Problem loading from blob field

[LateralLeap]

I have been using TDBRichView without problems

I now need to load a TRichView component from same blob field that I have been using with TDBRichView

The code I am using is as follows:
try
BlobStream := MyQuery.CreateBlobStream(MyQuery.FindField('SummaryDescription'), bmRead);
txtSummaryDescription.LoadTextFromStream(BlobStream, 0, 0, False);
txtSummaryDescription.Format;
except
end;
FreeAndNil(BlobStream);

I get rubbish in the control even though the content is same as I was loading with TDBRichView

I have an RVStyle compoennt associated with the TRichView component

The content was originally created in MS Word and pasted into the TDBRichView component

LoadTextFromStream loads plain text, but the most probably document in the field is not saved as a text, it is in RVF or RTF format (default is RVF, see FieldFormat property).

So use LoadRVFFromStream, or universal method LoadFromStream (it autodetects format of the stream data)

For some reason the following code works but not sure why my original code did not.

try
BlobStream := TMemoryStream.Create;
TBlobField(MyQuery.FindField('SummaryDescription')).SaveToStream(BlobStream);
BlobStream.Position := 0;
txtSummaryDescription.LoadFromStream(BlobStream, rvynaNo);
txtSummaryDescription.Format;
except
end;
FreeAndNil(BlobStream);

LoadFromStream autodetects the stream format.
