Embedded .net Windows Forms Control Security Issue

Hi,
I have been trying to use a .net Forms control in my webpage to open up
an application(not epad) on the client. The control works fine when
embedded in a windows form, but I keep getting a security exception
when trying to run it from my webpage on my intranet. I have tried
playing with the Code Access Security settings, but I can't get it to
work.
What do you think?

Thanks,
Gal

Hi, I am trying to find the minimum security settings to allow a windows control embedded in IE have full trust. If I give the entire Intranet zone full trust, this works. However, this is very broad and gives the entire zone high privleges. I tried giving just the assembly full trust (using the full URL for the DLL), but this doesn't seem to work.

Hi folks, I'm embedding a Windows Forms User Control into an aspx web page. I've created the class library in C# and added the user control to it.

Hi, I managed to create a Windows Form Control and put it on my ASP .NET page. I have done the suggestion that is provided by modifying the security settings. From the stack trace, I would assume that the code throws exception when it is trying to retrieve the processes list that has certain name. Below is the code that I use to retrieve the processes. Process processes = Process.GetProcessesByName("xxxx");

Overview: 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,...
