View 1 RepliesI'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.

View 1 Repliesi 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")

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 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?

View 3 RepliesI'm having a hard time determining if a registry exists or not.
This is what I'm trying:
CODE:
The registry key exists on my PC, so I'm having a hard time debugging it on another PC. When it threw the error, I commented out the last block of code to see if I was checking the key wrong or if it would throw the error just on the variable declaration.
Which is did. I get why it did. You can't .Open a key that doesn't exist. However, I looked it up and everyone is recommending that we do it this way. But this way doesn't exist.
I need to add a value to the registry for the runonce key but I keep getting this error:Argument not specified for parameter 'MainKey' of 'Public Function BungeRegValue(MainKey As Microsoft.Win32.RegistryKey, sKey As String, sKeyName As String, oNameValue As Object, RegType As Microsoft.Win32.RegistryValueKind) As Boolean'.Creating the Function is fine but I get the error when I try to add the function to a button click event

I have access to VS 2010 through work and I'm having a bit of a play. I'm trying to create a small program to show the installed software from GP and have the ability to delete a selected registry key from a list. Am using a checked list box and 2 buttons. Also have 2 labels on the form but just using them as a visual check as to what the string says.
The program starts alright and gives the list of installed software from Group Policy. I'm having the problem deleting the ticked item. Here is the code I'm using. I think the problem is when it comes to the .deletesubkey line and what I have entered. I want it to delete the selected item rather than have the specific key name entered.
Imports Microsoft.Win32
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

I am trying to change the permisions of the following registry key from within VB.net:-
HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSLicensing
Basically need to change users to full control. I need to change permissions for the "users" group.
When my program first launches, it generates a GUID which is then saved to the registry and compared to an online database when an internet connection is detected. If it is a valid registry key, another registry value is saved stating that it is valid. Is there a way to protect these 2 registry entries from being changed?
