  • Access VBA question: Change the query being referenced by a function, depending on context

    - by Tara Amatista
    I have a custom function in Access2007 that hinges on grabbing data out of a specific query. It opens Outlook, creates a new email and populates the fields with specific addresses and data taken from the query ("DecisionEmail"). Now I want to make a different query ("RequestEmail") and have it populate the email with that data. So all I have to do is change this line: Set MailList = db.OpenRecordset("DecisionEmail") and that's where I get stumped. This is my desired result: If the user is on Form_Decision and clicks the button "Send email", "DecisionEmail" will get plugged into the function and that data will appear in the email. If the user on Form_SendRequest and clicks the button "Send email", "RequestEmail" will instead get plugged in. The reason that these are different queries is because they contain very different information that is smudged about in different ways. However, since it's just one little thing that needs to change in the function code, I don't think a brand new function is a good idea. My last resort would be to make a brand new function and use the Conditions field in the Macro interface to choose between them, but I have a feeling there's a more elegant solution possible. I have a vague notion of setting the query names as variables and using an If statement but I just don't have the mental vocabulary for thinking through this.

  • Load more function in Javascript

    - by erastusnjuki
    EDIT: This question was initially too general, I think. So What I really need is a very good tutorial on how to implement the Load More function on Safari for iPhone just like the Twitter website(mobile.twitter.com) does. Just a wordpress plugin won't really help. But if the plugin is well explained, like if it is wptouch, home(that also has this function) that can also do. I know that it doesn't really matter that it is being displayed on a mobile device, but the point I am stressing is that if such a function is well explained, then it will be up to me to know how to customize it to suit me. I am using a javascript function to load entries that come from the database dynamically, so that content opens in the same page (like with twitter(tweets feed) and facebook(news feed)). The php/html version(That opens a page in a new tab) is echo '<a href="http://'. $_SERVER['HTTP_HOST'] .'/'.$domain_page.'?form='.$form_id.'&page='.($page+1).'">Load more entries&rsaquo; </a>'; The javascript/ajax version: <div id="call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="ajax-load-more"> <img id="spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="spin" src="<?php bloginfo('template_directory'); ?>/images/main-ajax-loader.gif" style="display:none" alt="" /> <a class="ajax" href="javascript:$ajax_hv('#spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeIn(200); $ajax_hv('#ajaxentries_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').load('form='<? echo $form_id; ?>&page=<?php echo $page+1;?>', {}, function(){ $ajax_hv('#call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeOut();})">Load more entries... </a>

  • Get ID of clicked on element in function

    - by skerit
    I want to get the ID of an element I click on. I put the function in the onclick element, like this: <a id="myid" class="first active" onclick="markActiveLink();" href="#home">Home</a> And this is in the function: function markActiveLink() { alert($(this).attr("id")); } This doesn't work, as it says it isn't defined. Does it really forget about the ID, do I have to type it in the onclick?

  • JNI: dll function works ok in C++ main, but not with dll wrapper

    - by Joseph Lim
    I have an a.dll (not modifiable as i do not have the source) with a function bool openPort(DWORD mem).I wrote a c++ main, loaded this dll using LoadLibrary, and the function works well.It returns true. Now, I need to call this function from Java via JNI. I wrote another b.dll with a function like so JNIEXPORT void JNICALL Java_MyClass_openPortFunc (JNIEnv *env, jobject obj, jint pMemPhy) { hInstLibrary = LoadLibrary("a.dll"); typedef bool (*openPort)(DWORD); openPort _openPort; _openPort = (openPort)GetProcAddress(hInstLibrary, "openPort"); DWORD memAddr = 0xda000; if(_openPort(memAddr)){ cout << "ok" << endl; }else{ cout << "failed " << endl; } } This however, causes the openPort to return false despite using the same parameters. I hope someone can advise me. Thank you. :)

  • Python function argument scope (Dictionaries v. Strings)

    - by Shaun Meyer
    Hello, given: foo = "foo" def bar(foo): foo = "bar" bar(foo) print foo # foo is still "foo"... foo = {'foo':"foo"} def bar(foo): foo['foo'] = "bar" bar(foo) print foo['foo'] # foo['foo'] is now "bar"? I have a function that has been inadvertently over-writing my function parameters when I pass a dictionary. Is there a clean way to declare my parameters as constant or am I stuck making a copy of the dictionary within the function? Thanks!

