• File upload with tdo-miniforms not working

  - by user338109

  I am using the TDO-miniforms plugin for wordpress. I have a form set up that lets the user submit files. The files are successfully uploaded to the tmp-folder, but once the post is created they are not copied into the allocated post folder. The only thing that is created in the folder with a post id is a file called array. It seems like the file holds the binary data of the uploaded files. The “correct” urls are appended to the post content I am running wordpress 2.9.2 on snow leopard using Mamp.

• Need help with some C# Counting Code

  - by kaywai

  Hi, I'm trying to code a counter in Ninjatrader which uses C# as its programming language. I would like this counter to commence counting upon the completion of the first counter and once it commences counting to consider only the new condition when counting. So, the first counter commences when Close[0] < Close[4]. The second counter commences ONLY after the first counter has reached 9 and its condition for counting is Close[0] <= Low[2]. I don't know how to write the part of the code where the second counter commences counting and its counts are independent of the first counter reaching 9.

• Portrait vs Landscape Launch Images

  - by andrewx

  An iPad app can support inclusion of launch images in both orientations; presumably, if your app supports auto-rotation, then this would suggest to me that if the user launches an app while the device is in Landscape mode, then the Landscape launch image is used. But in all the apps I've built and released, this has never been the case. Never once has the Landscape launch image appeared, only the Portrait. After loading, the app will auto-rotate to whatever orientation the device is in, but at launch, it assumes you are in Portrait. Always. Why? I have seen many other apps in the store that behave this way, but then there are some seem to always automatically know immediately at first launch, from that first launch image, that you are in Landscape, if that's the case. How is this done?

• Core Data-Linking one-to-many relationships

  - by Stelmate

  I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

• Embarassing C++ question regarding const

  - by Neil Butterworth

  My comments on this answer got me thinking about the issues of constness and sorting. I played around a bit and reduced my issues to the fact that this code: #include <vector> int main() { std::vector <const int> v; } will not compile - you can't create a vector of const ints. I suppose I should have known this, but I've never needed to create such a thing before. However, it seems like a useful construct to me, and I wonder if there is any way round this problem - I want to add things to a vector (or whatever), but they should not be changed once added. There's probably some embarrassingly simple solution to this, but it's something I'd never considered before.

• What is this C function supposed to do based on description?

  - by user1261445

  unsigned int hex_c0c0c0c0(): Allowed operators: + - = & | ~ << ! >> Allowed constants: 1 2 4 8 16 Return 0xc0c0c0c0 The above is the description I have been given and I have to write the code for it. Can someone tell me what exactly the function is supposed to do? All the description says is what I have pasted above, so I'm not sure what my goal is. I'm sure it is an easy enough function to program on my own, but it would help if someone could tell me what the function is supposed to do, and maybe provide sample input/output so that I know my code is working correctly once I program this. Thanks.

• How to make an element slide with the viewport as it scrolls?

  - by alex

  I've Googled for this but must be using the wrong keywords. Basically I want to use the effect that Magento and now Stack Overflow uses. That is, there is an element in a column, and when you scroll down, it sticks to the top of the viewport. And once scrolled up again, it goes back into the normal page flow. This Ask A Question is a good page for example. Scroll down and watch the "How to Format" element come down (might need to make your viewport smaller if you have a large screen to see the effect). I've noticed it is setting position: fixed in the CSS. The JavaScript however is obfuscated. What's the easiest way to achieve this effect? Is there a jQuery plugin available?

• AtomicInteger for limited sequnce generation

  - by satish

  How can we use AtomicInteger for limited sequence generation say the sequence number has to be between 1 to 60. Once the sequece reaches 60 it has to start again from 1. I wrote this code though not quite sure wether this is thread safe or not? public int getNextValue() { int v; do { v = val.get(); if ( v == 60) { val.set(1); } } while (!val.compareAndSet(v , v + 1)); return v + 1; }

• Managing a list of threads

  - by Satanlike

  Hi, I have an application (.Net 3.5) which creates threads to write something to the database so that the GUI does not block. All created threads are added to a list, so that I can wait (Thread.Join) for each thread when the application is closed (maybe not all threads are finished when the application is closed, so the app must wait for them). Because of the list I get some serious problems if there are too many threads created (OutOfMemoryException). I tried removing finished threads from the list, but somehow that didn't work. Are there better ways to manage a list of threads, so I can remove them once they are finished?

• how to use javascript to download a file on Chrome without Chrome auto renaming file to "download"? [duplicate]

  - by user3688566

  This question already has an answer here: Is there any way to specify a suggested filename when using data: URI? 11 answers I use javascript to generate a file and download. It seems that depending on the version of chrome, the download file names can be auto renamed to 'download'. is there a way to avoid it? this is my code: var link = document.createElement("a"); link.setAttribute("href", 'data:application/octet-stream,' + 'file content here'); link.setAttribute("download", 'file1.txt'); link.click(); This is not a duplicated question because i am using the latest chrome and the previously suggested hyperlink is exactly what i am using. I think chrome v34 works fine. but once my chrome autoupdated to v35, it went back to 'download' file name.

