Can I save to memory sticks for read and write access?

I use M.S. Office for Mac to do my admin. I would be very grateful if anyone can help with my queries.
I want to save work to media that allows me read and write access. Saving to discs (of any type) does not allow any editing.
1. If I save to a memory stick will I be able to save and update my work when I want to?
Also;
2. Would a memory stick have to be formatted with to be suitable for Mac?
3.If the memory stick can be used for the purpose, I want to encrypt it; how would I do this please?
4. Would encrypting place a limit on the capacity of the memory stick that can be used, e.g. I have a choice, including 8Gb and 16Gb.
5. I have heard that passwords can be created by Mac; what is the method for doing this please?
Many thanks for in advance.

There is terminology here I am unfamiliar with. I feel I have embarked upon a complex path.
I do not know what HFS+ is.
HFS+ is the Mac OS X file system. Hierarchical File System Plus (Plus as it used to be HFS, but then they improved it and said +)
By default a USB flash drive generally comes formatted with FAT (from the Microsoft MS-DOS days, but is a universal format - it might come with FAT32 or exFAT as well - still from Microsoft). Mac OS X can read/write these, HOWEVER, its FileVault whole disk encryption is only designed to work with HFS+, which is why I mentioned it.
Applications -> Utilities -> Disk Utility can be used to reformat a disk, USB Flash drive, etc... NOTE: reformatting does erase everything on a disk, so keep that in mind.
What is the difference between File Vault and .dmg in disk utilities?
FileVault is whole disk encryption. Everything on the disk is encrypted. and you need to enter the password just to mount the device.
A .dmg file is a regular file that happens to contain a file system inside of it. When you double click on the .dmg file, Mac OS X will mount the file system inside as if it was a disk. If the .dmg file is encrypted, then you will be prompted for the password before Mac OS X will mount it. A .dmg is just a container for a file system. Inside that contain is a full file system with files and directories just like any other file system.
You can create read only .dmg files, you can create read/write, you can create sparse (you declare the maximum side, but the initial size of the .dmg is small and will grow to the maximum size as you add things to the .dmg, you can create encrypted .dmg.
Since a .dmg is just a file with no special attributes on the outside, it can be copied around. You can copy it over the network, you can store it in the cloud, you can put it on a USB Flash drive, you can put it on an external disk, etc...
If the device you put it can be mounted by Mac OS X, then you can double-click on the .dmg and it will mount the file system inside the .dmg and you will be able to access the files in the .dmg
This even includes USB Flash drives that use the FAT format family. But you existing external disks can be used for that as well.
If I used an external hard drive for the purpose I have in mind, would the disk .dmg utility allow me to access folders and files for editing or should I approach the task in a different way? I would still wish to encrypt.
As I said above, the .dmg is a full file system where you can store files and folders inside a .dmg container file. And you can encrypt the .dmg so it is secure.

Instrument i/o assistant always generates async methods for read and write!

I am trying to generate VI by instrument i/o assistant, but it generated 'Visa write' and 'Visa read' always in asynchronous mode. Even if I unchecked asynch boxes in MAX->Visa Test Panel.
I need only synchronous mode! And it is very uncovenient after open front panel change Synchronous I/O Mode from Asynchronous to Synchronous!

after generate does not work.
Is it possible you don't have a sufficient amount of wait time between a VISA Write and VISA read to give the instrument time to receive the communication and turn around a response? Take a look at Basic Serial Read and Write example VI. If you are using the I/O assistant and checking things manually, it will work because there is no way you can generate a Read too fast. It still would take a fraction of second to generate the write and do whatever clicking to generate the read.

Open file for reading and allow access by others

How can I open a file for reading and still allow others to access (read and write) the file? I plan to keep this file open for the duration of my program and close it at the end. However while my program is running another program will need access to the file so it can write to it. I may be wrong, but I dont think that setting the appropriate permission will solve the problem... Thank you for your time.

hi jmcbee,
I think as long as "readers" open a file as "ReadOnly", then the OS (at least Windows) will allow another process to open and write to the same file without a problem. It's been a while since I've done this - maybe 7 years - and I may have opened the "writer" first, though doubt it makes a difference.
Have you tried?
Cheers!

Read and write access for shared folders shouldn't be enabled but it is.

I have an external hard drive with all my media stored on it. This is shared over the local network so that others on my network can access it.
However I set it u for read only access (I dont want the rest of my family to be able to delete files) but it persists to have read & write privaleges.
Im sure im missing a really obvious point but I can't work it out. So was hoping someone could help.
In System Pref-Sharing-File Sharing the folder is shared with 3 users added:
Alastair Riddle (Read and Write) <----My account
Staff (Read Only)
Everyone (Read Only)
I have applied permission to all folders, but guests appear to be able to log on and have full read write privaleges.
Your help would be appreciated,
Ali

I'm no expert on this one, but for the others to be included under the Staff heading, I believe they have to be added to that group.
It may be easier to add them by name and set to read-only, and add an entry for Guest as read-only.
And ensure that the external drive has Owners Enabled.

