How to execute two commands sequentially - vb.net

Question

Private Sub btnUnHide_Click(sender As Object, e As EventArgs) Handles btnUnHide.Click
Dim path As String
fdbUnHide.ShowDialog()
path = fdbUnHide.SelectedPath
RunCommandCom(path)
End Sub
Shared Sub RunCommandCom(path As String)
Dim unhide As String = "attrib -r -s -h /s /d"
Try
Shell("cmd.exe /C cd " & path)
Shell("cmd.exe /C" & unhide)
End Sub
I also tried using "&" but didn't work
Shell("cmd.exe /C cd " & path "& " & unhide)
Can anybody help me with this?

Answer 1

NOTE: This answer addresses the problem asked in the question, but it is certainly not the best way of un-hiding a folder and its files.
THE BEST and recommended approach is described in Ctznkane525's answer.
The problem with your current code is that you are missing a space before the ampersand (&).
This:
"cmd.exe /C cd " & path & "& " & unhide
essentially becomes:
"cmd.exe /C cd C:\your\path& attrib -r -s -h /s /d"
...making & part of the path. You need to add a space before it:
"cmd.exe /C cd " & path & " & " & unhide
Though be aware that Shell() is an outdated function from the VB6 era and shouldn't be used. When "executing commads" (or more correctly: starting processes) you should use the Process.Start() method:
Process.Start("cmd.exe", "/C cd " & path & " & " & unhide)

Answer 2

Here is how you unhide a folder in .net and the files
Dim t As New System.IO.FileInfo(path)
t.Attributes = t.Attributes And Not FileAttributes.Hidden
For Each fn As String in Directory.GetFiles(path, "*.*", SearchOption.AllDirectories)
t = New System.IO.FileInfo(fn)
t.Attributes = t.Attributes And Not FileAttributes.Hidden
Next
The attributes are a bitwise flag. You'll want to import system.io at the top.
