Writing An XML Document That Has Computer Paths And Special Chars?

Cannot Read Special Characters With Streamreader / Streamwriter
Nov 23, 2009To automate mailmerge function in word, i need to join different elements to complete the mailmergedatasource. In one of these file are words with special characters like ©, §,¨, .... When openng these files for reading, streamreader transfoms the characters to unreadable signs. When i give a type to use to open like ASCII, Unicode,it works for one or tho characters but not for all. I have the same problem when the character is read correctly, with streamwriter output to a textfile. Word cannot read the textfile and ask to define which type of coding should be used. In most of the cases not all the characters can be converted to readable characters.

I have a list(of char) to separate the individual letters in the message (letterList), and textToConvert is the text that the user types in to be encoded. Here's the section of code my problem exists in:

Jul 2, 2010I'm having an issue with the streamreader. I had it working but I've changed something and it has stopped.
I have it in a Do While loop reading line by line, but it doesn't finish reading. It reads about 27 lines out of 4000, then stops.
I changed the contents of the file it was reading, but it's still just save as a txt notepad file.
I also changed how I tell it which file to open (UserSelection.T2) however it does open the file just doesn't finish reading it.
Doesn't kick back any errors, it just doesn't read the entire file.

.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?
Oct 8, 2011In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

Streamreader Limits - The Streamreader Works Fine Until The File Is More Than 100,000 Bytes Long?

The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?

StreamReader/Writer - Loads An Entire Text File Into A Streamreader Variable
Jul 9, 2009I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.
