Hi all
We are moving to D2009 from D2006 and I have a small problem regarding
printing with QuickReport.
When I want to call the preview-method I get an EInvalidGraphic with the
message "Metafile not valid".
It's a simple report with no dynamic parts and just "basic" components.
I can preview it in designmode and I can print it just fine.
It's just the preview in runtime that doesn't work.
This is where it all happens. In the last end else and the call
"result.LoadFromStream(Stream)".
function TQRPageList.GetPage(PageNumber : integer) : TMetafile;
var
Dummy : longint;
TempStream : TMemoryStream;
aByte : byte;
BytesToGet : longint;
I : longint;
begin
if PageNumber > PageCount then
result := nil
else
try
LockList;
SeekToPage(PageNumber);
Stream.Read(Dummy,SizeOf(Dummy));
Stream.Read(Dummy,SizeOf(Dummy));
BytesToGet := BytesToGet-Stream.Position;
result := TMetafile.Create;
if Compression then
begin
Stream.Read(BytesToGet,SizeOf(BytesToGet));
TempStream := TMemoryStream.Create;
aCompressor := TQRCompress.Create(Stream, false);
for I := 1 to BytesToGet do
begin
aCompressor.Expand(aByte);
TempStream.Write(aByte,1);
end;
aCompressor.Free;
TempStream.Position := 0;
result.LoadFromStream(TempStream);
TempStream.Free;
end else
result.LoadFromStream(Stream);
Stream.Read(Dummy, SizeOf(Dummy));
finally
UnlockList;
end;
end;
Anyone who knows something about this?
Somebody has reported a similar problem to Codegear.

I have tried the solutions mentioned in the bugreport but that doesn't
solve my problem.
