Replacing Slashes In a String

[HimeAnator]

I have a text box that the user types in name a file but if the user enters "/" or a "\" the app crashes. So what would be the best way that I can check for them and replace them or block them?

t=t.replace("/","")

not sure how java deals with special chars, might need to escape them like "\/" or "\\"

t=t.replace("/","")

Thank you Sorex that worked perfectly! :sign0060:

Just for the record, as I bumped into the issue today. I needed to replace / by \ to make a path and found this thread.

Escaping did not work, replace never saw "/".

Finally, this worked :

t.Replace(Chr(47), "\")

I know the topic is old, but I post to avoid others to waste time on a non working solution.

This works too:

t.Replace("\/", "\")

"/" is a special character.
"\" is an esacape character
so "\/" looks for "/".

I know what escape characters are. That was the first thing I tried. It simply did nothing here.

This code is identical to:

t.Replace("/", "\")

(You don't need escape the slash).

Test it with:

Dim t As String = "a/b/c"
Log(t.Replace("/", "\"))

Indeed on the surface both the variable and the literal are the same thing.

However, just tested again, literal "/" does not work, whereas chr(47) works.

I suspect they are not parsed the same way.

Can you post an example where it doesn't work?

 

[MitchBu]

OK. Just creating the example, now I see it working. No idea what happened before. Sorry for the trouble.
