• Compilation of latex file

  - by Tim

  Hi, I am compiling a latex file on a server and download from there the generated dvi, ps and pdf files to view them. The latex file by \includegraphics includes some figure files which are not on my local machine. I found that dvi file generated by latex command does not show the figures after dowloaded to my local, but ps file generated by dvips -Ppdf have the figures, and pdf file generated by either ps2pdf or pdflatex seem not have the figures again. Is it because the figures are not actually embeded as part of the dvi and pdf files by those compilation commands? How to actually embed figures so we can only export the document files to other machines? are the case for tables in separated tex files included into main tex file by /input and the case for style files included by \usepackage similar to the above case for figure files included by \includegraphics ? Thanks and regards!

• phpbb template comment conditional

  - by john

  I see in PHPBB they use conditional statements inside their html, or xhtml, if you dont know what I mean here is a snippet: <!-- IF MODERATORS --> <p class="moderators"><!-- IF S_SINGLE_MODERATOR -->{L_MODERATOR}<!-- ELSE -->{L_MODERATORS}<!-- ENDIF -->: {MODERATORS}</p> <!-- ENDIF --> <!-- IF U_MCP --> <p class="linkmcp">[ <a href="{U_MCP}">{L_MCP}</a> ]</p> <!-- ENDIF --> Is there an explanation on how to implement this in my own site, as it would be very useful and clean up a lot of code.

• Java: conditional initialization?

  Ruby has conditional initialization. Apparently, Java does not or does it?

• Recursive compilation using gcc

  - by curiousexplorer

  I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories and their subdirectories and so on... This command should be invoked from the home directory of the code project.

• Compilation hangs for a class with field double d = 2.2250738585072012e-308

  - by 01es

  I have come across an interesting situation. A coworker committed some changes, which would not compile on my machine neither from the IDE (Eclipse) nor from a command line (Maven). The problem manifested in the compilation process taking 100% CPU and only killing the process would help to stop it. After some analysis the cause of the problem was located and resolved. It turned out be a line "double d = 2.2250738585072012e-308" (without semicolon at the end) in one of the interfaces. The following snipped duplicates it. public class WeirdCompilationIssue { double d = 2.2250738585072012e-308 } Why would compiler hang? A language edge case?

• mysql conditional query - complicated!

  - by emre

  i want to get distinct values for a field, let say: field1... ok this needs a query like: "select distint(field1) from table" however for some records, field1 is empty and there is another column that is an alternative to field1, which is field2. now; for the records where field1 is empty i need to use the value of field2. i think i need sort of a conditional select statement with if control something like: "select distinct( (if(field1!='') field1 else field2) ) from table" but i have no idea on how to write it. any help is appricated...

• Basic Python While loop compound conditional evaluation

  - by dbjohn

  In Python IDLE Shell it seems I cannot use a compound conditional expression and a while loop. I tried it within brackets too. k=0 m=0 while k<10 & m<10: print k k +=1 m+=1 If I write while k<10: print k k+=1 This does work. Is there a way I could achieve the first block of code with the "and" operator. I have done it in Java. Do I just need to put together "if" statements to achieve the same functionality in Python?

• HTML / Conditional Comments - Do conditional comments behave as expected across browsers?

  Do conditional comments behave as expected across browsers? Can they cause rendering bugs or other issues?

How else can do way conditional? In rich client I used pattern Visitor. // my bad english, I know =(

• Process results of conditional split in SSIS

  - by Robert

  I have a Data Flow Task and am connecting to a database via an OLE DB Source component to extract data. This data feeds into a Conditional Split component to separate the data based on a simple expression. After the evaluation of this expression, the data will end up in either of two locations: LocationA or LocationB. Alright, I have that all set up and working properly. Once the data is separated into these two locations, additional processing is to be done on the records. Here's where I am stuck: I need the the processing of records in LocationA to occur before the processing of records in LocationB. Is there a way to set precedence of which tasks occur before others? If not, what is the best way to handle this? I was thinking I may need to write the data in LocationA and LocationB back out to the database and create a new data flow task in the control flow to handle the order of which these records must be dealt with. Any help is greatly appreciated!

• Error when changing default lanuage in asp.net compilation from vb to c#

  - by Herman

  Hi all, We have a updatable web site project that is written in c#, it has the usual web form implementation using master page, skins, user controls,...etc. Up to this point we neglect to change the default compilation language from VB to C#. However, the second we change it, we see the following error. Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ASP.Default.__DataBinding__control499(Object sender, EventArgs e) at System.Web.UI.Control.OnDataBinding(EventArgs e) at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at .... Further investigation points out that this error is getting generated from a Theme related assembly (Source : App_Theme_Default.zclakrlo). Any ideas? One of my co-worker suggested that it might be skin file related since we have a theme call "Default" and there is no way to specify a language on a skin file. Therefore, when the asp.net runtime tries to compile it under C#, it will give a name collision? Does this make sense? Any help is appreciated.

