VB错误 - System.Data.dll中发生未处理的“System.Data.OleDb.OleDbException”类型异常

Question

我在使用此代码的表单中收到错误：

Private Sub btnCommit_Click(sender As Object, e As EventArgs) Handles btnCommit.Click  
        ' Select Case MsgBox("Are you sure to Save this record?", MsgBoxStyle.YesNo, "Save")  
        'Case MsgBoxResult.Yes  

        row = maxRows  

                txtProductID.Text = CStr(row)  

                maxRows = maxRows + 1  


                txtProductID.Text = CStr(maxRows)  

                If row <> -1 Then  

                    Dim cb As New OleDb.OleDbCommandBuilder(productAdapter)  

                    Dim mynewrow As DataRow  

                    mynewrow = productDataset.Tables("ProductTable").NewRow()  

                    mynewrow.Item(0) = CInt(txtProductID.Text)     
                    mynewrow.Item(1) = txtDescription.Text       
                    mynewrow.Item(2) = txtSize.Text     
                    mynewrow.Item(3) = txtQoh.Text       
                    mynewrow.Item(4) = txtUnitPrice.Text        
                    mynewrow.Item(5) = txtWarranty.Text      
            productDataset.Tables("ProductTable").Rows.Add(mynewrow)        
                    productAdapter.Update(productDataset, "ProductTable")        
                    MsgBox("Record added to database")        
                    btnCommit.Hide()        
                    btnAdd.Show()     
                    btnUpdate.Show()  
                    btnDelete.Show()  
                End If      

        '  Case MsgBoxResult.No  

        ' End Select  
    End Sub 

错误发生在productAdapter.Update(productDataset, "ProductTable")行，它说

  

“System.Data.OleDb.OleDbException”类型的未处理异常

发生在System.Data.dll。

我使用了另一种形式的相同代码，并且工作正常。

这里有什么问题？
