Question String Counting

[TommyEvans]

Alright. I have a project I need to complete by 11:00 am today. I need a program that will allow a user to input a phrase into a text box. Another text box to input a letter. Then I need the program to count how many times, the letter appears in the phrase. I have everything set up. I know how to count how many characters are in the string, but not how many designated letters there is. Anyone have any idea?

You can use LINQs Count method.

        Dim inputString As String = "Peter Piper picked a peck of pickled peppers"
        Dim searchChar As Char = "p"c
        Dim result = inputString.ToLower.Count(Function(ch) ch = searchChar)

complete by 11:00 am today ..... Anyone have any idea?

Yes, but it's already 3.30pm so it's too late.

I'm Eastern Time. 10:44am. Matt, how would I go about using text boxes with that?

 

[MattP]

Just take the entries from the textboxes rather than hard coding them in.

        Dim inputString As String = txtInputPhrase.Text.ToLower
        Dim searchChar As Char = CChar(txtSearchChar.Text.ToLower)
        Dim result = inputString.ToLower.Count(Function(ch) ch = searchChar)

Wasn't on time, but it didn't kill my grade to bad. 90/100 is acceptable.

Thanks guys!
