How can I find out if a button has Default set to true programmatically?

Call the GetDefID member function to get the ID of the default  pushbutton control for a dialog box.

returns:

A 32-bit value (DWORD). If the default pushbutton has an ID value, the  high-order word contains DC_HASDEFID and the low-order word contains the  ID value. If the default pushbutton does not have an ID value, the return value  is 0.

HIya Andy

Can you please give the code, assuming that the button has been given the variable

MyButton

associated with it.

DWORD dw = GetDefID();
if(dw != 0)  //is there a default button?
{
  ASSERT(HIWORD(dw) == DC_HASDEFID);  //safety check
  UINT nID = LOWORD(dw);  //Get the ID of the default button

  if(IDC_MyButton == nID)
    AfxMessageBox("MyButton is the default button !");
