If I've understood you correctly, I think the following will work:
Dim input As String="N14G73X315.2Y83.7I40.0J6.4A0.0H3K75T11F5M0C0.0"
Dim matches = System.Text.RegularExpressions.Regex.Matches(input, "\w[0-9.]+")
Dim parts = Matches.Cast(Of System.Text.RegularExpressions.Match).Select(Function(p) New With {.Key=p.Value.Substring(0,1), .Value=p.Value.Substring(1)}).ToDictionary(Function(p) p.Key, Function(p) p.Value)
txtX.text = parts("X")
txtY.text = parts("Y")
etc
We use a regular expression to split the string into groups of a single letter followed by a number including an optional decimal point. We then use Linq to turn this into a dictionary of numbers (well string representations of numbers) keyed on their corresponding letter from the input. You can then pull these from the dictionary to set each text field
You could also use capture groups on the regular expression instead of splitting the output in the linq statement
