Subject: Re: can't load MemoryStream with TImageScrollBox
In reply to: Martin Diehl 's message, "can't load MemoryStream with TImageScrollBox" on 14:09:35 03/12/03 Wed


Hi Martin,

That is strange. A common error is that the stream is not positioned at the beginning.

Try,

Stream.Seek( 0, soFromBeginning);

before LoadFromStream.

Best regards,

Michel
