• Access DoCmd.OpenForm Not Working

  - by user961743

  Looking for a second set of eyes to figure out my problem with an Access form filter. I created a search form, when filled in, appends search criteria to a string variable (strQuery) that is put in place to the [WhereCondition] for opening a form. However, when the script is ran, nothing comes up except for a filtered form with no records. Here is the line that opens the form: DoCmd.OpenForm "ADD_NEW_NCMR", , , strQuery Before the line is ran, strQuery equals: 1=1 AND [NCMR].[NCMR_NUM] = '12-129' The form name, and table.column combination are all correct. In fact, using the DCount function returns the result of 1, which is correct for this query, and returns the correct number for other queries as well. This makes me think that there is nothing wrong with the where condition. DCount("[NCMR_NUM]", "NCMR", strQuery)

• Getting javascript mouse position relative to website prefferably without jQuery

  - by Constructor

  I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

• Assigning a MVC Controller property from Asp.Net page

  - by JasonMHirst

  I don't know if I've understanding MVC correctly if my question makes no sense, but I'm trying to understand the following: I have some code on a controller that returns JSON data. The JSON data is populated based on a choice from a dropdown box on an Asp.Net page. I thought (incorrectly) that Session variables would be shared between the Asp.Net project and the MVC Project. What I'd like to do therefore (if this is possible), is to call a Sub on the MVC that sets a variable before the JSON query is run. I have the following: Sub SetCountryID(ByVal CountryID As Integer) Me.pCountrySelectedID = CountryID End Sub Which I can call by the following: Response.Write("http://localhost:7970/Home/SetCountryID/?CountryID=44") But this then results in a blank page - again obviouslly totally incorrect! Am I going about MVC the wrong way or do I still have a hell of a lot more learning to do? Is this even possible to do?

• Java: How do you access a sub-object of an object with no "getXXX" method to that sub-object

  - by Daxon

  I'll explain with pictures from Eclipse Debugger I have an Class called "FieldContext", (I can't edit it, it's compiled in the Java OVal API) Within "FieldContext" on the eclipse variable tab are "CompileTimeType" and "field" Q1 Is there a legend for the icons in the variables tab? like what the red box with the "F" means + yellow diamond boxes? Now I want to access the fields inside the "field" object (RedBox) .. preferably "name" But the "FieldContext" does not have a "getField()" method, yet it has a "getCompileTimeType()" method. Q2 So is there anyway to get that field object being a "SerializableField" Class from the "FieldContext"? If eclipse debugger can see/get/edit them then I hope I can do the same in Java.

• Limit on FileReference uploads?!

  - by Rudy

  Hello, I am currently uploading files in ActionScript 3 using the upload() method of the FileReference class. I built an uploader than can do simultaneous or parallel uploads, having a variable set the number of maximum uploads at a time. I noticed that for Internet Explorer I could be uploading 10 or more files simultaneously, but FireFox and Safari seems to cap the number of uploads to 2. That is, when I call the upload method on per say, 3 files, only 2 will get events back (such as ProgressEvent.PROGRESS). Only when one of the 2 uploads finishes, then the 3rd one will start. This behavior does not happen for Internet Explorer. I have tried with a large number of files, and some big files, to make sure this behavior was consistent. I was wondering if anyone noticed this behavior please, and if so, what is the reason for this behavior please? I appreciate your help, Thank you very much, Rudy

• Should we use require_once instead header location?

  - by jartaud

  Hello commnunity, i have somthing like this: (if this page needs the user to be logged) if(!isset($_SESSION['usr_id'])){ //if not a logged user $_SESSION['redir']=curPageURL();//Saving the current page for the redirection header('Location: ../Session/loginFrm.php'); } and in loginFrm.php, we do: {...after validation} if(isset($_SESSION['redir'])){ header('Location: '.$_SESSION['redir']); }else{...} in this page, they say we should use something like this instead: ... require_once '../Session/loginFrm.php'; exit(); This doesn't work for me, the session variable now contains the included page, and not the current page. What do you think about?

• Update JProgressBar from new Thread

  - by Dacto

  How can I update the JProgressBar.setValue(int) from another thread? My secondary goal is do it in the least amount of classes possible. Here is the code I have right now: **Part of the main class....** pp.addActionListener( new ActionListener(){ public void actionPerformed(ActionEvent event) { new Thread(new Task(sd.getValue())).start(); } }); public class Task implements Runnable{ int val; public Task(int value){ this.val = value; } @Override public void run() { for (int i=0; i<=value; i++){ //Progressively increment variable i pbar.setValue(i); //Set value pbar.repaint(); //Refresh graphics try{Thread.sleep(50);} //Sleep 50 milliseconds catch (InterruptedException err){} } } } pp is a JButton and starts the new thread when the JButton is clicked. pbar is the JProgressBar object from the Main class. How can I update its value?(progress) The code above in run() cannot see the pbar.

