search and count occurances of a word in a textbox string - vb.net

Question

Right now I have two textboxes. One is the input and the other the text string. It functions perfectly. Is there a way to get rid of the input box and have the "searched" word in the code so when I hit a button it gives the result.
Private Function FindWords(ByVal TextSearched As String, ByVal Paragraph As String) As Integer
Dim location As Integer = 0
Dim occurances As Integer = 0
Do
location = TextSearched.IndexOf(Paragraph, location)
If location <> -1 Then
occurances += 1
location += Paragraph.Length
End If
Loop Until location = -1
Return occurances
End Function
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = TextBox2.Text ' display result
Label2.Text = FindWords(TextBox1.Text, TextBox2.Text)
' MsgBox("The word " & TextBox2.Text & " has occured " & FindWords(TextBox1.Text, TextBox2.Text) & " times!!")
End Sub

There are a couple of small problems that you'll might see of you turn on option strict in your project's compile settings. Your function returns an integer. To properly assign it to a textbox label, you should really add .ToString to the end of the assignment like this
Label2.Text = FindWords(TextBox1.Text, TextBox2.Text).ToString
So leaving you code as you wrote it, in this sub, you just want to pass a string as the parameter for the text to find?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = TextBox2.Text ' display result
Label2.Text = FindWords(TextBox1.Text, TextBox2.Text)
' MsgBox("The word " & TextBox2.Text & " has occured " & FindWords(TextBox1.Text, TextBox2.Text) & " times!!")
End Sub
Just change it to this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
dim searchString as string="Hello" 'or whatever string you want to use
Label1.Text = TextBox2.Text ' display result
Label2.Text = FindWords(searchString, TextBox2.Text)
' MsgBox("The word " & TextBox2.Text & " has occured " & FindWords(TextBox1.Text, TextBox2.Text) & " times!!")
End Sub
but it might be better to change it a bit more so that your function only gets executed once if you want to display a messagebox with the number of occurences - like this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
dim searchCount as Integer
dim searchString as string="Hello" 'or whatever string you want to use
Label1.Text = TextBox2.Text ' display result
searchCount = FindWords(searchString, TextBox2.Text)
Label2.Text = searchcount.ToString
' MsgBox("The word " & TextBox2.Text & " has occured " & searchcount.Tostring & " times!!")
End Sub
