_EnumDesktopWindows API problem
_EnumDesktopWindows API which uses User32.dll stopped working when the patch having OS build number 26100.3775 was updated on Windows 11. The version which was thus installed for Windows 11 is 24H2. It happen also on windows 2019 server having 24H2 as version number. When it tries to get a windows handle of a FORM, it freezes and doesn't allow the user to do anything. What seems to be the problem & how this can be rectified? Anyone's help will be deeply appreciated. Thanks...
Specify locale/language for exception messages to user during runtime.
I am using VB 2022 with .NET 8 & 9. I develop applications that allow the user to specify which language they want the GUI elements to be displayed in while the application is running - regardless of what language the users' MS Windows profile is set to. The reason I do this is because some companies (mine included) require all systems to be set to the U.S. English (EN-US) regional/locale settings. This is very easy for me to achieve, even for expected user errors which I can head off. However, unexpected system error messages are always displayed in the English language because the system is set to the English language. Is there any known way to force unexpected error/exception messages to be displayed in a language other than the system's current language? If I knew every single possible error that could be thrown up, as well as its corresponding error code/number, I could create translations myself. But, unfortunately, I have no way of listing every possible system error that could be thrown up during runtime. It would be nice if Microsoft had a COMPLETE list of these somewhere. But every list I've seen is fragmented and incomplete, and sometimes doesn't include a corresponding error code with the message. Try 'Attempt the following block of code. '/////////////////////////////////////////////// ' E X E C U T E S O M E C O D E H E R E ! '\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ Catch e As System.Exception 'Trap any unexpected system error. MessageBox.Show(e.HResult.ToString & NewLine & e.Message, MyCaption, MessageBoxButtons.OK, MessageBoxIcon.Error) 'Display the error message to the user. End Try Even though the user's system is set to the English language, I want to be able to display the message passed in the 'e.Message' member from the codes sample in whatever language the user has specified their GUI to display in during that application's runtime. Any ideas how to achieve this? BTW... the ability to do this would be an AWESOME feature for Microsoft to add to future .NET releases.
C# JSON deserialization returns null
Hi there, so first of, I just started working with JSON deserialization today and just know the bare basics. Basically I am currently developing a bot wich should get data from an API of a minecraft server. So far everything works perfectly except one thing: Since a minecraft uuid can start with a number (like for example "121e2d73913041ffaa49af39d124673f") visual studio automatically creates the uuid part with "_" ("public _121E2d73913041ffaa49af39d124673f _121e2d73913041ffaa49af39d124673f { get; set; }"). Now, when I try to request data from a uuid wich starts with a letter everything works fine. However when I request it from a uuid with a number, it will return null. My guess is, that since the JSON itself does not have "_", it wont get deserialized into the in-code version with "_". -> btw, I am using System.Text.Json, not Newtonsoft.Json but would have no problems changing... I hope. So, my question is, if there is a way to get this to work or maby work arround it? Thanks in advance :D

Enhancing Console.ReadLine to Accept a Message Parameter
n Python, the input function allows you to display a message and wait for user input in a single line of code. However, in C#, achieving the same functionality requires two lines: one for Console.WriteLine to display the message and another for Console.ReadLine to capture the input. Is it possible to have a ReadLine function in C# that takes a message as a parameter and waits for user input?
Possible to change method called inside foreach?
I have a created a function as below public static ICustomers[]?

I dont want to copy and paste the function and create a new one and changing Sanitize to FriendlyBox but trying to see if there is a way to switch the method name depending on the way this function is called?