• WPF Button on or off coloured state

  - by wonea

  I'm trying to create a set of button which have an off or on state, much a checkbox without the check. Ideally I want the colour to change to represent the two different states off(red), green(on). I've tried setting a control template but this only changes the colour for a selection, then reverts back to it's original colour once the mouse leaves the button's vicinity. <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="True"> <Setter Property="Background" TargetName="Background" Value="Green"/> </Trigger> </ControlTemplate.Triggers>

• AS3/AIR: Managing Run-Time Image Data

  - by grey

  I'm developing a game with AS3 and AIR. I will have a large-ish quantity of images that I need to load for display elements. It would be nice not to embed all of the images that the game needs, thereby avoiding having them all in memory at once. That's okay in smaller projects, but doesn't make sense here. I'm curious about strategies for loading images during run time. Since all of the files are quite small and local ( in my current project ) loading them on request might be the best solution, but I'd like to hear what ideas people have for managing this. For bonus points, I'm also curious about solutions for loading images on-demand server-side as well.

• Configure WCF Service Behavior using database

  - by Achhar

  We use database to centralize our configuration. As part of it, I want to store the standard service behaviors configuration like expose service metatdata, service debug, service throttling for a service inside database rather than in web/app.config. I was planing to store the configuration for a behavior in database as XML. For e.g. <serviceDebug includeExceptionDetailsinFault=true / What I am struggling with is once I read this XML from database how do I create ServiceDebugBehavior instance from it and apply it to my service host? I have tried using XML Serializer but didn't had success. Any thoughts on how this could be achieved or any alternate solutions?

• Obtain distances to nearest landmarks (Mall, Hospital, and Airport etc.) using google map

  - by user227290

  I am working on a project in which I have around 100000 addreses in major cities in India(it is a table in a database). I want to know if it is possible to obtain the distances to to nearest landmarks (Mall, Hospital, and Airport etc.). Ideally I want these distances to be mergeed to the parent table. We have Java and Php coders to get it done once we find out how to go about it. Any pointers will be of great help. Thank you.

• finding the value of radio button with jquery

  - by oo

  i have this code below to show different divs when i choose certain radio buttons: if ($("input[@name='exerciseRB']:checked").val() == 'New') { $("#newExercise").show(); $("#existingExercise").hide(); } else { $("#newExercise").hide(); $("#existingExercise").show(); } at first, i just had two radio buttons (both named exerciseRB and everything works fine. Now, later in my web page i added two new radio buttons (with the name lessonRB). The issue is that once i added these other new radio buttons when i look up this in firebug: $("input[@name='exerciseRB']:checked") i actually get an array back with both the exerciseRB item as well as the lessonRB item. Its almost as if the @name='exerciseRB' is being ignored. any ideas here?

• How to manage memory for ios with large csv files?

  - by Pell000

  I'm new to ios development, and I'm running into issues relating to memory management and my approaches to dealing with large datasets. Right now, I am loading the csv files and storing the relevant data as objects in memory at app initialization. Some of the csv files are larger than 1MB, and in total, my app uses about 180MB of memory. This is obviously way too high of a number (unless the info I found is wrong and this is an acceptable number, then please let me know). I feel as though there is a fundamental flaw in my approach: is there a way I can avoid storing the csv files in the project itself? Or, is there a kind of "lazy" loading I can do so that I can simply look up info in the csv file, as opposed to loading all of the data from it at once? Any help would do. I think that I need a new perspective in how to manage this more efficiently.

• Trying to zoom in on an arbitrary rect within a screen-aligned quad.

  - by mos

  I've got a screen-aligned quad, and I'd like to zoom into an arbitrary rectangle within that quad, but I'm not getting my math right. I think I've got the translate worked out, just not the scaling. Basically, my code is the following: // // render once zoomed in glPushMatrix(); glTranslatef(offX, offY, 0); glScalef(?wtf?, ?wtf?, 1.0f); RenderQuad(); glPopMatrix(); // // render PIP display glPushMatrix(); glTranslatef(0.7f, 0.7f, 0); glScalef(0.175f, 0.175f, 1.0f); RenderQuad(); glPopMatrix(); Anyone have any tips? The user selects a rect area, and then those values are passed to my rendering object as [x, y, w, h], where those values are percentages of the viewport's width and height.

