bytearray

问题 Given a bytearray and a new bytearray of which i need to overwrite its content on the original bytearray but starting from a specific position/offset (A) as shown in the image below(we can say B is the length of the new Array). Also handling the new length if the overwriting exceeds the actual length of the original array. (this is needed for .WAV file overwriting in different positions). here is what i have tried so far but no luck. public byte[] ByteArrayAppender(byte[] firstData, byte[]

问题 I need to get specific bytes from a byte array. I know the content of the first byte I want and I need x bytes after that. For example, I have byte [] readbuffer { 0, 1, 2, 0x55, 3, 4, 5, 6}; byte [] results = new byte[30]; and I need the 3 bytes that appear after "0x55" byte results == {ox55aa, 3, 4, 5} I'm using: Array.copy(readbuffer, "need the index of 0x55" ,results, 0, 3); I need to find the index of 0x55 PS: 0x55 is in an aleatory position in the array. PS2: I forgot to mention before

问题 The complied SWF is not showing the preloader until the whole SWF completely loaded. Any hepl would be really appreciated, I googled the whole night couldnt find anything on this, at least for me. 回答1: You can not embed the ByteArray into your main document class, because classes that are referenced from the document class will automatically be included on frame 1. The best way to preload assets is to have a separate Preloader class and Main class. You want your Preloader class to export on

问题 I am a .NET Developer, but the question I am having is not related to .NET Please keep this in mind even if my question sounds very trivial. This is my question: We have an swf in the browser, which communicates with a java extension Its done using Smartfox Server(Used for MMO apllications) From the swf we are grabbing a portion of the screen as "Byte Array" in action script(3). And in Java, we are calling a function that converts the ByteArray to Image and then saves it. Our Java developer

问题 I have a bytearray to which I have to add a number as a four character string. i.g. 14 should be added as '0014'. I tried this: id = 14 arr.append(bytearray(format(id, '04x'))) but it results in: TypeError: unicode argument without an encoding 回答1: Really you should explicitly specify the encoding when converting to bytes from a string. This answer also works in python 3: arr.extend(format(id, "04x").encode('ascii')) 回答2: arr.extend(bytes(format(id,"04x"))) 来源： https://stackoverflow.com

问题 I have a byte array, that I need to write to txt-file. After that I need to read that byte array from there and here appears a problem. I read this Convert Java string to byte array But it works only with positive numbers. Here what I have public static void main(String args[]) throws UnsupportedEncodingException { byte [] a= new byte [2]; a[0]=15; a[1]=-2; String line = new String(a, "UTF-8"); byte[] b = line.getBytes(); System.out.println(b[0]); System.out.println(b[1]); } and result is 15

问题 I want to put multiple images in JSON object using byte stream format, i wrote the following code.

问题 hi i have this kind of array int[] arrayint = new int[32]; and it contains arrayint[0] = 99 arrayint[1] = 121 arrayint[2] = 99 arrayint[3] = 66 ... is there a simple way to copy that integer array into a byte array like i want to make this byte array byte[] streambit; and it should be the same to the arrayint value i want to be like this the output streambit[0] = 99 streambit[1] = 121 streambit[2] = 99 streambit[3] = 66 ... 回答1: streambit = arrayint.Select(i => (byte)i).ToArray(); Just make
