            Exit Sub
        End If
        Dim strStocksIn As String

        strStocksIn = InputBox("Enter number of items : ", "Stocks In")
        txtQuantity.Text = Val(txtQuantity.Text) + Val(strStocksIn)
        Try
            sqL = "INSERT INTO StocksIn(ItemNo, ItemQuantity, SIDate, CurrentStocks) VALUES('" & txtItemNo.Text & "', '" & strStocksIn & "', '" & Format(Date.Now, "Short Date") & "', " & txtQuantity.Text & ")"
            ConnDB()
            cmd = New OleDbCommand(sqL, conn)
            Dim i As Integer

            i = cmd.ExecuteNonQuery()
            If i > 0 Then
                MsgBox("Stocks added successfully", MsgBoxStyle.Information, "Stocks In")
                Updateproduct()
            End If
        Catch ex As Exception
            MsgBox(ex.Message)
        Finally

推荐答案

private void AddStocksInUpdating()
{
	if (string.IsNullOrEmpty(txtItemNo.Text)) {
		Interaction.MsgBox("Please select item to add stocks.", MsgBoxStyle.Critical, "Select Item");
		return;
	}
	string strStocksIn = null;

	strStocksIn = Interaction.InputBox("Enter number of items : ", "Stocks In");
	txtQuantity.Text = Conversion.Val(txtQuantity.Text) + Conversion.Val(strStocksIn);
	try {
		System.Data.sqL = "INSERT INTO StocksIn(ItemNo, ItemQuantity, SIDate, CurrentStocks) VALUES('" + txtItemNo.Text + "', '" + strStocksIn + "', '" + Strings.Format(System.DateTime.Now, "Short Date") + "', " + txtQuantity.Text + ")";
		ConnDB();
		cmd = new OleDbCommand(System.Data.sqL, conn);
		int i = 0;

		i = cmd.ExecuteNonQuery();
		if (i > 0) {
			Interaction.MsgBox("Stocks added successfully", MsgBoxStyle.Information, "Stocks In");
			Updateproduct();
		}
	} catch (Exception ex) {
		Interaction.MsgBox(ex.Message);
	} finally {
		cmd.Dispose();
		conn.Close();
	}
}