• Querying Postgresql with a very large result set

  - by sanity

  In an application I need to query a Postgres DB where I expect tens or even hundreds of millions of rows in the result set. I might do this query once a day, or even more frequently. The query itself is relatively simple, although may involve a few JOINs. My question is: How smart is Postgres with respect to avoiding having to seek around the disk for each row of the result set? Given the time required for a hard disk seek, this could be extremely expensive. If this isn't an issue, how does Postgres avoid it? How does it know how to lay out data on the disk such that it can be streamed out in an efficient manner in response to this query?

• nextSibling issue, should be simple

  - by SoLoGHoST

  Ok, I'm trying to come to grips with this nextSibling function in JS. Here's my issue within the following code... var fromRow = document.getElementById("row_1"); while(fromRow.nodeType == 1 && fromRow.nextSibling != null) { var fRowId = fromRow.id; if (!fRowId) continue; // THIS ONLY gets done once and alerts "row_1" ONLY :( alert(fRowId); fromRow = fromRow.nextSibling; } Ok can someone please tell me what is wrong with this code? There are siblings next to this document.getElementById("row_1"); element for sure as I can see them, and they all have id attributes, so why is it not getting the id attributes of the siblings?? I don't get it. row_1 is a TR element, and I need to get the TR elements next to it within this table, but for some reason, it only gets the 1 element that I can already get using document.getElementById, arggg. Thanks guys :)

• Throwing an AggregateException in my own code

  - by Pat

  How should I go about collecting exceptions and putting them into an AggregateException to re-throw? For my specific code, I have a loop and will have zero or more exceptions thrown from a part of the code. I was hoping to just add the new exceptions to the AggregateException as they arise, but the documentation sort of indicates that it should be constructed with all the Exceptions at once (there is no method to add an Exception to the object). And what about creating a new AE every time and just including the previous AE in the list of exceptions? Seems a hokey way to do it. Any better ideas?

• Optimal diff between object lists in Java

  - by Philipp

  I have a List of Java objects on my server which is sent to the client through some serialization mechanism. Once in a while the List of objects gets updated on the server, that is, some objects get added, some get deleted and others just change their place in the List. I want to update the List on the client side as well, but send the least possible data. Especially, I don't want to resend Objects which are already available on the client. Is there a library available which will produce some sort of diff from the two lists, so that I can only send the difference and the new Objects accross the wire? I have found several Java implementation of the unix diff command, but this algorithm is unpractical for order changes. ie. [A,B,C] - [C,B,A] could be sent as only place changes [1-3] [3-1], while diff will want to resend the whole A and C objects (as far as I understand).

• EXC_BAD_ACCESS iPhone Development

  - by gkres121

  Sorry, this could be a simple fix, as I am new to iPhone Development. In my Delegate, after pressing the create profile button, the create profile view is pushed: -(void) createProfile_clicked:(id)sender { AddNewProfile *create = [[AddNewProfile alloc] init]; [self.window addSubview:create.view]; [self invisibleCreateProfileBar]; AddNewProfile *controller = [[AddNewProfile alloc] initWithNibName:@"AddNewProfile" bundle:[NSBundle mainBundle]]; [ self.navigationController pushViewController:controller animated:YES ]; currentController=controller; } Then in the AddNewProfile.m: - (IBAction)backgroundTap:(id)sender { if([nameField isFirstResponder]){ [nameField resignFirstResponder]; } if([ageField isFirstResponder]){ [ageField resignFirstResponder]; } if([doctorNameField isFirstResponder]){ [doctorNameField isFirstResponder]; } if([doctorNumberField isFirstResponder]){ [doctorNumberField resignFirstResponder]; } } This leads to a exc_bad_access error every time the FirstResponder is ever messed with, with any of my controls. I can select a control(text box), but once I click out of one, it crashes. Any help would be greatly appreciated.

• How does linq decide between inner & outer joins

  - by user287795

  Hi Usually linq is using an left outer join for its queries but on some cases it decides to use inner join instead. I have a situation where that decision results in wrong results since the second table doesn't always have suitable records and that removes the records from the first table. I'm using a linqdatasource over a dbml where the relevant tables are identical but one holds historical records removed from the first. both have the same primary key. and I'm using a dataloadoption to load both tables at once with out round trips. Would you explain why linq decided to use an inner join here? Thanks

• Find all possible partitions of n elements with k-sized subsets, where two elements share same set o

  - by ypnos

  I have n=32 elements that need to be partitioned into 8 sets, each set has to hold exactly k=4 elements. I need to find all possible partitions with the constraint that each pair of elements only shares the same set once. So if I start with [1 2 3 4] [5 6 7 8] [...], all consecutive partitions cannot hold e.g. [1 2 X X] or [X X 1 3]. sets are unordered. Close to this problem are the stirling numbers of the second kind. However, they only solve the problem for arbitrarily sized sets.

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??
