• git commit best practices

  - by Ivan Z. Siu

  I am using git to manage a C++ project. When I am working on the projects, I find it hard to organize the changes into commits when changing things that are related to many places. For example, I may change a class interface in a .h file, which will affect the corresponding .cpp file, and also other files using it. I am not sure whether it is reasonable to put all the stuff into one big commit. Intuitively, I think the commits should be modular, each one of them corresponds to a functional update/change, so that the collaborators could pick things accordingly. But seems that sometimes it is inevitable to include lots of files and changes to make a functional change actually work. Searching did not yield me any good suggestion or tips. Hence I wonder if anyone could give me some best practices when doing commits. Thanks! PS. I've been using git for a while and I know how to interactively add/rebase/split/amend/... What I am asking is the PHILOSOPHY part.

• Invoking a function (main()) from a binary file in C

  - by Dhara Darji

  I have simple c program like, my_bin.c: #include <stdio.h> int main() { printf("Success!\n"); return 0; } I compile it with gcc and got executable: my_bin. Now I want to invoke main (or run this my_bin) using another C program. That I did with mmap and function pointer like this: #include <stdio.h> #include <fcntl.h> #include <sys/mman.h> int main() { void (*fun)(); int fd; int *map; fd = open("./my_bin", O_RDONLY); map = mmap(0, 8378, PROT_READ, MAP_SHARED, fd, 0); fun = map; fun(); return 0; } PS: I went through some tutorial, for how to read binary file and execute. But this gives Seg fault, any help appreciated! Thanks!

• How to remove erroneous dependency from tycho build?

  - by sfinnie

  Context: Have built an eclipse update site using tycho but trying to install into target IDE fails. The update site builds fine; I can see it from a target eclipse installation and select the feature for installation. However, the dependency check fails at start of install as it can't find a declared dependency (org.eclipselabs.xtext.utils.unittesting). This shouldn't be a dependency: it was erroneously included in MANIFEST.MF for one of my eclipse plugin projects. I removed the dependency from the manifest and run mvn clean install. Build reported success. However when I try to use the newly built update site it still complains that the dependency to org.eclipselabs.xtext.utils.unittesting (a) exists and (b) can't be satisfied. So the question is: what else do I need to do to remove the dependency from the generated update site? Thanks for any pointers. PS: I know I could add the site for o.e.x.u.unittesting in the target eclipse installation so it can satisfy the dependency. However I don't want to do that; it's not needed for the feature to work and I don't want other users to have to add an unnecessary dependency.

• what is a root directory in IIS 6 and How do I make one of my subfolder in ASP.NET website the root directory?

  - by R_Coder

  I need to integrate a third party plugin in my asp.net website. To install the plugin, they have mentioned this sentence, "Create an application through your IIS control panel with root directory at -(some path from my website folder)?". I am not much aware with IIS and rarely worked with it. Though I tried every possible way i could do in IIS, I am not able to work it out. After installation, there is a test page provided by plugin which i have to run to check but when I run it, it shows this error. "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS." I searched this error too and found that it is because the two Web.Config file, one from the main project and another from plugin folder. The only way to work with this is to make the plugin folder they specified as root directory in IIS. Someone kindly tell me some easy steps to do this. What I was doing is, in IIS6, I added New website with the main folder of my asp.net website, then I right clickadd application and choosed the gievn path, thought it would become root directory but it ain't. Help would be appreciated. ALso note that, i have to put the plugin folder in my main website folder only. So, there are two web.config. I tried to rename one of them too, it solved the above error but gave another errors but I think main problem is of root directory. P.S they show me above error on web.config file of plugin folder on this sentence- "Line 51: < authentication mode="Windows" />"

• How To Call Javascript In Ajax Response? IE: Close a form div upon success...

