Hi,

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Try
            Dim i, c As Integer
            Dim a, b As Integer
            i = ListView1.Items.Count - 1
            While i >= 0
                a = ListView1.Items.Item(i).Text
                b = ListView1.Items.Item(i).SubItems.Item(1).Text
                c = ListView1.Items.Item(i).SubItems.Item(2).Text

                Dim QUERY As String
                QUERY = "INSERT INTO stockinhand(stockcode,stocknamename,quantity)VALUES ('"+ a +"','" + b +"','" + c + "')"
                EXECUTEQUERY(QUERY)
                MsgBox("saved")
            End While
        Catch eEndEdit As System.Exception
            System.Windows.Forms.MessageBox.Show(eEndEdit.Message)

我不是VB专家，但这是在C#中的实现方法

I''m no expert with VB but here is how it would be done in C#

for (int i =0; i< listView1.Items.Count; i++)
{
 string value = listView1.Items[i].Text;
 string Query = "INSERT INTO stockinhand(stockcode,stocknamename,quantity)VALUES ('" + value + "')";
}

或

or

string Query = String.Format("INSERT INTO stockinhand(stockcode,stocknamename,quantity)VALUES ('{0}')",value);
