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 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 ?
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 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 VB.NET console application that must write a message onto a queue (resides on the mainframe). We have all the clustering and everything set-up by our admin. We already have an existing windows service that successfully listens to messages and also writes messages to various queues.I have basically re-used most of my code from the windows service project.But when I try to access the queue manager, I hit the exception "MQRC_HOST_NOT_AVAILABLE". The error log from the Websphere MQ folder says

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?
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 am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?

I've got a problem whereby I get Permission Denied while accessing a database via OleDB. I know how to unlock this but i'm not permitted to do so. I was wondering if ODBC would work? I'm not sure on the settings around this on my the PC where I'm going to use this application but wonder if this has less security around it. your thoughts until I can test this next week. Or is there another way you may know that I can use a database. (access)
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?
In all the years that I've been coding I have never come accross this issue or error. For the past 3 months I have been working on two separate apps. Initialy I started out with Win Vista and things were going great except for how slow my comp was running. So I reinstalled the Vista OS. Everything was going great until Mar 7th when this error just started occuring within my code.
"Access to the registry key 'HKEY_CURRENT_USERSoftwareTornadoAppsSwift BudgetUser' is denied"
TornadoApps/Swift Budget are strings created upon App install or first run of App in VB 2008.The User value along with 9 other values were all working fine prior to Mar 7th.Now this line along with many others like it with defferent strings and values were working just fine till this week. So i figured that I'd just upgrade to Win7 hoping that would fix it. IT didn't. So I reformatted and installed fresh Win7 and still have the error. So I have figured out that it isn't my OS. Cuase it was working in Vista then just quit working.
"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll" when writing to registryI write to the registry quite often in my program (Around 10 times every 12 seconds) the error doesnt constantly pop up sometimes it can save 20times and on 21st ill get the above error. How can i fix this. Is it because im saving so often?
