In Reply to RadioButton - Making a choice and continuing posted by Lionel on
February 27, 2006
: I am using the following code to select one of two possiable edit boxes choices and
continuing with the application. If the user does not check the RadioButton associated with the selection
the application crashes. ?
: This is the way I have it set up for now:
: //************************************
: if RadioButton1.checked then
: Radius:=Edit2.Text;
: Tangent:=Radius*Tan(X/2);
: //----------------------------------------------
: if RadioButton2.checked then
: Tangent:=Edit3.Text;
: Radius:=Tangent/Tan(X/2);
: //***************************************
: I tried the following line but it still crashes.
: else
: ShowMessage('You forgot to check your selection)'
while (not RadioButton1.Checked) and
(not RadioButton2.Checked) do begin
ShowMessage('You forgot to check your selection');
Application.ProcessMessages;
end;
if RadioButton1.Checked then begin
Radius := Edit2.Text;
Tangent := Radius * Tan(X/2);
end
else begin
Tangent :=Edit3.Text;
Radius := Tangent / Tan(X/2);
end;
Good luck! webmaster Guido