• How to use a CTabCtrl in a MFC dialog based application ?

  - by shan23

  I need to do something which i expected to be was simple - create a tab control which has 2 tabs, implying 2 modes of operation for my app. When user clicks on Tab1, he'll be presented with some buttons and textboxes, and when he clicks Tab2, some other input method. I noticed that there was a CTabCtrl class thats used in MFC to add tabs. However, once I added the tab ctrl using the UI designer, I couldn't specify how many tabs there'll be using property window. Searching on the net, I found some examples but all of them required you to derive from CtabCtrl , create 2 or more child dialogs etc and to write your own custom class. My question is, since I want to do something so basic, why couldn't I do it using the familiar Add Event handler/Add member variable wizard and then handle everything else inside my app's class ? Surely, the default CTabCtrl class can do something useful without needing to derive from it ?

• Javascript: window.onload problem

  - by Matrym

  This isn't working in IE (although it does work in FFX). Why? Using HTML in the header: <script type="application/javascript"> // And finally, let's call the code ourselves. window.onload = lbp.init; </script> And then the script: // lbp is the script's universal variable, which retains everything var lbp = {}; // The sequence of functions to trigger lbp.init = function() { alert('hi'); } Thanks in advance for your help =)

• How can this closure test be written in other languages?

  - by Jian Lin

  I wonder how the following closure test can be written in other languages, such as C and Java. Can the same result be expected also in Perl, Python, and PHP? Ideally, we don't need to make a new local variable such as x and assign it the value of i inside the loop, but just so that i has a new copy in the new scope each time. (if possible). (some discussion is in this question.) The following is in Ruby, the "1.8.6" on the first line of result is the Ruby version which can be ignored. p RUBY_VERSION $foo = [] (1..5).each do |i| $foo[i] = lambda { p i } end (1..5).each do |j| $foo[j].call() end the print out is: [MacBook01:~] $ ruby scope.rb "1.8.6" 1 2 3 4 5 [MacBook01:~] $ Contrast that with another test, with i defined outside: p RUBY_VERSION $foo = [] i = 0 (1..5).each do |i| $foo[i] = lambda { p i } end (1..5).each do |j| $foo[j].call() end the print out: [MacBook01:~] $ ruby scope2.rb "1.8.6" 5 5 5 5 5 [MacBook01:~] $

• Why is the proper "respond_to" format not getting called?

  - by humble_coder

  Hi All, I'm having a bit of an odd issue. Really too odd to type out, but here goes. Basically I have a controller that refuses to "respond_to" using javascript unless I assign my "chart.generate_xml" to a variable before the "respond_to" block like so: @xml = @chart.generate_xml(@begin_date,@end_date,1.hour) respond_to do |format| format.html format.js{ render :update do |page| page.insert_html :bottom, "chart-div", @xml #page.insert_html :bottom, "chart-div", @chart.generate_xml(@begin_date,@end_date,1.hour) end } If I remove the upper "@xml= …" portion and go with the lower "page.insert", the "format.js" section doesn't get called. And if I try to force the format with "request.format = :js", I get the javascript returned as text. I'm not doing anything special here in that method call, so I'm not sure why it would choose to respond any differently. FWIW, the method that triggers this controller action is using JS to do so, so I'm confused as to why "format.js" isn't always getting called. Thoughts? Best.

• How to check whether the form has any ShowDialog() forms open?

  - by kornelijepetak

  I have a form MainForm with several properties/methods that are accessed from another thread. At some point I might open a form AuxForm with ShowDialog() and then while that modal form is open, the other thread still modifies the MainForm's properties. This is all desired. In one of the methods accessed from another thread I need to execute some code, but only if the modal AuxForm is not open. Is there any way to check this (by using .NET WF Form properties) or I need to use a flag variable? NOTE: None of these properties/methods modify the controls (so no Invoke is required).

• Difficulties of transforming a Java program to another language (or vice versa)

  - by NomeN

  Is there anything simple Java can't do that can be done in a similar language or vice versa? Lets say you have a piece of software in language X and you rewrite it entirely to Java (or the other way around), what are the little things that would seriously hamper the translation? At first I was thinking of comprehensions or multiple exit loops, but these are easily rewritten with a for_each loop with an if statement and a local variable respectively. Maybe Exceptions? But which language does not have a similar construct? Polymorphism? But I don't see how I could show that in a few lines. I'm looking for a short and sweet example, that would give some serious headache to work around.

• Rerversing AND Bitwise.

  - by Benjamin

  Hey all, Here's the following algorithm: int encryption(int a, int b) { short int c, c2; uint8_t d; c = a ^ b; c2 = c; d = 0; while(c) { c &= c - 1; d++; } return d; } How can I find which variable a and b I should send in that function to decide of the output value of d? In other words, how can I reverse the algoritm to let's say if I want d=11?

