I have an access project. I'm trying to figure out the proper way of using an ADODB.Recordset to control data in a subform. For example, I want the user to be able to make additions, deletions, and updates to a subform datasheet. However, if the user presses "CANCEL" from the main form, then I want the data to be replaced with the old data. Likewise, if the user presses "Save" from the main form, then I want to update the database at that time only. The only way i know to do this will update the database after every row is updated. Can I not use CancelBatch and UpdateBacth?
I have an Access 2007 (w/ Vista O/S) project where I use an unbound form, to populate the form I use a DAO recordset to pull the data from the backend table. I want to have the ability to load a project and return the attachments that are only for that particular record. Subsequently, I need to be able to save any attachments to that project record when the 'Save' button is clicked (the files to be saved to the record are user-defined, and therefore not in a particular/ constant folder).
I would like to avoid using OLE objects and streams if possible, but not sure if that's doable. I know how to navigate to the given record, but how do I return the attachments? Also, I've read this article [URL] and a bunch more, including other MSDN articles [URL] and their related links and still not sure how to achieve the desired end result. I've also tried changing the attachment object's (located on the unbound form) controlsource, but to no success.

I am developing an application on VB2008 with MySql as database. I opened the connection without any errors. I have three fields/columns in my database and on the form. When I am running vb form data is not reflecting on to form fields.
I have written the following code in form load event. 'Dim cn As ADODB.Connection 'Dim rs As New ADODB.Recordset 'cn = New ADODB.Connection 'cn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=in_out;" + "UID=root;" + "PASSWORD=pacvision;" + "OPTION=3;" 'cn.Open() 'MessageBox.Show("Connection Opened Successfully") 'rs.Open("Select * from deptno", cn.ConnectionString, ADODB.CursorTypeEnum.adOpenKeyset, ADODB.LockTypeEnum.adLockOptimistic)
First form has 1 listbox and 2 buttons. Second form has 1 datagridview and 1 button. The first form opens the csv and list the location+filename of the CSV file. When the CSV files are listed in the listbox, the user can edit the selected csv file in listbox through edit button, when edit button is pressed, the second form will show as dialog and automatically opens the CSV files in DataGridView. The user will edit some fields and save and the second form will autoclose. Now here's the problem, when i select another CSV file in the listbox and press the edit button, the previous CSV still shows, even other CSV files I select, still the previous CSV file was showing.

I used to work in VB.net and used Dataset's all the time when working with ADO, but now i'm Working in C# and the Research is showing me a lot of Recordsets.

I have an application in VB6 that joins 3 tables together to create 1 record set and I am able to use the move next and move previous methods to navigate through the record set.
I am having trouble creating this same scenario in vb.net with a data set. Do I have to create each table individually and then link them together somehow or can I join them all together in a query before I fill the data set?
I have a continious Form which opens and shows records of people with whatever criteria the user had chosen the screen before. When the form opens it checks which button was pressed and then changes the recordsource of the continious form.
When I try to edit the records it says "Recordset not updateable". I have done everything I can think of, I have change the type of recordset from dbopensnapshot to dbopendynaset.

I'm working on a project where I've loaded a database into a DGV. I also have an additional unbound checkbox column for the users to select entries with. I have code in place to read the selected rows and save them into a CSV string, which is then saved in the usersettings. All this works fine.
PROBLEM AREA: I'm trying to reverse this effect so that when the DGV loads, the checkboxes that the user selected previously are checked (and the others left unchecked). I've debugged this extensively, and using watches have confirmed that all the values in the loops are right, and the conditionals are all kicking correctly, but it seems the code I'm using to actually check the boxes doesn't work. I've searched dozens of web pages, msdn white papers, and forums, but no suggestions will check the darned box. Below is some example code.[CODE...]
In debugging, it seems the value for the Cells IS changed, but the checkbox never gets selected. The try/catch was just to pick any error messages (but there are none with this code). What am I doing wrong here?
I am trying to display unbound data in a DataGridView.I set up columns already design-time. I am at a loss for creating code that adds a new row using the column schema that was created in the Designer?Something like this?
dim newrow as DataGridViewRownewrow.cells.item("name").value = "text here"datagridview1.rows.add(newrow)
I get an error saying the 'name' column was not found?
I just want to know the right practice for database application. as of now i am creating a simple database application where the database is all bound to the control for minimal coding purpose. is it a good practice?
I have a form created which an unbound datagridview that has three columns. "Position", "ID", "Name". The data is being added at runtime into a database upon the forms completion. (I don't want to add unnecessary rows to the database in the event a person clicks Cancel.) What I need to do is on the deletion of a row in the datagridview, search through the rows "Position" for a "HJ" value. If it's not found, change the "Position" value of the first row to be "HJ".
In this project that I'm creating, I'm creating a mock-up of a page that uses a DetailView (something I saw in a blog) that seems to fit my needs. However, I don't want the data to be bound to anything.So, I added the control and then I started adding the appropriate mock-up columns to it and tried to render the control on the test page. Where the HTML that ASP.NET should generate is nothing.Here's my code (there's a 'real' DetailsView control, then a button and then a blank testing Details view control):
I have a datagridview.. It is unbound to any database and has 2 columns..1 is item name and other is amount/expense, incurred..I want the total of expense incurred be displayed in the textbox on button click ie adding the numbers in amount column..
