Hello Msrsas? (please sign posts using a real name, it makes exchanges much more friendly)

1. If I use "readNodeFile" and try to print out using std, it gives the error as error 
LNK2019: unresolved external symbol "__declspec(dllimport) public: class 
std::basic_ostream<char,struct ......
*I have added necessary header files.

You're not being very precise (including actual code would have helped), but this sounds like you're trying to do something like this:

osg::Node* node = osgDB::readNodeFile("somefile.osg");
std::cout << *node << std::endl;

Now, unless I'm mistaken, this cannot work because nowhere in OSG is an output operator (operator<<) defined which takes an osg::Node. That's why you'd be getting an error about an unresolved external symbol, because the linker is trying to find this output operator but it isn't defined anywhere. You could make one if you want.

2. QSG Picking example gives the output but if i click on the cow object it gives error 
as "Unhandled exception at 0x7c901230..." and ask for user breakpoint in 
dbgheap.c file.
    I have tried intersection using line intersector in other program but the 
same error occurs.

Seems to me like you're trying to dereference a null pointer? Again, relevant code would help and perhaps also a stack trace... "Unhandled exception" is just a generic error message meaning "something went wrong", without more info no one could do more than guess at what exactly might be going wrong.

Hope this helps,

J-S
