wrong keywords?
Anyway, I have three basic questions:
1) Can I both read and write a file that's enclosed in a jar file? Or are files read-only once "jarred"?
2) Assuming I can both read and write a file within my jar file, is reading and rewriting within the jar so inefficient as to make that a non-preferred approach?
3) How do other folks who have a local read/write datafile in a desktop application deal with distribution? Keep the read/write datafile within the jar? Make a copy of it outside the first time the application is run and always read/write the copy outside the jar? Or some other strategy?
Thanks for any suggestions you can give a newbie at the Java game.
Jon

Thanks, that was pretty much what I suspected.
I have several data files and configuration files for this project, so I was trying to make the distribution as clean as possible. At least some of the config information can be hidden in Preferences, but I was struggling with the data files. I'll include the data files in my jar, then unpack them to the user's directory when launched the first time and work with them thereafter in the user's directory.
Enjoy the Dukes!

Why can't I open read/write rules file?

I have followed the Cookbook XML tutorial exactly as prescribed, even down to using all the examples from the 'Completed' folder, but when I try to perform any procedure such as generating a EDD or reading an XML instance (the ColorDoc.xml example) I get the following in the log file:
Could not open the read/write rules file
(App\ChapterReadWriteRules)
Make sure you have read access to the file and that
the file is not already in use.
Using XP and Framemaker 7.
Its a real blocker this proble. Have tries unsetting the XP Read-only folder property on all the folders in the heirarchy but XP won't let me do that. Very grateful if anyone could help me over this problem.

What is the path you mentioned the structapps.fm file for read/write rules
It should be full file path for read/write rules(including extension of file). Otherwise there is possibility of throwing the error you mentioned.
Would it be possible to paste your XML application defined in your structapps.fm file??
Thanks

Lion server file sharing issue with windows API read/write ini file (GetPrivateProfileString)

Hello,
I try to config lion server as file server for a windows application we use at work. All other computers are windows 7 or XP, lion server is the only mac. I choose lion server because it's size, quality and personal love of apple products.
10.7.2 lion server's samba file sharing works almost perfectly with all my windows machines, I can copy, delete, modify any text files or office files without any issue, but the most important windows application for my business doesn't work with samba file sharing. After some digging, I found it is because windows program can't read or write INI file stored on lion share. Windows API GetPrivateProfileString always returns empty if the INI file is store on lion share.
You can download a small application for read/write windows INI file from codeproject.com to test this problem:
http://www.codeproject.com/KB/files/ini.aspx
I can open/edit the in file using any text editor without any problem. The only problem is with those windows APIs. ACL is turned on for my lion share and assigned "delete" rights to samba users.
I install samba3 on the same server; it works perfectly with windows API. My windows program also works. Looks like there is something wrong with lion server's sambax.
I'd prefer to use built-in samba even I have samba3 working. Built-in samba is very immature right now, but considered how young it is, I will give apple some time to make it mature.
Does anyone have same issue or knows how to fix it?
Thanks,
Michael.

All the memory is fine. The server rarely if ever goes down when there are only around 10-12 users connected. When there are 20+ users connected and working heavily it goes down often. When I say working heavily, I mean they are transferring huge files to the SAN (100GB+), sometimes 5 at a time per user, and there are a bunch of others who are reading large video files at a minimum of 220MB/sec from the SAN.
Though this worked on Snow Leopard without any issues, Lion just doesn't seem to be able to handle it. The odd thing is, on Snow Leopard there was only a single 1GB ethernet connection to a NAS system, whereas with Lion we have a much more powerful machine with a 6-port 10GB ethernet card and a 4 lane 8GB fiber card to a true SAN. You would think that the newer scenario with Lion would handle far more users with ease.
So far, very disappointing with regards to Lion's file serving performance.

Read/Write App Files Under Limited User Account

Hi All,
My desktop app is intended for Windows only. I'm writing files to the hard disk to store app specific configuration.
The applications main data source is a ZIp file that consists several XML files. The user can store this ZIP anywehre they like and the application will extract the necessary files to a temp dir so that it can read in data.
When logged into a PC as either an Administrator or Power User, I am able to read write my config files and extract XML files from the ZIP with no problem.
When logged in as a user with "limited" access, I can only read and write the config files. But when I go to extract any XML files from the ZIP, it seem to get denied due to insufficient permissions.
The working directory for storeing all these files is: C:\Documents and Settings\<USER NAME>\Application Data\<MY APP>\
Don't users with limited access have full read/write permissions to their own home directory?
If not, what can be done to give them full read write access? Is there perhaps some other location I should be using?
Also, would code signing from some place like Verisign do any good?
I'm targeting Windows 2000/XP.
Thanks in advance.
Regards,
Jim

