VS 2008 : Delete A Registry Key?
Dec 29, 2009
i made this Reg key with this code.
Registry.SetValue("HKEY_CURRENT_USERSoftwareapp", "Sample", "001010101")
I'm trying to delete the Name of the Key and the value only with this
My.Computer.Registry.CurrentUser.DeleteValue("Softwareapp")
But i think this will delete the folder and not only one key Do you know a code that would only delete
"HKEY_CURRENT_USERSoftwareapp", "Sample", "001010101")

I'm making an application, that makes any file you choose to run at Windows startup.I add the value "HKEY_LOCAL_ MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun" with a button and all is perfect, I reboot the pc and the file runs properly. But the problem is, in the application I also include a button to delete this value, but the test button tells me that there is no value. I use
"Registry.LocalMachine.DeleteValue(ComboBox1.SelectedItem)". Also I try
"Registry.LocalMachine.DeleteValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun " + ComboBox1.SelectedItem) but what it does is try to delete a value with that name, and don't go to that key and delete the value.

I have a test registry key I created in HKLM within software called test. Within it a key called innertest. When I try to delete it says key doesn't exist.
My.Computer.Registry.LocalMachine.DeleteSubKeyTree("Software est")
I am using VB 2008. I believe it might have to do with not being able to access the true registry due to not running the app as an administrator. How can I force the app to run as administrator?

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 am trying to code a delete button for a browsing program based on data from a txt file. I have coded the buttons to sort(ascending and descending), append to the text file, search the text file, but I can not seem to get the delete function working. I am using VB 2010, this is what I have so far:
Code:
Dim deleline As String
Dim line As String
Dim isFound As Boolean = False

I have a project where you type something then it looks through a text file for what you typed. I would then like to make a way to edit the text file once I find what I'm looking for. So, how do you delete text from a .txt file that you are searching through? Also, how do you re-write in that place you just deleted the text from?

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've got a .reg file and I want to add it to the registry when the user clicks a button. I've been searching the forums and I've seen allot of ways to do it without the .reg file, instead taking the values and putting them in the correct syntax, but I already have the .reg file and it would take far too much effort to place all the values in the correct syntax (The amount of values is huge). What is the code to do this? Do I have to somehow add the .reg file to the project?

I have a section of code that will compile perfectly using VB Studio 2003, but it throws a InvalidCast Exception under VB 2005/2008. The code throws an Invalid Cast exception at KeyHandle = e(field.GetValue(KeyToMonitor) line below, and as far as I can tell it is because the variable Field is passing the string Microsoft.Win32.SafeHandles.SafeRegistryHandle rather than an integer. Is this because of safe keys in VB 2005 and 2008?
how to call the handle of the registry key opened in a way compatible with Safe Keys? I'm using the code to notify when a registry key is changed using RegNotifyChangeKeyValue.
Private Function WaitForChange() As Boolean
Dim notifyEvent As New Threading.AutoResetEvent(False)
Dim KeyHandle As IntPtr

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.
