I am usinf VB 2005 Express and I an trying to connect to a SQL Server 2005 Express Database using the "Add New Data Source"I keep gettig the following error.Unable to open physical file "C:Program FilesMicrosoft SQL Server MSSQL.1MSSQLDataHeartland.mdf. Operating system erro 32: "32(The process cannot access the file because it is being used by anither process.)"An attempt to attach an auto-named database for the file C:Program FilesMicrosoft SQL Server MSSQL.1MSSQLDataHeartland.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
I need to connect to an MySQL database in my VB.NET application (VB 2010 Express). When I attempt to use the Data Sources wizard to establish the connection, it does not provide an ODBC data source. I'm using Add New Data Source/Database/DataSet/New Connection which shows the Add Connection dialog. The only options it gives me for data sources are Access & SQL Server and the OLEDB data provider. It does not appear to give me the option of adding a new data source provider. Attached is an image of my current Change Data Source dialog. Where do I get the ODBC data source provider and how do I install it into Visual Studio?
Is this software what i need to install to extract data from PDF documents using 2005? If so is this the link i need to get it from? [url] I just got no idea about itextsharp
Only my local dataset updates when adding, deleting or editing records.The Source Database is supposed to update on issuing DataAdapter. Update(dataset )However, when I check my source database after running the operations it remains the same as the original.
I have a VB 2005 WinForms Project which is giving what I think is a false error.On the Designer screen for the main form (which normally displays the form layout etc.) I get:One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.'. ctor' is not a valid identifier.
am working on a project and am using sql server 2005 express as my database server, the problem is i can;t connect to the sql server from any machine on my local network (windows).
I am trying to uninstall VB express 2005 but keep getting an error that it cannot complete. I have looked but could not find a place to reinstall to see if after that it will let me then uninstall it like many have suggested but can not locate an install place. I am trying to get it removed to see if it will then let me install SQL 2008 on my computer.
currently developing the backup and restore procedure of my database....and im using the SQL UTILITY[URL]..but...i was thinking if is it possible to obtain the Data Source or the Server name automatically...when the form load.
I'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated.
The card numbers are in a combobox (which are retreived from an SQL database using the binding source which is linked to a data adapter), and each card has a boolean 'confiscated' field in the database.
It does actually set the card to confiscated after the 3 tries, however I'd like the form to 'refresh' so the card no longer appears in the combobox, without having to close down the form and reload it. Is there a way to do this? I've tried refreshing the combobox and data adapter (.Refresh) but this does nothing
I built a database from an .sql script file in Microsoft SQL Server 2008 Express Management Studio.Now, I need to connect an application I'm developing to this database. So in Visual Basic 2008 Express (that's what I use) I go to:
Data-->Add New Data Source-->Database-->New Connection In the dialog which pops up (name: Add Connection) I set: Data Source = Microsoft SQL Server Database File
I'm working on deploying a visual studio 2005 windows application executable with an embedded crystal report using visual basic. It seems to install everything just fine, however, the system dsn isn't being setup.
How do you configure a setup project to setup the system dsn during the installation?
I get the error message: "Format of initialization string does not conform to specification starting at index 0" What does this mean and how can I get the database to open in vb express 2008?
I have noob question. I made a dataset of a sql express 2005 database using the designer. So it's a typed dataset. Then I declare some tableadapters and fill them.Now I do this to add a record to my dataset:
Private Function SaveOrder(ByVal controlenummer As Integer, ByVal PK_BaanID As Integer, ByVal starttime As DateTime, ByVal stoptime As DateTime) As Integer Dim orderRow = dsIntveen.tblOrder.NewtblOrderRow orderRow.Controlenummer = controlenummer orderRow.FK_Baan = PK_BaanID
I am looking to make a data connection with a network server(sql server 2005). When I run the data source configuration wizard, it allows me only to pick a local database file. I want to use a connection string like this "Data Source=SQLSERVER;Initial Catalog=mydb;User Id=username;Password=password;" I know I can do that programmatically. But I would like to know whether I can do that using the data source wizard so that I will be able to use Bindingsources and tableadapters.
I'd like to make a program module that exports all records from three tables in a database into a file at once(I means not adding row by row, maybe like BULK). how to code for exporting and importing?
I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.
The program I am trying to modify was initially written using VB 2005 Express. I have subsequently downloaded the 2008 version. The program creates a monthly spreadsheet from a template. The old code that will no longer (highlighted and underlined) compile is as follows:
I have attempted to uninstall VB 2005 express and C++ express using Remove Add programs to no avail. Error message: The Window Installer Package c:program files visual studio 8 vs_setup.msi could not be opened. I have removed the MSDN library and SQL server successfully. I have also tried vs_uninst_betas tool which doesn't find anything to uninstall. I would prefer not to modify the registry if at all possible. If I could find a source for the original install packages for VB and C++ I would attempt reinstalling and then uninstalling....but cannot find them anywhere.
I have a VB.NET WinForms application. While adding a new data source, it is giving "An item with the same already been added" on the Add Data Source wizard form.
The application does not contains any existing data source.
What could possibly be causing this error, and how might I go about resolving it?
When trying to add a new data source (connect to database with .mdf extension stored on my computer)verything goes well until I get to he step giving me the option to save the connection string, then I get the following error message: "An unexpected error has occurred.

I am taking a course online in Advanced Visual Basic and most of it involves working with databases. If I cannot get past this error, I cannot do any of theassignments. I am using the free 90 day download of Visual Studio 2008 and will buy it before trial expires, but only if it starts working and stops generating error messages

I'm trying to add a computed column to a datatable that references another column in the datatable. Sometimes the computed column has a mathematical operation applied to it, but in this case I'm just referencing the original column. The code looks like the following:
The code isn't actually hard coded as shown above - there are functions that return the values for the first and third parameters - but I checked those and they are returning the expected values and not generating any errors themselves.
The error is thrown when the .Add method is called, and the error states "Syntax error: Missing operand after '_1' operator." It seems to me that it doesn't like the column name, which I suppose I could change and just workaround it at the presentation level. Still, I'm curious. Is this a bug in the .net framework or something? It doesn't mind "1_1" as a column name in the datatable, so why is it having a problem with it in the expression statement?
