Updating dataadapter access - Chatopolius

which brings me to the problem of it being inserted, everytime it runs it just appends all the records to the bottom The rows in "DTable" decide what happens with the corresponding row in the database.

In this case I added, deleted, and modified a list of books wrote on a paper.

I am doing all these steps at the same time, but when I try to update my database, it is not happening. When the click event on the button save happens, I do this. Update(Data Table) and I know that I am missing something. Try this with your Data Table and Data Adapter: (untested) Dim changes As Data Table Try Dim cmdbuilder As Ole Db Command Builder = New Ole Db Command Builder(Data Adapter) cmdbuilder. Update(Data Table) ' use your update statement or the following two statements changes = Data Table. In this case I added, deleted, and modified a list of books wrote on a paper.

I am needing to update a database Access2007, with a Data Table where I have done Adding Rows, Modifying Rows, and Deleting rows. How can I update my database from a Data Table, using 2010 and a database Access 2007? I know update the data Table, but when I try to update the Data Base, I know that I am missing something. Update(Data Table)." id="ctl00_m_m_i_ctl00_gr_ctl07_bestanswerbody" class="textarea-bestanswerhidden" name="bestanswerbody" answerbody Id="5367784" / You have to add commandbuilder to your code. But each thing will happen, before the data is stored in the database. We have a list of books wrote on the paper, and we want to add a couple of books more, but later we discovered that one book is not needed, and 2 seconds later, we see that the name of a book, is wrong, spell mistakes.

Fill (table from MS Access) and when I updated the sql Data Adapter with that table nothing happened.

so I pragmatically built a new Data Table from that Data Table and updated.

Tables("Assignments") I read this artcle on msdn - but it did not seem to help much, I am confused but I believe my problem is not identifying and passing the correct dataset back into the database.

This works, BUT every time it runs its just appends the data to the end of the database and doesn't "Update" the database like in Access.

Another question i have is where do my Data Adapter and Dataset need to be dimensioned in memory? 'this loads my data from db into datagrid Dim con As New Ole Db. Connection String = "Provider=oledb.4.0;data source=dbsrc.mdb" con. Open() sql = "SELECT * from [Employee Assignments]" da = New Ole Db.

Tables("Assignments") 'this will eventually update the datagrid back into the db Dim cb As New Ole Db.

It should be noted that these statements are not performed as a batch process; each row is updated individually.

An application can call the Get Changes method in situations where you must control the sequence of statement types (for example, INSERT before UPDATE).

You can't insert a record as the data table does not recognize that it is in update, unless you call Data Row. hmmm so perhaps my approach to this is all wrong, Im pulling the table from an MS Access database and then need the SQL table to reflect.
