How do I make a self extracting archive using C#

14 Jul 2018 by OriginalGriff

Don't read it as text: read it directly as bytes: byte[] data = File.ReadAllBytes(pathToFile); File.WriteAllBytes(pathToExe, data); Data in ASCII can be just 7 bit, and different systems will interpret some of it in different ways (like \n and \r being "condensed" when you read them for...

Quote: Is the size of int is same for all languages or it varies with the language you use? Size of int have evolved with time. In the 80"s int was 8 bits because' processors were 8 bits. then it was 16 bits and now it is usually 32 bits. lets guess in future it will be 64 bits. if you get a C...

How do I convert a string into array of byte?

Hello, I want to convert a data type in a byte address. + And i have to escape that "0x" from my data. And the data type will be as string(i think) but it may be int or whatever. I don't know what to write in code. Thanks! For example: What I have tried: public void blabla(string...

How do I convert a string into array of byte?

27 Sep 2018 by OriginalGriff

That's possibly more complicated that you think: a string is an array of characters (or it can be thought of, and treated as such) but a char in .NET is not equivalent to a byte, it is a Unicode value and is thus a 16 bit value, unlike byte which is an 8 bit value. There are ways to convert it,...

Encoding string to bytes is adding unnecessary "00"s

19 Nov 2018 by Member 11117644

Good day, I have a 16 byte string which I encode to bytes and then immediately convert it to a readable Hex string. The result is that it added 00 after every single Hex and I cannot seem to understand why. My String: var message1 = "Thats my Kung Fu"; Conversion: var stringToByte =...

var stringToByte = Encoding.UTF8.GetBytes(message1); orvar stringToByte = Encoding.ASCII.GetBytes(message1); would both give you the result you are expecting.

You used the Unicode encoding to get the bytes. It's not behaving lie you expect probably because you have no idea what Unicode is. I suggest reading up it here: What is Unicode?[^].

How java bytestream works?

17 Jan 2020 by 49R

How raw data is divided into bytes. As present audio contains 32bit(2^32 tones) it ranges from 2^0 - 2^32. ex -> 6710497.. (Considering decimal) how is it divided to 67 104 97 Does FileInputStream has a method to check like if(671>256){send 67 , next append 1} What I have tried: ...

How java bytestream works?

17 Jan 2020 by Richard MacCutchan

Any file, or data, is just a stream of bits. In general it is convenient to handle the stream as a collection 8-bit bytes. However the bytes are often grouped together to make different types of information (int, double, string etc.). The key is that you need to know the structure of the data in...

17 Jan 2020 by Patrice T

Quote: How java bytestream works? In a stream, a byte is the smallest chunk of data you can handle because it is how computer works. You can consider that a byte is like a digit (for computer), just like for us, a digit is 0-9 for us. A bytestream have no idea of the meaning of bytes or their...
