event': improper syntax for specifying a COM event; did you forget '__interface'?
The wrong syntax was used for a COM event. To fix this error, change the event type or correct the syntax to comply with the COM event rules.
The following sample generates C3733:
#define _ATL_ATTRIBUTES 1
#include "atlbase.h"
#include "atlcom.h"
[coclass, event_source(com), // change 'com' to 'native' to resolve
uuid("00000000-0000-0000-0000-000000000001")]
class A
{
__event void func(); // C3733
};
int main()
{
}