What Floppy Drive can I use with Mountain Lion to read and write floppy which can be read by SE30 with 7.1

I want to File Exchange between an iMac with 10.8.4 and a SE30 with 7.1.
All I want to do is install some software, such as Word 5.1 and a Chess game and some Fonts.
I have an external USB Floppy Drive but my iMac can only write to it IF I format as FAT, if I format it with the SE30 it can only be read and not written onto by the iMac.
Is there a way I can actually format/read/write Macintosh extended (HFS+) with Mountain Lion?
The external USB Floppy is a generic black one I bought from Amazon last week.
Someone else said I should get a Macally USB Floppy Drive and that reads/writes HFS+ etc with 10.8 no problem.
Is this because the Macally was released along with the Bondi Blue iMac?
I have tried using Apple Exchange on my SE30 - recorded some files onto the FAT formatted Floppy, and read it using Apple Exchange, but when 'translating' the Files transferred over as generic files which were no longer Macintosh programs or Files (eg Word 5.1 application or extensions/ Font suitcases etc) and could not be read.
Is there a way round this?
Or is there any way I can mount/read/write from the generic USB Floppy DRIVE with Sheepshaver (with 7.5.3)?
Any help or advice would be most appreciated.

>surely there must be some Terminal command or workaround for 10.8 to be able to Format in HFS?
Using dd to write an existing HFS disk image to a floppy may still work (but formatting/writing HFS from the operating system does not). You may want to compare this with the technique described in the article below. Obviously, this is only of interest if one wants to try creating floppies from certain (Disk Copy 4.2-style) downloaded 1.44 MB disk images.
http://lowendmac.com/brierley/08pb/classic-mac-boot-floppy.html
>If I got hold of an old iBook or Powerbook G4 (my sister has one) could I plug the USB Floppy drive I have into one of these and copy files over this way?
At least according to the following Wikipedia article, writing HFS has not been supported since Mac OS X 10.6. This should mean that your idea with the USB floppy drive connected to one of the older computers mentioned could work. BTW, I do not think that the USB floppy drive type/make/model is of importance in this very context.
Another idea could possibly be to use an even older intermediate computer for other file transfer methods (without a floppy).
A PowerBook 520/520c/540/540c could run Mac OS 8.1, if at all necessary. It has built-in Ethernet (an external AAUI to RJ-45 transceiver is used), which would allow TCP/IP connections over a network. A LocalTalk connection to the SE/30 can be established via a plain Macintosh MiniDIN-8M to MiniDIN-8M printer cable. With the correct SCSI cable/adapter, one could also use the PowerBook as an external hard disk for the SE/30 in SCSI disk mode.
A PowerBook 5300 can run Mac OS 8.1 or higher, if necessary. It does not have built-in Ethernet, but a PC Card (PCMCIA) network card can be used. Furthermore, with an inexpensive PC Card adapter for CompactFlash and a CompactFlash memory card, the computer would have a simple removable "hard disk". The CF card (in Mac or PC format) can be read by a modern computer (a USB reader may be needed), making it ideal for file transfers. LocalTalk can be used here too, and so can SCSI disk mode (HD target mode).

Script Component - variables locked for read and write not available outside of post execute

Hello,
I have two Data flow task,
Frist one has OLE DB Source and Script Component as Transformation
I have package level variable called AllSiteIds
In first DFT, i have a local varibale that is declared before PreExecute method and after ScriptMain:UserComponent line.
This local variable is used in Input process method to concatenate the one of the row values like below
SiteId = SiteId + Row.SID.ToString()+",";
The package level variable AllSiteIds is set for ReadWrite on script component.
In my post execute i am setting package level variable AllSiteIds
Variables.AllSiteIds = SiteId;
In my second DFT, i have OLEDB source and Script transformation and i am accessing the package level variable AllSiteIds in Preexcute but not able to do so and getting error mentioned in subject.
My goal is to create string of all SiteIds delimited by comma and have it available in second DFT to be used in Preexcute.
The sql command i am using to get all unique siteid's is
Select SiteId from dbo.Services
Group By SiteId
Order By SiteId
Using the result from above i need to create comma delimited string of all site ids' and store it in variable so i can use it in pre excute of second DFT.
Please suggest on how to accomplish above?

