我试图为Twitter Bootstrap按钮创建微调器.旋转器应指示正在进行的一些工作(即ajax请求).

这是一个小例子:http: //jsfiddle.net/AndrewDryga/zcX4h/1/

HTML(完整的jsfiddle):

Unknown element (no animation here!):
<p>
  <button class="btn-success has-spinner">
    <span class="spinner"><i class="icon-spin icon-refresh"></i></span>
    Foo
  </button>
</p>

Works when width is defined:
<p>
  <a class="btn btn-success has-spinner">
    <span class="spinner"><i class="icon-spin icon-refresh"></i></span>
    Foo
  </a>
</p>

CSS:

.spinner {
  display: inline-block;
  opacity: 0;
  width: 0;

  -webkit-transition: opacity 0.25s, width 0.25s;
  -moz-transition: opacity 0.25s, width 0.25s;
  -o-transition: opacity 0.25s, width 0.25s;
  transition: opacity 0.25s, width 0.25s;
}

/* ... */

.has-spinner.active .spinner {
  opacity: 1;
  width: auto; …

我正在尝试发送HTTP请求并通过C#套接字从服务器接收响应,我是这种语言的新手.

我写了以下代码(IP解析正确):

IPEndPoint RHost = new IPEndPoint(IP, Port);
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Connect(RHost);

String HTTPRequestHeaders_String = "GET ?q=fdgdfg HTTP/1.0
Host: google.com
Keep-Alive: 300
Connection: Keep-Alive
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.205 Safari/534.16
Referer: http://google.com/";

MessageBox.Show(HTTPRequestHeaders_String, "Request");

byte[] HTTPRequestHeaders = System.Text.Encoding.ASCII.GetBytes(HTTPRequestHeaders_String);
socket.Send(HTTPRequestHeaders, SocketFlags.None);

String Response = "";
byte[] buffer = new byte[(int) socket.ReceiveBufferSize];

int bytes;
do
{
    // On this lane program stops to react
    bytes = socket.Receive(buffer);
    // This line …

几个小时我试图通过MPI发送2D数组到不同的线程.代码看起来像这样(我会留下评论来展示我已经尝试过的技巧):

类型定义:

// Define datatype
//MPI_Type_contiguous(N, MPI_INT, &mpi_vector);
//MPI_Type_vector(N, N, N, mpi_vector, &mpi_matrix);
//MPI_Type_vector(N, N, N, MPI_INT, &mpi_matrix);
//MPI_Type_contiguous(N, MPI_INTEGER, &mpi_vector);
//MPI_Type_contiguous(N, mpi_vector, &mpi_matrix);
MPI_Type_vector(N, N, 0, MPI_INTEGER, &mpi_matrix);
//MPI_Type_commit(&mpi_vector);
MPI_Type_commit(&mpi_matrix);

发送和接收:

int** tmp = new int*[N];
switch(r) {
case T1:
    inputMatrix(tmp, 2);
    MPI_Send(tmp, 1, mpi_matrix, T2, 0, MPI_COMM_WORLD);
    //task_T1();
    break;
case T2:
    //task_T2();
    inputMatrix(tmp, -1);
    MPI_Recv(tmp, 1, mpi_matrix, T1, 0, MPI_COMM_WORLD, &s);
    for(int i = 0; i < N; i++)
    {
        for(int j = 0; j < N; j++) …