  - by B.Gordon

  I have a form that when you submit it, it sends the data for validation to another php script via ajax. Validation errors are echo'd back in a div in my form. A success message also is returned if validation passes. The problem is that the form is still displayed after submit and successful validation. I want to hid the div after success. So, I wrote this simple CSS method which works fine when called from the page the form is displayed on. The problem is that I cannot seem to call the hide script via returned code. I can return html like echo "<p>Thanks, your form passed validation and is being sent</p>"; So I assumed I could simply echo another line after that echo "window.onload=displayDiv()"; inside script tags (which I cannot get to display here)... and that it would hide the form div. It does not work. I am assuming that the problem is that the javascript is being returned incorrectly and not being interpreted by the browser... How can I invoke my 'hide' script on the page via returned data from my validation script? I can echo back text but the script call is ineffective. Thanks! This is the script on the page with the form... I can call it to show/hide with something like onclick="displayDiv()" while on the form but I don't want the user to invoke this... it has be called as the result of a successful validation when I write the results back to the div... function displayDiv() { var divstyle = new String(); divstyle = document.getElementById("myForm").style.display; if(divstyle.toLowerCase()=="block" || divstyle == "") { document.getElementById("myForm").style.display = "none"; } else { document.getElementById("myForm").style.display = "block"; } } PS: I am using the mootools.js library for the form validation if this matters for the syntax..

• How to change the meaning of pointer access operator

  - by kumar_m_kiran

  Hi All, This may be very obvious question, pardon me if so. I have below code snippet out of my project, #include <stdio.h> class X { public: int i; X() : i(0) {}; }; int main(int argc,char *arv[]) { X *ptr = new X[10]; unsigned index = 5; cout<<ptr[index].i<<endl; return 0; } Question Can I change the meaning of the ptr[index] ? Because I need to return the value of ptr[a[index]] where a is an array for subindexing. I do not want to modify existing source code. Any new function added which can change the behavior is needed. Since the access to index operator is in too many places (536 to be precise) in my code, and has complex formulas inside the index subscript operator, I am not inclined to change the code in many locations. PS : 1. I tried operator overload and came to conclusion that it is not possible. 2. Also p[i] will be transformed into *(p+i). I cannot redefine the basic operator '+'. So just want to reconfirm my understanding and if there are any possible short-cuts to achieve. Else I need fix it by royal method of changing every line of code :) .

• MS Excel automation without macros in the generated reports. Any thoughts?

  - by ezeki77

  Hello! I know that the web is full of questions like this one, but I still haven't been able to apply the answers I can find to my situation. I realize there is VBA, but I always disliked having the program/macro living inside the Excel file, with the resulting bloat, security warnings, etc. I'm thinking along the lines of a VBScript that works on a set of Excel files while leaving them macro-free. Now, I've been able to "paint the first column blue" for all files in a directory following this approach, but I need to do more complex operations (charts, pivot tables, etc.), which would be much harder (impossible?) with VBScript than with VBA. For this specific example knowing how to remove all macros from all files after processing would be enough, but all suggestions are welcome. Any good references? Any advice on how to best approach external batch processing of Excel files will be appreciated. Thanks! PS: I eagerly tried Mark Hammond's great PyWin32 package, but the lack of documentation and interpreter feedback discouraged me.

• overwrite parameters passed by querystring

  - by opensas

  I have the following problem I have a web framework built with classic asp that saves the page state in hidden textboxes, and then issues a submit to itself. Before submitting, we have a javascript functions that saves the action in a hidden "action" input, and then performs the submit. The page loads the state from those hidden texts, reads the action issued, reads extra parameters, like the id of the record to edit, and then builds the page accordingly. I'd like to make a url link to automatically start the page with "edit" action on a "x" id. So I was thinking about building the following url, for example http://myapp/user?action=edit&id=23 the problem is that when the page auto-submits, que url string keeps the parameters. I'd like to achieve the following: when the user clicks on http://myapp/user?action=edit&id=23 my page should receive the posted values action=edit and id=23 but the url should be just http://myapp/user and both parameters should be kept in the hidden texts... (I wonder if I make myself clear...) thanks a lot saludos sas ps: I have a couple of ideas about how to solve it, but I'll post them as answers...

