• How can I programmatically construct the object reference?

  - by Bryan

  Lets just say that I have three textboxes: TextBox1, TextBox2, TextBox3. Normally if I wanted to change the text for example I would put TextBox1.Text = "Whatever" and so on. For what I'm doing right now I would like to something like (TextBox & "i").Text. That obviously isn't the syntax I need to use I'm just using it as an example for what I need to do. So how can I do something like this? The main reason I'm doing this is to reduce code with a loop. Please keep in mind that I'm not actually changing the text of the textboxes I'm simply using that as an example to get the point across.

• Recommendations for C# controls that can be used to create a hierarchical list of prioritised items?

  - by Mendokusai

  I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Anyone got any recommendations for controls for me to look at?

• Checkbox in a Crystal Report

  - by JosephStyons

  What is the best way to display a checkbox in a Crystal Report? Example: My report has a box for "Male" and "Female", and one should be checked. My current workaround is to draw a small graphical square, and line it up with a formula which goes like this: if {table.gender} = "M" then "X" else " " This is a poor solution, because changing the font misaligns my "X" and the box around it, and it is absurdly tedious to squint at the screen and get a pixel-perfect alignment for every box (there are dozens). Does anyone have a better solution? I've thought about using the old-style terminal characters, but I'm not sure if they display properly in Crystal. Edit: I'm using Crystal XI.

• NSInvocation: object does not implement methodSignatureForSelector

  - by Sam V

  I have this weird crash that only happens when running the app on the device (doesn't happen in the Simulator). It seems like the problem surfaces out of nowhere, as I haven't changed anything on that particular class. I had the very same issue a few days ago, and I ended up fixing it by duplicating the class, renaming it, and changing the referenced class — I haven't changed a single bit of code. So I'm trying to understand why it's doing this. I've read somewhere that usually you get this console error when the object isn't a subclass of NSObject (but it is!). Here's the exact console error message: *** NSInvocation: warning: object 0x679e0 of class 'FFProximityPickerView' does not implement methodSignatureForSelector: -- trouble ahead *** NSInvocation: warning: object 0x679e0 of class 'FFProximityPickerView' does not implement doesNotRecognizeSelector: -- abort And then it crashes. I'd be very thankful for anyone who can help me on this.

• Is it possible, with simple F# pattern matching transformations, to ignore unmatched values without

  - by Phobis

  So, I previously asked this question: http://stackoverflow.com/questions/2820234/can-someone-help-me-compare-using-f-over-c-in-this-specific-example-ip-address I was looking at the posted code and I was wondering if this code could be written without it producing a warning: let [|a;b;c;d|] = s.Split [|'.'|] IP(parseOrParts a, parseOrParts b, parseOrParts c, parseOrParts d) Is it possible to do something for the match _ pattern ot ignore? Without adding in something like Active Patterns? i want to keep the code as simple as possible... can I do this without drastically changing this code? NOTE: Warning is as follows Warning Incomplete pattern matches on this expression. For example, the value '[|_; _; _; _; _|]' may indicate a case not covered by the pattern(s).

• How to (legitimately) access files after putting self into chrooted sandbox?

  - by unknown google user

  Changing a Linux C++ program which gives the user limited file access. Thus the program chroots itself to a sandbox with the files the user can get at. All worked well. Now, however, the program needs to access some files for its own needs (not the user's) but they are outside the sandbox. I know chroot allows access to files opened before the chroot but in this case the needed files could a few among many hundreds so it is obviously impractical to open them all just for the couple that might be required. Is there any way to get at the files?

• Package <blah> does not exist error - NetBeans 6.8 & Windows 7

  - by BenMc

  I'm using NetBeans 6.8 on Windows 7. I upgraded from WinXP and NetBeans 6.7. Now my existing java web app project is no longer able to import/find the packages I've developed - I receive a 'Package ,blah. does not exist' and yet the packages do exist, worked fine in NetBeans 6.7 and the project still compiles and runs OK. I've tried changing the Java Platform/JDK from 1.6.0_10 back to JDK 1.5.0_22 but I still receive errors package does not exist. All other 'standard' libraries and packages are able to be imported and used OK ... eg Struts, Hibernate

• How can I quickly set up a RESTful site using PHP without a Framework?

  - by Sanoj

  I would like to quickly set up a RESTful site using PHP without learning a PHP Framework. I would like to use a single .htaccess-file in Apache (no mod_rewrite) or a single rule using Nginx, so I easyli can change web server without changing my code. So I want to direct all requests to a single PHP-file, and that file takes care of the RESTful-handling and call the right PHP-file. In example: The user request http://mysite.com/test The server sends all requests to rest.php The rest.php call test.php (maybe with a querystring). If this can be done, is there a free PHP-script that works like my rest.php? or how can I do this PHP-script?

