File I/O And Registry :: Reading Multiple Keys From The Registry?

Aug 27, 2008

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.

Reading Registry Keys With Name Of (Default)

Mar 5, 2006

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.

VS 2010 Reading Remote Registry With WMI Returns No Results

Feb 9, 2012

I am trying to read the HKEY_USERS hive of a remote machine with this Class

Imports System.Management
Imports System.Management.Instrumentation
Public Enum RegHive As UInteger

[Code]....

The value of sSubKeyName is the user's SID + "" + Network (e.g. S-1-5-21-1606980848-2025429265-839522115-560021Network). Now under that key are various subkeys containing mapped drive letters. But it never returns anything.

Strangely, if I use the OpenRemoteBaseKey method it works BUT I don't want to use that because using WMI lets me specify alternate credentials and OpenRemoteBaseKey doesn't

Get Registry Subkeys And Create New Keys?

Oct 19, 2009

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

Remote Windows Registry Keys?

Dec 28, 2009

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 ?

Alternative To RegOpenKeyEx To Get List Of Registry Keys

Jun 23, 2009

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.

I've tried various ways but I cannot get the radio buttons to check properly

Backup Registry - Keys / Values Displayed In ListView?

Nov 22, 2009

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.

Shortcut Keys Not Working?

Feb 16, 2010

I have an application which I am trying to implement shortcut keys in. The application contains a main window from which dialog popups can be opened. I am having difficulty implementing the shortcut key functionality on the popup windows. I have the following code in one of the popup windows, and even though the first three key entries are the exact same as on the main window (except for the actual button names), which works, the same code does not work on the popup.

Private Sub frmInduction_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.Control + Keys.S Or e.KeyCode = Keys.F5 Then
btnAccept.PerformClick()

[code]....

I am opening the popup window with the following code- is there any way that the problem could be caused by how I am opening the popup?

Using frm As frmChangeValue = New frmChangeValue
frm.ShowDialog()
