Well i dunno if this goes here, anyway i try to explain.

I want to know how to write a program that asks for the password and then calls the actual program, which would be "hidden" in another folder.

Is there somehow i cud make it and which language shud i be using and u got any tips how i would do it?

You could do it in any programming language if you had the know how, although many developers find that an easier solution is serial-key and activations.

This may seem like a lot more but you don't have to worry about encrypting passwords in Databases and calling them, then checking if the string the user input matches the encrypted string within the database therfore having to decrypt it and check.

Then you have to excecute the program so it's easier to create an array of random strings and inserting them in a database for everyone.

I don't have enough programming experience to tell you much more i'm afraid.

Or just store the encrypted password in the database and encrypt the input password and match them there
