void __fastcall TForm1::Timer2Timer(TObject *Sender) { if (KEYDOWN(32)) { Событие } }

How to set a range in place of a single-key code?

    write something like if (KEYUP(32) | KEYUP(100) | KEYUP(122)) ? - KoVadim

What does KEYDOWN do? I did not find it in Google.

Now in the case: if you need a range, you can write an auxiliary function that runs through the entire range and performs a KEYDOWN check with each element of the range:

 bool KeyDownRange(int start, int end) { for (int i = start; i <= end; i++) { if (KEYDOWN(i)) { return true; } } return false; }

And then in your function:

 void __fastcall TForm1::Timer2Timer(TObject *Sender) { if (KeDownRange(32, 64)) { Событие } }

  • {int c; int w = 15; for (c = 0; c <= 3; c ++) {w ++; if (KEYDOWN (w)) {Timer1-> Enabled = false; }}} This is how it works. - Dima
