bytearray

问题 I am receiving a service response which is byte[100] how can i convert it to a guid ? byte[] response = wc.UploadValues(url, "POST", nvc); string Guid = new Guid(response).ToString(); Response.Write(Guid); 回答1: There is a Guid constructor which allows you to initialize a Guid from a 16-element byte array. So you will have to first extract the 16 elements from your 100 elements array into a new one and then initialize the Guid. Which 16 elements to extract from your 100 elements array would of

问题 I'm trying to send a string of hex values through udp, 11 22 33 44 37 4D 58 33 38 4C 30 39 47 35 35 34 31 35 31 04 D7 52 FF 0F 03 43 2D AA using UdpClient in C++. What's the best way to convert string^ to array< Byte >^ ? 回答1: This works for me, although I haven't tested the error-detection all that well. ref class Blob { static short* lut; static Blob() { lut = new short['f'](); for( char c = 0; c < 10; c++ ) lut['0'+c] = 1+c; for( char c = 0; c < 6; c++ ) lut['a'+c] = lut['A'+c] = 11+c; }

问题 I'm having problems sending a ByteArray over to my Zend_Amf_server. I get a NetConnection.Bad.Call back from the server. If I send a variable with another datatype then ByteArray it works fine. I used the same script before with AMFPHP witouth any problems. But for this project I really need this to work in Zend_Amf. AS3: var path:String = "/images/picture.jpg"; var ba:ByteArray = jpgencoder.encode(bitmap.bitmapData); var nc:NetConnection = new NetConnection(); nc.connect(zend_amf_server); nc

问题 I need to be able to load a jpeg/png image from disk and show it in flex and send it to a server as a base64 encoded string. But once the image file is loaded, in my flash.display.LoaderInfo object, the bytes property (type of ByteArray ) contains more byte than the file content. Example: image file size: 3089 flash.display.LoaderInfo.bytesTotal:3089 flash.display.LoaderInfo.bytes.length:3155 As i need to encode the flash.display.LoaderInfo.bytes in base64 string, i don't know which part of

问题 I'm able to record sound with a Flash application embedded in my website, this audio is saved to a ByteArray, which I need to pass to Javascript in order to post to my server along with other required data. I know I can use AS3 ExternalInterface class to communicate with Flash from Javascript, but what would be the appropriate format or variable type in javascript to hold the ByteArray, and how can I ensure that I won't lose much audio data when doing so? 回答1: Maybe it's not possible for you

问题 So I have binary FRX files, from which I need to extract strings into Java. I wrote this into my Java program like so: FileInputStream ReadFRX = null ; FileOutputStream TempCapt = null ; try{ // refNum is hex number on end of VB form property converted to decimal, ex: $"frmResidency.frx":0134 int refNum = Integer.parseInt(line.substring(line.length() - 4, line.length()), 16); // FRXtemp.txt is created, to temporarily write FRX captions onto to be read from. PrintWriter writer = new

问题 In my project I need to AND two binary array of size 40 bytes(320 bits) and then compute set bit count in C++. I found some algorithms to do this but I want to know what is the fastest way of implementing it in c++. I mean what c++ data type would be proper?(unsinged char*,unsigned int 32,u_int64,...). I know many algorithms are compatible with 32bit integer although my array size is 40 bytes . what about the algorithms described in this link: Fast Bit Counting Techniques which one is faster?

问题 I am using the following code in iOS to convert an mp3 file to byte array. However, on entering the while loop, it gives err = -40 (OSError = -40) . Can anyone please help. Or kindly let me know how i can convert an mp3/wav file to bytearray. Reference - How to convert WAV/CAF file's sample data to byte array? NSString *urlHere = [[NSBundle mainBundle] pathForResource:@"r2d2" ofType:@"mp3"]; CFURLRef url = (CFURLRef)[NSURL fileURLWithPath:urlHere]; AudioFileID audioFile; OSStatus err =

问题 I want to playback audio file from byte code. I already have byte code for audio file. But when I playback with System.Media.SoundPlayer, I got error as "{Sound API only supports playing PCM wave files."}. My audio file format is (CCITT A-Law). Can any one who have this knowledge share with me pls?? Thanks. 回答1: The standard G.711 tells you how to convert 8 bit A-law into 16 PCM. Here's a code snippet 回答2: WAV files can be encoded in many ways, usually PCM or MP3. .NET only supports PCM. Use

问题 I'm making a wordcount program and i want to write the total number of words at the end of the file. As i'm using FileOutputStream i've to convert my string to Byte array. But i'm getting a compile time error. Please help me out with this. Byte[] msg; msg="Total Number of words are: ".getBytes(); and i'm getting compile time error like this: error: incompatible types: byte[] cannot be converted to Byte[] and also i'm using write method and passing a byte arraylike this: fout.write(msg); where
