• rails code within javascript

  - by Jesse

  I am trying to use some rails code withing a javascript and need to have that rails code be dynamically changed. Here's the line of code: $(this).replaceWith("<%= escape_javascript(render(:partial => 'shared/products')) %>"); The 'shared/products' is the part I want to change based off information passed earlier in the javascript. How do I insert a value from javascript so that instead of 'shared/products' the products portion can be a variable? Hope this makes sense. I'm not the most experienced jQuery/javascript programmer, so any help is very much appreciated. Thanks in advance!

• Writing a C Macro

  - by shaharg

  Hi, I have to write a macro that get as parameter some variable, and for each two sequential bits with "1" value replace it with 0 bit. For example: 10110100 will become 10000100. And, 11110000-00000000 11100000-100000000 I'm having a troubles writing that macro. I've tried to write a macro that get wach bit and replace it if the next bit is the same (and they both 1), but it works only for 8 bits and it's very not friendly... P.S. I need a macro because I'm learning C and this is an exercise i found and i couldn't solve it myself. i know i can use function to make it easily... but i want to know how to do it with macros. Thanks!

• VB.NET For Each steps into loop body for an IEnumerable collection! How? Why?

  - by Paul Sasik

  This is weird. I have a class that inherits from IEnumrable whose Count property is reporting 0 (zero) elements but the For Each loop steps into the loop body and tries to use the variable where it should just be moving on. My code: On Error Resume Next Dim d As Foo For Each d In fooCollection ' use d and throws an exception Next d Weirder still, every time d is accessed i get an exception thrown in the output window: A first chance exception of type 'System.NullReferenceException' but i'm not stopping on the exception (not in a try/catch block). Is "On Error Resume Next" causing this weirdness? Weirdness found: Per Rowland's and JohnH's comments i checked the Foo class: The GetEnumerator method inside of Foo didn't actually return anything! It had an empty body. That coupled with the On Error Resume Next before the loop caused the havoc! Wow this was ugly. Thanks for the clues guys!

• Aquamacs and IDLWAVE

  - by nicolavianello

  I've just installed the new Aquamacs 2.0 in my Mac Os X 10.6.3 and I'm an happy user of IDLWAVE on Aquamacs for programming in IDL. Unfortunately I run into a problem which I can't understand. I used in my configuration file to put the following (setq idlwave-surround-by-blank t) for the beautiful space around operator. This used to work till Aquamacs 2.0 preview b3 (third beta release) from that on, it stops to work and every time I type an operator (the same for '=' '<' '' etc) I got the following message Debugger entered--Lisp error: (void-variable idlwave-expand-equal) (lambda nil (interactive) (self-insert-command 1) idlwave-expand- equal -1 -1)() call-interactively((lambda nil (interactive) (self-insert-command 1) idlwave-expand-equal -1 -1) nil nil) Any help is welcommed

• Using javascript to access a json array from php

  - by celenius

  I'm trying to understand how my php script can pass an array to my javascript code. Using the following php, I pass an array: $c = array(3,2,7); echo json_encode($c); My javascript is as follows: $.post("getLatLong.php", { latitude: 500000}, function(data){ arrayData = data document.write(arrayData) document.write(arrayData[0]); document.write(arrayData[0]); document.write(arrayData[0]); }); </script> What is printed out on screen is [3,2,7][3, I'm trying to understand how json_encode works - I though I would be able to pass the array to a variable, and then access it like a normal javascript array, but it views my array as one large text string. How do ensure that it reads it like an array?

• How do I create multiple submit buttons for the same form in Rails?

  - by Angela

  I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

• MySQL parameter resource error

  - by Derek

  Here is my error: Warning: mysql_query() expects parameter 2 to be resource, null given... This refers to line 23 of my code which is: $result = mysql_query($sql, $connection) My entire query code looks like this: $query = "SELECT * from users WHERE userid='".intval( $_SESSION['SESS_USERID'] )."'"; $result = mysql_query($query, $connection) or die ("Couldn't perform query $query <br />".mysql_error()); $row = mysql_fetch_array($result); I don't have a clue what has happpened here. All I wanted to do was to have the value of the users 'fullname' displayed in the header section of my web page. So I am outputting this code immediately after to try and achieve this: echo 'Hello '; echo $row['fullname']; Before this change, I had it working perfectly, where the session variable of fullname was echoed $_SESSION['SESS_NAME']. However, because my user can update their information (including their name), I wanted the name displayed in the header to be updated accordingly, and not displaying the session value.

