Is your .MDB file part of the project?? Click on the file and check the Properties window. Does the "Copy to Output Directory" option say "Copy always"?? Change this to "Copy if newer".
The database in the bin\Debug folder is getting overwritten with the original copy of the .MDB file in your project folder, thereby overwriting any changes your code makes to the Debug copy of the database.

hi all,
i have written a service in vb.net which repeatedly processes messages in the messagequeue. i send a message from messagequeue to a server through a gateway and wait for the response. I am using TCP Client that listens to a port, to send message to the gateway(an application that interacts with the server)and receive response from the server through the gateway.
I am able to send and receive message from the gateway. The time taken to send message to the gateway is quick(1 or 2 seconds). but the response i get from the gateway takes a longer time. around 40 seconds.
The server part of coding is done by another person and i dont have permissions to that side.
How can i receive a faster response? is there anything i can do to improve it or should it be done in the server side?
Thanks in advance. 
Regards
Anuradha

The problem is on the server side.

You can't do anything to make it faster since you don't have access to the server-side code. You're completely at the mercy of the guy developing the server-side app.

If I understand correctly you need a pivot table

Hi all I've got an app that receves a XML file and then load the data in the file into sharepoint the code is as follows.
Dim i As Integer
Dim str As String = ""
'For i = 0 To XMLDocument.Length
' str = str & XMLDocument.ToString(i)
'Next
str = System.Text.UnicodeEncoding.ASCII.GetString(XMLDocument)
Dim fs As New FileStream("c:\text.xml", FileMode.Create, FileAccess.ReadWrite, FileShare.Delete)
fs.Write(XMLDocument, 0, XMLDocument.Length)
fs.Close()
fs.Dispose()
Dim xml As New XmlDocument
'' Dim re As StringReader = New StringReader(str)
xml.Load("c:\text.xml")
Dim Site As SPWeb = New SPSite(SitePath).OpenWeb()
Dim tw As SPListItem
Dim UpdateList As SPList = Site.Lists(ListBoxToUpdate)
tw = UpdateList.Items.Add()
Dim newFolder As SPFolder = Site.GetFolder(ListBoxToUpdate)
Dim destFolder As SPFolder = Site.GetFolder(ListBoxToUpdate)
Dim spf As SPFileCollection = destFolder.Files
For Each node As XmlNode In xml.LastChild
Dim ArrByte As Byte() = System.Text.Encoding.ASCII.GetBytes(node.Attributes(2).Value)
Dim strImageByte As Byte() = ArrByte
'spf.Add(node.Attributes(0).Value & "." & node.Attributes(1).Value, strImageByte)
tw.Attachments.Add(node.Attributes(0).Value & "." & node.Attributes(1).Value, strImageByte)
Next
Dim Title As String = ""
'Title = XmlFiles(x).ToString
'Title = Title.Substring(Title.LastIndexOf("\") + 1, XmlFiles(x).ToString.Length + 2 - Title.LastIndexOf("\"))
tw("Title") = "ChargeOutInvoiceNotIndexed"
tw.Update()
tw = Nothing
'spf("Title") '= "ChargeOutInvoiceNotIndexed"
The problem comes in the tw.update call the following exception is being thrown.
"To add an item to a document library, use SPFileCollection.Add()"
Does anybody know of a way around this.

Just a guess but this seems to be updating the listitem rather than adding a file to the collection. You may have to add the file to the filecollection (looks like you are doing that) and at the end refresh the list from sharepoint.

Hello All,
I have this simple question. When you write a application in VB 6. The application begins to execute from SUB MAIN.
When you develop a form application using VISUAL STUDIO.NET, I dont see the SUB MAIN in the FORMS1.VB or anywhere else in the project. Is this SUB MAIN something created automatically by VB.NET and then compiled?
I also create a module that have sub main() method but when I go the proprties of the project I'm unable to see the sub main in application startup drop down.
Note: When I uncheck the check box "Enable Visual Styles" then I'm able to see the submain in dropdown ... if possible also let me know what that means???

You will have to google the subject. With VS2008, a new class file is automatically created with the sub main procedure, but you are definitely able to do so in pre-VS2008 editions. Be sure you look into the correct syntax for the method as well as their is an attribute that is attached to the main procedure.

The sub main procedure WILL work with VS2003, however VS2005, VS2008 simplify the process by creating a separate class file to divide the work. Google the topic for VS2003, but it WILL work.

How can I hide Secret Key and Initialization vector string from .net decompiler like Reflector.net? Anybody who has the decomplier and the application's exe or dll can read my string and can decrypt the data file.
Thanks & Regards...

Encrypt the keys externally and use the encrypted version in your code. You'll, of course, have to supply code in your app to decrypt the keys so they can be used. So, no matter what you do, you cannot completely hide what you're doing from Reflector. All you can do is slow down the person looking at your code.

Hello,
I have the following. I have made a Visal Basic 2008 application that needs to be used by serveral people.
The application is connected for access thru a Touch Screen.
The problem i have i that some users are clicking on the Start button or other things outside tha apllication window.
i can set that the application uses a bigger form but still the start button , Taskbar is still there .
I am searching for a solution that only my application can be accessed, when entering the Exit button with a Code than the windows has to operate normal for maintenance.
Is there Anybody that can give me a solution
Thanks
Best regards.

open the task manager ctrl-shift-esc, note that it covers the start button if the window mode is normal (exposes the button when maximised) so:
Set your form to normal, topmost and the size to the same as the screen size - 1mm.

No. This is normally done through Group Policy. Get the Resource Kit for Windows XP and/or Vista and you'll find everything you need to setup in policies to support a "kiosk mode".

I can't see anything wrong with this bit of code. Try calling Thread.Sleep in one or both of the Threads and see what happens. This makes the Thread give way to other operations for a certain amount of time before continuing. Also, remember that unless you have multiple CPUs, a computer only ever appears to be doing multiple things at once, but instead only does one thing at a time, rapidly switching between tasks to give the illusion of multitasking. It might just be that Windows' task scheduling ends up with them being executed on at a time. You could also try lowering the Priority of both the Threads. Do they really need to have Highest priority?
