Create strings with all possible combinations that include dot between char

I have the following string: 

Dim Str As String = "XYZ"

My goal is to achieve every possible string that include dots. It should take care of:
1. Dot should be between Chars
2. The char order cant be change, its just need to insert some dot between chars.

For example:

X.YZ
XY.Z
X.Y.Z

Where should I start?

This might help you get started:

Imagine that a dot = 1 and no dot = 0. For example U.VX.YZ = U1V0X1Y0Z Now remove all the letters and you get some binary : 1010 This suggests you can go from 0000 to 1111 in dots (This is hard to explain) Try doing this process in reverse to get all answers.

For example:

String = "XYZ"
00 = XYZ
01 = XY.Z
10 = X.YZ
11 = X.Y.Z
