• Acquiring drive names (as opposed to drive letters) in Java

  - by Mattijs

  Hi, On my Windows machine, my main hard drive has the letter C: and the name "Local disk". To list the drive letters in Java on Windows, the File object has the static listRoots() method. But I can't find a way to acquire the drive names (as opposed to the drive letters) on Windows. Has anyone tried this before? Thanks, Mattijs

• Load image from string

  - by zaf

  Given a string containing jpeg image data, is it possible to load this directly in pygame? I've tried using StringIO but failed and I don't completely understand the 'file-like' object concept. Currently, as a workaround, I'm saving to disk and then loading an image the standard way: # imagestring contains a jpeg f=open('test.jpg','wb') f.write(imagestring) f.close() image=pygame.image.load('test.jpg') Any suggestions on improving this so that we avoid creating a temp file?

• Read/Write Excel Files Directly To/From Memory

  - by Corey O.

  Several people have asked, in a roundabout way, but I have yet to see a workable solution. Is there any way to open an excel file from directly memory (like a byte[]) ? Likewise is there a way to write a file directly to memory? I am looking for solutions that will not involve the hard disk or juggling temporary files. Thanks in advance for any suggestions.

• Windows-7 Ultimate 64 bit wont connect to my wired/wireless networks.

  - by A302

  Windows 7 Ultimate 64 bit. Everything was working fine & then just stopped working. The nic card Realtek PCIe GBE Family Controller is enabled but does not connect to my router (cables & router ports are good). Wireless Atheros AR5007EG is enabled but the connection is limited (encryption type / key have been verified). A laptop running XP can connect both wired / wireless. SSID is not being broadcast, connect to network if it is not broadcasting is checked. Have checked services.msc for Bonjour & did not see it listed. Network & sharing center does not list any active networks. Device manager lists both devices as functioning properly. Router configuration has not been changed. Virus scan has not found anything. I would like to fix this rather than using Acronis to do a system restore. Thanks in advance for any advice offered in solving this. 26 Jan, the nic card & wireless are working using PCLinux OS Live CD. It appears that the problem is Windows 7 related.

• SQL Server insert slow

  - by andrew007

  Hi, I have two servers where I installed SQL Server 2008 Production: RAID 1 on SCSI disks Test: IDE disk When I try to execute a script with about 35.000 inserts, on the test server I need 30 sec and instead on the production server more than 2 min! Does anybody know why such difference? I mean, the DB is configured in the same way and the production server has also a RAID config, a better processor and memory... THANKS!

• Copying files to my laptop makes them locked

  - by John

  When I save files from e.g. remote desktop or from an email (outlook) attachments, or from skype even to my local machine they show a locked Icon on the file. Then e.g. SQL Server doesn't let me restore backups as it says the operating system doesn't have access to the file. I've had success fixing this by setting the ownership of the parent folder to my user and then let it apply to sub folders. Also sometimes I need to click - Proerties - Security - Advanced - Change Permmissions, then check "change child permissions..." and apply on the parent dir. I'm using Windows 7 64 bit Proffessional, on HP Probook 4530, and I have a administrator user. This is a real pain to do everytime. I suspect it might be because of HP software that came with the laptop, I think there is drive encryption as part of the protect tools. Although I'm hoping there's something in windows i can set to change the behaviour to not lock these files.

• How do I superimpose one bitmap image on another in GDI+?

  - by Old Man

  Using GDI+ I've made a heatmap bmp and I'd like to superimpose it on top of my bmp map. I've saved the two bmps to disk, and they look good, I just need a way to put them together. Is there any way to do this, perhaps using the Graphics object? How is transparency/alpa involved? I'm very new to GDI programming so please be as specific as possible.

• GUNZIP / Extract file "portion by portion"

  - by Dave

  Hi. I'm on a shared server with restricted disk space and i've got a gz file that super expands into a HUGE file, more than what i've got. How can I extract it "portion" by "portion (lets say 10 MB at a time), and process each portion, without extracting the whole thing even temporarily! No, this is just ONE super huge compressed file, not a set of files please...

• Saving objects in servlet session and java.io.NotSerializableException

  - by EugeneP

  SEVERE: IOException while loading persisted sessions: java.io.WriteAbortedException: writi ng aborted; java.io.NotSerializableException: That means this object cannot be persisted on hard disk. Does it imply that it's not safe to keep in Session objects that do not implement "Serializable"? I haven't heard that there are limitations on saving non-serializable objects in Session object. It simply means that Tomcat will always keep them in memory, right?

• How third-party SQL Server backup tools access databases' files for backup?

  - by snezmqd4

  I'm reading about Red Gate SQL Backup, and I liked the concept of creating a database backup compressed and writing on disk the compressed backup directly without an intermediate SQL Server native backup. And I'm wondering how this type of software make backups. It accesses the database files directly? It uses some sort of SQL Server or Windows API? Windows Shadow Copy?

• Find out how much storage a row is taking up in the database

  - by Vaccano

  Is there a way to find out how much space (on disk) a row in my database takes up? I would love to see it for SQL Server CE, but failing that SQL Server 2008 works (I am storing about the same data in both). The reason I ask is that I have a Image column in my SQL Server CE db (it is a varbinary[max] in the SQL 2008 db) and I need to know now many rows I can store before I max out the memory on my device.

• SQL Server 2008 - Query takes forever to finish even though work is actually done

  - by Brian

  Running the following simple query in SSMS: UPDATE tblEntityAddress SET strPostCode= REPLACE(strPostCode,' ','') The update to the data (at least in memory) is complete in under a minute. I verified this by performing another query with transaction isolation level read uncommitted. The update query, however, continues to run for another 30 minutes. What is the issue here? Is this caused by a delay to write to disk? TIA

Google is not a lot of help here :(

• Hadoop write directory

  - by FaultyJuggler

  Simple question but reading through documentation and configuration I can't quite seem to figure it out. How do I A) know where hadoop is writing to on the local disk and B) change that For initial testing I setup HDFS on a 20gb linux VM - to it we've added a 500gb networked drive for moving towards prototyping the full system. So now how do I point HDFS at that drive, or do I simply move the home directory/install with some slight change in setup and restart the process?

  Looking in Process Explorer it uses; Virtual Size: 550,000k , Working Set: 28000k Why does my simple hello world console app use so much memory?
