I'm stuck on the same thing right now. I think one option is to look up design patterns read up on the "Sender Observer Model" it will allow you to trigger a subroutine on the VB form and pass it arguements as well.
This will give you the same effect but it's not really answering the question I know. It is an alternative though.
Many Thanks,
Kiran

I have application developed in VC/COM/DCOM
At some point of time i got the following error message and application closed.
Faulting application <application name="">, version <version number="">, faulting module <module name="">, version <number>, fault address <hex address="">
Under what scenario does the above error occurs?

Hi All
I want to integrate an “.exe” program in my application (C# Application) but I don’t know how to do that!
The .exe program is a decryption program that needs a password to decrypt files.
Also if it’s possible that I send directly the output (decrypted file) into my application not into a file.
Regard.

Does this 3rd part app provide COM interop? If so, read it's documentation and do what it says.IF not, I'd suggest you look at the Process class. If you need anything beyond command line interfacing though you're SOL using it.

Hey everybody!!
I need to know if the Document property of the WebBowser control (used by Internet Explorer) returns also the DOM elements created dynamically via Javascript or just the static ones defined on the page.
If anybody knows something about this, or has used the control and can give a hint on this, I will really appreciate it. Any ideas are welcome.
Thanks in advance,
Best regards,
Kenia

Hi,
I am new to MAPI and exchange. I need to develop a plugin/server that can process all messages (of all users) on the server. I've seen examples where extensions are written and hosted in COM+ apps. However, I could not find any concrete examples written in C++.
I would appreciate it very much if someone can point me to any articles/examples that show how to hook onto exchange and perform operations at a global level.
Even if not on global level, atleast how to register for callbacks and get events on messages being read/moved/deleted/reply etc would be great.
Thanks in advance,
Cheers
Raja

Hi,
I've written a COM+ server in C# (VS 2005) which I can successfully use in both delphi and c# windows applications. However, I also have a c# windows application which has a plugin architecture whereby it creates a separate application domain in which the plugins are loaded and unloaded. The problem is, if one of the plugins uses the COM Server, although everything works fine, including the unloading and loading of the plugins, when I close the application I get and "Attempted to read or write protected memory" error during the OleUninitialize stage. The COM Server has been loaded and registered using regsvcs and regasm, and installed in to the GAC. The problem exists when using both early and late binding. Viewing the names of all the assemblies held in the separate application domain created by the program I can see the COM Server listed.
Hope this is enough information.
Any help would be appreciated.
Many thanks.

I have a COM project that builds fine in VS 2005 pro that I'm trying to migrate to 2008 pro. When the project links though, I get an MIDL2025 error when it tries to link an interface method that uses an exported structure. Is there something that changed between the two versions, or is there something else that I have to set in the build environment? Here's a snippet that shows what I'm dealing with:
[export,library_block]
struct MSG
{
DWORD dwMsg;
DWORD dwID;
};
// _IEvents
[
object,
uuid("B0EE4D4C-7153-4844-9907-CAAEB5F4B214"),
helpstring("_IEvents Interface"),
pointer_default(unique)
]
__interface _IEvents: IUnknown
{
[id(1), helpstring("method MessageEvent")] HRESULT MessageEvent([in] MSG m);
};

Hello, I am a beginner within the COM programming. After I have seen some simple examples of COM, I have a question about it.
Could any one tell me when using COM within a VC project, after compile and link, is there any difference with other common VC projects?
Many thanks

Currently my the process I'm going through for each change of the C# code in the COM object is the following. Is there anyway I can streamline the number of manual steps involved?
Close the Excel spreadsheet using the COM object.
Build the COM object using VS03.
Open the spread sheet.
Open VBA.
Open the references dialog.
Remove the Missing:myObject reference.
Close the references dialog.
Reopen the references dialog.
Add the MyObject reference.
Close the references dialog.
Run the VBA.

Aside from writing log files or spitting out mesageboxes can I debug a managed COM (C#) object being called from within a VBA (excel) application?

I've found I can open my test spreadsheet automatically when i start my VS project using the debug properties page of the project. I've found a new showstopper though. The moment I try and run the calling VBA macro in my spreadsheet it closes excel and ends my VS debugging session. The same thing happens if I have it launch excel without a document and then manual open it using that copy of excel.
If I open the spreadsheet in a separate excel window the macro runs and calls the COM object successfully but my breakpoints in the C# code are ignored.

Does VS03 need to write the registry every time a COM object is recompiled, or only the first time?

Check Post-Build event in your Project properties

THe post build event is empty. The registry fiddling is apparently being done elsewhere.

Do you build your project from within Visual Studio IDE or through any custom script (e.g batch script etc) ?

I tried creating a sample Project type : Other projects-extensibility projects-shared add in
By default, Post build event has -
regsvr32 /s /c "$(TargetPath)"
This will register adding every time you build. This is just a development time helper.

I have added a new interface to my activex control (ACEvt)
I have modified the odl file, and added the necessary BEGIN_INTERFACE_MAP, BEGIN_DISPATCH_MAP etc.... in the class implementation file.
//odl file
[ uuid(BED02315-567E-4a5d-A56B-5F00F228E041)]
dispinterface ICount
{
properties:
methods:
};
[ uuid(7C39BF1F-66DE-423e-B526-87626D80AE4D)]
coclass Count
{
[default] dispinterface ICount;
};
When I try to call CoCreateInstance and QueryInterface, i'm getting E_NOINTERFACE error.
IUnknown *pUnk = NULL;
HRESULT hr = CoCreateInstance(CLSID_ACEvt,NULL,CLSCTX_ALL,IID_IUnknown,(void **)&pUnk);
ICount *pCount = NULL;
hr = pEvt->QueryInterface(DIID_ICount,(void **)&pCount);
When I tried directly calling CoCreateInstance on Count, then I got "Class not registered error"
HRESULT hr = CoCreateInstance(CLSID_Count,NULL,CLSCTX_ALL,DIID_ICount,(void **)&pCount);
What might be the problem?
Thanks