• What to keep in mind when creating your own custom web services API?

  - by John Conde

  I have created a website which allows users to sign up for, and use, an online service. To help promote the website we will be have resellers who will be offering their own branded services through us. The initial plan is to allow resellers to place registration, login, and lost password forms on their own website and use an API created by us to handle these requests. I have begun outlining how I expect the API to work (and starting documenting it as well) and I want to make sure I get it right, or as close to right, as I can from the beginning as I know once you have declared a public API you want to avoid changing that API at all costs. So far I have decided: To have the user pass their account credentials with each request To require SSL for all requests What else should I be keeping in mind?

• How to read log4j output to a web page?

  - by Ran

  I have a web page, used for admin purposes, which runs a task (image fetching from a remote site). In order to be able to debug the task using the browser only, no ssh etc, I'd like to be able to read all log output from the executing thread and spit it out to the web page. The task boils down to: Changing log level for current thread at the beginning of the call and restore when the call is done. Reading all log output by current thread and storing it in a string. So in pseudocode my execute() method would look like this: (I'm using struts2) public String execute() throws Exception { turnLoggingLevelToDebugOnlyForThisThread() ... do stuff... restoreLoggingLevelForThisThread() String logs = readAllLogsByThisThread(); } Can this be done with log4j? I'm using tomcat, struts2, log4j and slf4j.

• A datastructure for Robotic Sort

  - by amit.codename13

  I am trying to solve this problem : https://www.spoj.pl/problems/CERC07S/ I have identified that i need a datastructure in which reversing operations have lesser time complexity. I tried to create one using a doubly linked list, in which (i thought) reversing can be done in O(1) by just changing a value associated with the starting and ending node which indicates the direction of traversing the list. I tried to implement it but got stuck. Maybe the approach is wrong! Are trees applicable here? If yes, how? Any ideas or links are appreciated? Thanks in advance.

• getcwd for current location based on ftp account permission

  - by John Doe

  Hello. I'm trying to make a small script that's changing the permission for specific file using a ftp connection. My problem is the absolute path. I have a ftp account wich land on the script directory (/script/). If i'm using getcwd, it will return the whole path (/home/user/public_html/script) but i need only the difference between the full path and the current path (getcwd path: /home/user/public_html/script/ ftp landing path: /script). So, how can i use getcwd to get the current directory for a ftp account? For example, if the user is landing in public_html, the path to the script will be /script/, or if he is landing inside /user, the path will be /public_html/script. Thanks

• Modifying a global variable from <a href>

  - by a_m0d

  I have created some code to popup a confirm dialog if a user tries to leave a page without saving their changes. However, I don't want the confirmation dialog to popup if the user has clicked the "Save" button. I have some code at the top of my file which looks like this: var confirmClose = false; window.onbeforeunload = function(evt) { if (confirmClose == true) { message = "There are unsaved changes on this page. Are you sure you wish to leave?"; if (typeof evt == 'undefined') { evt = window.event; } if (evt) { evt.returnValue = message; } return message; } } Further down on the page I have a link which looks like this: <a href="javascript:confirmClose=false;$('#stockForm').submit()" title="Save" class="button positive" id="stockFormSubmit">Save</a> However, this doesn't seem to work - it doesn't seem to change the value of confirmClose, and changing it to window.confirmClose didn't help either. What am I doing wrong here?

• which is better, creating a materialized view or a new table?

  - by Carson

  I have some demanding mysql queries that are needed to grap same up-to-date datasets from 5-7 mysql tables. I am thinking of creating a table or materialized view to gather all demanding columns from other tables, so as to increase performance. If I create that table, I may need to do extra insert / update / delete operation each time other tables updated. if I create materialized view, I am worrying if the performance can be greatly improved. Because data from other tables are changing very frequently. Most likely, the view may need to be created first everytime before selecting it. Any ideas? e.g. how to cache? other extra measures I can do?

• Transparent QGLWidget on top of QGraphicsView

  - by maciej.gryka

  I'm using QGraphicsView to show a 2D image and also have a separate QGLWidget window to display some 3D object. I'm dynamically changing the image displayed in `QGraphicsView' based on the rotation of the 3D object. I would like to render a semi-transparent 3D object on top of the 2D image, something like Maya 2009 used to do (notice the cube in the upper right corner of the viewport): Is it possible to do this with my current widgets? If not, how could it be done? One option I can think of would be to render everything in QGLWidget and display the 2D image as a texture on a background plane, but that seems slightly painful.

