  • Thread Proc for an instancable class?

    - by user146780
    Basically I have a class and it is instincable (not static). Basically I want the class to be able to generate its own threads and manage its own stuff. I don't want to make a global callback for each instance I make, this doesnt seem clean and proper to me. What is the proper way of doing what I want. If I try to pass the threadproc to CreateThread and it is the proc from a class instance the compiler says I cannot do this. What is the best way of achieving what I want? Thanks

  • T-SQL: Dynamic Where clause in normal SQL statement

    - by Torben H.
    Hey there, I looking for a way to dynamicly add a filter to my statment without using dynamic SQL. I want to select all computers from a table, but when I pass a computer id to the sp, I want to get only this computer. Actually I try this on DECLARE @ComputerFilter AS INT DECLARE @ComputerID AS INT SELECT Computername FROM Computer WHERE (ComputerID = @ComputerID) OR (@ComputerFilter IS NULL)) But this is 100 times slow then this statment and tooks as long as SELECT * FROM Computer SELECT Computername FROM Computer WHERE ComputerID = @ComputerID Is there a way to speed this statment up or is there any other way to solve this problem with one select und without dynamic sql?

  • cakephp - try/catch an Action

    - by joshs
    I would like to somehow apply a try catch statement to all Actions as a backstop for any uncaught exceptions. I think this would be particularly helpful for Ajax Actions, because the catch statement could send back a default 4xx status code. Prototype's onFailure() function could then do the client-side error handling. How can I do this without wrapping the Action call with a try/catch in the cake dispatcher like this: try { output = $controller->dispatchMethod($params['action'], $params['pass']); } catch {...} Does anybody have a suggestion or another workable strategy for gaining this functionality without touching the dispatcher? How do people feel about putting exception handling in the Displatcher? I imagine when cake drops php 4 support, there will be a built-in mechanism for this.

  • Python Introspection: How to get varnames of class methods?

    - by daccle
    I want to get the names of the keyword arguments of the methods of a class. I think I understood how to get the names of the methods and how to get the variable names of a specific method, but I don't get how to combine these: class A(object): def A1(self, test1=None): self.test1 = test1 def A2(self, test2=None): self.test2 = test2 def A3(self): pass def A4(self, test4=None, test5=None): self.test4 = test4 self.test5 = test5 a = A() # to get the names of the methods: for methodname in a.__class__.__dict__.keys(): print methodname # to get the variable names of a specific method: for varname in a.A1.__func__.__code__.co_varnames: print varname # I want to have something like this: for function in class: print function.name for varname in function: print varname # desired output: A1 self test1 A2 self test2 A3 self A4 self test4 test5

  • Create mp3 previews from wav and aiff files

    - by August Lilleaas
    I would like to create a program that makes mp3s of the first 30 seconds of an aiff or wav file. I would also like to be able to choose location and length, such as the audio between 2:12 and 2:42. Are there any tools that lets me do this? Shelling out is OK. The application will run on a linux server, so it would have to be a tool that works on linux. I don't mind doing it in two steps - i.e. a tool that first creates the cutout of the aiff/wav, then pass it to a mp3 encoder.

    This error is driving me nuts!!! Caused by: java.lang.NoSuchMethodException: com.mksoft.fbautomate.domain.Account$Type.values() The same exact class works fine in a separate Groovy file.

  • Types in Python - Google Appengine

    - by Chris M
    Getting a bit peeved now; I have a model and a class thats just storing a get request in the database; basic tracking. class SearchRec(db.Model): WebSite = db.StringProperty()#required=True WebPage = db.StringProperty() CountryNM = db.StringProperty() PrefMailing = db.BooleanProperty() DateStamp = db.DateTimeProperty(auto_now_add=True) IP = db.StringProperty() class AddSearch(webapp.RequestHandler): def get(self): searchRec = SearchRec() searchRec.WebSite = self.request.get('WEBSITE') searchRec.WebPage = self.request.get('WEBPAGE') searchRec.CountryNM = self.request.get('COUNTRY') searchRec.PrefMailing = bool(self.request.get('MAIL')) searchRec.IP = self.request.get('IP') Bool has my biscuit; I thought that setting bool(self.reque....) would set the type of the string but no matter what I pass it it still stores it as TRUE in the database. I had the same issue with using required=True on strings for the model; the damn thing kept saying that nothing was being passed... but it had. Ta

