I'm a beginner user of Microsoft Visual Studio 2008 and I want to ask what would be the initial code to connect a Visual Basic 2008 form to a SQL Server compact 3.5. I want to create an add new account program using the above applications.
View 1 RepliesI am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.
I've developed a software using VB.net and SQL server 2005. This is the connection string that used. Data Source=MY-PC\SQLEXPRESS;Initial Catalog=studentInformation; Integrated Security=True But now i want to use SQL server compact edition. So what should i change in this connection string?

View 1 RepliesI am attempting to connect to Microsoft SQL Server 2008 R2 from within Microsoft Visual Studio 2010. My connection string is as follows:
connection = New SqlConnection("Server=localhost;Database=greenapplication;User ID=WindowsID;Password=WindowsPassword")

I am looking into writing a web-based vehicle tracking system. The framework I have in mind looks something like this:
Client application --- Database --- Database updater.
Client application: This would query the database for information and then display this information on a map.
Database: holds vehicle information such as speed, location, payload etc.
Database update: This application would need to continually check for information received from vehicles and then add that to the database.
I am confident that with my current skill set and some research and learning, I could write the client application and interface it to a database. However, I am at a loss as to how to write the database updater. Presumably, this would be an application running continually on the server, waiting for information to be received from vehicles and updating the database. Is this something I can do with ASP.NET and Visual Basic? Or would this require a different way of thinking than writing web pages?
Would it be something like this

View 8 RepliesOne of the client requirements is that the server generate files and store them on a special folder. This files created can not be modified by users or deleted.So the only way I thought is to generate this files with elevated privileges so a normal user can't delete or modify them.But the question is how can I generate a file with this privileges that normal users can interact with this files... only download from server.I use this code to generate the file... But I don't know how to configure it for elevated privileges.This is the button which generate the file and allow to download it:

View 4 RepliesI am a brand new user of MS Visual Basic 2005 Express and MS SQL Server 2005 Express. I have familiarized myself with both programs but have one extremely frustrating problem. Once I open SQL Server, I can not establish a database connection from Visual Basic using the Visual Basic Data Source Configuration Wizard (even if I close SQL Server). If I reboot and open Visual Basic first, I can then connect using the Visual Basic Data Source Configuration Wizard. But then I can not switch to SQL Server and open the database (even if I close Visual Basic). Again, I must reboot to open the database in SQL Server.I suspect there is a setting somewhere that needs to be changed, but I can not find it?
View 6 RepliesHowever I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).

In my VB.net code i have:
cmd.CommandText = "SELECT * FROM [strfg].[dbo].[Myfunc] (@MyParam)"
Dim myparam As New SqlParameter("@MyParam", a)
cmd.Parameters.Add(myparam)
The function (runnig on SQL server) returns a table with four columns, one row.How do I call this function from Visual Basic? cmd.ExecuteScalar() is obviously not correct. In c++ I use a recordset. What is the equivalent in vb? Does anyone have a short example?
Iam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.
