-
i need write application using c#, connect client server static ip address. the server , clients must able send , receive message @ same time. also, need log information respect of clients public address well. how can make using c#? shall use tcplistener / tcpclient or there other method can make multiple connections? if want go low level tcp/ip , own message parse/serialize/deserialize, can use socketasynceventargs high performance code, not easy tcplistener/tcpclient. http://msdn.microsoft.com/en-us/library/vstudio/system.net.sockets.socketasynceventargs http://www.codeproject.com/articles/83102/c-socketasynceventargs-high-performance-socket-cod question is, why not use example wcf/iis ?

testing - How to compile and run QTP script from command line -

-
i want use text file containing source code of qtp script, , compile (create usr,cfg,usp etc files created when manually "save" script in qtp) using command line. there way both? all files in qtp/uft when you're doing "more" writing script. stores test description, associated repositories, parameters, recovery scenarios, etc. if you're writing test logic in text file, there's chance you're not using of stuff either. take blank qtp/uft test create "template" of valid test. have replace 'action1/script.mts' file contents of text file. if want of command-line, you'll need write simple console-based application heavy lifting you.

python - What is wrong with this ternary operator? -

-
for in str1: (newstr += chr(ord(i)+2)) if i.isalpha() else (newstr += i) it seems grieving += operator. know both variables strings though, don't understand why not concatenate them try following: for in str1: newstr += (chr(ord(i)+2) if i.isalpha() else i) edit : from python documentation : conditional_expression ::= or_test ["if" or_test "else" expression] expression ::= conditional_expression | lambda_expr and pointed @flornquake, assignment var += value statement, not expression.

vb.net - Project to project reference - type not CLS compliant -

-
i have problem regarding public declaration in 1 project makes reference class in different project. the parent project references dependent project without problem. however, i'm getting warning type member 'user' not cls-compliant. it's declared public user user this declaration made in parent project. user class in supporting project can use type on form without fail. now, try pass off on form - in parent project: private olduser user olduser = frmusermgt.user and thing crashes. stepping through code shows olduser nothing. i built brand new solution , tested exchange without fail. i've searched solution , project settings until i'm blue in face , can't find difference. it's vs2012 vb solution. can post code needed if above description isn't sufficient - appreciated.

php - Generate ID based on file and line in (or something similar) -

in program need way create unique identifiers (like hash). important ids not random, same between calls same function or method. thus, if in line in file generated identifier xyz , in place should generated same identifier. i use code such instruction: $id = sha1(__file__ . __ line__); but not enough comfortable. i'd prefer use function or macro in c/c++ (i know php not have macros) follows: $id = generate_id(); the generate_id implemented below. works fine, i'm not convinced use function debug_backtrace in production code. maybe there's better solution? function generate_id() { $backtrace = debug_backtrace(); return sha1($backtrace[0]['file'] . $backtrace[0]['line']); } if intention have repeatable hash based on file, php has md5_file() method should need. $file = 'myfile.txt'; echo 'md5 file hash of ' . $file .

python - Mix of scalars, tuples and numpy arrays as string argument -

-
i using python generate povray rendering code visualization of computed data. need pass lot parameters python strings of povray code. make scrips cleaner. use tuples , arrays directly arguments string formating. this: sign = -1 name = "temp1" nu = 0.245 boxmin =(0.01,0.01,0.01) # tuple boxmax =array([0.99,0.99,0.99]) # array povfile.write( ''' isosurface { function { %f*( %f - data3d_%s(x,y,z) ) } contained_by { box { <%f,%f,%f>,<%f,%f,%f> } } }''' %( sign, nu, name, *boxmin, *boxmax ) ) instead of this: povfile.write( ''' isosurface { function { %f*( %f - data3d_%s(x,y,z) ) } contained_by { box { <%f,%f,%f>,<%f,%f,%f> } } }''' %( sign, nu, name, boxmin[0],boxmin[1],boxmin[2], boxmax[0],boxmax[1],boxmax[2] ) ) supposing every element want write in string list (or iterable) - if constituted 1 element - can use workaround based on list flattening.

android - Call an Activity method from inside adapter? -

-
i have custom adapter has click listener on listview image. this code inside adapter getview: holder.iconimage.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { //code stuff when image clicked } my images in listview consist of images of folders (to represent folder) , actual images. so if user clicks on folder image, want able call method called "movedownfolder" in activitya. i'm not sure if can done inside of adapter? [edit] in activitya have click listener on custom listview, if click on text in custom listview, moves down folder (if folder). but can click on image in listview, opens image in new activity. if click on folder icon in listview (which image of course in imageview) - want code move down folder, instead of trying open image. i recommending on using interface listener. for example: 1, create interface: public interface mylistener { void folderclicked

python - to_excel on desktop regardless of the user -

is there way use pandas to_excel function write desktop, no matter user running script? i've found answers vba nothing python or pandas. pandas.dataframe.to_excel() requires argument excel_writer either file path or existing excelwriter-object. just give path argument: >>> df.to_excel('path_to_your_file.xls') more specifically, write users desktop, use os.path.expanduser : >>> path = os.path.join(os.path.expanduser("~"), "desktop", "your_file.xls") >>> df.to_excel(path) os.path.expanduser guarantees you'll home directory of user on posix , windows there many corner cases should take account. for example on windows, if users home directory managed via active directory, you'll home directory resides on network drive, , there might not desktop -folder. similarily linux users have free hands rename or delete folder called desktop . or might not have desktop folder, linux doesn't

i have built countless angular-powered, find-as-you-type-style searches on past year or so, , love how easy implement. however, 1 problem i've never found solution how sort search results. appreciate has ideas on how this. here's problem : please see this plunker reference if @ super-simple example plunker above, have list of sample pets want able search through. if type text field, list of pets gets narrowed down. great. problem, search results aren't sorted in relation how similar text entered. for example : there total of 8 pets in list, sorted name using orderby:'name' filter on list's ng-repeat directive. if type character t input, 5 remaining results. pet @ top of list "blackie" (because blackie first pet in list has t in it, because blackie's type "cat", contains t ). what see way sort remaining results similarity search text. so, in example above, instead of seeing "blackie" @ top of list,

(date sorting slows down, instant without sort) but day starts takes long , longer run, ends taking > 2 minutes run. what noticed query seems lot of object/page locks when executed. what don't understand why acquiring locks while set read uncommitted. one of index's query uses set use row/page locking. my q: does index set use row/page locks, cause data locked when being accessed, when query read uncommitted? read uncommitted isolation level changes behaviour of readers only. in read committed , higher isolation level, when task tries read row, forst asks lock manager shared lock on it. request honored if there no existing exclusive lock on other session, otherwise have wait it. in read uncommitted reader not request shared lo
