How to read .ocx file in C++ (Not MFC)

Hi,

I have an existing .ocx file which contains a map. I need to open this file in C++ and not in MFC. MSDN help suggested me that it can be done throuch " #import "file_name" " However, the description is not descriptive and helpful. If anyone can provide me some ideas or sample code to read this file would be greatful.

Hope someone will give reply to this :-)

Thanks & regards,
Swetha

a #import directive like
#import "<name of the ocx file or typelibrary>" no_namespace, raw_interfaces_only \
named_guids raw_native_types <any other #import attributes>
will generate a header file with the name <base name of tlb/ocx>.tlh. and this header is impliciltly #included.
the #import attributes specify options for generating the header file. this header contains C++ definitions of COM interfaces, types etc and can be directly used in your code.
instantiate the object using a CoCreateInstance. COM methods are seen by C++ as virtual functions. open the .tlh file to see the declarations and use the methods like normal virtual functions. once you are done, call Release instead of using delete.

Hi,

Thanku very much for giving quick reply.
Actually I am very new to c++.So now I am having .ocx file.
Using #import "filename" ?I am trying to read that file.If I use #import directive it created *.tlh and .tli files.But it is giving some errors while using CoCreateInstandce function.
If you dont mind can any one send some simple sample code related to this?
Or where to call this CoCreateInstance function and which parameters need to give?

I hope will give reply as early as possible.

Thanks And Regards,
swetha.

Hi vijayan,
Thanks a lot for ur prompt response.I will try tomarrow.

The .ocx file contains the map.So I need to read that file and display that map.I think using ur code I can achieve this one.

Thanks And Regards,
swetha.

Hi vijayan,

How did you define "IID_IiTunesDetector" variable in your header file? I tried defining this variable from all possible ways .However, while compiling I am getting error as unexpected identifier for this variable.

Following is my code.
//////////////////////////////////////////////////
C++ Syntax (Toggle Plain Text) 
  1. #import "c:\WINNT\system32\mmap.ocx"
  2. int main()
  3. {
  4. CoInitialize(NULL);
  5.  _DMMap* pMP = 0;
  6. HRESULT hr = CoCreateInstane(CLSID_DMMap,0,CLSCTX_ALL,IID_DMMap,reinterpret_cast  <void**>(&pMP));
  7. .........
  8. .........
  9. CoUninitialize();
  10. }
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

I think u got my doubt.Can you clarify and send the sollution?Hope u will send the reply.

Thanks in Advance,
swetha.

> How did you define "IID_IiTunesDetector" variable in your header file?
it was defined for me in the generated .tlh header due to the presence
of the named_guids attribute in the #import directive

this is (an extract from) the .tlh header generated:
C++ Syntax (Toggle Plain Text) 
  1. // ...
  2. // Forward references and typedefs
  3. struct __declspec(uuid("d6995525-b33a-4980-a106-9df58570cc66"))
  4. /* LIBID */ __ITDETECTORLib;
  5. struct /* coclass */ iTunesDetector;
  6. struct __declspec(uuid("45d2c838-0137-4e6a-aa3b-d39b4a1a1a28"))
  7. /* dual interface */ IiTunesDetector;
  8.  
  9. // Type library items
  10. struct __declspec(uuid("d719897a-b07a-4c0c-aea9-9b663a28dfcb"))
  11. iTunesDetector;
  12.     // [ default ] interface IiTunesDetector
  13.  
  14. struct __declspec(uuid("45d2c838-0137-4e6a-aa3b-d39b4a1a1a28"))
  15. IiTunesDetector : IDispatch
  16. {
  17.     // Raw methods provided by interface
  18.     // ...
  19.       virtual HRESULT __stdcall get_iTunesVersion (
  20.         /*[out,retval]*/ long * pVal ) = 0;
  21.     // ...
  22. };
  23.  
  24. // Named GUID constants initializations
  25. extern "C" const GUID __declspec(selectany) LIBID_ITDETECTORLib =
  26.     {0xd6995525,0xb33a,0x4980,{0xa1,0x06,0x9d,0xf5,0x85,0x70,0xcc,0x66}};
  27. extern "C" const GUID __declspec(selectany) CLSID_iTunesDetector =
  28.     {0xd719897a,0xb07a,0x4c0c,{0xae,0xa9,0x9b,0x66,0x3a,0x28,0xdf,0xcb}};
  29. extern "C" const GUID __declspec(selectany) IID_IiTunesDetector =
  30.     {0x45d2c838,0x0137,0x4e6a,{0xaa,0x3b,0xd3,0x9b,0x4a,0x1a,0x1a,0x28}};
  31. // ...

so i could use the named constants as in
C++ Syntax (Toggle Plain Text) 
  1. CoCreateInstance( CLSID_iTunesDetector, 0, 
  2.                     CLSCTX_ALL,
  3.                     IID_IiTunesDetector,
  4.                     reinterpret_cast<void**>(&pitd) ) ;

alternatively i could have written
C++ Syntax (Toggle Plain Text) 
  1. CoCreateInstance( __uuidof(iTunesDetector), 0, 
  2.                     CLSCTX_ALL,
  3.                     __uuidof(IiTunesDetector),
  4.                     reinterpret_cast<void**>(&pitd) ) ;
this would not require generation of named guid constants.

