In this exaple we explain how to call the mmsys.cplဠfrom delphi using the ShellExecute procedure. The mmsys.cpl is the multimedia system from control panel.
To call a cpl application you need to execute the 'rundll32.exe' with a param that is the name of the cpl that you need.
Ex. you have a Tform with a btn :
Sample Code :
implementation
{$R *.dfm}
uses shellapi;
procedure TForm1.Button1Click(Sender: TObject);
begin
ShellExecute(Form1.Handle, nil, 'rundll32.exe','shell32.dll,Control_RunDLL mmsys.cpl', nil, SW_SHOW);
end;
end.
