Call me crazy, but I'm the type of guy that likes constructors with parameters (if needed), as opposed to a constructor with no parameters followed by setting properties. My thought process: if the properties are required to actually construct the object, they should go in the constructor. I get two advantages: I know that when an object is constructed (without error/exception), my object
叫我疯了,但我是喜欢带参数的构造函数(如果需要)的人的类型,而不是没有参数的构造函数,然后是设置属性。 我的思想过程:如果需要属性来实际构造对象,则应该在构造函数中进行。 我有两个好处: 我知道当一个对象被构造时(没有错误/异常),我的对象是好的。 它有助于避免忘记设置某个属性。 就形式/用户控制的发展而言,这种思维方式已经开始伤害我。 想象一下这个UserControl : public partial class MyUserCon
I'm using winforms and the DomainUpDown control's height is locked at 20 pixels, which results in "y"'s and other characters with descenders cut off on the bottom. My initial thought about how to fix the problem was to change the controls height, but I couldn't do so. In the designer I only have controls to drag it's size by width. The property page immediately r
我使用的是WinForms,而DomainUpDown控件的高度锁定在20像素,这导致“y”和其他字符在底部被截断。 我最初想到如何解决这个问题是为了改变控制高度,但我不能这样做。 在设计师中,我只有控件将它的大小拖动。 该属性页面立即恢复对我制作的高度的任何更改。 试图改变代码中的值静静地失败; 没有错误,没有例外,但没有改变的价值。 在这个样本表格中,DomainUpDown中的“g”将被删除。 public partial class Form1 : Syst
If you create a panel on a form and set it to Dock=Top and drop another panel and set its Dock=Fill, it may fill the entire form, ignoring the first panel. Changing the tab order does nothing. Docking layout depends on the order of sibling controls. Controls are docked "button up", so the last control in the collection is docked first. A docked control only take the layout of previ
如果您在表单上创建面板并将其设置为Dock = Top并放置另一个面板并设置其Dock = Fill,则可能会填充整个表单,而忽略第一个面板。 更改标签顺序不做任何事情。 停靠布局取决于兄弟控制的顺序 。 控件停靠在“按钮”上,因此集合中的最后一个控件首先停靠。 停靠控件只考虑以前停靠的兄弟姐妹的布局。 因此,Dock = Fill的控件应该是兄弟顺序中的第一个(顶部),如果您希望它考虑其他停靠控件。 如果它不是第一个控件,则早
When I try to run a LINQ query of the form: MongoCollection<MyEntity> collection; collection.AsQueryable().Where(entity => (entity.Flags & MyFlags.AFlag) != MyFlags.None); I get an ArgumentException with the message Unsupported where clause: ((Int32)((Int32)entity.Flags & 4) != 0). Is this a known bug/feature? Is there any workaround? From the documentation it seems
当我尝试运行表单的LINQ查询时: MongoCollection<MyEntity> collection; collection.AsQueryable().Where(entity => (entity.Flags & MyFlags.AFlag) != MyFlags.None); 我得到一个ArgumentException Unsupported where clause: ((Int32)((Int32)entity.Flags & 4) != 0). 这是一个已知的bug /功能吗? 有什么解决方法吗? 从文档看来,MongoDB似乎具有按位更新,但不是按位查询。 为了进行比
I would like to confirm that any value in a ip header bigger than one byte (short, int.. Or their alternative int16_t..) should be converted to big endian using ntohs/ntohl etc to send over the wire. Did The kernel managed that under the hood when normal socket were used or another technic was used? It is quite of a mess since some functions, like getting the ip address of the interface with
我想确认一个大于一个字节(短,int ..或其替代int16_t ..)的IP头中的任何值应该使用ntohs / ntohl等转换为大端。 当正常的插座被使用或者使用了其他技术时,内核是否能够在引擎盖下进行管理? 这是相当混乱的,因为一些函数,如获取与ioctl的接口的IP地址似乎已经把数据放在sockaddr_in *的时候,以大端的方式。 它输出我的地址,如36.2.168.192(printf的%d),但ifreq的输出像192.168.2.36 码 int addr = ((struct s
