VirtualBox - error after moving VDI file - Failed to open the hard disk

I was running out of disk space, so I needed to move virtual disk drive (VDI file) to another partition. As normally (read: in other virtualization tools) I removed/detached VDI file from virtual machine, moved it to new partition and added to existing virtual machine in this step error occurred:

"Failed to open the hard disk filepath.vdi
Cannot register the hard disk filepath guid because a hard disk different filepath.vdi with UUID guid already exists.guid "

Solution:
Run following command "vboxmanage internalcommands sethduuid filepath.vdi"

PS vboxmanage.exe is normally located in "C:\Program Files\Oracle\VirtualBox"

ADT17 bug: "java.lang.NoClassDefFoundError"

After successful build of Android application it crashes with error:

java.lang.NoClassDefFoundError: com.google.android.apps.analytics.GoogleAnalyticsTracker

Or some other class. Probably you have installed new ADT17 update. ;)

Resolution: Move \lib to \libs folder.

Database mail not working - restart/re enable service broker

Situation:

- in event log "An error occurred in Service Broker internal activation while trying to scan the user queue 'msdb.dbo.ExternalMailQueue' for its status. Error: 1222, State: 56. Lock request time out period exceeded. This is an informational message only. No user action is required."

RAISERROR raises error - not expected behavior on SQL 2005

Description:
We all expect that RAISERROR raises error, but not like this one:

Script:
RAISERROR ('Error', 16, 255 );

Output:
Invalid value 255 for state. Valid range is from 0 to 127

Value for state can be from 0 to 255, according to BOL:
"state
Is an integer from 0 through 255. Negative values or values larger than 255 generate an error.
If the same user-defined error is raised at multiple locations, using a unique state number for each location can help find which section of code is raising the errors."

Solution:
- check SQL Server version (@@VERSION) and if it's 9.0.1399 (Microsoft Sql Server 2005 RTM) it's really time to apply some service pack. SQL 2005 RTM was released on November 7, 2005! ;)

- http://support.microsoft.com/kb/2507769/ (Cumulative update package 3 for SQL Server 2005 Service Pack 4)

Appendix:
- error in German language version:"Der Wert 255 für den Status ist ungültig. Der gültige Bereich liegt zwischen 1 und 127."

If you have, and no backup etc, read following articles:
