Hi,
I momentarily forgot how to do this... It's late in the week. ;)
I have set items in a Set type. How to I count how many items are in the set?
eg:
TfpgMsgDlgBtn = (mbNoButton, mbYes, mbNo, mbOK, mbCancel, mbAbort,
mbRetry, mbIgnore, mbAll, mbNoToAll, mbYesToAll, mbHelp, mbClose);
TfpgMsgDlgButtons = set of TfpgMsgDlgBtn;
....
var
Buttons: TfpgMsgDlgButtons;
....
Buttons := [mbRetry, mbIgnore]; // it can be any amount of items.
How do I know how many items are in Buttons?
Yes I can do a....
for i := Low(TfpgMsgDlgBtn) to High(TfpgMsgDlgBtn) do
begin
if i in Buttons then
int(counter);
end;
Is there a better/quicker way of doing this?
Regards,
- Graeme -
