Insert String

I'm having trouble inserting a string into another string. I need it to find the character "{" then place a set of strings on the next line. I have this (No error, just doesn't work)

vb.net Code:

Dim L As Integer
 
        L = AppM.ToString.IndexOf("{")
 
        Debug.Print(L)
 
        AppM.Insert(L, _
..")
 
        FrmCode.RTB3.Text = AppM

AppM = AppM.Insert(L, _ 'etc
