Reading dynamically changing file
Hi all
I have a text file which is dynamic in nature, ie, every 1-30 minute(s) a line is appended to it.
I would be grateful if anyone helps me (may be with some sample code/link) in how I can get a notification regarding when the line is appended and how to get the last appended line(s).
Thanks in advance
Anjan
Run a thread to check the file every half hour or however often you like, then use java.io.File.lastModified(). Compare this long (representing a time) to the last time you checked it. If the new time is greater (more recent) than the last time you checked, the file has changed.

Selecting dynamically changing file
Hi everyone
I'm creating a script that will copy the currently selected track from itunes to the desktop and import into iMovie. The following is what I have thus far:
-- check if itunes is open
tell application "Finder"
if (get name of every process whose visible is true) ¬
contains "iTunes" then
my convertSong()
else
display dialog ¬
"You have not selected a song from iTunes!" buttons ¬
"Cancel" default button 1 giving up after 10
end if
end tell
on convertSong()
-- dupe selected track
tell application "iTunes"
if selection is not {} then
set _location to get location of selection
else
display dialog "You have not selected a song from iTunes!" buttons ¬
"Cancel" default button 1 giving up after 10
end if
end tell
set _theSong to (choose file with prompt "Choose Song" default location _location)
tell application "Finder" to duplicate _theSong to "Macintosh HD:Users:OAC:Desktop"
delay 2
-- create new movie, import song from desktop.
tell application "iMovie HD"
try
open
end try
activate
tell application "System Events"
keystroke "n" using {command down}
delay 1
keystroke "iMovieSong"
delay 1
tell process "iMovie HD"
click button "Create" of window "Create Project"
end tell
delay 15
-- brings up the Import dialog from iMovie menu
keystroke "i" using {command down, shift down}
-- select file statements here
end tell
end tell
end convertSong
the problem is I don't know how to reference the duplicated song (which will be changing periodically). What kinds of statements will work in this situation?
thanks!Ahh, that's one of the vagaries of the Finder - it has its own unique way of referencing files.
There are two ways around it, one is to tell the Finder to open the file with a specific application:
tell application "Finder"
set theDupeFile to duplicate _theSong to "Macintosh HD:Users:OAC:Desktop"
open theDupeFile using application "iMovie"
end tell
the other is to coerce the result of the duplicate command to an alias, the universal file reference:
tell application "Finder" to set theDupeFile to duplicate _theSong to "Macintosh HD:Users:OAC:Desktop" as alias
That simple as alias on the end coerces the Finder reference to an alias which any other application should be able to handle. -
Grant an account rights to read and modify files in all Redirected Documents folders?
We have set up redirected Documents folder with the default recommended permissions that does not grant Administrators any access to the folders. If an administrator needs access to a folder, they take ownership of the folder, grants themselves permissions
and does whatever they need to do with the folder such as delete it or give access to a new person. This is rarely needed so it is not a big deal.
However, we now need to import everyone's Outlook PSTs (stored in their redirected MyDoc's so they are backed up) into their new Exchange Archive mailboxes. We will also need to be able to verify all PSTs are gone from the file server
once the contents are imported into their archive mailbox. We also need to be able to run reports showing which users are storing music and video files in their folders and how much.
When I tried to run Windirstat against the share containing the redirected MyDocs folders to see what file types where taking up space, I got very incomplete results even with using psexec running as system account due to inadequate permissions on the user's
folders.
We also need the PST Capture Tool to have rights to read into their documents folders and move any psts found into the users archive mailbox.
Rather than having to go to each user's redirected documents fiolder one by one and take ownership to change permissions, is there a more efficient way to have an account running the PST Capture Tool and WindirStat have access to read and change files in
the user's redirected documents folders?
I thought of just removing the option in the GPO that says "Grant the user exclusive rights to My Documents," but I don't think that will work on pre-existing
folders that already have permissions set.Hi,
Based on my research, if you already have a bunch of existing redirected My Documents folders set up with the
Grant the user exclusive rights to My Documents check box selected, the only documented way to regain access to the folders is to take ownership of each individual folder and manually edit the permissions to give the Administrators group full
control.
We can use powershell script to help regain access to the folders, for more details, please go through the below link:

