Small problem with Chooser

I'm new to Java and ever more clueless about Swing but am trying to learn.
I have implemented a chooser to choose a folder. It works but not exactly as I wish. I supply chooser with the last folder that was previously chosen by the user. Chooser displays that folder and other folders in the parent folder. That's OK but I would like the last folder to be "selected" so the user can just accept it and not have to click on it.
Here's my code:
     chooser = new JFileChooser();
     chooser.setCurrentDirectory(new java.io.File(lastFolderXML.getLastFolder())); // last folder accepted
     chooser.setDialogTitle(choosertitle);
     chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
     chooser.setSelectedFile(chooser.getCurrentDirectory());
How do highlight the last folder accepted?
TIA
Nate

Andrew, thanks for taking time to attempt to help me.
1 The CODE tag: I looked very hard at the thread to find a code tag but couldn't and was wondering why there was none.Which I why I stated +"reply and quote to see the markup"+ . Did you not read that part either? >o(
I (...) had no idea that while heading sizes are available on the page the really important code tag is not.Yes, we all hate that, but Oracle doesn't care. That's why we're usually not too harsh on newbies who don't know how to post code, and why the first reply is usually explaining how to do that. We're much less indulgent when newbies disregard this kind advice...
So far this is the only forum that I've found that does it this way. It would have been very helpful to convey the tag or where it was written up.
I didn't (...) notice that the acronym SSCCE, which conveyed no meaning to me, was a link.I think I explained what it was too: +"Could you post an SSCCE (a short but complete example that fits in one class, and that (...)"+
I was about to comment wittily on how one can miss a link, but I have to admit that this forum's rendering is disgraceful and very confusing...
But I found the problem (...) On Ubuntu it works just as I expected. Next time I have a GUI question I'll specify the OS I'm using.Fine.
Note that if you had posted an SSCCE, several of us would have run it and testified whether it "worked" for them. Myself, had I tried it, would have replied "It works for me on WinXP. What's your OS?".
Glad you found it yourself though. Good luck with Java.
Now to see if I can implement a progress bar.Just in case: in your Swing experiments, make sure you read the Swing tutorial (e.g. for progress bars: http://download.oracle.com/javase/tutorial/uiswing/components/progress.html)

I have a small problem with MSI GF4 MX 420

Hi,
I have a small problem with MSI G4MX420-T(S+C) ( MS-8878 ). Exactly with nVidia WDM Video Capture (universal), which " can't be turned on " by Windows XP.

If you only have 10 seconds of content in a 15-second composition, then you need to either add more content or shorten your composition.
You can shorten the composition by changing the duration in the composition settings.
Since you're obviously very new to After Effects, I very strongly recommend that you start here to learn After Effects.

Some small problems with my new 3G iPhone

Having some small problems with my new iPhone, nothing major, just annoying.
1. When I plug my iPhone in to charge/sync my Adobe photoshop keeps trying to download the photos on my iPhone, which causes an error message from Adobe that it can't download and it stops all syncing and removes my iPhone from iTunes. I have to unplug and reinsert USB cable and sometimes it works ok and sometimes I have to reinsert again. Also when charging, it will disconnect, reconnect and the samething all over again, photoshop trying to get photos and an error message.
2. Can't send e-mails via 3G? Only can get, have to connected to a WiFi to send e-mails, or is this normal?

When your iPhone includes photos in the Camera Roll, it is also detected as a digital camera when connected to your computer, and whichever app you have selected to import photos will automatically launch to import the photos. If you haven't imported these photos, it is a good idea to do so as with any other digital camera. I import the photos followed by deleting the photos from the iPhone after the import process is complete. If I want any of the imported photos available on my iPhone for viewing, I add the photos to an existing album that is selected to be transferred to my iPhone under the Photos tab for my iPhone sync preferences, or add the photos to a new album followed by selecting the album under the Photos tab followed by a sync.
If your iPhone's Camera Roll does not include any photos that have not been imported, Adobe Photoshop should not launch automatically when your iPhone is connected.
I know how to disable the selected application for photo import from launching automatically regardless with a Mac, but not with Windows.
Regarding the sending email problem, who is the email account provider and does the email account provider have an authenticated SMTP server?
Most ISPs block the use of SMTP servers that are outside of their network or not provided by the ISP being used for your internet connection unless the SMTP server is authenticated. When connected to the internet via AT&T's cellular network, it is no different in this regard. AT&T's SMTP server is included and available by default for use with an email account that does not have an authenticated SMTP server when connected to the internet via AT&T's cellular network, but you probably won't be able to use this SMTP server for sending messages with the account when connected to the internet with your ISP via an available wi-fi network - especially if the email account is provided by your ISP.
I access two email accounts with the iPhone's mail client and both accounts have an authenticated SMTP server. I've never had any problems sending with either account regardless the ISP being used for an available wi-fi network, or when connected via AT&T's cellular network.

