Under XE, if you use the layerssavetostream command, it will generate a stream error. I tried it with clean version of XE in a VM and on a different computer. It does work under delphi 2007 though.

Hi Pierre
Can you show me the exact code you are using?
Is this for your code to assign the content of one TImageEnView to another? If so, email me for a code update.

It crashes in my program and the demo that Bill sent me. Simple demo to assign imageen using layerssavetostream.
I get a lot of stream error even when i try to add a box.
I tested it on XP and win 7 with clean delphi XE install.
If you want me to send you Bill's demo i can but just create a button that says imageenvect.layerssavetostream (Imem);
Imem: tmemorystream;
It does not happen with D2007.
Thanks.

Here is the code:
{ Update the preview layers }
var
iMS: TMemoryStream;
begin
iMS := TMemoryStream.Create;
try
ImageEnVect1.LayersSaveToStream(iMS);
iMS.Position := 0;
ImageEnVectPreview1.LayersLoadFromStream(iMS);
ImageEnVectPreview1.Update;
finally
iMS.Free;
end;
end;

Hi Pierre
I cannot reproduce that in v5.1.2 Beta. Do you see this too, Bill?

Nigel,
No I do not and have never had this produce exceptions, even with previous versions.

Ok, i loaded eurekalog and now i get some input. It looks like it has to do with some library compression. Maybe you can decipher the screenshots.

Hi
Please send me the demo. Do I need to add anything to the TImageEnVect for it to happen?

I found a work around. If i put the imagineen library path at the beginning of the list, then the error disappears. So some library are conflicting with some others.

That is not a work-around. That is the way Delphi works. If you have conflicts that you can not resolve then you must put the unit name last in uses.
I am glad you figured it out though...

Bill, just realized that your suggestion would not work. Your demo has no other uses than Imageen and it crashes.

I am sorry but I do not know how to resolve your problem. Are you sure you have not changed the original demo from what it was when you received it? The reason why I ask is I have been using this technique in several applications and I have never seen it cause an exception. Can you pinpoint the line that is causing the exception with EurekaLog or MadExcept? My guess it that the exception occurs in some other event in your program.

I did not change a line. Ran it straight from the zip file. I am doing some troubleshooting. I have a new computer that I just re installed the OS. Installed a fresh copy of XE and only Imageen. No crashes. I am now re adding all the others 3rd party to see if it start crashing. I do not think that is going to happen though.
It looks like one of the 3rd party conflicts with the iezlib library.
So far so good.
Thanks.
