Currently, I am try to get the email addresses that have been saved or stored by the user of the computer. This isn't the emails that the user has sent or received, or the contacts he/she has in his address book. Just simply the email accounts that have been accessed from the computer.I know that there are some locations stored in the registry that have the email account. The email addresses that are used on the current computer. I just can't seem to find them on my computer.I am not sure if the registry is the only place to find it or if it stored on the web browser such as internet explorer or google chrome.

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.

I have several programs that must write to HKLM in XP and Windows 7/64 Pro.The programs work in VB6 but not in VB.Net 2008 on target machines. It does works on our development machine. [code]I just cannot figure out why VB6 works but .net doesn't and fails only on the target machine not the development machine.

I just bet the answer to this question already exists, however I saw no search mechanism under the forum. Anyhow, I would like to change registry data, and this code is asking for an instance to the object.
Dim RegKey As RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_CURRENT_USERSoftwa reAnyDWGSoftwareDWGtoPDFProSettings", True)
RegKey.SetValue("OutputPDFFileOpt", 1)
Finally, I want to apply this setting to the program on four different computers (local, and three others on the network).

I couldn't find an appropriate forum which would suit the type of problem I am facing so I am putting it here.I needed to create an intranet web application that has pages with hyperlinks to eml files. The eml files as is known are email files in MIME format which outlook express can open. However what I found was if eml files are on your machine, it opens in outlook express but when opened as an hyperlink, it opens in Internet Explorer (IE) as an mhtml file. And any attachments that may be in the eml file are not displayed at all!I didn't understand why IE has to poke inbetween. After searching the net, I came across a solution that required changes in the Registry of the client machine.The change is to be made to the node HKEY_CLASSES_ROOTMIMEDatabaseContent Typemessage/rfc822.The following is a REG file that can be imported for this change.[HKEY_CLASSES_ROOTMIMEDatabaseContent ypemessage/rfc822]"extension"=".eml""CLSID"=""However after this change, though eml files opened in Outlook express, MHT files stopped opening in IE.Then I simply deleted the rfc822 node and to my surprise, MHT files opened in IE and eml files opened in outlook express and everything was fine!!But I don't want to use this sledge hammer solution. I want to know what this registry key is for and how can I set it to achieve what I want . i.e. open eml files from web pages in outlook express without affecting other file types

I need to change a value which is stored under HKEY_LOCAL_MACHINESOFTWAREAPP_NAME. It is not possible to use .NET's registry functions, since they have drastic restrictions. [Code] Unfortunately, I get a NullReferenceExeption when I try to set the value. What should I do? I have imported Microsoft.Win32 and RegistryKey doesn't accept any constructor.

I wrote an application to manage several installers and I wanted to throw in some registry settings as well. Unfortunately the following code is not writing to the registry, nor is it returning any exceptions.I'm running Visual Basic 2010 Express as administrator using Windows 7 64 bit, I can manually add the values, and I can add them from a .reg file manually but not even by calling the .reg file as a new process (it asks for permission, says it succeeded, but nothing changed).The key already exists, all I need to do is add two values.
My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWAREMicrosoftInternet ExplorerMAINFeatureControlFEATURE_BROWSER_EMULATION", True)
My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerMAINFeatureControlFEATURE_BROWSER_EMULATION", "uwgm_client.exe", 32768, Microsoft.Win32.RegistryValueKind.DWord)[code].....

We have a VBScript that launches an Access app that connects via ODBC to SQL Server - wouldn't you know the server name is changing.
Is it possible to use VBScript to modify the ODBC information in the registry to point to the new server? Basically changing one specific value for one specific key. Am I better off deleteing the ODBC key and readding it from scratch?

I am working on a app that will monitor the registry for changes to [ProviderOrder] in [SYSTEMCurrentControlSetControlNetworkProviderOrder].
I have it 90% done with this
Imports System.Management
Imports Microsoft.Win32
Module Module1
Dim Watcher As ManagementEventWatcher
Dim Hive As RegistryKey = Registry.LocalMachine
[Code] .....
If I change [ProviderOrder.test] the app tells me the value was changed and corrects it. But it does the correction twice (because of UpdateProviderOrder changing the value). I thought that using RemoveHandler and AddHandler would take of that.

I am trying to write an app to automate several things that I have to do on a new computer once I have deployed an image, hoping someone could give me some pointers for them:-
1) changing computer description - wmi perhaps?
2) changing computer name - again wmi perhaps?
3) changing permissions on an existing registry key to full control
4) changing the "time to display list of operating systems" when booting from 30 secs to 3
5) turn off simple file sharing
6) and setting current user account so that password doesn't expire - at moment I do it from cmd prompt and do "wmic useraccount where "name='name'" set passwordexpires = false
7) change power plan settings so put the computer to sleep is "never" on both battery and mains
