VB.Net Solution - On Screen Keyboard

Attached is my VB.net solution for your review.

The test file (sample.txt) needs to be copied to the root of your c: drive.  I could have added a dialog box but wasn't sure how far you wanted me to go and kept it basic.

Also, the documented output in the readme.md states an example of:
"D,R,R,#,D,D,L,#,S,U,U,U,R,#,D,D,R,R,R,#L,L,L#,D,R,R,#,U,U,U,L#" (#1)
which I believe is missing some commas and should be: 
"D,R,R,#,D,D,L,#,S,U,U,U,R,#,D,D,R,R,R,#,L,L,L,#,D,R,R,#,U,U,U,L,#" (#2) 
Assuming I'm correct my output shows the same as #2 above.

txtOutputResults textbox on screen only shows last line read (not the cumulative results if there were multiple lines read from the text file).
