i am not sure what you are looking for but you can use the OpenFileDialog found in VB.NET if this is not good for you and you want to implement something like windows explorer you have to write your own code to browse files and folders and add them to the tree view. hope this helps you

Thank You Sir I need to know how to implement something like windows explorer (My problems looks like when we open My Computer and then click on the icon Folders we see tree on the left of the screen and on the right we see all files and folder in specific directory I need to implement this) I look forward to hear from you soon

Dim Files() As String = System.IO.Directory.GetFiles("c:\") Dim Folders() As String = System.IO.Directory.GetDirectories("C:\") For Each F As String In Folders If (System.IO.File.GetAttributes(F) And IO.FileAttributes.Hidden) <> IO.FileAttributes.Hidden Then Me.TreeView1.Nodes.Add(F, F.Split("\")(F.Split("\").Length - 1)) End If Next For Each F As String In Files If (System.IO.File.GetAttributes(F) And IO.FileAttributes.Hidden) <> IO.FileAttributes.Hidden Then Me.TreeView1.Nodes.Add(F, F.Split("\")(F.Split("\").Length - 1)) End If Nextyou can use something simillar to this code. this code only adds files and folders under the c:\ directory. you can extend this code to add other files under each folder. the best way is to make the function a recursive function but this will make your program very very slow. what i suggest is call this function everytime a node is clicked this add the childern of that node using this function. the nodes.add function can be extended to include icons to differ between a file and a folder. to add a child node you can use the following line:me.TreeView1.Nodes.Item(me.TreeView1.Nodes.IndexOfKey(Key)).Nodes.Add()where the key is what i specified in the first argument of the Nodes.add line (= F) hope this helps, if you need further help please let me know Khalid -

Dim aDriveAs String For Each aDrive In Directory.GetDirectories("E:\") If (File.GetAttributes(aDrive) And IO.FileAttributes.Hidden) <> IO.FileAttributes.Hidden Then T.Nodes(0).Nodes.Add(aDrive) End If NextBut I need the following When I select folder from tree I want to display All files and Folders on a panel or somthing like this,i.e. in the same way as (windows explorer) so I can Open,Copy or delete any file or folder Thank you again -

What i suggest is use the same code as mine (add only the name of the file and use the Name property of the node to store the whole path. if you do this, then you would have to use the line: MsgBox(e.Node.Name) instead of the first one. after you get the path of the selected node, then you can use a list view control to display files and folders and do whatever you want to do with them. hope this makes things more clear.

to add items you just need to call ListView1.Items.Add("aa" ,0) to add an item called "aa" with icon index of 0 the index of the icons is found from an ImageList control that you have to add and insert images into. after adding the ImageList, you have to specify the Me.ListView1.LargeImageList = Me.ImageList1 to define the large images of the items and then change the image size in the ImageList to 32,32. by default, the ListView control displays LargeIcons (after setting up the steps before) but just in case you have to specify the propoprty ListView1.View = View.LargeIcon hope this helps you..
