I have already binded a data source from Access to my visual basic program but need to add a True/False column to two of the tables. I could do this manually in access and re-bind the sources but that would take up too much of my time so I wanted to know if I'm using the proper code to add a column to the data table directly from VB? Here is the code I want to try but I don't know where to place it?
OleDbCommand = OleDbCommand("ALTER TABLE tableName ADD
FieldName DataType");
(something).Connection = OleDbConnection;
[Code]....
I'm not sure what goes into the "something" parenthesis and where this code must go. I already tried editting through the data designer but although it shows the column in the DataGridView, it does not save any data or the column into the actual access file.

Im looking to add some information to a table in VB.net.The table needs 2 columns and a number of rows;1 Column needs to have numbers ranging from 1 onwards, basically representing their row number. And 1 more column which just displays any text when a button is pressed.
Each time the button is presed i need the text to go onto a new row.Ive heard alot about a DataGrid, but everything relating to this seems to be based with SQL and I was wondering if there is a differnet tool which would be simpler to use?

I am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks.
cnn1.Open("Driver={Microsoft Visual FoxPro Driver};" & _
"SourceType=DBC;" & _

how to add a new row to a table via visual basic 2008, this is what I have been trying and it does not seem to work
newdatarow = dataset.table.newrow
I have an access database with a couple of tables (each with a couple of fields).
in the vb form i have databindsource for two tables each table's fields are shown in textboxes (whose displaymember has been set to each field).
I tried adding a new row to the table like this:
Mbindingsource1.addnew()
textbox1.text="df"
textbox2.text="tttt"
me.Mbindingsource1adapter.update(me.missiondataset.Mtable)
I don't get it, it works just fine for one table but doesn't work for the other which simply doesn't add anything.
I am already exporting datagridview to ms excel and I need to add a row for "Total" but I've encountered a problem because I don't know how to merge the cells for my "Total" since the code for that is placed in a for-loop, there is no exact cells to be assigned for "Total" because it depends on the number of rows in the table. As a result, "Total" is placed in each cell in a row at the end of the table.
