i have problem with searching key value in registry I have that
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim itm As ListViewItem
Dim root As RegistryKey
Dim searchkey As String = TextBox1.Text
[code].....
But on line: For Each valueName As String In root.GetValueNames, it says: Object reference not set to an instance of an object.
I'm trying to:
Check for any unused data in the registry relating to MS Loop Back Adapters and remove it
Install New MS Loop Back Adapter
Remove some of its bindings
Remove the Show Icon
Adjust the order of the network adapters
The issue I am having is finding a way to search all sub folders with in a certain folder in the registry. This is the code I have so far
Dim x As Integer
Dim NetworkAdapterLoc As String = "SYSTEMCurrentControlSetControlNetwork{4D36E972-E325-11CE-BFC1-08002BE10318}"
'{1535ADE9-7E74-4508-951F-30F23A29B5A4}" - This is on of the subfolders I want to look in on my machine
Dim RegKey As Microsoft.Win32.RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey(NetworkAdapterLoc)
[Code] .....
I even tried to replace the
MSLoopLocKey = RegKey.OpenSubKey(subname(x))
with this
MSLoopLocKey = RegKey.OpenSubKey(NetworkAdapterLoc & "" & subname(x))
But in either case I just seem to list the sub folders I actually want to be searching. A lot of the tasks I want to accomplish with my application will require me to search through multiple sub folders in the registry and either modify the data in a key or remove the entire folder.
I am trying to do a query on the registry for uninstallation of a program but dont know where to start.The structure would be like so:If {123-456-789} exisits in registry then run Msi.exe /x {123-456-789}therwise run
View 2 RepliesI 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 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].....
i am working on a VB project for Chem and im making it for converting grams to moles, moles to molecules or any thing like that. and i have about 110 elements set up and working fine the way that im doing it but i have a feeling this is a horrible way and to abundant.
i have a textbox set up to if i type in the element He and hit enter it will find ChemElement(1)="He" and it calls "Sub DisplayElement(ByVal number As Decimal, ByRef label2 As Label)"
Which then displays the Chemical mass into a Label.

I have a program which grabs the source code of a webpage and puts it into a string. I would now like to search the string for two values.
"video_id": "value 1 here"
"t": "value 2 here"
The problem, is that I don't know the position of the values, and I the values change depending on each webpage. All I know, is the text before the value, e.g. "video_id" and "t:"
Here is my code:
Dim videoid As String = TextBox1.Text.Trim
Dim wc As New System.Net.WebClient()
Dim result As String = wc.DownloadString(videoid)
I do not know if it is possible to implement this problem in VBA or it must be done with VB. Net using Visual Studio.
Problem: Excel has its search function and it is a pain if there many value available or you must find a value that far away from column A.
I would like to have something like this
In which I can specify what columns I want to display by their header name. Rearrange the column in the way I would like to, and ability to copy and paste. Like datagrid in Visual basic?
I am using VB.net 2003 application program. I am trying to do a select statement whereby I'm searching between 2 datetime values that are being stored as datetime. records are stored inside Access. For example, I am searching between 2 datetime:
StartTime = 2/23/2009 9:00:00 AM
EndTime = 2/23/2009 11:30:00 AM
So I need to find all the records in between 9:00 AM and 11:30 AM on 2/23/2009.
strSQL = "select OrderID from Orders Where OrderDate >= ('" & StartTime & "') AND OrderDate <= ('" & EndTime & "') "
but i got the error showing below:
An unhandled exception of type 'System.Data.OleDb.OleDBException' occurred in system.data.dll
strSQL = "select OrderID from Orders Where OrderDate >= DATEVALUE('" & StartTime & "') AND OrderDate <= DATEVALUE('" & EndTime & "') "
But when I use DATEVALUE, it takes the date from the string and set time as midnight (00:00:00). So it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
strSQL = "select OrderID from Orders Where OrderDate >= TimeValue('" & StartTime & "') AND OrderDate <= TimeValue('" & EndTime & "') "
And when I use TimeValue, it returns the time from the string and set date as jan 1st. so it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
but none of the codes above is returning records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. i searched and found all those examples. but that didn't work. Is there anyway i can search between 2 datetime values. i need to find all the records that lies between that time period (for example: between 9:00 AM and 11:30 AM on 2/23/2009).
I have to scan through documents. Excell, Word, txt, ect looking for company names that match a pre-difined list of companies.I then email the companies some specifics in regards to that doc.The problem I have been having recently is that the list of companies keeps growing and I am starting to miss some more than I used to.What I would like to build is a tiny app that has 2 Text boxes.1 on the left for input (where I would copy/paste) the document text I receive.and one on the right for the output where it will highlight any line that contains the name of any of the pre-defined companies.
I started toying with the idea and so far I have form with a SplitContainer. Within that SplitContainer each side has a TextBox... Below the Textbox on the left hand side splitcontainer I have a submit button with no actions currently assigned to it.
Is there any way I can open a registry file that is not from the local machine? I have the software and system files from another PC and need to create a small code to read and get values from the files. The other PC is down and I just have the registry files so I ruled out the OpenRemoteSubKey method. However, the My.Computer.Registry.GetValue only works on the local machine.

I have tried to solve this myself and I know I am probably doing something really silly here what I have is two different registry values that control what is displayed in the combobox on my form RegistryKey1 has the following values:0,1 or it does not existRegistryKey2 has the following values2,3, or 4 the combobox has the following values 0,1,2,3 However here is the problem if the RegistryKey2 is 2 then it further has to be checked if RegistryKey1 is either 0,1 or does not exist
if it is 1 then the selectedindex = 0
if it is 0 or does not exist then the selectedindex = 1
if RegistryKey2 is 3 then the selectedindex = 2

I am a newbie so please forgive me if my terminology is incorrect.I am trying to Update a Registry sub key value. I have done this a few times before with success. But this time is kinda different. I noticed a few things,like the sub key value is in HEX when I export the key (The value that I want to input is from a sub key that I exported) I can only get the registry to accept the command if I do not specify the registry value kind, but that doesn't do me any good if its not the correct value kind.

View 1 RepliesI 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 want to enumerate all of the values within a given registry subkey (for example 'HKLMSoftwareMicrosoftWindowsCurrentVersionRun')

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.
View 1 RepliesI 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?
