I am attaching DBs using following code.
Dim conn As New SqlConnection("Server=MyHomeServerSQLExpress;Database=master;Integrated Security=SSPI")
Dim cmd As New SqlCommand("", conn)
cmd.CommandText = "CREATE DATABASE dbNoPWD ON ( FILENAME = 'd:dbNoPWD.mdf' ), ( FILENAME = 'd:dbNoPWD_log.ldf' ) FOR ATTACH"
conn.Open()
cmd.ExecuteNonQuery()
cmd.Dispose()
conn.Dispose()
I do not want to give any username and password. When I ran the above code and then checked SSMS, I found my attach DB was not checked in Roles (pls. see pic.) The problem with this is my network computers can not access this DB. I want to run some code like above (without sa password) and want that all my network computers can access the DB without my user get involved in setting up SSMS.
I already made a .VB project using MVS 2010,I'm new in attaching database to SQL server and I'm confused attaching which database I'm going to attach because in the same folder i found that there's two
if user needs to attach the databases to the instance of server manually before being able to use the application?I have added the mdf file to my Setup project. It installs and copies the file to application folder. I donot know if the file needs to be attached or there is a way that application could do it automatically (attach to MyComputerSQLExpress)
attaching filesI am using VB2005 and MS access as a database.I have created a project where a user can add a new record and sometimes with adding the new record you also need to add backup, example a picture,excel, word, txt,pdf.I need to know how to do this?It can be save either on a folder on a local drive or database.I would like to be able to select a file and save it, and if
Just after installing my application, I need to attach my DB to SQL server. I am using following code for it.
Dim cmd As New SqlCommand() Dim vrMyConString As String = "Data Source=.SQLExpress; INITIAL CATALOG=master; uid=sa; pwd=sa;" Dim conn As System.Data.SqlClient.SqlConnection = New SqlConnection(vrMyConString) cmd.CommandText = "sp_attach_db 'e:dbTest.mdf', 'e:dbTest.ldf'" ' conn.ConnectionString = "Data Source=.SQLExpress; INITIAL CATALOG=master; uid=sa; pwd=sa;" conn.Open()

It returns an error:"Login failed for user 'sa'. The user is not associated with a trusted SQL Server connection."

I am using the following VB code to attach my DBs to server.
Dim cnnConnection As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=" & Application.StartupPath + "datafiles" + TextBox1.Text + ".mdf" & ";Integrated Security=True;Database='" & TextBox1.Text & "';Connect Timeout=30") cnnConnection.Open()
But it gives an error:
Unable to open the physical file "D:.Net ProgramsSQLDBAttachExperimentsSQLDBAttachExperimentsinDebugdatafilesdbSQLtest.mdf". Operating system error 5: "5(error not found)". Cannot attach the file 'D:.Net ProgramsSQLDBAttachExperimentsSQLDBAttachExperimentsinDebugdatafilesdbSQLtest.mdf' as database 'dbSQLtest'.
Right now, inside the access file, the mssql tables are set up as linked tables so queries can be written using tables from both databases. (e.g. "select * db1.table1 where db1.table1.somevalue not in db2.table1", or select into tables like that one)These queries need to be moved into a VB.NET project, but still be linked to the access file.ng loops or something?
I am looking to define data types by fields in SQL Server 2005. My source is an Excel spreadsheet and I cannot define by columns because each row requires a set of definitions applied to each field in that row. Ex, row 1 requires field1 to be CHAR while in row 2 field 1 needs to be DATE.
I have recently been working on a number of sections of code that deal with the insertion of Nullable types into a database. As I'm sure anyone who has dealt with similar code will be aware of the annoyance of constantly writing conditional logic to deal with the insertion of nulls into a database. I.e.: MyValue.HasValue ? MyValue.Value : DBNull.Value; If(MyValue.HasValue, MyValue.Value, DBNull.Value) Basically I am just wondering why DBNull.Value exists and why Null simply couldn't be used?
I have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.
I have created my site using ASP.NET Personal Starter Kits 3.5. I use Visual Studio 2008 only . .with its built-in SQL Server (2005 Express) ... my database in App_Data is ASPNETDB.MDF ...I have created some of my tables also ....in ASPNETDB ..In my local PC the site was running fine ...But when I publish my site on production server it doesn't work and shows the following error
I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.
How can I write a connection string? I has four different computer that can be connect via ethernet.How can I maintain a inserting data if to computer insert on same table at a single time..??

I am developing a desktop application in VB.NET 2005. I have a requirement whereby a user need to select a .txt file from his machine (client) and after clicking the save button, i need this file to be saved in the server into a specific folder. Similarly, i should be able to retrieve the file as well.
I am using following code to attach my database to SQL Server. The problem is if I create a new file and attach it through my code but when I detach the file using SSMS and again run the same code, it gives error. [code] All the permissions are the same even first time.Also what should be the connection string if I need to use DB with uid sa and pwd abc123?
I don't know if I am asking the question correctly, but I want to keep a program I use all the time in memory (running).So instead of closing the program (main form), I would like to simply set it's visible =false. This is easily done and works.Then on restart (I already know how to check to see if it is running) I would like to attach to it and make that running version's main form be visible again.

I've written a simple program for viewing images. My issue is how someone would view these images If I deployed my project to a client. To display the images, I have an Access 2007 database with the full path written for each and the program reads the full path into the Picturebox.ImageLocation property. I've also stored the full, root, and relative paths in the database as separate fields. My issue is how to add these pictures to my project. and which project to add them to.
Do I add them to the main project with my forms?Do I add them to the installer/setup-wizard Project?Should I all the files individually or as a compressed .zip file? Additionally, I don't know how to point to these files once they're installed on a different machine/network. Do I write a different root path to the database when the program is installed somehow?
say I have a library, in which I added a few Console.WriteLine(..) statements tot during the implementation and see w going on when I use the library in a Console AppNow I want to use the same library in an ASP.NET app. Ideally I would be able to log on to the production webserver, and somehow start a command prompt and attach it to the website and see the messages in real time as they occur. How do I do that?
I want the program I am making to show the cursors position on the process it is attached to. Sorry if this is a lot to ask for. Can you tell me how to.
1. Make a drop down menu with the list of process.
2. When i click on one of the processes, my program attaches to it.
3. When I move the cursor over the process, my program tells me the co-ordinates of the mouse on the process.
4. When i press F3, Timer3 Starts.
5. Make the mouse move to a co-ordinate on this process.
If it is too much to ask for, can you just tell me how to do 1 of them and hopefully someone else will tell me to do the others.
