Hi All,
I am trying to Implement a "Simple Object" interface through ATL Object Wizard. But i am wondering there is no option of
IObjectWithSite (IE object support) in the ATL Object Wizard dialog, I am using VC6.0.
Is this option avaiable only with VC7.0 because i know lot of people talk about that, also MSDN doc listed this interface in the
support list for simple object.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/vcurfattributesatlsimpleobjectwizard.asp[^]
Also I have another question.
If i derived a interface from two interfaces (IObjectWithSite ) and (IDocHostUIHandler). the complier gives me following
error
I have following code
<br />
class ATL_NO_VTABLE CtempInterface : <br />
public CComObjectRootEx<CComSingleThreadModel>,<br />
public CComCoClass<CtempInterface, &CLSID_tempInterface>,<br />
public IConnectionPointContainerImpl<CtempInterface>,<br />
public IDispatchImpl<ItempInterface, &IID_ItempInterface, &LIBID_TESTTHISLib>,<br />
public IDocHostUIHandler
{<br />
};<br />
c:\program files\microsoft visual studio\vc98\atl\include\atlcom.h(1827) : error C2259: 'CComObject<class ctempinterface="">' : cannot instantiate abstract class due to following members:
c:\program files\microsoft visual studio\vc98\atl\include\atlcom.h(1823) : while compiling class-template member function 'long __stdcall ATL::CComCreator<class atl::ccomobject<class="" ctempinterface=""> >::CreateInstance(void *,const struct _GUI
D &,void ** )'
Can anyone help me?
Thanks

It means you have not implemented at least one of the interfaces member functions. If you have done that already, make sure your functions share the same type signature as defined in the interface. Remember that void function(int x) is not the same function as void function(long x).
The compiler should tell you which function that aren't implemented. Look closer at the error output.

Havent we had enough of this abomination? I have ceased to use ATL for my components. (As if this was not enough, along comes ATL server).

I certainly haven't. Was it too hard for you to understand how it works?

ATL is more than a beauty!!! I hope you must take rest for 2-3 days and come back on your codes, this happens usually when we dont get results , EITHER ourself or on CP!!!

with respect to my previous query, i decided to use the WMPplayer control to implement the server-client. that will mean that the activeX control will be passed as a parameter from the client to the ATL COM server interface. Now i have problem compiling the IDL file generated by the ATL wizard because of the the activeX control parameter. what files or lib must i #include or import to make the compiling of the IDL file possible? i ever tried using ADO and i needed to include the msado.dll file. thanks. would be great if anyone can direct me a book or website which lists such information for my ease in future.... thanks a million in advance.

Hi!
With CreateFromFile() I am able to open an excel file in my ole
container application.
I want to embed excel sheet in my container applicatio and want to
display contents of a file, but i dont want to use CreateFromFile(), I
just want to pass raw data as input.
Which function shall I use,CreateFromClipboard() or CreateFromData().
I am running in Win2k and have office2k.
Thanks
Anshu

You are talking about MFC functions, right ?
If you want to paste object from clipboard then use CreateFromClipboard, otherwise CreateFromData.
All the CreateFromClipboard is doing is getting data object from the clipboard and passing it to "CreateFromData".

Thanks for the response.
Yes I am talking about mfc functions.
What I want to do is,display the .xls file in the container without using CreateFromFile().I want to read the file with CreateFile() and then send that data to display in the container.I hope u got my problem.

Hi everybody,
How do I support COM+ services (not the old version, MTS) in an ATL 3.0 project?
I don't plan to use ATL 7.0 or Visual Studio .NET.
Regards,
Roozbeh.
Dear friends!
I mean which libraries, I must include in my project. for example when you create an ATL 3.0 project with the server type of 'Dynamic Link Library' you have the 'Support MTS' option and choosing it, causes to include proper libraries in the project. But I want to include new COM+ libraries instead of the old version MTS libraries.
thanks.

When you say 3.0, I assume you mean VC6?
Should be no problem. You can optionally implement additional interfaces like IObjectConstruct etc so you can see things like constructor strings, but it's not really any more difficult than writing COM components. However, you might want to look closely at your design, to see where you can benefit from stateless objects and JIT activation.