  • Variadic functions and arguments assignment in C/C++

    - by Rizo
    I was wondering if in C/C++ language it is possible to pass arguments to function in key-value form. For example in python you can do: def some_function(arg0 = "default_value", arg1): # (...) value1 = "passed_value" some_function(arg1 = value1) So the alternative code in C could look like this: void some_function(char *arg0 = "default_value", char *arg1) { ; } int main() { char *value1 = "passed_value"; some_function(arg1 = value1); return(0); } So the arguments to use in some_function would be: arg0 = "default_value" arg1 = "passed_value" Any ideas?

  • adhoc struct/class in C#?

    - by acidzombie24
    Currently i am using reflection with sql. I find if i want to make a specialize query it is easiest to get the results by creating a new class inheriting from another and adding the 2 members/columns for my specialized query. Then due to reflections in the lib in my c# code i can write foreach(var v in list) { v.AnyMember and v.MyExtraMember) Now instead of having the class scattered around or modifying my main DB.cs file can i define a class inside a function? I know i can create an anonymous object by writing new {name=val, name2=...}; but i need a to pass this class in a generic function func(query, args);

  • How to click through JGlassPane With MouseListener to UI behind it

    - by Epicmaster
    I have a JFrame and a bunch of JComponents on top of the JFrame. I need to make use of the JGlassPane and I used this implementation to set it up. JPanel glass = new JPanel(); frame.setGlassPane(glass); glass.setVisible(true); glass.setOpaque(false); After doing so I can't select any JButtons or other JComponents under the JGlassPane. Is there a way to have only the components on the GlassPane selectable while still having the ability to select components under the GlassPane? Edit I forgot to mention (not knowing this would be relevant) that I did attach both a MouseListener and a MouseMotionListener to the glass pane. Is there a way to pass the Mouse Events to other components and only use them when needed?

  • Multi-part template issue with Jinja2

    - by Alan Harris-Reid
    Hi, When creating templates I typically have 3 separate parts (header, body, footer) which I combine to pass a singe string to the web-server (CherryPy in this case). My first approach is as follows... from jinja2 import Environment, FileSystemLoader env = Environment(loader=FileSystemLoader('')) tmpl = env.get_template('Body.html') page_body = tmpl.render() tmpl = env.get_template('Header.html') page_header = tmpl.render() tmpl = env.get_template('Footer.html') page_footer = tmpl.render() page_code = page_header + page_body + page_footer but this contains repetitious code, so my next approach is... def render_template(html_file): from jinja2 import Environment, FileSystemLoader env = Environment(loader=FileSystemLoader('')) tmpl = env.get_template(html_file) return tmpl.render() page_header = render_template('Header.html') page_body = render_template('Body.html') page_footer = render_template('Footer.html) However, this means that each part is created in its own environment - can that be a problem? Are there any other downsides to this approach? I have chosen the 3-part approach over the child-template approach because I think it may be more flexible (and easier to follow), but I might be wrong. Anyone like to convince me that using header, body and footer blocks might be better? Any advice would be appreciated. Alan

