Question:
I want to call the Windows RegisterClass() function, but I get the
error "Incompatible types: 'TPersistantClass' and 'TWndClassA'"
when compiling. How can I get around this?
Answer:
The RegisterClass() function is declared both in the Classes unit
and the Windows unit. To call the Windows version, simply
prefix the call with the unit name.
Example:
procedure TForm1.Button1Click(Sender: TObject);
wc : TWndClass;
begin
Windows.RegisterClass(wc)
end;
