How to get Snapshotid in CreateDynaSet Method in VC++ (Using Oip8.tlb)

Question

While acessing the BFILE datatype in a table using the following
code in VC+6.0 on WINDOWS-95 OraDb.'GetCreateDynaset' is
throwing an Exception at 3rd parameter (i.e.,snapshot id).This
parameter is OPTIONAL in VB6.0 and it worked in VB6.0 (with out
SNAPSHOTID)
How can i access BFILE datatype through vc++ program?
OraSession OraSes;
     OraSes.CreateDispatch("OracleInProcServer.XOraSession");
     OraDatabase OraDb(OraSes.GetOpenDatabase
("prk_orcl", "scott/tiger", 0));
     OraDynaset ordyn;
The error is occuring at the following lines
------>     variantt *vsp=new variantt(ordyn.GetSnapshot(),true);
------->     OraDynaset OraDyn(OraDb.GetCreateDynaset("select
vdesc,vdata from voice_data",0,vsp));
     COleVariant index((short)1);
OraBfile OraMusic(OraDyn.GetItem(index));
     OraMusic.Open();
     OraMusic.CopyToFile("aa.wav",4096,0,4000);
     PlaySound("aa.wav",NULL,SND_ASYNC);

Hi,
the approach mentioned is correct. However, this line
(String)JSFUtil.getFromPageFlow("returnValue");
wont work if you write the return value in a managed bean
#{pageFlowScope.myBean.returnValue}
You need to read it from the managed bean and not from the memory attribute