• Good ways to earn income as a self employed developer

  - by nullptr

  I was just wondering if people could share their experiences and ideas about generating / earning income from a software product or service they have personally developed. To me this seems like a good way to earn a living while doing what we love (programming) and working on projects and problems which interest us. Ie, NOT boring bank or marketing software etc 9-5 all week... Some ideas I have are things like web 2.0 style sites (Facebook,Youtube,Twitter,Digg) etc etc... - These can be very very profitable as we all know but can take years to take off. Are there ways to survive until/if this does happen? Mobile applications. Iphone, Google Android and the new up coming Nintendo DS app store. These have good potential to make it easy to find a market for your application and make selling it easy. Shareware/PC software. A bit 80's and 90's and you kind of need to be a salesman/marketer to sell it but its the only other thing I can think of. Also im not talking about doing freelance work. Im only interested in idea's you can come up with and develop your self (not other peoples ideas or problems which are you are payed to develop). Things that a sole developer or at the most 2 developers could work on and have good potential for high returns on investment (in terms of time) would be great. PS, I wish I thought of stackoverflow!

• Sorting XML file through multiple attributes

  - by jbugeja

  I want to sort a 'free-form' XML file through multiple attributes (first by T and then by L). The XML is a bit complex and it is structured as shown below: <?xml version="1.0" encoding="utf-8"?> <wb xmlns:cf="http://www.macromedia.com/2004/cfform" xmlns:a="urn:dummy"> <a:form name="chart"> <a:fieldset FIELD="a" FIELDNAME="FieldSet1"> <a:select1 FIELDNUMBER="01" L="1" T="2" /> <a:input FIELDNUMBER="02" INDEX="4" L="200" T="1" /> </a:fieldset> <a:fieldset FIELD="b" FIELDNAME="FieldSet1"> <a:select1 FIELDNUMBER="03" T="3" L="1" /> <a:input FIELDNUMBER="04" INDEX="7" T="4" L="200" /> <a:fieldset FIELD="c" FIELDNAME="FieldSet1"> <a:input FIELDNUMBER="05" T="10" INDEX="6" L="400" /> <a:input FIELDNUMBER="06" T="8" INDEX="8" L="200" /> </a:fieldset> </a:fieldset> <a:input FIELDNUMBER="08" INDEX="3" L="3" T="5" /> <a:input FIELDNUMBER="09" INDEX="2" L="2" T="4" /> </a:form> </wb> PS: The root element is wb and this is always followed by a:form The L and T are always found in elements that have a tag in the namespace a, the only exception being a:fieldset which does not have L and T a:fieldset could have multiple children of the namespace a including another a:fieldset We can also assume that L denotes Left and T denotes Top. So, the idea of this is that when I view the transformed XML I can immediately note which elements precede what. What's your take on this?

• Why jquery have problem with onbeforeprint event?

  - by Cesar Lopez

  Hi all, I have the following function. $(function() { $(".sectionHeader:gt(0)").click(function() { $(this).next(".fieldset").slideToggle("fast"); }); $("img[alt='minimize']").click(function(e) { $(this).closest("table").next(".fieldset").slideUp("fast"); e.stopPropagation(); return false; }); $("img[alt='maximize']").click(function(e) { $(this).closest("table").next(".fieldset").slideDown("fast"); e.stopPropagation(); return false; }); }); <script type="text/javascript"> window.onbeforeprint = expandAll; function expandAll(){ $(".fieldset:gt(0)").slideDown("fast"); } </script> For this html <table class="sectionHeader" ><tr ><td>Heading 1</td></tr></table> <div style="display:none;" class="fieldset">Content 1</div> <table class="sectionHeader" ><tr ><td>Heading 2</td></tr></table> <div style="display:none;" class="fieldset">Content 2</div> I have several div class="fieldset" over the page, but when I do print preview or print, I can see all divs sliding down before opening the print preview or printing but on the actual print preview or print out they are all collapse. I would appreciate if anyone comes with a solution for this. Anyone have any idea why is this or how to fix it? Thanks. PS:Using a does not work either ( I assume because jquery using toggle) and its not the kind of question I am looking for.

