Hello everyone,
I am implementing a simple C# OLE DB Provider (C# COM Server). For C#
(managed code), I am wondering what is the entry point (which coclass and
which method), client will invoke at first?
It is clear if I write my own client, but I am confused about other clients
which I do not have source codes, for example, if I use Microsoft Excel (as a
client) to invoke my C# OLE DB Provider, which is the entry point? Any
reference materials or debug tools?
thanks in advance,
George

George,
Well, if the providers are publically accessible classes, the answer is
any of the methods/properties on your interface or classes can be entry
points. There is no restriction on when what will be called. Whether or
not it is valid is another issue, but theoretically, any of them could be
called.

Thanks Nicholas!
Do you know any way to debug? For example, I want to know which
coclass/interface the client is going to access (and possibly I forget to
implement) for C# managed code?
For C++ COM, I always debug through DllGetClassObje ct, but in C#, since it
is managed code, there is no single entry point -- entry point is delegated
to mscoree.dll, so I do not know a way to debug. Any good ideas?
regards,
George

Hi Everyone,
I am new to Server control development and I am wondering how do I define
the entry point for a server control? In a regular page you define Page_Load
as an entry point and in a windows application using C# you define the entry
point as void Main(){}. But in a Server control I think it is seperate then
writing the entry point as static void Main(){}

Hello everyone,
I have built MSDN OLE DB Sample Provider and successfully built/debug it
using Microsoft Excel as client. I have found that in DllGetClassObject
(classfac.cpp), the class SampProv is initialized as the 1st coclass, then
DataSource object will be created in QueryInterface.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
