i understand how retrieve data xml source using type providers. however, need modify particular part of xml , save disk. have tried assigning value node using <- property read-only. for example: let doc = myxml.load filename doc.itemid.id <- "newid" // doesn't work doc |> savexml there similar question json suggestion create new object, xml. while researching question found can use .xelement accessor reference mutable xelement object. solution is: let doc = myxml.load filename doc.itemid.xelement.element(xname.get "id").value <- "newid" // tada doc.xdocument.save(...) note have use .xelement accessor on parent if you're modifying leaf node. because leaf node's type primitive , doesn't have .xelement accessor of own. slight shame, suppose makes life easier on other side when want read-only access value.

i new ruby on rails. heard ruby on rails needs java virtual machine run. i ask basic stuff ruby on rails. it seems ruby on rails can have native code in source code. from have researched ruby on rails, code runnable on same platform code written. so when need run code on different platform, using bundler ( rubygems ), can automatically download right version of package. is correct?? also, packages, there packages or modules not written in pure ruby?? i not sure if there any. if there is, think package manager cannot automatically download right version , developers need pull out , make changes deploy on other machines. i wasn't sure how @ package dependencies in package. there way find package dependency?? it not clear question asking perhaps can resolve of confusion. rails framework, distributed ruby gem package runs part of ruby app on 1 of several available ruby interpreters. neither ruby nor rails depend on jvm. jruby interpreter allows run rub...

i need advice how send doubly linked list of connected users. basic information code , approach far: i keep information connected users in doubly linked list, shared among threads. store head of list in global variable : *pper_user g_userslist , , struct users like: typedef struct _user { char id; char status; struct _user *pctxtback; struct _user *pctxtforward; } user, *pper_user; when new user connects server, data connected users gathered linked list , send him: wsabuf wsabuf; pper_player ptemp1, ptemp2; unsigned int c=0; ..... entercriticalsection(&g_csuserslist); ptemp1 = g_userslist; while( ptemp1 ) { ptemp2 = ptemp1->pctxtback; wsabuf.buf[c++]=ptemp1->id; // fill buffer data users wsabuf.buf[c++]=ptemp1->status; // ptemp1 = ptemp2; }; wsasend(...,wsabuf,...); leavecriticalsection(&g_csuserslist); but few things code above makes me confused: the linked list rather under heavily usage other threads...

we planning use lucene.net search in order have google search. have huge amount of data loaded d/b needs indexed. there limitations on size of indexing documents , maximum size of single index document be? how distribute size on average size of each document? there no limitations data sizes you're hinting at, i'm running lucene.net app works 100s of gb of indexed data without spliting index (outside of how lucene naturally splits without asking). just add data index , forget limitations, you're way bellow potential issues. (but read performance guidelines, lucene ones lucene.net direct port, tips apply).

i trying query data using linq, joining 2 tables id == id of second table. getting exception error saying cannot implicitly convert type ' system.collections.generic.list<anonymoustype#1> ' ' system.collections.generic.list<--db table here--> '. var qry = context.projects .join(context.members, p => p.id, m => m.id, (p, m) => new { p, m }) .where(u => u.m.id == memid) .select(b => new { b.p.projname, b.p.projdesc, b.p.projecttype, b.p.tags }); return qry.tolist(); you trying return list of anonymous type method return type list<sometype> . so instead of creating anonymous objects need create objects of type. .select(b => new sometype { // set properties here });

recently use nsregularexpression me parse website's source. i found example expression @"(.*?)(<[^>]+>|\\z)" . kind people me out meaning of pattern? (.*?)(<[^>]+>|\z) - first part (.*?) non-greedy way of consuming characters, or in other words, consume minimum possible number of characters until reach next part: (<[^>]+>|\z) . (<[^>]+>|\z) - here have 2 parts, first part <[^>]+> - match expression starts < , has @ least 1 character before closing > . [^>] means character except > , + means number of characters >= 1. the | "or" - means matching group should match either first part <[^>]+> or second part \z means end of string.

i able send , receive udp messages in separate programs, i'm not able same task in 1 program. import socket udp_ip = "192.168.1.178" udp_port = 8888 msg = 'test' print "udp target ip: ", udp_ip print "udp target port: ", udp_port print "message: ", msg sock = socket.socket(socket.af_inet, socket.sock_dgram) sock.sendto(msg, (udp_ip, udp_port)) udp_ip2 = "192.168.1.198" sock.bind((udp_ip2, udp_port)) while true: data, addr = sock.recvfrom(1024) # buffer size 1024 bytes print "received message:", data with program, able send udp messages, however, not able receive messages other machine. what doing wrong? in advance, mikkel in example try bind socket addr after sending, what's wrong. address can bound socket before data transfer. if there no explicit bind os sets free (unused) port number in range [1024, 65535] on first .send()/.recv() call. next, socket can bound singl...