  • Call to a member function get_segment() error

    - by hogofwar
    I'm having this problem with this piece of PHP code: class Core { public function start() { require("funk/funks/libraries/uri.php"); $this->uri = new uri(); require("funk/core/loader.php"); $this->load = new loader(); if($this->uri->get_segment(1) != "" and file_exists("funk/pages/".$uri->get_segment(1).".php")){ Only a snippet of the code The best way I can explain it is that it is a class calling upon another class (uri.php) and i am getting the error: Fatal error: Call to a member function get_segment() on a non-object in /home/eeeee/public_html/private/funkyphp/funk/core/core.php on line 11 (the if($this-uri-get_segment(1) part) I'm having this problem a lot and it is really bugging me. the library code is: <?php class uri { private $server_path_info = ''; private $segment = array(); private $segments = 0; public function __construct() { $segment_temp = array(); $this->server_path_info = preg_replace("/\?/", "", $_SERVER["PATH_INFO"]); $segment_temp = explode("/", $this->server_path_info); foreach ($segment_temp as $key => $seg) { if (!preg_match("/([a-zA-Z0-9\.\_\-]+)/", $seg) || empty($seg)) unset($segment_temp[$key]); } foreach ($segment_temp as $k => $value) { $this->segment[] = $value; } unset($segment_temp); $this->segments = count($this->segment); } public function segment_exists($id = 0) { $id = (int)$id; if (isset($this->segment[$id])) return true; else return false; } public function get_segment($id = 0) { $id--; $id = (int)$id; if ($this->segment_exists($id) === true) return $this->segment[$id]; else return false; } } ?>

  • JavaScript: How is "function x() {}" different from "x = function() {}" ?

    - by jleedev
    In the answers to this question, we read that function f() {} defines the name locally, while [var] f = function() {} defines it globally. That makes perfect sense to me, but there's some strange behavior that's different between the two declarations. I made an HTML page with the script onload = function() { alert("hello"); } and it worked as expected. When I changed it to function onload() { alert("hello"); } nothing happened. (Firefox still fired the event, but WebKit, Opera, and Internet Explorer didn't, although frankly I've no idea which is correct.) In both cases (in all browsers), I could verify that both window.onload and onload were set to the function. In both cases, the global object this is set to the window, and I no matter how I write the declaration, the window object is receiving the property just fine. What's going on here? Why does one declaration work differently from the other? Is this a quirk of the JavaScript language, the DOM, or the interaction between the two?

  • No getdate() function in Enterprise PostgreSQL

    - by Suezy
    Hi guys, do you have any idea on how to have getdate() function in enterprise postgresql? I upgraded to EDB-PSQL, and now when I tried to restore old data from the free PSQL, it returns error on some tables since there is no getdate(). I believe this should automatically be created upon creating new database? But it didn't. :( Only now() function. Can I create the function instead? Help!

  • Add function to existing JQuery plugin

    - by kralco626
    Is it possible to add a function to a plugin without modifying the actual plugin? Can I do something like this in my site's js file? $.fn.Watermark.Refresh = function() { $.Watermark.HideAll(); $.Watermark.ShowAll(); } or (function($){ $.fn.Watermark.Refresh = function() { $.Watermark.HideAll(); $.Watermark.ShowAll(); }; })(jQuery); neither worked, the first says $ is undefined, the second that jQuery is undefined... ideas? Solution: Either method works, just include the jquery file before the site js file.

