Hi Sagar,

Not exactly sure what you mean, but in general, if you want to make the
initialization of a member conditional, then do it inside the
constructor body -- something like:

ImpPDFTabGeneralPage::ImpPDFTabGeneralPage( Window* pParent, const SfxItemSet& rCoreSet )
    : <normal init here>
{
    if (mbIsPresentation)
        maRbRange = Radiobutton( this, PDFFilterResId( RB_RANGE_IMPRESS ) )
    else
        maRbRange = Radiobutton( this, PDFFilterResId( RB_RANGE ) )
}

Or you can avoid the double-initialization with adding a setResId()
method, so the resource id can be set later, after the ctor is already
called.
