I would like to read the attachment file size with c++ but my code don't compile if I write this code : 

auto myAttachment = dynamic_cast<Outlook::Attachment^>(attachment);
auto size = myAttachment->Size;


Compiler still return this error :
OutlookAttachmentEventsClass.cpp(18): error C2039: 'Size': is not a member of 'Outlook::Attachment'

If anyone can help me please.

Hello mephist,

Try Size(), not Size.

Hi Andrei,

Thanks for the answer.

I tried but I still have the same error.

However I saw the Size here while debugging my project so I don't understand why I can't use it.

Hello Lucky,

The issue is caused by using the interop for Office 2000: there's no Attachment.Size property in Office 2000. You have two ways:
- if you need to support Office 2000: before accessing that property you must check the Office version (AddinModule.HostMajotVersion), if the Office version is > 9 then you use late binding to get the value of that property.
- if you don't need to support Office 2000, replace the interops used: 1) remove the DLLs in the Interops folder of your add-in project, 2) remove the corresponding references from your project, 3) copy the corresponding interops from {Add-in Express installation folder}\Redistributables\Interop Assemblies\%Office version here% to the Interops folder of your project, 4) add references to the DLLs just copied to the Interops folder, 5) update your setup projects to deploy these interops (if required).
