windows - Consecutive interface function IDs -


I have a COM object interface such as 

  interface interface: IDispatch {[id (1)] HRESULT FunA (...); [ID (2)] HRESULT FunB (...); [ID (3)] Hairsault Funk (...); }

Should the ID be consistent? Or can I define it as 

  interface interface name: IDispatch {[id (1)] HRESULT FunA (...); [ID (3)] HRESULT FunB (...); [ID (5)] Hirselt Funk (...); }

It seems ok to compile the second version, but can there be any problems at runtime?

The actual ID values ​​are arbitrary numbers; they do not need to be consistent; They just have to be unique, by hypnosis, there are zero and negative values, besides, there is no rule.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment.
