VS 2008 - Upgrade/cleanup
Mar 10, 2011
I've had 2008 express on this PC since it came out -- I basically have ONE important project that now is being troublesome.
Just had an "unhandled exception" and "configuration system failed" -- errors I've never received before and I've just made minor changes to the program.
For one, I was thinking about a fresh install of 2010 express (but remember some real problems when I upgraded from 2005, so ??) be afraid ? very afraid?
ALSO --
What are the mandatory files I need to save in a project folder?
If I delete the bin and obj folders (plus?) and let it write new ones will that sometimes cure some problems?
What is a good way to SAFELY keep all your hard work but get rid of possible clutter and ?
Configuration system failed to initialize --

I have this basic code for cleaning up old files
Imports
System
Imports
System.Data
[code]....
The only variable is the directory path. I have the directory created and there are a few .txt files in there that should meet the criteria. However, when I run it in SSIS, I get the following error (short version) "The element cannot be found in a collection."

I am trying to format xml entries I have so that I can use the xmltextreader without getting errors. I added a default header and footer in the event I notice there is no opening or closing tags. I remove illegal characters and check for unicode but I always find an issue where an entry slips in and gives the error: data at the root level is invalid and when I check that entry is slipped through the cleaning process or just has an unmatched tag somewhere.
Now I use
Dim stringSplitter() As String = {"</entry>"}
' split the file content based on the closing entry tag
sampleResults = _html.Split(stringSplitter, StringSplitOptions.RemoveEmptyEntries)
To split my xml into individual entries before I start the cleanup process.
Here are my default headers:
Private defaultheader = "xmlns=""[URL]"""
Private headerl As String = "<?xml version=""1.0"" encoding=""utf-8""?>" & vbNewLine & "<entry " & defaultNameSpace & ">"
Private footer As String = "</entry>"
Is there any tool in the .net framework that can detect and cleanup unmatched tags so that I can get this to work.

In VB6 I have drawn lines on a picturebox and if I display another form the lines remain (I haven't drawn them in the paint event).In vb2008 doing the same the display is erased when another form is displayed.How can I reproduce the vb6 functionality in vb2008?

I have an old VB6 project converted into VB2008 express. It contains a datagrid control called AxMSDataGridLib.AxDataGrid. This is probably legacy control from previous VB versions, am I right?
The application reads data to this grid using ADO and it works most of the time. It is supposed to be read only but I cannot parametrize it correctly and sometimes when I exit the application I get an exception. Now, I seriously lack skills of this IDE and .net framework since I don't know how to get more info about the exception. The exception is just a messagebox saying something like "Key column invalid or not sufficient. Update changed too many columns". This exception comes from this datagrid.
Now, since there's a high probability that this is an old control and I cannot get the exception handled, I was thinking to upgrade it to .net DataGridView. Does anyone know if upgrading this old AxDataGrid to .net DataGridView is possible and how to do it?
I am abit afraid to just delete the old control and replace it with new since the application works and I am not attached to any source control (for reverting changes). Maybe it's possible to make a copy of this project with another name and safely play with it?

I have been using VB6 forever, but I need to to create new app versions for Vista/7, and beyond. My employer bought Visual Studio 2005 Pro a few years back, but i have never opened it.What would be the best upgrade step for me from VB6? Is 2005 adequate, or 2008, or 2010?
We primarily create apps for building and hardware controls, monitoring, logging, and communications. Will be using MySQL in the cloud with apps too.

I have a Visual Basic 6 program that I would like to update to Visual Basic .NET I am running Windows 7 Professional and have downloaded and installed Microsoft Visual Basic 2008 Express Edition. The problem I have encountered is that when I open my VB6 project file (.vbp) the Upgrade Wizard does not open. Instead, a list of references, objects and forms from my project appear. Is there any other way to run the wizard? Or am I missing something?