• PHP session destroyed / lost after header

  - by ILMV

  I've got a script that sets some session values before redirecting to / using header(). I've read many posts about the $_SESSION variable being destroyed / lost after header(), even after I implemented this: // set session here session_regenerate_id(true); session_write_close(); header("Location: /"); session_start() is set in the correct places, does anyone know of anything that I might be missing? On the index.php page I have this: session_start(); print_r($_SESSION); // outputs nothing :'( The code is pretty complex so will not post it all, just snippets.

• Arrays in JavaScript

  - by caramel1991

  While reading a book about JavaScript I stumbled across an example: var names = new Array("Paul","Catherine","Steve"); var ages = new Array(31,29,34); var concatArray; concatArray = names.concat(ages); My question is, why doesn't the variable concatArray need to be define as a new Array() in order to store the concatenated data for both arrays name and ages , but when I try to treat the concatArray as an array by adding another line of code "document.write(concatArray[0])", it works just like an array and shows me the data stored in the first element. I just wonder why I'm not declaring the concatArray as a new array, yet it still works as one.

• Accessing rails flash[:notice] in a model

  I am trying to assign a message to flash[:notice] in a model observer. This question has already been asked: Ruby on Rails: Observers and flash[:notice] messages? However, I get the following error message when I try to access it in my model: undefined local variable or method `flash' for #<ModelObserver:0x2c1742c> Here is my code: class ModelObserver < ActiveRecord::Observer observe A, B, C def after_save(model) puts "Model saved" flash[:notice] = "Model saved" end end I know the method is being called because "Model saved" is printed to the terminal. Is it possible to access the flash inside an observer, and if so, how?

• Show UIView for app presentation only once in iOS

  - by André Muniz

  I need to show an UIScrollView with some pages for present the app to user when launched for the first time. My slides are working correctly, lefting the logic to present it. Is a good practice to set the UIScrollViewController as root controller and set a NSUserDefault variable to control the presentation and redirect to main controller or set the main ViewController as root normally and call the presentation view if needed is a better approach? If there is a better way to do this can someone help? Thanks.

• gem install cannot find a header file

  - by Milktrader

  Following along the github README for talib_ruby: sudo port install ta-lib Complete. Next is where the trouble begins. sudo env ARCHFLAGS="-arch PLATFORM" gem install talib_ruby -- --with-talib-include=ABSOLUTE_PATH_TO_TALIB_HEADERS --with-talib-lib=ABSOLUTE_PATH_TO_TALIB_LIBS This install fails I believe because apparently it cannot find the ta_abstract.h file talib.c:2:25: error: ta_abstract.h: No such file or directory . . . many more errors I have included in my .bash_profile file the following: export ABSOLUTE_PATH_TO_TALIB_HEADERS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/include/ta-lib export ABSOLUTE_PATH_TO_TALIB_LIBS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/lib And indeed the ta_abstract.h file is located where I'm saying in the ABSOLUTE_PATH variable assignment. What gives?

So for a css propriety of text-shadow: -4px 11px 8px rgb(30, 43, 2);, my code should be: $("#element").click(function () { var text-shadow = $("#element").css("text-shadow") }); Would it be possible to get it split like: var y = "-4px"; var x = "11px"; var blur = "8px"; color = "rgb(30, 43, 2)"; I need to somehow split the first variable to get this data. Thanx

• Is the JavaScript RegExp implicit method deprecated?

  - by Eric

  So everyone knows what I mean by "implicit methods"? They're like those default properties from the Windows COM days of yore, where you could type something like val = obj(arguments) and it would be interpreted as val = obj.defaultMethod(arguments) I just found out JavaScript has the same thing: the default method of a RegExp object appears to be 'exec', as in /(\w{4})/('yip jump man')[1] ==> jump This even works when the RegExp object is assigned to a variable, and even when it's created with the RegExp constructor, instead of /.../, which is good news to us fans of referential transparency. Where is this documented, and/or is it deprecated?

• Cursors vs Procedures in SQL

  - by CogitoErgoSum

  So, I just learned about CURSORS but still don't exactly grasp them. What is the difference between a cursor and procedure or even a function? So far from the various examples (DECLARE CURSOR ... SELECT ... FROM ...) It seems at most its a variable to hold a query. Is the data real time, or a snapshot of when the cursor was declared? i.e. I have a table with one row and one col with a value of 2. I do DECLARE CURSOR ... SELECT * FROM table1 I then insert a new row with a value of 3. When I run the cursor, would I Just get the one row from before the cursor was declared, or both rows? Thanks

• Storing the HTML output from a local PHP file into a string using file_get_contents

  - by bobo

  There is a header.php file and it contains some php codes that return HTML. I know I can use require, include to echo the results, but what I want to do is to store its processed output string into a variable. In a page, I used: $headerHTML=file_get_contents('header.php'); Then I got the PHP code output rather than the processed HTML output. I know adding http:// would help. But I prefer to keep using relative path, how can I tell the function to treat the php file correctly?
