不是邮件，是工具——账号管理。但是你这个问题应该与设置没有关系的

wsock接收16进制数据后如何正确的添加到文本框中显示

快手三段, 积分 761, 距离下一级还需 239 积分
最近弄一个调试辅助工具，服务器发送的应答是16进制格式，我需要在文本框中显示出16进制数据。我的写法是：&&源代码 [ AAuto ]//wsock读取处理函数
netrecvcommand = function(nSocket) begin
var reads,recvbuf = wsock.recv( nSocket,);
if ( reads=-1 ){
//io.print( &客户端接收错误&);
//io.print( wsock.err.lasterr() );
if(mainForm.radiobutton_Aiscii.checked == true)
mainForm.edit2.appendText(recvbuf);
// mainForm.edit2.appendText( string.fromUnicode(recvbuf));
//mainForm.edit2.appendText(tostring(recvbuf,16));
io.print(&收到的数据是：& ,recvbuf);
mainForm.edit2.appendText(string.format(&0x%X&,tostring(recvbuf,16)));
但是上面接收后始终只能显示一个字节，不能显示其全部，但是这个字节也不是服务器发送过来的那个字节，
服务器发送应答(HEX格式)：FE 00 00 00 12 03 0E FC
我的客户端接收后就不能显示出来，如果服务器发的是aiscii命令就可以正常显示，希望哪位指点一下，谢谢。

%X 格式化的是一个数值，你传入的是字符串，可想而知结果是错误的了。
tostring(recvbuf,16) 这个函数指定16进制时，他的作用类似%X把一个数值转换为16进制，可是你传进去的参数是一个字符串，可想而知也是错知的了。
如果你想转换为上面的格式，参考一下 inet.url.encode，做一个简单的转换，如下：&&源代码 [ AAuto ]hex = function(s){
return ( string.replace(s,&.&,
function(c){
return string.format(& %02X&, c[1] )
io.print( hex(&这是接收到的字符串&) )

不过现在遇到一个问题，服务器发送：FE 03 04 01 FC 01
而我用你的这个函数处理过后能显示出来了，
显示结果：

我就不明白后面怎么出来那么多个字节，这个是与我设置的接收缓冲区有关吗？请指点一下，谢谢。

这是按缓冲区来发送的，多出字节应当是正常的，看你服务端的代码怎么写的了

var reads,recvbuf = wsock.recv( nSocket,);
我感觉是这个地方的问题，因为我将缓冲区设置为1024，后面解析出来的00字节就没有那么多了
但是我不明白是不是将整个缓冲区都给转换了？
我使用其他软件测试了，服务器是没有问题的，服务器是使用人家成熟的，问题就出在我的客户端上面。

你思考一下 reads 是起什么作用的，于是你会找到答案的。

我在回去仔细研究一下那个例子客户端看看，谢谢
那个好像就是一个容错的吧，接收发生错误就会返回
不是很理解
主题帖子积分
reads&&就是读取到的长度

谢谢“不净”的一直指导。
问题得到解决
只需要取出数据长度就可以了
string.left(recvbuf,reads)
具体的代码如下：&&源代码 [ AAuto ]//wsock读取处理函数
netrecvcommand = function(nSocket) begin
//var reads,recvbuf = wsock.recv( nSocket,);
var reads,recvbuf = wsock.recv( nSocket,);
if ( reads=-1 ){
//io.print( &客户端接收错误&);
//io.print( wsock.err.lasterr() );
if(mainForm.radiobutton_Aiscii.checked == true)
mainForm.edit2.appendText(string.left(recvbuf,reads));//string.left(recvbuf,reads)这个是老大提醒的
io.print(&收到的数据是：& ,hex(string.left(recvbuf,reads)));
mainForm.edit2.appendText(hex(string.left(recvbuf,reads)));
//16进制处理函数
hex = function(s){
return ( string.replace(s,&.&,
function(s){
return string.format(&%02X &, s[1])
}希望后面的朋友不要走弯路。
问题到此结束。