I know that this is not the best way of doing this, so I am looking for suggestions for cleaning this up. Currently, it only allows the user to enter Alpha characters, spaces, and press the enter and backspace key in a textbox.
'allow alpha characters, spacebar and backspace key only
If (e.KeyChar < "A" OrElse e.KeyChar > "z") _
AndAlso e.KeyChar <> ControlChars.Back AndAlso Asc(e.KeyChar) <> Keys.Enter AndAlso

After I ran a disk-cleanup (in my case AVG PC-TuneUp), the loading of my VB.net project gave error on a missing file.Changing the build-configuration (DEBUG->RELEASE->DEBUG) would recreate the file and all is OK. But I have basic configuration-info for the build, maybe in more complex cases some important details could be lost when the file gets deleted.I would think an information as critical as that, would be placed in the project folder, or be part of one of the many files that make up the project, but not in the temp-folder.

The documentation for an API I am using explicitly says that I need to call close() on an object when I am done with it. I would also like to log something there.I understand GC, might not happen at expected time, etc. etc. I still want to implement some code at cleanup.I read that I need to Override Finalize() to do this.I wrote a console app to test and it looks like it indeed works.However, this does not work with windows forms. I put a break point and it never gets hit in the Finalize method.How do you add some code to be executed at cleanup time for a window form?Here is my console app test:
Public Class Foo
Public Sub New()
Console.WriteLine("In Foo Constructor")[code]......

I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....

I have just upgraded to 2010 and i am having a problem with my first conversion. Part of the applications form load which as been converted from 2008 to 2010 is to check if a string in my settings is empty or not (databasepath), if its empty then browse for the file. If the user prsses cancel then it should close the application. This was working fine on 2008 but now it gets to Me.Close, goes to formclosing then comes back to where it was in form load and carrys on until it throws an error further down the code where it shouldnt really get to. Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.

I have written an address book and for its database, I used Access to create a .mdb database and store my data programmatically into this .mdb file.However, the problem is that when reading and saving data to this kind of database I have to use Jet 4.0 which is NOT available on 64-bit systems and I have to compile my application as 32-bit in order to run on all systems.I just want to know how is upgrade to SQL?I never used SQL, can I create a stand-alone database file using SQL like Access and create tables/fields so I can modify it programmatically?I also need the database file to be independent and don't need any special requirements to run on target systems, like the .mdb file I've created in Access!

Possible Duplicate: Best Strategy for moving from VB6 to .NET Conversion tool comparisons for visual basic 6.0 Is there a good tool anyone can recommend to convert a commercial VB6 application into a VB.NET application. I have discovered some free ones and some commercial one's, but can't find any reviews and opinions of developers who have tried and failed or tried and succeeded.
What are the complexities involved? I know that .NET uses managed code and multi threaded apartments etc whereas VB6 is based on COM.

I have a VB.NET solution that I just upgraded. It was originally in .NET 1.1, I upgraded to .NET 2.0 and verified that it would build and run correctly. Then I upgraded from 2.0 to 4.0. It is still building with no errors, but when I try to run I am getting a NullReferenceException in Global.asax.vb. The really weird thing is, the line that is throwing the exception is this:
Dim dt As System.Data.DataTable I am not trying to use the variable, just declare it. Further down a Function is called that returns a DataTable and sets the variable, but I don't even get to that line. It is throwing the NullReferenceException on the Dim line. Has anyone run across this before? Is this some issue with upgrading?

I did a Rebuild Solution before posting. This is a web application and the only files I see in the bin folder are the dll files I am referencing. I'm not sure what else I should clean up.

I've given a VisualBasic Software, written in VB5. Now the whole thing should run under Windows 7, so it needs to be converted to VB8 or VB9. It seems that most of the API of VB changed a lot in these years, so for me it seems quite impossible to run just a few code upgrades and everything is fine...
The biggest Problem are Forms. There are a lot of Forms in this Software, which are declared inside .frm files and begin always like this:
[Code]...
It seems for me that this Stuff was generated with an UI-Layouter, so none self written code is in there.Is it possible to run this code in VB8/9 or even rewrite it that VB8/9 understands it? I'm currently very pesimistic and think that the whole software needs to rewritten...

I am trying to get my conversion fixed from a VB6 application over to a VB.net 2010 application. Everything went well but for a few sleeted listbox NewIndex and OLE control.
Below are the trouble lines that could not seem to be converted:
VB6.SetItemData(lstARCurrent, lstARCurrent.NewIndex, (.Fields("approval_s").Value))
OLE1.CreateLink(strFileName)
OLE1.DoVerb(vbOLEOpen)
If anyone has any incite to correct this issue then that would be great as i have not found a way around these errors!
