It is not possible to start Toad Data Point from the command line as it does not pick up the password.
This is the command line being used:
Toad.exe /TOADUSER=User /TOADPASSWORD=Password /TOADDATABASE=DatabaseName
You always get the toad connection window stating "need more information to connect".
Enter the password in the toad connection window , check "save password" and connect.
Then close Toad Data Point and try to start it from the command line.
Toad will start but you need to have the "Save Password" option selected.
Enhancement request 110990 has been submitted to Development for consideration in a future release of Toad Data Point.
