Maintenance

[domentarion]

Hello Guys,

I have a problem. I can't figure out how i most do something. I shall explain what is my problem

First i gonna tel you about my program :

I have a program that loads a splash screen. During the splashscreen the program do some validations :

1. Check if the computer has connected to the network
2. Check if the program has a configuration file(tekstfile)
3. Checks the configuration file is it has a databaseserver, databasename , username and password
4. Check is it can reach the databaseserver
5. Check is the database exists
6. Check if the username and password is correct

If something is wrong the program gives a specific message. Now i wanne add something that checks if there is a maintenance , but i don't hava any idea how i can do this ? Does somebody have a idea?
