Error in dbMonitor 3.02

Error in dbMonitor 3.02

Postby hannes_a » Sun 25 Jul 2010 21:57

I get often this error in dbMonitor 3.02 dialog
Invalid parameter. (d:\Projects\Delphi\ThirdParty\VirtualTreeView\Source\VirtualTrees.pas, line 15119)

I guess with the line number is will be not so difficult to solve this issue

thank you

Thank you for your report. Could you please describe the situations in which you are encountering the problem so that we are able to investigate it in details? If possible, please send us a sample project and the scripts for creating the database objects with which the problem can be reproduced.

Till now, I didn't found a strictly reproduce able situation. I only can tell you what I use.
I use a Win32 app with ODAC, a Win32 service with ODAC and a ASP.NET web app with dotConnect, all of these connect to an Oracle db and use dbMonitor at the same time. But I never see it life raising the error, only if I switch with the task manager to dbMonitor, I see minimum 10 such Error dialogs.

Sorry, I don't know more information for you. If you provide me the source code, I can probably debug and solve it for you.

The code line specified refers to a tree component and can be reached in different situations. Could you please try to reproduce the problem and check the latest commands logged in dbMonitor? We cannot reproduce the issue in our environment.

Since version 3 of dbmonitor is out I see this error, till now, it wasn't reproduceable for me, but I will look, if I can.

What version of VirtualTrees.pas do you use ?
I see the lastest it
unit VirtualTrees;
// Version 5.0.0

and I see from version to version, line 15119 is on different positions

Just as a note:

I did encountered the error also several times.

But (until now) I never got this error when the "Show Namespaces" AND "Show Parameters" was selected....
Don't know if it could help.

But you have already reproduced it, so it will get solved
:D

Maybe just some extra remark (feature request) --> is there a possibility to add/view in DBMonitor some info about the current host from which the SQL-debug info is coming.

This could be really handy when I use the remote OracleMonitor who send info to a centralized DBMonitor-instance running somewhere.
But I only see the process-name (appName), but when using same app on different places, there is no easy view of which process comes from which host. So maybe adding some notion about the source-pc (IP or name or ...) could just be enough.

But it has to be possible of course.


Greetings,
Fred

We have fixed the bug with assertion failure on show call tree in dbMonitor (the "Invalid parameter" exception). I will post here about the progress on other requests and information about the new build of dbMonitor.

also from my side: thanks for the bug-fix and the extra feature.

Indeed, the download page in the secure-area does not show any download link. But becaue the monitor is a free tool, it is downloadable from the product page.

Thx