• Calling javascript function with arguments using JSNI

  - by jav_000

  I'm trying to integrate Mixpanel with GWT, but I have problems calling an event with a property and one value. My function to track an simple event (without values): public native void trackEvent(String eventName)/*-{ $wnd.mixpanel.track(eventName); }-*/; It works. But when I want to add some properties and values, it doesn't work properly: public native void trackComplexEvent(String eventName, String property, String value)/*-{ $wnd.mixpanel.track(eventName, {property:value}); }-*/; I have 2 problems with this: 1) Mixpanel says the property name is: "property"(yes, the name of the variable that I'm passing, not the value). 2) Mixpanel says the value is:undefined An example from mixpanel web is: mixpanel.track("Video Play", {"age": 13, "gender": "male"}); So, I guess the problem is I'm doing a wrong call or with wrong type of arguments.

• different explanation

  - by Delirium tremens

  The following code echoes 5, not 10: $global_obj = null; class my_class { var $value; function my_class() { global $global_obj; $global_obj = &$this; } } $a = new my_class; $a->my_value = 5; $global_obj->my_value = 10; echo $a->my_value; "Upon first examination, it would seem that the constructor of my_class stores a reference to itself inside the $global_obj variable. Therefore, one would expect that, when we later change the value of $global_obj-my_value to 10, the corresponding value in $a would change as well. Unfortunately, the new operator does not return a reference, but a copy of the newly created object." Please, give me a different explanation.

• How to build third party libraries with Android NDK

  - by heiko.witte

  How can I compile third party libraries with the android NDK? I am compiling a wrapper which implements the JNI functions as a shared lib, which depends on another 3rd party lib (HTK). I don't know how to setup the makefile. The following does not work: LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) include HTKLib/Android.mk LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := gaitfuncs LOCAL_SRC_FILES := gaitfuncs.c %LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog include $(BUILD_SHARED_LIBRARY) The second makefile should then build a static lib which my shared lib links to. How can I include this subdir makefile properly? Is this the correct way of doing it? And as a bonus: Are there wildcards for the LOCAL_SRC_FILES variable to take all files ending in .c for example. Thanks!

• How can I stop a default event when using a named function in addEvent?

  - by Rupert

  Normally, if I wish to stop a default event in mootools I can do this: $('form').addEvent('submit', function(e) { e.stop(); //Do stuff here } However, I don't like using an anonymous function in events because I often want to reuse the code. Lets say I have a validate function. I could do this: $('form').addEvent('submit', validate); which works fine until I want to stop the default event. validate obviously doesn't know what e is so I can't just do e.stop(). Also I've tried passing the event as a variable to validate but whenever I use a named function with parameters, the function gets called automatically on domready, rather than on the event firing. Even worse, an error is thrown when the event is fired: What am I doing wrong?

• php array to jquery array to qTip plugin.

  - by jp577

  Hi I'm trying to get a PHP array to use in some jquery script using the qTip plugin. This is my array: $descqtip[ ] = array('name' => ''.$name.'', 'description' => ''.$description.''); Here is my jquery code: <script type="text/javascript"> $(document).ready(function() { var description = <?php echo json_encode($descqtip)?>; $('#homepage_catgames h2').each(function(i){ $(this).qtip({ content: description }) }); }); </script> I know the above doesn't work, but i'm stuck on trying to get the description variable in each part of the array to their own individual tooltip. Can anyone help me? Thanks

• using subset but old variables still left

  - by user2520852

  I am working with a data set, which is basically daily usage data (let's just say variable X and Y) by different cities (about 150 cities). I have created a subset of data for only specific cities, choosing just 3 of the 150 cities. Then when I do tapply by cities, I get means for 3 cities but also get NA for all other 147 cities that was in the data set. I am using the below coding df<-read.csv(...) df_sub<-subset(df,df$City==1|df$City==3|df$City==19) X_Breakdown<-tapply(X,df_sub$City, mean, na.rm=TRUE) Print(X_Breakdown) City 1 City 2 15 NA City 3 City 4 12 NA City 5 City 6 NA NA Hope you get the idea. I would like to get a dataset that only contains the 3 cities that I'm interested in. It seems that the set of variables is encoded in R, is there a way to fix this? Kindly advise. Thanks

• Rails - Trying to query from a date range...everything from today

  - by ChrisWesAllen

  I'm trying to figure the best way to query a date range from rails...I looked around on Google but am unsure about how to use this syntax. I have a Model that has various events and I like to add to my find condition a caveat that should only show events where the field :st_date is today or later, in effect only show me data that is current, nothing that happened before today. I ran into a problem because I have no end date to stop the query, I want to query everything from today to next month. I was thinking something like @events = Event.find(:all, :conditions => ["start_date between ? and ?", date.Today, date.next_month.beginning_of_month]) but I get the error undefined local variable or method `date'...... Do I need do anything particular to use the Date class? Or is there something wrong with my query syntax? I would really appreciate any help.

