Tstream.seek not implemented...

Because you are using the TStream 'abstract' class - it's not meant to be used directly, It doesn't have .seek() etc implemented.

Check out TMemoryStream which will give you what you're after.

I have unDeleted your post (hope you don't mind) as you are partially correct.

The TStream is indeed intended to be an abstract class but it does have Seek method implemented. Infact they are two versions of Seek method implementations (Delphi XE3). One to work with 32 bit offsets and another to work with 64 bit offsets.
Now these are implemented in such way that one of tem is always called and it contains special code to check if the method was called from base class (raises an exception) or if it was overriden in one of its decendant classes.
This specific code seems pretty wierdly implemented but I sugest you take a look at it as I belive that perhaps such approach might cme usefull when designing classes.
Well not verry likely but still. It doesen't hurt to know

Thanks phibermon

I use TMemoryStream but it does't work so i try this and it works just fine...

instead load image from file with

 
  LoadImageFromFile(SnapImg,myImg);

i loaded directly to TMemoryStream

  strm1.LoadFromFile(SnapImg);

the rest i left just the same and it works...

Thank you...
