Hi sir, I'm newbie here. I just want your help.
Let's say, I have these code in my vb:

dim msg1, msg2 as string
msg1=textbox1.text
'notes that textbox1 will be inputed with random string but will contain myname: blablabla
'example
textbox1.text="newejjdhajdahksjmyname: blablabla asljdsjdksk"
'or may be inputed like this:
textbox1.text="asfdssadadamyname: blablabla asadsdasghfhgfhfghfgfhgfgfga"
msg2 = msg1.find(......i don't know how to coding it)
textbox2.text="your name: " + msg2

sorry if I type incorrect english. thanks.

Take a look at this

        Dim smplText As String = "asfdssadadamyname: blablabla asadsdasghfhgfhfghfgfhgfgfga"
        Dim strToFind As String = "blablabla"
        Dim idx As Integer = smplText.IndexOf(strToFind)
        If idx >= 0 Then
            'string found
        Else
            'not found
        End If
