VS 2008 Getting Subkeys From The Registry?
Dec 31, 2010VB.NET Private gpo_office_hklm As String = "SOFTWAREPoliciesMicrosoftOffice12.0OutlookSecurity"
Private gpo_winupdate_hklm As String = "SOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU"
Private gpo_activedesktop_hklm As String = "SOFTWAREMicrosoftWindowsCurrentVersionPoliciesActiveDesktop"
Private gpo_explorer_hklm As String = "SOFTWAREMicrosoftWindowsCurrentVersionPoliciesExplorer"

Normally, that exception is thrown when an object's value is Nothing. However, I've been through each subkey manually and everyone has a name. The only one I could think of that doesn't, are the (Default) keys.
The issue is that I can't seem to figure out how to loop through the subkeys and check if they're nothing. If I create a loop and call ".GetSubKeyNames() to check if they're Nothing, I still get the exception because it attempts to get the names before I can even check them.
Get Registry Subkeys And Create New Keys?
Oct 19, 2009I 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

File I/O And Registry :: Email Accounts Stored In Registry
Jul 14, 2011Currently, 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.
View 1 RepliesFile I/O And Registry :: Reading Multiple Keys From The Registry?
Aug 27, 2008I 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.

Registry Values Not Being Added To Registry?
Aug 4, 2011I wrote an application to manage several installers and I wanted to throw in some registry settings as well.
