  • python win32 simulate click

    - by nabizan
    Let's say I've got a window for which I want to simulate a mouse click at a specific x, y coordinate. I already have the hwnd but I'm not sure how to construct the lParam. I've used SendMessage in the past to click on buttons, etc., but I knew their hwnds. Any help would be greatly appreciated. I also can't help but wonder if I'm going about this the right way. My end goal is clicking on a certain user on skype main window (for example). I used EnumChildWindows to find all the main window's children, but couldn't find the right one. So figured I would try to 'click' on it using coordinates.

  • add extra data to response object to render in template

    - by mp0int
    I ned to write a code sniplet that enables to disable connection to some parts of a site. Admin and the mainpage will be displayable, but user section (which uses ajax) will be displayed, but can not be used (vith a transparent div set over the page). Also there is a few pages which will be disabled. my logic is that, i write a middleware, def process_request(self, request): if ayar.tonline_kapali: url_parcalari = request.path.split('/') if url_parcalari[0] not in settings.BAGIMSIZ_URLLER: if not request.is_ajax(): return render_to_response('bakim_modu.html') else: return None that code let me to display a "site closed" message for the urls not in BAGIMSIZ_URLLER (which contains urls that will be accessible) But i do not figure out how can i solve the problem about ajax pages... i need to set a header or something to the response and need to check it in the template.

  • What advantages can I get from learning C++ if I'm mainly a C# Programmer?

    - by Sergio Tapia
    Hello, Recently I've started to notice a lot of smirks and generally rude comments whenever I mention C#. Everyone I talk to either says learn Python or learn C++. Python is a nice language, I get it. But I don't find much use for it right now (for my use cases), and C++ I heard is a faster language (not sure). So my question is this, what advantage can I get from learning C++ (besides the knowledge and expansion of my horizons), when I mainly program in C#. If anyone can make a legitimate claim, I'll for sure look into learning the language because let's face it, I trust you guys. Thanks so much for all the help.

  • App Engine: how would you... snapshotting entities

    - by Andrew B.
    Let's say you have two kinds, Message and Contact, related by a db.ListProperty of keys on Message. A user creates a message, adds some contacts as recipients, and emails the message. Later, the user deletes one of the contact entities that was a recipient of the message. Our application should delete the appropriate Contact entity, but we want to preserve the original recipient list for the message that was sent for the user's records. In essence, we want a snapshot of the message entity at the time it was sent. If we naively delete the contact entity, though, we lose snapshot integrity; if not, we are left with an invalid key. How would you handle this situation, either in controller logic or model changes? class User(db.Model): email = db.EmailProperty(required=True) class Contact(db.Model): email = db.EmailProperty(required=True) user = db.ReferenceProperty(User, collection_name='contacts') class Message(db.Model): recipients = db.ListProperty(db.Key) # contacts sender = db.ReferenceProperty(User, collection_name='messages') body = db.TextProperty() is_emailed = db.BooleanProperty(default=False)

  • Java long task - Did it stop writing to file?

    - by rockit
    I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

  • Type-aware rendering (and editing) of tabular data in pyqt4

    - by pihentagy
    I would like to have a very short / minimal example of how to create some tabular widget with different types of item in it. In the first round let's say I'd like to render [["Hello", 12, True], ["World", 13, False]] (Hello as string, 12 as number (right-align), True as a checkbox for eg.), but it would be nice to have Dates, Colors, and other type of info. Next round: editing (integer with spinbox, maybe sometimes a combobox is handy, but that may not work out of the box). There must be a simple solution, but I couldn't find...

  • Entity Framework projections

    - by David McClelland
    We are investigating the Entity Framework to see if it will meet our particular needs. Here is the scenario I am interested in: I have a large table (let's call it VeryWideRecord) which has many columns, and it has a corresponding business object (it's also called VeryWideRecord). I would like to be able to query my database for a VeryWideRecord business object, but only have values for certain columns returned by the underlying SQL. Can I do this with the Entity Framework? I am uncertain as to whether this could be done with the Entity Framework's table splitting feature, because the application needs to be able (at runtime) to change the columns that are requested. The reason for this is that we are trying to minimize the amount of information that is going across the wire. I see how this could be done using NHibernate (example), but how can I do this with the Entity Framework?

