[RESOLVED] generate links from text

i was wondering the best way to generate a link from plain text, in other words 'link-a-fy' text.

for example, the text says

Code:

---


http://vbforum.com

---

but i want that converted to :

Code:

---


<a href="http://vbforum.com">http://vbforum.com</a>

---

the number of links in the text file (or string) will vary.

so let's say i have this text file:

Code:

---


The little red fox can be found at http://redfox.com and the little red hen can be found at http://littleredhen.com

you can also get the red puppy at:

http://redpuppies.net

if you have any more questions send them to:

would read like this when revised:

Code:

---


The little red fox can be found at <a href="http://redfox.com">http://redfox.com</a> and the little red hen can be found at <a href="http://littleredhen.com">http://littleredhen.com</a>


you can also get the red puppy at:

<a href="http://redpuppies.net">http://redpuppies.net</a>

if you have any more questions send them to:

i know this sort of trick is as old as the hills, but it is new to me. hopefully it isnt too hard to do

Code:

'API Guide
Private Const S_FALSE = &H1
Private Const S_OK = &H0
'Only implemented as unicode...
Private Declare Function IsValidURL Lib "URLMON.DLL" (ByVal pbc As Long, ByVal szURL As String, ByVal dwReserved As Long) As Long
Public Function IsGoodURL(ByVal sURL As String) As Boolean
    'KPD-Team 2001
    'URL: http://www.allapi.net/
    'E-Mail: [email protected]
   
    'The IsValidURL always expects a UNICODE string, but whenever
    'VB calls an API function, it converts the strings to ANSI strings.
    'That's why we're going to use a trick here. Before calling the function,
    'We're going to convert the unicode string to unicode so we get a double
    'unicode string.
    'Before VB calls the API function, it converts our double unicode string
    'to a normal unicode string; exactely what IsValidURL is expecting.
    sURL = StrConv(sURL, vbUnicode)
    'Now call the function
    IsGoodURL = (IsValidURL(ByVal 0&, sURL, 0) = S_OK)
End Function

'My code
Private Sub Command1_Click()
Dim Prts() As String
Dim Lns() As String

    'split the text into lines
    Lns() = Split(Text1.Text, vbNewLine)
    'Go through each line
    For l = 0 To UBound(Lns)
        'Split each line into words
        Prts() = Split(Lns(l), " ")
        'go through each word
        For p = 0 To UBound(Prts)
            'if a word is a url (urls don't have spaces ;)), then we fix it up
            If IsGoodURL(Prts(p)) Then
                'Fix it
                Text1.Text = Replace(Text1.Text, Prts(p), "<a href=" & Chr(34) & Prts(p) & Chr(34) & ">" & Prts(p) & "</a>")
            End If
        Next
    Next
End Sub

A bit of code from API Guide as well :)

perfect. very much appreciated
