How can I check if a certain character was pressed?

 

1.

  Start a new project using File | New Application.

 

2.

  Double-click the OnKeyPress event:

 

void __fastcall TForm1::FormKeyPress(TObject *Sender, char &Key)

{

    ShowMessage("You pressed " + String(Key));

}

 

The OnKeyPress event lets you handle key presses. Its Key parameter contains the name of the key.
