View 4 RepliesI'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...
When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?

In 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]"

One problem is what I want to achieve:
I want to have:
$123.00
$15.00
$1,000.00

so I have"

I know that MD5 is a 1 way(Meaning that there is no decryption for it, yet)
now I was wondering if SHA-1 is a two way. Also, is there any other hashing method that are 2way?
reason is that I want to convert a long string (Lets say 550 chars) into something lower (From 550chars to something lower then 550chars)
I can use a Key, but every possibility will give me bigger length then the actual string.
