How to detect the diskette is write protect?

I would like to write a file to a diskette. Before that I would like detect the diskette is write protect or not? and prompt a meaningful message. Could anyone help? Thanks!

Check the file API...there is a "canWrite()" method...I would assume this returns FALSE on a write protected disk. IF that does not work, then trying to write an actual file to a write protected disk would throw some kind of exception...which of course you can trap.

How to detect the path of Temp directory

I am writing a class library which allows users to manipulate a database in the web server java applications/applets. In my logic the Application/Applet communicate with a CGI script/Servlet in the server and that do all the database handling. My objective is to make the Client independant from the Database Drivers, and to some restrictions and possible security threats that can arrice when accessing the database directly.
99% of the work is done and now I am doing the fine tuning.
My Problem:
When the user downloading a blob object from the server database. each time the program read the blob it will get a new copy from the server. This is not good if the blob is large (few 100 megs) . So I am going to implement a cache system. but the problem is If I am caching in the memory it will not support large objects (Memory is a limited factor). So the preferance is use the Temperary files but I do not know how to detect the path to temperary folder.
And my 2nd questions is are the applets allowed to write and read in temperary folder.

The Java default temporary file path can be determined with
System.getProperty("java.io.tmpdir")This is typically the same value as the os environment variable

Your site was built using tables, whose sizes are defined in your site.
If we look at your first table definition, we can see:
<table width="861" height="1449" border="3" cellpadding="0" cellspacing="0" bordercolor="#868787">
Your table has a width of 861 pixels and an overall height of 1449 pixels. Anything you put into that overall box must fit those dimensions, else
it won't be visible. Anything you add above it will push everything down. You can redefine your sizing to let you edit more inside of the table elements.
This is why, when you type in more text, things act weird. If you are in Dreamweaver, you must find the right cell to put your text into and then enter
text there. Unfortunately, this is going to push things around, which were all lined up using tables. And this gets everything offset with respect to
everything else in your website.
And that is why everyone is saying, "Start Over!"
I just inherited a website that has been put together using tables. I'm going to have to expend considerable effort in rewriting the entire design of the
website because of that. because everything I intend to add to the pages on the site is going to need to be deconstructed in order to get it to work
properly if I'm adding text and pictures that need to line up with each other.
You need something done quick and dirty and the only way I can recommend you do that is to use Dreamweaver to show you the tables you have
and put what you need in a new table that is defined above or below the tables you all ready have defined. Do that and then get back to someone here
who knows how to make a website correctly to clean up your entire website and make it editable -- which will cost you some money, but it will be
money well-spent.
I like to quote this maxim: Good, Fast, Cheap. Pick any two. This works for website design. You can get it fast and cheap, but it won't be good. I
think you may have chosen that route.

How to detect the Acrobat Browser Plug-in version installed on a users system for non-IE browsers?

How to detect the *Acrobat Browser Plug-in version* installed on a users system, on Firefox, Safari, Opera, etc?
Or one script for detecting Plug-in version for major browsers. Need full example code.

Wrote an article on this with code samples (Javascript + HTML) - basically there are differences between IE and other browsers. Chrome natively comes with the Chrome PDF Viewer so I've incorporated that in my detection script.
The script detects the browser type, and the installed acrobat version...
Have a look here:

How to detect the HTML extension window close in In-design? Does the In-design throws any event on opening/closing of extensions?

How to detect the HTML extension window close in In-design? Does the In-design throws any event on opening/closing of extensions?
I have a HTML extension running in In-design CC 2014 version.
I want to perform some required set of actions before my extension window is closed(by clicking on the cross button on top right corner).
Does In-design throws any event for it? Or can we capture it using C++ plugin in some way?

Naah.......haven't got any event for that yet.
Although, since HTML extensions are using chromium browser, as a workaround, u can attach listener to HTML onClose event, but it won't solve any purpose if you
are looking to logout session or do some business login in your code.

How to detect the final loop iteration of a step in a PostStep Engine Callback?

