I have the following code, I was wondering if anyone could show me a way to clean it up abit, it's a bit bulky and repetitive and I am just looking to slim it down.
Public Sub RefreshList()
Dim Button As New ListViewGroup("Button")
CodeKeeper.lvCodeList.Groups.Add(Button)

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

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 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=""http://www.w3.org/2005/Atom"""
Private headerl As String = "<?xml version=""1.0"" encoding=""utf-8""?>" & vbNewLine & "<entry " & defaultNameSpace & ">"
Private footer As String = "</entry>"

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?

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?

View 1 RepliesAfter 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.

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one! Am I doing something wrong?[code]
View 2 RepliesWondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

but if the checkbox is not checked then i want it to wait until it has copied the file before deleting it because at the moment it deletes it quicker than it copies it and the file could be different size everytime so i cant just put a simple timer of say for example 5 seconds in.
I am learning VB for the moment. I want to copy/paste code from a PDF to Visual Basic 2010 Exppress, but if i paste the (structured in PDF) code to VB, i get 1 long string of code and need to restructure it by entering after each line. Otherwise VB gives me a lot of errors. This is a time consuming work. Isn't there a way, VB puts the code in the right format?

Prior to VS 2010 I was able to debug VB6 client code from the .Net IDE by setting "Start External Program" to vb6.exe (full path), or attaching to the running vb6 executable via "Tools->Attach to Process" and have execution stop at the required breakpoints in my .Net code.
Now with VS 2010 I seem to be only able to accomplish the same by setting the target framework to 4.
Is this a bug in VS 2010, or is there a switch/option that controls this?
At my old job we used batchscripts to start macro's in another application. These batch scripts would also write data about the status of the macro as loglines to a log file using VB.
I have saved the batchscripts when I moved to another job because I always thought they might come in handy. However I forgot to save the visual basic script needed to create and fill the logfile.
The batchscript would look like this:
SET SP=C: est
SET LOGFILE=C: est est.log
cscript //nologo %SP%logging.vbs "Script executed by admin" >%LOGFILE%
cscript //nologo %SP%logging.vbs "Starting Loading Data" >>%LOGFILE%
