Hi
We are rewriting a COM object in C#. The COM object
returns HRESULT for invalid arguments, null values etc.
The HRESULT is created using the MAKE_HRESULT macro in C++.
1.What is the C# equivalent of MAKE_HRESULT?
2.How do I return a HRESULT or an exception from my C#
program that would indicate a FAILURE.
Any help is appreciated.
Thanks.

Hi,
we have a (unmanaged) ATL COM server, which implements two interface:
ITestInterface1 and ITestInterface2. Both of these interfaces also support
the ISupportErrorInfo-interface.
Interface implementation is divided into two class: CTestInterface2, which
implements the ITestInterfac2, and CTestInterface1, which implements
ITestInterface1 AND ITestInterface2.

Exception class has HRESULT as protected member. Is there a header file or tool to get the entire mapping of C# Exception to HRESULT? Any tools / header file / links appreciated

Is this
Exception from HRESULT: 0x800401A8
an error or a bug? I've been trying to build a chart in Excel through VB.net
(which isn't documented) so I'm running completely blind. What examples I
have found are from VB6 which doesn't convert well. When I do try a new
piece of code like:
oChart.Legend.Position = Excel.XlLegendPosition.xlLegendPositionBottom

Hi,
If I call my own DLL from Javascript, a HRESULT is returned.
Javascript cannot cast this to an integer.
Is there any other way of typecasting this returnvalue to integer, wihout
using the exception method which is described everywhere ?
Please note that I am unfamiliar with javascript, I am used to C/C++.
My Javascript call looks like :
var result;

Hi,
I'm accessing COM objects from C#.net.
In case of error a COMException is thrown which includes the HRESULT.
But how do I get the description for the HRESULT?
The Message property of the COMException does not contain any useful
information.
Example (I've got a german OS only, so I don't know the exact english
version of these texts):
HRESULT is: 800706ba

I've been Googling and there is many many hits but I can't find what I want.
I've read at one time how DotNET treats HRESULT but can't find it now.
Does it return HRESULT unchanged or does it check it for error-return or
what?
Thanks for any help

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.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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. For most users, this new feature is actually very convenient. If you want to control the update process,...
