CreatePolyline

   I'got problem again. 
while I'm using the method CreatePolyline(...) of IObjectManager5Ptr ,
I don't know how to write the first parameter.I'm using Vc6. I want to use the defaultvalue(0),I don't know how to write it in c++. if I use 0 directly the compiling can not pass.
I mean When I write:
 PolylineTemp = m_ObjectManagerptr->CreatePolyline(0, 0x0000ff,HSC_TERRAIN_ABSOLUTE, GroupID,"Route");
The complier will report error. And I know in C# the first parameter could be "null".But I don't know how to write the first parameter by meaning the defaultvalue 0;