  • WPF passing the Int argument to a data object provider method

    - by SAD
    Hi, I'm trying to produce a master/detail datagrid view. I'm using object data providers. Now I have seen many examples when the argument of a method for returning the records for the detail view is a string, like in this example: <!-- the orders datasource --> <ObjectDataProvider x:Key="OrdersDataProvider" ObjectType="{x:Type local:OrdersDataProvider}"/> <ObjectDataProvider x:Key="Orders" MethodName="GetOrdersByCustomer" ObjectInstance="{StaticResource OrdersDataProvider}" > <ObjectDataProvider.MethodParameters> <x:Static Member="system:String.Empty"/> </ObjectDataProvider.MethodParameters> </ObjectDataProvider> But in my case, the argument that I want to pass is the int ID not the string. Can I still somehow use the object data provider to return all the records from the database for the detail view if the argument passed to a method has to be an int? How could it be implemented in MVVM? Thanks a lot for any advice1

  • Communication between java server and matlab client

    - by user272587
    I'd like to establish a server(Java)/client (Matlab) communication using socket. They can send messages to each other. An example shows how to do this in Java server and Java client, http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html. When I try to rewrite the client part in Matlab, I only can get the first message that the Java server sends and display it in the Matlab command window. When I type a message in the Matlab command window, I can't pass it to the Java Server. Jave code: kkSocket = new Socket("localhost", 3434); Matlab equivalent: kkSocket = Socket('localhost', 3434); Java code for client: out = new PrintWriter(kkSocket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader(kkSocket.getInputStream())); What would be a Matlab equivalent for this? Thanks in advance.

  • How can Perl interact with an ajax form

    - by Jeff
    I'm writing a perl program that was doing a simple get command to retrieve results and process them. But the site has been updated and now has a java component that handles the results (so the actual data is not in the source code anymore). This is the site: http://wro.westchesterclerk.com/legalsearch.aspx Try putting in: Index Number: 11103 Year: 2009 I want to be able to pro grammatically enter the "index number" and "year" at the bottom of the form where it says "search by number" and then retrieve the results listed next to it. I've written many programs in Perl that simply pass variables via the URL and the results are listed in the source code, so it's easy to parse. (Using LWP:Simple) Like: $html = get("http://www.url.com?id=$somenum&year=$someyear") But this is totally new to me and I don't know where to begin. I'm somewhat familiar with LWP:UserAgent and Mechanize. I'd really appreciate any help. Thanks!

  • Iterating backward

    - by MBennett
    Suppose I have a vector<int> myvec and I want to loop through all of the elements in reverse. I can think of a few ways of doing this: for (vector<int>::iterator it = myvec.end() - 1; it >= myvec.begin(); --it) { // do stuff here } for (vector<int>::reverse_iterator rit = myvec.rbegin(); rit != myvec.rend(); ++rit) { // do stuff here } for (int i = myvec.size() - 1; i >= 0; --i) { // do stuff here } So my question is when should I use each? Is there a difference? I know that the first one is dangerous because if I pass in an empty vector, then myvec.end() - 1 is undefined, but are there any other hazards or inefficiencies with this?

  • Writing a search engine

    - by wvd
    Hello all, The title might be a bit misleading, but I couldn't figure out a better title. I'm writing a simple search engine which will search on several sites for the specific domain. To be concrete: I'm writing a search engine for hardstyle livesets/aftermovies/tracks. To do I will search on the sites who provide livesets, tracks, and such. The problem here is speed, I need to pass the search query to 5-7 sites, get the results and then use my own algorithm to display the results in a sorted order. I could just "multithread" it, but it's easier said then done so I have a few questions. What would be the best solution to this problem? Should I just multithread/process this application, so I'm going to get a bit of speed-up? Are there any other solutions or I am doing something really wrong? Thanks, William van Doorn

  • TypeError: Python thinks that I passed a function 2 arguments but I only passed it 1

    - by slhck
    I work on something in Seattle Repy which is a restricted subset of Python. Anyway, I wanted to implement my own Queue that derives from a list: class Queue(list): job_count = 0 def __init__(self): list.__init__(self) def appendleft(item): item.creation_time = getruntime() item.current_count = self.job_count self.insert(0, item) def pop(): item = self.pop() item.pop_time = getruntime() return item Now I call this in my main server, where I use my own Job class to pass Jobs to the Queue: mycontext['queue'] = Queue() # ... job = Job(str(ip), message) mycontext['queue'].appendleft(job) The last line raises the following exception: Exception (with type 'exceptions.TypeError'): appendleft() takes exactly 1 argument (2 given) I'm relatively new to Python, so could anyone explain to me why it would think that I gave appendleft() two arguments when there obviously was only one?

