If you really tried, consider getting a book about VB and giving it at least a skim before tackling a project. Teaching yourself from scratch is hard because there's a baseline skillset that is required to even approach the documentation. It's like teaching yourself trigonometry before learning addition. If you didn't really try, stop lying.
Besides the Text property, the only piece of the puzzle that could be missing is how to make a string based on some variable values. This is usually called "string concatenation" or "string formatting" depending on how complicated it is. I'm not going to talk about string formatting because it's the more complicated case.
Dim stuck As String = "Left " & "right"
After this executes, the variable stuck
will contain "Left right". You can do this with variables as well so long as they are strings:
Dim left As String = "Hello "
Dim right As String = "world"
Dim joined As String = left & right & "."
After this executes, the variable joined
will contain "Hello world."
See if you can figure out how to set your form's text to a string that contains the document title from there.
