SYMPTOMS
Adding a method to an ATL class generates the following compile time error:

MIDL2269 : procedures in an object interface must return an HRESULT



CAUSE
The method implements a custom interface, does not use the [local] attribute, and does not return a value of type HRESULT.



RESOLUTION
Add the [local] attribute to either the interface or the method.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

This problem was corrected in Microsoft Visual C++ .NET.



Steps to Reproduce Behavior

 * 1) Create a default ATL project.
 * 2) Right-click the project in ClassView and select New Class.
 * 3) In the New Class dialog box, select ATL Class as the class type.
 * 4) Enter a name for the class, and select Custom for the Interface type. Click OK.
 * 5) Right-click the interface in ClassView and select Add Method.
 * 6) In the "Add Method to Interface" dialog box, select any return type other than HRESULT.
 * 7) Enter a method name, and specify the parameters. Click OK.
 * 8) Build the project.
