How to check wwheter two files are the same?

Hi,
I need to check wheter two files are the same. Their names and paths may be different. How to do that? Do u have any links / examples?
Important notice: Files used in the application will be big (ie 1, 2gb)

Comparing a hash, if you have to calculate it each
time, is bound to be slower than a byte by byte, or
character by character compare.
This kind of comparison is used mostly in things like
content management systems, when a new file of data
is checked to see if it's identical to a file already
entered, hash values being stored for each file
already in the system.
And comparing the hashes can only prove the files are
different, if the hashes are equal that doesn't
absolutely guarantee that the files are the same.
Normally you'd confirm a matching hash by actually
comparing file content.Depends on how good your hash is..but in general...yes. I was only saying that it's faster if you're always maintaining a has of the file.

Photoshop CS4- Does anyone know how to tell if two people are using same file?

Hi,
Thanks for your response. I'm not the solution in the link.
The problem that I am having at work it that several people in our department want to be able to update a file, but we want to be sure that no one else is currently editing that file. If someone has the file open, it's helpful to know the user's name so we can talk about when the next person can edit the file. This works in Excel files that we use, and I would love to find out how to do it in Photoshop and Illustrator.
Thanks for the help!

How can i add two values under the same property?

Hi all,
How can i add two values under the same property name in a
prop list? For example:
[question1: "item1","item2", question2: "item3","item4"]
To be more precise, i am creating a property list and I want
whenever a two values have the same property name to be added int
he list under the same property. For example:
gMyList.AddProp (#""&question&"" & x,
member("input").text)
question is a variable that is updated fromt he user's input.
Now, whenever somethign like this happens:
question = "question1"
member("input").text = "five"
question = "question1"
member("input").text = "six"
I want to output list to be:
[question1: "five","six"] and so on
Any ideas?

Maybe you could make each property a list (so you have a
property list full
of lists), and add multiple values to the list held in a
particular
property?

How do I separate two movies on the same timeline?

I'm using Premiere Elements 11 but have not used it for a while so I've forgotten much of what I've learned. So here is my question: I have two movies on the same timeline. How do I separate them. In other words, how can I move one over on the timeline so it will not confuse my editing of the other one? But better yet - how can I just take one movie off the time line completely and edit it later as a separate movie. I really have four short movies - one minute long. I'd like to edit them separately, with a new file name. I don't know how to do this anymore.

I have been doing some homework on the questions that you raised in this thread.
Observations....
1.
After you import a video into Project Assets, you can right click it, select Rename. That file when dragged to the Timeline will have the new name.
But...
If you import a video into Project Assets, drag it to the Timeline, right click the Timeline clip, select Rename from the pop up, then the Timeline file will be renamed but not its thumbnail in Project Assets. You would have rename that Project Asset thumbnail to match if you wanted to. But, these renamed files still trace back to the original with its original file name at its hard drive save location.
2.
About getting off your Timeline...one way would be to export the clip selectively if it were in group of clips on the Timeline. Two requirements for that
a. In Edit area, set the gray tabs of the Work Area Bar to span just the segment to be exported
and
b. In the export area, have a check mark next to "Share Work Area Bar Only" option.
3.
If you brought a clip into Project Assets, double clicked it to open its Preview Window, you could trim the clip with the Set In and Set Out points and create "subclips" with new names in Project Assets. These "subclips" would be part of that project's media that could be dragged to the Timeline when needed.
Please review and determine if any of the above is going in the right direction for what you want to do.
Thank you.

How can I have two fields with the same name if it makes sense?

Hello, folks :)
I have a pretty hard time figuring out how I can have two text fields with the same binding name.
The whole problem is that when I need two fields with the same binding name they are still differnent coz they have the same name but differnt indices.
I should make a form filled at runtime by merging a pdf form file and an fdf file data file. And I have no choice to do it differently. And my form file needs some data like customerName, companyName twice in one form. But there's only one possible buinding name indexed zero.
How can I create a field with absolutely the same name or is it just impossible due to possible name conflicts? And is there a workaround to this problem? I just need one piece of data repeated in different places.
Thanks for your replies :)
P.S. if u think that the problem is not clear enough let me know. I'll supply you with more details. But the general process can not be changed.
One pdf should be mergred with an fdf with as the result of their merge a new filled and flattened form. I have no control over fdfs their are generated by Oracle and I can not fill the form using XML files coz this process should be integrated in a working application.

I just thought about a really ugly workaround with a server-side script adding values to fdf files but it's a bit of work and tests and personally i think it's a bad idea :-(

How do you sync two Ipods to the same MacBook?

Have a nano already synced to my MacBook. Want to also sync my 5th gen 30GB Ipod to the same MacBook. Have only had my MB for 3 months after 18 years of PC platform (yes I'm drinking the KoolAid baby.) This notebook is fantastic.
An issue I had with my old PC was that you couldn't sync two Ipods to the same PC unless you held down the shift key while accessing ITunes to select a library - or something like that.
Please tell me that if I plug my 5th gen into this MacBook it won't overwrite my nano songs/info that are already on this MacBook? Apple has to have done it easier than how I had to do it with the PC. Any help from you experts out there will save me a ton of grief..........Thanks! R.Ty

Thanks!
No problem.
My issue is however that in addition to all of the songs that I have purchased via ITunes, I have about 600 songs from my own CD's on the 5th Gen that if I restore will be gone. Time - yes....money - a little.... It would be great if I could de-authorize the PC it was synced to and now work off my mac....
In that case, check out these different media recovery options by Zevoneer for copying music from your iPod to your computer.
http://discussions.apple.com/thread.jspa?threadID=1900086&tstart=0
And check out this older post of mine on different ways to copy music to your computer from your iPod as well.
http://discussions.apple.com/message.jspa?messageID=12000345#12000345
What you need to do is first copy all the music currently on your 5th generation iPod to your new Macbook. Once you have done that, you are free to *Erase and Sync* it upon plugging it in, or restoring it via iTunes as described above.
And if you are adding purchased music, you will need to authorize your computer if you haven't done so yet. To do this, choose Authorize from the Store drop down menu in iTunes.

