I used Tommys Resource Compiler 1.3 to compile several BMPs and 2 GIFS into a resource file for my program, resource file size: 843Kb.

When i run my program using the resource file it cosumes: over 20Mb in RAM.

But when i use the original bmps and gifs in the same directory calling them directly. It Only uses 5.6 Mb

Is this a bug or i am doing something wrong?

Ok, i have also tried: HASM Resource Compiler v1.0

And I left out the gifs, and just complied the bmps, same thing is happening. Roughly about 20Mb RAM being used Shocked

Is this a bug can anyone confirm, give a idea to remedy !!!

Can you give a few more technical details, i.e. how much RAM you have,
your computer manufacturer, processor speed etc., which could turn out
to be useful. Wink

Also, how many bitmaps are you putting into the resource file and how
large are the bitmaps all together without being in a resource file. How
are you measuring the memory loss?

OK, STATS:

I am creating a resource file called: cpc.dsr

There are: 25 Bitmaps Totaling: 797Kb (not compiled into resource file)

I am using Windows XP Pro, 240Mb Ram, 40Gb Hard Disk. 1.2Ghz Processor

I am using Windows XP Task Manager to register the memory being used.

Thanks for any help !, this is really messing my program up, Size Wise !(running)

OK, just to be sure, let's test this. I'm not exactly sure if there's 1000 bytes
in a MB or 1024 or something. But let's use 1024 because I think that's
right. Wink

Use the following code; make sure to show the dialog, then post the
results:

There are 1024 bytes in a KiloByte(Kb) and 1000 KiloBytes in a MegaByte(Mb). Smile

OK, when using the Resource file:

There was a 16.18359375 MB loss while using your program.

When calling the bitmaps and not the resource file:

There was a 4.91796875 MB loss while using your program.

Nathan (does this help ?)

... So that means it only takes 4 MB of RAM, doesn't it? Confused

Another thing the program loads faster when i do not use the resource file. (I use the bitmaps)

I can't figure it out !, it should not really consume that much resources should it ?

The main reason i want to use the resource is so that no-one can change the bitmaps my program uses, and it's tider !

I don't understand how the resource file is getting loaded into memory
anyway. Your app should only be extracting images from the resource file
as they are needed. The only thing I can figure, and I hope I'm wrong, is
the the routine that extracts the images from the resource file is not deleting
the object handles. At least if VDS were written in C/C++ that would be a
possible answer but since it's written in Delphi, I can only speculate.

lol, must be braindead. Smile

Forgot to mention that the following line:

Rubes_sw · Posted: Thu Mar 20, 2003 4:05 pm Post subject:

%%start_mem = @sysinfo(freemem)
returns size as Kb (as per VDS help File)

Nathan

Any help will be great on this problem !

Delphi doesn't extract the images/files to disc. It uses a TStream to read the data into a stream and sends the binary information directly to a TImage etc so it loads the bitmap/gif etc. It's a direct binary transfer from file to control.
Why not try to use the resoruce compiler that comes with the registered users pack? It's a simple commandline compiler and I know it works error free. It supports any type of file as well.

I stand corrected twice. Embarassed

But you still aren't getting an accurate MB reading
by dividing it by 1024. If @sysinfo(freemem) returns in Kb, it must be divided
by 1000 to get Mb.

And PGWARE thanks for the Delphi lesson, I wasn't aware that that is how
Delphi deals with the resource extraction. Smile
