Hi,

Could some one help me in coding here. I am not very good at these stuff. So anyone could help.
I tried, but I am getting either a wrong value or a zero.

strData = "Location1|22.2|Location2|22.3|Location3|22.4|Location4|22.5"

'This is a string that I retrieve from a url. The string is always the same except for the values and name of location.
'The separator is always "|" character.
'The "Location1|22.2" is one data. And "Location2|22.3" is the second data. Like that four data.

'What I want to do is, I want to write a function in which when I call to this function and pass the location (1, 2, 3 or 4)
'I want to get the respetive value for that location.

Function Get_Value(Location as Integer)

'I want to know the code here...

End Function

Hi warheat001,

Fairly straightforward if you are using VB6:

Get_Value = Split(MyURLString,"|")((Location * 2) -1)

Is the line of code you need.

Private Function GetLocation(ByVal location As Integer, strdata As String) As String
Dim arr

arr = Split(strdata, "|")

 GetLocation = arr(location + 1)

End Function



As an example:

Dim result

strdata = "Location1|22.2|Location2|22.3|Location3|22.4|Location4|22.5"
result = GetLocation(2, strdata)

result now contains 22.3
