bytearray

问题 How can I load external swf into bytearray with adobe flash AS3.. Here is my code.. var my_url1:URLRequest = new URLRequest("SWF/Lesson1.swf"); my_url1.method = URLRequestMethod.GET; my_url1.contentType = "application/x-shockwave-flash"; var urlloader:URLLoader = new URLLoader(my_url1); var myByteArray:ByteArray = new ByteArray(); urlloader.data = myByteArray; It not works well. But it isn't give any error. How can I fix this problem? 回答1: You should listen for COMPLETE event and set the data

问题 I think that this is a newbie type question but I have quite understood this. I can find many posts on how to convert a string to a byte array in various languages. What I do not understand is what is happening at a character by character basis. I understand that each character displayed on the screen is represented by a number such as it's ascii code. (Can we stick with ASCII at the moment so I get this conceptually :-)) Does this mean that when I want to represent a character or a string

问题 I have to Send Byte Array to my java application From Android device.I m using ksoap2 for that in android and i have created web service in java with axis2 to receive that byte array and create file at server for further processing. Let me Give you Full explanation.i am Recording a wave file in android device and then that wave file need to be send at java application which is on server.i had created one web service in java application with axis2 name as "get_wave_byte" which converts the

问题 I have an array of bytes defined as unsigned char ptr = new unsigned char[1024]; fillWithSomething(ptr, 1024); Then, I need to store the ptr variable in a Local< Array> variable of V8 Engine or another kind of V8 data type. Currently, I am converting the array of bytes into a string in order to store in a Local< String> variable, but this approach is inefficient to my application. Thanks in advance. UPDATED (thanks to Vyacheslav Egorov) I test the solution with an external array but I can't

问题 I am trying to send a .jpg file which is on my android device to my server computer. To do this, I am converting the picture into a byte array by a java android application, and sending it as an argument to my server computer. I`m doing this by a web service call. The first function is edited: public static byte[] ImageConvertion(){ File inputFile = new File("/storage/emulated/0/IFSpictures/icon-si_strapclamp.jpg"); byte[] data; try{ FileInputStream input = new FileInputStream(inputFile);

问题 I am using JNA. and i am getting byte array of raw data from my c++ method. Now i am stuck how to get buffered image in java using this raw data byte array. I had tried few things to get it as tiff image but i dint get success. this are the code i tried so far. here my byte array contains data for 16 bit gray scale image. i get this data from x-sensor device. and now i need to get image from this byte array. FIRST TRY byte[] byteArray = myVar1.getByteArray(0, 3318000);//array of raw data

问题 I have the following Java code working as expected, to convert some numbers to an array of Bytes before writing to a stream. byte[] var1 = new byte[]{ (byte)-95, (byte)(240 / 256 / 256 % 256), (byte)(240 / 256 % 256), (byte)(240 % 256), (byte)0 }; I need to write the same in VB .net I tried the following code in VB .net, but no success. Dim var1(4) As Byte var1(0) = Byte.Parse(-95) var1(1) = Byte.Parse(240 / 256 / 256 Mod 256) var1(2) = Byte.Parse(240 / 256 Mod 256) var1(3) = Byte.Parse(240

问题 I am confused on how to convert short array to byte array. E.g. I have the follwoing short array short[] shrt_array = new short[]{ 0x4 , 0xd7 , 0x86, 0x8c, 0xb2, 0x14, 0xc, 0x8b, 0x2d, 0x39, 0x2d, 0x2d, 0x27, 0xcb, 0x2e, 0x79, 0x46, 0x36, 0x9d , 0x62, 0x2c }; By using this link Converting short array to byte array the two methods of conversion, I get the following two different byte arrays: expectedByteArray = new byte[] { (byte) 0x4, (byte) 0xd7, (byte) 0x86, (byte) 0x8c, (byte) 0xb2, (byte)

问题 I'm storing an IPV4 address on a SQLSERVER 2008 database as Binary(4). So, I'm converting the values before data input (and due to company restrictions I CANNOT create functions inside the db, well thats not up for discussion). public static byte[] IpToBin(string ip) { return IPAddress.Parse(ip).GetAddressBytes(); } public static string HexToIp(string ip) { return new IPAddress(long.Parse(ip, NumberStyles.HexNumber)).ToString(); } After IpToBin is called, the data generated is (for example

问题 Is it somehow possible to convert an byte array to image data without using canvas? I use currently something like this, however I think that can be done without canvas, or am I wrong? var canvas = document.getElementsByTagName("canvas")[0]; var ctx = canvas.getContext("2d"); var byteArray = [ 255, 0, 0, 255, 255, 0, 0, 255, 255, 0, 0, 255, // red 0, 255, 0, 255, 0, 255, 0, 255, 0, 255, 0, 255, // green 0, 0, 255, 255, 0, 0, 255, 255, 0, 0, 255, 255 // blue ]; var imageData = ctx.getImageData
