Number code style

Hello
I have a problem with the use of the component DBRichViewEdit. If I save some basic information when loading the values I have a format that is applied at the opening of the datasource
For example, this value cannot be loaded correctly, the text is center and blue
2 00 01 17 300 299
While it works very well
2 10 01 17 300 299
I've not found property in the component to work around the problem.
Thanks

Do you want to change font and paragraph properties of the whole document on loading

I didn't want change anything, I just want to load 2 00 01 17 300 299 in my DBRichViewEdit. Data is correctly saved in database, but when I load it I can't see my number

When I load this number, my cursor is at the center of the DBRichViewEdit, and when I write the text is blue and bold

Probably, documents are stored in the database in RVF format without styles. So, when loading, existing collections of text, paragraphs and list styles are used.
Right click DBRichViewEdit component at design time, choose "Settings" in the context menu. Set "Allow adding styles dynamically" (or "Allow adding styles dynamically + style templates" if you need real styles, like in MS Word).
Make sure that your DBRichViewEdit is connected with its own TRVStyle component (if you have multiple editors, connect each of them to its own TRBStyle component).
Resave your documents in database, assigning the proper font and paragraph properties.
Does it fix the problem?

Hi
No I have again the problem.
My DBRichViewEdit is connected at the TRVStyle.
I add the numer and save it to database with text(max) field.
When I load this value, I didn't see it, my cursor is at the center of the RichView and when I write the text is bold and blue.

If this is a field for text, especially Unicode text, it cannot contain binary data like RVF, so document can be damaged.
Please save field content to a file and send to me.
You can do it using this code:
Code: Select all
var Stream: TMemoryStream;
FileStream: TFileStream;
Stream := TMemoryStream.Create;
(Table.FiedByName(FieldName) as TBlobField).SaveToStream(Stream);
Stream.Position := 0;
FileStream := TFileStream.Create(FileName, fmCreate);
FileStream.CopyFrom(Stream, 0);
FileStream.Free;
Stream.Free;

Summary of our conversation: the component mistakenly detected RVF format in this sequence of numbers. A fixed version is uploaded, RVF detection is more strict now.
