My question is about Delphi 7.
I need to get currently selected ComboBox1
value to use it as Floating point variable in my code:
t:=t+ComboBox1. // Not sure what to write here...
Thank you!
Not sure if the TryStrToFloat is already in Delphi 7, but if yes I would do it this way.
procedure TForm1.ComboBox1Change(Sender: TObject);
var
Value: Double;
begin
if TryStrToFloat(ComboBox1.Text, Value) then
T := T + Value
else
ShowMessage('You''ve entered wrong value ...');
end;
