Solution 1

Read a chunk of the text file, for instance a line, into a String object and then use the String.IndexOf method.

Use this code to find specific word in text file

VB

Dim InputStr As String = TextBox1.Text

        For Each FileStr As String In IO.Directory.GetFiles("C:\your folder", "*.txt")

            If IO.File.ReadAllText(FileStr).IndexOf(InputStr) >= 0 Then

                ListBox1.Items.Add(IO.Path.GetFileName(FileStr))

            End If

        Next

Thanks