Smaller problem with handling frame-borders in dreamweaver 8

Hello people
I have build a website using a frameset in dreamweaver 8.
Ewerything works fine, except i cannot drag in my frames when i
re-open the page. I try to select frames in the "windows" bar, and
click on the different frames to make the frame-border appear, but
it does not. Only dotted lines that indicate the selected frame
appear.
mabe there is a button somewhare that make the draggeble
borders come back..
if anybody knows the anwser to my problem - please write.
Thanks

Why? Are you familiar with all the problems associated with
choosing frames
for you layout?
> except i cannot drag in my frames when i re-open the
page
Hmm - I don't understand this. You have created a frameset
page in which
you define your frames, right? And you have saved both the
frame pages, and
the frameset page, right? So, you next open which page? The
frameset? Or
the frame page?

A small problem with my Zen Xtra 60 turned into a bigger problem. Help me save it

What started as a small problem has grown to a big mess. My Zen xtra 60 GB unit started going to "Rebuilding Library" often. With 5000 Wma's on it, this rebuild was taking 30 minutes. So what I attempted to fix with reloading firmware to recognize the new Windows Media Player version, has left me with a dead unit.
I have followed many of the solutions, that have been able to fix other peoples units, but to no avail. While my computer sees the unit, none of the firmware loads will see the player. I fixed what was said in the register. Went through the 4 options of the "Rescue Mode" on the player, followed several of the knowledge notes on procedures, including hooking unit up to a new Dell Laptop. Exactly the same problem happens on a different computer.
I guess my first step is to get the computer to see the MP3 player when I run a firmware install.
Tell me what to do to save my little player.
Thanks Scott

. . . if I don't use [my 30GB Zen Xtra] for day, it re-builds my library and half of the songs are disappeared and also so the "memoryplace" . . .
I've had a similar experience, but to a degree. I've found that if I don't use my <EM>40GB</EM> Zen Xtra for more than one day the player will "re-build" the library... but in my case once the library has been re-built it plays just fine; none of my songs or memory are lost.
Why does the player have to "re-build" the library if the player is not used for a period of time?

Recursive mergeSort... small problem with infinate recursion.

Basically, I have made a recursive mergeSort method, but there is a small problem...im getting stuck with an eternal recursion, which is obviously followed up swiftly by a stack flow error, problem is I cant see where im going wrong...
The error reads, "Exception in thread "main" java.lang.StackOverflowError at part3.mergeSort(part3.java:56)"

Small problem with applescript

Hello Again,
Every day I use a morning script to launch my programs I have to use... and some more things...
Aldo I have a problem with Golive.
When I try to type activate in the editor it makes a bigg A.
Also with cut and past.
and when i run the applescript-program it does all I need ( The golive part is at the end... but when I place it in the middle it's just stops.
I get this fault message : Can't continue <event Coreactv>
and i guess it has something to do with the A-ctivate
Is this a bugg? Or can someone explain this?
I would like to do more after launching Golive..
tell application "Extensis Suitcase X1"
activate
end tell
tell application "Mail"
activate
end tell
tell application "Adobe Photoshop CS"
activate
end tell
tell application "QuarkXPress Passport"
activate
end tell
tell application "Adobe GoLive CS"
Activate
end tell

Some apps don't respond well to tell blocks. I don't have that app to test, but you could try using something like launch "TextEdit" or tell app "Finder" to open posix file "/Applications/TextEdit.app" to improve your results. Sometimes an ignoring application responses block can help too.