• Conditional operator in Mako using Pylons

  - by Antoine Leclair

  In PHP, I often use the conditional operator to add an attribute to an html element if it applies to the element in question. For example: <select name="blah"> <option value="1"<?= $blah == 1 ? ' selected="selected"' : '' ?>> One </option> <option value="2"<?= $blah == 2 ? ' selected="selected"' : '' ?>> Two </option> </select> I'm starting a project with Pylons using Mako for the templating. How can I achieve something similar? Right now, I see two possibilities that are not ideal. Solution 1: <select name="blah"> % if blah == 1: <option value="1" selected="selected">One</option> % else: <option value="1">One</option> % endif % if blah == 2: <option value="2" selected="selected">Two</option> % else: <option value="2">Two</option> % endif </select> Solution 2: <select name="blah"> <option value="1" % if blah == 1: selected="selected" % endif >One</option> <option value="2" % if blah == 2: selected="selected" % endif >Two</option> </select> In this particular case, the value is equal to the variable tested (value="1" = blah == 1), but I use the same pattern in other situations, like <?= isset($variable) ? ' value="$variable" : '' ?>. I am looking for a clean way to achieve this using Mako.

• Most readable way to write simple conditional check

  - by JRL

  What would be the most readable/best way to write a multiple conditional check such as shown below? Two possibilities that I could think of (this is Java but the language really doesn't matter here): Option 1: boolean c1 = passwordField.getPassword().length > 0; boolean c2 = !stationIDTextField.getText().trim().isEmpty(); boolean c3 = !userNameTextField.getText().trim().isEmpty(); if (c1 && c2 && c3) { okButton.setEnabled(true); } Option 2: if (passwordField.getPassword().length > 0 && !stationIDTextField.getText().trim().isEmpty() && !userNameTextField.getText().trim().isEmpty() { okButton.setEnabled(true); } What I don't like about option 2 is that the line wraps and then indentation becomes a pain. What I don't like about option 1 is that it creates variables for nothing and requires looking at two places. So what do you think? Any other options?

• Replace conditional with polymorphism refactoring or similar?

  - by Anders Svensson

  Hi, I have tried to ask a variant of this question before. I got some helpful answers, but still nothing that felt quite right to me. It seems to me this shouldn't really be that hard a nut to crack, but I'm not able to find an elegant simple solution. (Here's my previous post, but please try to look at the problem stated here as procedural code first so as not to be influenced by the earlier explanation which seemed to lead to very complicated solutions: http://stackoverflow.com/questions/2772858/design-pattern-for-cost-calculator-app ) Basically, the problem is to create a calculator for hours needed for projects that can contain a number of services. In this case "writing" and "analysis". The hours are calculated differently for the different services: writing is calculated by multiplying a "per product" hour rate with the number of products, and the more products are included in the project, the lower the hour rate is, but the total number of hours is accumulated progressively (i.e. for a medium-sized project you take both the small range pricing and then add the medium range pricing up to the number of actual products). Whereas for analysis it's much simpler, it is just a bulk rate for each size range. How would you be able to refactor this into an elegant and preferably simple object-oriented version (please note that I would never write it like this in a purely procedural manner, this is just to show the problem in another way succinctly). I have been thinking in terms of factory, strategy and decorator patterns, but can't get any to work well. (I read Head First Design Patterns a while back, and both the decorator and factory patterns described have some similarities to this problem, but I have trouble seeing them as good solutions as stated there. The decorator example seems very complicated for just adding condiments, but maybe it could work better here, I don't know. And the factory pattern example with the pizza factory...well it just seems to create such a ridiculous explosion of classes, at least in their example. I have found good use for factory patterns before, but I can't see how I could use it here without getting a really complicated set of classes) The main goal would be to only have to change in one place (loose coupling etc) if I were to add a new parameter (say another size, like XSMALL, and/or another service, like "Administration"). Here's the procedural code example: public class Conditional { private int _numberOfManuals; private string _serviceType; private const int SMALL = 2; private const int MEDIUM = 8; public int GetHours() { if (_numberOfManuals <= SMALL) { if (_serviceType == "writing") return 30 * _numberOfManuals; if (_serviceType == "analysis") return 10; } else if (_numberOfManuals <= MEDIUM) { if (_serviceType == "writing") return (SMALL * 30) + (20 * _numberOfManuals - SMALL); if (_serviceType == "analysis") return 20; } else //i.e. LARGE { if (_serviceType == "writing") return (SMALL * 30) + (20 * (MEDIUM - SMALL)) + (10 * _numberOfManuals - MEDIUM); if (_serviceType == "analysis") return 30; } return 0; //Just a default fallback for this contrived example } } All replies are appreciated! I hope someone has a really elegant solution to this problem that I actually thought from the beginning would be really simple... Regards, Anders

• How to Highlight a Row in Excel Using Conditional Formatting

  - by Erez Zukerman

  Conditional formatting is an Excel feature you can use when you want to format cells based on their content. For example, you can have a cell turn red when it contains a number lower than 100. But how do you highlight an entire row? If you’ve never used Conditional Formatting before, you might want to look at Using Conditional Cell Formatting in Excel 2007. It’s one version back, but the interface really hasn’t changed much. But what if you wanted to highlight other cells based on a cell’s value? The screenshot above shows some codenames used for Ubuntu distributions. One of these is made up; when I entered “No” in the “Really” column, the entire row got different background and font colors.

