DB/Reporting :: Create Access Database (VB 2008 Express Edition) OledBcommand
Jun 20, 2009
I want to create a table (called "Customers") in a Microsoft Access database and then insert/delete records into the table and update the table. The table shall have 3 columns:
ID
Customer Name
Customer Address
I know i need to make the "ID" column as an autonumber and a primary key, as i need to insert and delete records and update the table. I am using the Visual basic 2008 Express edition and quite familar with the OledBcommand.

Microsoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.

I would like to access to a SQL Server Database from my Visual Studio project.
I have SQL Server 2005 Express Edition installed on my PC and I have a database with some tables.
In Visual Studio, I open the Database Explorer and I try to create a database connection.
The Add connection dialog box proposes to enter a database *file name* but I cannot select a database *server* and a database *name*.
Perhaps, is it a restriction because it is a free version ?
Within Visual Web Developer 2008 Express Edition, I can select a database *server* and a database *name* !

I am not able to add records in an Access 2007 database using VB 2010 Express Edition. I have read other posts and followed them but still I am not sucessful. I have the connection to the access database as MS Access Database, therefore it has the OLEDB connection (not the Jet 4.0). I am using the project instance in binding the text boxes to the fieldnames in the Access database. Did I miss something? I am also using Windows Vista Ultimate.
Below is the code.

I'm creating an application and I want to pass on a string value from one form to the other.Is there an access modifier in VB 2008 EE that would allow me to do that?Example: I have a name such as Mike in one form, in a list box, and Mike has a file attached to it with different information.I then click on a button to load another form, where the name Mike will be passed on and will be used by my program to find the file and display all the information in the file of his name.

My intention is to load my data from access database through datagridview but it keeps telling me the same error. This is the exact error message I've gotten.. it threw an oledb Exception stating: Could not open table 'MSysAccounts' in the workgroup information file. I've been browsing and viewing different resources but I still do not find a solution to view my data in datagridview. Few things I've tried:
1. I originally uses Ms Access 2007 to load, but it does not seem to work well, hence i converted it into Ms Access 2003 format. Same error displayed.
2. Working around with the workgroup in Access 2003, creating new workgroup which creates System.mdw file and I replaced it in:

I downloaded the free Visual Basic Express Edition to create an application that connects to a Mysql database. I searched for the connection string and found a bunch of different ones.I have no idea which one should I use with Visual Basic Express Edition. I have been using PHP, javascript and mysql for a couple of years, but I have never used Visual Basic and have everything to learn.

i am creating a quiz which would be 20 questions for software design students and may use alot of code.my first problem is the score for the test, i know a friend of mine can add up the score but he cant move onto the next thread until you have got the question correct which is sort of cheating, i want to know how you create a variable and make that variable stay in all the forms and add up the score of correct and incorrect answers and come up with a final score for the user in the end.

1.Establishing a connection to a database(preferably one that is inherit within the project and can travel with it)
2. Setting the correct references to the database ( I tried connecting via JET with windows 7 and I get an error that I cannot use JET)
3. Query the database (Access) with SQL, and return those results to a recordset.
4. Loop through the recordset.
5. close the database connection
6. Open recordset and write data to table.

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 am trying to create a simple countdown timer using vb 2005 express edition. I think the code is fairly simple but I have fallen at the first hurdle. How do you display the result, i.e. which control do you use? Tried label and textbox but both return the error: "Value of type [integer or long] cannot be converted to [textbox or label].

I have a program that I need to import a csv file into sql database/tables.I am using Visual Basic 2008 express and sql server. When complete I have to distribute this to several users where they will have csv files in the same format but with unique data.It has been several years since I have done any programming and then it was vb6.I have quickly realized that my vb6 books are going to do me no good. I have spent an entire day watching tutorial and reading forums to no use.
The csv file is full of junk, where some of the records are 92 fields and some are 122. The fields have data that may have dozens of characters before and/or after the data that I need. On the good side I was able to pull the file into access and load it into two tables by using something along the lines of (where this = this, fill this table and the same for the second table.) So I have my 92 char records in one file and the 122 in another.Unfortunately though I can not use access to do this as many of the users do not have it. But by doing this I was able to work with the data in the file to get all of the fields set for name, length, type ect.So then I went into my vb project and created the database with two files.I set the fields up according to the information I got from the access tables. So I know that these two tables are a perfect fit for the data in this file.
What I need to be able to do is have the user browse through the program to find the csv file they will be using. If they have followed my directions, they should have placed it in the same folder as they program I will send them.I then need the program to take that file and import the data into my sql database/tables.I have come to the conclusion, given the condition of this file, that rather than try and clean it up before using it, it will make more sense to just get it loaded into the two tables.Then have my forms ect go and get the information that they need from the tables. Then after we are done using the records save them to a clean tables.

My company currently has vb.net 2003. I am tasked with evaluating vb.net 2008. And suggest if upgrading to 2008 edition is necessary or if it will be beneficial. For this purpose I decided to experiment with vb.net 2008 express. I have some questions regarding this.
1) Will vb.net 2008 express edition will give me idea about new features etc. ?
2) If I install vb.net 2008 express edition on machine which has vb.net 2003, will it cause any problems to vb.net 2003 ?
3) If I code in vb.net 2008 express edition, on upgrading will this same code work ?
