Vista (and Windows 7?) Data Storage
Oct 19, 2009
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?

We have developed an application using Visual Basic .NET as the front end and Microsoft Access as the back end. If we run the application on Windows XP we can write records to the database but when we run it on Vista it does not write records to the database.

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

i have created some shareware applications. I implemented the following mechanism for piracy protection. Before Windows Vista and Windows 7 i did write a dll file to the System32 folder with an encrypted license key. Also in the Registry under HKEY_LOCAL_MACHINE i inserted a registry key.
The problem is that with Windows Vista and Windows 7 due to the User Account Control (UAC) this is denied.
I want to ask : what other mechanism can be implemented ? Where should i store the encrypted key file and the registry key.
I want that the application can be installed for all users of a computer only once.
If i stored the key in the user's application data directory then another user could easily just install it under another user account. Also i do not want to put the key file in the application directory because that would be too obvious.
note that i create the registry key with my application and not with the installer.

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.

I develop applications in Visual Basic.NET (Visual Studio 2005) for a long time on Windows Vista without problem.
Now, I'm changing my laptop, and the new has installed the Windows 7. So, I reinstalled VS 2005, taking care to install the Vista compatibility. Thus, the version of my current VS 2005 is 8.0.50727.867 (vsvista.050727-8600) SP2. And that is my problem.
When I ran the application in debug mode (F5) on Windows Vista, a windows appeared whenever there was an error, like below:
Now, on Windows 7, the application just shows a exception message in the Immediate Windows, don't showing any error window, continuing the application execution, as below:

say you have a database that you want to store 100 different recipes in. Out of that 100 recipes 20 have 5 ingredients, 30 have 7 ingredients, 30 have 4 ingredients and 20 have 6 ingredients. So what's the best practice for storing an unknown number of items in a database?
Currently what I am doing in these situations is storing them in a single field in a database separated by a comma. Then when I have to retrieve them I split them by the comma into an array. This doesn't seem right to me but I haven't noticed an impact on speed or efficiency, so what would be the best practice to handle this situation?

I need a simple method for a user to enter as many rows of data as they wish (probably won't exceed 50 in most cases and that's pushing it) and then store that data for retrieving the next time they want to reuse that list. I will also need to read the rows in for manipulating text in a file with those entries.
Would the best method to be to use the DataSet in VB Express 2008 and then use the DataGridView for allowing the display and entry of the data?

I'm relatively new to the vb.net framework and object oriented programming. After perusing the threads for a few hours I can't quite find an answer so I'm posting this thread. I'm not necessarily looking for code examples. I just want to know if it's possible and where to look next. Basically I'm trying to build a starter application that will help me learn programming. One of the main things I want to do is to be able to dynamically (at run time) create a set of information (data) that can be manipulated via a set of static (and/or dynamic) functions/calculations. The reason I need it to be dynamic is because even though this program is really just for my own fun and perusal on my own machine (and I want it to be able to run without any outside connections (i.e. databases or servers) the data itself is going to be location (i.e.State of residence or even city) specific. Essentially most of the data will be numerical and can be of the integer type. But I'd like to be able to adjust and create new data sets if desired. From everything I've read and researched I haven't found a way to do this (at least now without an excessive amount of coding that is above my expertise). So I want to know if there is a way to do this that is relatively simple.

I am quite green to VB .NET and it start occuring to me that I am doing things probably in a very ineffective way.Anyway here is the problem I have datasets, consisting of integers there is set 1 which is of format ID, ID2 - ID here is unique but different ID can refer to same ID2. Before I start reading in the data I have unknown number of these entries (ID and ID2 can be at least as high as 99999999)
Then I have a second data set of format ID2 here is the same as in the set 1 and it can contain several PID entries (all integers). In this set the ID2 is unique and again for one ID2 there can be unknown amount of these PIDs, same PID can occur more than once.

I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).

I have an application that works fine on Windows XP. However I have taken the same application and made some modifications to it to run on vista the app loads fine etc.
the problem stems from trying to change a service in the registry under HKEY_LOCAL_MACHINESystemCurrentControlSetServicesDiagnostic Service Host
Start = 4 instead of 3 (which is what it is currently set to)
when the program tries to change it I get a dialog box with the information below. How can I makes the changes to the registry without getting these kinds of errors. I tried to get the Framework configuration tool but it talks about XP and Windows 2000 for VB.Net 2005 so I am not sure what to do... I should mention I have only been programming for a month...
Error details:
"Application attempted to perform an operation not allowed by the security policy. To grant this application the reuired permission contact your system administrator or use the Microsoft .NET Framework configuration tool. [code]...

I created an app that connects to an SqlCe database. it runs fine on my computer (xp) but when i try to run it on other computers, it crashes (on xp machine, the error is : OS error: the OS storage system is not responding, on windows 7 the error is: Access to the database file is not allowed).
On windows 7, if i right click the exe and run as administrator, it runs fine. But, i can't expect my users to do this every time they want to run my app.
