Hi,
I am playing with samples from Petzold's Programming Windows converted by Andrej Mitrovic. Many thanks, Andrej. :-) My question is about string conversion. There is a function in virtually every sample named "toUTF16z", which if I understand properly, converts string to UTF-16, so that they can be sent to various Windows API functions. But string literals, for example in MessageBox, are fine, no conversion is needed. I don't understand the magic, what is converted, and when?
If some variable was used e.g. "appName.toUTF16z", and not "Error".toUTF16z
