• ASP/HTML problem with spaces and monofonts

  - by nickik

  I have a ASP has a Function that converts ä to &auml so far so good. I have lets say space for 10 char's if there are more cut them of if there are less fill the space up with &nbsp's. . Like this: test &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp but if i say "täst" it does this: te &auml t &nbsp It interprets the &auml not as one char it looks at it as 6 chars. Is there a clever way around that? This problem messes up my design because I need the right count of spaces. The whole thing goes into a big select box. Of you have to add a ; at the end of ever &... I could add them because the Editor would really interprt them.

• ASPNET MVC what do you call this, a partial view? Or something else?

  - by JK

  I'm trying to google for info on a situation, but I dont know what it is called, so its hard to find results :) I have a model with say 10 fields. But only some of those are shown on a particular view, lets say 3 of them: id, name, date. What do you call this kind of view that does not display the whole model? A partial view? The problem is that because 7 fields are not sent to the view, when the Update action is called on the controller, those fields are null, and the DB gets updated with those 7 fields set to null.

• MS Excel 03 - Deleting rows that have live string identifiers in column A, while concatenating other

  - by Justin

  I have this xml document that is provided as a data feed (right off the bat I can not modify the source of the data feed) and i import it into excel with the xml import. there is no schema that comes with this xml so i get a table that ends up having a whole bunch of duplicates for an identifier, because of the unique values spread throughout the spreadsheet. XML in XLS Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01 6B 0011 Item xxj9 7B 0011 Item xxj9 0011 Item 02 0011 Item 01 xxj9 6B 0012 etc I need to delete all rows where columnA string/number matches while concatenating all potential values from Col3, Col4 & Col5 together so it looks like this Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01, 02 xxj9 6B, 7B what visual basic method would allow me to accomplish this? thanks

• How to dynamically load and switch the resource file in the web app (ASP.NET) without recompiling ?

  - by Thomas Wanner

  I would like to store the resource files (containing texts for labels etc.) for my web application in the database to be able to edit and create them dynamically later (probably in the UI). My idea was to store the whole resx file in an xml column and simply load it on demand - depending on the language and some other attributes of the current user when he is logging into the application or switching the context. The important thing is that the resources do not only depend on the culture info of the user but also on some context information that can be switched by user without logging off and on again (in our case called "group", not having anything to do with a group of users). Is it possible somehow to load the contents of the resources from an external source and simply switch them without web application being recompiled by the server ? I know that there are some interfaces on which I could hook up and implement a custom resources provider which reads from the database directly but if it could work somehow with the resx files it would probably make things a lot easier..

• gprof and execl() - is it possible?

  - by Chris

  Background: I have a game (an old-school-esque MUD) which I've been attempting to profile with gprof. The documentation of gprof (on Linux 2.6) states that The profiled program must call "exit"(2) or return normally for the profiling information to be saved in the gmon.out file. Now, if I kill the server with the shutdown command, the application "returns normally" (i.e., main() returns) and I get a gmon.out to analyze. However, it's far more common to reboot the server. The reboot command does the following: Writes usernames and socket FD numbers to disc. Makes a call to execl(). The new process looks for the stored data, picks up the FDs, and moves on. I see the following error on the command line, as the whole process fails: Profiling timer expired ./program Question: Is it possible to get a gmon.out file from the execl()-calling process? Perhaps some environmental parameter to execl(), or else perhaps a different, gprof-friendly, system call to achieve the same effect (beginning a new process while preserving file descriptors)?

• PHP New Line will not work

  - by user364333

  Hi I am trying to create some code that first reads the existing contents of the file in and then adds the new line of code on a new line but the code i am using just adds it on the new text on to the already existing line instead of the new line... Here is the code i am using: <?php $id = $_GET['id']; $userfile = "user1.txt"; $fo = fopen($userfile, 'r') or die("can't open favourites file"); $currentdata = fread($fo, filesize($userfile)); fclose($fo); $fw = fopen($userfile, 'w') or die("can't open favourites file"); $currentprocessed = "$currentdata\n"; fwrite($fw, $currentprocessed); fwrite($fw, $id); fclose($fw); ?> I have tried a whole range of different ideas but nothing has worked, any help would be appreciated.

• How to reduce this IF-Else ladder in c#

  - by Rohit

  This is the IF -Else ladder which I have created to focus first visible control on my form.According to the requirement any control can be hidden on the form.So i had to find first visible control and focus it. if (ddlTranscriptionMethod.Visible) { ddlTranscriptionMethod.Focus(); } else if (ddlSpeechRecognition.Visible) { ddlSpeechRecognition.Focus(); } else if (!SliderControl1.SliderDisable) { SliderControl1.Focus(); } else if (ddlESignature.Visible) { ddlESignature.Focus(); } else { if (tblDistributionMethods.Visible) { if (chkViaFax.Visible) { chkViaFax.Focus(); } else if (chkViaInterface.Visible) { chkViaInterface.Focus(); } else if (chkViaPrint.Visible) { chkViaPrint.Focus(); } else { chkViaSelfService.Focus(); } } } Is there any other way of doing this. I thought using LINQ will hog the performance as i have to tranverse the whole page collection. I am deep on page which has masterpages.Please suggest.

