<p>I'm using the MVP pattern in a windows form app. I need to change a radio button on the view. I can do this by exposing a Boolean property on the view, but should I be using events to manipulate the view instead?</p>
| <p>It's a matter of purity vs being pragmatic... and a bit of personal style. Shouldn't matter... events are just more work than normal methods but more decoupled.

<p>I have the need/desire to learn to program against Win32 in C++. I am a little confused as to what Win32 even is, as I have no experience on the platform. </p>
<p>What would you recommend to get me started programming and debugging C++ programs on Win32?</p>
| <p>Answering your (original) questions one by one:</p>
<hr>
<p><strong>1/ Will anyone tell me what Win32 is?</strong></p>
<p>Win32 is the application programming interface (API) for Windows. Specifically, it's for 32-bit Windows and beyond since the old API was for the primarily 16-bit versions of Windows, Windows ... | <p>Formally the Windows API is Microsoft's core set of application programming interfaces. For someone in a hurry! Get Microsoft Visual Studio. Start it up and choose Files->New Project and select Visual C++ and Win32 Console Application. This will get you started quickly and debugging is easy.</p>
