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'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?
What is a good way to SAFELY keep all your hard work but get rid of possible clutter and ?

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.
I have a hard problem here: how to cleanup the no use memory from the RAM?

I have a container that need to add many PictureBoxes with a quite large image, then i need to clear all PictureBoxes and create some new ones. like this: If I click the button some more times, my computer will be out of ram, whatever how many ram do your computer have.How can I dispose all the things used in Graphics and the controls in FlowLayoutPanel1 but not disposing the FlowLayoutPanel1 itself?
We currently develop and deploy various applications in our business. Over the weekend, I have decided to develop a multi-use installer and update programs based on conf and command line arguments, works great.

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)
[code].....
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

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.
View 7 RepliesThe 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]......

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?

View 1 Repliesin the current project im making i've decided to add in some tools, 1 of which is a renamer based of a renamer app that already exists (called scdtoolz), i want to build my own version of it so i can learn some new things, and build a nice GUI version of it.[code]So what i have managed to determine is that the current app scans the folders contents for the CRC32 Checksum, and renames based of that, since the 456.bin's CRC32 Checksum was 2274F80B, and in the text file 2274F80B is found here 'WWF - Rage in the Cage (T-81015)(U)#2274F80B#'So now i have determined game identification is based of the CRC32 checksums, how would i go about coding a similar ap in vb.net?first i need to make the app scan a folder, but how to return crcchecksum? and then rename if check = XXXX? If MD4 sums are easier/simpler i can use those instead, im lookin at a few hash app sources now, so i think i can see how to get the md5 but not the crc32 yet, or how to rename the 2 files and folder based of the text file.
View 6 RepliesI have a question about the performance possible gains of using XML files in a VB.net 2008 windows form application. I am going to pass an XML file for parsing to an embedded resource file or into the release/debug configuration manager (app.config) file to be parsed by the same QuerySectionHandler. For performace wise, is there a preference of using an embedded resource file over the same xml in a config file?

View 13 Repliessaving required files in vb 2008, zipping it, and sending it in to my teacher via emails. When I finish the program, I hit save as and put it in a new folder. I then zip it up using winzip, send it to my teacher through our school website. When she gets it however, she cannot open it and says I don't have all the required files. I can still open it on my computer, though, and don't know what I'm doing wrong. Any advice would be helpful on what else I'm supposed to do. If it helps the program that I am doing I have to get it from a zip file she sends us, re-modify it a little, re-save it, and send it back.

I recently upgraded from vb.net 2003 to vb 2008. I see that when I "Build" the application all of the program files are generated, must like with vb.net 2003. When I use the ClickOnce publish approach, a set of files are generated including the setup.exe. When I double click on the setup file, the program installs deep down in My Documents. If I navigate to that location there is a complete set of my application files along with some Manifest files and a Manifest folder.
I wish to package my program for installation using INNO Setup Compiler, because it is very flexible and allows me to add information and choices through the installation process. My question is - if I package the "Publish" set of files, should I be including the files that are generated and located in the "Manifest" folder? and if so, do these files need to be located in their own folder as was installed on my computer? Or can I simply add them to all of the program files?

View 3 RepliesI've got a client/server communicating nicely using TCP to send text strings and to parse and act upon the messages at either end, but now I want to be able to send small files. I thought it would be as simple as reading the contents of the file into a buffer and sending that buffer as if it was a message but obviously not. When I retrieve the message at the client end I get "System.Byte[]" so its given me the variable type and not the actual contents of the array I thought I'd passed in!
My Sending code is this :
Public Sub SendFile(ByVal Filename As String)
Dim sw As IO.StreamWriter
Dim fs As IO.FileStream
[code]....
(NB I did search for this within the forum and found some examples but they just didn't fit very well with the framework of what I'm doing, such as creating a 2nd tcp channel to handle file transfers?
I need to upload a file and rename it. I have found a lot of code that uses the WebRequest for this. I was wondering if there is another method that logs in to the ftp server and will stay connected while I upload files. I am doing this for a webcam application and it seems another method would be quicker than using the credentials each time I need to upload and then rename the file.
View 7 RepliesBasically I have a known folder that is going to have some pictures in. All the pictures will be bmp for now (hoping to change it to jpeg shortly) and this directory will only contain that and nothing else.Basically I have a PictureBox on a form (pbImage) I also have a Next button and a Previous button.What I want to do is when the form is loaded read that directory and display the first image in the picturebox. Then using the Next/Previous button go through the images.I don't know how many images will be in the directory and I don't know what the names will be.

I know that on most programs that you press "F1" and the help files display in a nice form. I am not certain that mine need search capabilities since its only a couple of pages in length.
Right now, my app connects to a free file hoster to get some data. What are some better ways to host this "data"?
