Read group of files
hi. i've got an issue. my code is prepared for one file reading:
FileReader fr = new FileReader(file_name);
BufferedReader br = new BufferedReader(fr);
FileWriter fw = new FileWriter("out.txt");
now i have to read a hole directory in a loop for example and write it to one out.txt. how can i do it, what should i put into:
FileReader(?)?. thanks for any advice, best regards!
now i have to read a hole directory in a loop for
example and write it to one out.txt. how can i do it,FireWriters have an append flag for their c'tors, if that's what you want to know. For more information, consider reading the API docs. if you don't know how to use a loop, Google for "Java tutorial".
what should i put into:
FileReader(?)?. thanks for any advice, best regards!A reference to a File instance. Best, one obtained from theDirFile.listFiles().

On list view in folders, how do I click drag second group of files?
Back in Snow Leopard and all previous systems, I was able to on list view in a folder be able to click and drag a set of files to select them, then by pressing command again, click drag on a second group of files I would like to select together and so forth. This was handy as I can select really quick on list view folders and files which I need. Obviously the files are listed alphabetically and I don't need to select them all, only groups of files eg. files which are all pdfs that are randomly spread out based on names, or mp3s which I want to move but not move the folders that are in the same folder. You get my drift.
Now on Lion, I can only click drag first group of files, and then on second selection by pressing command, I cannot drag anymore files except for the first click of the file I select.
Is this going to be like this for Lion or did Apple leave this out accidently? Is there a setting I can set back to previous style of group click/drag selection?
This is a bit annoying as I would like to quickly group select a could of groups in a folder QUICKLY to drag to other folders or to simply trash them all in one go. Now I have to stop and start and it slows down my productivity when I have to clean my files on my computer.
Thanks for your help.I have the same problem.
I've made another post...

I didn't do a complete inspection of your code (because it's too much and unreadable as it is) and I don't know POI, but creating a new HSSFWorkbook for each input file sounds fishy to me ... try re-using the workbook and just creating a new sheet in each iteration. -
Disable Save or Save As for Read Only mpp file
Hi,
I have a read only mpp file and need to make sure that it cannot be Saved / Saved As by anybody in Team. They should only have access to view the file.
How can enable a file which does not allow save / save as?ihvarrived,
You didn't mention anything about being in a Project Server environment, so I assume Shiva's response has no meaning for you.
With regard to an approach to prevent unauthorized users from saving a file let me again stress that, in my opinion, the best approach for this issue is training. That has the great advantage of mutual respect and cooperative effort in a team environment.
To implement a more covert approach you will need to do the following:
1. With the file open go to Developer/Code group/Visual Basic
2. Hit the Project Explorer icon
3. In the Explorer hierarchy, under the VBAProject double click on the "ThisProject"
4. In the code window, paste the following code:
Private Sub project_open(ByVal pj As MSProject.Project)
MsgBox "This file is write protected. You can make changes" & vbCr & _
"for temporary what-if scenarios, but you will not be" & vbCr & _
"able to save without the correct password", vbExclamation, "Warning!"
End Sub
Private Sub project_beforesave(ByVal pj As MSProject.Project)
pass = InputBox("enter save password")
If pass <> "xyz" Then 'string in quotes is the password you chose for saving, "xyz" is for illustration only
SelectAll
EditDelete
End If
End Sub
5. While still in the code window, go to Tools/VBA Project Properties/Protection tab
6. Check the "Lock this project" option
7. Enter and confirm a password. It can be the same as your save password or a different password (This will insure that only you can view and modify the above code)
8. Hit OK, then File/Save [your filename] to capture your macro in the file. Note, at this point you will be required to enter your save password.
Be advised that if a user does attempt to save without the correct save password, the file will be zeroed out and saved (i.e. nothing). That means that whenever you save the file you should also save a backup under a different name, so you can restore the
file if necessary. I couldn't figure out a good way to work around this problem. If the user always tries a "Save As" this wouldn't be an issue, but if they chose "Save" and you don't have a backup, you're screwed.
If this answers your question or is at least helpful, please mark it accordingly.

