Suppose I add a new row to a table in a dataset, and then I use an
OleDbDataAdapter to add that new row to a SQL Server database using
OleDbDataAdapter.Update(), as in the following code:

newRow.post_text = this.lblHiddenMessageStorage.Text;
newRow.post_datetime = System.DateTime.Now;

Hi everyone,
I am using VB.NET 2003 and an OleDBDataAdapter to update an Access table's
DateTime field. The field's format is set to "General Date" (ie: 11/24/2004
8:00:00 AM). The problem is the field ends up with only a date, with no time
component.

Hi,
I need to update tables in access 97. The table names have spaces (not my
choice). My update fails even though I use the OleDbCommandBuilder.
Here is a code I am using
myDataAdapter = New OleDbDataAdapter
myDataAdapter.SelectCommand = New OleDbCommand("Select * from ", MyConnection)
Dim cb As OleDbCommandBuilder = New
OleDbCommandBuilder(PatientsBillingDataAdapter)

I create 2 data OleDbDataAdapters, one with the wizard, and one in
code. I know the adapter created in code is OK because I use it to
fill a data table.
However, when I try to use the same SQL insert statement in the two
adapters, the adapter created with the wizard works fine, but the
adapter created in code gives me an error "Object reference not set to
an instance of an object". The code is below. What am I doing wrong?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
