Overriding OK button in CPropertySheet

Hello all,

I simply wish to override the default implementation of the OK button in
the CPropertySheet. I do not mean simply overriding the OnOK() function,
which is too late as it has already OnApply()ed to every "dirty" page.
I'm guessing I need to override ON_COMMAND but I am not sure which
parameters (wParam, lParam) to check for IDOK.

Thanks in advance,

Why not override OnApply() instead? Or in addition?

Command messages don't have parameters; see the online help for "WM_COMMAND 
message handler", which shows the function prototype. So you ought to be 
able to manually add to the message map:

BEGIN_MESSAGE_MAP(CMyPropSheet, CPropertySheet)
    //{{AFX_MSG_MAP(CMyPropSheet)
    //}}AFX_MSG_MAP
    ON_COMMAND(IDOK, OnOK)
END_MESSAGE_MAP()

void CMyPropSheet::OnOK()
{
  TRACE("CMyPropSheet::OnOK\n");
  // Do whatever you want.
}

I believe this will completely hide the default behavior.

Hi

If idea is to just handle the IDOK message of Property sheet 

I do it this way,

BOOL CMySheet::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) 
{
	// TODO: $B$3$N0LCV$K8GM-$N=hM}$rDI2C$9$k$+!"$^$?$O4pK\%/%i%9$r8F$S=P$7$F$/$@$5$$(J
	BOOL ret ;
	if(nID == IDOK)
	{
		.... Your code goes here .....
		ret = < Set based on Ur conditions >
	}
	else
	{
		ret = CPropertySheet::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
	}
	return ret ;
}

Hope this helps

Tips
