Open a txt file when a button clicked in VB.NET

vb.netvb.net-2010

提问by User7291

I have a log file in my project. This file is a text file (.txt). Is there a way to open this file when a button clicked without using the OpenFileDialogtool?

Dim FILE_NAME As String = "C:\FileName.txt"

If System.IO.File.Exists(FILE_NAME) = True Then
    Process.Start(FILE_NAME)
Else
    MsgBox("File Does Not Exist")
End If

Here is a simple example:

这是一个简单的例子:

 Public Class OpenTextFile

    Private Sub OpenTextFile_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub

    Private Sub OpenBUT_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenBUT.Click
        'OpenBUT_Click the text file
        Process.Start("C:\File Name.txt")
    End Sub
End Class
