I'm trying write a code that will check the framework version on the same computer it runs.
Now this code has to be able to run on every machine regardless the frameowrk version on it.
Now, i know how to read one registery key, but i don't know how to check muliple keys.
For example "HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDP"
Under the key "NDP" there are a couple of more keys, how can i get the keys name?
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.
How can i make and read a registry key? my program creating a registry key (on the first run) and later reading it to see if it is registered or not. any suggestions on how i can manage this?
i do know it goes something like: my.computer.registry.currentuser.createsubkey, but im stuck making it and i have no clue as to where to read it...
--ThrDude--:P If it is not worth it, it is not fun - you say programmers are boring but i say they are worth it.
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.
I am trying to read keys and values from the registry. The keys I am looking for do exist in the registry, but the variable mRegKey is still Nothing after the first line is run.I have also tried different keys under HKLMSoftware, some work and some dont. HKLMSoftwareATI is found but HKLMSoftwareOracle is not (both are shown in regedit).[code]
View 3 RepliesI am trying to list all printers (PrintersConnections) under all users (HKEY_USERS)
problem is I dont know the user name keys in advance and need to exclude .DEFAULT and *_CLASSES so first I need to list all key names (%usernamekey%) directly under HKEY_USERS then for all keys that lists lsit all keys under HKEY_USERS\%usernamekey%PrintersConnections
Here is the code I have so far but I get errors about object variable not set, I suspect because of the way I doing the for each and listing the key names and then doing it again
Code:
Private Sub DetectPrntrs()
Try
Dim RemReg As Microsoft.Win32.RegistryKey
[Code].....
this works partially but if I close the reg key as shown I get an error [code]So my question is how/where do I place the Myreg.close and OldReg.Close commands???

I want to get all sub keys in a reg location. This entry can also have additional sub keys.At location "HKEY_CLASSES_ROOTexefile" this key as 3 subkeys and 2 of these keys have additional sub keys under them. I need to get all the keys and any additional sub keys under each key if there is any. This code will be used for other keys, so I can not assume they have subkeys.
Dim Key As RegistryKey = Registry.ClassesRoot.OpenSubKey("exefile", False)
Dim SubKeyNames() As String = Key.GetSubKeyNames()
Dim Index As Integer

I'm trying to access a registry key that has a space in it, specifically:
SoftwareMicrosoftWindowsCurrentVersionWindowsU pdateAuto Update The key is valid and I believe the code is, though I can't get any keys with spaces to open using Registry.OpenSubKey
The following code fails only for keys with spaces: subkey = New String("SoftwareMicrosoftWindowsCurrentVersion WindowsUpdateAuto Update")
m_hive = m_hive.OpenSubKey(subkey, False) Dim val As Object = m_hive.GetValue(key)
Ok well i wasent quite done. (For thoughs of you who dont know what im talking about i just made a post few minuts before this)
Ok my LAST, LAST, LAST Q *few* Is there any way to dissplay registry keys in a listbox? And can i edit them within vb?
I want to export some keys that located on different hives in Registry to a file, but the command below only can export a key.
Regedit /e <file name> <key name>
How to export multiple keys to a file? can the api RegSaveKeyEx do that?
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
View 18 RepliesI 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 ?
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.
then there is two radio buttons one says enabled and one says disabled what they do is check the registry after the button has been clicked on and depending on if the registry is set for 0 or 2 0 for disabled 2 for enabled...
I've tried various ways but I cannot get the radio buttons to check properly
I am wondering if there is a way to get the keys from the registry and display them in a checked listbox. For example I want to get all the keys and there values from "HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun". This will allow me to see all the startup items. Is there a way that I can get all the values and display them in a checked listbox. I tried using the GetValue but it seems that you have to set the key that you want.

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 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.
I have setup my listview to View: Details
I want the listview to show all the keys of a specific folder.
Example: HKEY_CURRENT_USER\Software\Microsoft\VBExpress\10.0
So you click button1 and it adds all the keys within the example to your listview.
I am trying to creat a program to automate many of the things I do when I build a computer. I was attempting to do this via batch files but got stuck when I needed to search the registry for cetain keys and delete the parrent folder in which it resides in.
For instance: Installing a MS Loop Back Adapter I found a utility that works at the command promt called DEVCON that will allow me to install a MS Loop Back Adapter. I was doing this through a batch file but found that I can call the utility through VB and get the same result (of course I still need to have the DEVCON.exe)

I'm having troubles reading the values from a registy key, basically I already have my code working which reads back data from a registry key with the name "data" however I also have another key called "data+" and when I attempt to read that the "+" get ignored and it reads back "data" which is in the same location. I have no power of changing the reg key, do I need to convert the + into hex or something like that, if so how do I that and then read it back?

I'm creating a project that involves hot keys, but it requires multiple hot keys instead of assigning one. I'm going to make it so if a user presses for example CTRL + T on they keyboard while a textbox is selected, it'll show CTRL+T in the textbox and assign the key to do something. How do I do these though? Here's the code I've used for single hot keys:

View 4 RepliesI need to read a value (and possibly adjust the value) in HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall key on both 32 and 64 bit systems.I've tried accessing 'stuff' by compiling my widget as both a 32 and 64 bit app, but nothing is working. Then I came across some information indicating that this could be done from a 32 bit applicaiton using KEY_WOW64_64KEY [URL] somehow, but I can't figure it out.
1) Check the existing value of HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall{ProductGUID}DisplayVersion handling both architectures.
2) If the value <> "" And <> Our Current Version Then
3) Write the Current Version to the value mentioned in step 1.
I wouldn't think this is that difficult as I've worked with registry before, but the 64 bit stuff is throwing me for a loop.It would be nice if I could compile my app to target AnyCPU then detect where its running on 32 or 64 bit. The app could then look and update in the appropriate location.I currently am set to use .NET 2.0, but could go to 4.0 if there is something in there that makes the above tasks easier.
I'm trying to understand how to get a string from the registry. There are a lot of walkthroughs, and information about retrieving known strings, keys. But what about if the value changes or could be unknown? For example, I wrote some values to the registry:
[Code]....
The txt1.Text information will differ so I can't say it is a definite string. The txt1.Text will be created based on information entered into the form and then it is encrypted. It will be unique to that user, but I want to compare the string in the registry key to one in a textbox on the form.
