• How can I change text on a win32 window?

  - by Will

  Looking for hints, tips and search terms for changing the text on a win32 window from C#. More specifically, I'm trying to change the text on the print dialog from "Print" to "OK", as I am using the dialog to create a print ticket and not do any printing. How can I find the dialog's window handle? Once I've got it, how would I go about finding the button in the child windows of the form? Once I've found that, how would I change the text on the button? And how can I do all this before the dialog is shown? There's a similar question here, but it points to a CodeProject article that is waaay more complex than needed and is taking me a bit longer to parse through than I'd like to spend on this. TIA.

• Installing PostgreSQL on Windows

  - by Ross

  I'm in a bit of a mess here. I installed PostgreSQL on my Vista computer a couple of days ago but then when asked to enter the password for the postgre user account I couldn't remember it (allegedly I was asked during setup but I don't remember that). Anyway, so I uninstalled Pg with the intention of reinstalling it, removed the user account, it's /Users/ directory and it's special privelleges ("Advanced user profile properties") but when I come to install Pg it seems to think the account still exists as when I supply a password during setup it says that it is not the correct password - meaning that the account still exists somewhere. Is there anyway I can recover this?

• What if I have an API method and a contoller/view method with the same name in RoR?

  - by Chad Johnson

  Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

• Best implementation for MySQL replication with Rails 3?

  - by vonconrad

  We're looking at potentially setting up replication for our primary MySQL database, and while setting up the replication seems pretty straight-forward, the application implementation seems a bit murkier. My first idea would be to set up a master-slave configuration and RW-splitting, with all write queries (CREATE, INSERT, UPDATE) going to master, and all read queries (SELECT) going to slave. Having read up on it, it seems that there are essentially two options for how to implement this with our app: Using an independent middleware layer for all MySQL connections, such as MySQL proxy or DBSlayer. However, the former is in Alpha and the latter has limited documentation. Using a Ruby-based gem/plugin, such as Octopus to achieve RW-splitting in the framework. If we wanted to go with a master-slave setup, what you recommend moving forward? The other thought I've had was to use a master-master configuration, but am unsure about the implementation of such a setup. Thoughts?

• matlab fit exp2

  - by HelloWorld

  I'm unsuccessfully looking for documentation of fit function using exp2 (sum of 2 exponents). How to operate the function is clear: [curve, gof] = fit(x, y,'exp2'); But since there are multiple ways to fit a sum of exponents I'm trying to find out what algorithm is used. Particularly what happens when I'm fitting one exponent (the raw data) with a bit of noise, how the exponents are spread. I've simulated several cases, and it seems that it "drops" all the weight on the second set of coefficients, but row data analysis often shows different behavior. Does anyone have suggestions of documentation?

• What's the purpose of the lua "stub" dll for windows.

  - by Roddy

  I'm looking at incorporating Lua into a C++ project, and am a bit confused by the presence of the two binaries (lua51.dll and lua5.1.dll) in the distribution from Luabinaries. According to the docs... In Windows your library or application must be linked with a stub library. A stub library is a library with only the function declarations that will bind your DLL with the Lua DLL. Why? I've never needed stub DLLs before when linking with third-party DLLs?

• Use a push button to add a section in an InfoPath form?

  - by Alex

  I'm working on an InfoPath form that's going to be run with InfoPath Forms Services on a SharePoint server. For a number of reasons -- mostly so that the customer can update the form without involving an administrator -- this can't be a form containing .NET code. The form has a repeating group, and we have users who are a bit confused as to how to add and delete items from the repeating section. I've looked all over the Internets, but haven't been able to find a way to do this without adding a code project to the form. Is there any way to write a rule or do something else to make a button that adds an item to a repeating section?

• Semantic Fish-eye zoom on table cells in UIKit?

  - by niblha

  How would I go about implementing a table view that looks and works something as illustrated in the link below, with UIKit for the iPhone? http://img442.imageshack.us/img442/4177/uifisheyeview.png I was thinking of using UITableView, and was looking a bit at the UITableViewDelegate methods tableView:willDisplayCell:forRowAtIndexPath: tableView:heightForRowAtIndexPath: But it seems as the UITableView will modify the cell frames after these methods are called and just before the cells are drawn? Maybe skipping the UITableView and go straight for some subclassing of a UIScrollView would be a better approach? So my question is basically that I would just like some overall thought in what might be the best ways to use existing UIKit components to implement this type of table view.

• How to do a Postgresql subquery in select clause with join in from clause like SQL Server?

