I am using this to copy tables in an Access database(2003). the questions I have are:
1. How can I make this more 'obejct oriented'?
2. How can I copy just the structure of the tables and not the data?
(Currently both are occuring)
i am trying to create an vb.net program to transfer or copy tables from my access database to an MSSQL DB.I got it working to copy from MSSQL to access but not the other way around.

View 1 RepliesI want to gather some data from some tables of an Access Database, I've found some solutions online, but I haven't found ways to fill a datatable, or dataset, and get each single field properly. Is it easier for me to get whole tables then get just the info that i want, or should I make a lot of searches in the access DB getting just what I want each time? Any code snippets for it? The Access Database is in an ACCDB file, with no user or password. I'm currently using VB.NET, but it doesn't matter if you answer in C#. [URL]
View 2 Replieshow to display data coming from different tables in access in a form?...the case is this:
3 tables in access:
AddBook(tablename) - ISBN(primary key), Book_Title, Author
Student(tablename) - Student_ID(primary key), Student_Name, Course, Year
Transact(tablename) - Transaction_No(primary key), ISBN(foreign key), Student_ID(foreign), Date_Borrowed
i think you can already picture it out... so what i want is to display data from Transact table and also display the data from Student and AddBook table base on the value of the foreign keys in Transact table....

I have written lots of code with the ADO Library in VB Excel and previous versions of Visual Basic. With the dissappearance of the recordset object, how do we perform data manipulation with an attached Access Database? It seems things could be a lot easier, and less complicated by now, however, the best methods appear to currently remain ellusive.

View 5 RepliesI'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).

I have a form with 5 fields(inputs). When I entered data in the form and click submit, the data is entered into an Access 2007 Database(Table). All the set up (connection) is working because the data table is getting populated with the user info. However, I also need to search the database by entering a name in the name text box and clicking a button.
This is suppose to populated all the fields with information from the data base if the user exist. The search part is not working. I have no more hair to pull. :) Here is the code:

I do no know how to go about doing this. I have a view in the db. I have gatheredall the data in that view. Now when clicks a button, i want to transfer half column data in the view to header_table and the other half into the lines_table. Also once it is transgered, I want to display it in a grid view. This time all the fields from header_table and all from lines_lines. Can someone guide me how will I do that by an example of code that is not very complecated and does what I want to do?

How to manage multiple tables with the same structure. However, due to the craptastical nature of VB, the solution doesn't really work. It specifically doesn't work because VB.NET requires the implementation of each method/property in the interface to be explicitly declared.
As for the problem that I'm really trying to solve, here it is:
I have many lookup/domain tables in the database that all have the same structure.
The items in these tables are typically used for drop downs in the interface.
I would like to avoid a bunch of boilerplate repository methods to retrieve the contents of these tables (one method per table really sucks when you have 40 tables).
I am not using the One True Lookup Table anti-pattern and this is not an option.
is there any code to copy and rename data within the sql server.actually i reated a database which will be like default template and ever company will have the similar database with different name.So what i want when a new company is created, a copy of default database will be created with new name.

View 11 RepliesI am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.

SQLconnect As New SQLite.SQLiteConnection()

View 1 RepliesI have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.

View 1 RepliesI want to copy files with a specific extension (for example .config or .exe). It should create a structure of nested directories, and then insert each file into a specified place in the directory hierarchy. Ideally I would just specify a parent directory for each file and a parent directory for each directory and it would build it.
I need any existing utility or batch file or power-shell script or C#/VB .Net code to perform this activity.
I'm currently working on my VB.NET certification and I'm using Murach's Visual Basic 2008 for my class textbook. Chapter 16 of the text covers writing my own ADO.NET data access codes. The code I have included here is for two classes of the project:
frmAddModifyCustomerDB.vb is prewritten by murach for this assignment and CustomerDB.vb is included written in the book as my assignment to build but not prewritten for me in the solution. According to the assignment, frmAddModifyCustomerDB.vb should not be modified unless instructed by the book. The procedure in question is Private Sub btnAccept_Click on the line that reads: "If Not CustomerDB.UpdateCustomer(customer, newCustomer) Then".After copying the CustomerDB.vb class directly from the book the assignment stated that the database should update properly when using the UpdateCustomer function that is fired when the Accept button is clicked. Every time I tried to modify a customer when doing this I kept getting the Database Error message box and the changes would be canceled.
After playing with the code I changed the "If Not CustomerDB.UpdateCustomer(customer, newCustomer) Then" to check against the boolean return from CustomerDB.vb by inserting "= False". When the modified code reads "If Not CustomerDB.UpdateCustomer(customer,
newCustomer) = False Then" the application updates properly and does not fire any exceptions. I'm confused by this because the book specified that I should not need to modify the code for the Add/Modify form in order for this to work.

Public addCustomer As Boolean