You can also access the user folder through the registry:
     public static final String APP_DATA_FOLDER_CMD = REG_QUERY_UTIL
          + "\"HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\"
          + "Explorer\\Shell Folders\" /v AppData";
      * Gets the current user Application Data folder path defined in the
      * registry.
      * @return The current user Application Data folder path.
     public static String getCurrentUserAppDataFolderPath()
          return queryREG_SZ(APP_DATA_FOLDER_CMD);
      * Performs the query in the registry for the specified value type.
      * @param queryString The query to be performed.
      * @param valueType The value type.
      * @return The value data for the specified value name in the registry.
     public static String queryREG_SZ(String queryString, String valueType)
          try
               Process process = Runtime.getRuntime().exec(queryString);
               StreamReader reader = new StreamReader(process.getInputStream());
               reader.start();
               process.waitFor();
               reader.join();
               String result = reader.getResult();
               int p = result.indexOf("REG_SZ");
               if (p == -1)
                    return null;
               return result.substring(p + valueType.length()).trim();
          catch (Exception e)
               return null;
     }This will get you the user directory from the registry. However, my issue is
that the value returned was:
C:\Documents and Settings\<USER NAME>\Application Data
Which is great, but that folder didn't exists on my computer. I cannot find
any documentation to say why it would be there. Except I had no Application
Data folders under any user. I have XP.
So when running the program on one computer, I had no valid folder to write
to and it wouldn't let me create it. Said the <USER NAME> folder could not
be written to. canWrite() returned false and the directory could not be
created.
On another computer, I had the Application Data folder, the canWrite()
returned false, yet I was able to create a folder and file inside.
I checked the default <ALL USERS> directory and the Application Data folder
did not exist there.
I don't understand how I am supposed to work around it...
If the folder doesn't exist, I need to be able to create it, whether it's in the
<ALL USER> or <USER NAME> folder.
I guess I am counting on the canWrite() to be accurate. Yet it appears that
I cannot rely on the canWrite() since a false was returned. I wrote!!
So confused ... need to be able to write to this folder on any computer...
Help!!

Unable to read/write Windows files on mac anymore

Today, out of much extreme panick as of a false alarm, i had installed MacFUSE, an application used so you can read and write windows files on your mac side. What i didn't know is that i already had NTFS-3G, one which could already do that. I uninstalled MacFUSE instantly (removed pane from system preferences), now i still can't see windows mounted on my mac desktop. When i boot up, i get an error; below. If i choose to manually mount it from the disk utility i get the same error. I'm not sure where to post this type of stuff since it's not really apple related but it's worth a shot.

I've had that same issue with NTFS-3G and Fuse. I ended up getting Paragon NTFS for Mac. Its about 20 bucks, but it works great. IMHO, this is a feature Apple should build into OS X especially since they have a feature such as Boot Camp

Read/Write text files in LabVIEW

We have developed an instrument control and data acquisition system for a mass spectrometer using LabVIEW FPGA. Currently we have 6 counters on the FPGA, counting for 1 second intervals and transferring data to the host using a FIFO.
The data, as a local variable, is used in several different parallel loops on the host. One of these is coded to write the data to a text file. Unfortunately everything we have tried has failed. It is proving impossible using either the write to file VI provided with labVIEW, or to use the Open file, write and close file utilities. Each attempt has failed. Yet when running a dummy code we can write to files. The dummy code consists of 6 random number generators running in one loop and the write to file VI in a second loop. The random numbers are transferred across the loops as local variables.
Can anyone offer any advice as to what we might be doing wrong. We're beginning to feel as though we are banging our heads against a brick wall and getting very frustrated.
Many thanks in advance for any suggestions.

Hi Paul,
you neither say, what is failing nor do you show any code... How should we help then?
"impossible using ... the write to file VI"
Well, usually they work just fine.
"Each attempt has failed."
In which way? Error number given? Did you use the debuging tools, like probing, breakpoints and highlighting?
"as local variables."
It seems you're not properly do program "real" LabVIEW code

Possible to read/ write word files using Java?

I'm planning to write a Java application that can read an MS word document, extract something (including mathematics equations created with the equation editor) from the document and write it to another word document.
Is it possible to do this?
Can anyone give me some idea?
Any idea is much appreciated :)