• Adjust width of td to make make row widths even

  - by user1729886

  I am trying to produce a table with a different number of cells in each row. The first row is a header row (every other row contains cells). This header is the width of the table. The second row has 2 cells in it... the third has 1 cell... the fourth has 4 cells... the fifth and final row has 3 cells. I want the table set up so that the rows span the full width of the table. If the table is 1000px... The header would be 1000px wide the cells in the 2nd row would be 500px EACH the cell in the 3rd row would be 1000px the cells in the 4th row would be 250px EACH and the cells in the 5th row would be 333px, 334px, and 333px each (left-to-right) I figured out I could use colspan for the first 4 rows, but the 5th (with 3 cells) would require a non-integer value. The cells in the 5th row won't expand beyond their column without colspan that I can tell... trying the width:## CSS code inside a div tag for each cell inside the td tag creating a class or classes that define the cell widths id-ing each cell, with or without a div tag, and defining widths individually and adjuting the table-layout: option After several days, I'm now at my rope's end. The only thing I can come up with is deliberately tripling the number of cells in each row so that colspan would be all integer values. That sounds inconvenient and unreasonably difficult to format the table the way I'd like. It's a table of Batman movies for a website -- a practice website I'm building, in order to learn HTML/CSS. I've been working on-and-off with HTML for several months, and CSS for a few weeks. PS: It is not being used for layout, I am simply trying to adjust the layout of the table itself.

• Pushing a vector into an vector

  - by Sunil

  I have a 2d vector typedef vector <double> record_t; typedef vector <record_t> data_t; data_t data; So my 2d vector is data here. It has elements like say, 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 5 5 5 5 5 Now I want to insert these elements into another 2d vector std::vector< vector<double> > window; So what I did was to create an iterator for traversing through the rows of data and pushing it into window like std::vector< std::vector<double> >::iterator data_it; for (data_it = data.begin() ; data_it != data.end() ; ++data_it){ window.push_back ( *data_it ); // Do something else } Can anybody tell me where I'm wrong or suggest a way to do this ? BTW I want to push it just element by element because I want to be able to do something else inside the loop too. i.e. I want to check for a condition and increment the value of the iterator inside. for example, if a condition satisfies then I'll do data_it+=3 or something like that inside the loop. Thanks P.S. I asked this question last night and didn't get any response and that's why I'm posting it again.

• Makefile; mirroring a growing tree through a process

  - by Martineau

  I would like to periodically mirror a growing tree, say, from $in to $out, doing a process in between (saving the only file header). As; #!/bin/bash in=./segd out=./db for f in `find $in -name "*.segd"`;do # Deduct output (dir + name) d=`dirname $f|perl -pe 's!'$in'!'$out'!'` n=`basename $f|perl -pe 's!$!_hdr!'` if [ ! -e $d/$n ]; then [ ! -d $d ] && mkdir -p $d; printf "From %s now build %s\n" $f "$d/$n" # Do something, whathever. For example e.g; dd if=$f bs=32 count=1 conv=swab 2>/dev/null|od -x > $d/$n fi done That is about fair. However; to be more robust, for a better synchronization (say if a source file did change or whatever), I would like to use a Makefile, as in; HDR := $(patsubst ./segd/%.segd,./db/%.segd_hdr,$(wildcard ./segd/*.segd)) all: ${HDR} db/%.segd_hdr: ./segd/%.segd echo "Doing" dd if=$< bs=32 count=1 conv=swab 2>/dev/null|od -x > $@ My problem; I cannot code this Makefile to "dive" more deeply within the source ./segd tree. How can we do it and is there a way ? Many thanks for your kind recommendations. PS: The idea will be to later rsync the (smaller) destination tree over a sat connection.