How to read Group ID from Value Mapping Context in Cache Monitoring ?
Hi friends,
In RWB --> Cache Monitoring --> Integration Server (Java) -> (Search for Value Mapping Groups) in this each item is identified by Value Mapping Group (GroupID, Context, Identifier/Agency, Identifier/Scheme). Either we create Value Mapping Table in ID or replicate value mapping data directly from text file/SAP table etc., in run time cache, data will be identified in this manner.
Now, our requirement is to delete a record the Cache for a particular context. Two operations provided by XI one is 'Delete' and another one is 'DeleteGroup'. When we use either of this, we should know GroupID. Suppose, I replicated some large amount of data from my text file in Runtime Cache. Value Mapping Table is like that IN --> India, US --> USA, AU --> Australia, EG --> Egypt. Now, I am required to write a program to get the input country code from user which is going to delete in the value mapping table like IN/AU.... For this, what logic we should follow in the program is, First we scan the value mapping table and find the record (country code) which is match with the input. Then find the GUID value for this record. Now we use the DeleteGroup Operation and pass this GUID and then delete the record.
So, in essence, how to read the GUID from value mapping context.
Friends, Kindly help me to do this.
Thanks in advance.

Reading a csv file and bind to a data grid
hi. doing a school project and been searching. the application reads a csv file from c:\stocklist.csv, and then this in a button called btnLoadData, and now need to read in a data control called DmgDisplayData. do i put the code in the button, or in the
data grid. been searching, but cannot seem to find any thing. so, where do i put the code, in the data control, and does any one have an example code how to read into the data fields. also need to have one field, able to edit, the other three or four fields,
read only. can any one help me out. never covered this in the subject, but did do file streams a few years ago in vb, but usin g c#,a dn the help in visual studio, not that helpful, with a blind person using a screen reader, jaws for windows from http://www.freedomscientific.com,
and using visual studio 2013 community edition. can any one help me out, been searching and trawling about 15 to 20 pages so far, and did try a couple of sites, but could not find, any help. thanks. the application is to read a csv file from a button, and
load into a data grid, then have a message box, saying file load successful, then have one field, order on as edit, but the other fields, read only, so do i need the navigator buttons, for next, back, previous, etc, and how do i code that as well. not to do
it for me, want to learn, but maybe some sample code, did do navgiator controls, years ago for a vb project, but need the c # example for that, thanks. then you have a button, Save data, that saves the csv file in the data grid. so can google for that. then
have a toolbar, with a button saying, Sort Items, a tool strip, and when you click on that button, you have a drop down list, of three items, then a sort button, which will then sort the array in the data grid. so, do i need another form, or just do the combo
box as an invisible control, then just refrence, that in the toolbar. so need to use th file class and an array, learnt about single and multi arrays. any ideas. thanks.
http://startrekcafe.stevesdomain.net http://groups.yahoo.com/groups/JawsOzHi Marvin,
-->where do i put this, in the data grid click event. or in the form load event. thanks.
You could use this code after you initialize the DataGridView. you could put it in the form load event.
-->what about how get the tool bar and the combo box and another button, then sort from the combo box on the array for the collumns, for to set focus to the first read collumn for the data grid. how do i do that, close the parent form, and have another
form on the toolbar.
Since this is another issue of this thread, I would recommend you posting it with
another thread. We will focus on that thread to help you. Thanks for your
understanding.
BTW, Before you asking questions, I suggest you could learn to make it by yourself. You could begin to learn winforms in MSDN articles:
https://msdn.microsoft.com/en-us/library/dd30h2yb%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396. Or Google it, you will get many answers. In that way, you will learn more from the questions.