• Values of Variables Matrix NumPy

  - by Max Mines

  I'm working on a program that determines if lines intersect. I'm using matrices to do this. I understand all the math concepts, but I'm new to Python and NumPy. I want to add my slope variables and yint variables to a new matrix. They are all floats. I can't seem to figure out the correct format for entering them. Here's an example: import numpy as np x = 2 y = 5 w = 9 z = 12 I understand that if I were to just be entering the raw numbers, it would look something like this: matr = np.matrix('2 5; 9 12') My goal, though, is to enter the variable names instead of the ints.

• GlassFish JDO and global object

  - by bach

  Hi, I'm thinking about the GlassFish platform for my new app. My app env. doesn't have a big volume of data to handle, but a lot of users writing/reading the same data A very volotile portion of the data updates every 200milsec by diff users. Therefore I'd like that type of data to be in memory only and accessible to the whole app My questions: How do I use a global object in memory with GF? a. use a static variable object - for that I guess I need to make sure GF is running on only 1 JVM -- how to I configure GF to run on 1 jvm? b. use HttpContext - same as a. How do I persist to the DB? a. can I use JDO interface? How do I Schedule tasks to be performed in the future (something like the task queue in GAE) thanks, J.S. Bach

• Return popupmenu selection in MATLAB using one line of code

  - by Doresoom

  I have a GUI which uses a selection from a popupmenu in another callback. Is there a way to return the selected value of the popupmenu in only one line without creating any temporary variables? I've tried several solutions, but I've only managed two lines with one temporary variable: Three lines: list=get(handles.popupmenu1,'String'); val=get(handles.popupmenu1,'Value'); str=list{val}; Two lines: temp=get(handles.popupmenu1,{'String','Value'}); str=temp{1}{temp{2}}; Can anyone shave it down to one? PS, It's a dynamic menu, so I can't just use get(handles.popupmenu1,'Value') and ignore the string component altogether.)

• Passing data between Castle Windsor's Interceptors

  - by Nhím H? Báo

  I'm adopting Castle Windsor for my WCF project and feel really amazed about this. However, I'm having a scenario that I don't really know if Castle Windsor supports. For example I have the following chained Interceptors Interceptor 1 > Interceptor 2 > Interceptor 3 > Interceptor 4 > Real method Interceptor 1 returns some data and I want that to be available in Interceptor 2 Interceptor 2 in turn does it work and returns the data that I want to make avaialbe in the 3,4, interceptor. The real case scenario is that we're having a WCF service, Interceptor 1 will parse the request header into a Header object(username, password, etc.). The latter interceptors and real method will ultilize this Header object. I know that I can use Session variable to transport data, but is it a built-in, more elegant, more reliable way to handle this?

• Can a repeated piece of regular expression create multiple groups? Such as this example...

  - by Yousui

  Hi guys, I'm using RUBY 's regular expression to deal with text such as ${1:aaa|bbbb} ${233:aaa | bbbb | ccc ccccc } ${34: aaa | bbbb | cccccccc |d} ${343: aaa | bbbb | cccccccc |dddddd ddddddddd} ${3443:a aa|bbbb|cccccccc|d} ${353:aa a| b b b b | c c c c c c c c | dddddd} I want to get the trimed text between each pipe line. For example, for the first line of my upper example, I want to get the result aaa and bbbb, for the second line, I want aaa, bbbb and ccc ccccc. Now I have wrote a piece of regular expression and a piece of ruby code to test it: array = "${33:aaa|bbbb|cccccccc}".scan(/\$\{\s*(\d+)\s*:(\s*[^\|]+\s*)(?:\|(\s*[^\|]+\s*))+\}/) puts array Now my problem is the (?:\|(\s*[^\|]+\s*))+ part can't create multiple groups. I don't know how to solve this problem, because the number of text I need in each line is variable. Anyone can help? Great thanks.