I think I may have misunderstood your question, but in case I didn't and you find this helpful, following is the code to read a word doc, replace certain strings, then write it out as a new doc.
import java.io.*;
public class Copy {
     public static String endResult;
     public static void main(String[] args) {
          String oldAuthor = "Samuel Foote";
          String newAuthor = "New Author";
          String oldDate = "1720-1777";
          String newDate = "1975 -- ";
      try {
          File inputFile = new File("C:\\document.doc");
          BufferedReader input = null;
          input = new BufferedReader(new FileReader(inputFile));
          StringBuffer contents = new StringBuffer();
          String line = null;
          while ((line = input.readLine()) != null){
               contents.append(line);
               contents.append(System.getProperty("line.separator"));
          String text = contents.toString();
//     Replace the author and the dates
          Copy y = new Copy();
          y.replace(text, oldAuthor, newAuthor);
          text = endResult;
          y.replace(text, oldDate, newDate);
//     Copy the new, improved text to another file     //
          Copy z = new Copy();
          z.finalReplace(text);
          input.close();
     catch (FileNotFoundException ex) {
          ex.printStackTrace();
     catch (IOException ex){
          ex.printStackTrace();
     String replace(String text, String oldSubstring, String newSubstring) {
//          Search the text for a string, then replace it //
          int fromIndex = 0;
          int e = 0;
          StringBuffer sb = new StringBuffer();
          while ((e = text.indexOf(oldSubstring, fromIndex)) >= 0) {
               sb.append(text.substring(fromIndex, e));
               sb.append(newSubstring);
               fromIndex = e + oldSubstring.length();
          sb.append(text.substring(fromIndex));
          endResult = sb.toString();
          System.out.println("final string = " + sb);
          return sb.toString();
     String finalReplace (String args) throws IOException {
//          Move the altered text to a new file //
          File outputFile = new File("C:\\copied document.doc");
          FileWriter out = new FileWriter(outputFile);
          Writer output = null;
          try {
               output = new BufferedWriter(new FileWriter(outputFile));
               output.write(endResult);
          finally {

Read & write lvm files

Hi All,
I am plotting one parameter against two parameters on XY Graph. I need to send this graph along with 4 numerics & 1 string data captured during the testing for printing. So I just thought of saving this as LVM file into a location & filename of my choice & read back for printing after the testing is over.
XY Graph requires cluster of 2 elements(one is X array, one is Y array) for plotting. I tried writing only graph part alone to lvm file by builiding an array. But when I tried to read back this, it is not either reporting any error or showing the graph on the indicator.
Hope someone can suggest me how to do.
Thanks

How to read/write .CSV file into CLOB column in a table of Oracle 10g

I have a requirement which is nothing but a table has two column
create table emp_data (empid number, report clob)
Here REPORT column is CLOB data type which used to load the data from the .csv file.
The requirement here is
1) How to load data from .CSV file into CLOB column along with empid using DBMS_lob utility
2) How to read report columns which should return all the columns present in the .CSV file (dynamically because every csv file may have different number of columns) along with the primariy key empid).
eg: empid report_field1 report_field2
1 x y
Any help would be appreciated.

If I understand you right, you want each row in your table to contain an emp_id and the complete text of a multi-record .csv file.
It's not clear how you relate emp_id to the appropriate file to be read. Is the emp_id stored in the csv file?
To read the file, you can use functions from [UTL_FILE|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_file.htm#BABGGEDF] (as long as the file is in a directory accessible to the Oracle server):
declare
    lt_report_clob CLOB;
    l_max_line_length integer := 1024;   -- set as high as the longest line in your file
    l_infile UTL_FILE.file_type;
    l_buffer varchar2(1024);
    l_emp_id report_table.emp_id%type := 123; -- not clear where emp_id comes from
    l_filename varchar2(200) := 'my_file_name.csv';   -- get this from somewhere
begin
   -- open the file; we assume an Oracle directory has already been created
    l_infile := utl_file.fopen('CSV_DIRECTORY', l_filename, 'r', l_max_line_length);
    -- initialise the empty clob
    dbms_lob.createtemporary(lt_report_clob, TRUE, DBMS_LOB.session);
    loop
      begin
         utl_file.get_line(l_infile, l_buffer);
         dbms_lob.append(lt_report_clob, l_buffer);
      exception
         when no_data_found then
             exit;
      end;
    end loop;
    insert into report_table (emp_id, report)
    values (l_emp_id, lt_report_clob);
    -- free the temporary lob
    dbms_lob.freetemporary(lt_report_clob);
   -- close the file
   UTL_FILE.fclose(l_infile);
end;This simple line-by-line approach is easy to understand, and gives you an opportunity (if you want) to take each line in the file and transform it (for example, you could transform it into a nested table, or into XML). However it can be rather slow if there are many records in the csv file - the lob_append operation is not particularly efficient. I was able to improve the efficiency by caching the lines in a VARCHAR2 up to a maximum cache size, and only then appending to the LOB - see [three posts on my blog|http://preferisco.blogspot.com/search/label/lob].
There is at least one other possibility:
- you could use [DBMS_LOB.loadclobfromfile|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i998978]. I've not tried this before myself, but I think the procedure is described [here in the 9i docs|http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96591/adl12bfl.htm#879711]. This is likely to be faster than UTL_FILE (because it is all happening in the underlying DBMS_LOB package, possibly in a native way).
That's all for now. I haven't yet answered your question on how to report data back out of the CLOB. I would like to know how you associate employees with files; what happens if there is > 1 file per employee, etc.
HTH
Regards Nigel