I am facing the same problem. Please help me out. I just want to read a PDF file as bytes from one location and write it as another pdf file in some other location with a diolog box prompting to open or save in the location where we want.
I executed the following code:
try{
File report =new File(location);
BufferedInputStream in=new BufferedInputStream(new FileInputStream(report));
response.setContentType("application/x-download");
response.setHeader("Content-Disposition", "attachment; filename=" + report.getName());
OutputStream outs = response.getOutputStream();
int readlen;
byte buffer[] = new byte[ 256 ];
while( (readlen = in.read( buffer )) != -1 )
outs.write( buffer, 0, readlen );
outs.flush();
outs.close();
in.close();
response.setStatus(HttpServletResponse.SC_OK);
} catch (FileNotFoundException fileNotFoundException) {
PrintWriter out= response.getWriter();
out.print("<center><Font color = 'RED'><b>"+PxDSLUtils.getApplicationProperty("label.error.CTM_E017")+"</b></Font></center>");
Though it prompts with open, save dialog box when i try to open directly or when i save it some where locally and then open it i am getting the following message " File is repaired ot damaged.Operation failed." Any idea about what can be done??? Its very urgent.Please suggest.
I am not convetin to string just reading and writng as bytes itself.

Is there any way to bypass changing the init file to make a dynamic change?
I have to make a change for archiving, and I can't bounce the db right now.
10.2.0.3, HPUX itanium
changes that need to be made...
log_archive_config DG_CONFIG=(peregrine,swesc)
log_archive_dest_state_2 = DEFER
fal_client peregrine
fal_server swesc
I don't really want to just issue these at the command line unknowing if they would do as I want or cause adverse affects.
Is it possible to just rip the command, and update the file too? command line causing immediate change, and init file change will allow for keeping it when restarted...
Thanksalter system set <parameter> = <value>;defaults to memory assuming that they are immediately modifiable
otherwise
alter system set <parameter> = <value> scope = memory;should do the trick as well. You probably want to use a spfile that way you can do both at the same time:
alter system set <parameter> = <value> scope = both; -
I can no longer read my adobe files in my documents, where I could before, what's changed? Help!
I could previously view these files with no problem, I have all the latest versions of adobe and plug in installed, when I try and open a file it tells me adobe reader could not open the file I am trying to open because it is either not a supported file type or the file has been damaged. I don't understand what is going on and need access to these files. Can anyone help please?
I think you need to change your Windows Explorer settings to show the file extensions, then you can clearly see what file types you have.
Those with .doc / .docx extensions should show the blue Word icon.
Those with .pdf extensions should show the red Adobe Reader icon.
Those that do not need to fix the file association; see http://windows.microsoft.com/en-us/windows/change-file-open-program -

Can I change the file path that itunes reads my music files from?
I have about 65000 music files that i have transferrd from my external to a new laptop internal HD.
I have organised the folders myself as I use a PC and do not want itunes to organise the folders because when I'm searching through music on windows it is sorted out by artists/albums with 'the...(eg The Beatles)' under 'T' instead of 'B'.
Long story short.... Is there any way that I can keep my itunes library as it is on the external HD and copy it to the new laptops C drive, keep all the info (playlists etc) and still have the same folder structure as on the external HD?
Or, is there any way of making windows sort things in alphabetical order like it is in itunes (eliminating the 'the' issue)?The files that weren't inside the media folder on the original machine need to be copied over to exactly the same paths as they had on the source machine. See this thread for an ongoing discussion of a similar problem. See also this post on migrating the iTunes library.

Java mapping - for reading the binary file contents and changing filename
Hi,
I have already gone through the various bolgs and threads and have not been able to find a solution to my problem.
One blog did give some idea but did not help- "JAAPPING", an alternate way of reading a CSV file
I am not very good in java but have been trying some out recently to fulfill the interface requirements.
I would really appreciate if you could help am I am giving below the detailed scenario below.
Part 1- working fine - The incoming file looks like:
:20:STMEMU096868DUBE
:25:001180256210
:28C:00371/00001
:60F:C090617AED742136,92

26MAY2009 TO 25JUN2009
:62F:C090630AED742171,19
:64:C090630AED742171,19
The file name as received is:TCDE.BLQSAM.SAEA2682.C0084025.A9G24T58.20090724195908
This file without any conversion is placed on XI server dircetory folder.
Part 2 - need to develop
The file should now be renamed according to the incoming value in 2nd line - specifically the 12 digit value 001180256210 and placed on the R/3 dircetory folder.
The new file name in the above example should be:
AC_NO_001180256210_datetime
The module for the above was created and the last time I checked it was working.
However, when I wanted to do final testing in Dev and move the changes further, the module has seemed to have stopped working so I need an alternate solution fast.
I was thinking of doing the Java mapping as I will be more in control as to what is going on thereby reducing the dependency.
There is no need to create any target xml structure as the file as it is needs to be placed in the target folder with a new name.
I can get the file name in UDF which I have already created but i am not usre if it working.
Can you please help?
Any help will be greatly appreciated.

