VS 2005 Data In Textbox Which Connect To Database?
Aug 21, 2011
currently i am create windows application form for staff registration for my assignment, this form is contain textbox which are connected to database.Every time i run this form ,i can see data in the textbox ,which is from column in my table database.My question is how i can make the textbox is blank every time i run my staff registration form.I dont want that data which i save in database is been seen because this form is use to add new data in database.i am using visual studio 2005 and sql 2005.Here i attach some picture when i run my form application, there is data in every textbox.
i used this code (below) but it have error on this line "dAdapter2.Fill(dSet2, "BPC_EMPLOYEE")"
Dim ConnectionString As String = "Server=bpc-k2;Database=FIXED ASSET DISPOSAL;Integrated Security=SSPI" Dim mySQLConn As New SqlConnection(ConnectionString) mySQLConn.Open()
every time i try to establish a data connection between vb 2010 and sql 2005 i get the following error message QuoteA network-related or instance specific error occurred while establishing a connection to SQL server.the server was not found or was not accessible .verify that the instance name is correct and that SQL server is configured to allow remote connection .(Provider:SQL network interface,error:26
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 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
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:
One of my testers is testing my program that imports an XML file and puts all the data into correct fields in an Access database. He said on his Vista laptop he got an error saying: "Microsoft.jet.OLEDB.4.0 provider is not registered on local machine"
I know you don't have to have Access installed to run my program and I'm pretty sure all the OLEDB objects are in the .NET framework so why is it saying that?
