Define a Response function in your Property Sheets' response table like so:

DEFINE_RESPONSE_TABLE1(MyPropertySheetClass, TPropertySheet)

EV_COMMAND_AND_ID(IDOK, HandleOkButton),

END_RESPONSE_TABLE;

The handler would look like:

void TMyPropertySheetClass::HandleOkButton(WPARAM wParam)
{
    switch(wParam)
    {
        case IDOK:
            // do something.....
            Apply();
           
            break;
    }
}

Property Sheets aren't easy.  I have a paper on them somewhere...

Hope this helps:-)

Thanks for your answer

...Before asking for help, I've tried to define a Reponse function but whith a wrong parameter type ( my french documentation is ::HandleFunction(uint param) and not HandleFunction(WPARAM param) )
I've tried your example but I still can't intercept OK Button

I've set a Breakpoint on the response function but the application never stop at this point

Here is a part of my code

class TCenteredPropertySheet : public TPropertySheet
  {
  public:
    TCenteredPropertySheet(TWindow* parent, char* title, int startPage = 0, bool isWizard = false, uint32 flag = SH_DEFAULT );

  protected:
    void           SetupWindow();
    void           ButtonClicked(WPARAM param);      

  public:
    DECLARE_RESPONSE_TABLE(TCenteredPropertySheet);
  };

DEFINE_RESPONSE_TABLE1( TCenteredPropertySheet, TPropertySheet)
EV_COMMAND_AND_ID(IDOK, ButtonClicked),
END_RESPONSE_TABLE;


TCenteredPropertySheet::TCenteredPropertySheet( TWindow* parent, char* title, int startPage,                                              bool isWizard, uint32 flag ):
TPropertySheet( parent, title, startPage, isWizard, flag )
  {

  }


void TCenteredPropertySheet::SetupWindow()
  {
  TPropertySheet::SetupWindow();
  TRect rc;
  GetWindowRect( rc );
  TScreenDC dc;
  int nX = dc.GetDeviceCaps(HORZRES) / 2 - rc.Width() / 2;
  int nY = dc.GetDeviceCaps(VERTRES) / 2 - rc.Height() / 2;
  SetWindowPos( HWND_TOP, nX, nY, 0, 0, SWP_NOSIZE );
  }


void TCenteredPropertySheet::ButtonClicked(WPARAM param)
  {
  if( param == IDOK )
    CheckAllPage();
  }
            

I really don't understand why !!!

Are you calling EnableSubclass(true); in the constructor of your Property Sheet?

What the F... is EnableSubclass ??? I grepped my entire set of includefiles, but there is no EnableSubclass.
Furthermore, why don't you use EV_COMMAND instead of EV_COMMAND_AND_ID.
please djfr help me!!

What version of the Borland compiler are you running with?  I am using 5.02.  If your version is pre 5.x, I don't believe you'll find it.  The reason I use EV_COMMAND_AND_ID is so that I can have one function that handles multiple WM_COMMAND messages.
