Searching Registry And Removing Keys For MS Loop Back Adapter?
Aug 15, 2010
I am trying to creat a program to automate many of the things I do when I build a computer. I was attempting to do this via batch files but got stuck when I needed to search the registry for cetain keys and delete the parrent folder in which it resides in.
For instance: Installing a MS Loop Back Adapter I found a utility that works at the command promt called DEVCON that will allow me to install a MS Loop Back Adapter. I was doing this through a batch file but found that I can call the utility through VB and get the same result (of course I still need to have the DEVCON.exe)

I am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?
I am using VB.net 2008 and Windows XP.

How could I loop through a list of the keys that are available in the 'Keys' enumeration? It seems like it should be something easy to do, but I'm not having any luck finding a collection that I can loop through.

Because I'm handling my keydown on the form that basically complicate obvious thing. Now I have to manually program my keys.back on a richtextbox. However, the code below put my cursor back to the beginning of the textbox everytime I delete a char. Is there a way I can control my cursor to stay where it is?
Private Sub Form_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyValue = Keys.F1 Or Keys.F2 Or Keys.F3 Or Keys.F4 Or Keys.Escape Then
'call my other functions

I have this code to delete a registry key:
Private Sub RemoveCurrentKey(ByVal name As String)
Dim key As RegistryKey = Registry.CurrentUser.OpenSubKey("Software\", True)
key.DeleteSubKeyTree(name)
End Sub
But it simply wont remove the key tree, How do I remove the whole tree?

I want to get all sub keys in a reg location. This entry can also have additional sub keys.At location "HKEY_CLASSES_ROOTexefile" this key as 3 subkeys and 2 of these keys have additional sub keys under them. I need to get all the keys and any additional sub keys under each key if there is any. This code will be used for other keys, so I can not assume they have subkeys.
Dim Key As RegistryKey = Registry.ClassesRoot.OpenSubKey("exefile", False)
Dim SubKeyNames() As String = Key.GetSubKeyNames()
Dim Index As Integer

I'm trying to:
Check for any unused data in the registry relating to MS Loop Back Adapters and remove it
Install New MS Loop Back Adapter
Remove some of its bindings
Remove the Show Icon
Adjust the order of the network adapters
The issue I am having is finding a way to search all sub folders with in a certain folder in the registry. This is the code I have so far
Dim x As Integer
Dim NetworkAdapterLoc As String = "SYSTEMCurrentControlSetControlNetwork{4D36E972-E325-11CE-BFC1-08002BE10318}"
'{1535ADE9-7E74-4508-951F-30F23A29B5A4}" - This is on of the subfolders I want to look in on my machine
Dim RegKey As Microsoft.Win32.RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey(NetworkAdapterLoc)
[Code] .....
I even tried to replace the
MSLoopLocKey = RegKey.OpenSubKey(subname(x))
with this
MSLoopLocKey = RegKey.OpenSubKey(NetworkAdapterLoc & "" & subname(x))
But in either case I just seem to list the sub folders I actually want to be searching. A lot of the tasks I want to accomplish with my application will require me to search through multiple sub folders in the registry and either modify the data in a key or remove the entire folder.

i have a very short program that is basically mimicking the back, playpause and next functions for music (because my keyboard does not have buttons along top ), so i am using numpad. now, of-course, by using numpad, it's typing the number 2, so if i am running an application with a textbox it will type the number 2, so i want to delete this, but i do not know how.

I'm trying to access a registry key that has a space in it, specifically:
SoftwareMicrosoftWindowsCurrentVersionWindowsU pdateAuto Update The key is valid and I believe the code is, though I can't get any keys with spaces to open using Registry.OpenSubKey
The following code fails only for keys with spaces: subkey = New String("SoftwareMicrosoftWindowsCurrentVersion WindowsUpdateAuto Update")
m_hive = m_hive.OpenSubKey(subkey, False) Dim val As Object = m_hive.GetValue(key)

I have an application where i need to enumerate the random subkeys under another registry key and then create a new registry value. The problem is I cannot figure out how to enumerate those values and then write my new values The key specifically is SystemCurrentControlSetServicesTcpipParametersInterfaces{NIC-id}where NIC-id is a subkey with random letters and numbers. However the caveat is if I can only write values under the NIC-id's that have IP addresses... if not that is fine too but I would prefer to only write the valus below under NIC cards that have IP addresses

Trying to read a registry key that has a name and a value associated with it. However, the value name doesn't have a name, per say, but it does have a name of (Default).
Anyway, the following lines of code return a value of Nothing.
Dim ReadValue As Object = My.Computer.Registry.GetValue _
("RegKeyName", "(Default)", Nothing)
'Try to use "(Default)" for the name.
However, if I pass empty quotes, as the ValueName, it returns the correct value for the value name. I spent quite alot of time before even thinking of trying it with empty quotes.
Dim ReadValue As Object = My.Computer.Registry.GetValue _
("RegKeyName", "", Nothing)
'Passing empty quotes for the name.
Is passing the empty quotes the correct way of getting the values from the (Default) value names? I don't want to assume this is going to work in all occasions only to get tripped up later.

I am working on a program that needs to fetch remote windows pc's particular registry keys and then be able to modify them (for example the Run registry key). From what I have been reading I would need to use the OpenRemoteBaseKey to do so.
What I am not sure about is how do I have the program search the network for all of the Windows computers and generate a checklist when the computer names and IP addresses are not known ?
also for the OpenRemoteBaseKey to work do I have to know the password for the administrator account for each PC ?

I need to get a list of registry keys. I have a key in HKEY_LOCAL_MACHINESOFTWARECBV
In there I have a couple of more keys that I need to list. After that I'll be able to get the subkeys easily.
I've looked and the only call that seems to do this is RegOpenKeyEx. Is there a better or more up to date method that I can use?
I've looked at My.Computer.Registry.LocalMachine and can only see methods to get the subkeys and not keys.

I have run into a brick wall here with trying to figure this out what I have is a button that when clicked on opens up the windows control panel. and then options can be set and you then close the control panel.
then there is two radio buttons one says enabled and one says disabled what they do is check the registry after the button has been clicked on and depending on if the registry is set for 0 or 2 0 for disabled 2 for enabled...
I've tried various ways but I cannot get the radio buttons to check properly

I am wondering if there is a way to get the keys from the registry and display them in a checked listbox. For example I want to get all the keys and there values from "HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun". This will allow me to see all the startup items. Is there a way that I can get all the values and display them in a checked listbox. I tried using the GetValue but it seems that you have to set the key that you want.

I have problems about USB device drivers: I can see the driver correctly installed but application says device is not present.
I solved using Regedit:
in
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSB
I have to manually delete the key
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSBVid_04d8&Pid_8001
with all subkeys.
I've seen there are several examples managing registry keys using vb, but I can't understand how detect if the key is present and how delete it.

I have a program which will search the entire registry for a keyword and display all the matching keys/values in a listview. The user can then select the desired keys/values and delete them. Since this a program that deals with registry, I want to give the users a way to backup the registry before they do the delete operation. I would like to know what is the best approach for this.
3 questions here:
1- Should I backup the entire registry ?
2- Should I backup only the keys/values that the user has selected in the listview ?
3 - Can I have the sample code or appropriate URL's which describes this.

I have setup my listview to View: Details
I want the listview to show all the keys of a specific folder.
Example: HKEY_CURRENT_USER\Software\Microsoft\VBExpress\10.0
So you click button1 and it adds all the keys within the example to your listview.