  • Linking to a section of a site that is hidden by a hide/show JavaScript function

    - by hollyb
    I am using a bit of JavaScript to show/hide sections of a site when a tab is clicked. I'm trying to figure out if there is a way I can link back to the page and have a certain tab open based on that link. Here is the JS: var ids=new Array('section1','section2','section3','section4'); function switchid(id, el){ hideallids(); showdiv(id); var li = el.parentNode.parentNode.childNodes[0]; while (li) { if (!li.tagName || li.tagName.toLowerCase() != "li") li = li.nextSibling; // skip the text node if (li) { li.className = ""; li = li.nextSibling; } } el.parentNode.className = "active"; } function hideallids(){ //loop through the array and hide each element by id for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id document.getElementById(id).style.display = 'none'; } function showdiv(id) { //safe function to show an element with a specified id document.getElementById(id).style.display = 'block'; } And the HTML <ul> <li class="active"><a onclick="switchid('section1', this);return false;">One</a></li> <li><a onclick="switchid('section2', this);return false;">Two</a></li> <li><a onclick="switchid('section3', this);return false;">Three</a></li> <li><a onclick="switchid('section4', this);return false;">Four</a></li> </ul> <div id="section1" style="display:block;"> <div id="section2" style="display:none;"> <div id="section3" style="display:none;"> <div id="section4" style="display:none;"> I haven't been able to come up with a way to link back to a specific section. Is it even possible with this method? Thanks!

  • Using list() to extract a data.table inside of a function

    - by Nathan VanHoudnos
    I must admit that the data.table J syntax confuses me. I am attempting to use list() to extract a subset of a data.table as a data.table object as described in Section 1.4 of the data.table FAQ, but I can't get this behavior to work inside of a function. An example: require(data.table) ## Setup some test data set.seed(1) test.data <- data.table( X = rnorm(10), Y = rnorm(10), Z = rnorm(10) ) setkey(test.data, X) ## Notice that I can subset the data table easily with literal names test.data[, list(X,Y)] ## X Y ## 1: -0.8356286 -0.62124058 ## 2: -0.8204684 -0.04493361 ## 3: -0.6264538 1.51178117 ## 4: -0.3053884 0.59390132 ## 5: 0.1836433 0.38984324 ## 6: 0.3295078 1.12493092 ## 7: 0.4874291 -0.01619026 ## 8: 0.5757814 0.82122120 ## 9: 0.7383247 0.94383621 ## 10: 1.5952808 -2.21469989 I can even write a function that will return a column of the data.table as a vector when passed the name of a column as a character vector: get.a.vector <- function( my.dt, my.column ) { ## Step 1: Convert my.column to an expression column.exp <- parse(text=my.column) ## Step 2: Return the vector return( my.dt[, eval(column.exp)] ) } get.a.vector( test.data, 'X') ## [1] -0.8356286 -0.8204684 -0.6264538 -0.3053884 0.1836433 0.3295078 ## [7] 0.4874291 0.5757814 0.7383247 1.5952808 But I cannot pull a similar trick for list(). The inline comments are the output from the interactive browser() session. get.a.dt <- function( my.dt, my.column ) { ## Step 1: Convert my.column to an expression column.exp <- parse(text=my.column) ## Step 2: Enter the browser to play around browser() ## Step 3: Verity that a literal X works: my.dt[, list(X)] ## << not shown >> ## Step 4: Attempt to evaluate the parsed experssion my.dt[, list( eval(column.exp)] ## Error in `rownames<-`(`*tmp*`, value = paste(format(rn, right = TRUE), (from data.table.example.R@1032mCJ#7) : ## length of 'dimnames' [1] not equal to array extent return( my.dt[, list(eval(column.exp))] ) } get.a.dt( test.data, "X" ) What am I missing? Update: Due to some confusion as to why I would want to do this I wanted to clarify. My use case is when I need to access a data.table column when when I generate the name. Something like this: set.seed(2) test.data[, X.1 := rnorm(10)] which.column <- 'X' new.column <- paste(which.column, '.1', sep="") get.a.dt( test.data, new.column ) Hopefully that helps.

