I don't think its quite that simple.
You are venturing into the realms of COM (of which I am still a student), and not just any common DLL.

Unlike LoadLibrary() that loads a regular dll into your address space, and therefore enabling you to execute its functions; 'instantiating' a component interface, which is what your sample does, does not involve the same concept.

at least thats what I think what you are asking!

My next question was about the LoadLibrary(...) func.

I guess thats the one I should use.

_ContactItemPtr pContact;
CComVariant vIndex;

m_spApp->GetNamespace(_bstr_t("MAPI"),&pNamespace);
// select the default outlook contacts folder
pNamespace->GetDefaultFolder(olFolderContacts,&pFolder);
pFolder->get_Items(&pItems);
Outlook::OlObjectClass Class;
CComBSTR EntryId;
pItems->get_Class(&Class);
// iterate the list
hr=pItems->GetFirst((IDispatch**)&pContact);
while ((hr==S_OK) && (pContact!=NULL))
{
    pContact->get_Class(&Class);
    if (Class==olContact)

problem adding new interface method

Hi and thank you for chyecking my post.

I have added a new method to the interface of an existing COM+ component. The component (dll) runs as a library (runs in the creator's process). The trouble is that the the new method is not being picked up and added to the interface.

Here is what I do :-

- I build the dll
- stop the IIS Out of Process on the server
- copy over the dll and fire up an ASP page
- I then check Component Services to see if the new method has been added to the interface. It has NOT.

I know I am missing something but what is it? I'm relatively new to COM.

Thanks for any help.

Mike

You can using TypeLib Viewer to make sure that the method is added to the interface.If it's does exist,may be you should create a new com+ server using the new dll.I think the interface you seen in Component Services is the old one.

CoRegisterClassObject

14-Jun-04 8:38

According to MSDN: Only EXE object applications call CoRegisterClassObject. Object handlers or DLL object applications do not call this function &emdash; instead, they must implement and export the DllGetClassObject function.

But why CLSCTX_INPROC_SERVER there??? It says it is for DLL, but CoRegisterClassObject says for EXE??

Thanks a lot for replying

CoRegisterClassObject "Registers an EXE class object with OLE so other applications can connect to it. EXE object applications should call CoRegisterClassObject on startup. It can also be used to register internal objects for use by the same EXE or other code (such as DLLs) that the EXE uses."

CLSCTX_INPROC_SERVER could be used to register an object for internal use by an executable.

You'd basically create such an object the same way you do any normal COM object, using CoCreateInstance. There's a small simple ATL COM example on CodeGuru. Google's also a good place to start.

How to Create a COM object from a nominated EXE

Guy le Mar8-Jun-04 15:51

Guy le Mar

8-Jun-04 15:51

It's possible to use LoadLibrary() and GetProcAddress("DllGetClassObject") on a DLL in order to obtain a ClassFactory. You can then use the ClassFactory to create a COM object.

Is there is an equivalent technique that can be used for an EXE?
That is, can I create a COM object from a nominated instance of an EXE?

Thanks in advance.

Passing BSTR and Short variables in a function

Hi,
I have a function that passes the following arguments:

void SignOn(BSTR* Name, BSTR* Password, BOOL* UseProxy, BSTR*
ProxyServer, short* ProxyPort);.

I declared the following variables which I pass to the function

BSTR Name = ::SysAllocString(L"coinpig");
BSTR Password = ::SysAllocString(L"aug2203");
BOOL useproxy = 0;
BSTR proxyServer = ::SysAllocString(L"0");
short ProxyPort = 0;
short * strPortptr = &ProxyPort;

When I use the active-x control test container and specify that all
values are BSTR the function works properly. When I call the function
with the variables I declared, the program exits with code 3. I am
new to MFC, and greatly appreciate any help.

Thank you,
Tom

How are you calling the SignOn function in your code?

To call SignOn with the variables you have created and the function prototype you have given:

<code>
SignOn(&Name, &Password, &useProxy, &proxyServer, strPortptr);

Or you could prototype your function like:

<code>
void SignOn(BSTR Name, BSTR Password, BOOL UseProxy, BSTR ProxyServer, short ProxyPort);

and then call the function:

<code>
SignOn(Name, Password, UseProxy, ProxyServer, ProxyPort)

The only difference between the two: the former uses pointers as parameters, whereas the latter does not.

I prefer the second approach unless I need to logically change the value of more than one variable in which case I would change my parameters to use pointers. Functions can only have one physical return value.

Hope this helps!

Download my .ocx and 2 depending dll’s?

anderslundsgard6-Jun-04 21:02

anderslundsgard

6-Jun-04 21:02

Hi,
I’m developing an ActiveX-control in VS C++ 6.0 (WinXP): works fine.
For deployment, I’m using VS.NET for making the Cab-file (New project: Cab
Project). Adds ocx and builds Cab: works fine.

Problem: The .ocx is depending on 2 other dlls, as it is now they are downloaded and registered manually: this works some times, some times it is "Dll Hell".... "Dll hell" occurs when updating ocx and dlls.... is there any way to force registration and so on? My belive is that it will work fine if I just adds the dll to the Cab File-project, could that be right? If so, how do I do it in VS.NET (I know how to add the files, but it’s not working when adding the depending dlls)?

I’m also a bit confused of the making of the Cab File, with VS.NET (Cab Project, OSD-file) it’s easy, but I don’t know what I’m doing... old tech, with INF-file, it was harder, but more open I guess?

Which is the best solution in my case? Confused | :confused:

Hi Lokesh,

Not too sure what you are after but here I've done an example that may be what you are looking for:

MSHTML::IHTMLDocument2Ptr spDoc(m_ctlWeb1.GetDocument());
if (spDoc)
{
    MSHTML::IHTMLDocument3Ptr spDoc3 = spDoc;
    if (spDoc3)
    {
        MSHTML::IHTMLElementPtr spElem = spDoc3->getElementById(_bstr_t("idSpan1"));
        if (spElem)
        {
            spElem->innerText = _bstr_t("Hello There");
            MSHTML::IHTMLStylePtr spElemStyle = spElem->style;
            if (spElemStyle)
            {
                spElemStyle->textDecorationOverline = true;
            }
        }
    }
}

So in the code above we look for an element called 'idSpan1', set the text, and then set the text decoration style to be Overline. Hope this is near the mark.

For further style information go to MSDN and look at the following interfaces:

IHTMLStyle
IHTMLStyle2
IHTMLStyle3
IHTMLStyle4

Hope this helps,
Andy

How to call methods of an appobject directly?

Roozbeh693-Jun-04 18:32

3-Jun-04 18:32

Hello everybody,

I am a beginner in com programming, and i have a question:
I have created an ATL 3.0 project including a simple object named MyObj with the attribute of 'appobject' on it's coclass. It has a property named MyString that holds string values. I have successfully built it and then tested it from vb. I have access to MyString property directly without instantiating MyObj. everythings is Ok.
but I have problem with VC. From a Console application which has access to that type library (via import directive) MyString property cannot be accessed without qualification. With the statement:

MyString = "Hello world!";

compiler generates following error:

error C2065: 'MyString' : undeclared identifier

what is the problem? do you think i should use a special syntax?
if so, would you please help me to know how i can use it?

thanks in advance
Roozbeh
