Hi,

        I am writing Multi-tier application by using C++Builder 3.  How can
I use TBookmarkList:::Items[i] associate with  TDataSet::GotoBookmark(void
*Bookmark).  TBookmarklist:::Item[i] will return "AnsiString Bookmark",
however TDataSet::GotoBookmark will only take "void *" as an argument.
Thanks in advance!!

Regard,
Maverick

There are 2 types of Bookmarks.  TBookmark which is a pointer and
TBookmarkStr which is a long string (AnsiString).  Use
DataSet1->Bookmark = Bookmark; to use the AnsiString version.
GotoBookmark, FreeBookmark and GetBookmark are used for the pointer
version.  The pointer version was introduced in Delphi1 before long
strings (AnsiString) which was introduced in Delphi 2.