Grouping of files in the file system
hi all,
i am using Forms [32 Bit] Version 6.0.8.24.1 (Production).
with the help of host command i am uploading any type of files from user specified location to specified directory.
My requirement is like the files should be grouped wile saving to the specified directory. But how the grouping can be done?
Please advice me on the grouping. on what basis grouping of files can be done and how we can access them?
Please advise.
Thanks..hi Christian,
and basing on what condidtion should files be "grouped"? Care to add an example on what this "grouping" is supposed to do?right now i am storing all the files in specified directory.
For example if i am having 500 files with different file types. How user can be identified which file for what. To over come this problem grouping should be done.(purpose)
So in the form i should provide provision to create the group.
Please give me ideas how grouping can be done on the files?(the grouping can be of any logic).
note: user cannot the create directories of his own. otherwise we can store files in these specified directories.
Please help.
thanks.. -
W7 client machine stuck on startup "Group Policy Files Policy"
we have some w7 machine getting stuck on boot up before ctrl-alt-del, once verbose message was turned on for troubleshooting, we noticed they were stuck at "applying group policy files policy".
we had let it wait for more than 60 minutes at time and it would still be stuck. (thou mouse / kb still responsive)
this problem however, is not re-produceable on demand, if we power off the machine, it boots back up with no issues.
checking the group policy log, we didn't find anything weird, but was not sure if that's the right place to look thou.
we do have two group policy preferences pushing out host files as well as desktop shortcuts, might that be the culprit?
thanks!> we do have two group policy preferences pushing out host files as well
> as desktop shortcuts, might that be the culprit?
My recommendation: Use Group Policy Preferences as you like, but do NOT
use the "Files" extension.
Why? GP Processing at Boot/Logon is a synchronous foreground process
that cannot be interrupted (as you are already experiencing ;-)).
Replace GPP Files with a script that runs some robocopy commands. Start
this script through a scheduled task at boot or logon, so that it can
run asynchronously in the background, not disturbing the user experience.

Problem reading custom property file from custom event handler.
Hi,
My custom event handler needs some bits of information that I have set up in a property file. However, when the event handler runs it throws a FileNotFound exception - actually its because permission was denied.
I have added the code System.getProperty("user.name") to find out the actual user that the event handler is running as. It reports that "oracle" is the user.
That's great. However, the permissions on the file will allow oracle to read/write the file. If I log onto the server where OCDB runs (as oracle), I can vi the file.
The file is owned by another user, but the "oracle" is a member of the group that has read/write (we're running on a unix box). The file is not 777.
The event handler is actually calling a static utility method that returns the Properties. This utility is used elsewhere in other custom apps in conjunction with OCDB (on the same server). It works there, so the utility is functioning correctly.
Is there something going on that I'm missing? Like somehow the event handler is acually runn as somebody else?
Here is the node log.
2007/07/17 12:52:16 [oracle.ifs] [37] 434364 system FINE: Error /opt/csc/sfi/configuration/sfi.properties (Permission

Thanks in advance for the help.
WinstonMatt,
Sorry to have wasted your time. It was a server reboot issue. The ocdb server hasn't been restarted since early July. We added the users and groups late last week. Although we tested on line, the server wasn't quite up to speed with the new changes.
We bounced the server and all is well.
Thanks

Group the files based on their extensions
Hi,
I am traversing a dir and listing all the files under that directory. Now i want to group the files based on the extension and just print the number of files with each extension.
ex:
Extension No.of Files Size of the files
.java 10 23455 bytes
.html 2 1000 bytes
I am able to get the extension of the files. I would like to know how to proceed after that.
Any sample code will be helpful.
Regards
KuttyI have used a method to list all the files in the directory. After adding files with same extension to the HashMap. i am printing files after reading file by file. I need to print the files once i complete reading all the files in the directory.
Any suggestions?
private void listingFiles(File f )
Map extensionMap = null;
File[] files = f.listFiles();
for( int i = 0; i < files.length; i++ )
File file1 = files;
Dprop.size += files[i].length();
if (file1.isFile())
fcount = fcount +1;
if (extensionMap == null)
extensionMap = new HashMap();
// Group files by extension
for(int idx = 0; idx < files.length; idx++)
if (files[idx].isFile() && files[idx] != null)
String ext = getExtension(files[idx]); // get the extension
ext = ext.toLowerCase();
List fileList = (List)extensionMap.get(ext);
if(fileList == null)
fileList = new ArrayList();
extensionMap.put(ext, fileList);
fileList.add(files[idx]);
// Access all the files by extension
for(Iterator extensionIterator = extensionMap.keySet().iterator(); extensionIterator.hasNext(); )
String ext = (String)extensionIterator.next();
List fileList = (List)extensionMap.get(ext);
System.out.println("\n\nNo of Files "+fileList.size()+" with extension '"+ext+"' in '"+f+ "' Directory");
for(Iterator fileIterator = fileList.iterator(); fileIterator.hasNext(); )
File file = (File)fileIterator.next();
System.out.println("File Name "+file+" File Size "+file.length());
else
dcount = dcount +1;
listingFiles( file1 );

