我正在尝试使用gogo添加一些控制台命令,例如创建命令,添加和显示
public void add(CommandSession commandSession, int i) {
List<Integer> il = commandSession.get("list");
if (il == null) {
il = new ArrayList<Integer>();
il.add(i);
commandSession.put("list",il)
} else {
我有一个带有ListView的活动,它将被包含国家名称的旋转器过滤。在选择某些国家的名称时,ListView会被过滤,但是在某些名称上它根本不显示任何内容。
代码:
public class Destination extends Activity {
ArrayAdapter<String> aa1,aa2;
/*listview*/ final String[] dest = {"Cordova, Alaska","Valdez, Alaska","Durres, Albania","Vlore, Albania
我的Ubuntu11.04服务器在互联网上有一些奇怪的行为,从几天以来。它在一些Java应用程序中运行得非常好。然后,突然它不再接受连接了。当我尝试ssh或http-连接我的服务器时,我不会得到响应,直到我得到超时。但平工作得很好。nmap还起作用:
Starting Nmap 5.21 ( http://nmap.org ) at 2011-08-29 10:52 CEST

RowNum = ROW_NUMBER() OVER (ORDER BY people_id)
当我在一段代码上运行valgrind时,它告诉我我的错误存在于这行代码中,但我似乎找不到它(如果类型为int,则为vector_size): float *rotations = (float *) calloc(vector_size*vector_size, sizeof(float)); 下面是valgrind的输出: Invalid write of size 4
==5488== at 0x109272: main (rotate_vector.c:20)
==5488== Address 0x4a47164 is 0 bytes after a block
我在c++中查看聊天应用程序时发现了以下内容
在服务器上
int ServerThread(int ID)
{
Buffer sbuffer;
char* Recv = new char[256];
ZeroMemory(Recv, 256);
// In Send we will copy the content of the struct
// and after this we will send "Send" to the client
char* Send = new char[sizeof(Buffer)];
