1.
for i=1 to len(string)
c=mid(string,i,1)
next

2. cred ca exista si o varianta mai simpla, nu stiu
Dim v As String, str As String
v = "var"
str="varza"
For i = 1 To Len(str) - Len(v) + 1
If Mid(str, i, Len(v)) = v Then MsgBox v & " se afla in sirul " & str & " cu incepere din pozitia" & i
Next

atentie: sa folosesti UCase sau LCase daca e cazu`; ca se fac diferente intre literele mari si mici.

Daca la Visual Basic.NET te referi, gasesti tot ce tine de string-uri la:

Daca inca mai folosesti VB 6, niste chestii interesante despre strings in VB6 se gasesc la:
