creating new buttons && view the one that's clicked

Hi,

I'm creating a whole bunch of buttons during run-time. When anyone of these buttons is clicked it should go through the same function, but with different parameters. A small example to clarify;

for (x = 0; x < 10; x++)
{
TButton *b = new TButton(this);
b->Caption = "My button " + IntToStr(x);
b->Top = 100;
b->Left = 100 + 10 * x;
b->OnClick = myfunction(x);
b->Parent = this;
}

void __fastcall TForm1::myfunction(int x)
{
ShowMessage("Button " + IntToStr(x) + " clicked");
}


This, however, doesn't work. I get an "Not an allowed type" error when compiling. Apparantly I can't pass variables like this to myfunction.


I can only do something like this;
b->OnClick = myfunction;

void __fastcall TForm1::myfunction(TObject *Sender)
{
ShowMessage("Button ? clicked");
}


But how do I know which of the ten buttons is clicked now? How can I pass this information to the function?

thanx
Willem
