_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?Why is System.Text.Rune named like this?
.NET uses UTF-16 for string encoding. This means: char type, which is atomic unit of string, is 16-bit size data type. that surrogate pairs are used for Supplementary code points, U+10000..U+10FFFF, while for Basic Multilingual Plane, U+0000..U+FFFF one char is sufficient to express any Unicode scalar value. .NET Rune comes in with ability to bypass surrogate pair problems, e.g. their unintended split. Thus by one variable all scalar values can be expressed. var a = new Rune('a'); var grinnigFace = new Rune ( '\uD83D', '\uDE00' ); There exist many terms related to string and char types: symbol, character, pictogram, emoji, grapheme, script, letter, mark, punctuation, accent, diacritics, emoticon, … .NET chose to use textual element as synonym for what is grapheme +/ cluster in Unicode. Unicode® Technical Standard #51 Note that all emoji sequences are single grapheme clusters: It is also not 100 % correct to use "grapheme". Grapheme In linguistics, a grapheme is the smallest functional unit of a writing system. While let say this 🧑🏿:christmas_tree: emoji is composed as sequence of: 1F9D1, 🧑, \Ud83e\Uddd1 1F3FF, 🏿, \Ud83c\Udfff 200D, , \U200d 1F384, :christmas_tree:, \Ud83c\Udf84 hardly can be any unit considered functional unit of writing system. Document The Unicode® Standard: A Technical Introduction is more specific. For example, in historic Spanish language sorting, "ll"; counts as a single text element. However, when Spanish words are typed, "ll" is two separate text elements: "l" and "l". Text elements are encoded as sequences of one or more characters. Certain of these sequences are called combining character sequences, made up of a base letter and one or more combining marks, which are rendered around the base letter (above it, below it, etc.). For example, a sequence of "a" followed by a combining circumflex "^" would be rendered as "â". There can be seen some intersection between Unicode and .NET on text/textual element. Nonetheless, rather opaque terminology reign is apparent. The Rune https://www.vocabulary.com/dictionary/rune A rune is a letter used in early Germanic writing. A linguist might be interested in runes because they're evidence of ancient languages, while a mystic might use runes, believed by some to have magical properties, in fortune-telling. https://www.thefreedictionary.com/rune 1a) Any of the characters in several alphabets used by ancient Germanic peoples from the 3rd to the 13th century. 1b) A similar character in another alphabet, sometimes believed to have magic powers. 2) A poem or incantation of mysterious significance, especially a magic charm. After deeper look, "rune" does not resemble any of terminology used by Unicode and seems to be tightly coupled with Germanic tribes' writing system. As far as I can see, Rune is nothing more then Unicode Scalar Value. It is not important whether UCP is expressed by 1:1 numeric relation, surrogate pairs or by series of doggies and cats. It could be said that .NET is about to contribute to terminology goulash: Why Rune is not UnicodeScalarValue or something more technical accurate? I failed on finding any reference on why this name was chosen. Is there some specific reason? Or Rune is just fine as grapheme, glyph, symbol and others would be?
Possible to change method called inside foreach?
I have a created a function as below public static ICustomers[]? SanitiseCustomers(this string[]? custVals, float boxed = 0.5f) { List<ICustomers> customers = []; foreach (var c in custVals) { customers.Add(c.Sanitize(boxed)); } return [.. customers]; } I want to replace the Sanitize function within the foreach loop to a different method. 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?Simple Guide On Effective Use Of Parallel Programming For C# In A Managed Code Environment:
Parallel programming in C# uses a variation of Managed Threading, that relies on PLINQ, Expression Trees, The Barrier Class, Thread Class, BackgroundWorker Class, SpinWait Struct, SpinLock Struct, and Thread-Tracking Mode for SpinLock. The reason is that it's faster to use the environment to determine how many cores / threads are available, as to not starve the device of resources, which at that point, you have to use the BackgroundWorker Class to manage each task you've created. Often in this scenario, you can end up with a deadlock condition, because you have more than one task trying to access a shared resource. It's much easier and faster to split up each task, ONLY using byte arrays, assigning each task individual byte arrays to sort / parse, encrypted or not, with the Stream class, or a sub variation of that Class, and then when each task finishes, they all finish at different times, but the shared resource is divided up into portions, so that they will only be able to fill one area of that array. The reason why Barrier is used in this situation, is it forces each one to wait until all the tasks are finished, or until they all ARRIVE at the same place, which solves one timing issue, yet it might create another where there's a bit of a timing mismatch if your estimates are wrong, you overshoot or undershoot I mean. At the very end, you can use a separate process to just COPY from each individual array, without a deadlock scenario occurring. The only issue, is you have to estimate how many threads are available ahead of time, and you can't use every single thread, yet you're going to have to divide a single resource between all those threads. Beforehand, you have to verify if it's a waste of time to use more than one thread. The reason why I say this, is that a lot of people use reference types, not knowing they are immutable, and they take a huge / massive performance hit because of this. Often you have to convert strings into byte arrays, or use a pre-initialized character array at the start of the program, which contains the Unicode values that you want to recast individually as strings, and then use a byte array as an INDEX or a placeholder, of a Unicode character array. If you’re not encrypting the byte arrays, or using them for text parsing, which byte arrays tend to be best in high throughput scenarios, than integer arrays will suffice. The index can be scrambled based on how you want to represent that one string, though it's smarter to only cast a new reference type when you want to display text on the screen. If you spend too much time manually parsing using built-in libraries, it's REALLY SLOW. A byte array is better to use than an integer array in this sort of situation. You might have to create separate indexes with a byte array representing a set of binary flags, to determine whether each one is a letter, number, symbol, etc, or how you want to classify each one based on the code chart that you're using. You would be better off in that situation to just use right shift / left shift / XOR, etc, to set the flags. Then you have something which is also very fast, and almost equivalent to a Barrel Shifter, given C# does not allow you to use pointers, as it's managed code / a managed environment. All the Boolean Logical Operators with Compound Assignment rely on pre-initialized Cast Expressions of Integer Literals, Bitwise and Shift Operators, combined with Lambda Expressions, and Operator Overloading. The purpose of the Shift Operators is to mask / pad the bits of one byte value with zeroes, so that your Cast Expression Of An Integer Literal, which serves at the mask, always gives you a fixed / deterministic result, when used in conjunction with Boolean Logical Operators, especially if the value is smaller than 8-bits / a single byte, or you're dealing with a larger array has to represent a flag "register" with a size of ( 2 ^ 8 ) 256 bits, which is basically a Double-Word: "Microsoft Learn -

The Importance of Finding the Right Bra Size
Finding the right goldies bra size is one of the most important things you can do when shopping for a new bra. If your bra does not fit you correctly, you’re not only going to be uncomfortable, but you’re also going to end up with unsightly lines, straps digging into your skin, and a bra that isn’t lifting you to your fullest potential. goldies bras reviews While this may not seem like a big deal when you’re just wearing the bra by itself, it becomes much more noticeable when you’re wearing a shirt or other top. If you’re trying to find your perfect bra size, be sure to take all of your measurements. This includes the circumference of your bust, the length of your torso, and your bra size. Keep in mind that bra sizes are not just measurements of the cups. There are other parts of the bra that need to be measured and checked to ensure the correct size.