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:

Selecting a group of files and putting them in a newly created folder?
If I select a group of files in finder or on my desktop -- is there a command to create a new folder and put them in it? (I'm thinking of how you can take a selection in iTUNES and create a playlist from the selection).
(I know how to create a folder and then drag my selection into it).
Thanks!Open the Script Editor in the /Applications/AppleScript/ folder and paste in the following:
tell application "Finder"
make new folder at desktop
move (selection as alias list) to the result
end tell
This script expects that two or more items are selected. You can enable the script menu in the AppleScript Utility and then add the script to the menu for easy access.

Why one group of files takes so long to copy
Hi... I have two different folders full of files that I occasionally backup to another location. Both sets contain approximately 3000 files each. However, what I will call set 1's 3000 files represent about 700 MBytes of data while the 3000 files in set 2 are about half that size at about 350 MBytes.
The vast majority of those files are never changed. Instead, each week perhaps a few kilobytes and maybe 10-20 files might change. When I copy set 2 to its backup location, the copy might take 15 seconds tops. When I copy set 1 to its backup location on the same drive as set 2, the backup takes at least a factor of 10 longer... Maybe more... I could imagine a factor of 2 since there are twice as many MBytes of data in that set 1 but why might it be taking so, so much longer??? I've looked at the file attributes between the two sets and they appear to all be the same.
Even more interesting, if I do the backup for set 2 (the faster one) that I said maybe takes 15 seconds tops, if I immediately do the same thing again, it now takes less than a second meaning that the system seems to know those files have not changed since the previous copy. However, if I do the same with set 1, the second immediate copy takes every bit as long as the first copy just took moments before... It's as if something is telling the Finder to go ahead and recopy ALL of those files every time whether they have changed or not.
Any input on why I might be seeing that??? I care because I also backup these files via an online backup service and that set 1 group of files always takes a ton longer on that service as well. What might cause this???
thanks... bob..Well, maybe more detail would help but I was trying to keep it simple. There are certain files that I now and then copy into encrypted, sparse disk images and I then backup those encrypted disk images elsewhere. Currently I open the disk images which then shows the files/folders but those might be a few weeks old. I then open the same folders that exist elsewhere on my computer and that's when I use the drag and drop to update what will soon be relocked up into the encrypted disk images.
Sets 1 and 2 as I described them above are just natural groupings of files/folders I once chose those these encrypted disk images wouldn't be incredibly large.
I do have Disk Warrior as somone asked above...
And I don't have Carbon Copy Cloner but I do have its cousin, SuperDuper which I used to backup the entire computer to a backup drive now and then.
And I doubt I'm running into memory problems as this is a new rMBP with 16 GBytes of RAM
I could use SuperDuper to copy these files for me... Might be worth a try... But it's just so curious that one group of files copies in an instant when you copy and then immediately copy again while the second group seems to want to redo the copy every time you request it... It might just be a few funny files in that one group... Interesting... -
Hi Experts,
How to download a READ ONLY excel file to workstation (local Machine).Hi kaleemullah,
Steps to create a BDC program.
1. Create an internal table with fields same as Excel sheet fields.
2. Declare an internal table with BDCDATA table to store the BDC recording.
3. Declare an internal table with BDCMSGCOL to store the error messages after
the execution of the BDC.
4. Write the code using the fun. module ALSM_EXCEL_TO_INTERNAL_TABLE
to upload the data from the excel sheet.
5. loop that internal table and write the Subroutines to fill the internal table
BDCDATA with the recording of a specified Transaction Code.
6. Using Call Transaction execute the BDC recording.
7. Check Sy-subrc = 0 and store the error messages in the internal table.
8. If you want you can pass those error records to a session using the SESSION method.
Here is an example of a BDC program, but this program is from a text file. Change the function module WS_UPLOAD with ALSM_EXCEL_TO_INTERNAL_TABLE
to upload an excel and write the program with your BDC recording. You can do recording using t-code SHDB.
Sample Program:
REPORT ZRAJ_DATASET_XD01 NO STANDARD PAGE HEADING LINE-SIZE 132
