Ruslan,

Yes, it is very easy to demonstrate.

If you take the MyDatabase.h file and make simply change the first 
field from
a VDK_String to a VDK_VarChar, you will get the link error.

class MyBaseObject : public VDK_BaseObject
{
	public:

		VDK_VarChar		mfField1;	// This is now VDK_VarChar instead of 
VDK_String
		VDK_String		mfField2;
		VDK_Short		mfField3;
		VDK_Double		mfField4;
		VDK_ULong		mfField5;

	public:
		
		MyBaseObject( void ) : VDK_BaseObject( "MyBaseObject" ),
			mfField1( "Field1", 40 ),
			mfField2( "Field2", 40 ),
			mfField3( "Field3" ),
			mfField4( "Field4" ),
			mfField5( "Field5" )
		{
		}
};
