Outlook demo not working on win64

[markwilliams1234]

I am running outlook in 64 bit and I have compiled the outlook demo in 64 bit (Delphi 10.4). When I try and drag an email into the app it is not accepted and the cursor icon never changes from the barred icon.

[landrix]

which demo?

Outlook or OutlookSource ?

[markwilliams1234]

Didn’t realise (until now) there were two. I am having a problem with the Outlook demo, but have also tried the Outlook Source just now and same problem. However, I don’t think Outlook Source is set up to handle drag & drop direct from outlook.

you are right, mapi don't works currently under win64. i don't have any solution for this. It has nothing directly to do with drag and drop. for me, the application crash at MAPIInitialize

Hi, The problem is in the MAPIUtil.pas unit.
the headers are different if accessing with Win64bits application.
you have to remove the 'Historic Stack correction'
example :
HrGetOneProp:=GetProcAddress(MAPIDLLHandle,'HrGetOneProp@12');
must be replaced by
HrGetOneProp:=GetProcAddress(MAPIDLLHandle,'HrGetOneProp');

see this documentation : https://social.msdn.microsoft.com/Forums/vstudio/en-US/8d283d08-00fa-4e84-a96a-61b226f526e2/outlook-2010-mapi-headers?forum=vsto

See attached correction. [MAPIUtil.pas](url
MAPIUtil.pas.txt
)