I have to send multiple variables types over an udp socket: an int array and a char. I would like to send it on the same udp packet. What is the standard solution? Convert everything to bytes or something similar? I'm using: sendto(int sockfd, const void *buf, size_t len, int flags, const struct sockaddr *dest_addr, socklen_t addrlen); My code is something like: int buffer[100]; char
我必须通过udp套接字发送多个变量类型:一个int数组和一个char。 我想发送它在相同的udp数据包。 标准解决方案是什么? 将所有内容转换为字节或类似的内容 我使用:sendto(int sockfd,const void * buf,size_t len,int flags,const struct sockaddr * dest_addr,socklen_t addrlen); 我的代码是这样的: int buffer[100]; char flag = '0'; int i = 0; for (i = 0; i < 50; i++) { buffer[i] = i * 2; }
I'm new in c# =) I have a litle question about udp socket. I have a chat server that receives packets to a specific structure (udp datagram). Why program receives data when the socket buffer is full? Does all that come after should not be be lost? Maybe packet fragmentation occurs? Packet structure : udp_headers(28 byte)| dataIdentifier ( 4 byte)|name length(4 byte)|mesage length (4
我是新来的c#=) 我有一个关于udp socket的问题。 我有一个聊天服务器,接收数据包到特定的结构(udp数据报)。 为什么程序在套接字缓冲区已满时接收数据? 所有后来的事情都不应该丢失吗? 也许数据包碎片发生? 数据包结构:udp_headers(28字节)| dataIdentifier(4字节)|名称长度(4字节)|消息长度(4字节)|名称(名称长度)|消息(消息长度) 当我发送比内部缓冲区大的数据包时。 该程序引发异常: Rec
I'm writing a program to communicate with certain patient monitor using connection-less (UDP) sockets. I need a suggestion for the fastest and most efficient algorithm that I should use to parse the data received from patient monitor. Patient monitor sends data as AttributeList structure, the definition of the structure is below:- typedef struct { uint16 count; uint16 length; AVATyp
我正在编写一个程序,使用无连接(UDP)套接字与某个患者监视器进行通信。 我需要一个建议,用于解析从患者监护仪接收到的数据的最快和最有效的算法。 患者监护仪将数据作为AttributeList结构发送,结构的定义如下: - typedef struct { uint16 count; uint16 length; AVAType * values; } AttributeList; typdef struct { uint16 id; uint16 length; void * data; } AVAType 所以AttributeList包含许多AVATy
I'm making a C program that communicates with a patient monitor that uses big endian byte ordering. For example, if I've certain C structure typedef struct { int short a; int short b; int c; } msg; To read this kind of structure, I can simply use ntohs(msg.a), ntohs(msg.b), ntohl(msg.c). But some of the structure has a buffer of short integers but that buffer itself is
我正在制作一个C程序,与使用大端字节排序的患者监视器进行通信。 例如,如果我有一定的C结构 typedef struct { int short a; int short b; int c; } msg; 要阅读这种结构,我可以简单地使用ntohs(msg.a),ntohs(msg.b),ntohl(msg.c)。 但是一些结构有一个短整数的缓冲区,但缓冲区本身就是另一个结构的类型。 例如, typedef struct { int short length; int short b[MAX_BUF_SIZE]; } msg1;
I am trying to write server that will communicate with any standard client that can make socket connections (eg telnet client) It started out as an echo server, which of course did not need to worry about network byte ordering. I am familiar with ntohs, ntohl, htons, htonl functions. These would be great by themselves if I were transfering either 16 or 32-bit ints, or if the characters in th
我试图编写服务器,将与任何可以进行套接字连接的标准客户端通信(例如,telnet客户端) 它起初是一个回声服务器,当然这并不需要担心网络字节排序。 我熟悉ntohs,ntohl,htons和htonl函数。 如果我传输16位或32位整数,或者要发送的字符串中的字符是2或4字节的倍数,这些会很棒。 我想创建一个函数,对字符串进行操作,例如: str_ntoh(char* net_str, char* host_str, int len) { uint32_t* netp, hostp; netp
