I'm making a calculator that would read a "string" from a textbox and parse it and follow Order-of-Operations/PEMDAS on the string. I have a couple of questions:
1) What would be the best way to parse the code so that it won't just take a "left expression" and "expression" and perform the operation on those 2.
2)How would I be able to make is so that 0 is considered valid, but prevent a 00 or 020 or 002 to be inputed.
The object of this project is to create code for a 4 function calculator that takes a character string like: 5 + 123 + 6 = and generates a new string: 134 There are multiple tasks to be done. First the string must be broken into tokens; in this case, there are 6 tokens:
5, +, 123, +, 6, and =
Dim input As String = (txtIn.Text)
Dim x() As String = input ?????

It's just a small calculator project so it's no big deal, but after I had built the project, I wanted to change the project name and all the file names that had that string in it (and all internal references to that string). I had played with this before and knew that it was asking for trouble but I thought, "What the hell, I'll try it again." feeling a bit brash.
Well, everything works fine in debug mode, but there is this DOS window that pops up just before the main form does, and it doesn't go away for the entire debugging session. I think I see that window pop up on all other projects too (if the main form doesn't cover it up completely), but normally, it's only there for a split second.

This should be simple but apparently it's not. I have a text file, 694 bytes. At byte 500 there's a null in the file. I've tried reading it as text and binary and I end up with a string, 694 bytes long. But anyting I do with this string fails because it appears to stop at character 500. I can do a ? asc(mystring.substring(549,1)) and I get 9 (tab). Print character 550 and I get 0. Print character 551 and I get 32 (space). How do I get rid of this null?