Weird problem with choosing song to play

Whenever I choose a song by going to Music -> Artists -> <the artist I want> -> Album -> and then a particular song, it always starts playing the FIRST song on the album, not the song I picked. Same thing happens if I try to play a song by going to Music -> Album -> and then song... whatever song I pick, the Nano will play the first song on the album instead. It's not the end of the world, but how annoying! I have "Restored" my Nano in an attempt to fix this, and at first the problem went away. Just today, though, it began doing it again. My Nano sees very little exposure to the elements or anything one would consider "harsh" use; basically goes from my night stand to work with me at the office and then back again. Anyone else had this issue?
Thanks in advance,
James

Hi
I have a similar problem, however i want to play the first song and it wont. instead it will jump to either track 2, 3 or even 4!, i have had previous ipods none of them doing the same.
Anyone got any ideas for this problem?

Small problems with Image Capture

Hi,
When I upload images from my camera, I have a few problems.
When Image Capture automatically opens, there are two different windows, and I never know which one will open. One has choices like Delete and Eject camera. The other window only has choices like Rotate Right and Rotate Left. Is there a way to get the one with more choices to open every time?
When I eject the camera (either by using the choice from the one window) or by quitting Image Capture and dragging the camera icon in the Trash, I seem to always get a Device Removal warning when I shut off the camera.
Thanks,
Allan

The second problem may be cured by using 'reformat' of the memory card, in the camera.
There may be some corruption in the flash memory; or it may be failing.
The first issue, may be relieved if you can find the correct file plists for Image Capture; and
trash those preferences. If the actual application is somehow damaged, it may be possible
to re-install just that application through use of Pacifist (charlessoft, download) to extract
just that item, from the computer's OS X install/restore disc. Without an 'archive & install.'
Hopefully someone will have exact details from experience; since I've not had similar issues.
Usually, I'd use a free image editor such as ToyViewer for Mac; and also Preview, to edit.
Good luck & happy computing!

Small problem with generics

Hi,
I'd like to get my generic (Hash)Map back from a textfile, for this I have written a method that reads the file and returns an Object. The only problem I have is that I get the error "java uses unchecked or unsafe operations , ..." with the following code:
Map<Character, TransVal> thisIsMyMap = (HashMap<Character, TransVal>) readFromFile("filename.dat");I thought it would be the same as parsing a String (guess not :-) ):
String s = (String) justAnObject;TransVal is a class that contains a BitSet and an Integer.
Any help plz?
(btw sorry for my english :-s )

The reason is that it cannot check, at runtime or at compile time whether or not the cast is valid. It will at runtime check the cast to HashMap (btw, use Map for both the cast and the variable), but it will not check that all the keys are Characters and that all the values are TransVals. What will happen is that somewhere where you actually use the map, if the assumption you are making here is incorrect, there will be a ClassCastException in what appears to be perfectly safe code. If you are positive that your cast is safe, either change the return type of readFromFile or put a @SuppressWarnings("unchecked") annotation on the method and use a java compiler that respects it (eclipse, 1.6, and maybe others, but not sun's 1.5 javac).

Small problem with the Nano 6G, and run workouts

Hello! I have sensor Nike IPod Sport Kit, which is in the new Nano 6G is not needed, because the accelerometer (pedometer) is built into the player and is suitable for running. But buying a heart rate monitor transmitter i is upset that it should only be used with the sensor in the shoe. Because when I connect the transmitter Nike to player Nano 6G, and then connected transmitter heart rate monitor and want to start training, the player Nano 6G is looking sensor in the sneaker, although it could well do without him. Request to developers Apple fix this problem so that you can use the transmitter heart rate monitor with built-in accelerometer in the player Nano 6G.
Sorry for the google-translator. Regards, Alex.

Alex, exactly what I was looking for...
I tryed to get info from Apple and Nike support but seems nobody knows what I'm tolking about.
I hope Apple will fix it on 6th G even if they'll launch the 7th G.

Problem with choose material in a query

hello
I have a simple query and when i'm trying to choose a material in the selection screen it doesn't choose it.
I make a search for a material and then double click on it and nothing is happen.
Any idea why??
thanks

Itay,
It is unclear to me exactly what is the nature of your problem.
I will assume that what you are saying is that you have constructed a query in which MATNR is one of the items you have placed on the selection screen, and when you select something from the F4 help, and you execute the query, that you get no results from the execution of your query.
Assuming that you have defined an output, this means that the way you have constructed your query, no records satisfy the selection criteria.
If the above describes your problem, then the next step is to examine the infoset. What kind of infoset are you using? Direct Read, Join, or LDB?
Regards,
DB49
