Isolated Storage For Log File On XP And Windows 7
Sep 10, 2010
I'm restricted to .Net 3.5 so I can't use isolatedstorage.getfilenames() as in .NET 4. What I have below isn't working yet. I do get to the messageBox included in the code below but I can't find the file "IST_Log.txt" anywhere on Windows XP where I ran the program. I saw the messagebox appear 3 times meaning AppendLog was being called. What do I need to do to write this file on either XP or Windows 7?
Public Sub appendLog(ByVal message As [String])
' Get the isolated store for this assembly
Dim isf As IsolatedStorageFile = IsolatedStorageFile.GetUserStoreForAssembly()
Dim format As String = "MM/dd/yyyy HH:mm:ss.fff"
Dim isfs1 As IsolatedStorageFileStream
[Code] .....

I was reading an article about isolated storage and thought of doing the following.Encrypt files.Add them to Zip.Unzip the file,decrypt the content and copy all the files and folders into an isolated storage and then load a specific file into a web browser and launch lets say an HTML page I got stuck on the Isolated Storage thingy
here is a part of my code
'So far i unzipped the content of the Zip file
'Setup file streams to handle input and output.
fsInput = New System.IO.FileStream(strInputFile, FileMode.Open, _
[code]....

The Windows Application we are coding uses an XML to store connection settings etc. The application also needs to update automatically online. The problem is that the config file is replaced when the application is updated and the user has to set up the application again (definetly not ideal!).I placed the XML file into isolated storage, no problems doing that. But still when the application is updated the isolated files get replaced/removed and the user has to reset their settings..

We are building application that stores objects to isolated storage using .NET runtime serialization. Problems occur when we update application by adding some new properties to the classes of objects we are serializing. So we want to do some kind of versioning of the objects in isolated storage so we can check if they are obsolete before they are deserialized.

I have and application written that works great on XP. It is VB.Net 2008, using .net 3.5. I install and Access database to the program file directory. In Vista, I get an error that is permissions related as even admins don't have default write permissions to the Program Files directory and access creates a .ldb file when in use. To solve this, I have had the users give themselves permission to the folder.
Is that the best solution? If not, where should data be stored in Vista and in Windows 7? Also, I have an update feature of my software that will download updates to the program files folder. Is this out, too?

Looking for an idea of where the best place to keep files for a program. I use them frequently and they interact with the program directly. I want to place them in a place where they won't be easy to find if someone is just cruising thru the directories. Any ideas?

Is it possible in VB.NET to get the directory of a file copied/moved to a removable storage device?
For example, I have msword document on my desktop and move it to my storage device. A dialog box will appear or anything that will show the directory of the document.
The idea is whenever you move a file into the specific device, it will automatically processed. I will be using this to compress a file automatically when it is moved or copied to the storage device.

I put "isolated context" in quotes because I don't know what else you would call it. Basically, in C#, you can do this:
{ int i = 0; }
{ int i = 1; }
The curly braces create an isolated context which allows you to declare two variables with the same name in the same method or property logic. Is this possible in VB.NET? Also, what do you call this aside from an isolated context?

When you signon/re-signon one of the things that occurs as the system re-establishes your desktop is the re-creation of the "windows" that were open the last time you were logged on. The information is (must be) stored in the registry. My question is - where is the information stored (in the registry)? Sometimes, when my machine chrashes and I log back on none of the windows are restored. I'd like to have some kind of means to restore them to their same location and size after such an occurance. from where (in the registry) I can retrieve the information and store it (XML) for later use (using VB!)?

I need some input how to storage some information.The information I wish to store is a list (1-300) that contains the following:
-Raw material (string)
-An array of Value (double or long)
-An array of Date (string preferably)
My first approach to this was looking at the structure statement but I couldnt figure how to use the array within the structure statement.

I have been trying to do this for about a month now (hard to get answer quick because of school), but i need to decrypt a file into memory. I know you have to "write all bytes to memory" but i have two problems with that, 1. I have never touched on that itself and don't know how to write the bytes of an executable to memory, 2. I still wouldn't know how to decrypt it in memory. Right now my code is:
ElseIf entype = "rc4" Then
If File.Exists(thepath & exerandname) Then
Kill(thepath & exerandname)
[code]....
it checks if the file exist then deletes it, then it opens the file and decrypts (_4reversecr.enc) the file(Cutter(1)) with the key (key)?

I'm making an installer that needs to have information stored inside the exe itself.I cannot use my.settings because it is stored outside the application and if it is changed and the exe is moved to another computer it will reset to default.
And I cannot use resources since I cannot add/edit resources after the application is build.
Is there any way I can store and change info even if the application is moved to another location?

How do I declare and add a dynamically sized array to the class. I know that I will have to use the UBound function each time I want to add a new array.

When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.

I recently changed a For Each loop to a Parallel.ForEach loop. I'm concerned about an object being declared outside the loop but assigned while iterating in the loop. Here is the simplified code.
Dim results As ModelResults
Dim noResultsModel As New List(Of ModelResults)
Dim lock As New Object
Parallel.ForEach(_modelEngines,
Sub(model)
[Code]...
Is there a potential race condition with the results object? Would anything be different if I moved the declaration of results into the for loop?

I am attempting to add a document storage module to our AR software. I will be prompting the user to attach a doc/image to thier account. I will then put a copy of this file into our folder so that we can reference it without having to rely on them keeping the file in its original place. This system is not using a database but instead its using multiple flat files.
I am looking for guidance on how to handle these files once they have attached them to our system. How should I store these attached files? I was thinking I could copy the file over to a sub directory then renaming it to a auto-generated number so that we do not have duplicates. The bad thing about this, is the contents of the folder can get rather large.

I'm a junior VB programmer and looking for some advice on this subject. I'm trying to create a chunk of code that will create dynamic storage for variables for use later by dynamic custom controls.
For example:
An INI file might have an entry in it that looks something this:
....
[var1] <-- this becomes the Storage name
description=My Variable
type=System.Int32 <-- this could be any valid VB type
last_val=456 <-- Other code would save the last value
....
And I want to access the data using a standard "property set" like so after it's created:
var1_reference.value = 55
I've tried using a generic class which works ok as long as I declare the variables at design time from within the design environment. But when I try to create them from the INI file it gets messy.
Here's the simple generic class i've constructed to test this:
Public Class GenericVar(Of T)
'
' Generic Symbol Class for data storage
'
Private VarName As String
Private VarType As Type
[Code] .....
Also, as each object is created (and they could be different types) I store a reference in an array to make it easier to keep track of, but I'm having a hard time getting access to the objects and their properties, and certainly cant seem to assign an event handler to it once its in an arraylist because the design time code doesn't know what "Type" it is in the arraylist of objects.
