Alexander,
I found the solution to my problem. After digging through the VS.Net
documentation I found the [export] directive which can be placed on the line
above the enum definition in the class header file. The export directive
causes the enum statement to be inserted into the generated idl file making
everyone happy.
Here's what it looks like.
[export]
typedef [helpstring("SessionStatus Enumeration")] enum SessionStatus {
cmInactiveSession = 0,
cmActiveSession = 1
Quote:
} SessionStatus;
// ICMSession
[
object,
uuid("44F0647C-BD90-463F-AC03-47B0B7EFE85D"),
oleautomation, helpstring("ICMSession Interface"),
pointer_default(unique)
]
__interface ICMSession : IUnknown
{
[propget, helpstring("property hSession")] HRESULT hSession([out, retval]
LONG* pVal);
[id(1), helpstring("method Logon")] HRESULT Logon([in] BSTR ServerName,
[in] BSTR UserID, [in] BSTR Password);
[id(2), helpstring("method Logoff")] HRESULT Logoff(void);
[propget, helpstring("property Status")] HRESULT Status([out, retval]
SessionStatus* pVal);
[propput, helpstring("property Status")] HRESULT Status([in] SessionStatus
newVal);
Quote:
};
And the resulting idl looks like...
typedef [
helpstring("SessionStatus Enumeration")
]
#line 7 "c:\\my programs\\vc7\\rcmx7\\rcmx7\\cmsession.h"
enum SessionStatus {
cmInactiveSession = 0,
cmActiveSession = 1,
Quote:
} SessionStatus;
[
object,
uuid(44F0647C-BD90-463F-AC03-47B0B7EFE85D),
oleautomation,
helpstring("ICMSession Interface"),
pointer_default(unique)
]
#line 19 "c:\\my programs\\vc7\\rcmx7\\rcmx7\\cmsession.h"
interface ICMSession : IUnknown {
#line 21 "c:\\my programs\\vc7\\rcmx7\\rcmx7\\cmsession.h"
[propget,helpstring("property hSession")] HRESULT hSession([out,retval]
LONG *pVal);
[id(1),helpstring("method Logon")] HRESULT Logon([in] BSTR ServerName,
[in] BSTR UserID, [in] BSTR Password);
[id(2),helpstring("method Logoff")] HRESULT Logoff();
[propget,helpstring("property Status")] HRESULT Status([out,retval] enum
SessionStatus *pVal);
[propput,helpstring("property Status")] HRESULT Status([in] enum
SessionStatus newVal);
Quote:
};
Before using the export directive the enum SessionStatus would not even show
up in the idl file which then generated the MIDL error.

typedef enum syntax changed in VS.Net C++ ATL?
