Use the DirectoryInfo and FileInfo classes.

That sounds about right. For each directory you then have to loop over the subdirectories, for each of the subdirectories you have to loop over the subdirectories, and so on...

This code is for VB. VB.Net is quite similar though.
Set a reference to Microsoft Scripting Runtime
Dim srt As New Scripting.FileSystemObject
Dim drv As Drive
Dim fld As Folder
Dim f As File
Set drv = srt.Drives("C:\")
Set fld = drv.RootFolder
For Each f In fld.Files
Debug.Print f.Name
Next
If you want to loop through each directory as well you will need to create another function to return the folder object. To check to see if a folder has sub folder use the following code: fld.SubFolders

There are some classes in System.IO that do the same that you are doing. The problem is to loop over all directories with this classes. I will try to do a loop with your code.
Thanks again!!!

Here is something I wrote a few years back in VB6 to simple create a text file of all of my MP3s. It doesn't filter them by *.MP3 since that is all that is in that particular shared drive but you get the idea. I haven't had to mess around with the system.io yet. But the below does work. Give it a try.
Dim fso As New FileSystemObject
Dim List As TextStream
Const C_PLUS As String = "+ "
Dim i As Integer ' Indent
Private Sub Main()
Dim d As Folder
Set d = fso.GetFolder("N:\")
Set List = fso.CreateTextFile(d.Path & "NewSongList.txt", True)
DoFolders d
List.Close
End Sub
Private Sub DoFolders(fldr As Folder)
Dim d As Folder
If i = 0 Then
List.WriteLine Space(i) & C_PLUS & fldr.Path
Else
List.WriteLine Space(i) & C_PLUS & fldr.Name
End If
i = i + 2
DoFiles fldr
For Each d In fldr.SubFolders
DoFolders d
Next
i = i - 2
End Sub
Private Sub DoFiles(fldr As Folder)
Dim f As File
For Each f In fldr.Files
List.WriteLine Space(i + 2) & f.Name
Next
End Sub

Hi,
Yes, the idea is great, I am going to use your example, but I will try to use the system.io class, if I can´t, I will use your example as it is.....
Thanks, it is what I was looking for....

I bit more information on the background would be helpful.
For instance. I don't know if you already have a second thread, or you want to launch a thread to close the form or what?

we run an ERP system at work that is in a client server environment. On the server side there are hundreds of exe files that could be ran from the client machine. I was wanting to write an application that would poll the client machine periodically and somehow monitor if the user has any inactivity by looking at the user proccesor time and kill it if there hasnt been any activity in a pre deteremined time period. This seems to be cumbersome with the amount of exe files i would have to monitor. I did notice that the ERP systems uses some DLL files and wonder if there is a way to monitor them instead for activity? or maybe monitor something on the netowrk that shows data being sent back and forth. Any ideas would be great.

I can use Knowledge base article 243058 to open a office application like Word or Excel but when I try to open PowerPoint it open the presentation of the .ppt file and not powerpoint as the other file types do. Is there another ppt file type that will trip the opening of the product itself with a presentation loaded or at least can I open a power point in the control and then open a ppt presentation?
Is there another way to embed an Office application in a windows form other than using the a Webbrowser control?
Thanks, GregC

Iam developong a tab control on an MDI form. I want to add a tab page with a menue click event, and under certain circumstances, I would like the tab on the new tab page to be a different color (LlightGrey). I have written a sub which I think should work to draw the new color, but I can't seem to trigger the DrawItem Event when the new tab page is drawn, so the routine never runs. does anyone have any suggestions?
Thanks!

From my windows.net application I can shell to an external application and run it using sendKeys.Wait keystrokes. … This all works fine but it does it out in the open.
When I use AppWinStyle.Hide or ApWinStyle.MinimizedFocus or ApWinStyle.MinimizedNoFocus the application appears when the “ENTER” is execute and again when the “F9” is executed Otherwise it is hidden or minimized.
Any Ideas? Thanks GregC
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ProcID = Shell("C:\wincopy\wincopy.exe", AppWinStyle.Hide)
AppActivate(ProcID)
SendKeys.SendWait("{ENTER}")
SendKeys.SendWait("{F9}")
End Sub
Thanks, GregC

:(Hi all who know all
I have a problem in that I need to automate an excel spreadsheet with external data sources and update the data from a remote server. Problem is, this is a standard spreadsheet which I cannot (not allowed) change yet want to read certain data from it once it has updated.
Starting Excel and automating the update is not a problem (see code below). However, I need to know when the update is complete since I then have to extract specific data from this spreadsheet in my code in VB to use. How can I get feedback from Excel to say that the update is complete or alternatively pass execution to another piece of code once the update is done.
"Command1_Click" section of code works fine - its the "AfterRefresh" bit thats got me stumped since it don't work!!!!!!!! The "AfterRefresh" section apparently refers to a PivotTable according to the excel Help section but I am not using a PivotTable.
Any help would be GREATLY appreciated
Regards
Jeremy
Private Sub Command1_Click()
Set m_objExcel = Excel.Workbooks
Dim msExcelWorkbook As String
msExcelWorkbook = App.Path & "\ExcelReports\Update.xls"
m_objExcel.Open msExcelWorkbook
m_objExcel.Application.Visible = True
m_objExcel.Application.ActiveWorkbook.RefreshAll
End Sub
Private Sub ActiveWorkBook_AfterRefresh(Success As Boolean)
If Success = True Then
m_objExcel.Application.ActiveWorkbook.Save
m_objExcel.Application.ActiveWorkbook.Close
m_objExcel.Application.Quit
Call MsgBox("Refreshed all Data", vbOKOnly)
Else
' failed or was cancelled
End If
End Sub
