• Asp.net (c#) and a JEE 5 webservice

  - by arinte

  We have a asp.net app that talks to a pretty complex JEE 5 web service. Everything works fine except when we throw an exception. We throw a simple exception without any inner/orig exception, but we get this message on the .Net side. Additional XML content is present in the fault detail element. Only a single element is allowed. Works fine with a java client, as in we can get the exception message. What can we do?

• can oracle types be updated like tables?

  - by Omnipresent

  I am converting GTT's to oracle types as explained in an excellent answer by APC. however, some GTT's are being updated based on a select query from another table. For example: UPDATE my_gtt_1 c SET (street, city, STATE, zip) = (SELECT src.unit_address, src.unit_city, src.unit_state, src.unit_zip_code FROM (SELECT mbr.ROWID row_id, unit_address, RTRIM(a.unit_city) unit_city, RTRIM(a.unit_state) unit_state, RTRIM(a.unit_zip_code) unit_zip_code FROM table_1 b, table_2 a, my_gtt_1 mbr WHERE type = 'ABC' AND id = b.ssn_head AND a.h_id = b.h_id AND row_id >= v_start_row AND row_id <= v_end_row) src WHERE c.ROWID = src.row_id) WHERE state IS NULL OR state = ' '; if my_gtt_1 was not a global temporary table but an oracle collection type then is it possible to do updates this complex? Or in these cases we are better off using the global temporary table?

• Matching of tuples

  - by Jack

  From what I understood I can use pattern-matching in a match ... with expression with tuples of values, so something like match b with ("<", val) -> if v < val then true else false | ("<=", val) -> if v <= val then true else false should be correct but it gives me a syntax error as if the parenthesis couldn't be used: File "ocaml.ml", line 41, characters 14-17: Error: Syntax error: ')' expected File "ocaml.ml", line 41, characters 8-9: Error: This '(' might be unmatched referring on first match clause.. Apart from that, can I avoid matching strings and applying comparisons using a sort of eval of the string? Or using directly the comparison operator as the first element of the tuple?

• Lock HTML select element, allow value to be sent on submit

  - by ILMV

  I have a select box (for a customer field) on a complex order form, when the user starts to add lines to the order they should not be allowed to change the customer select box (unless all lines are deleted). My immediate thought was that I could use the disabled attribute, but when the box is disabled the selected value is no longer passed to the target. When the problem arose a while ago one of the other developers worked around this by looping through all the options and disabling all but the selected option, and sure enough the value was passed to the target and we've been using since. But now I'm looking for a proper solution, I don't want to loop through all the options because are data is expanding and it's starting to introduce performance issues. I'd prefer not to enable this / all the elements when the submit button is hit. How can I lock the input, whilst maintaining the selected option and passing that value to the target script? I would prefer a non-JavaScript solution if possible, but if needed we are running jQuery 1.4.2 so that could be used.

• when to use strncpy or memmove

  - by robUK

  Hello, gcc 4.4.4 c89 I have always used strncpy to copy strings. I have never really used memmove or memcpy very much. However, I am just wondering when would you decide whether to use strncpy, memmove, or memcpy? The code I am writing is for a client/server application. In the documentation they use bcopy. However, could I do the same with the others? bcopy((char*)server->h_addr, (char*)&serv_addr.sin_addr.s_addr, server->h_length); Many thanks,

• Web UI for showing like/dislike community comments side-by-side

  - by Justin Grant

  We want to add a comments/reviews feature to our website's plugin gallery, so users can not only vote up or down a particular plugin, but also leave an optional short comment about what they liked or didn't like about it. I'm looking for inspiration, ideally a good implementation elsewhere on the web which isn't annoying to end users, isn't impossibly complex to develop, and which enables users to see both good and bad comments side-by-side, like this: Like: 57 votes Dislike: 8 votes --------------------------------- -------------------------------- "great plugin, saved me hours..." "hard to install" "works well on MacOS and Ubuntu" "Broken on Windows Vista with UAC enabled" "integrates well with version 3.2" More... More... Anyone know a site which does something like this?

• AMF through a BinarySocket written in .net

  - by KensoDev

  Hi All, I have a windows service behaving as a Binary Socket sending data to flex applications. Once I try to send strings or int's or any other native data-type, everything is working great. I even succeeded in sending JSon from the server to the client parsing it on Flex. I want to send AMF objects to the client. Meaning, I have a class called User, I want to fill it with data and send it to the client, there I want it to be mapped to an object on the client. How can I achieve this?

• Java's TreeSet equivalent in Python?

