I am attempting to communicate with set of scales with a vb application that i have written using the comm control. The scales are a Kelba KHX-30 I can read the data from the scales but i have to manually press a button on the scale.
I will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.

I am trying to create a socket class in my project to send data to ecr (electronic cash register).Ecr comes with software that listens for commands on port 3535. Command are in forms of XML Files. It has only one catch, I must close the connection on socket, so the ecr would know when to process the command and respond. Since I only send one command at a time,I need the simplest solution I can get.
How it works:I create the socket and connect it to 192.168.1.67:3535 I start
client.BeginReceive
Then I send the command with
client.BeginSend
And I do a
client.Disconnect(True)
so I can get response from ECR.And in 8 of 10 times it works just fine. The problem is this few times it doesn't work.At that time I cant receive anything because it reports that the client is not connected in ReceiveCallback but it still manages to send the data to ECR just fine. The bill comes out on the ECR, but I get no answer about what happened.
I call the class like this:
Dim dre As New HCPSocket Result2 = dre.Otkucaj(Command1, "192.168.1.67") Debug.Print(Result2) dre = Nothing
End the class looks like this:
Imports System Imports System.Net Imports System.Net.Sockets
I'm using server.transfer to transfer execution of a URL to a dummy page which fetches information from the database. The trouble is that the master page interacts with the session.
global.asax: Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) ' Fires at the beginning of each request If Not (System.IO.File.Exists(Server.MapPath(Request.Url.LocalPath))) And Request.Url.LocalPath.ToLower
[CODE]...
Master page: If String.IsNullOrEmpty(CStr(Session("SessionId"))) Then
I'm getting an error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I should also mention that this same master page works elsewhere in the site. Session is used throughout the site as well (not just in the master page).
I am new here; say to everyone first.Here is the a question for coding list box; it has two part: first part: Create a project that stores personal information for a little electronic "black book"; the fields in the file should include name, phone number, pager number, cell phone number, voice mail number, and Email Address. allow the user to enter the data into text boxes. (This part is very easy, The trouble maker is in the second part).
second part: create a second project to load the names into a list box. perform a "Look Up" and display the appropriate information for the selected name. The second part should be very easy to someone here; please write codes, I have stuck in the second part for couple of hours.
how can i capture a signature from an Electronic Signature Pad and store it in database. is there any particular api or it can be captured just like capturing an image from a WebCam. Is it manufacturer specific?
I thought you couldn't run an EXE from a web page, you had to download it. How can it be that ClickOnce lets you choose online-only? Does it temporarily install the EXE on the users computer?
If I want my application to run online only and I use the publishing wizard in Visual Studio, how do I get the whole install thing onto my website? Do I upload something onto my site using FTP?What do I upload onto the site? And once the files are on my website, what file does the user access to run my application online?
I have a customer that does not allow for local installation of any version of MSDN so telling me to press the help or F1 key in VB6 will not help. What I need is a link to VB6 IDE functionality (ie all of the special characters in the find dialogue to help in searching or how to effectively use "use pattern matching" when I press CTRL+F).
My friend s doing an online project...He wants to know how many users(REGISTERED) are LOGGED-IN CURRENTLY in his site...i.e if i'm ADMINISTRATOR of this DANIWEB, i want to know the USERS CURRENTLY LOGGED-IN...
I am developing and application in vb.net winxp+ (windows xp upwards). The application has to receive backup data from clients software located at different pc over the Internet. but am concerned about security of this application on the Internet. what would be the best way to implement security in vb.net 2008 to make sure that the data is not sniffed or interfere with?

I friend and I are trying to work our way through this, and right are having some issues in terms of getting vb.net to connect to an online sql server. We have found lots of resources to connect to local sql servers but nothing about connecting to an online one. I was wondering if this is possible as we are trying to be build an inventory and pos system for a small company we have, which can be accessed through the vb program from any computer as long as it has an active web connection.
How do you connect to an online database? Let's say it's located at www.abc.com/app_data/thisfile.mdb. What would you enter for as the DatabaseFile in the following code?
Dim DatabaseFile as string = ???? Dim connection_builder As New OleDb.OleDbConnectionStringBuilder connection_builder = New OleDb.OleDbConnectionStringBuilder connection_builder.DataSource = Me.DatabaseFile connection_builder.Provider = "Microsoft.Jet.OLEDB.4.0" connection_builder.Add("Jet OLEDB:Database Password", Password) Return New Data.OleDb.OleDbConnection(connection_builder.ConnectionString)
Our database has been having some occasional troubles and this seems to be presenting a problem in my new app. How should I test to make sure the database is up before sending SQL statements to it? We are using Oracle 11g and I am using odp drivers, VB.net 2010, .net framework 4.0.
I have an application that when it starts, it checks the internet to see if a new version is available. My problem is this: If there is no net connection, the program 'pauses' as it tries to check for the new version.
