Hi
I relatively new to C# and at the moment I am having troubles accessing
com objects within C#.
I am working in VS.net. I add the com library I want to access to my
references. Accessing classes exported in this com interfaces will throw
a System.Security .SecurityExcept ion.
(System.Securit y.Permissions.S ecurityPermissi on)
Status of failed permission:
<IPermission class="System.S ecurity.Permiss ions.SecurityPe rmission,
mscorlib, Version=1.0.500 0.0, Culture=neutral ,
PublicKeyToken= b77a5c561934e08 9"
version="1"
Flags="Unmanage dCode"/>
I also tried inserting the following code before trying to call
unmanaged code, but with no success.
SecurityPermiss ion perm = new
SecurityPermiss ion(SecurityPer missionFlag.Unm anagedCode);
perm.Assert();
Any Ideas?
Regards

Stephan,
Where are you running this application from? Is it an ASP.NET
application, or are you running it from the web, or a network share?
In any of these situations, you are not given permissions to run
unmanaged code. This is why your calls are failing, most likely.
If this is the case, to fix this, you have to go to the .NET framework
administration tool (it's under administrative tools) and change the
permission sets for the app (based on it's hash, a strong name, or other
identifier) so that you have unmanaged code permission.
Hope this helps.

I am currently trying to port some VB6 code to VB.NET because of a possible

All my variables are currently encapsulated in public UDTs. If I could

important engine of the system without having to...

Hello,
I have a class inside another class. The Scenario is like Car->Engine, where
Car is a class with a set of properties and methods and Engine is another
class inside it with its own set of properties.
I want to know if there is a way to access the methods and the properties of
the Owner class for the class that's inside it? I.e. I want to find out
within Engine what make the Car is which is exposed by the property
Car.Model.

Hi,
I have a blood glucose meter (a Lifescan OneTouch Ultra in case anyone

to use the software provided by Lifescan. The software is free and is
okay but it's not very good at manipulating the data.
Although I connect my meter using a USB cable, it can be connected by a

I'm accessing MSOutlook via Microsoft.Office.Interop.Outlook. It works
fine if I add a reference to either version 11 (Outlook 2003) or
version 12 (Outlook 2007) of the interop assembly to my project.
However, I don't want to build two different applications for each
version; I want my application to detect and use the current version
at runtime. But when I load the assembly at runtime, I don't have

Say I have a base class B and four derived classes d1, d2, d3, d4. I
have three functions fx, fy, fz such that:
fx should only be called by d1, d2
fy should only be called by d2, d3
fz should only be called by d1, d3, d4
I think I have two options.
(1) Make all functions virtual and define them in the required derived
classes. This will of course lead to a lot of code duplication and
problems in maintainability.

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.

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,...
