CWnd::SendDlgItemMessage

Sends a message to a control.

LRESULT SendDlgItemMessage(
   int nID,
   UINT message,
   WPARAM wParam = 0,
   LPARAM lParam = 0 
);

Parameters

• nID
  Specifies the identifier of the dialog control that will receive the message.

• message
  Specifies the message to be sent.

• wParam
  Specifies additional message-dependent information.

• lParam
  Specifies additional message-dependent information.

Return Value

Specifies the value returned by the control's window procedure, or 0 if the control was not found.

Remarks

The SendDlgItemMessage member function does not return until the message has been processed.

Using SendDlgItemMessage is identical to obtaining a CWnd* to the given control and calling the SendMessage member function.

Example

void CMyDlg::SetSpinRange()
{
   //set the min and max range of the up/down or spin control
   SendDlgItemMessage(IDC_SPIN1, UDM_SETRANGE, 0, (LPARAM) MAKELONG (8, 1));
}