  • PHP: find 2 or more numbers from a list of N numbers that can add up towards a given ammount

    - by Splash
    Hi Guys, I am trying to create a little php script that can make my life a bit easier. Basically, I am going to have 21 text fields on a page where I am going to input 20 different numbers. In the last field I will enter a number let's call it the TOTAL AMMOUNT. All I want the script to do is to point out which numbers from the 20 fields added up will come up to TOTAL AMMOUNT. Example: field1= 25.23 field2= 34.45 field3= 56.67 field4= 63.54 field5= 87.54 .... field20= 4.2 Total Ammount= 81.90 Output: field1+fields3=81.90 Some of the fields might have 0 as value because sometimes I only need to enter 5-15 fields and the maximum will be 20. If someone can help me out with the php code for this, will be greatly appreciated.

  • Problem with number/type of arguments passed to an overloaded c++ constructor wrapped with swig.

    - by MiKo
    I am trying to wrap a c++ class (let's call it "Spam") written by someone else with swig to expose it to Python. After solving several problems, I am able to import the module in python, but when I try to create an object of such class I obtain the following error: foo = Spam.Spam('abc',3) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "Spam.py", line 96, in __init__ this = _Spam.new_Spam(*args) NotImplementedError: Wrong number of arguments for overloaded function 'new_Spam'. Possible C/C++ prototypes are: Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action,char const *) Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action) Spam(unsigned char *,unsigned long,bool,unsigned int) Spam(unsigned char *,unsigned long,bool) Spam(unsigned char *,unsigned long) Googling around, I realized that the error is probably caused by the type of the arguments and not by the number (which is quite confusing), but I still cannot identify. I suspect the problem lies in passing a string as the first argument, but have no idea on how to fix it (keep in mind that I know almost no c/c++).

  • How to raise CComponent event in Yii

    - by srigi
    Let's assume I have Component (say Graph like Yahoo Finance) rendered on the page. Component view template contains bunch of a_hrefs which I wanto to switch period in graph. I created Event and Event handler in Component. I have two questions: How to raise event on Graph Component via those a_hrefs (should they be part of Graph?)? How to redraw Graph without loosing curent page context (section, filter - specified as $_GET values)? My Graph Component look like this: Yii::import('zii.widgets.CPortlet'); class Graph extends CPortlet { private $_period; /* ********************** * * COMPONENT PROPERTIES * * ********************** */ public function getPeriod() { return $this-_period; } public function setPeriod($period) { $this-_period = $period; } /* ********************** * * GENERIC * * ********************** */ public function init() { parent::init(); // assign event handlers $this-onPeriodChange = array($this, 'handlePeriodChange'); } protected function renderContent() { $this-render('graph'); } /* ********************** * * EVENTS * * ********************** */ public function onPeriodChange($event) { $this-raiseEvent('onPeriodChange', $event); } /* ********************** * * EVENT HANDLERS * * ********************** */ public function handlePeriodChange($event) { // CODE } }

  • Django: where do I call settings.configure?

    - by RexE
    The Django docs say that I can call settings.configure instead of having a DJANGO_SETTINGS_MODULE. I would like my website's project to do this. In what file should I put the call to settings.configure so that my settings will get configured at the right time? Edit in response to Daniel Roseman's comment: The reason I want to do this is that settings.configure lets you pass in the settings variables as a kwargs dict, e.g. {'INSTALLED_APPS': ..., 'TEMPLATE_DIRS': ..., ...}. This would allow my app's users to specify their settings in a dict, then pass that dict to a function in my app that augments it with certain settings necessary to make my app work, e.g. adding entries to INSTALLED_APPS. What I envision looks like this. Let's call my app "rexe_app". In wsgi.py, my app's users would do: import rexe_app my_settings = {'INSTALLED_APPS': ('a','b'), ...} updated_settings = rexe_app.augment_settings(my_settings) # now updated_settings is {'INSTALLED_APPS': ('a','b','c'), 'SESSION_SAVE_EVERY_REQUEST': True, ...} settings.configure(**updated_settings)

  • Lazy loading? Better avoiding it?

