Accessing MultiString Data From The Registry?
Dec 15, 2009
I'm using VB 2005 Express Edition.I'm trying to use VB to do a few things, the first of which is to display the data behind the registry key at;
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost\netsvcs.
The data I want list should look something like:
6to4
AppMgmt
AudioSrv
Browser
[code]...
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 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?

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)

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've an application that's uploading data to a server. Occasionally the server returns a 403 response from a call to HttpWebRequest.GetRequestStream(). The response contains more data than simply the response code, but I can't figure out how to access it. Is there a way to do this?

So I'm a little rusty on my VB.NET skills, but I decided to take up a project to get me working in it again. Problem is I've hit a slight road block and I was hoping someone here might be able to point me in the right direction.I have a spreadsheet (or 3, but they could be combined if that makes it easier) that contain interest rates. I need my program to use user-input to select which interest rate it needs and then calculate and output the grand total, without the end user ever seeing or even being aware of the interest rate table.

It's all fine, accessing files and directories by using a dynamic link library (DLL), but is it possible to do online?Suppose I want to parse a file, which would normally be simple in visual basic; is it possible to call functions from a DLL using a server-side language, say PHP?

Is it possible to add, edit, view and delete records using a file only (instead of a database) and .Net 2005 (VB.Net/C#)? The concept is that a file that'll work more-or-less like a database. One can add, edit, view, delete and query data to and from the file. The file, either cannot be opened directly or data inside the file should be in some encrypted form so that even if the file is opened no one can comprehend it. Data inside the file can only be manipulated by a front end application i.e. .Net 2005.

New to VB.net, and trying to re-factor an 'old-skool' ASP page where all the page logic is happening on the .aspx page itself, to code-behind. Basically, I have a button that has a state, either on or off. If on, I set a hidden field to 1, if off, I set it to 0 (the default when a user visits the page).The goal is to simply change the message I am sending to the user.[code]The above code produces the following effect: when I click the button, setting the state to 1 and the page reloads, in Page_Load, I am getting zero results from the If dlList.Items.Count > 0 Then check, and thus am showing the 'No results' message, but the actual asp:DataList on the MyPage.aspx page is returning results... and then if I click the button again, setting it back to 0, in Page_Load, the datalist is now returning results, so I set the text to 'Results', but again, the control on the MyPage.aspx page behaves correctly, and shows no results, as expected. Now keep in mind that the above works perfectly in terms of checking the number of results if I move the If dlList.Items.Count > 0 Then page logic out of Page_Load and back to the MyPage.aspx file, it all works fine (i.e. results when state = 1, none when state = 0)

My problem is that i have a usb-to-serial device which creates a virtual serial port ( Com 4 for example )on the computer i need to connect to it and get the data stored on it I already have worked out how to use the System.io.ports to connect to the port ( baud rate, stop bits, parity ,ect) and it connects to the usb fine. But once the connection is open i don't know how to retrieve the data. Everything i have tried relies on events. But as the usb does not send data i don't know how to access the serials memory.

I have written lots of code with the ADO Library in VB Excel and previous versions of Visual Basic. With the dissappearance of the recordset object, how do we perform data manipulation with an attached Access Database? It seems things could be a lot easier, and less complicated by now, however, the best methods appear to currently remain ellusive.

I've got a website and we just had a huge jump in traffic. Now all of the sudden we're getting sql parameter errors left and right. We switched to a new sql server a few weeks ago and everything has been fine but the added traffic seems to be breaking us.I have a data access class that is called when each user trys to logon. It runs through several tasks before finally updating the users last login date and forwarding them to the administration section.
What I'm seeing from the trace logs suggests that when I'm logging in the first several tasks are using my data (lets say user=birk pass=word). But at some point the accessor class starts sending over the data from someone else who's trying to login (lets say user=abcxyz).Every connection we make to the server is closed when we're finished with it. I'm nulling out all of the accessor objects when I'm finished with them. But somehow different user data from different sessions are making their way into other peoples instances of the object.
I'm not using session/application/cache/viewstate to store the objects so I'm not really seeing how they could edit eachother... Its just really weird and I'm not sure how to even go about researching the problem.This is roughly the accessor class... I trimmed out some of the parts that weren't reliant to the issue

What is the standard method for accessing back end data, which logon should you use? For example we have applications that require the user to login but then use an admin account to access the data from the backend.But there are also applications that require the user to login and use those credentials to access the backend data.We are in the process of creating an application that will require the user to login and would like to implement the more common method(standard practice) of accessing data.If there are alternatives those are also welcome.This will be made in ASP.Net 3.5 or higher and may include Windows Applications(VB.Net) as well.I dont want to have two sets of credentials. What I am asking is which credentials are normally used to access the Database. For example one one application may access 2 or more database's. Now would you use the same credentials they used to login to the application or would you use the admin account to access the data?Maybe this should be a seperate question but if I ended up using integrated security to access the database would the user be able to simply connect to the database using his AD account? Either through an ODBC connection and MS Access or equiv.

I am an old VB2 programmer and in the process of moving up. In VB2 I could obtain a data row via and index on an access table. I can not find an example on how to do this. I can retrieve a single row using a query, but an index would be faster. I know in Oracle use can use a hirt to direct the query to use the index.Here is what I was during in VB2 (Sample) with no hint.
Set Stock_Tbl = "DataBaseName".openTable(Stock_Tbl_Name)
Stock_Tbl.Index="Symbol_Idx"
Stock.Tbl.Seek="MSFT"
