| Well the topic title pretty much explains it all. Is there any possible way to write parenthesis to a text file in visual basic? I tried looking up it's character decimal but it doesn't have one. Anyone have an idea on how to do this? |

Open "file.txt" For Output As #1
Print #1, "()"
Close #1 |

| Whoops I don't know what I was thinking. I actually needed quotation marks, not parenthesis. Sorry. That's whats more difficult. |

You do two quotes to represent one, so to put a single quote in a file:
Code:
Open "file.txt" For Output As #1
Print #1, """"
Close #1
To put "This is in quotes" in a file:
Code:
Open "file.txt" For Output As #1
Print #1, """This is in quotes"""
Close #1

| Thanks. I guess it just required more quotation marks than expected. I was only putting two pair and not three. |

Well, keep in mind that if two quotation marks are needed to display one, then at the beginning or end of a literal string you need three, one for the beginning/end of the string, and two for the quotation mark in the string.
Personally, I find this method visually unpleasant. I think you can also use something like chr(34) to get the quotation mark (I'm not sure if chr is the function, but I'm pretty sure 34 is the ascii value...too lazy to check).
I can't think of many reasons to want to write quotation marks to text files...is this perhaps going to be used in a new TI-BASIC editor for the computer?  |

There is no predefined constant for it in http://msdn2.microsoft.com/en-us/library/f63200h0.aspx so you need Chr$(34)
"Visual Basic is visually " & Chr$(34) & "unpleasant" & Chr$(34) & "."
Output text should come from a template or other resource. It should not be hardcoded. Then you don't have this problem.

I assume this is VB6. If it isn't, then forget everything you ever knew about VB6's file manipulation and take a look at the TextWriter class (or the File class with, for example, its static File.WriteAllText method).
(If you are using VB6, I strongly recommend moving to later versions, which make significant improvements to the language).  |

| OK, then I'd take a look at System.IO and the marvels within. |