(I dunno, these people that edit questions afterwards...)
AFAICR, 'use MTS' just adds some mts related libs (mtx,mtxguid and a delayload for mtxex.dll), does an mtxrereg of your DLL after a build.
I believe MTS only supports apartment threading, but someone who knows these things will be along to correct me in a while), whereas COM+ can handle free threaded stuff quite happily, and in fact, apartment threading will cause bottlenecks.
There are no libs per se (and yes, where I am, we have lots of COM+ stuff written using VS6...)

I want to expose a user defined data type (struct) to clients using ATL. I also wanted this struct to be a parameter to one of my methods. Is there a way in which I could do this?
SDE

If your class is foo and the structure is public or accessible to the calling object:
class foo
{
public:
struct myStruct
{
int a;
int b;
} myStruct;
void UseFooStruct(myStruct s);
}
class bar
{
public:
void UseFooStruct(foo::myStruct s);
}
|

|

I think I must have phrased it wrong. I know what you mean. But what I wanted is to expose the struct to one of my interfaces, then be able to pass the struct from Visual basic to My VC++ COM object. Is this possible?
SDE
|
|
|
|

Yes. You can define a user defined structure (a Type) in VB which corresponds to your C++ structure. That way, you can pass the structure back and forth. Look in the MSDN on how to do this: Passing User-Defined Types to a DLL Procedure. Of course, your Type declaration in VB must be equivalent to the C++ version.

Hi all,
Wondering if anyone knows why I'm getting this error when i try to build certain DirectShow samples from the DX9SDK. Here's what i get compiling a debug
<br />
------ Build started: Project: PlayWnd, Configuration: Debug Win32 ------<br />
<br />
Linking...<br />
playwnd.obj : error LNK2019: unresolved external symbol "long __stdcall ATL::AtlWinModuleInit(struct ATL::_ATL_WIN_MODULE70 *)" (?AtlWinModuleInit@ATL@@YGJPAU_ATL_WIN_MODULE70@1@@Z) referenced in function "public: __thiscall ATL::CAtlWinModule::CAtlWinModule(void)" (??0CAtlWinModule@ATL@@QAE@XZ)<br />

.\Debug/PlayWnd.exe : fatal error LNK1120: 2 unresolved externals<br />
There are certain samples (with names ending in ASF) that require the Windows Media SDK and a certificate. But PlayWnd isn't one of them. (PlayWndASF is.)
I'm working on a full screen video player, the other relevant samples that play video also give me the same error. "Windowless" for example.
I know it's something stupid...

This is using ATL7.0, I assume.
Is the source from an MS sample? It may be that it was originally written to use ATL3, and you need to make some (hopefully) minor changes.
What's your ATL specific set of includes?
Steve S

It's the PlayWnd sample as found in \DX90SDK\Samples\C++\DirectShow\Players\PlayWnd. I'm using VC7 (.NET 2003) so i assume it's ATL 7? Dunno, i've been away from this stuff for a few years...

I am trying to write a Browser Helper Object, but I am having a problem making it recognisable as a BHO. Following the instructions in Dino Esposito's MSDN article, using VC++6 I generate a standard ATL Com AppWizard project, selecting .DLL as the server type. I then insert an ATL Object, selecting an Internet Explorer Object, leaving all the defaults (appartment threading, dual interface, aggregation, no errorInfo, Connection Points or Free Threaded Marshaller). I then simply add the extra registration into the .RGS file to put the CLSID into HKLM|software|microsoft|windows|Current Version|explorer|Browser Helper Objects. I do not add any extra code, but just build the project. It registers OK, and the CLSID appears in the registry as expected. However, when I run BHODemon (www.definitivesolutions.com), it does not see the new helper, nor, as far as I can tell, does Internet Explorer. I have compared my software with working BHOs such as IEhelper and Dino Esposito's HTMLEdit, but can find nothing to explain my difficulty. Can anyone help?
Dave

You know that in the RGS file there are 2 CLSID's right? Did you select the correct one?