• Border of single th spreads to neighboring th when colspan set on td row below

  - by Samuel Hapak

  Having following html code: <table> <tr><th>First</th><th class='second'>Second</th><th class='third'>Third</th><th>Fourth</th></tr> <tr><td>Mike</td><td colspan=2 >John</td><td>Paul</td></tr> </table>? And following css: table { border-collapse: collapse; } td, th { border: 1px black solid; } td { border-top: none; } th { border-bottom: none; } th.second { border-bottom: 3px green solid; } th.third { } ? I would expect as result one table with 3px solid green line below the second th cell. Instead of that in Chrome, I have solid green border below both the second and the third th cell. In the firefox, results are just as expected. Is this browser bug, or my code is illegal? You can see example at http://jsfiddle.net/tt6aP/3/ PS: Try to set th.third { border-bottom: 2px solid red; } And then try to raise it to 3px. This is even more strange.

• association of more than one model to a listview

  - by Veer

  I have 3 Tables in my database. Each table has 3 fields each, excluding the ID field. out of which 2 fields are of type nvarchar. None of the tables are related. My ListView in the application helps the user to search my database, the search being incremental. The search includes the nvarchar fields of the 3 tables ie, 6 fields in total. Eg: PhoneBook: Name, PhoneNo Notes: Title, Content Bookmarks: Name, url I've the models generated for the 3 tables. Now the ListBox should display the Ph.Name, Title and the Bo.Name fields. ie, It should be bound to them. But they are from different models. I also should be able to perform CRUD operation on the item searched. How would i do that? P.S: Separate ViewModels are created for each Model which are used for their respective views for handling those tables individually. But this is an integrated view where the user should be able to search everything. Also please somebody suggest me a better Title for this question:)

• Why does PEAR get installed to my user directory?

  - by webworm

  I am new to Linux and I am attempting to install the PHP PEAR library on a virtual server which is running Ubuntu. I am following a tutorial that covers installing PEAR but have run up against an area where I am confused. When running the PEAR installation program I am prompted as to what I want the INSTALL_PREFIX to be. Evidently the INSTALL_PREFIX, among other things, determines where PEAR will be installed. The tutorial suggest the value of INSTALL_PREFIX be the following path ... "/home/MY_USER_NAME/pear" where MY_USER_NAME = my user account Having come from a Windows world, applications are installed on the system where everyone can use them. If I install PEAR underneath my user directory will other developers on the system be able to make use of PEAR in their PHP scripts? I want to make PEAR available to all users and not just myself. Could someone explain to me the difference between installing for all users and installing just for myself? Does the install location matter? Should I be installing PEAR in a different location? Thanks for any suggestions. P.S. The tutorial I am following is located at the following URL ... http://articles.sitepoint.com/article/getting-started-with-pear/2

• Android ListView: how to select an item?

  - by mmo

  I am having trouble with a ListView I created: I want an item to get selected when I click on it. My code for this looks like: protected void onResume() { ... ListView lv = getListView(); lv.setOnItemSelectedListener(new OnItemSelectedListener() { public void onItemSelected(AdapterView<?> adapterView, View view, int pos, long id) { Log.v(TAG, "onItemSelected(..., " + pos + ",...) => selected: " + getSelectedItemPosition()); } public void onNothingSelected(AdapterView<?> adapterView) { Log.v(TAG, "onNothingSelected(...) => selected: " + getSelectedItemPosition()); } }); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> adapterView, View view, int pos, long id) { lv.setSelection(pos); Log.v(TAG, "onItemClick(..., " + pos + ",...) => selected: " + getSelectedItemPosition()); } }); ... } When I run this and click e.g. on the second item (i.e. pos=1) I get: 04-03 23:08:36.994: V/DisplayLists(663): onItemClick(..., 1,...) => selected: -1 i.e. even though the OnItemClickListener is called with the proper argument and calls a setSelection(1), there is no item selected (and hence also OnItemSelectedListener.onItemSelected(...) is never called) and getSelectedItemPosition() still yields -1 after the setSelection(1)-call. What am I missing? Michael PS.: My list does have =2 elements...

• how to get selected chracter position in JTextArea?

