Hi Michel
I am developing an ActiveX with the purpose of showing images in browser.

Question:

how to open a file using http?

Example:
var
stream: TMemoryStream;
begin
ffileName := '<a rel=nofollow target=_blank href="http://asp007/chapter1.tif';">http://asp007/chapter1.tif';</a>


BeginHourglass;
try
stream := TMemoryStream.Create;
stream.LoadFromFile (ffileName);
PageUpDown.Min := 1;
imageScrollBox.AntiAliased := True;
imageScrollBox.LoadFromStream (stream, ' .tif ', 0);
pageUpDown.Max := imageScrollBox.FrameCount;
PageEdit.Text := ' 1 ';

finally
EndHourglass;
end;

FDirty := False;

/ / ZoomEditChange(Self);

Result := True;
end;

Message comes back informing error when opening the file!

Could it help me?
