Hi all,
I implement all importmant controls event i can do in my form,
like Datasource, TAdoQuery, TAdoConnection. I test them one by one.
all event they have are overrided as follows:
...
    if ( myEdit->Text.trim() == "-" )
        ShowMessage( "this is control event name." );
...
I still cannot catch that Exception:
    "-" is not a valid floating point value for fiedl "xxxxxx".
please help me.

Thanks for advance.

Wu JianHua.