  - by Reddy

  Hi! Here is a challenging question! Let me first tell you my scenario how am i implementing a solution to a problem. I am reading a log file and displaying it on the JTextArea. Log file is cp037 character coded. I was reading each file as a byte stream or byte array from the log file & displaying it. Anyways, i managed to display the text properly in JTextArea by cp037 character coding. Now, User may select a set of characters in the JTextArea. All i want is the position of first character of the user's selected text, from a nearest special character '+'(its character code in cp037 is 4E), which is prior to the selected text. This character may occur at several places in the JTextArea. In simple sentence, i want the first character location(of user selected text) from nearset '+' which should be occuring prior to the user's selected text. PS: cp037 is a type of character encoding scheme which is created by IBM & used for IBM Mainframes. Please fell free to ask me if the question is not clear...:-

• Alternative for table mark-up in ASP.NET not working properly

  - by yetanothercoder

  Using Visual WebDeveloper 2010 Express and ASP.NET 4.0 Don't know whether its relevant but the whole thing is in a ContentPlaceHolder and inside an UpdatePanel. To avoid using the old table tr td model, I have created a simple form like this <div class="admin-form"> <asp:Label ID="UserNameLabel" runat="server" CssClass="form-label" Text="User Name" /> <asp:TextBox ID="UserNameText" runat="server" Width="200px"/> <br /> <asp:Label ID="PasswordLabel" runat="server" CssClass="form-label" Text="Password" /> <asp:TextBox ID="PasswordText" runat="server" TextMode="Password" Width="200px"/> <br /> <asp:Label ID="ConfirmPasswordLabel" runat="server" CssClass="form-label" Text="Confirm Password" /> <asp:TextBox ID="ConfirmPasswordText" runat="server" TextMode="Password" Width="200px"/> <br /> <asp:Label ID="EmailLabel" runat="server" CssClass="form-label" Text="Email" /> <asp:TextBox ID="EmailText" runat="server" Width="200px"/> <br /> <br /> <br /> <span class="form-label"></span> <asp:Button ID="CreateUserButton" runat="server" CssClass="button blue" Text="Create New User"/> </div> And the CSS .form-label { width: 300px !important; } This renders incorrectly as I would like to have all textboxes vertically lined after taking 300px. What is wrong? P.S: I cannot use HTML Controls like label as I have resx for globalization

• How to use Enquire.Js?

  - by big_smile

  Enquire.js is a Javascipt that re-creates CSS media queries for Javascripts. This means you can wrap your Javascripts in Media Queries. (Just like you would wrap CSS in Media Queries). I'm not quite sure how to use it. This tutorial says this: enquire.register("max-width: 960px", function() { // put your code here }); However, when I follow that, my code stops working. Here is an example of some Jquery Tabs without Enquire.JS. It works fine. Here are the same tabs, but with Enquire.JS added. Now it stops working. I've experimented with different variations of the code, but none of them work. What am I doing wrong? I think you might have place the Jquery Tab code in a separate file and then link to that file from within Enquire.Js, but I'm not sure how you would do that. (Although it would be handy to know as I'd imagine it would let you keep your scripts be more reusable). PS. This is not a criticism of Enquire.Js. I know that the problem lies squarely with my lack of proficiency in Javascript! I did spend a couple of hours searching for a solution, but couldn't find anything. Thanks for any help!

• How to mark multiple coordinates in KML using Java?

  - by Akshay

  I'm working on a project that involves KML creation using Java. Currently, I'm fooling with the sample Java code from the KML example at Micromata Labs JAK Example. I tried to "extend" the code by adding multiple coordinates and getting two markers, but I could not get it to work. Can you please tell me how I can add multiple coordinates and put markers on them, and also, draw a line between the markers. Thank you for your help! PS: I need to do this via the program. I saw sample code of them using DOM and XML, but not pure Java/JAK as such. Please guide me. I got as far as this: kml .createAndSetDocument().withName("My Markers"). createAndAddPlacemark().withName("London, UK").withOpen(Boolean.TRUE) .createAndSetPoint().addToCoordinates(-0.126236, 51.500152); kml.createAndSetPlacemark() .withName("Somewhere near London, UK").withOpen(Boolean.TRUE) .createAndSetPoint().addToCoordinates(-0.129800,52.700152); But I know I'm going wrong somewhere. Please point me in the right direction.
