Small solution to the call process of the modal dialog box in MFC

First, domodal () uses the dialog box Template NameProgramFind, load, and lock the dialog template in the resource file. If domodal () cannot locate the resource, an error is returned.Code-1; Then, this function will call premodal (). Premodal performs some security checks, and then searches for the parent handle for the dialog box (through cwnd: getsafeowner ). Save the result in m_hwnd.Then, it will call enabledwindow (false) to freeze the parent window, forced mode ~; Then, he will paste

Common Internet Router Protocol classifications

all, for Internet networks, no more than 1% of the machines need to be received at any one time in a multicast application. Sparse mode defaults All machines do not need to receive multicast packets, only explicitly specify the need to be forwarded, this can really apply to the "sparse" considerations. The main forwarding idea of all sparse-mode protocols now is that all of the same messages are forwarded in the same path, that is, first sent to a converging point (or kernel), and then forwarde

redirection, IP routing, and other technologies. In 2009, Microsoft released its security report (Advisory 973811), which provided two mechanisms: service binding and channel binding. Service-binding requires the client to provide the signed SPN into the authorization information. If an attacker attempts to use a certificate obtained from linked information or does not provide a signed SPN, it will not be able to connect to SQL Server, which has little performance impact. Channel binding provid

Detailed description of multicast addresses

IANA has allocated the Class D address space to the IP multicast address. the address of the Class D space is located in the first four digits of the first byte and identified by the binary value 1110. therefore, the multicast address range is: 224.0.0.0 to 239.20.00000000d Class address: www.2cto.com byte 1 byte 2 byte 3 byte 41110 xxxx xxxxxxxxThe principle is as follows: the address of the space is expressed in binary and the first four digits of the first eight digits are represented in 1110

That is to say, most subnets in the network contain at least one multicast group member, and the network bandwidth is large enough, this multicast routing protocol is called "intensive Mode" Dense-Mode). It relies on broadcast technology to push data to all routers in the network. Intensive mode Routing protocols include the Distance Vector Multicast Routing Protocol DVMRP: Distance Vector Multicast Routing Protocol) and the M
