I'm using the System.IO.Packaging namespace to compress a file. I'm getting an error that says 'file contains corrupted data'. So i tried using a txt file with just a few characters, and I got the same error. I read where someone said to make sure you have all streams closed and I checked this and do so I'm not sure what to try now. Here is my code.

I'm using the System.IO.Packaging namespace in my VS2005 application. The zip compression works fine for 1 or many files. The unzip though for some reason seems to only unzip one file. Initially I did this in vs2008 at home and it worked fine, but now at work with vs2005 it's only unzipping one of the files. Can you see anything that I might be doing wrong?
Public Sub UnzipArchive(ByVal zipFile As String, ByVal UnzipLocation As String)
If (Not zipFile Is Nothing And Not UnzipLocation Is Nothing) Then
Dim zipFilePackage As Package

I am creating class libraries in my project so that I can update code without having to update the whole app.I created a class library project and added some code to it. I also added a reference to System.Data.SqlClient and also imported it into the class file.I am getting an error and I have never seen it before. Been looking online and not able to find an answer yet.

View 2 RepliesI would really like to know if there is anyway in which I can package two or more set up files together with my vb.net application; so that after installing the application, it automatically starts installing the other applications from the other set-up files.
View 5 RepliesI got a CRC checksum now and I get a Message in this Format SOH, Length Of Incoming Message, Message, CRC Checksum So I have a nice little look to processes the message and everything, Now I have questions on two events, While this loop is running it awaits for Data on the wire to come through and Checks for the SOH, I always get that but what are the chances of NOT getting a SOH, and if I don't what should I do with the Buffer Dump everything Till I come to another SOH? And on another scenario If two Packets are clashed together in one buffer should I always try to Peek and see if the Next byte after the CRC is a SOH to see if there is more Bytes and an whole another command to start Parsing and then take action?

This is a problem with MS Access, but I can't seem to find an MS Access Forum, so I'm asking it here.I have a large table of just one field. The field type is Byte. I use CTRL C and CTRL V to make a copy of the table.I then compare the Source and Destination tables and lo and behold they are different at about record number 8 million.I also tried an Append Query to append to an empty table (I haven't tried a Make Table query).But, similar corruption.The source and destination tables do not end up the same. The Record where the failure occurs varies, but it is always greater than 8 million.I tried this on MS Access 2002 and 2010 (both with an Access 2002 database).

I write text to a file using StreamWriter as shown below several times a second. The problem I have is that sometimes these files are left blank after my program has crashed or the computer has crashed. I've done several searches on the internet without any results other then writing to a second file, copying over the file and then deleting the extra file when done. If this method doesn't have any error modes it still appears to be less then a beautiful solution. (What happens if the computer crashes when writing over the original file?)Is there a more secure method for writing the text file that doesn't leave it vulnerable? This happens way too often. I never find errors related to file writing. I really want this code to be reliable enough that I could just pull the plug on the computer
Try
Dim mSW As IO.StreamWriter = New IO.StreamWriter(countFile, False)
mSW.WriteLine(CStr(totalCount))

I just published this simple console application that is supposed to show a textbox with the value of a setting called "userID" with value 1001. This works like a charm. Now what I need is to change this value outside the editor, from notepad etc. When I open the application a lot in there is non-sence etc. but with a quick (ctrl + F) I found the value 1001, and changed this to some other integer.
I ran the application again, and it failed, didn't even give any userful error-message. At a point I tried just opening a newly published non-corrupted version of the application, didn't change anything, then saved from notepad, and it were also corrupted. It seems like notepad can't open some characters or something. Do I need to publish the application in some specific text-unicode language or something? I use vb.net for this
I have a public class element from another namespace, called A, that I want to access and use in another namespace, called B. Namespace A and B are in different directories but are a part of the same project and solution. I try using the imports statement and referencing the class itself directly but it doesn't find it. Does anyone know what's wrong?

i want to select specific nodes of a xml document.Everything is ok until the document has an xml namespace. Then when i try to select the specific nodes no node is being returned.. This is because an xml namespace is declared. Is there a way to select those nodes and ignore the xml namespace ?

View 2 RepliesThis class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?
