Sorry this is not at all clear what your question is, what you are trying to do, what code you have written or what your problem is.

Now I have a program where I add the path to the folder. Folder paths are stored in MySettings. I want the selected button was blocked by me if it is not signed no path in MySettings.

Okay.... that is not any more clear. Please use the "Improve question" link to update your question with the code that you have written and a clear description of a problem. We have no idea what "the selected button" would mean to you or what "if it is not signed no path in MySettings" would mean to you. It might also help you to use google translate so you can type your question out in your native language and paste the translated English here.

Let's leave the subject of the button. It is important for me is that I can't use "LogInListBox1.Items.Add"

I have the code - LogInListBox1.Items.Add (Query ("SELECT name FROM busO1 WHERE ID = '" & i & "'"))
and I get an error - 'Add' is not a member of 'System.Array'.

Sorry, I would have no idea at all what "LogInListBox1" is but the error message is perfectly clear. A System.Array does not have an Add method, you would have to use the SetValue method.
