[C++ Programming]

hello Friends

I m creating a one dlu for 3dsmax using INode* root_node,when i use this root_node in my current Dlu then i m able to getting its values by excessing its function that r returning right values.

But when I creat another dll and in that in tht dll I create one function tht i m exporting and passing this INode object to that dll.That object is not null there but when i try to excess some values by using its function then it returns nothing.

Do u hv any Solution?
