Hi,

I'm a relatively casual programmer (beside being a vet) so i might be asking things that are obvious to most. I work in DTP 2006 and I'm really interested in getting mem leakage info on partial program actions.

I don't understand quite how to get things going. What I did was add denomo.pas to the project, manually move it to the top of the uses list in my project file and start compiling. Every subsequent file reported missing when compiling I added manually:
DenomoMemHooker ,
DisAsm32,
Win32Hook,
DenomoUtils,
DenomoHost
until I came to jcldebug which doesn't seem to exists anywhere.

I already found out you have to
disable UseJclDebug in denomo.inc like this:
{.$define UseJclDebug}

Hello,

Maybe I should add instructions on setting the paths. :-)

You need to add paths where Denomo sits in.
In Delphi IDE, click menu Project, then Options, in the pop up dialog, select the tab Directories/Conditions, then in the field "Search path", add the path where Denomo is in, and also add the path where Denomo\Disasm32 is in.
You can temporarily disable JCLDebug by disable the option "UseJclDebug" in Denomo.inc by adding a dot before "$define".
That line should look like
{.$define UseJclDebug}

Then your project can be compiled.

However, there has been some user report bugs on D2006 and D2007 in the Borland newsgroup, I will check and fix the bugs as soon as possible. So if you get errors when running, be patient, bug fix will come soon.

continuing my monologue:

I get the next error in my program after inc session leak end
(Delphi Turbi Professional 2006)

End incremental session leak dectection at group 1
//=========================================

Hello,

To avoid that range check error, you should disable range check in your project.
In Delphi, go to menu Project, then Options, in the "Compiler" tab, in the "Runtime errors", clear the check mark of "Range checking".
I will investigate to see how to avoid that error.

About the output information.
Such line
01E7F8E0 BlockSize: 116 Class: TBitmapImage
Means an object of class TBitmapImage is leaked and the object memory pointer is 01E7F8E0.
Following lines such as ST: 0046F0CF is the stack trace. The hex number is the address where the function that allocates that block of memory.
Hex number is meaningless to you, please download JCL and enable JCLDebug so you can get readable source line information. Google for "Delphi JCL" for download.

And such line
06479D90 BlockSize: 308 GETMEM
Means a leak is a raw memory block which is not an object, the memory block address is 06479D90.

Thank you very much for you feedback, seems I have much to do on the documentation. :-)

BTW, you are not monologue, I've replied your previous message.

Thanks for your kind replies.
When I remarked monologue I was still ignorant of your first reply. Also it was not meant negative but more apologetic to your forum for ranting on by myself.
Thanks for your efforts with the program I will give it a thorough tryout.

Hello, Hans,

No need any apologetic.

Denomo, the site, and the forum are very new yet.

Your any feedback, bug report, wish list are quite appreciated.
