Hi, i TRY to create a windows apllication that insert in a Access DB
name and surname; the Insert istruction Works but the the refresh of
DataGridView doesn't works...
the code is :
public Form1()
{
InitializeCompo nent();
}
#region Variabili
string connString = "Provider=Micro soft.Jet.OLEDB. 4.0;" +
"Data Source=C:\\db1. mdb";
string querySelect = "select * from TabNomi";
string queryDel = "delete * from TabNomi";
DataTable dt = new DataTable();
BindingSource bsource = new BindingSource() ;
#endregion
private void Form1_Load(obje ct sender, EventArgs e)
{
OleDbDataAdapte r Dada = new OleDbDataAdapte r(querySelect,
connString);
OleDbCommandBui lder Cbil = new OleDbCommandBui lder(Dada);
Dada.Fill(dt);
//BindingSource bsource = new BindingSource() ;
bsource.DataSou rce = dt;
dataGridView1.D ataSource = bsource;
}
private void button1_Click(o bject sender, EventArgs e)
{
string queryInsert = "insert INTO TabNomi
VALUES('luca',' pino')";
OleDbDataAdapte r da = new OleDbDataAdapte r(queryInsert,
connString);
OleDbCommandBui lder Cbil = new OleDbCommandBui lder(da);
da.Fill(dt);
//BindingSource s = new BindingSource() ;
bsource.DataSou rce = dt;
dataGridView1.D ataSource = bsource;
}
} 4 4955
If it isn't auto-updating, you could call ResetBindings() on the
BindingSource; you could also change the binding (your current lines are
trivial updates - i.e. they don't change anything, so it won't refresh).

i put the istruction ResetBindings() but the datagridview don't
refresh...
private void button2_Click(o bject sender, EventArgs e)
{
string queryInsert = "insert INTO TabNomi
VALUES('marco', 'pino')";
OleDbDataAdapte r da = new OleDbDataAdapte r(queryInsert,
connString);
OleDbCommandBui lder Cbil = new OleDbCommandBui lder(da);
da.Fill(dt);
bsource.ResetBi ndings(false);
bsource.DataSou rce = dt;
dataGridView1.D ataSource = bsource;
}
In that case... are you sure that the DataTable has been updated by the
adapter? Try manually finding (loop or whatever) the record in the "dt"
DataTable; is it there?

Hi,
I have been encountering a refresh problem with DataGridView, which is bound
to a DataTable.
When I make updates (Add, Delete, update) to the DataGridView, everything
flow nicely to DataTable. No problem here.
However, when I add data (programatically) to the DataTable, the
DataGridView does not refresh right away. If I minimize and show my form,

Hi all,
I'm having a weird time with a call to the Refresh() method of a
DataGridView. I have a VB.NET 2005 Windows application with a main form and
a "worker" thread. The main form delegates a Sub to the worker so that the
latter can refresh the DataGrid after updating the DataTable driving it.
When I run the app under the debugger, everything's fine. But when I run it
for real, it hangs, apparently in the Refresh() method of the...

Ok, extremely wierd situation here:
(I'll post the code below, after the explanation)

a DataGridView embedded. The user presses a button to do a SQL query
(fill a DataSet). Before firing the query, I disable the grid/buttons
and turn on UseWaitCursor. After it completes, I re-enable the grid/
buttons, refresh the dataset, then turn off the UseWaitCursor. If I...

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.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
