-'method': an non-managed event source method must return void or an integral type
+> 'method': an non-managed event source method must return void or an integral type
 
 You defined a method in the event source that did not return void or an integral type. To fix this error, make the event and event handler have a return type of **`void`** or an integral type such as **`int`** or **`long`**.

 You defined an event handler method that did not return the same type as the source event method. To fix this error, give the event handler method the same return type as that of the source event method.

 You defined an event handler method that did not use the same parameters as the source event method. To fix this error, give the event handler method the same parameters as those of the source event method.

-'method': an event handler method must have the same calling convention as the source 'method'
+> 'method': an event handler method must have the same calling convention as the source 'method'
 
 You defined an event handler method that did not use the same calling convention as the source event method. To fix this error, give the event handler method the same calling conventions as those of the source event method. For example, in the code below, make the calling conventions of `handler1` and `event1` match ([__cdecl](../../cpp/cdecl.md) or [__stdcall](../../cpp/stdcall.md) or others). Removing calling convention keywords from both declarations will also solve the problem, and cause `event1` and `handler1` to default to the [thiscall](../../cpp/thiscall.md) calling convention. See [Calling Conventions](../../cpp/calling-conventions.md) for more information.

 You specified a pointer in [`__hook`](../../cpp/hook.md) or [`__unhook`](../../cpp/unhook.md) that did not point to a valid class. To fix this error, ensure that your **`__hook`** and **`__unhook`** calls specify pointers to valid classes.

-'method': a method that fires events cannot be defined
+> 'method': a method that fires events cannot be defined
 
 You declared an event method that includes an implementation. An [__event](../../cpp/event.md) method declaration cannot have a definition. To fix this error, ensure that no event method declarations have definitions. For example, in the code below, remove the function body from the `event1` declaration as indicated by the comments.

 The windows.h file is required if you use multi-threading with events. To fix this error, add `#include <windows.h>` to the top of the file in which event sources and event receivers are defined.
