INSERT Or Update In SQL Server 2008 R2 Express In VB 2010 Express
Jan 21, 2011
I am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.
Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
there Dream in Code Community! Im an okay programmer as far as skill right now I am still learning as we all are I need some help from some experienced VB.NET programmers in the community, Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords.

I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
I have recently developed a back end database in SQL server 2008 R2 and attached it to a application in VB express 2010.Everything works fine and when i publish the application, it works fine on my machine, but once i try to setup up the application on another machine i get the error message: A network related or instance specific error occurred while establishing a connection to SQL Server. Server was not found or not accessible please verify the instance name is correct or allow remote connections.I have read numerous forums on this saying about changing the connection string and instance name.but with being novice i dont understand what needs to be changed etc.The sql server allows remote connections, but i am unsure what else needs changing to allow the application to work with the database on another machine.
I'm using VB 2008 Express for our College Project. I'm also running SQL Server 2008 Express and have installed SQL Server Management Studio and used it to create my database. Both software have been installed and running locally. I'm trying to connect to the database from VB 2008 Express. Database connection wizard have 3 options:
connecting to Access db connecting to SQL Server 3.5 compact db and connecting to SQL Server db file.
I have SQL 2008 Express and Visual Basic 2008 Express runing on XP Professional SP2. When I select add new data source from VB I don't have the option to connect to SQL Server 2008 express to get at the to SQL Server Database. I also notice that the OLE DB connector is not availble as a data connector. Can somebody please confirm that VB 2008 Express can connect directly to SQL Server 2008 Express and how I can achieve it.
'm trying to use Visual Basic 2008 Express and connect to a DB of SQL Server 2008 Express but ... you can tell me why in the Database Explorer and the Data menu of VB only have the following options for data source? Microsoft Access Database File Microsoft SQL Server Compact 3.5 Microsoft SQL Server Database File does not have the options Microsoft ODBC Data Source Microsoft SQL Server obs.: I have the Visual Web Express 2008 installed, and there are the options available.
Is it possible to connect to a database on SQL Server R2 Express from Visual Basic Express? I am following a set of tutorial videos done in SQL Server 2005, but cannot seem to connect to create the database. I have created the database in SQL Server R2 Express, but cannot connect. Is there a work around?
It's probably just a case of me not looking in the right place or not seeing the obvious, but does anyone know if a machine with just version 2.0 of the .NET Framework should be able to run a VB.NET Express application which accesses a SQL Server Express database file? Or is there an additional requirement for a non-development machine to have some kind of SQL Server Express runtime component in addition to the 2.0 Framework?It seems to be counterintuitive to expect that a VB.NET application would be able to access any kind of SQL Server data without having some kind of SQL Server host component (Express or otherwise) installed. But then again, it seems just as counterintuitive that Microsoft would require the download and installation of the new framework as well as a separate database runtime in order for the average user to run an application with accesses a local SQL Server Express database.To me, it runs contrary to the whole concept of XCopy deployment to require more than just the application's files and .NET Framework for an application to run properly. But nothing I've read so far explicitly indicates that a user would require anything more than the app files and the framework to run an application which accesses SQL Server Express data. But...I can't get any VB Express applications which uses a SQL Server Express databases to run on any machine that doesn't have SQL Server Express installed.What am I missing?(Apologies if this isn't the right group to post this in.
Is VB Express 2010 slower to compile and run that older versions of VB Express? I've installed it this weekend and it seems a little sluggish on my quad core computer with 1 gig of RAM. I have VB Express 2005 installed for my students at school and it seems to fly just fine. Those school computers are older P4s with 512k of RAM.
I have been working on a simple delete and update thrugh the TableAdapter in Express 2010 and can't get it to update after a delete query. The same TableAdapter works fine when I do an 'Add', but not after the delete. What am I missing? I could use the SQL commands, but would like to use the software commands instead. Here is the delete code:
I am using VB 2008 and have a datetime picker. I wam trying to use this value in an INSERT command to load in to a table but I just can't get it to work. I debug it out which shows something along the lines of "24/03/2010" but it just won't accept it. However, if I create a string variable e.g. strDate = "24/03/2010". it works. I am obviously doing something wrong in the conversion.
I try to use my data source and setup a new connection, but i see it wont let me.Is this another features they left out of 2010 express edtions?I just want to setup a connection to sql server with vb.net express 2010?
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 want to use a connetction string for connect a databse in sql server express by vb.net? My code is : Cn1.ConnectionString ="Data Source=.SQLEXPRESS;Integrated Security=True;Connect Timeout=30;User Instance=True" but i when open then connection i see this error Cannot open user default database. Login failed. Login failed for user 'Shahab-PCShahab'.
I am doing a system for my project. The system will request user choose or fill-in the birthday date. From the birthday date, I need to calculate the age and store it into database (MSSQL). My problem is, if I am able to calculate the age and store it into database, how do I update the age? How do I update all the age in the AGE column every year? (no matter update based on YEAR or MONTH DATE as long as there is a way to do it, automatically)
I've used MS Visual Basic 2010 Express to build a very simple VB.Net Windows app. I need to check the code into our Team Foundation Server Source Control. Is there a TFS plug-in for VB Express? If not, do I need to check the code in manually?
I'm quite new into the programming game, I've been working on this program for a few weeks now, and its coming along, but the method I searched for entering new rows of data into my table doesn't seem to update my tables after I try entering data. I have a feeling it may be something very simple that i am over looking.

I have version VisualBasic.2010 Express Edition , but this version Does not have the choose Microsoft SQL Server (SqlClient) when open vb.net choose : add new data source and choose database and add connection Does not have the choose Microsoft SQL Server (SqlClient)
Visual Basic 2010 Express, lets the user to add a Local Database with .sdf extension. These databases needs MICROSOFT SQL Server to be created or they can run in the user's pc without any additional software? What are the limit of these databases unlike an external database?
Initially my app worked with excel fine, now it causes my computer to reboot only after Excel has been opened (two or more times). I have opened and closed Excel files 20+ times without running thru either of my apps (they all uses identical code for excel) and it has never caused a reboot or a crash.
run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer. Adding to that I then have to do a manual shutdown because the reboot process after is unstable. (System doesn't respond properly). My code in this app is small, should make for a good example. I can provide the entire project to anyone who would volunteer to test it. (First I need to know how to send the project).
The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well
how I can implement my calendar with VB .net express 2008 and MSSQL 2008 Express. How do I get it to work with datasets, binding source etc.If I go to Properties>settings my connection string is:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|CalendarDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
and I have a table with fields:-
CalendarID Subject Location Purpose
[code]....
I can Add the event to the calendar I have the necessary items on my form linked to my table and I can save them to my table:
