I have a nvarchar(256) field in a SQL 2005 database table that contains several records in Chinese and I'd like to output this characters correctly in VB.NET code.What I have now doesn't work at all:
Dim MyText As String =
Dim value As [String] = MyText
Dim tc As Encoding = Encoding.GetEncoding(950)
[code].....
i have search for the whole forum and google but found no trace on converting from a ascii chinese character to unicode chinese character in .net control
View 2 RepliesI have a login form. all my code is valid with the database and all that.i use an if statement, like if passoword and username match database password and user name then it allows them in then opens my main form. code for that is as follows
[code]...
for some reason, it shows the correct messageboxes and correctly validates all through database, but it closes the Login form correctly, but then shows the main form only for a second, then closes program. I am having issues with similar form opening and closing in other parts of the project as well.
Recently, I handover the project which includes Chinese Characters on Form.But in my PC, these characters are display as "Square".So, can I know which font file I'm missing by checking the project contents file??And if I deploy with a set up exe to user, will this font file pack together? or i should manually insert this font in user PC?
View 8 RepliesI want to search a sql server database from VB.Net and output the results in a Listview. I don't want to use code that involes queries in it, but the queries are to be used in the data set designer, i.e the query builder.Here's what I got so far.
I created a query in the builder called SearchStudent
SELECT FirstName, Surname, Email, PredictedGrade, Notes
FROM tblStudent
WHERE (FirstName LIKE @FirstName) OR
(Surname LIKE @Surname)
Here's the code to search the database and fill the dataset

I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?
Ive created one database Sql Server Compact Edition 2005, with one table ("Cliente") I know that I can created my database good, but i have a problem saving information since three textbox, in my table(With columns "Nombre" "Apellido" "Cliente". In my form there is a button save ("Guardar"). When I do click in my button appear the next message : "The column cannot contain null values. [ Column name = Nombre,Table name = Cliente ] " and happen the same with apellido and Id_Cliente. And this happen becouse my code cant save the information....
This is the code
Option Explicit On
Option Strict On
Imports System
Imports System.IO
Imports System.Data

And the code for my button is:
Private Sub cmdguardar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdguardar.Click

before re-inventing the wheel, i want to ask you how i can do this best: I have a VB.Net application that uses a database connection to MS SQL Server 2005 (express version). There are users that input data with the application into the database lets say once to 2x an hour to once a minute. I want to do backups like this: Once a day or once a week (in the evening) a full backup, and whenever the program/user is idle for lets say 10 Minutes, i want to do an incremental backup (so that it does not take so long until he can work on after the backup).
There are no big security issues, just copying the backup data files to a network share / a different computer or server would be fine. i guess the average db size may be 300MB, but the daily increments about 1MB.

I had made a project in VB.NET 2005 with SQL SERVER 2005 used as database. Now i want to make a setup of this project but i am unable to integrate sqldatabase and .net framework in this setup project. Is there any way to do this. Because it is assumed that the client does not have .NET Framework installed nor he has SQL Server on his system and the worst condition would be he does not have even internet connection from where these two setups can be downloaded if we give the condition for downloading these programs from the net if the client does not have these programs installed on his machine.
View 2 RepliesI am using a database file Database1.mdf which have a tabel called student. This Database1.mdf is simply added by using the option Add New Item in Solution Explorer. The problem is that I am to able to update the database through form and code. The code is as:
Dim conn As SqlClient.SqlConnection
Dim ada As SqlClient.SqlDataAdapter
Dim cp As SqlClient.SqlCommandBuilder
[code]....
The ds is updated at run time, but as form is closed and run again the actual database table student is not updated.I have no idea what is going on. The same code work right with Access database and SQL database but in this case it is not working. I've tried on google but not getting satisfactory answer. I've also seen a post on this site but that is about ConnectionString, not about the database update.
'm just a beginner who want to learn on manipulating SQL Server data using vb.net. I have already experienced manipulating data in ms access. So I just recycled the code that I used in here.

I'm trying to connect to a sql server 2005 database. I'm using the following connection string.
Dim cnn As OleDbConnection = _
New OleDbConnection("Provider=sqloledb;Integrated Security=SSPI;Initial Catalog=Iconics")
Using this connection gives me the following error :
Error : Microsoft OLE DB PROVIDER FOR SQL SERVER : [DBNETLIB][Connection open(connect()).]SQL Server does not exist or access denied.
Does anybody know what is wrong with this connection string.
I have just downloaded SQL Server 2005 express edition from here:To be used as a database for a vb.net program. But I'm confused in using sql server. I do not know where to start from here:If not, where could I create the ms sql database? I'm a beginner and I want to learn.
View 1 RepliesI can connect to both databases with SQL Server Enterprise Manager, so I know the servers are up and available. One of them is SQL1, the other is SQLTEST.In my program when I use the following connection string, it work connects just fine:
conn = New DBConnect("Data Source=SQL1;Initial Catalog=SignInspection;Integrated Security=SSPI")
However, if I change SQL1 to SQLTEST the connection times out I don't get any errors other than the timeout error.I can run the profiler on SQLTest and see that it is most definitely NOT even attempting to connect.
EDIT:Well, it's a moot point now because I got authentication working properly on our SQL1 server.
First off, the web server is running IIS and .NET. Users are logged in to the intranet using Active Directory, and the .NET page needs to retrieve their log-in credentials (username most notably). The database is SQL Server 2005, running on a different machine. But the .NET app needs to impersonate as another user to connect to the database.
To successfully do both of these things go to Windows > Run, enter inetmgr and hit run. Navigate to the site and right click > properties, then click on the tab titled Directory Security, click Edit.., make sure only Integrated Windows Authentication and Digest authentication are enabled. Enter your proper AD realm and click OK. Apply the settings/hit OK.In web.config you need the following lines
<authentication mode="Windows" />
<identity impersonate="true" username="myDomainMyUserName" password="123mypasswordgoeshere">
replacing, of course, myDomainMyUserName and 123mypasswordgoeshere with the username and password that has login rights on both your domain and your sql server. The connection string can probably be modified, but this is mine and it works:
Server=SQL1;Database=SignInspection;Trusted_connection=True;

I am using Visual Studio 2010. I want to do database connectivity using VB.Net and MS SQL Server 2005. I know 1 way of doing this. Following are the steps...
1. Create a new Data Source Using Data Sources Window.
2. Select the appropriate view like details view/ data grid view for that data source
3. Drag that data source on your form and connectivity is done. Also all the controls are created by the visual studio.
This feature is really cool but I want to learn database connectivity by pure coding without using such advanced features. Also is it possible to do connectivity from a class library ?
I normally place all db related work in my databases in SQL Server Express 2005. But in tutorials I have seen, I heard that one needs to re-create referential integrity and relationships and constraints and checks and defaults anew in datasources mapped onto databases. Is this true? What parts of a database are NOT mapped on to datasources?

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.
