If you don't do a re-raise, I don't understand where the dialog box comes
from, since you're catching all exceptions...

Hi Michael,
no, i did not re-raise there.
I want only a silent flag. This should done by the Result:= false in the
calling function.

On my Raspi/Debian i got on a TMSSQLConnection a messagebox if the
server is not reachable. The connection is not my problem, but i am not
able to cach this exeption silent without poping up this messagebox.
The problem is, the messagebox pops up and want an OK or ABORT.
In my code i catch the exception, set a flag and reraise
try
if IsOk then AConnection.Connected := true;
except
on E : Exception do begin
IsOk:=false;
raise;
end;
end;
The calling function does this
Quote
Result := false;
try
xxxxxxxx(IsOk);
Result := true;
except
on E : Exception do begin
.........
Do you also re-raise here ?
end;
end;
So the exception should silent catched and i can handle if a connection
is ok or not.
How can i avoid the unwanted box ?
Normally catching the exception is enough.
Michael.
