Hi,
I am trying to hook into this HTMLWindow event.
Here is what I am doing :
In MyHandler class :
COM_INTERFACE_ENTRY_IID(DIID_HTMLWindowEvents2, IDispatch)
virtual HRESULT __stdcall onunload(IHTMLEventObj* pEvtObj) { ... }
STDMETHODIMP DocumentComplete(IDispatch *disp,
VARIANT *url) {
....
HRESULT hr = S_OK;
LPDISPATCH doc_disp = NULL;
CComQIPtr<ihtmldocument2> doc;
hr = browser->get_Document(&doc_disp);
doc = doc_disp;
....
SomeOtherFunc1(doc);
}
void SomeOtherFunc1(IHTMLDocument2* doc) {
CComQIPtr<ihtmlwindow2> wnd;
hr = doc->get_parentWindow(&wnd);
SomeOtherFunc 2(wnd);
}
void SomeOtherFunc 2(IHTMLWindow2* wnd) {
AtlAdvise( wnd, (IDispatch*)this,
DIID_HTMLWindowEvents2, &cookie);
}
The handler class is already hooking into DWebBrowserEvents2 and all the handlers get called (DocumentComplete among them).
And I added similar code for the HTMLWindowEvents2.
AtlAdvise returns S_OK and inside it finds the CPC and the CP and Advise returns success and a valid cookie.
But onunload is not called when I navigate away from a page.
The module is a BHO dll loaded by IE.
I believe the HTMLWindowEvents2 interface is dual so I should be able to use VTBL events, right ?
Am I missing something here ?

Thank you!

Hi,
I'm writing a COM interop interface in C# (VS2005) to be used in VC++, and got into problem of proper exporting enum-s in such interface.
When i previously used C++ for writing COM interfaces, i would just declare the enum within IDL file, and then within the library section also declare it, that way way making my enum accessible when TLB file is imported using #import in C++;
Now in C# if i declare: public enum MyEnymType {val1, val2,...}, then such object when imported into C++ project is declared as: enum MyEnymType {MyEnymType_val1, MyEnymType_val2,...} instead of enum MyEnymType {val1, val2,...}
Is there a way to make C# embed my enum type into the object in such a way that it exports original enum declaration during import instead of such an ugly Type_Value thing?
Thank you,
Vitaly

My question is on C# and COM at the same time - which is the right place to post then, if not in both C# and COM forums?....

It is normal to post them on one forum. Pick the one that you think is most appropriate and then post it there. In this case, it is more relevant to the C# forum because that is where you want to override the enum.

Sir,
I have a third party component, which has displaying graphical chart functionality. This chart functionality is implemented as a part of coClass and an interface is provided to user. Using this interface i need to access the methods and properties of component. Could you throw some light on how to attach this component class to ole containers document window at runtime.
I have used coCreateInstance to create the class, but i want to know how can i attach this class to CWnd(window) class at runtime. so that i can get chart displayed at runtime in document window.
Thanks in advance.

Probably you need to use OleCreate if I am understanding you correctly. For OleCreate you need to have an OleDocumentContainer in which you will host the control.
Look at the help of OleCreate in MSDN and tell me if you get any problem.

(1) The HARD side: You need a RS232 Null-modem or cross over cable.
(2) The SOFT side: It depends on the software env you're using.
(e.g. you can use Windows API such as ReadFile or the COM control MsComm).
Hope that helps.

It depends on the language (and libraries) you intend to use.
I wrote:
(1) VB6 applications using MsComm control.
(2) C++ ones using the Win32 API (CreateFile(), ReadFile(), WriteFile().
the (1) are fairly simpler, 'cause the (2) are much more low level (and usually you've to deal with threads.
Of course you can also use MsComm control in C++ applications (for instance using MFC). Though I've never done it.
AFAIK the .NET framework provides (so Visual Basic.NET, C#, ...) a SerialPort component that can make communication stuff as easy as MsComm do for VB6 (I never made an attempt). There is also a Microsoft example [^].
hope that helps.

A DLL is self registering (ie. by calling its DLLRegisterServer known function, in your case regsvr32.exe call this function) when it is a COM server.

You can use native DLLs from .NET using P/Invoke. Following MSDN article may be of help -

Dear friends,
Can I use any alternate for DSO Framer control to display document, excel, ppt, pdf etc files. I tried aspose too, but it was
not meeting our requirements. Because they want a tool which takes the documents as it is like DSO Framer. In aspose to
change the document format we need to change the code also.
And I need to email this document too. So that document may be changed so frequently. And dont forget that document must have
to be made using .Net frame work library(com component is not preferable). What shoud I use in this case. Please help me.
Thank you.

Hi Sohail,
Thank you for ur valid information. Actually I have made an IE toolbar using
vc++ ATL COM. It cotains Threads, And many things that mfc supports.
For example,
It consists of a Ticker that shows some information from a server. The ticker
is
actually a class inherited from CStatic. And also Threads in VC++ , that
performs various functionalities like, Collecting data from Server. Showing
Advertisements live , from different sites etc. So I think, I cant perform
these things in Mozilla tool bar made from XML. Right na.
Thanks
George

well you can certainly do in Mozilla what you have so far created in IE.
From what you said, I beleive your UI logic and Business logic are clubbed together and created only for IE.
If you seperate out the UI logic of toolbar in your IE and put the business logic in a seperate COM dll which is callable from the UI logic then you can invoke the same business logic from within Mozilla toolbar. The UI logic of toolbar is written in XML but there is a way to call COM interface methods. Mozilla also has something called XPCom - COM variant.
I hope this helps