I see the need to use a PostStep Engine Callback and look at the Step.Result container of the caller.
My issue: If the caller is configured to loop, the PostStep Engine CB executes with each iteration and I do not see how to detect the final iteration (which is the only iteration I am interested in).
Ideas are welcome. Thanks in advance,
Guenter

Guenter,
well, the way i discripted IS the generic way. The reason for this is the following:
You can compare TestStand very well with procedural programming languages. So you have variables with different lifetimes and scope. RunState is one variable, which is available in every scope, but it may have different content.
So you leaving the execution of your clientsequence in order to call the callback, you leave the scope of the RunState from your clientsequence. But only there the information is stored on how many iterations are left. It does not make sense to pass this anywhere, since the execution of your clientsequence has to decide if to loop further or not.
But, please note that there are different scopes for the "disable result recording" as well. You have found the most global one, the station option. But you can as well set this in the sequence settings (Edit >> Sequence Properties >> Disable Result Recording for All Steps) and at step-level (Run Options >> Record Result {uncheck it}).
Looping on a single step using the step settings, you can additionally choose not to record results for each iteration. This will lead to only a single entry in the ResultList, the overall result of the looped step (if resultcollection is enabled of course!).
hope this helps,
Norbert

Does any body knows how to detect the resolution of an inserted image in word?

Does any body knows how to detect the resolution of an inserted image in word?

I'm not sure I understand your reply but when you insert images into Word that are larger than will fit on the page, they are automatically compressed. If you right click and select Size and Position you can restore it to 100% but you will not see all the image.

Windows 7 Backup and Restore error code 0x80070013 The media is write protected

I have had a problem using Windows 7 64-bit Backup and Restore on two different brand new PCs. After setting up a backup to a WD MyBook 500GB external USB hard drive and performing the initial backup succesfully, when it tries to do another backup I am
getting a "The media is write protected, (error code 0x80070013) " error. I have even tried to reformat the external drive with no luck in solving the problem. In doing some web searching I did come across someone with a similar problem running a Windows 7
beta last year that appeared to have be fixed by an beta update. Any help would be appreciated. Thanks

Hi,
Please try this:
1)
Click Start and type: diskmgmt.msc in Start Search box.
2)
Open Disk Management, right click on the external hard disk.
3)
Click Properties and click Policies.
4)
Check “Better performance”.
5)
Click OK.
Then backup again.
Resource:
When I tried to backup my files, I recieved an error
(0x80070013) saying that media is write protected

How to detect the key enter with a numerical control without using loop event?

I want to accept a numerical value only when the key enter is pressed, but without using the event. How to detect the char "enter" with a numerical control?
Thanks!

When the user edits a numeric control with a keyboard, its property "key focus" is true. When the user hits enter, key focus becomes false. Poll the property to latch the control valuse at the true-false transition. That won't work if the user modify the control using up and down arrows.

How to detect the iPhone Date and Time

Hi guys,
I am new this plateform and I am working on an iPhone application in Objective-C. I need to detect the date and time of iphone clock in the objective-c.
Please let me know if anybody knows how can I do it.
Thanks,
Ranjit Singh

Ranjit,
Be sure to consult the docs for the iPhone SDK. If you are running the simulator, you probably have access to frameworks and classes not available on the phone itself. The iPhone docs don't show NSCalendarDate as a valid class for iPhone (but it exists for MacOS). I think you'll need to use NSCalendar if you wish to have it run on the device (and not just the simulator).
Do you have a device you are testing on? It would be good to verify this (I don't and therefore must use the simulator).
Cheers,
George

How to detect the two Enter in HTTP Request Line"

I'm writing a HTTP Server. I want to ask how can I detect the "two <Enter> press" when the client finishes his request.
Suppose the client typed the following:
GET /xxx/index.html<ENTER>
<ENTER>
(Response header and Entity body here)
if the user typed:
GET /xxx/index.html<ENTER>
If-Modified-Since:xxxxxx<ENTER>
(Response header and Entity body here)
How can I solve the above two cases?
I have used the folowing statement but it fails, why?
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream( )));
String request = null;
request = in.readLine();
Another problem in my WebServerThread is the output to the screen as shown in below:
java.net.SocketException: Connection reset by peer: JVM_recv in socket input stream read
at java.net.SocketInputStream.socketRead(Native Method)
at java.net.SocketInputStream.read(SocketInputStream.java:85)
at java.net.SocketInputStream.read(SocketInputStream.java:63)
at java.io.InputStreamReader.fill(InputStreamReader.java:168)
at java.io.InputStreamReader.read(InputStreamReader.java:244)
at java.io.BufferedReader.fill(BufferedReader.java:134)
at java.io.BufferedReader.readLine(BufferedReader.java:294)
at java.io.BufferedReader.readLine(BufferedReader.java:357)
at WebServerThread.run(WebServerThread.java:28)

A second <ENTER> following directly after another will appear as empty line when you use in.readLine().
