Attributes for Imported COM

[George Jeffcock]

Hello Community

Cant get a component package (Zetafax) to compile..

Firstly get this:

Starting Build of ZfLib14ZfLib14_pkg - Release
COMPILE : error C2039: 'IStream' : is not a member of 'ZfLib14'
                c:\lokalmodeller\comimpo20121\source\ZfLib14.h - Line 2481
COMPILE : error C2039: 'IStream' : is not a member of 'ZfLib14'
                c:\lokalmodeller\comimpo20121\source\ZfLib14.h - Line 2485
COMPILE : error C2039: 'ISequentialStream' : is not a member of 'ZfLib14'
                c:\lokalmodeller\comimpo20121\source\ZfLib14.h - Line 2544

Added a Attributes for Imported COM label

include( "IStream", "ISequentialStream","tagSTATSTG" )

It worked I did not get any C2039 errors again but a new set of errors:

Starting Build of ZfLib14ZfLib14_pkg - Release
COMPILE : error C2011: '_ULARGE_INTEGER' : 'union' type redefinition
                c:\lokalmodeller\comimpo20121\source\release\obj\zfapi32.tlh - Line 1327
COMPILE : error C2011: '_LARGE_INTEGER' : 'union' type redefinition
                c:\lokalmodeller\comimpo20121\source\release\obj\zfapi32.tlh - Line 1348

so with Compiler Error with #import Directive and the ADSI Type Library
this in mind have been trial and error and to be honest being impatient and not really understanding what is going on just hoping I will stumble accross the magic combination

Considering the header file looks like this now

#include "ObComFld.h"
#include "ObVariantFld.h"
#include "stdole20.h"
#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL>  \


raw_dispinterfaces  \


rename_namespace( "ZfLib14" ) \


include( "IStream", "ISequentialStream","tagSTATSTG" )

I have tried

#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL> rename("_LARGE_INTEGER", "")

 rename("_LARGE_INTEGER", "")

 rename("_LARGE_INTEGER", "("_LARGE_INTEGER2")

When Attributes for Imported COM label is set to (recommended in The #import Directive
) :

include( "IStream", "ISequentialStream","tagSTATSTG" ) \
rename( "_ULARGE_INTEGER", "_ULARGE_INTEGER2" ) \
rename( "_LARGE_INTEGER", "_LARGE_INTEGER2" )

I get the following compile errors that look that they might be https://support.ca.com/irj/portal/anonymous/kbproblem?productcd=CPLEX&problemnbr=1539 COM WRAPPER COMPILE ERROR C2664

but really must admit its hit and hope! Hopefully someone understands this..Jez.. :)

Many thanks

Is it because I have managed to import the DLL of zetafax and not the

"filename
Allows you to specify which type library you want to import. filename can be one of the following:
A type library (.tlb or .odl). file:, which indicates type library, can precede each filename. "

Only point this out to help the knowledgeable as really hit and hope for me at the moment[s]

A library (.dll) file containing a type library resource (such as .ocx). is allowed on import.

George,

Try

inject_statement("#undef _ULARGE_INTEGER") \
inject_statement("#undef _LARGE_INTEGER") \

instead of the rename

apologises for calling you out directly but you have been so helpful on the other posts.

Right my header file now looks like this after altering Attributes for Imported COM label as suggested.

#include "ObComFld.h"
#include "ObVariantFld.h"
#include "stdole20.h"
#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL>  \


raw_dispinterfaces  \


rename_namespace( "ZfLib14" ) \


include( "IStream", "ISequentialStream","tagSTATSTG" ) \
inject_statement("#undef _ULARGE_INTEGER") \
inject_statement("#undef _LARGE_INTEGER")

But the error C2011 are back:

Starting Build of ZfLib14ZfLib14_pkg - Release
COMPILE : error C2011: '_ULARGE_INTEGER' : 'union' type redefinition
                c:\lokalmodeller\comimpo20121\source\release\obj\zfapi32.tlh - Line 1334

Try

#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL> exclude("_LARGE_INTEGER", "")

error C2011 means 'LARGE_INTEGER' type is has been defined already.

Many thanks for helping out. a little bit of a puzzle.

#include "ObComFld.h"
#include "ObVariantFld.h"
#include "stdole20.h"
#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL>  \


raw_dispinterfaces  \


rename_namespace( "ZfLib14" ) \


include( "IStream", "ISequentialStream","tagSTATSTG" ) \
#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL> exclude("_LARGE_INTEGER", "") \
#import <C:\Program Files\Common Files\Equisys\ZFAPI32.DLL> exclude("_ULARGE_INTEGER", "")

And a new attribute 'exclude' and not 'rename' which I have tried and does get rid of the C2011 errors but leads to a new set (I used http://support.microsoft.com/kb/231271 as guidance)

Unfortunately exclude seems not to get rid of the C2011 errors

Starting Build of ZfLib14ZfLib14_pkg - Release

but will try new variations using this new attribute (new to me!)

OK, #undef wil not work as these are not macro definitions and so cannot be undefined.

Let's see if what I've sent you directly works (without crashing!)...

Jez managed to get it to compile!! I had to send the actual DLL in the end but here is the working compile solution for others to see. I personally would never had been able to do it through trial and error!

Ok George, lets see if this works – be prepared for it to crash your PC when run J.

The issue that I can see is that LARGEINTEGER and ULARGEINTEGER are referenced as structs in the type library header. Eg.

struct tagSTATSTG
{
LPWSTR pwcsName;
unsigned long Type;
struct ULARGEINTEGER2 cbSize;

but are defined as union in the Winnt.h when MIDL_PASS is not defined.

#if defined(MIDL_PASS)
typedef struct LARGEINTEGER {
#else // MIDL_PASS
typedef union LARGEINTEGER {
struct {
DWORD LowPart;
LONG HighPart;
};
struct {
DWORD LowPart;
LONG HighPart;
} u;
#endif //MIDL_PASS
LONGLONG QuadPart;
} LARGE_INTEGER;

In the model ZfLib14._LARGE_INTEGER matches the structure definition.

This is how I’ve got it to compile…

In the model, rename ZfLib14._LARGE_INTEGER to ZfLib14._LARGE_INTEGER2 and ZfLib14._ULARGE_INTEGER to ZfLib14._ULARGE_INTEGER2. This is so the cpp file contains the correct names

Set your attributes label to the following:
include( "IStream", "ISequentialStream","tagSTATSTG" ) \
inject_statement("typedef struct _LARGE_INTEGER2 { LONGLONG QuadPart; } LARGE_INTEGER2;") \
inject_statement("typedef struct _ULARGE_INTEGER2 { ULONGLONG QuadPart;} ULARGE_INTEGER2;") \
rename("_LARGE_INTEGER", " _LARGE_INTEGER2") \
rename("_ULARGE_INTEGER", "_ULARGE_INTEGER2")

This provides the the definition of our structures and the rename to ensure thye are used in the package.
This all builds cleanly, but the real proof will be if ti runs without crashing.
Kind Regards,
Jeremy Hutchinson


So in the end it invloved renaming objects in the plex model also, but I peronally think this import of coms is great even if it is a pain to get some packages to compile, i mangaged to get 3 or four previous packages to build but this defeated me so many thanks Jez, how about 50 quid a package Jez!