if you want to generate named guid constants, use named_guids attribute in the #import directive
C++ Syntax (Toggle Plain Text) 
  1. #import "c:\WINNT\system32\mmap.ocx" named_guids no_namespace
without the no_namespace attribute for the #import,
all names imported would be inside a namespace (with the base name of the typelib).

or else use the __uuidof operator
in your case the uuid for the interface would be given by __uuidof( _DMMap )
in all cases, look in the generated .tlh file to get the correct identifiers.
eg. if you see struct /* coclass */ <name of class> ; in the header,
for the CLSID you should use __uuidof( <name of class> )

you don't know anything about using COM in C++, do you?
even if you get to somehow do this part now, you are going to face more problems
somewhere else sooner rather than later. perhaps you should take some time to
first read http://www.amazon.com/Inside-Microso.../dp/1572313498
and then http://www.amazon.com/Essential-COM-.../dp/0201634465

Hi vijayan,

this is (an extract from) my "MMap.tlh" header generated:
C++ Syntax (Toggle Plain Text) 
  1. /////////.........................................///////////
  2.  
  3. struct __declspec(uuid("d5f63c22-b3d3-11d0-b8f0-0020af344e0a"))

  19. _DMMap : IDispatch
  20. {
  21.     //
  22.     // Property data
  23.     //
  24.  
  25.     __declspec(property(get=GetMapNorth,put=PutMapNorth))
  26.     double MapNorth;
  27.     __declspec(property(get=GetMapSouth,put=PutMapSouth))
  28.     double MapSouth;
  29.     __declspec(property(get=GetMapEast,put=PutMapEast))
  30.     double MapEast;
  31. ......
  32. ......
  33. ......
  34. };
  35. struct __declspec(uuid("d5f63c23-b3d3-11d0-b8f0-0020af344e0a"))
  36. _DMMapEvents : IDispatch
  37. {

  47.   .....
  48.   ......
  49.   .....
  50. };
  51. struct __declspec(uuid("d5f63c24-b3d3-11d0-b8f0-0020af344e0a"))
  52. MMap;
  53. // [ default ] dispinterface _DMMap
  54.     // [ default, source ] dispinterface _DMMapEvents
  55. //
  56. // Named GUID constants initializations
  57. //
  58.  
  59. extern "C" const GUID __declspec(selectany) LIBID_MMAPLib =
  60.     {0xd5f63c21,0xb3d3,0x11d0,{0xb8,0xf0,0x00,0x20,0xaf,0x34,0x4e,0x0a}};
  61. extern "C" const GUID __declspec(selectany) DIID__DMMap =
  62.     {0xd5f63c22,0xb3d3,0x11d0,{0xb8,0xf0,0x00,0x20,0xaf,0x34,0x4e,0x0a}};
  63. extern "C" const GUID __declspec(selectany) DIID__DMMapEvents =
  64.     {0xd5f63c23,0xb3d3,0x11d0,{0xb8,0xf0,0x00,0x20,0xaf,0x34,0x4e,0x0a}};
  65. extern "C" const GUID __declspec(selectany) CLSID_MMap =
  66.     {0xd5f63c24,0xb3d3,0x11d0,{0xb8,0xf0,0x00,0x20,0xaf,0x34,0x4e,0x0a}};

so now I am using the named constants as
C++ Syntax (Toggle Plain Text) 
  1. ///mmap.cpp
  2. #import "c:\WINNT\system32\MMap.ocx" 
  3.  
  4. void  main()
  5. {
  6. 	CoInitialize( NULL);
  7.  
  8. 		_DMMap* pMP = 0;
  9. 		HRESULT hr  = CoCreateInstance( __uuidof(MMap), 
  10. 					  NULL,
  11. 					  CLSCTX_ALL,
  12. 					  IID_DMMap,     
  13. 					  reinterpret_cast <void**>(&pMP));  
  14. 		assert(SUCCEEDED(hr));
  15. 		hr	= pMP->GetMapID();
  16. 		assert(SUCCEEDED(hr));
  17. 		pMP ->Release();
  18. 	  CoUninitialize();
  19. }
But while compiling error is getting errors like
'MMap' :undeclared identifier
_DMMap' : no GUID has been associated with this object

Actually I am not having idea about COM in C++. Surely I will see those links and I will try to learn about this.

Please tell me what I did wrong?Or you tell me how u r generating named guid constants using # import directive?

Thankyou very much for ur prompt reply.



Thanks in advance,
swetha.

> But while compiling error is getting errors like 'MMap' :undeclared identifier
looks like you have not used the no_namespace attribute; so the identifiers are in a namespace in the .tlh
also looks like you have not read my previous post or if you have read it, you haven't understood it.

in any case, to avoid getting into what in programming would be called an infinite loop, post the entire contents of the generated .tlh file. also the actual #import statement that you used.
on second thoughts, don't post it; just attach it to your post as a plain text file. that way, we would not have to contend with the intricacies of using code tags and the perversities indulged in by aniweb's code formatter and the preview facility provided.