• Javascript: setTimeout() - help needed

  - by ilkin

  Hi guys, I'm currently doing a highlighting function on a webpage and im using the jquery plugin for that. My code looks like this: var input = function() { var matchword = $('#searchbox').val(); if(matchword != "") { $('body').removeHighlight(); $('body').highlight($('#searchbox').val()); } } $(document).ready(function() { $('#searchbox').keyup(function() { setTimeout("input()", 2000); }); }); It works fine if there is not so large amount of data on the page. But in case of large amount of data on the page the whole process is slowing down which causes that inputbox is freezing untill the letter is hightlighted. So the typing is not smooth. I tryed to use a setTimeout but it seems doesnt help. Any ideas?

• Virtual String Tree - Display subnode when parent node is hidden

  - by daemon_x

  Is there a way to show subnode if the parent node is hidden in the Virtual String Tree ? I have some tasks in the tree structure and I wish to display only tasks which belongs to the current user as the list, but from all levels. What I've done is the function to display a list, which hides tree buttons, tree lines, sets the fixed indent and enable toShowHiddenNodes option. Then in this function I iterate through the whole tree (all levels) and hide nodes which doesn't belong to the current user IsVisible[Node] := False and show those which belongs him IsVisible[Node] := True, but the subnodes which should be displayed are invisible when their parent is hidden. VT.TreeOptions.PaintOptions - toShowButtons - toShowTreeLines + toFixedIndent + toShowHiddenNodes

• Should member variables of global objects be made global as well?

  - by David Wong

  I'm developing plugins in Eclipse which mandates the use of singleton pattern for the Plugin class in order to access the runtime plugin. The class holds references to objects such as Configuration and Resources. In Eclipse 3.0 plug-in runtime objects are not globally managed and so are not generically accessible. Rather, each plug-in is free to declare API which exposes the plug-in runtime object (e.g., MyPlugin.getInstance() In order for the other components of my system to access these objects, I have to do the following: MyPlugin.getInstance().getConfig().getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); , which is overly verbose IMO. Since MyPlugin provides global access, wouldn't it be easier for me to just provide global access to the objects it manages as well? MyConfig.getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); Any thoughts? (I'm actually asking because I was reading about the whole "Global variable access and singletons are evil" debates)

• How to store a 250mb database in an Offline Web App

  - by Couto

  Ok, maybe i'm not seeing the whole picture or something, but i kinda need a brainstorm. So the purpose is to make a webapp (HTML5, CSS, Javascript) that has to search on a 250mb database without any internet connection, so.. yes the database has to be on the client side. The hard part here is, this App has to work on an iPod or iPhone without internet connection. (An initial connection to download the App is ok), LocalStorage has a 5mb limit, couchDB would be great since they have an webapp easily accessed by Javascript (privacy concerns don't matter at this point), so i'm pretty much out of ideas.... Does anyone see an alternative, or solution for the purpose?

• Which database should I use for best performance

  - by _simon_

  Hello, I am working in Visual Studio 2005, .NET 2.0. I need to write an application, which listens on COM port and saves incoming data to a database. Main feature: save incoming data (series of 13-digits numbers), if this number allready exists, then mark it as double. For example, there could be these records in database: 0000000000001 OK 0000000000002 OK 0000000000002 Double 0000000000003 OK 0000000000004 OK I could use SQL database, but I don't know if it is fast enough... Database should be able to store up to 10.000.000 records and write up to 100 records per minute (so it needs to check 100 times per minute if this record allready exists). Which database should I use? Maybe the whole database would need to be in RAM. Where could I learn more about this? Thanks

• Bit/Byte adressing - Little/Big-endnian

  - by code8230

  Consider the 16-Bit data packet below, which is sent through the network in network byte order ie Big Endian: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 (Byte num) 34 67 89 45 90 AB FF 23 65 37 56 C6 56 B7 00 00 (Value) Lets say 8945 is a 16 bit value. All others are 8 bit data bytes. On my system, which is little endian, how would the data be received and stored? Lets say, we are configured to receive 8 bytes at a time. RxBuff is the Rx buffer where data will be received. Buff is the storage buffer where data would be stored. Please point out which case is correct for data storage after reading 8 bytes at a time: 1) Buff[] = {0x34, 0x67, 0x45, 0x89, 0x90, 0xAB....... 0x00}; 2) Buff[] = {0x00, 0x00, .......0x67, 0x89, 0x45, 0x34}; Would the whole 16 bytes data be reversed or only the 2 bytes value contained in this packet?

