TWebURLValidator
TWebURLValidator
is a non-visual component that allows to perform a check whether an URL
exists and works or not. Set the URL
to test via TWebURLValidator.URL
and call the Validate
method. This will trigger the OnValidated
event where the IsValid
parameter will return whether the URL
is valid or not.
Example:
procedure TForm1.WebFormCreate(Sender: TObject);
begin
WebURLValidator1.URL := 'http://myurltotest.com';
WebURLValidator1.Validate;
end;
procedure TForm1.WebURLValidator1Validated(Sender: TObject; IsValid: Boolean);
begin
if IsValid then
ShowMessage('The URL ' + WebURLValidator1.URL + ' works!');
end;
