filelock

I've upgraded a WCF project running 3.5 vs2008 to .net 4.0 vs2010 and run into a problem. When compiling from vs2010 an assembly in my service implementation project is locked by devenv.exe (note no debugging - only compiling). The assembly is released when vs2010 is restarted and can be compiled once, after each restart. What I've tried to far: Insert PreBuild event to unlock the assembly removed assembly version wild card Disabled source stepping stopped windows search stopped IIS quit vs2010, removed sln.suo and bin/obj folder Read blog and SO posts for 3 days now :) Removed all references

How does Windows remove locked files in the next reboot when you uninstall a program? Maybe with some kind of scheduled process? The uninstall process uses MoveFileEx with the MOVEFILE_DELAY_UNTIL_REBOOT flag set, which indicates that the operation shouldn't occur until reboot. Leaving the lpNewFileName parameter NULL indicates the file should be deleted: If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT and lpNewFileName is NULL, MoveFileEx registers the lpExistingFileName file to be deleted when the system restarts. If lpExistingFileName refers to a directory, the system removes the directory

So i used the following to create a lock on a file so that I can edit it exclusively: File file = new File(filename); channel = new RandomAccessFile(file, "rw").getChannel(); lock = channel.tryLock(); Now I have a 2nd thread want to access the same file - just to read, not edit. How do i do that? Right now the 2nd thread will throw an io exception and inform me the file is locked. Is this doable? Any suggestions? Thanks You could try asking for a shared lock using the three argument version of tryLock. Here is the appropriate javadoc: http://download.oracle.com/javase/1.4.2/docs/api/java/nio

For reasons that I will not explain (because people will direct their responses at the other topic, instead of my problem at hand), I need to know how to determine whether or not my H2 database is locked. Using Java code, how do I determine whether or not the lock file exists on my database? For others reading this question I need to explain why you you shouldn't do it yourself, and let the database detect itself whether it is locked or not. First of all, database file locking is an implementation detail that can and will change in future versions of the database. Then, there is a race
