去掉CPropertySheet中的帮助按钮后,如何修改外观

去掉CPropertySheet中的帮助按钮后,怎么修改外观?
去掉CPropertySheet中的帮助按钮后,右边还是有一块多出来的地方,很不美观。
请教高手帮忙!!

SetWindowPos(...)

PSH_HASHELP
Permits property sheet pages to display a Help button. You must also set the PSP_HASHELP flag in the page 's PROPSHEETPAGE structure when the page is created. If any of the initial property sheet pages enable a Help button, PSH_HASHELP will be set automatically. If none of the initial pages enable a Help button, you must explicitly set PSH_HASHELP if you want to have Help buttons on any pages that might be added later.

------解决方案--------------------
帮助按钮是否出现应该与页面是相关的。在每个页面的构造函数中加入:
m_psp.dwFlags &= (~PSP_HASHELP);即可
------解决方案--------------------
CPropertySheet中也要加入一行
m_psp.dwFlags &= (~PSP_HASHELP);

为CPropertySheet添加初始化函数OnInitDialog(); 
下面我是去掉“应用按钮”,要去掉“帮助”按钮是一样的做法的。

BOOL CPropertySheet::OnInitDialog() 
{
BOOL bResult = CPropertySheet::OnInitDialog();

CRect rcApply,rcCancel;

CButton* buttonApply=(CButton*)GetDlgItem(ID_APPLY_NOW);
buttonApply->GetWindowRect(rcApply);
buttonApply->DestroyWindow();
CButton* buttonCancel=(CButton*)GetDlgItem(IDCANCEL);
buttonCancel->GetWindowRect(rcCancel);
ScreenToClient(rcApply);
buttonCancel->MoveWindow(rcApply,TRUE);

CButton* buttonOk=(CButton*)GetDlgItem(IDOK);
ScreenToClient(rcCancel);
buttonOk->MoveWindow(rcCancel,1);

return bResult;
}
