• Excel VBA : Changing string in cells

  - by user1265125

  I have cells with data like these: ABCD123XYZ MPOP345MLU . . . . What I want to do is, to remove the 3rd and 4th character from all these cells, hence giving AB123XYZ MP345MLU How do I do this in VBA? I have no idea about this language, and if someone can guide me in the right direction, it'd be great :) I understand I have to: 1. Declare 2 string variables st1 and st2 2. Store data from cell A1 into the variable st1 3. Copy all but the 2nd and 3rd char into str2 4. Output Str2 into B1 5. Move to A2

• android localization: Is it a good practice to have only needed resource to put in localized folder?

  - by MobileDev123

  Hi, My application has 4 languages in it. However only one module needs to be localized out of 5, This module has 4 layout files and some images, remaining files can be there in default layout folder and drawable folders. My question is : is it good practice to put only needed files in localization folders, if I leave other files in its respective folders and don't copy them in translation folders, does my application throw NullPointerException when my application runs in other language? and Does android market have any size limit? (Also being a BB developer,AFAIK they do not allow OTA, if the application size grows more than 3 mb) [In case i need to copy the layout and image files]. Note about NullPointerException : it throws in string if you omit some string in localization and application runs in that particular locale. Thanks

• Need suggestions on which web frameworks to use?

  - by satish

  I want to build a site where people can create their personal websites quickly. All their websites will be hosted on my single web application (i.e. there will be only one database which contains info of all the websites). Each person will have an account where he can customize his website (template, content etc.). They can access their website from .mysite.com or mysite.com/xyz. I should be able to add different modules frequently, which will immediately reflect in all the websites created through my site. Based on the above requirements, please suggest me if there are any frameworks to use which can ease my job. Also suggest me which language to use (php or java). Which one would be better.

• Is it possible to build this type of program in PHP?

  - by Steven

  I want to build a QA program that will crawl all the pages of a site (all files under a specified domain name), and it will return all external links on the site that doesn't open in a new window (does not have the target="_blank" attribute in the href). I can make a php or javascript to open external links in new windows or to report all problem links that don't open in new windows of a single page (the same page the script is in) but what I want is for the QA tool to go and search all pages of a website and report back to me what it finds. This "spidering" is what I have no idea how to do, and am not sure if it's even possible to do with a language like PHP. If it's possible how can I go about it?

• How can I declare a pointer structure using {}?

  - by Y_Y

  This probably is one of the easiest question ever in C programming language... I have the following code: typedef struct node { int data; struct node * after; struct node * before; }node; struct node head = {10,&head,&head}; Is there a way I can make head to be *head [make it a pointer] and still have the availability to use '{ }' [{10,&head,&head}] to declare an instance of head and still leave it out in the global scope? For example: //not legal!!! struct node *head = {10,&head,&head};

• Using read in bash without empty fields collapsing

  - by Charles Duffy

  I'm trying to read a multi-line tab-separated file in bash. The format is such that empty fields are expected. Unfortunately, the shell is collapsing together field separators which are next to each other, as so: # IFS=$'\t' # read one two three <<<$'one\t\tthree' # printf '<%s> ' "$one" "$two" "$three"; printf '\n' <one> <three> <> ...as opposed to the desired output of <one> <> <three>. Can this be resolved without resorting to a separate language (such as awk)?

• Strange hex formatting in NSString

  - by pseudopeach

  Try this: unsigned long long int N; = 23229877463LL; NSString* s = [NSString stringWithFormat:@"dec:%qi, hex:%qX",N,N]; NSLog(@"output: %@",s); output: dec:23229877460, hex:689BCCD400000005 What's up with the 00000005??? In mySQL, hex(23229877460) = 5689BCCD4. Also, every other language seems to do this correctly. A 16 digit long hex is like 4 gazillion (16^16), right? How can I get objective-c to format hex numbers that other languages can understand?

• Problem with Xcode and iPhone preference files

  - by CyDummy

  Hi, I created four language files for my app: two for the preferences and two for the strings. I added them into Xcode and it works great on the phone but the string files are shown as "Localizable.strings (de)" and "Localizable.strings (en)", while I have two files called "Root.plist" under the "Settings.bundle" in the groups "de.lproj" and "en.lproj" (see screenshot).When I don't add the two "Root.plist" files instead of "Settings.bundle", I get what I want ("Root.plist (de)" and "Root.plist (en)") but I have no "Settings.bundle" in Xcode. Is somebody out there who can help me to a get what I want?

