How can I know if the user is pressing on a CButton for more than 250msec? (MFC CButton)

[rbid]

Hello, This question is for an MFC application. How can I know if the user is pressing on a button for more than 250msec? As far I know, I get the BN_CLICKED only once, and only when the user releases the button :( Any hint?:confused: -- **Ricky Marek** (_AKA: rbid_) -- "Things are only impossible until they are not" --- Jean-Luc Picard My articles

Create your own button class CMyButton, which subclasses the existing CButton. Add a handler for the WM_LBUTTONDOWN message to CMyButton. In the handler, post a notification to the parent dialog like this:

WPARAM wParam = MAKEWPARAM(GetDlgCtrlID(),BN\_PRESSED);
LPARAM lParam = (LPARAM)m\_hWnd;

GetParent()->PostMessage(WM\_COMMAND,wParam,lParam);

where BN_PRESSED is a notification code you've defined. In your dialog, add a handler for the BN_PRESSED notification. In the handler, start a timer (try using QueryPerformanceCounter). In your BN_CLICKED handler, get the value of the timer and compare the difference.
