Hi,
  I created a COM component using theATL wizard. I added an interface IX. I implemented this interace in a class CIX. I added a member variable to CIX...this is actually a _ConnectionPtr object. Now, I wrote some code in the constructor of CIX to initialize the connection object.
  But my CoCreate instance is failing now! If I comment out the code in the constructor things work fine! Wats the matter?

Please post your code.

Post the complete constructor code, and exactly what you're commenting out.

may be your code generate exception in the constructor, use try/catch and debug it.