Archana

The xml must be getting added in the below part of the code. It is coming from arg[0]
You can put a check and get it removed.
while ((len = arg0.read(buffer)) != -1) {

Dynamically changing the name of the .dll file to load in call Library
Our current model is to use dll files as "plug-in" modules for instruments and a top layer test step calls the appropriate driver dll.
For instance
the TestStep is called with the kenmore.dll passed as a parameter so the kenmore.dll file is loaded, the functions are registered and the functions are called. Next the TestStep is called with whirlpool.dll as a parameter now the whirlpool.dll is loaded the functions are registered and the functions are called. This works very well in our current CVI/LabWindows environment. Now we plan to work with LabView, we wish to retain this model (as DLL files, there are advantages in our model for us). We have not found a way to load these dll files from LabView without hard coding the path and filenames in.
Any suggestions on how to dynamically change the path in the Call Library module, or another suggested method of loading the dll via LabView?

As Ben has pointed out LabVIEW
scripting may be a possibility but you are going with that in highly
unsupported area. Also I happen to know that changing the library name
of a Call Library Node through scripting has produced unsupported
feature errors previous to LabVIEW 7.1 eventhough the method was there.
And LabVIEW 8 hides the whole scripting business behind the license
manager.
Another approach at least if the different DLLs do not change to often
thier functions and parameters would be to create a wrapper DLL. Have
it a method that loads the desired DLL and links its functions to
internal function pointers. Then when calling the actual function entry
points just redirect directly to the correct fucntion through that
function pointer. Since you are already working in CVI creating such a
DLL should be only a matter of taking out a little bit of your already
existing code and put it into a DLL project.

Reading Dynamic Files using File port
Hello All,
We have a requirement in our project where we have to use File Port to pick a set of IDOC Flat files from a given directory. The File Port only allows us to pick a file with a specific given name and does not allow us to pull file with a pattern for .eg. We can pull a file abcd.txt but cannot pull something like abc.txt. Our requirement is to pull abc.txt using the File Port.
If anyone has any idea about this, or any past experience with File Port in this regard, then please respond at the earliest.
We have created the file port with follwoing parameters:
Unchecked the Unicode Format System Setting
For the Inbound File:
Function Module: EDI_PATH_CREATE_CLIENT_DOCNUM
Directory is: A valid directory path
File Name: abcd.txt
Thanks in advance.
AbinashIf the xml files are all in the same directory (not in any directory structure relative to the parent directory), you can do something like this.
- create a bpel process to read the zip files as it comes into the directory]
- Have a file adapter inbound for the receive
- Call windows .bat command within the bpel process to run an unzip command on that directory
- Have another bpel process that reads *.xml files and this will get kicked off.
There are so many ways of solving this: like having a cron job to unzip the files coming in etc. But, if you have a directory structure for these XML files and if the structure is dynamic, it is difficult to configure the file adapter for that. -

Lion administrator setting changed to read only for file sharing. Now hung machine
I was trying to network my Mac with a WIndows 7 machine and tried to have my name in the file sharing read write instead of other users such as administrator when I changed the administrator to read only for file sharing rights and could not add my name as a file sharing user with read write permissions Really silly move
I have performed a repair of disk permissions however still hung.
Whats worse is that my time machine for the last three days has been disconnecting when backing up leaving a partially complete backup. Backup failed. I also left a apple support community message a few days ago to solve it.
So its critical
Timely HELP is needed.This same problem happened to me, all the sudden one day my mac decided to revert to the original standard root username and password which I obviously did not know. In order to change this:
1) Activate single user mode on reboot as by pressing cmd + s as your computer starts up. Make sure you do it right away, and keep the keys pressed down.
2) Where the cursor pops up, type exactly
+/sbin/mount - uw/+
3) When the next cursor pops up type exactly
passwd
4) Then you can type any password you want (now changing the root password to be what you want)
Note you will not be able to see what you type, but the text is being recognized
5)The computer asks for you to retype the password, retype it
6) Type reboot
Once the computer restarts you can navigate to system preferences>accounts> and then unlock the account (lock is located on the bottom left corner) using Username: root and the password you just set. Henceforth, you can appoint your account as the administrator. Hope it works!
