I tried what you wrote and for some reason it isnt liking this line of code :
Dim MC As MdiClient = clsGetMDI.GetMdiClient()
I get a squiggly under clsGetMDI.GetMdiClient. I changed the name of the class by the way from toolbox to clsGetMDI. It is saying argument not specifyed for the parameter frmMainMDI in the public function getmdiclient etc. frmMainMDI is the name of my MDI Parent form. I have the exact same code you do except I replaced MDIForm with the name of my actual MDI form and I have a different class name where the function is located, that is it. Other than that I am using the exact same code.
Any thoughts????

You need to pass in the the form. Sorry about that.

DataGridViewTextBoxCell has a single constructor, which takes no parameters. I would like to extend it to have a constructor with an object parameter, which will set its value in one statement, like this:
DGVRow.Cells.Add(New DataGridViewTextBoxCell(StartingValue)) The extension method should look like this:
Public Module Extensions
<Extension()> _
Public Sub New(ByVal this As DataGridViewTextBoxCell, ByVal Value As Object)
this.Value = Value
End Sub
End ModuleThis produces error squiggles under Public ("Shared 'Sub New' cannot be declared 'Public'") and New ("Shared 'Sub New' cannot have any parameters.") Using any name other than New eliminates the errors.
Can what I want to do be done without subclassing?

You would have to create a class derived from the DataGridViewTextBoxCell and then add a constructor that would call its base constructor.
Also, since the new constructor is used on a per instance basis you cannot use the shared keyword.

I'm guessing that the Shared keyword is added implicitly, by virtue of it being in a module. Ah, well.

Yes, everything in a module is static.
Despite everything, the person most likely to be fooling you next is yourself.

I suggest taking on simpler tasks until you are up to speed with vb.net....

Yes, just check to see if the client's IP is one that you accept. Refer the second post here[^] on how to get the client's IP.

I am using following API function to open folder browse window. I want to show only selected drives not all the drives. Can anyone help me to achieve this task as I am not a .net programmer.
Thanks
Public Function BrowseForFolder(ByVal sTitle As String, ByVal sRootPath As String) As String
Const WINDOW_HANDLE As Long = 0
Const NO_OPTIONS As Long = 0
Const BIF_NEWDIALOGSTYLE As Long = 64
Const BIF_EDITBOX As Long = 16
Dim fctResult As String
Dim objShell As New Shell32.Shell()
Dim objFolder As Shell32.Folder
Dim objFolder2 As Shell32.Folder2
Dim objFolderItem As Shell32.FolderItem
fctResult = ""
objFolder = objShell.BrowseForFolder(WINDOW_HANDLE, sTitle, NO_OPTIONS Or BIF_NEWDIALOGSTYLE, sRootPath)
If Not objFolder Is Nothing Then
objFolder2 = CType(objFolder, Shell32.Folder2)
objFolderItem = objFolder2.Self
fctResult = objFolderItem.Path
End If
objFolderItem = Nothing
objFolder2 = Nothing
objFolder = Nothing
objShell = Nothing
Return fctResult
End Function

I'm not quite sure what you mean by "show only selected drives not all the drives", but you may want to start by changing to .Net's FolderBrowserDialog[^] component. With the FolderBrowserDialog you won't have to fool with the APIs.
If you are wanting to restrict what drives they can choose, you could either show a MsgBox if they pick a disallowed drive and ask that they choose again, or check out the Folder Browser component for .NET[^] article. You can probably edit it to not display drives that you want to be hidden.

Many thanks for your reply. I mean I don't want user to save documents in C or D drive but they are allowed to save on network drives.