If all you want is to generate a string of ids then you can simply use a Execute sql task for this and use a query based on FOR XML PATH which will generate the string of ids
http://visakhm.blogspot.in/2014/01/rowset-concatenation-with-special.html
then inside execute sql task set resultset option as single row and store the result ina SSIS varaiable of type string.
Once this is done you can then use this variable inside the subsequent data flow task

Read and write a .CSV file contains cirillic characters issue

Hi guys,
I am a developer of a web application project which uses Oracle Fusion Middleware technologies. We use JDeveloper 11.1.1.4.0 as development IDE.
I have a requirement to get a .csv file from WLS to application running machine. I used a downloadActinLinsener in front end .jspx in order to do that.
I use OpenCSV library to read and write .csv files.
Here is my code for read and write the .csv file,
public void dwdFile(FacesContext facesContext, OutputStream out) {
System.out.println("started");
String [] nextLine;
try {
FileInputStream fstream1 = new FileInputStream("Downloads/filetoberead.CSV");
DataInputStream in = new DataInputStream(fstream1);
BufferedReader br = new BufferedReader(new InputStreamReader(in,"UTF-8"));
CSVReader reader = new CSVReader(br,'\n');
//CSVReader reader = new CSVReader(new FileReader("Downloads/ACTIVITY_LOG_22-JAN-13.csv"),'\n');
List<String> list=new ArrayList();
while ((nextLine = reader.readNext()) != null) {
if(nextLine !=null){
for(String s:nextLine){
list.add(s);
System.out.println("list size ; "+list.size());
OutputStreamWriter w = new OutputStreamWriter(out, "UTF-8");
CSVWriter writer = new CSVWriter(w, ',','\u0000');
for(int i=0;i<list.size();i++){
System.out.println("list items"+list.get(i));
String[] entries = list.get(i).split(",");
writer.writeNext(entries);
//System.out.println("list items : "+list.get(i));
writer.close();
} catch (IOException e) {
e.printStackTrace();
say the filetoberead.CSV contains following data,
0,22012013,E,E,ASG,,O-0000,O,0000,100
1,111211,LI,0,TABO,B,M002500003593,,,К /БЭ60072715/,КАРТЕНБАЙ
2,07,Balance Free,3

2,07,Balance Free,161
It reads and writes the numbers and english characters correct. All cirillic characters it prints "?" as follows,
0,22012013,E,E,ASG,,O-0000,O,0000,100
1,111211,LI,0,TABO,B,M002500003593,,,? /??60072715/,?????????
2,07,Balance Free,3
1,383708,LI,0,BDSC,B,??63041374,,,? /??63041374/,???????????
2,07,Balance Free,161
can somone please help me to resolve this problem?
Regards !
Sameera

Are you sure that the input file (e.g. "Downloads/filetoberead.CSV") is in UTF-8 character set? You can also check it using some text editor having a view in hex mode. If each Cyrillic character in your input file occupies a single byte (instead of two), then the file is not in UTF-8. Most probably it is in Cyrillic for Windows (CP1251).
If this is the case, you should modify the line
BufferedReader br = new BufferedReader(new InputStreamReader(in,"UTF-8"));toBufferedReader br = new BufferedReader(new InputStreamReader(in,"windows-1251"));Dimitar

Read and write with usb printer

hello friends
i m new in labview . can any body advised me how to read and write with printer that have USB interface . because latest printer connection are usb based not parallel port based.
any example or material.
i shall be very grateful to u
thanks

Hi,
It depends on what type of driver you are using, and how that driver communicates with you printer.
There are lost of different ways LabVIEW can interface with external hardware, either using all libary function node, ActiveX, .NET, etc. It all depends on what type of driver you are using.

How do I use memory stick for pictures

How do I use a memory stick for my pictures? I put it in the side of computer? I want to look at
my pictures on it and save more on it?

Open Finder, the stick will be in the left hand pane, click on it and what is on the stick will show up in the right hand pane. Double click on one of them and it should open in Preview or iPhoto.
You can use iPhoto for this also and you can copy images from iPhoto onto the stick.
I dont use iPhoto, I use Lightroom, and when I do something like this I use Finder.

I want to copy images to a memory stick for sharing with my family. This was possible in iPhoto via copy/paste but does NOT seem to be possible with photos...

You can drag and drop (this will result in a compressed JPG) or hold the alt key and drag and drop (this will copy the original). You can also select the pictures and choose Export from the File menu.

I can't send a gift sticker for friend

I've purchased sticker in app line but am can't send a gift sticker for friend.
This is Order ID: MHVSWHHQ02 and receipt No.136044725959 for me.
Thank you.

I didn't realize what's this question was really about until days before.
There were news about apple calling off the Line's in-app function of sending gift sticker to friends, in the reports they only mention "for some reasons the Apple forced Line" to do so, and never explain, probably people would just like to have an answer from Apple.
I didn't even notice when they removed that function.

Online support says my imac (20" early '08) can only house 2 memory sticks of 2GB ea). Then, Apple tech on phone said I can actually install 2 sticks with 4GB each. If so, please tell me the EXACT specs on a 4GB stick I need (so many numbers and letters!

On apple site, it says my version of iMac (20", early 2008) can only house 2 memory sticks of 2 GB each.
But then called Apple, and tech rep told me i could actually install 2 memory sticks of 4 GB each - for 8GB total.
there are so many abbreviations, letters and numbers it's mind boggling.
So if i'm able to install this size, could someone please tell me what are the EXACT specs of a 4GB memory stick I'm needing?

Crucial have an application to run on you Mac and that will recommend memory that will work.

You can also try OWC for memory as well.