  - by viksit

  I recently came across some Java code that simply put some strings into a Java TreeSet, implemented a distance based comparator for it, and then made its merry way into the sunset to compute a given score to solve the given problem. My questions, Is there an equivalent data structure available for Python? The Java treeset looks basically to be an ordered dictionary that can use a comparator of some sort to achieve this ordering. I see there's a PEP for Py3K for an OrderedDict, but I'm using 2.6.x. There are a bunch of ordered dict implementations out there - anyone in particular that can be recommended? Thanks.

• Migrating shape sql to something equally powerful

  - by daRoBBie

  Hi, we are currently investigating a migration of an application that doesn't meet company standards. The application is built using VB6 and Shape SQL/Access. The application has about 120 reports by storing Shape SQL strings in a database which the user can modify using a wizard. Shape sql is not allowed at this company. We have investigated plain SQL, Linq, Entity Framework as alternatives... but all result in more complex solutions. Does anyone have another suggestion? Update: Shape SQL is an ADO command to get hierarchical datasets, for further info: http://support.microsoft.com/kb/189657

• Multiple delimiters using Regex.Split in C#

  - by Arthur Frankel

  Let's say you need to split a string by various delimiters including newline (/r, /n) and a few other 'special' character strings. For example: This is a sample %%% text &&& that I would like to split %%% into an array. I would like the following in the resulting string array (contents via index) [0]This is a sample [1]text [2]that I would [3]like to split [4]into an array. I would like to use C# Regex.Split() function. What is the regex expression to match on all of my delimiters? Thanks in advance

• Comparing two java objects on fly (data type not known)

  - by Narendra

  Hi All, I need to compare different data objects. Can any one tell me how can i do this. I don't know what are the data types i will get priorly. If i need to use any util from apache commons then please give reference to it. At present I am using .equals() for comparing equality of objects .It is working fine when I am comparing quality for two strings. If i am comparing java.sql.date data type then it is showing unequal even though both contains same values. Can any one suggest me on this regard. Thanks, Narendra

• Folders-like URL with PHP?

  - by Maxime

  Hi, ever since I added this htaccess to my website, I noticed a HUGE slowdown, and my error logs are filled with errors such as PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in page.php on line 79. I've got up to four of these per second. Most of the time it works though. The htaccess consisted of two similar rules: one with two GET vars, another one with only one. RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)\/(.*)$ index.php?var1=$1&var2=$2 [L] Anyway, I just rewrote a PHP script that handles of all the strings and redirects where it should, and my website is now fast again. But is there a way to hide mypage.php?var1=la&var2=lu and still have URLs that look like folders? Thanks for your replies!

• How do you verify the correct data is in a data mart?

  - by blockcipher

  I'm working on a data warehouse and I'm trying to figure out how to best verify that data from our data cleansing (normalized) database makes it into our data marts correctly. I've done some searches, but the results so far talk more about ensuring things like constraints are in place and that you need to do data validation during the ETL process (E.g. dates are valid, etc.). The dimensions were pretty easy as I could easily either leverage the primary key or write a very simple and verifiable query to get the data. The fact tables are more complex. Any thoughts? We're trying to make this very easy for a subject matter export to run a couple queries, see some data from both the data cleansing database and the data marts, and visually compare the two to ensure they are correct.

• First programming language: PHP, Ruby, Python?

  - by Victor

  I've been a Web developer for over 5 years and am looking to start building more complex Web apps. Currently, I know HTML/CSS/Javascript but I feel it's time to start learning something else. I work with a lot of applications based on PHP. I created a vBulletin forum on my own time and I would definitely want to build off of that since it has gained a bit of popularity. I also work with Wordpress quite often. All of the software I work with tends to be based on PHP but I hear a lot of people say Ruby or Python is better. Since I'm starting out, I really don't care which one I learn but I want to start right. Any recommendations for someone with HTML/CSS/Javascript knowledge but wants to branch out?

• How do you make an in-place construction of a struct casted to array compile in Visual C++ 2008?

  - by Irwin1138

  I'm working with quite a big codebase which compiles fine in linux but vc++ 2008 spits errors. The problem code goes like this: Declaration: typedef float vec_t; typedef vec_t vec2_t[2]; The codebase is littered with in-place construction like this one: (vec2_t){0, divs} Or more complex: (vec2_t){ 1/(float)Vid_GetScreenW(), 1/(float)Vid_GetScreenH()} As far as I know, this code constructs a struct, then converts it to an array and passes the address to the function. I personally never used in-place construction like this so I have no clue how to make this one work. I don't maintain the linux build, only the windows one. And I can't get it to compile. Is there some switch, some macro to make vc++ compile it? Maybe there is a similar nifty way to construct those arrays and pass them to the functions in-place that compiles just fine in vc++?