    - by Charlie Pigarelli
    I just read about this design pattern: Lazy Load. And, since in the application i'm working on i have all the classes in one folder, i was wondering if this pattern could just make me avoiding the include() function for every class. I mean: It's nice to know that if i forgot to include a class, PHP, before falling into an error, trough an __autoload() function try to get it. But is it fine enough to just don't care about including classes and let PHP do it by your own every time? Or we should write __autoload() just in case it is needed?

  • Understanding Clojure concurrency example

    - by dusha
    Hello, I just go through various documentation on Clojure concurrency and came accross the example on the website (http://clojure.org/concurrent_programming). (import '(java.util.concurrent Executors)) (defn test-stm [nitems nthreads niters] (let [refs (map ref (replicate nitems 0)) pool (Executors/newFixedThreadPool nthreads) tasks (map (fn [t] (fn [] (dotimes [n niters] (dosync (doseq [r refs] (alter r + 1 t)))))) (range nthreads))] (doseq [future (.invokeAll pool tasks)] (.get future)) (.shutdown pool) (map deref refs))) I understand what it does and how it works, but I don't get why the second anonymous function fn[] is needed? Many thanks, dusha. P.S. Without this second fn [] I get NullPointerException.

  • How do I do a semijoin using SQLAlchemy?

    - by Jason Baker
    http://en.wikipedia.org/wiki/Relational_algebra#Semijoin Let's say that I have two tables: A and B. I want to make a query that would work similarly to the following SQL statement using the SQLAlchemy orm: SELECT A.* FROM A, B WHERE A.id = B.id AND B.type = 'some type'; The thing is that I'm trying to separate out A and B's logic into different places. So I'd like to make two queries that I can define in separate places: one where A uses B as a subquery, but only returns rows from A. I'm sure this is fairly easy to do, but an example would be nice if someone could show me.

  • How to get rid of library references problem? Java

    - by Nitesh Panchal
    Hello, I created a web application and it used several libraries once upon a time. So i added them but later on i found alternative and actually better ways to do the same things. So i removed references from my project for those jars and libraries. Everything works fine but when i move the same project to my friend's laptop Netbeans 6.8 simply doesn't let me deploy the project and gives the whole bundle of errors of libraries that i used previously but i don't now. I removed all references from build.impl file and then when i deploy it, it works fine. But when i do a clean and build and try to deploy it, build.impl automatically again adds those lines of xml which contain references to libraries an again gives me a whole long list of errors. How do i get rid of this? I am really tired of these silly errors. Thanks in advance :)

  • is putting N in front of strings in scripts considered a "best practice"?

    - by jcollum
    Let's say I have a table that has a varchar field. If I do an insert like this: INSERT MyTable SELECT N'the string goes here' Is there any fundamental difference between that and: INSERT MyTable SELECT 'the string goes here' My understanding was that you'd only have a problem if the string contained a Unicode character and the target column wasn't unicode. Other than that, SQL deals with it just fine and converts the string with the N'' into a varchar field (basically ignores the N). I was under the impression that N in front of strings was a good practice, but I'm unable to find any discussion of it that I'd consider definitive. Title may need improvement, feel free.

  • Assorted list of what's new in Delphi [Language, RTL, VCL]?

    - by utku_karatas
    Hi gents, As someone who's been stuck at the older versions of Delphi and upgraded to D2010 lately, I figure I still use the language, RTL and VCL features from the D5 era and refrain from using these new features as the documents on those are somewhat decentralized around the blogosphere. So I'd like to ask if there was an assorted list like what's new docs of Python's - clear and concise to the point. Btw, please no screencasts. They seem to be quite abundant lately (probably because of CodeRages) but I find them very unintuitive to learn from. Let's leave that docs in video format thing to RoR community, shall we :).