  - by Ricardo

  I am trying to write the following query on postgresql: select name, author_id, count(1), (select count(1) from names as n2 where n2.id = n1.id and t2.author_id = t1.author_id ) from names as n1 group by name, author_id This would certainly work on Microsft SQL Server but it does not at all on postegresql. I read its documentation a bit and it seems I could rewrite it as: select name, author_id, count(1), total from names as n1, (select count(1) as total from names as n2 where n2.id = n1.id and n2.author_id = t1.author_id ) as total group by name, author_id But that returns the following error on postegresql: "subquery in FROM cannot refer to other relations of same query level". So I'm stuck. Does anyone know how I can achieve that? Thanks

• Enhanced Podcasts and MPMoviePlayerViewController

  - by Ben Robinson

  Hi, This is a bit of an odd/specific one - possibly a bug? I'm using MPMoviePlayerViewController to play a variety of files, including Enhanced Podcasts - these are audio files, but with a slideshow of images, often created using GarageBand. Until (i think) iOS 3.2 they weren't supported at all, now they are and play fine in the iPod app, but in my app the slideshow doesn't start, the full screen movie player opens, and the audio begins, but all I see is the QuickTime logo. If I scrub the track the pictures appear - and will continue to play correctly - but I see nothing if I don't scrub! Any ideas?? On a related note, these files also include a small rectangluar button containing an (i) button on the right hand side - anybody know what it is or should do?! It does nothing for me!

• GIS: When and why to use ArcObjects over GDAL programming to work with ArcGIS rasters and vectors?

  - by anotherobject

  Im just starting off with GDAL + python to support operations that cannot be done with ArcGIS python geoprocessing scripting. Mainly I am doing spatial modeling/analysis/editing of raster and vector data. I am a bit confused when ArcObject development is required versus when GDAL can be used? Is there functionality of ArcObjects that GDAL does not do? Is the opposite true too? I am assuming that ArcObjects are more useful in developing online tools versus Desktop analysis and modeling where the difference is more to do with preference? In my case i prefer GDAL because of python support, which I believe ArcObjects lack. thanks!

• Why will this code compile using ifort compiler and not when using gfortran compiler? Help!

  - by CuriousCompiler

  I'm rewriting some code to make a program compile with the gfortran compiler as opposed to ifort compiler I usually use. The code follows: _Subroutine SlideBits (WORD, BITS, ADDR) Implicit None Integer(4) WORD Integer(4) BITS Integer(4) ADDR Integer(4) ADDR1 ADDR1 = 32 - ADDR WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) End_ When I compile the above code using the gfortran compiler, I recieve this error: WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) Error: Operand of .NOT. operator at (1) is INTEGER(4) All three of the variables coming into the subroutine are integers. I've looked around a bit and the gfortran wiki states that the gfortran compiler should be able to handle logical statments being applied to integer values. Several other sites I've visited either quote from the gnu wiki or agree with it. This is the first time I've seen this error as the Intel Fortran compiler (ifort) I normally use compiles cleanly.

• How to Programmatically Identify a PI Font (a Dingbat) under OS X

  - by Glenn Howes

  There is a class of fonts called Pi fonts whose glyphs, under OS X, get mapped to the private Unicode space 0xF021-0xF0FF such that if you subtract 0xF000 from each unicode character to retrieve the 8-bit version of the character and be able to draw that character as if it were a standard Roman character. My question is how do I recognize these fonts? It's obvious the system can do so because there is a category on the Special Characters palette called "Pi Fonts" which apparently has the various such fonts installed on my system. In my case they are BookshelSymbolSeven, MSReferenceSpeciality, MT-Extras, Marlett, MonotypeSorts, Webdings, and various Wingdings. If I use the old fashioned QuickDraw routines to ask for the TextEncoding of these fonts, I get a value of 0x20000 which I do not see in the system header file TextCommon.h. Am I supposed to treat any font with a TextEncoding of 0x20000 as a Pi Font? And I'd rather not use any QuickDraw font handling routines for obvious reasons.

• Adding to a multidimensional array in PHP

  - by b. e. hollenbeck

  I have an array being returned from the database that looks like so: $data = array(201 => array('description' => blah, 'hours' => 0), 222 => array('description' => feh, 'hours' => 0); In the next bit of code, I'm using a foreach and checking the for the key in another table. If the next query returns data, I want to update the 'hours' value in that key's array with a new hours value: foreach ($data as $row => $value){ $query = $db->query($sql); if ($result){ $value['hours'] = $result['hours']; } I've tried just about every combination of declarations for the foreach loop, but I keep getting the error that it's a non-object. Surely this is easier than my brain is perceiving it.

• Encrypt text using a number

  - by Adam Matan

  Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

• 2008 Datacenter Word Automation issue

  - by Brad

  We have an application that uses word automation. It works fine under Windows XP, but does not work on our Windows Server 2008 64-bit virtual machine running on VMware ESX unless it is running as the domain administrator. Under any other account (including a local admin), Word starts, uses a lot of CPU for 40 seconds when opening a document, and then just hangs. Our application does not access anything not on the local machine, and this machine is not being used for anything else (not a domain controller, etc). I know others have posted similar issues, with the solution of creating a Desktop folder somewhere under the windows directory. We did this, and it did not solve the problem (Word did not get as far as it did before we did this though). Please don't turn this into a thread about why I am trying to do this, whether I should do this, or whether I need to. For argument sake, I don't need to do this, but understanding what privilege a local admin does not have that is needed to do this is a legitimate concern.

• How do I configure the Python logging module in Django?

