Hi all.
I have a COM DLL that I want to pass back an image stream to an ASP page.
I am doing this via a delphi CGI app, well it passes back an image in the
response object...and works fine, but will not be able to use this method
now which is a pain.
I am doing :-
var
mMemStream : TOLEStream;
oVar : OLEVariant;
img : TImage;
Stream: IStream;
begin
mMemStream := TOLEStream.create(Stream);
img:=TImage.create(nil);
img.picture.LoadFromFile('c:\Chart2.bmp');
img.Picture.Bitmap.SaveToStream(mMemStream);
move(mMemStream,oVar,iFileSize);
BUT...when it does the MOVE I get a "Catastrophic Error" or it just craps
out...I tired to use a TMemoryStream too, and got the same result.
Has anyone else done this and can help me out ??
Thanks, Jeremy Coulter
