Then a function afterLogin() will be called that resides in the CTRL Lib login.ctl. This lib can be defined in the project itself to allow opening its own modules after login. In the dialog (3rd parameter), you can display your own gif logo that must be located in the pictures directory.

If you want to use your own logo in the login dialog, first copy it to the project directory. Then enter your own parameter for the gif image in your login module, for example, the login.pnl with the panel attributes > On opening.