  • How to assign permissions for Copy/Paste on windows

    - by jalchr
    Well, as everyone knows there is no way you can assign permissions for Copy/Paste of files on windows platform. I need to control the copy process from a central file server, in a way that helps me know: which user performed the copy Which files were copied where did he pasted them Total size of data copied Time of copy operation If user exceeds the allowed "Copy-Limit", a dialog box requests him to enter administrative credentials or deny him (as it would be configured) Store all this data in a file for later review or send by email. I need to collect this data by putting a utility program on the server itself, without any other installation on client computers. I know about monitoring the Clipboard, but which clipboard would it be? the user's clipboard or the server's clipboard ? And what about drag-drop operation, which doesn't even pass through the clipboard? Any knowledge of whether SystemFileWatcher is useful in such case ? Any ideas ?

  • Loading an OverlayView from XIB -vs- programmatically for use with UIImagePickerController

    - by PLG
    I am currently making a camera app for iPhone and I have a strange phenomenon that I can't figure out. I would appreciate some help understanding. When recreating an overlay view for passing to UIImagePickerController, I have been successfully been able to create the view programmatically. What I haven't been able to do is create the view with/without controller in IB, load it and pass it to the overlay pointer successfully. If I do it via IB, the view is not opaque and obscures the view of the camera completely. I can not figure out why. I was thinking that the normal view pointer might be assigned when loading from XIB and therefore overwrite the camera's view, but I have an example programmatically where view and overlayView are set equal in the controller class. Perhaps the load order is overwriting a pointer? Help would be appreciated... kind regards.

  • C - how to get fscanf() to determine whether what it read is only digits, and no characters

    - by hatorade
    Imagine I have a csv with and each value is an integer. so the first value is the INTEGER 100. I want fscanf() to read this line, and either tell me it's an integer ONLY, or not. So, it would pass 100 but fail on 100t. What i've been trying to get work is "%d," where the comma is the delimiter of my CSV. so the whole function is fscanf(fp, "%d,", &count) Unfortunately, this fails to fail on '100t,' works on '100' and works on 't'. so it just isn't distinguishing between 100 and 100t (all of these numbers are followed by commas, of course

  • Linq to SQL Where clause based on field selected at runtime

    - by robasaurus
    I'm trying to create a simple reusable search using LINQ to SQL. I pass in a list of words entered in a search box. The results are then filtered based on this criteria. private IQueryable<User> BasicNameSearch(IQueryable<User> usersToSearch, ICollection<string> individualWordsFromSearch) { return usersToSearch .Where(user => individualWordsFromSearch.Contains(user.Forename.ToLower()) || individualWordsFromSearch.Contains(user.Surname.ToLower())); } Now I want this same search functionality on a different datasource and want to dynamically select the fields to apply the search to. For instance instead of IQueryable of Users I may have an IQueryable of Cars and instead of firstname and surname the search goes off Make and Model. Basically the goal is to reuse the search logic by dynamically selecting what to search on at runtime.

  • Sphinx non-fulltext, integer only search

    - by James
    Hello guys, I've got a few tables that literally only hold integers, no "words" and for some reason Sphinx is unable to hold this data in it's library.

Below is an example from my Sphinx.conf for one that fails. source track { type = mysql sql_host = host sql_user = user sql_pass = pass sql_db = db sql_port = port sql_query = SELECT id, user, time FROM track; sql_attr_uint = user sql_attr_uint = time sql_query_info = SELECT * FROM track WHERE id=$id } index track { source = track path = /var/lib/sphinx/track docinfo = extern charset_type = utf-8 min_prefix_len = 1 enable_star = 1 }
