I have records in my datagridview (from database(ms sql server 2008 r2)). What i want to do is to insert the records selected by my datagridview checkboxcolumn and IF POSSIBLE automatically delete a record if the records to be inserted are equal to the records inside the database. (Hoping you got what I want to say.) For example. I have an A,B,C(child) that is under XXX(parent) in my database and I'll be inserting the A,B(child) again but it will be under YYY(parent). The old record in XXX will be deleted except C. I just want a possible DELETE STATEMENT These are what I've done so Far :

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.

View 4 RepliesI'm in the process of making 2 database applications. Each are encountering their own set of errors. For this particular application, I have a "Main Menu" form that has a button which loads an "Add Record" form. The user is suppose to be able to insert new records here via text boxes, but the problem is that record with the first primary key is being displayed in the text boxes when the "Add Record" form loads. I have no idea and can't find anything anywhere about making these boxes blank. I'm connecting to the .accdb through a dataset.

I have been trying for a month to get a row added to an Access database and can not do it. I have the databindings all set and can select different records, but can not add a new one. I have tried BindingSource.AddNew.row() but can't figure out how to add data to the new row, nor does it show in the database.
I have tried
Dim ds As New myDataSet '<---Change this to the dataset name on your form
Dim dr As DataRow
dr = ds.Tables("Students").NewRow
[Code].....
But that doesn't do anything at all. No data added, no errors. I have tried updating a datagrid to be told it can't be updated when bound. I look on google and nothing seems to relate to adding data to an access database when bound to the project through the datasource wizard.
I have the following code which I hoped added a row to my DataGridView and also a record to my database. It does the first part, but not the second.
Dim row As DataRow = Me.CCLogDataSet.tblLog.NewRow()
row("cc_log_contract") = Me.txt_Log_Add_Contract.Text
row("cc_log_registration") = Me.mtb_Log_Add_Registration.Text.ToUpper()
row("cc_log_milage") = Me.txt_Log_Add_Milage.Text
[Code] .....
It seems to be storing the data in memory? As the data in the DataGridView is persistant, even after a Relaunch of the application. However, why I query the database, there are no records in it.
I'm trying to add a record through access. Below is my code. My problem is that when I add a new record, it adds to the database fine, and goes back to the first record like it should, but when I then scroll through using the BtnNext (button), it replaces the last record with the first record for some reason. This is the UI of it [URL]. A bit of further explanation, I'll have 3 records, IDs 1,2,3 respectively. I go to add another (with its ID as 4). When it's added, the program displays ID 1 as it should. It then goes 2 then 3, but instead of 4 as the next one, it displays 1 again. So 1231.

I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.

The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?
The apostrophe is used to separate data when adding records to an Access Database data table using the "INSERT INTO" SQL statement. Having apostrophes in the data really screws things up with this new software. Is there a simple workaround? Is it possible to specify a different character? Is it possible to add data without using SQL Statements? I also noticed that the new OleDbDataAdapter Add Method generates the same SQL Error because it apparently creates an "INSERT INTO" SQL Statement.gh
