[Resolved][2008]Find String In String IndexOf("flowers")

[goldenix]

Hi
The problem is that the code cant find word flowers from *.txt file. I added msgbox & looped all 5 lines & I see that the flowers are there. if i change flowers to BIOS, then the code will find the word. So im little lost hire, Why it cant find flowers?

       Dim myOpenFileDialog As New OpenFileDialog()
        myOpenFileDialog.CheckFileExists = True
        myOpenFileDialog.DefaultExt = "txt"
        myOpenFileDialog.InitialDirectory = "C:\"
        myOpenFileDialog.Multiselect = False
        If myOpenFileDialog.ShowDialog = DialogResult.OK Then

            Dim a() As String = Split(My.Computer.FileSystem.ReadAllText(myOpenFileDialog.FileName), Environment.NewLine)
            Dim r As Integer
            Dim i As Integer
            For i = 0 To a.GetUpperBound(0)

                r = a(i).IndexOf("flowers")
                If r > 0 Then ' if found flowers
                    MsgBox("Found word,:" & a(i))
                    Exit For
                End If
            Next            
        End If

*txt file contents:

[BIOS]
Ver=AB60S00P
[BIOS]
Ver=AB60S00P
flowers

this statement If r > 0 Then is your problem.

What does IndexOf return?

aa now I get it. From the example Discription i took it from, the IndexOf should return 0 if no match. But in reality it returns Negative nr if no match.

Thank you. It seems to be working now, just changed if r > 0 to If r >= 0
