Hello,

I’ve just installed version 9.7 on my environment and I find that I can’t compile my projects with it.  
The problem appears to be a change for the TROAsyncCallback type. Before (version 9.5 was the latest I had installed) it it was generated like this:

`typedef void __fastcall (__closure *TROAsyncCallback)(const _di_IROAsyncRequest aRequest);`

but now it is an abstract class/interface:

```
__interface TROAsyncCallback : public System::IInterface 
{
	virtual void __fastcall Invoke(const _di_IROAsyncRequest aRequest) = 0 ;
};

```

The problem is that the `_Intf` files include, for instance, this:

`virtual Uroasync::_di_IROAsyncRequest __fastcall BeginLoggedIn(const TROAsyncCallback aCallback, const void* aUserData = NULL) = 0;`

which can’t be compiled as now TROAsyncCallback is an abstract class, so it is not possible to create an instance.

I’m using RAD Studio 10.1 Berlin.

Thanks!

Hi,

weird, it wasn’t declared as abstract class or interface:

```auto
  {$IFDEF TROAsyncCallback_as_reqular_method}
  TROAsyncCallback = procedure (const aRequest: IROAsyncRequest) of object;
  {$ELSE}
  TROAsyncCallback = {$IFDEF DELPHI2009UP}reference to{$ENDIF} procedure (const aRequest: IROAsyncRequest);
  {$ENDIF}

```

workaround: try to uncomment `{.$DEFINE TROAsyncCallback_as_reqular_method}` in `RemObjects.inc`, rebuild packages and retest.

* * *

**Edit** : another workaround: manually change `TROAsyncCallback` with `_di_TROAsyncCallback` in `_Intf` file

Ok, I will try ASAP. I had to revert to the previous version.

I see that the bug was already fixed. What was the fix? I’m guessing changing it to `_di_TROAsyncCallback`?

Hi,

yes, codegen now generates \_Intf with `_di_TROAsyncCallback` for C++Builder.
