I know I'm not the only developer experiencing this issue but only within the last month I started receiving Visual Studio 2010 hangs while running running a simple ASPX web project within the IDE. On stopping the execution or closing the web page VS2010 hangs and becomes completely unusable - stating that VS is busy. It never returns and I have to stop the DEVENV process, resulting in a complete shutdown of VS.
Until now (1 1/2 years) I've been developing a Winforms application with no issues, other than VS2010 IDE errors that have been documented and I've been able to work around. Now, like my Web project, I am also experiencing the same hang but not as frequently. Other documented cases is this forum don't apply in this case since I'm not working with an IIS web site.
Additionally, in reading the forum messages I notice this issue has been around for years and has caused a great deal of grief and delay to many development projects. I'm running Win7 Pro, VS2010 pro on a Pentium Dual-Core CPU 2.20 Ghz with 4 GB memory laptop running in 32 bit mode. I'm very concerned at this stage of the process to upgrade to VS2010 SP1 since I've read too many horror stories online and can't take the risk of affecting the only support environment i have for Winforms application that is currently in production
I have a button on form 1. When the button is clicked, form 2 pops up. Form 2 also has a button.
Code for form 1:
Imports System.IO
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim textfile As New FileStream("textfile1.txt", FileMode.Create, FileAccess.ReadWrite)
Dim txtfilewriter As New StreamWriter(textfile)
[Code] .....
Now, as you see, on the form 1 load event, the streamwriter writes "Physics" to the text file. When the button on form 2 is clicked, the streamwriter writes "English" to the same file. As an end result, I expected BOTH "Physics" and "English" to be in the text file but the final result is only "English" in the text file. What do I have to do so that the textfile continuously stores these lines?
I am trying to uninstall VB express 2005 but keep getting an error that it cannot complete.

I'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.

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?

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)

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?

View 1 RepliesI 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.

View 5 RepliesThe 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..
View 1 RepliesI have an idea of making a chat program with someone over the internet. So my understanding of what i have to do is create a server that holds a text file that can be manipulated by both parties. Then create a program to read the file and change it.

View 5 RepliesI'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'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.
