DBRichView - Application Freeze

Post by nicolas »

i use a TDBRichview in my application, sometimes i can't re-open the form which contains the TDBRichview (application is frozen and to resolve it, i must close the application by killing process).

It seems that the problem appears when in the field (BLOB in firebird DB) there is the value 2 1 0 8 3 0

The version of my TBRichView is 14.7

Did you ever had this matter before ?

Thank for your help.

Example :
-8 1 3
-7 0 -1 0 0 0 0 14737632
-9 2 0 0 0 0 1

The line started from "2" (or any zero or positive number) is simply a text line. It should not cause problem.

There is only one known problem, it happens if:
1) db-components are located in non-main form
2) dataset is active already in designtime
3) the field contains table (TRVTableItemInfo).
A workaround for this problem is making dataset inactive at designtime and activate it in FormCreate.

If this is not your case, can you send me a simple project to reproduce?

Thanks for your response.

To clarify :

I work with 2 TQuery (Master and Detail) located in DataModule. For reasons of performance, Data of TQuery (detail) are loaded in TClientDataSet and i work with the TClientDataSet. At the end data of CDS are saved in TQuery (Detail)

Data of CDS are displayed in TMSAdvDBGrid, the problem occurs when i scroll the TMSAdvDBGrid.

I will try to move the TQuery and CDS in form.

For point 2 and 3, DataSet is not active in designtime and the field doesn't contains table (TRVTableItemInfo)

Regards
nicolas
