Use following I use this in my project also. It will solve your problem just copy past this code in VB and as code design your GUI.

Private Sub Getmem_Click()
Dim varone As String
Open " enter your text file path " For Input As #1
Input #1, varone
Text1.Text = varone
Close #1
End Sub

To write to a file, try this:
Private Sub writefile_Click()
Dim strmsg As String
Dim Sname As String
Open " enter your text file path " For Output As #1
strmsg = MsgBox("File sample.txt opened")
Sname = InputBox("Enter Name")
Print #1, Sname
strmsg = MsgBox("Writing a" & Sname & " to sample.txt ")
Close #1
strmsg = MsgBox("File sample.txt closed")
End Sub

Hey I give you short but sweet code to use it and enjoy your project, it will help you to reduce the compile time and also reduce the code of line, every time write short but useful code it will help you to decreasing the compile time of your application.

Close #1

Here Open statement gives you to opening access and writing access to any of the file, here you can specify if you want to read it as text, write to it as binary, and so on. In this code you can set locking options, to stop other programs from opening the file.
Use this code it work fine, without any modification

Dim filnam as String
Dim fileno as Integer
fileno = FreeFile
Open "C:\Test.txt" For Input As #fileno
Do While Not EOF(fileno)
Input #fileno, filnam
MsgBox filnam
Loop
Close #fileno

Reading/writing files can also be acheived using FILSYSO (FileSystemObject) as shown below. Please note that using FILSYSO requires an extra reference (under "Project"->"References"), and therefore extra files to be installed with your application.

Option Explicit
Dim filsys As FileSystemObject
Dim txtstrm As Textxtstrmtream
Set filsys = New FileSystemObject
Set txtstrm = filsys.OpenTextFile("C:\test.txt", ForWriting, True)
txtstrm.WriteLine "This is"
txtstrm.WriteLine "VB Form"
txtstrm.Close
If filsys.FileExistxtstrm("C:\test.txt") Then
Set txtstrm = filsys.OpenTextFile("C:\test.txt")
Do While Not txtstrm.AtEndOfilsystream
MsgBox txtstrm.ReadLine
Loop
txtstrm.Close
End If
Set txtstrm = Nothing
Set filsys = Nothing
End Sub
