Hello,
I try to execute an application compiled on Windows XP with Delphi7 and component UNIDAC versione 3.7 on windows 7 64 bit with firebird 2.5.
When I insert and confirm the record than not have a field of type TFloatfield i don't have a problem, when I insert a record with a TFloatfield a see the error: 'Can’t perform operation on active transaction'. Can you help me?
Thank you,
Giovanna

Hello,

This error has nothing to do with float fields. The "Can't perform operation on active transaction" error occurs when you are trying to start a transaction that is already started, or if you are trying to change properties of an active transaction. To solve the problem, you should use the following code:

Hello,
"Can't perform operation on active transaction" is displayed on the screen of my application but from dbmonitor I have a message:
'Unable to complete network request to host 127.0.0.1'
'Error writing data to the connection'
and this appears only when the record contains a TFloatFields...
i dont understand why..
Thank you for all
Giovanna

I cannot reproduce the problem. Please try using the latest UniDAC version 4.1.3 and check if the problem persists. If the problem persists, please try creating a small sample that demonstrates this problem and send it to andreyz*devart*com, including a script to create and fill a table.