• MVC Pages that require the user to be logged in

  - by keithjgrant

  I'm working on a little MVC framework and I'm wondering what the "best way" is to structure things so secure pages/controllers always ensure the user is logged in (and thus automatically redirects to a login page--or elsewhere--if not). Obviously, there are a lot of ways to do it, but I'm wondering what solution(s) are the most common or are considered the best practice. Some ideas I had: Explicitly call user->isLoggedIn() at the beginning of your controller action method? (Seems far too easy to forget and leave an important page unsecure on accident) Make your controller extend a secureController that always checks for login in the constructor? Do this check in the model when secure information is requested? (Seems like redundant calls would be made) Something else entirely? Note: I'm working in PHP, though the question is not language-dependent.

• C++ corrupt my thinking, how to trust auto garbage collector?

  - by SnirD

  I use to program mainly with C/C++, that's make me dealing with pointers and memory management daily. This days I'm trying to develop using other tools, such as Java, Python and Ruby. The problem is that I keep thinking C++ style, I'm writing code as C++ usually written in almost every programming language, and the biggest problem is the memory management, I keep writing bad code using references in Java and just get as close as I can to the C++ style. So I need 2 thinks here, one is to trust the garbage collector, let's say by seeing benchmarks and proofs that it's realy working in Java, and know what I should never do in order to get my code the best way it can be. And the second think is knowing how to write other languages code. I mean I know what to do, I'm just never write the code as most Java or Python programmers usually do, are there any books for C++ programmers just to introduce me to the writing conventions? (by the way, forgive me for my English mistakes)

• Regular Expression

  - by equilibrium

  Ohh! this regular expression thing is eating my brain up. I have been reading it from Introduction to Automata Theory, Languages and Computer by Hopcroft, Motwani and Ullman. I have solved a few exercises too but could not solve the following even after trying for almost one hr. The problem is to write a regular expression that defines a language consisting of all strings of 0s and 1s except the substring 011. Is the answer (0+1)* - 011 correct ? If not what should be the correct answer for this?

• Is there a way to make this C# method shorter and more readable with the help of Linq?

  - by Hamish Grubijan

  The following works, but I figured - since it is all based on IEnumerable, Linq can come handy here is well. By the way, is there an equivalent to Directory.GetFiles() which would return an IEnumerable instead of the array? If it exists, then would it make the code run any faster? The last part of the question is inspired by Python language which favors lightweight generators over concrete lists. private IEnumerable<string> getFiles(string strDirectory, bool bCompressedOnly) { foreach (var strFile in Directory.GetFiles(strDirectory)) { // Don't add any existing Zip files since we don't want to delete previously compressed files. if (!bCompressedOnly || Path.GetExtension(strFile).ToLower().Equals(".zip")) { yield return strFile; } } foreach (var strDir in Directory.GetDirectories(strDirectory)) { foreach (var strFile in getFiles(strDir, bCompressedOnly)) { yield return strFile; } } }

• What's the deal with a leading underscore in PHP class methods?

  - by nocash

  While looking over various PHP libraries I've noticed that a lot of people choose to prefix some class methods with a single underscore, such as public function _foo() ...instead of... public function foo() I realize that ultimately this comes down to personal preference, but I was wondering if anyone had some insight into where this habit comes from. My thought is that it's probably being carried over from PHP 4, before class methods could be marked as protected or private, as a way of implying "do not call this method from outside the class". However, it also occurred to me that maybe it originates somewhere (a language) I'm not familiar with or that there may be good reasoning behind it that I would benefit from knowing. Any thoughts, insights and/or opinions would be appreciated.

• Why are configuration arrays acceptible parameters in PHP and Javascript?

  - by RenderIn

  In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

• Are `return` and `break` useless inside a Ruby block when used as a callback?

