ok so the title isn't very clear but here is what i need to do(i have searched im not sure if i searched right because i don't really know what to type but) i want it so if there is a / in a label it will turn the / into a - thanks in advance even if u can't help me.

Code:

Label1.Text = Label1.Text.Replace("/","-")

If you need to replace multiple items, then use the following format:

Code:

Label1.Text = Label1.Text.Replace("A",a").Replace("B","b").Replace("C","c")

...

[php]
For each m as match in Regex.Matches(Label1.Text, "[ABC]")
Label1.Text = Label1.Text.Replace(m.value, m.value.tolower)
next
[/php]

No shit lol, I just like Regex and giving Hassan shit 'cos he forgot a lot of it

Although I do like this function, very VERY occasionally comes in handy :P

[php]
Private Function ReplaceText(ByVal original As String, ByVal replaceWhat() As String, ByVal replaceWith() As String, ByVal ignorecase As Boolean) As String
If replaceWhat.Count = replaceWith.Count Then
For i As Integer = 0 To replaceWhat.Count - 1
If ignorecase Then
original = original.ToLower.Replace(replaceWhat(i).ToLower, replaceWith(i).ToLower)
Else
original = original.Replace(replaceWhat(i), replaceWith(i))
End If
Next
Else
MsgBox("arrays not the same size")
End If
Return original
End Function

'...
textBox1.Text = ReplaceText(TextBox1.Text, New String() {"A", "B", "C", "D"}, New String() {"x", "y", "z", "w"}, false)
[/php]

(Yes i'm procrastinating from study)

I've never seen this before "ByVal replaceWhat() As String"... Why () after the variable name? ._.

Also err, RegEx comes in handy when filtering emails, BBCode creation and filtering user input like birthdays.

() denotes an array, so the function requires you to pass 2 string arrays into it. (thought you would know something basic like this)

i.e
things to replace{"hello", "this", "is", "a", "test""}
replace with (same order as first array) {"i", "höpe", "this", "works", "good"}

hello will be replaced with "i"
"this" will be replaced with "hope"
"is" will be repaced with "This"
...etc

Easy way of replacing multiple things.

As a sidenote, regex is useful for a lot more than filtering emails etc...there are many many cases where it can be extremely useful.

Oh woops --"

Looked like a function to me ~.~

Even in Visual Basic, I use [] to denote an array. It so much easier than distinguishing between a function with a paramter or an array when you're using a complex, long line of code.

Don't mess with me kid.

@freedompeace: Lol what ? You really used '[]' in Visual Basic to donate an array or you trolling me ? LOL

I'm better than you at VB, remember?

.

@freedom, () does't really look like a function at all, I have no problems reading a long line of code where () is used to denote an array, but maybe that's just me.
