Hi,
New to this programming stuff. Personal project going on and I am not sure if I am getting the results I am looking for.
I am using visual studio pro, windows forms.
I want to know is it possible to send messages to the listbox display as a result dialog.
I.E;

C++

hr = m_directoutput.GetDeviceType(hDevice, &typeguid);
if (FAILED(hr))
{
    // flag this error
}

How do I send this error message to the listbox, Better yet, what do you call this action in a manner to which I can get more information in doing this using google?
I have searched all over and still no answer.

Thanks in advance

Tab your UI library: WPF, Forms, what? The answer depends on it.

Since you are using Winforms, the easiest approach is to have a form with a single ListBox (docked to fill the form), and send it strings that are added to the ListBox. And no, this is not an unusual approach at all. Logging listboxes have been popular since the Win16 days.

You have tagged your question with C++/CLI, so I would suggest that you use _com_error[^] to convert the hresult to a formatted error message string.
