Why does the database reads GB2312 as pure unicode ?

I try to add chinese characters (GB2312) to the Access database using jsp. I can add to the database but when i try to retrieve it, it returns as pure unicode, as a result, i can't retrieve using my sql query.
Another thing is when i maunally saved chinese characters into my database, it can be saved but when i try to view it over the web using jsp, the chinese characters has been replaced by '?'. Why it that so ?
How do I prevented that from happening ??
Sorry if my question is confusing.
Thank you in advance.

Have you solved this problem? If so, can U pls tell me bcos I hv the same problem.
Thanks in advance

In my events the key photos no longer show up and the picture amount reads 0, but the pictures are still there when I click on that event. Why does the amount read 0?

In some of my events in iphoto no pictures show up in the key photos. In others they do. I just upoaded some and no problem. I noticed that in the lower right corner of each event with no key photo the photo amount reads zero. I click on that event and all of the photos do show up. Does anyone know why this is happening, or have come across this before? Thanks, Daryl

Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.

When use scan mode and FPGA simultaneously, why does the FIFO Read can not be used?

Hello, I am using compactRIO-9025 to do a project and trying to use scan mode and FPGA simultaneously ( Hybrid mode). I have already build a project as the following tutorial.
http://digital.ni.com/public.nsf/allkb/0DB7FEF37C26AF85862575C400531690 and I have NI 9205, NI 9023 in Scan mode and NI 9871 in FPGA mode in the same project.
In the FPGA Target of the project, I add a FIFO and tried to use it to log in data from NI 9871. I wired the module I/O node to FIFO Write in the target vi. However, when I droped the invoke method to the block diagram of the host vi and right clicked it, there is no FIFO Read can be choose. Could you please help me to solve this problem?
Thank you very much!!

I am not aware that using the Scan Engine is blocking any access to a transfer FIFO. But please reread this from your quoted KB:
Secondly, the number of DMA FIFO's that can be used in the FPGA code will be reduced, since the scan engine uses two DMA FIFO's. Most FPGAs have 3 DMA FIFO's, so there will only be one DMA channel left to use in the FPGA code.
This means, you have only a single DMA FIFO left which is either Target to Host or Host to Target.
Make sure that you configured the FIFO to be the correct direction for your needs...
hope this helps,

Why does my card reader not work on my iPad since upgrade?

I use my iPad mini to download photos from my camera when I'm on the road. In the summer I bought the "3 in 1 Card Reader Adapter Cable Camera Connection Kit, 3 Port Card Reader for iPad 4 and iPad Mini by Eurekka" and it worked wonderfully. I was able to download photos (jpg and RAW) directly to the iPad and off the camera, and once home it was a flawless upload to my iMac.
However, once I upgraded to iOS 7 last week I get a message saying the device is not supported. What gives? Will this be fixed or will Apple products only accept Apple accessories from now on?

No but I was just trying to find a way in to your help desk. I didn't find
your web page very helpful in this regard.

Why does the new operating system not delete the moved files from their original location - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it

Why does the new operating system not delete the moved files from their original locations - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it - also, when transferring large amounts of files it becomes a very large problem remembering which files were transferred and which not.

You're going to need to be more specific, as I'm not quite sure I understand what you're talking about.
If you're referring to copying from an external hard drive or flash drive, and you want to actually move files rather than copy them, you can hold down the option key to force it to do a "move" rather than a "copy." This is not new behavior, though... the Mac OS has worked this way as long as I can recall (and I've been using it since 1984).
If you're having a problem with trying to move files from one place to another on a single drive causing them to be copied instead, that is likely because of some permissions issue preventing you from actually being able to move them.

Why does the screen on my iPad mini jump around? Apps open and close, I can't get back to the home screen. Is my mini possessed?

Why does the screen on my iPad mini start jumping--larger, smaller--can't close apps. I reboot and still it happens. Any suggestions?

If the unit has NEVER been jailbroke, first try a system reset. It cures many ills and it's quick, easy and harmless... Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, if you have IOS-7, read this.

Why does the iPhone convert animated .GIF images?

I saved a bunch of animated .GIF files on my iPhone.
When I imported them onto my computer, they were all single framed .JPG files.
Why does the iPhone convert the images, and is there any way to prevent this?
Thanks!

you can play gif in webView ,just the same way you load a jpeg or png..
NSString *path = [[NSBundle mainBundle] pathForResource:@"santa" ofType:@"gif"];
NSURL *url = [NSURL fileURLWithPath:path isDirectory:NO];
/* Load the request. */
[myWebView loadRequest:[NSURLRequest requestWithURL:url]];
the gif that is locally saved will be loaded.

"Why Does The Shuffle Songs Feature Perform So Poorly?"

How'dee,
I have an iPod 160G Classic, I've spent the last 3 months taking my 2,247 "Owned" cd's (I'm a retired dj), an ripped them with identical settings and transfered them flawlessly onto my iPod. I now have a total of 26,311 tracks on my iPod. "FWI"- I tranfered each "Complete" album, no individual tracks... I had been looking forward to being able to Shuffle through my music and not actually listening to individual ablums at a time. I work as a security guard and I am able/allowed to use my iPod via my Bose dock.
I have been listening to my iPod in Shuffle Mode for 3 full weeks now and I am finding that I'm continually listening to the same 30 or so albums out of the full 2,247 that are on my iPod, sometimes it will actually play a song from a perticular album and then play Another track from that same album within the next 10 - 15 tracks!
In the end I'm hearing One New Track that I haven't heard yet every 15 - 20 or so tracks while at the same time I'm hearing tracks from the same albums and or groups throughout the 15 - 20 tracks that have played... As an example, I have 4 albums from the group KISS, I hear tracks from those 4 albums atleast 3 - 5 times every day - day & half... Why does the Shuffle Mode work so poorly? I can't see for the life of me why the so-called "Shuffle Mode" doesn't Shuffle through "ALL" of the 2,247 tracks that are on the iPod.
I've even gone as far as to use a cable to plug my iPod into a regular radio allowing me "Not" to charge my iPod until the battery is almost dead, allowing it to play continuously for my entire 8 hour shift in Shuffle Mode. And then just resume the next shift for another 8 hours, again, until the battery is almost dead. I've gotten around 35+ hours per charge over the last 2 weeks.
"My whole reason for spending $350. on this iPod was so that I could listen to my album collection as though I were listening to a radio... shuffling through "All" of my tracks. I'm now sitting here kicking myself in the a$$ for seemingly wasting my money..."
Any insight would be appreciated.
And just to let it be known, I have attempted to play tracks manually just to see if they are even workable transfers and I haven't come across any problems with the music that I put on the iPod.
The ToxicOne...

It is true - "random" does not mean that you should not hear two songs from the same album (or artist) in close proximity. However, as the number of albums increases, the likelihood of hearing multiple (sometimes three or four) cuts from the same album decreases. And the chances of this happening EVERY time a new shuffle is started is even less likely. Comparing flipping a coin (a 0.5 probability of any given result) to a library with over 2000 albums (a .0005 probability of a track from any given album) is comparing apples to oranges. Also, given one of the posts above which indicated hearing the same *progression of songs* indicates that the mathematical algorithm used by Apple to simulate randomness (as there is no such thing as true randomness in computer programming) is just not up to snuff.
