BOOL CGeomeSheet::OnInitDialog()

{

BOOL bResult = CPropertySheet::OnInitDialog();

// TODO: Add your specialized code here

// A pointer to each button we will need

CButton *btnOK, *btnCancel, *btnApply, *btnHelp;

// We will need to location and dimensions of Apply and Help

CRect RectCancel, RectApply, RectHelp;

// Get handles to all buttons

btnOK = reinterpret_cast<CButton *>(GetDlgItem(IDOK));

btnCancel = reinterpret_cast<CButton *>(GetDlgItem(IDCANCEL));

btnApply = reinterpret_cast<CButton *>(GetDlgItem(ID_APPLY_NOW));

btnHelp = reinterpret_cast<CButton *>(GetDlgItem(IDHELP));

// Get the location and the dimensions of the buttons

btnCancel->GetWindowRect(&RectCancel);

btnApply->GetWindowRect(&RectApply);

btnHelp->GetWindowRect(&RectHelp);

// Destroy the Help button

btnHelp->DestroyWindow();

// Convert the location and dimensions to screen coordinates

ScreenToClient(&RectCancel);

ScreenToClient(&RectApply);

ScreenToClient(&RectHelp);

// Put the Apply button where the Help button was

btnApply->SetWindowPos(NULL, RectHelp.left, RectHelp.top, 0, 0,

SWP_NOSIZE | SWP_NOZORDER | SWP_SHOWWINDOW);

// Put the Cancel button where the Apply button was