• How to define a static array without a contant size in a constructor of a class? (C++)

  - by Keand64

  I have a class defined as: class Obj { public: int width, height; Obj(int w, int h); } and I need it to contain a static array like so: int presc[width][height]; however, I cannot define within the class, so it it possible to create a pointer to a 2D array (and, out of curiosity, 3, 4, and 5D arrays), have that as a member of the class, and intitalize it in the constructor like: int ar[5][6]; Obj o(5, 6, &ar); If that isn't possible, is there any way to get a static array without a contant size in a class, or am I going to have to use a dynamic array? (Something I don't want to do because I don't plan on ever changing the size of the array after it's created.)

• php database session handling problem in IE8!

  - by psyb0rg

  I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

• UIButton custom font vertical alignment

  - by Willshaw Media

  I've got a UIButton which uses a custom font, which is set when my view loads: - (void)viewDidLoad { [super viewDidLoad]; self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ]; } The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment. I'm getting the same issue on a Table Cell with a custom font too. Do I need to tell the view somewhere that the custom font is not as tall as other fonts? EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App

• Rejigging a floating point equation ...

  - by Jamie

  I'd like to know if there is a way to improve the accuracy of calculating a slope. (This came up a few months back here). It seems by changing: float get_slope(float dXa, float dXb, float dYa, float dYb) { return (dXa - dXb)/(dYa - dYb); } to float get_slope(float dXa, float dXb, float dYa, float dYb) { return dXa/(dYa - dYb) - dXb/(dYa - dYb); } might be an improvement. Suggestions? Edit: It's precision I'm after, not efficiency.

• Combining 2 PHP frameworks that both implement __() internationalization function

  - by mclin

  Never had a question I couldn't google until now, and it may be a doozy: I have a PHP site that combines Wordpress with Kohana - Wordpress for the blog, and Kohana for the custom functionality. This is done using a Wordpress plugin that stitches them together. This works great except they both define a __() internationalization function, with different arguments etc. so once wordpress has overridden kohana's __(), if kohana calls __() it explodes. I'm not that familiar with PHP so this might be naive, but shouldn't this stuff be namespaced? Is there anyway other than changing the source of one or the other framework to allow them to call their own respective __()?

• PHP complete sample website source

  - by MarceloRamires

  I'm new to PHP, and it appears that the way I learn the fastest is to study a new language a well developed complete program (or website, in this case) changing stuff seeing what happens and consulting books. There are lots of recommendations of books all around, and that's pretty much covered. I'd like to find the sourcecode of a website. Either a well known, well developed open-source website, or a sample sourcecode of a complete website (maybe one used in a book or something). Everyone says they should find the way they learn better.. Well, that's mine. PS.: By complete I mean having several common functionalities (such as login), database connection, use of security conventions, maybe a popular framework, and being up-to-date.

• How to remove htmlentities() values from the database?

  - by Chris

  Long before I knew anything - not that I know much even now - I desgined a web app in php which inserted data in my mysql database after running the values through htmlentities(). I eventually came to my senses and removed this step and stuck it in the output rather than input and went on my merry way. However I've since had to revisit some of this old data and unfortunately I have an issue, when it's displayed on the screen I'm getting values displayed which are effectively htmlentitied twice. So, is there a mysql or phpmyadmin way of changing all the older, affected rows back into their relevant characters or will I have to write a script to read each row, decode and update all 17 million rows in 12 tables?

• WPF: How to efficiently update an Image 30 times per second

  - by John

  Hello, I'm writing a WPF application that uses a component, and this component returns a pointer (IntPtr) to pixels of a bitmap (stride * height). I know in advance that the bitmap is a 24bits rgb, its width and height. Updating the Image control with these bitmaps makes up a video to the user, but I'm not sure what's the most efficient way to do that, most of the time the CPU usage goes to 75%+ and memory changing from 40mb to 500mb and the nI think GC starts to work and then it drops again to 40mm. The app starts to not be responsive. What shoud I do? thanks!

• capistrano deployment with use_sudo=true - permissions problem

  - by Pavel K.

  i am trying to do a deployment with capistrano to newly installed Ubuntu server i am deploying to directory /var/www, owned by root, so i need to set use_sudo to true while i execute commands with run "#{try_sudo} command" without problem, svn checkout doesn't work with sudo prefix i try set :deploy_via, :export and it throws Can't make directory '/var/www/pr_name/releases/20091217171253': Permission denied during checkout i imagine adding "try_sudo" prefix to "svn export" would help, but where can i edit the one it uses in deploy_via? -- if on other hand i don't use use_sudo, and set /var/www/ directory ownership to myuser, i still cannot deploy - some of my deployment commands set folders ownership to apache user www-data and then i get something like: changing ownership of `/var/www/pr_name/current/specificdirectory': Operation not permitted which, if i understand correctly, has to be done with sudo

• CakePHP save without form