• Conditional Markup in aspx

  - by Dynde

  Hi... I have a ListView. If I want to base the html markup on a condition in respects to the databound item, what would be the best way to do that? What I mean is, is there any other way then putting <% % if/else blocks directly in the markup? I'm aware that a really ugly way of doing it, is putting html markup in the database field, and just let the Eval() squeeze out the proper markup (I'm not doing that). I would like to avoid putting actual <% % C# blocks in the code as well. Any good ideas?

• Jquery cookie plugin - conditional content determined by cookie being set

  - by Dave

  Hello I have a sign up form that is displayed to all new site visitors. If a user fills out the form, the next time they visit the site, I would like to display a "welcome back" message where the form would usually sit. I am trying to do this via the jquery cookie plugin (http://plugins.jquery.com/project/Cookie). My form would look like this: <div id="sign_up_form_wrapper"><form id="sign_up" action="" method="POST" name="form"> <input type="checkbox" name="checkbox" id="checkbox" value="1">&nbsp; I accept the terms and conditions</a> <br /><br /><input type="submit" value="ENTER"> </form></div> And I am setting my cookie here: <script type="text/javascript" language="javascript"> $().ready(function() { $('#sign_upm').submit(function(e) { e.preventDefault(); if ($('#sign_up input[name=checkbox]').is(':checked')) { $.cookie('agreed_to_terms', '1', { path: '/', expires: 999999 }); } }); }); </script> That will set the cookie when a user has checked the box, but now I need to do somehting like this: if the cookie has been set, do this: <div id="sign_up_form_wrapper"> <p>Welcome back, John</p> </div> otherwise do this: <div id="sign_up_form_wrapper"> <!-- full form code here --> </div> Any ideas or pointers would be very appreciated, thanks.

• Flex, Ant, mxmlc and conditional compilation

  - by Rezmason

  My ActionScript project builds with several compile-time specified constants. They are all Booleans, and only one of them is true at any given time. The rest must be false. When I represented my build process in a bash script, I could loop through the names of all these constants, set one of them to be true and the rest to be false, then concatenate them onto a string to be inserted as a set of arguments passed to mxmlc. In Ant, looping is more complicated. I've tried the ant-contrib for tag: <mxmlc file='blah' output='blah'> <!- ... -> <for list='${commaSeparatedListOfConstNames}' param='constName'> <sequential> <define> <name>${constName}</name> <value>${constName} == ${theTrueConst}</value> <!-- (mxmlc's define arguments can be strings that are evaluated at compile time) --> </define> </sequential> </for> </mxmlc> Long story short, ant-contrib tags like the for tag can't go in the mxmlc task. So now I'm using Ant's propertyregex to take my list of arguments and format them into a set of define args, like my old bash script: <propertyregex property='defLine.first' override='false' input='${commaSeparatedListOfConstNames}' regexp='([^\|]+)\,' replace='\1,false ' /> <propertyregex property='defLine.final' input='${defLine.first}' regexp='(@{theTrueConst}\,)false' replace='\1true' /> <!-- result: -define+=CONST_ONE,false -define+=CONST_TWO,false -define+=TRUE_CONST,true --> Now my problem is, what can I do with this mxmlc argument and the mxmlc task? Apparently arg tags can go inside the mxmlc task without it throwing an error, but they don't seem to have any effect. What am I supposed to do? How do I make this work with the mxmlc task?

• ActiveReports Conditional Formatting - Picture Visibility

  - by Joe

  In ActiveReports, how can I change formatting based on values in the report data? Specifically, I want to show or hide pictures based on a value in the data. The report gets bound to a list of objects via a set to its DataSource property. These objects have a Condition property with values "Poor", "Normal", etc. I have some pictures in the report that correspond to the different conditions, and I want to hide all the pictures except for the one corresponding to the value. Should I subscribe to the Format event for the detail section? If so, how do I get to the "current record" data?

• C# Conditional Operator Not a Statement?

  - by abelenky

  I have a simple little code fragment that is frustrating me: HashSet<long> groupUIDs = new HashSet<long>(); groupUIDs.Add(uid)? unique++ : dupes++; At compile time, it generates the error: Only assignment, call, increment, decrement, and new object expressions can be used as a statement HashSet.Add is documented to return a bool, so the ternary (?) operator should work, and this looks like a completely legitimate way to track the number of unique and duplicate items I add to a hash-set. When I reformat it as a if-then-else, it works fine. Can anyone explain the error, and if there is a way to do this as a simple ternary operator?
