The first step is to show a _short_ snippet of what you have tried and the
exact text of the error message you get when it fails.

#import "c:\\myExampledll.dll"


MyNameSpace.MyClassptr mc=new MyNameSpace.Myclassptr();

at this line when I new an instance of that class at run time I get 'com
error' message ..

Hmm. I don't claim to know much about COM, but I would have thought that
you'd create an object with CoCreateInstance() or by calling the
CreateInstanceMethod() of a smart pointer class.

at this line when I new an instance of that class at run time I get 'com
error' message ..

That's it? No text? Did you remember to initialize the COM library by
calling CoInitialize[Ex]()?
