Strings is just another word for text and in order to write strings you need to use the " quotation signs. This part will go through some practical ways to work with substrings. A great syntax here is Instr that searches left to right and InstrRev that searches in reverse (right to left) in vba.
We will starting working with the classic analyst phrase. "Please Fix Thx." and modify that one throughout the examples on the page. Let's start with adding the text parts in to three strings.
A = "Please" B = "Fix" C = "Thx."
Now Let's add them all into one string D for further modifications.
'Let's make sure these are added into one string D.
D = A & " " & B & " " & C
Instr Syntax
Instr function similar to the "find" syntax where you want to find a substring in a string. Instr is a case sensitive function and it returns the starting position for a substring.
The syntax functions are the following:
InStr([ start ], string1, string2, [ compare ])
'Fi from 'Fix' is being found at startingposition 8.
MsgBox (InStr(D, "Fi"))
'Asking my code to start looking from Characterposition 10 in "Please Fix Thx."
'This is returning 0 as the substring "Fi" is not found after starting position 8.
MsgBox (InStr(10, D, "Fi"))
InstrRev Syntax
InstrRev is great for when you need to search your word from right to left. Reverse searching with InstrRev function
The syntax functions are the following:
InstrRev(stringcheck, stringmatch, [ start, [ compare ]])
MsgBox (InStrRev(D, "T")) 'returns position 12.
