I have a COM library project and now would like to pass an INT64 argument in an interface method.
When compiling the IDL however I get ...Any suggestion ?Quote:

It should be LONGLONG
Thx for the hint but when using LONGLONG I getThe code in IDL isCode:warning MIDL2039 : interface does not conform to [oleautomation] attribute
Code:[id(5), helpstring("method ParamTest")] HRESULT ParamTest([in] LONGLONG n64Input, [out] int* pResult);
Tested the following:
Built with max error/warning level. Got not a single warning of the kind:Code:#include "olectl.h"

Maybe the key point is VS version? :)
A wild guess: did you ever apply any VS6 servicepack?
That's VS6 and if I remember well SP6 but can't find that in the about box :ehh:
VS6 "About box" does not contain any SP info.Quote:

And did you install some SDK for VS6 (the last one was from Feb. 2003)?
Thx for the registry hint ! It tells me I indeed installed SP6.
SDKs for VS6 ? None I think ... can I also check that in registry ?
The only SDKs I have installed are 2.0 for .Net and 6.0A for Windows
but those are not relevant for this problem I presume.
Yes.Quote:

Exactly the 2 SDKs that I mentioned.
Am I missing a crucial SDK for getting my IDL to compile correctly ?
Another key point: warning is not an error. :)
I've just checked it with VS6, it generates .tlb and proxy code alright (disregarding the warning). And with all subsequent VS versions it compiles just fine. :)
Despite the warning, I can now indeed pass 64bit values between COM dll and client app :)
Just 1 more question about the oleautomation attribute for the interface.
By just saying the interface is automation compatible, it doesn't actually make it so, right ?
Thx all :thumb:
oleautomation attribute
And yes, it's just an indicator. BTW, to fully comply with oleautomation you'd better go with VARIANT rather than LONGLONG.
Been looking into that, but couldn't quite figure out how to use VARIANTs for 64bit :blush:
Will investigate this suggestion further !
http://msdn.microsoft.com/en-us/library/ms221627.aspx
There are the membersQuote:
Code:LONGLONG llval; // VT_I8
LONGLONG * pllVal; // VT_BYREF|VT_I8
ULONGLONG ullVal; // VT_UI8
...
I would say, llVal. :)
That would have been too easy ! I'm using VS6 and llVal is not defined in my oaidl.h :cry:
That's more or less what I meant with;)Quote:
Been looking into that ...
Then find and download the Platform SDK from Feb. 2003.
