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?

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

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.
