[jarkol]

Hi
I've problem with load zcd files. When file have about 20 MB (I don't know exactly whitch size is to big) and I try to load it I got an error with VCL50.bpl and the program whitch I use crushed.
Error: Access violation at adress XXXX in module VCL50.BPL.

I don't know where is the problem, but I found that everything stops in LoadFromStream.

Sorry for my english and thanks for help.

Try to load it to precompiled PivotCube's demo. Save your data to file, rename it to cubedemo.cub/cubedemo.xml, load it to demo app, then try to load that (map) zcd file.

Hi again
Thanks for reply.
I have tried what you wrote but Demo application doesn't work with my cube. My cube (change name to democube.cub) have 117 MB and when I use Cube->Load file demo application doesn't react. I think application doesn't load this cube.
When I open oryginal demo and my cubes in text viewer a get something like this:
oryginal demo cube: 0 C U B E D E M O @ P I V O T C U B E _ T R I A L  1 0 . 7
my cube:  O L A P  1 0 . 3
Do you have any ideas?

Your cube has much lower version number, it may be incompatible with latest zCube.dll. You may look at this viewtopic.php?f=8&t=310 for details

I used older zCube.dll and now it works, but when I loaded my map I got "Out of memory". I tested it on two different computers with 1 GB and 2 GB RAM. Do you have any ideas?
Could you tell me, how does loading map works? When I open my maps in demo application, it load it very long and my memory use still increase.

The speed of loading map depends on number of items in dimensions. As user can change hierarchy in dimensions, add custom grioups, setup filters etc it force map to load and check each dimension items for its place. Also, the actually loaded cube may be diffrent from one used for map create so some items may absent in cube but present in map and vice versa. That all slowdown loading process.
If you not need in support of these abilities you may create maps with parameter SaveDimensionData = False, it will avoid items stuff and perfomance will rapidly increased.

Also, I suggest you use SaveToXML method for maps which can be used for exchange or long term keep and binary (SaveToStream/File)- only for local, fast save/load (during in single session).
