Hi Bruce,
Thanks, but that's not the answer.
In my previous e-mail I gave an example in which I had tried that very
proceedsure,:
I have tried to pass true as a parameter, by using the true literal to set
p3 like so:
var p1, p2;
var p3 = true;
var MyHotkey = Keyboard.RegisterHotKey("Control-Shift-Windows-h",
"SpeakHelloWorld", [p1, p2, p3]);
I all so explained that I had recieved the error:
"Line 4 Column 1 The specified function does not have the proper number or
types of parameters. < 0x8004E001. However I had not tried leaving p3 outside
the square bracketts, I have now, and no joy. The script runs as explained in
the previous e-mail without error and does not change the firstPress parameter.
Warm regards.
Martin Webster.
