QueueExplorer 2.1 - more responsive, better Bulk message sender, multi-queue operations

Dejan Grujic — Wed, 19 Apr 2006 22:23:12 GMT

New version of QueueExplorer is released. Focus of this release is on improved responsiveness of user interface during long-running operations. Progress is displayed, either on progress window or on status bar. Most operations could be canceled.

Using QueueExplorer for stress testing is improved too. Bulk sender (previous Mass paste) takes all messages currently on clipboard and sends them to target queue as many times as you want. New feature is adjustable delay that could be added between messages during Bulk sending.

Last improvement is ability to delete or purge several queues at once. When queues are displayed in right pane list, multiple queues could be selected.

QueueExplorer 2.1 is free upgrade for registered users. You can download it from:

QueueExplorer 1.4.1 - fix for TimeToReachQueue issue

Dejan Grujic — Mon, 14 Nov 2005 07:51:57 GMT

QueueExplorer 1.4.1 fixes potentially very unpleasant problem - sometimes messages would get lost when they are sent to a queue - during paste, mass paste, load or drag&drop operations.

When it happens?
Messages could be lost when they are sent to remote queue and their TimeToReachQueue or TimeToBeReceived properties are 0. Practically it happens if messages stay in queue unconsumed for very long time.

Why it happens?
All QueueExplorer operations are performed using standard MSMQ Send/Receive operations. When message with TimeToReachQueue=0 is sent to remote queue, it would be discarded. Sometimes one or few messages could reach destination queue (depending on exact timing) but following messages are lost. Some of these messages would show up in outgoing queue for a while, but not for long.

How is this fixed?
TimeToReachQueue or TimeToBeReceived are set to 60s if they are below that value at the time of sending.

Queue icons now show its transactional status.
Fixed performance issue when changing queues on Windows 2000.
Supports .Net Framework 2.0 final.

QueueExplorer 1.1 released - .Net view, remote sending, message body operations...

Dejan Grujic — Tue, 21 Jun 2005 20:01:13 GMT

Finally MSMQ messages with serialized .Net objects are not black boxes any more - instead of seeing them in some hex view QueueExplorer allows you to see full .Net objects with all their fields, even private ones! It doesn't matter if binary or Xml serialization is used. All you need to do is tell QueueExplorer where to find assembly with classes.
This is not all of MSMQ troubleshooting features in this release - message body can be saved to disk for further analysis. You can use that body to create new messages.
Remote queues are no more read-only! Yes, you can do all these nice things that used to work with local queues only - send, copy, move messages, even mass paste on remote machines.

What happens when message in MSMQ can not be processed? Most common solution is to put it back to queue and retry later. But if it fails repeatedly following messages will never be processed - queue will be blocked with so-called poison message. How to fight this situation?
