I would be grateful for information or a link to a clear explanation on issues relating to accessing the registry in a 64 bit system (I don't have access to a 64 bit machine so can't test). I have a VB.Net app' that needs to read the registry to find where Ghostscript is installed. This is: key = Registry.LocalMachine.OpenSubKey("SOFTWARE\GPL Ghostscript")
If the VB.Net app (made on my 32 bit machine) is run on a 64 bit machine, will it still work (assuming the key for Ghostscript is the same on 64 bit)? Or do I need to manually access the 'Wow6432Node' registry or something? Plus, are there any security implications reading the registry or can I safely assume that an installed app' will always be able to read the registry?
This shows no errors initially, but complains about not being able to convert "string()" to "string" once I run it. I'm assuming this is because the data I want is a line of string entries, but I can't find a solution.FYI, this is a project I'm working on to heal a Conficker attack at work. Our third party support has stopped the spread and healed the servers, but has now left me with the job of doing a 3 minute registry fix on each of our 400 computers, hence the attempt to automate it!
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)
I'm coding this neat little project that's kind of a hack into the SanDisk U3 Cruzer's ability to have both a CDFS and FAT32 File System. This is helpful because the program is burned to the CDFS (It's basically slip streamed as an .ISO in place of the original U3 .ISO), and the settings files (which I've developed as text files) are placed on the root of the flash drive. The program itself is VERY simple actually, except I'm having a slight issue that's really driving me insane:
The drive path of the Flash Drive won't be the same from computer to computer. I.E... The files are "UAI.txt" and "UInfo.txt". The root of the drive on my comp is "I:", but on my laptop is "F:". So if I program the path from my computer as the absolute path, an exception is thrown when the path changes on another computer. I cannot have this happen. It is probably THE MOST crucial element to this program. How can you save and read info if you can't find the files? =P
So I've gone through so many threads and forums trying to find a batch of code to allow me to make the path relative. I've found the following code (modified, of course). It works PERFECT in Debug, but throws an exception once packaged to the CDFS partition:
For a project, I need to extract all the frames of an AVI video. This I have accomplished by with free program. The problem: it took a 30 second clip and spit back 5400 some frames, and the image only changes every 20 frames or so. I really only need about 270 frames, but I didn't want to go through each one manually. So, I wrote a small program using Visual Studio 2008 and VB to open each image in binary and compare it to the one before that. If there is a discrepancy of more than 55000 (to accommodate slight errors in capturing), it leaves the file be. If not, it deletes it.
After much troubleshooting, I got it all to work. I ran it on the directory containing the images, but when it finished, only the first image remained. I checked into it, and found that the FSO loop I have set up to loop through each file was pulling the files in apparently random order. It will give me the image "bg(01).bmp" and then immediately "bg(1362).bmp" and so on. And the order changes every run.
I tried setting up an array to generate a list of all the files and then sort them, so I could pull off the name of the file, then the next one, ect. but it took over 3 hours to finish processing the array, and then It was using a huge chunk of RAM.Is there some way to "force" vb to pull off files in alphabetical order? here is my, code, it belongs with a form. fPath is a global variable, simply pointing to the source directory.
I have a program that write a key to the HKEY_CURRENT_USER (it stores an email address there & I call it later to send to that address)On form load a dialog opens & asks for email address.Everything OK on testing the program, when I deploy the application the dialog doesn't open. I assume this has got to be something to do with what references I add.I have added system & system32 but still doesn't work. The code I have is below.what references to add & if/what to copy to output directory.I'm using VBExpress 2008
I have added:-
Public Const c_strKeyName As String = "HKEY_CURRENT_USER\Software\TimWadSoftware\ServiceReport\" Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load My.Settings.Reload()
My application needs to change the default signature of outlook and I need to change the value of a registry key for this. But I get a error that I probaly don't have enough permissions. Strange thing is, if I change it manually it doesn't complain.

A first chance exception of type 'System.IO.FileNotFoundException' occurred in WindowsApplication1.exe I am bit confused by this error as I am not accessing any files but editing the registry. I am running Visual Basic 2010 (as administrator), dot net framework 4 on Windows 7.
I need to read the value of one subkey located under a list of 17,000 keys in windows registry.

Can VB 2008 use the system variable %1 that contains what filename a program was opened with? I am making a new app that when you click a .exe file and select the right option, it will edit the registry but I need to be able to keep the filename that I right clicked on so that I know what registry value to edit, is this possible?
I try to install Visual Basic 4-32bit on Vista Business but I get an error message 'VBCustom_Controls_Actions_Reg_Graph was unable to register itself in the system registry' ; is there a way to get around it ?
Trying to read key "HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsU pdateAU" value "AUOptions" and get the following : A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll Error occurs in ReadRegistry key SOFTWAREPoliciesMicrosoftWindowsWindowsUpdate AU : Requested registry access is not allowed. This occurs in my vb.net application when application is run under an account called OPER in the USERS group. The application :
1/is on my PC's hard drive, its not a web app or on a network share
2/is launched via a desktop click
3/ has a manifest specifying executionlevel "AsInvoker"
It does not occur when the Application is run as an Administrator. It does not occur if I read the value with a non .NET program when logged in as OPER whch makes me think it is a .NET problem not a registry permissions problem. Examining "Effective Permissions" shows that my OPER login has query value permission.I need the application to be able to read the key like the non .NET application while running at USERS level.
I have an installer for my application that makes changes to the registry for better application performance However, depending on the language of the operating system installed this input need changes For example (which is the case itself) Systems in Portuguese the entry is called (Padrao)Systems in English the entry is called (Default) I know I have I change the property "Condition" of the entry I created but I do not know what I have to write in this "Condition" I write within this property to validate that The system is in English or The system is in Portuguese I plan to put the project set two registry entries, one that will be done on systems with English language and other entry in systems with Portuguese language?

I've had a bit of a look around the net and on the forums but I've yet to find an answer to my question. I've got Visual Basic 2008 Express and I'm trying to write some registry entries, I can write strings fine just using
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.
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 working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
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.

Does anyone know how to use the registry section in Inno Setup to add a registry key that make a program start with windows when a Checkbox is checked in the setup wizard? If anyone know please step forward. I am getting near the launch of a program and it would be nice to include this feature.
I just bet the answer to this question already exists, however I saw no search mechanism under the forum. Anyhow, I would like to change registry data, and this code is asking for an instance to the object.
Dim RegKey As RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_CURRENT_USERSoftwa reAnyDWGSoftwareDWGtoPDFProSettings", True) RegKey.SetValue("OutputPDFFileOpt", 1)
Finally, I want to apply this setting to the program on four different computers (local, and three others on the network).
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.
Basically in visual basic 6 I could access word tables in existing templates with the code owordactivedoc.tables(1).select() where owordactivedoc refers to the active word document and tables(1) refers to the first table in the template.Trying the same code in VB 2003 just leads to errors. Secondly how do I access bookmarks or alternatively word variables.Furthermore how do one deploy web.services. For example the current program I am building is for another computer. Simply copying the web service to Inetpubwwwroot dont work because it is not picked up by the Internet Information Services program. I have to create the web service in vb2003 on the other computer change msconfig manually. Copy and paste the existing service vb file in the created folder replacing the empty vb file.