How can i distinguish two controls with the same name?

I'm recording automated tests with VS 2012 Coded Ui Test for testing a web application.
In that web application it is possible to enter data in something looking like a list.
There is - per example - an Edit control sitting on a ColumnHeader with the name/text "Description".
Below that header is another Edit control for data input - containing the text "Description" too and which lies on a Cell control.
When i playback my recording, Coded UI Test looks for a control with the name "Description" and gets the one, it finds at first.
In that case the Edit on the ColumnHeader, which causes an exception, when the Text will be setted with the data input from the recording.
Unfortunately the controls have no ID.
Is there a way to distinguish controls with the same name?
Thanks in advance!

Hi Patrick Pirzer,
>>Is there a way to distinguish controls with the same name?
Based on the blog "How does “Coded UI test” finds a control ??", we know that to really find a control, it would be related to the unique properties as the search properties,
so if two controls have the same property, please use other unique property as the search property would be better.

How can I produce two outputs of the same project

Dear Sir,
My aim is to produce two outputs of the same master project,
HTML help and Webhelp each one will be used differently in my
compnay.
Producing two outputs is fine but the problem was that
external links are done differently for HTML help and Webhelp and
as I Knew from you that this can be solved using conditional tags.
Actually I am new to conditional tags and I don't know how to
use them. Could you please help me to do this or recommend a link
on how to use condtional tags to produce different outputs.
Thank you very very much

How to upload multiple .CSV files in the same time.

Hi Legends,
Can anyone please help me to resolve my issue?
This is very urgent and critical.

We need to upload the xx.csv file at the same time for these two users in oracle forms.

Thanks,

Madhusudhanan,
A couple of observations. First; always list your exact Forms version (eg; 10.1.2.0.2 not 10g R2). In most cases, the solution is different depending on the Forms version. Second; why must you use Forms to kick off a SQL Loader process? This is a server-side process and should be initiated by a server side process. If you absolutely must use Forms to kick off the process, again we need your Forms version in order to offer any solutions. Based on your code sample, I can asusme you are at least using Forms 9i becuase you are using WebUtil.
Is your Database and Application Server the same physical computer? If they are not, this would explain why your HOST command isn't working because HOST runs against the Application Server not the Database server.
Third; have you considered using and External Table (if your RDBMS version supports them) for each of the files you are attempting to upload? In this instance, it would be helpful to know your RDBMS version as well. External Tables can be a little frustrating to set up the first time, but as with any new construct you use - it gets easier the more you use it.
Fourth; are you getting any errors in your log file(s)? If so, what are the errors? Please list the full error message if you have one.
Finally, with respects to your statement:

How can I open two libraries at the same time on itunes?

Hey i need help on opening two libraries at the same time on itunes. I don't know if that is possible but need some advice if its possible. I already have several libaries but I need to compare labaries at times due to various users on my computer. Please help .

Not that I'm aware of. What exactly is that you want to achieve? There are tools for scanning media folders and adding any files not listed in the library, or deleting those that no longer exist. There are also ways to use one library for multiple users so that any tag update gets applied for everyone.

How can I unlock numerous files at the same time (i.e. photos) so I can make changes (rotate etc)?

Im using Lion on a MacBook Pro 15in (just under two years old) and I would like to know if I can lock numerous photo files at the same time so I can make changes to them. At the moment when I select an entire folder to go through and make changes, ie rotate in Preview, I am told with each photo that I have to unlock it. I am going through photos I took of archival material and have nearly 5000 photos to adjust and make changes to. This small step is taking up a lot of time.
I realise there will probably be a common 'sense' answer to this but it alludes me at the moment so any help would be appreciated.
Thanks

How do I put two galleries on the same page?

What's the "trick" to putting two galleries on the same page?
I've been experimenting, but it's not working out well. I have one working, but when I put the seond one on, all sorts of unexpected things happen. The first gallery goes up "over" the banner (it covers it??) and even though the sizes are spec'd the same, the second one shows up a lot larger as well.
It's very weird.
Any insight would be appreciated!
Thanks!
Michelle

Juan,
When Application Express finds a validation error, the page rendering step is executed again in the same database process used for the validations. So the procedure wwv_flow.accept, which is doing your validations, calls wwv_flow.show (a PL/SQL call) and passes information about the validation errors to the show procedure so that error text can be merged into the page rendering process.
If you want to simulate this you might need to save validation info in collections and build the "show" part of the page so that it knows how to run in "validation-display" mode, i.e., to be able to use the collections.

Is it possible to have two files with the same name on my Zen To

Hia,
Is it possible to have two mp3 files with the same name?; I.e if I'm ripping a Bach CD, there are several tracks that have the name preludium, and I hate to do the rename.
Also, will I be able to sync my Zen so that It will only recieve new files that have been added since I last connected my Zen to my computer?
regards,
Fredrik

I believe same filename is OK because the Zen Player does not really care about filename. As far as I know, the Zen database of the tracks in the player is based on the track information such as Title, Artist, Album and Genre. This means you cannot have two tracks of the same Title, Artist, Album and Genre in the Zen Player.
