Ejemplo

// TODO: Replace the strings below with the appropriate message,  
// main instruction, and dialog title.
CString message("This is an important message to the user.");
CString mainInstruction("Important!\nPlease read!");
CString title("Alert Dialog");

CTaskDialog taskDialog(message, mainInstruction, title, 
    TDCBF_YES_BUTTON | TDCBF_NO_BUTTON | TDCBF_CANCEL_BUTTON );

taskDialog.AddCommandControl(201, L"First command button control");
taskDialog.AddCommandControl(202, L"Second command button control");
taskDialog.AddCommandControl(203, L"Third command button control");

// Show the CTaskDialog and remember how the user closed it. 
int selection = taskDialog.DoModal();

switch(selection)
{
case 201:
    // TODO: Place processing here for the first  
    // command button control. 
    break;

case 202:
    // TODO: Place processing here for the second  
    // command button control. 
    break;

case 203:
    // TODO: Place processing here for the third  
    // command button control. 
    break;

default:
    break;
}

// Remove all the command controls so that we can use the same task 
// dialog with new command button controls.
taskDialog.RemoveAllCommandControls();

taskDialog.AddCommandControl(301, 
    L"New first command button control");
taskDialog.AddCommandControl(302, 
    L"New second command button control should require elevation",
    TRUE, TRUE);
taskDialog.AddCommandControl(303, 
    L"New third command button control should be disabled");

// Change the default command button control