  • JavaScript: function returning NAN

    - by Michael
    I'm working on a codecademy.com lesson with instructions to write the calculateTotal function below. When I click run, it's returning NaN. Anyone know what's wrong with the calculateTotal function as I wrote it that's making it return NaN. Note, I understand that NaN means not a number... // runner times var carlos = [9.6,10.6,11.2,10.3,11.5]; var liu = [10.6,11.2,9.4,12.3,10.1]; var timothy = [12.2,11.8,12.5,10.9,11.1]; // declare your function calculateTotal here var calculateTotal = function(raceTimes){ var totalTime; for(i = 0; i < raceTimes.length; i++){ totalTime += raceTimes[i]; return totalTime; } }; var liuTotal = calculateTotal(liu); console.log(liuTotal);

  • Javascript function question

    - by Raj
    I searched but couldn't find an answer to this seemingly easy question, so... Suppose I have a loop in which I need to set callbacks. My callback function looks like this: function callback(var1) { // code } Now my loop is something like this: for( //condition) { var x = something_different_each_time; document.getElementById('foo').addEventListener('click', function() { callback(x); }, false); } Now it looks like even if the loop runs n times, the anonymous function is compiled only once -- and hence every invocation of callback is called with the same argument (even though x varies in the loop every time). I must be missing something here.. any help is greatly appreciated! :)

  • JSON to javaScript array

    - by saturn_research
    I'm having a problem handling JSON data within JavaScript, specifically in regards to using the data as an array and accessing and iterating through individual values. The JSON file is structured as follows: { "head": { "vars": [ "place" , "lat" , "long" , "page" ] } , "results": { "bindings": [ { "place": { "type": "literal" , "value": "Building A" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "10.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-1.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/a.html" } } , { "place": { "type": "literal" , "value": "Building B" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "11.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-2.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/b.html" } } , { "place": { "type": "literal" , "value": "Building C" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "12.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-3.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/c.html" } } ] } } I want to be able to convert this into a JavaScript array as follows in order that I can iterate through it and pull out the values for each location in order: var locations = [ ['Building A',10.3456,-1.2345,'http://www.example.com/a.html'], ['Building B',11.3456,-2.2345,'http://www.example.com/b.html'], ['Building C',12.3456,-3.2345,'http://www.example.com/c.html'] ]; Does anyone have any advice on how to achieve this? I have tried the following, but it picks up the "type" within the JSON, rather than just the value: $.each(JSONObject.results.bindings, function(i, object) { $.each(object, function(property, object) { $.each(object, function(property, value) { value; }); }); }); Any help, suggestions, advice or corrections would be greatly appreciated.

  • How to write an R function that evaluates an expression within a data-frame

    - by Prasad Chalasani
    Puzzle for the R cognoscenti: Say we have a data-frame: df <- data.frame( a = 1:5, b = 1:5 ) I know we can do things like with(df, a) to get a vector of results. But how do I write a function that takes an expression (such as a or a > 3) and does the same thing inside. I.e. I want to write a function fn that takes a data-frame and an expression as arguments and returns the result of evaluating the expression "within" the data-frame as an environment. Never mind that this sounds contrived (I could just use with as above), but this is just a simplified version of a more complex function I am writing. I tried several variants ( using eval, with, envir, substitute, local, etc) but none of them work. For example if I define fn like so: fn <- function(dat, expr) { eval(expr, envir = dat) } I get this error: > fn( df, a ) Error in eval(expr, envir = dat) : object 'a' not found Clearly I am missing something subtle about environments and evaluation. Is there a way to define such a function?

  • Javascript global object calls function?

    - by Troels
    Hello stackoverflow I have a very odd problem with javascript. My code is rather long so here is an example of the structure and the problem: var x = new function f() { this.id = ""; } function g(obj) { if (x.id == "") { ... obj.firstChild.setAttribute("onclick", "javascript:o();"); ... x.id = obj.id; } else if (x.id != obj.id) { ... x.id = ""; g(obj); } } function o() { ... if (something == something) { ... } else { ... x.id = ""; // if-statement of the g() function is called here? } } As you can see, the if-statement of the g() function is for some reason called or re-run upon x.id being changed. I simply cannot understand this, because they are not in the same scope, and changing a variable should under no circumstances trigger anything? Any help would be greatly appreciated.
