IElementBehaviorFactory* pEBFactory = NULL;
//Create my com object of implementing IElementBehaviorFactory interface
CoCreateInstance(CLSID_Factory, NULL, CLSCTX_INPROC_SERVER,IID_IElementBehaviorFactory, (void**)&pEBFactory);
//Mashal IElementBehaviorFactory
hr = CoMarshalInterThreadInterfaceInStream(IID_IElementBehaviorFactory, pEBFactory, &pStm);
The return value hr is 0x80004002, why?

0x80004002 has the symbolic name E_NOINTERFACE.
IID_IElementBehaviorFactory : {3050F429-98B5-11CF-BB82-00AA00BDCE0B}
On the face of it the return value of E_NOINTERFACE seems not to make any sense. If the search of the IID in the registry however there is no proxy/stub registered; I'd guess that's the reason.

The default value of [HKEY_CLASSES_ROOT/Interface/{3050F429-98B5-11CF-BB82-00AA00BDCE0B}/ProxyStubClsid32] is {B8DA6310-E19B-11D0-933C-00A0C90DCAA9}.
{B8DA6310-E19B-11D0-933C-00A0C90DCAA9} is the class id of actxprxy.dll.
I think that actxprxy.dll is the proxy/stub for IElementBehaviorFactory, but I don't know why CoMarshalInterThreadInterfaceInStream call fail for IElementBehaviorFactory.

My system doesn't have this key. Yours does?

The environment is Visual Studio 2005 and my project was created via extensibility -> shared add-in.
How can I debug efficiently?
At present, I have to SETUP the add-in and start outlook manually each time I want to see the differences I have made to the program ...

A poor man's hack would be to insert __asm int 3 somewhere in the code. That will trigger windows into invoking a debugger. You will get a dialog asking you what to do: debug or quit. Choose debug, and use the running instance of VS.NET to debug. It's not pretty, but it works.
As for starting and quiting outlook: you'll have to learn to live with it. Outlook will lock your add-in dll while it's loaded, making it impossible to link the dll while it's running.

Using DebugBreak is the slightly more portable version. It does mean that the debugger stops inside the DebugBreak function rather than in the calling function, so you need to do a Step Out when the debugger stops.

I am trying to use the settings.designer.cs file for a value that needs to be put into the app.config file.
My config(auto-generated by VS2005) file now looks like this:-
<configuration>
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="Settings1" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</sectionGroup>
</configSections>
<applicationSettings>
<General.Settings1>
<setting name="DatabasePath" serializeAs="String">
<value>C:\Web\App_Data\Messages.mdb;</value>
</setting>
</General.Settings1>
</applicationSettings>
</configuration>
In the C# code i am trying to access this property by this code:
Settings1 set = Settings1.Default;
string str = set.DatabasePath;
return str;
The above line of code returns null.can anyone explain what am i missing here?

hi experts,
I'm quite new to the topic of COM and Automation and I have a few basic problems and questions:
I modified my existing MFC application to a multithreaded Automation server with the help of a tutorial i found on http://www.codeproject.com/com/mfc_autom.asp and made it via coinitializeex running as multithreaded, the application is a .exe
and lateron call COleTemplateServer::RegisterAll(),
but when I try to get an active instance via hr=GetActiveObject(clsid) I get as result: 0x800401e3 operation unavailable
and if i try to create a new instance via
hr=::CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IApplication1, (void**)&m_IApplication))
it returns the active instance instead of creating a new one
I also use another project with automation and there getactiveobject and cocreateinstance works fine
I think as COleTemplateServer::RegisterAll() returns TRUE it should correctly register my objects with the ROT (which if not, could be the reason for getactiveobject returning an error) or am I wrong?
So has anyone an idea how I become it working to getactiveobject() returning the active object and cocreateinstance() creating a new one 
with best regards Stefan Buchner

Hi guys,
This activex control has optionals parameters for GetData method:
this.axWinsock1.GetData(ref object data,object type,object maxlen)
i tried these:
object rec= string.Empty;
object type = 0;
object maxlen = 0;
this.winsock.GetData(ref rec, type, maxlen);
or
object rec= string.Empty;
object type = string.Empty;
object maxlen = string.Empty;
this.winsock.GetData(ref rec, type, maxlen);
but all i get is "Unsupported variant types" error message, do you know how to call this getdata method in c#? i know if you call it in vb.net you dont need to pas optional parameteres.
Please help

Don't use this control in C#. Instead, use the System.Net.Sockets.Socket class, or the TcpClient, UdpClient, TcpListener classes which are a little more friendly to use.
The data you get from the socket will be in raw bytes. You will need to use one of the System.Text.Encoding classes to turn text from the byte-oriented wire format into a string. As a starting point, try Encoding.Default.

well, there is a html file with this : ( I'll call it codez)
I want to do something before the someFunction() is called;
but,firstly,I must tell you that I only want to deal with the Event just when the onLoad is to be called,or being called. I don't want to deal with the event in DWebBrowserEvents2 with BeforeNavigate2 event,etc.
Following the MSDN, I found HTMLWindowEvents2, I thought DISPID_HTMLWINDOWEVENTS2_ONLOAD can be triggered when the codeZ is executed.But, disapointed, I can just get DISPID_HTMLWINDOWEVENTS2_ONUNLOAD and DISPID_HTMLWINDOWEVENTS2_ONBEFOREUNLOAD .
Whenever and Whatever html I visit,DISPID_HTMLWINDOWEVENTS2_ONLOAD is never received .
so. Can anybody help me???Maybe I should implements another interface??
Than you !!!!

Hi All,
I call a function fun()which is defined in X.dll .
the below is the code which is simillar to actual code.
when i execute i get as exception.
// sample.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "iostream.h"
#include "iomanip.h"
#include <algorithm>
#include <vector>
void fun(long **a);
int main(int argc, char* argv[])
{
long *amount = NULL;
fun(&amount);
long *ptr = amount;
for (int i = 0; i<5 ;++i,++ptr)
{
cout<< *ptr <<endl;
}
="" delete="" []amount;="" here="" i="" get="" an="" exception="" when="" try="" to="" delete.
="" return="" 0;
}
void="" fun(long="" **a)
{
="" *a="new" long[5];
=""
="" std::vector<long=""> var;
var.push_back(5);
var.push_back(6);
var.push_back(65);
var.push_back(58);
var.push_back(57);
std::vector<long>::iterator i;
int k = 0;
for(i= var.begin();i != var.end();++k, ++i)
{
(*a)[k] = *i;
}
}
the fun() is defined in the X.dll
Please let me know why i get an exception when i use delete []amount.
The same code works in the normal app, but when same mechanism is used in dll it does'nt work. the above code runs perfectly. i have the same code in the dll, the fun() is defined in the dll and the main() is in the application from which i use the interface to access the fun().
Thanks in advance..
Thanks & Regards,
Dhana

Why you are repositng same[^] question, asked few days back ? Doesn't that solve your problem ?
And what is there in this question related to COM?
|
|
|
|
|
Thanks for the solution and also to your concern..
Though that solved the problem..my actual problem is in the com component i am using. i thought i should put this question in the COM message board. i have given the exact scenario, the fun() is present in the COM Dll. If memory is allocated in the DLL using 'new' can i 'delete' the same in the application outside the dll?
Thanks & Regards,
Dhana

Its not COM dll, its simple dll.

Yes, but you are incrementing base address, and then deleting it.
Adopt method given in my previous solution to access the pointer.