• How to easily pass a very long string to a worker process under Windows?

  - by sharptooth

  My native C++ Win32 program spawns a worker process and needs to pass a huge configuration string to it. Currently it just passes the string as a command line to CreateProcess(). The problem is the string is getting longer and now it doesn't fit into the 32K characters limitation imposed by Windows. Of course I could do something like complicating the worker process start - I use the RPC server in it anyway and I could introduce an RPC request for passing the configuration string, but this will require a lot of changes and make the solution not so reliable. Saving the data into a file for passing is also not very elegant - the file could be left on the filesystem and become garbage. What other simple ways are there for passing long strings to a worker process started by my program on Windows?

• Will GTK's pango and cairo work well in Cocoa and MFC applications.

  - by Lothar

  I'm writing a GUI program and decided to go native on all platforms. But for all the stuff i need to draw myself i would like to use the same drawing routines because font and unicode handling is so difficult and complex. Do you see any negative points in useing Pango/Cairo. Well on MacOSX i havent succeded installing Pango/Cairo yet. Looks like a bad Omen. I would also like to hear about the performance penality. The first time i looked at Pango i thought, yes thats the reason why Software is still getting despite better hardware.

• Do I need to sanitize the callback parameter from a JSONP call?

  - by christian studer

  I would like to offer a webservice via JSONP and was wondering, if I need to sanitize the value from the callback parameter. My current server side script looks like this currently (More or less. Code is in PHP, but could be anything really.): header("Content-type: application/javascript"); echo $_GET['callback'] . '(' . json_encode($data) . ')'; This is a classic XSS-vulnerability. If I need to sanitize it, then how? I was unable to find enough information about what might be allowed callback strings.

• Is Lightweight Code Generation (LCG) dead?

  - by Greg Beech

  In the .NET 2.0-3.5 frameworks, LCG (aka the DynamicMethod class) was a decent way to emit lightweight methods at runtime when no class structure was needed to support them. In .NET 4.0, expression trees now support statements and blocks, and as such appear to provide sufficient functionality to build just about any functionality you could require from such a method, and can be constructed in a much easier and safer way than directly emitting CIL op-codes. (This statement is borne from today's experimentation of converting some of our most complex LCG code to use expression tree building and compilation instead.) So is there any reason why one would use LCG in any new code? Is there anything it can do that expression trees cannot? Or is it now a 'dead' piece of functionality?

• sorting content of a text file in python

  - by rabidmachine9

  I have this small script that sorts the content of a text file # The built-in function `open` opens a file and returns a file object. # Read mode opens a file for reading only. try: f = open("tracks.txt", "r") try: # Read the entire contents of a file at once. # string = f.read() # OR read one line at a time. #line = f.readline() # OR read all the lines into a list. lines = f.readlines() lines.sort() f = open('tracks.txt', 'w') f.writelines(lines) # Write a sequence of strings to a file finally: f.close() except IOError: pass the only problem is that the text is displayed at the bottom of the text file everytime it's sortened... I assume it also sorts the blank lines...anybody knows why? thanks in advance

• vb.net - how do I parse a percentage value from a grid cell?

  - by Bob Palin

  I'm trying to parse a formatted percentage value back from a datagridviewcell that has been set with the "P" formatter: double percent = 0.96 cell.value = percent.tostring("p") gives me a displayed value of 96 % which is what I want. Now what I'm looking for is something like what is provided for the other formatting strings - NumberStyles.HexNumber, Currency etc so that I can do this double percent= double.parse( cell.value, NumberStyles.Percent ) which would give me a percent value of .96 I have scoured the .net documentation but can't find any sort of AllowPercent style like the others - is there one? Bob Palin p.s. I see there is another question here like this and tried to expand on it in that thread, but was deleted by a moderator and told to post a new question.

• How to execute statements in order in objective c

  - by Vu Tu?n Anh

  When i tap on my button, my function was called [myBtn addTarget:self action:@selector(myFunction) forControlEvents:UIControlEventTouchUpInside]; In my function, a collection of complex statement will be executed and take a litte bit time to run, so i want to show Loading (UIActivityIndicatorView) as the following: -(void) addTradeAction { //Show Loading [SharedAppDelegate showLoading]; //disable user interaction self.view.userInteractionEnabled = NO; //execute call webservice in here - may be take 10s //Hide Loading [ShareAppDelegate hideLoading]; } When tap on myBtn (my Button) - after 3s or 4s, [ShareAppDelegate showLoading] was called. It is unusual when i use [ShareAppDelegate showLoading] on other Function, - it work very nice, i mean all the statement be executed in order. All i want, when i tap on My Button, Loading will be called immediatelly. Tks in advance