  • Customized generation/filtering resources with maven

    - by zamza
    I wonder what is the Maven way in my situation. My application has a bunch of configuration files, let's call them profiles. Each profile configuration file is a *.properties file, that contains keys/values and some comments on these keys/values semantics. The idea is to generate these *.properties to have unified comments in all of them. My plan is to create a template.properties file that contains something like #Comments for key1/value1 key1=${key1.value} #Comments for key2/value2 key2=${key2.value} and a bunch of files like #profile_data_1.properties key1.value=profile_1_key_1_value key2.value=profile_1_key_2_value #profile_data_2.properties key1.value=profile_2_key_1_value key2.value=profile_2_key_2_value Then bind to generate-resources phase to create a copy of template.properties per profile_data_*, and filter that copy with profile_data_*.properties as a filter. The easiest way is probably to create an ant build file and use antrun plugin. But that is not a Maven way, is it? Other option is to create a Maven plugin for that tiny task. Somehow, I don't like that idea (plugin deployment is not what I want very much).

    Hi all I have written a MVVM prototype as a learning exercise and I am struggling to understand how I can communicate between views.Let me explain I have a treeview on the left (leftSideView) ListView on the right (rightSideView) MainWindow (includes the 2 views mentioned above and a splitter) What I have implemented does not work and I would like you if you can point out where I am going wrong or if there is a better way of doing it. you can download the quick prototype from here http://cid-9db5ae91a2948485.skydrive.live.com/self.aspx/.Public/WpfCommunicationBetweenViews.zip For sure I am doing something wrong with the bindind. Also it would be nice to learn how you do it. EG ListBox on left (one view) ListView On the right (another view) how u communicate between the two. Thanks a lot of any suggestions

  • Python accessing modules from package that is distributed over different directories

    - by chaindriver
    Hi, I have a question regarding one single module that is distributed over multiple directories. Let's say I have these two file and directories: ~/lib/python xxx __init__.py util __init__.py module1.py module2.py ~/graphics/python xxx __init__.py misc __init__.py module3.py module4.py So then in my Python modules, I did this: import sys pythonlibpath = '~/lib/python' if pythonlibpath not in sys.path: sys.path.append(pythonlibpath) import xxx.util.module1 which works. Now, the problem is that I need xxx.misc.module3, so I did this: import sys graphicslibpath = '~/graphics/python' if graphicslibpath not in sys.path: sys.path.append(graphicslibpath) import xxx.misc.module3 but I get this error: ImportError: No module named misc.module3 It seems like it somehow still remembers that there was a xxx package in ~/lib/python and then tries to find misc.module3 from there. How do I get around this issue?

  • FastCGI, PHP, Sendmail, and Codeigniter

    - by Kyle J. Dye
    Hi Everyone. I am experiencing an odd issue. I just switched to FastCGI (Apache) because of the big performance boost. Everything is working great, except when I attempt to use sendmail (Codeigniter Class or just raw PHP). I have tested with and without CI and still get a 500 internal server error when trying to send. Could this be getting caused by a discrepency in how FastCGI utilizes sendmail? Has anyone else experienced this issue? Also, the email will send, it just errors afterwards. Please let me know a solution if you have one! Thanks! :)

  • Modifiers in Makefile rule's dependency list

    - by gnu_maker
    The problem is fairly simple. I am trying to write a rule, that given the name of the required file will be able to tailor its dependencies. Let's say I have two programs: calc_foo and calc_bar and they generate a file with output dependent on the parameter. My target would have a name 'target_*_*'; for example, 'target_foo_1' would be generated by running './calc_foo 1'. The question is, how to write a makefile that would generate outputs of the two programs for a range of parameters?

  • How to correctly do SQL UPDATE with weighted subselect?

    - by luminarious
    I am probably trying to accomplish too much in a single query, but have I an sqlite database with badly formatted recipes. This returns a sorted list of recipes with relevance added: SELECT *, sum(relevance) FROM ( SELECT *,1 AS relevance FROM recipes WHERE ingredients LIKE '%milk%' UNION ALL SELECT *,1 AS relevance FROM recipes WHERE ingredients LIKE '%flour%' UNION ALL SELECT *,1 AS relevance FROM recipes WHERE ingredients LIKE '%sugar%' ) results GROUP BY recipeID ORDER BY sum(relevance) DESC; But I'm now stuck with a special case where I need to write the relevance value to a field on the same row as the recipe. I figured something along these lines: UPDATE recipes SET relevance=(SELECT sum(relevance) ...) But I have not been able to get this working yet. I will keep trying, but meanwhile please let me know how you would approach this?