  - by mipadi

  I'm trying to configure logging for a Django app using the Python logging module. I have placed the following bit of configuration code in my Django project's settings.py file: import logging import logging.handlers import os date_fmt = '%m/%d/%Y %H:%M:%S' log_formatter = logging.Formatter(u'[%(asctime)s] %(levelname)-7s: %(message)s (%(filename)s:%(lineno)d)', datefmt=date_fmt) log_dir = os.path.join(PROJECT_DIR, "var", "log", "my_app") log_name = os.path.join(log_dir, "nyrb.log") bytes = 1024 * 1024 # 1 MB if not os.path.exists(log_dir): os.makedirs(log_dir) handler = logging.handlers.RotatingFileHandler(log_name, maxBytes=bytes, backupCount=7) handler.setFormatter(log_formatter) handler.setLevel(logging.DEBUG) logging.getLogger().setLevel(logging.DEBUG) logging.getLogger().addHandler(handler) logging.getLogger(__name__).info("Initialized logging subsystem") At startup, I get a couple Django-related messages, as well as the "Initialized logging subsystem", in the log files, but then all the log messages end up going to the web server logs (/var/log/apache2/error.log, since I'm using Apache), and use the standard log format (not the formatter I designated). Am I configuring logging incorrectly?

• where does the professional sheen of a GUI application realistically come from?

  - by JW

  I have been playing around with php-gtk recently and in the past I have experimented with Java to make GUI 'hello world' apps. However both these types of applications have had a bit of a clunky (almost childish) look and feel to them. I cannot deny that they are handy for making apps for in-house use (and I totally respect the amount of community effort that goes into these projects). But I would not necessarily be proud to sell it as a commercial application with a price tag of, say, £450 or £1,000. If I wanted to make an application that had the look and feel of, say, Firefox for Windows, or Adobe xyz, what GUI/language should I use? Is the 'professional sheen' or smart look and feel down to the designer or is it the case that, no matter how good a designer is, picking the right GUI framework is essential to get that look?

• Linux program in FreeBSD

What can I do? Can I build the program for FreeBSD on my Ubuntu computer by changing some build options, or I need to build it in FreeBSD OS? Maybe there is some way to convert executable to format recognized by FreeBSD?

• Is there an easy way of obtaining the total page response time in ASP.Net?

  - by Earlz

  Hello, commonly on say PHP or other web frameworks getting the total response time is easy, just start the timer at the top of the file and stop it at the end. In ASP.Net there is the whole Page Lifecycle bit though so I'm not sure how to do this. I would like for this response time recording to take place in a master page and the response time show up in the footer of pages. What would be the best way of doing this? Is there something built in to ASP.Net for it? Is it even possible to include the OnRender time?

• Saving highscores coupled to a facebook account

  - by Eiko

  I want to offer a "highscore" list for friends in my app (at this point iPhone/iPad), so that if the user connected to facebook, he will get a list with his/her friends scores. Connecting is easy, retrieving friends is easy, but figuring out the best way to store the scores is not. As it seems I need to the store the scores on my own server server, no big deal. But what is considered a reasonable safe way to transfer the data? When communicating with facebook, authentication is clear - but communicating with my server basically anyone could post scores for another user if I send user id and score. Obfuscation might help a bit, but is there any better way to make sure that the data comes from the fb-logged-in person? Scores can also go down, so changing scores for other persons won't necessary help them. Thanks :)

• What CPAN module can summarize Perl error logs?

  - by mithaldu

  I'm maintaining some website code that will soon dump all its errors and warnings into a log file. In order to make this a bit more pro-active I plan to parse this log file daily, summarize the warnings and errors (i.e. count the occurrence of each specific one and group by either warning/error) and then email this to the devs on the project. This would likely admittedly be rather trivial with a hash and some further fiddling, I wondered if there is a suitable module on CPAN that I could use to do this task. It would either be one that summarizes specifically Perl error/warnings logs or one that summarizes arbitrary text files. Any suggestions?

• click-event doesn't fire if blur changes layout

  - by rag

  I have a form with blur-events bound to the required fields. Then there is a "Cancel" Button which simply calls an URL (button is an image with click-event). When leaving one of the required fields a warning is written to the page saying that field xy is required. - this causes a layout shift, meaning all the fields and the buttons are moved down a little bit because of the text inserted above. The tricky thing is this: when the focus is in an empty but required field and you click the cancel button, the required-warning is written to the screen but the click-event on the cancel button doesn't fire. I think this is due to the layout shift. The mouse cursor doesn't hover over the button anymore, because the button scrolled down. Has anyone a good idea how i could solve this?

• Kohana Database Library - How to Execute a Query with the Same Parameters More Than Once?

  - by Noah Goodrich

  With the following bit of code: $builder = ORM::factory('branch')->where('institution_id', $this->institution->id)->orderby('name'); I need to first execute: $count = $builder->count_all(); Then I need to execute: $rs = $builder->find_all($limit, $offset); However, it appears that when I execute the first query the stored query parameters are cleared so that a fresh query can be executed. Is there a way to avoid having the parameters cleared or at least copy them easily without having to reach directly into the Database driver object that stores the query parameters and copy them out? We are using Kohana 2.3.4 and upgrading is not an option.
