extract a substring from string

[charvi]

i have a name as John smith which i enter in textbox now i want to extract John from John Smith how to do
Thanx in advance

Well it depends whether you know what,where and how long the string is that you want to extract. If you do then i would use Mid(), ie the string "John Smith" = 10 characters. So (Where ever extracted to) = Mid((string or "John Smith"), (1 as "John" starts at position 1), (4 as the length of John = 4). So ... = Mid(string,1,4).


Alternativly if you had a load of strings and you needed to get the first name from all of them you could use:

data = currentname
x=1

Do
If Mid(data, X, 1) = " " Then
' end of first name
Else
' include current symbol with retrieved first name
data2 = data2 & Mid(data, X, 1)
X = X + 1
End If
Loop Until Mid(data, X, 1) = " "
'retrieved data = data2

I think split() is a good choice for this

Yes, you can build the logic to do pretty much whatever you want along these lines, using loops, Mid() function, and depending on your VB version, also Left() and Right() functions. But if the situation is suited to it, the Split() function will be much quicker and simpler.