• how to start writing a very simple programming language

  - by Rex Homming

  Recently, I was going around looking for ideas on what I can build using C this summer and I came across this post: http://stackoverflow.com/questions/1257376/interesting-project-to-learn-c Implement a programming language. This doesn't have to be terribly hard - I did the language that must not be named - but it will force you to learn a lot of the important parts of C. If you don't want to write a lexer and/or parser yourself, you can use lex/flex and yacc/bison, but if you plan on that you might want to start with a somewhat smaller project. I was kinda intrigued about the implementing a programming language answer and I'm wondering how do I go about starting this? I've gone through the whole K&R book and I've done some of the exercises as well. I also have a bit of experience in C++ and Java if that matters. Any tips? Thanks!

• Working with Foreign languages

  - by Matt

  My DB needs to hold strings containing foreign language characters such that; User enters string into form, form submitted and string added to DB, string will be displayed on page for viewing. I would like to use UTF8 as this will be able to handle all of the required languages. Currently I believe my DB is set to 'latin1' but webpages are capable of displaying correct charachters anyways. Problems arise when trying to set textareas to hold foreign charachters and when viewing DB via command-line. How can I implement this most effectively? My plan was to blitz the whole site such that:DB Charset is UTF8 and web pages charset is UTF8. Could someone give me the minimal commands on how to do this so I don't end up duplicating things (Having "UTF8" commands everywhere when I really just need one) and making things too difficult to control. Newbie Thanks

• Quick way to get an NSDictionary from an XML NSData representation?

  - by dontWatchMyProfile

  I've loaded an XML file as NSData into memory and parse over the elements using NSXMLParser. Although it works, it's a very ugly and hard to maintain code since there are about 150 different elements to parse. I know there are nice third-party solutions, but I want to keep it with the iPhone SDK for purpose of practice and fun. So I thought: Why not convert that XML file into an NSDictionary? Having this, I could use fast enumeration to go over the elements. Or is it just the same amount of ugly code needed to parse and process an XML right away with NSXMLParser? Would I build up an NSDictionary for every found node in the XML and create a huge one, containing the whole structure and data? Or is there an even simpler way?

• Reloading Rails Directories on Change for Development, Not in Lib

  - by yar

  I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.

• Java - Optimize finding a string in a list

  - by Mark

  I have an ArrayList of objects where each object contains a string 'word' and a date. I need to check to see if the date has passed for a list of 500 words. The ArrayList could contain up to a million words and dates. The dates I store as integers, so the problem I have is attempting to find the word I am looking for in the ArrayList. Is there a way to make this faster? In python I have a dict and mWords['foo'] is a simple lookup without looping through the whole 1 million items in the mWords array. Is there something like this in java? for (int i = 0; i < mWords.size(); i++) { if ( word == mWords.get(i).word ) { mLastFindIndex = i; return mWords.get(i); } }

• Is there any tool which can show the call tree for SQL stored procedures

  - by DBZ_A

  I have a huge SQL script which i need to analyse. It would be really helpful if i could find a tool which can generate a call tree; ie, to see which all procedures are called from a particular procedure. a perl based example is here, http://sqlblog.com/blogs/linchi_shea/archive/2009/10/23/find-the-complete-call-tree-for-a-stored-procedure.aspx but i need a tool to analyse the text file (.sql file), not the procedure stored in the database. due to some reasons i will not be able to create the whole set of procedures in the database and use the above mentioned tool. please respond if you have come across any ide/tool with this feature.

• So I dynamically load a jar at runtime how do I use it?

  - by justinhj

  So question 194698 shows how to load a jar file at runtime and you can load individual named classes and get a Class object. Now my problem is I want to be able to cast those Classes to the types they really are, but I can't because I can't use an import since the whole point is to load it at runtime rather than compile time. It seems like the way to go is to use reflection to discover the functions and field names, but that seems brittle since the API in the jar files could change and the code won't break until it is run. Is there a better way?

• Looking for an array (vs linked list) hashtable implementation in C

  - by kingusiu

  hi, I'm looking for a hashtable implementation in C that stores its objects in (twodimensional) arrays rather than linked lists. i.e. if a collision happens, the object that is causing the collision will be stored in the next free row index rather than pushed to the head and first element of a linked list. plus, the objects themselves must be copied to the hashtable, rather than referenced by pointers. (the objects do not live for the whole lifetime of the program but the table does). I know that such an implementation might have serious efficiency drawbacks and is not the "standard way of hashing" but as I work on a very special system-architecture i need those characteristics. thanks
