• Can I create an ASP.NET ImageButton that doesn't postback?

  - by Giffyguy

  I'm trying to use the ImageButton control for client-side script execution only. I can specify the client-side script to execute using the OnClientClick property, but how do I stop it from trying to post every time the user clicks it? There is no reason to post when this button is clicked. I've set CausesValidation to False, but this doesn't stop it from posting.

• Is using project:permissions in a symfony project safe in a production environment?

  - by mhughes

  As the question states, is this task safe for a production environment? I find the permissions rather permissive, the cache directory is the one i find particularly suspicious. Write and execution permission on a code directory is somewhat suspicious. Cheers

• Limiting JMS Destination Instances

  - by jumponadoughnut

  Is it possible to limit the number of JMS receiver instances to a single instance? I.e. only process a single message from a queue at any one time? The reason I ask is because I have a fairly intensive render type process to run for each message (potentially many thousands). I'd like to limit the execution of this code to a single instance at a time. My application server is JBoss AS 6.0 Any help much appreciated

Is there a elegant way to keep the current execution path of the application to the site-packages directory? Thanks

• Infinite throwing in constructor

  - by Mikulas Dite

  What happens to a php script which goes like this? class FooException extends Exception { public function __construct() { throw new FooException; } } It's probably same as while (TRUE) { new Exception(); } It simply time outs when execution time is exceeded, or fails with some fatal error?

• Unload event for the default AppDomain?

  - by Zor

  Hi, I need to have an event fired whenever any AppDomain unloads - including the default one of the process. The problem with AppDomain.DomainUnload is that it only fires for non-default AppDomains. Furthermore, AppDomain.ProcessExit has limited execution time, which I cannot rely on. Any suggestions as to how I can achieve this would be greatly appreciated! (Alternatively, having an event fired when a background thread (Thread.IsBackground == True) works too.) Thanks in advance.

• Understanding java's native threads and the jvm

  - by Moev4

  I understand that the jvm is itself an application that turns the bytecode of the java executable into native machine code, but when using native threads I have some questions that I just cannot seem to answer. Does every thread create their own instance of the jvm to handle their particular execution? If not then does the jvm have to have some way to schedule which thread it will handle next, if so wouldn't this render the multi-threaded nature of java useless since only one thread can be ran at a time?

• Adding a clustered index to a SQL table: what dangers exist for a live production system?

  - by MoSlo

  Right, keep in mind i need to describe this by abstracting all possible confidential info: I've been put in charge of a 10-year old transactional system of which the majority business logic is implemented at database level (triggers, stored procedures etc). Win2000 server, MSSQL 2000 Enterprise. No immediate plans for replacing/updating the system are being considered :( The core process is a program that executes transactions - specifically, it executes a stored procedure with various parameters, lets call it sp_ProcessTrans. The program executes the stored procedure at asynchronous intervals. By itself, things work fine. But there are 30 instances of this program on remotely located workstations, all of them asynchronously executing sp_ProcessTrans and then retrieving data from the SQL server (execution is pretty regular - ranging 0 to 60 times a minute, depending on what items the program instance is responsible for) . Performance of the system has dropped considerably with 10 yrs of data growth: the reason is the deadlocks and specifically deadlock wait times. The deadlock is on the Employee table. I have discovered: In sp_ProcessTrans' execution, it selects from an Employee table 7 times (dont ask) The select is done on a field that is NOT the primary key No index exists on this field. Thus a table scan is performed. 7 times. per transaction So the reason for deadlocks is clear. I created a non-unique ordered clustered index on the field (field looks good, almost unique, NUM(7), very rarely changes). Immediate improvement in the test environment. The problem is that i cannot simulate the deadlocks in a test environment (I'd need 30 workstations; i'd need to simulate 'realistic' activity on those stations, so visualization is out). I need to know if i must schedule downtime. Creating an index shouldn't be a risky operation for MSSQL, but is there any danger (data corruption in transactions/select statements/extra wait time etc) to create this field index on the production database while the transactions are still taking place? (although i can select a time when transactions are fairly quiet through the 30 stations) Are there any hidden dangers i'm not seeing (not looking forward to needing to restore the DB if something goes wrong, restoring would take a lot of time with 10yrs of data).

• [ruby] Check if file is a valid image

  Hi all, I'm using rmagick to manipulate image files. I use the ImageList.new on each file to get started. When I apply this method to an invalid image file I get the below error which interrupts the execution of the script: RMagick.rb:1635:in `read': Improper image header (Magick::ImageMagickError) Therefore I would like to be able to check whether a file is a valid image file before using this method. Any ideas? Thanks.
