Hello,

Shift: TShiftState;

TShiftState = set of (ssShift, ssAlt, ssCtrl,
    ssLeft, ssRight, ssMiddle, ssDouble);

Ok, but its not compatible with others languages like C++
So i need to make it compatible in my Param, like

TMyParam = packed record
  kbShift: DWORD;
end;

I'm doing in this way...

if ssShift in Shift then
kbShift := Integer(ssShift);
if ssAlt in Shift then
kbShift := kbShift or Integer(ssAlt);
if ssCtrl in Shift then
kbShift := kbShift or Integer(ssCtrl);
//for each type i need to do it, but maybe a loop can do this?
...

So i can call the reverse way like

if ssCtrl in kbShift then
...

But, i think there is a better way to do that... i tried to loop but no success

kbShift := -1;
for i := Low(TShiftState) to High(TShiftState) do
if (TShiftState(i) in Shift) then
kbShift := kbShift or TShiftState(i);
...

not work! hehe

Some idea?

Regards,
Carlos
