What's wrong? (Expression type must be BOOLEAN)
What's wrong with my code? I am getting this error:
[error dcc32] Unit6.pas (83): E2012 Expression type must be BOOLEAN
function checkver(): boolean;
begin
//some code here
end;
function refresh(): boolean;
begin
//some code here
end;
procedure TForm6.FormCreate(Sender: TObject);
begin
if checkver() then
if refresh() then //Error is HERE!!
//some code here
end;
( full code )

TControl
(from which your form class is generated) has a Refresh
method of its own and it does not return a boolean. The scope of this method is closer than the scope of a single-level method of the same name, because you write code in a method of that class, so the compiler binds to the method Refresh
, not the function Refresh
.
Call <unitname>.refresh
to get a unit level function instead of a method.