  - by Skilldrick

  In Rails, blocks can be used as callbacks, e.g.: class User < ActiveRecord::Base validates_presence_of :login, :email before_create {|user| user.name = user.login.capitalize if user.name.blank?} end When a block is used like this, is there any use for break and return? I'm asking because normally in a block, break will break out of the loop, and return will return from the enclosing method. But in a callback context, I can't get my head round what that means. The Ruby Programming Language suggests that return could cause a LocalJumpError but I haven't been able to reproduce this in a Rails callback. Edit: with the following code I'd expect a LocalJumpError, but all the return does is stop the rest of the callback executing. class User < ActiveRecord::Base validates_presence_of :login, :email before_create do |user| return user.name = user.login.capitalize end

• What is the best way to prevent a webpage coded completely in HTML (no PHP or any server side langua

  - by racl101

  I thought by placing these two lines that it would prevent the page from being cached but this is not the case between the head tags: <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> As already mentioned this is on server that doesn't support PHP (or any server side language, well, that's not true, it has cgi-bin folder that supports perl scripts but I don't know perl and have no time to engage in it.) What else could I do to prevent the page from caching? It caches on Firefox and IE (and not so much in Chrome or Safari.)

• How do I modify a string printed by a script?

  - by Liso22

  I'm having problems with wordpress mishandling accented characters, or maybe the problem is with some plugin. Whichever the case I need to "translate" some strings, removing accents which i do with: $value = strtr($value, $trans); I really need to change this string which renders the user's location but it's printed with a script so I have no idea how to do it: <script language="javascript"> document.write('' + geoip_city() +''); </script> Is there a way to assign it's result to a php value beforehand or something? Maybe removing the accents with a script. I really need to modify it, how could I manage to do it? Thanks

Appreciate all the help in advance. Thanks

• How can I create a menu in the start menu for my program?

  - by Joe

  This may be an easy question but I am not even sure of the terminology to search, so I have to ask. I want my program to have a menu when it is hovered over if it is pinned to the start menu. I am attaching a screenshot where windows powershell illustrates this function, and presents a list of tasks. Other programs sometimes use this to list recently opened files, etc. I am sure this is standard enough that there is a tutorial on it somewhere, would someone mind pointing me to it, or explaining how to do this? I hope that it doesn't matter too much what language is used, but I am proficient in Delphi, C++, and C#.

• JSONP parsing error from WCF

  - by user1754730

  Answered my own question I had a problem with a jquery (jsonp) call to a WCF service that was throwing a json parsing error. Using ASP.NET 4.0 on the WCF side and jquery 1.7 on the client side. Turned out there was an old set of script tags on the page using language = VBSCRIPT. The browser was interpreting the returned json packet of script as "VBscript" instead of javascript. I placed a set of empty javascript tags at the top of the page and the browser is now interpreting the json as the proper javascript function. Hope this helps someone else. Tom

• Const-Qualification of Main's Parameters in C++

  - by pt2cv

  The C++ standard mandates that all conforming implementations support the following two signatures for main: int main(); int main(int, char*[]); In case of the latter signature, would the addition of (top-level) const-ness break any language rules? For example: int main(const int argc, char** const argv); From my understanding, top-level const qualification doesn't affect the function's signature hash, so it should be legal as far as the specification is concerned. Also, did anyone ever encounter an implementation which rejected this type of modification?

• Need help with some C# Counting Code

  - by kaywai

  Hi, I'm trying to code a counter in Ninjatrader which uses C# as its programming language. I would like this counter to commence counting upon the completion of the first counter and once it commences counting to consider only the new condition when counting. So, the first counter commences when Close[0] < Close[4]. The second counter commences ONLY after the first counter has reached 9 and its condition for counting is Close[0] <= Low[2]. I don't know how to write the part of the code where the second counter commences counting and its counts are independent of the first counter reaching 9.

• How exactly can Python compliment your C# skills for windows based development?

  - by JL

  I'm looking for a fun challenge, and am thinking about learning Python. I've heard really good things about the language. My question is, how (if at all) can Python compliment the skills of a typical C# developer working mainly with MS technologies on a Windows Platform. Some examples of typical C# dev on windows would be (SOA applications, web applications, windows services, automation, xml handling) Surely there must be some scenarios where knowing Python would help you get certain tasks done quicker or more efficiently than using traditional C# / MS technologies. If you know of any specific scenarios, then please share. And lastly should this question be a community wiki?
