Java - Get Japanese from JTextField and save to File

阅读更多关于 Java - Get Japanese from JTextField and save to File

问题 I am trying to get Japanese input from a JTextField (with the getText() method) and saving that to a File. I am confident that it does get Japanese format from the JTextField since I can append() that String to a JTextArea and it will be in the correct Japanese Format. However, when I try to write to a File it only turns to gibberish! I have tried to use an OutputStreamWriter instantiated with StandardCharsets.UTF_8 and I have tried with a plain FileOutputStream where I send in the bytes from

MySQL Databases Corrupted

阅读更多关于 MySQL Databases Corrupted

问题 We run a MySQL Database 5.5 server on a Windows Server 2008 R2 KVM VPS, where our system automatically sets up new databases for customers as needed. A completely separate drive/partition ran out of space yesterday (had no files associated with the MySQL DB) but seemingly has corrupted the MySQL Database. In reviewing the log files, I can see that the InnoDB is corrupted but cannot make heads or tails of what the problem is or how to resolve it. Can anyone help explain what is these errors

Oracle date corruption during update

阅读更多关于 Oracle date corruption during update

I'm migrating some data from one oracle schema/table to a new schema/table on the same database. The migration script does the following: create table newtable as select ... cast(ACTIVITYDATE as date) as ACTIVITY_DATE, ... FROM oldtable where ACTIVITYDATE > sysdate - 1000; If I look at the original data, it looks fine - here's one record: select activitydate, to_char(activitydate, 'MON DD,YYYY'), to_char(activitydate, 'DD-MON-YYYY HH24:MI:SS'), dump(activitydate), length(activitydate) from orginaltable where oldpk = 1067514 Result: 18-NOV-10 NOV 18,2010 18-NOV-2010 12:59:15 Typ=12 Len=7: 120

How to ensure that data doesn't get corrupted when saving to file?

阅读更多关于 How to ensure that data doesn't get corrupted when saving to file?

I am relatively new to C# so please bear with me. I am writing a business application (in C#, .NET 4) that needs to be reliable. Data will be stored in files. Files will be modified (rewritten) regularly, thus I am afraid that something could go wrong (power loss, application gets killed, system freezes, ...) while saving data which would (I think) result in a corrupted file. I know that data which wasn't saved is lost, but I must not lose data which was already saved (because of corruption or ...). My idea is to have 2 versions of every file and each time rewrite the oldest file. Then in case

GZipStream doesn't detect corrupt data (even CRC32 passes)?

阅读更多关于 GZipStream doesn't detect corrupt data (even CRC32 passes)?

I'm using GZipStream to compress / decompress data. I chose this over DeflateStream since the documentation states that GZipStream also adds a CRC to detect corrupt data, which is another feature I wanted. My "positive" unit tests are working well in that I can compress some data, save the compressed byte array and then successfully decompress it again. The .NET GZipStream compress and decompress problem post helped me realize that I needed to close the GZipStream before accessing the compressed or decompressed data. Next, I continued to write a "negative" unit test to be sure corrupt data
