  • Is the Sleep operation no longer used in VBscript?

    - by Cheesus Toast
    The "Sleep" command as stated in many places over the internet (including here on this forum) DOES NOT WORK. Is it now an obsolete command? I am writing the VBScript code like this: sub button1_onclick() Wscript.Sleep 1000 div1.innerHTML = textbox1.value end sub It should wait 1 second and then execute that simple command. This is an utterly simple statement but it does not work. Plain and simple. It comes up with an error every time saying: Object Required: 'Wscript'

  • How do I launch a winforms form from a DLL correctly?

    - by rodent31337
    There's another question similar to mine, but I wanted to gather some specifics: I want to create a DLL that is called from unmanaged code. When the unmanaged functions are called in the DLL, I want to collect information and show it in a kind of form. What I'd like to do is, when DllMain() is called, and the reason is DLL_PROCESS_ATTACH, I would like to instantiate a form. This form should be run on a separate thread. When my function FOO() inside my DLL is called, I would like to take the information from FOO(), dispatch it to the form for rendering. So, more specifically: i) What is the proper way to create a DLL project and have the ability to have Windows forms created in the designer be available to the DLL? ii) What is the correct way to give this form its own thread and message processing loop? iii) How do I dispatch information from the unmanaged DLL functions to the form, or, alternatively a managed class that can update its own state and the form? The form inside the DLL is sort of a "monitor" for data passing in and out of the DLL, so I can keep track of errors/bugs, but not change the core functionality of the DLL functions that are available.

  • Should I use Java for a custom Swing component designed for a clojure app?

    - by nansen
    I want a simple timeline component (like in video editing software) for a clojure/seesaw app and I am wondering if it is a good approach to implement this directly with clojure and seesaw or if I should write it in java and make my clojure wrapper around it. Or more generally: is a functional programming language optimal for writing UI widgets? I cannot imagine doing that without a lot of state involved. And wasn't OO invented for UI-development in the first place?

  • event handling in C++

    - by Max
    Hi. I'm writing a game in C++, and I'm trying to get it to recognize keyboard and mouse events. Google tells me that boost.signal is suitable for event handling, but none of the code samples or tutorials I've found tell me how to associate a keypress or mouseclick with a function. Can anyone shed any light on this?

  • Android moving back to first activity on button click

    - by cppdev
    I am writing a application where I am dealing with 4 activities, let's say A, B, C & D. Activity A invokes B, B invokes C, C invokes D. On each of the activity, I have a button called "home" button. When user clicks on home button in any of the B, C, D activities, application should go back to A activity screen ? How to simulate "home" button in this case ?

  • Linux directories

    - by Alex Farber
    I am writing installation script for my program, which is supposed to run on Linux/Unix OS. What is the default directory for the following files: Executable files (programs). Program should be executed by typing its name from the command line. Shared libraries. Third-party shared libraries (the program is not open source, so I need to redistribute third-party libraries). Read-only program configuration files for all users. Configuration data available for read/write access for all users.

    - by TooFat
    I have Console Application written in C# that is scheduled to run every 15 min. or so using the Built in Windows Task Scheduler. Every time it runs the black console box pops up for the duration of it's execution and then closes. I am not writing anything to the console. Is there a way to make this run in the background?

  • Job queueing and execute Mechanism

    - by Calm Storm
    In my webservice all method calls submits jobs to a queue. Basically these operations take long time to execute, so all these operations submit a Job to a queue and return a status saying "Submitted". Then the client keeps polling using another service method to check for the status of the job. Presently, what I do is create my own Queue, Job classes that are Serializable and persist these jobs (i.e, their serialized byte stream format) into the database. So an UpdateLogistics operation just queues up a "UpdateLogisticsJob" to the queue and returns. I have written my own JobExecutor which wakes up every N seconds, scans the database table for any existing jobs, and executes them. Note the jobs have to persisted because these jobs have to survive app-server crashes. This was done a long time ago, and I used bespoke classes for my Queues, Jobs, Executors etc. But now, I would like to know has someone done something similar before? In particular, Are there frameworks available for this ? Something in Spring/Apache etc Any framework that is easy to adapt/debug and plays well along with libraries like Spring will be great.

  • Devise password reset issue (new_user?)

    - by rabid_zombie
    When a user's email is inputted into the forgot password form and submitted, I am receiving an error saying login can't be blank. I looked around devise.en.yml for this error message, but can't seem to find it anywhere. Here is my views/devise/passwords/new.html.haml: %div.registration_page %h2 Forgot your password? = form_for(resource, :as => resource_name, :url => user_password_path, :html => { :method => :post, :id => 'forgot_pw_form', :class => 'forgot_pw' }) do |f| %div = f.email_field :email, :placeholder => 'Email', :autofocus => true, :autocomplete => 'off' %div.email_error.error %input.btn.btn-success{:type => 'submit', :value => 'Send Instructions'} = render "devise/shared/links" The form is posting to users/password like it should, but I noticed that my forgot password form attaches class = 'new_user'. Here is what my form displays: <form accept-charset='UTF-8' action='/users/password' class='new_user' id='forgot_pw_form' method='post' novalidate='novalidate'></form> My routes for devise (I have custom sessions and registrations controllers): devise_for :users, :controllers => {:sessions => 'sessions', :registrations => 'registrations'} How can I setup devise's forgot password functionality? Why am I receiving this error message and why is that class being added there? I've tried: Adding my own passwords controller and adding new routes for my custom controller. Same error Adding my own class and id to the form. This successfully changes the id and class of the form, but reverts back to class and id of new_user Thanks.

  • Python class structure ... prep() method?

    - by Adam Nelson
    We have a metaclass, a class, and a child class for an alert system: class AlertMeta(type): """ Metaclass for all alerts Reads attrs and organizes AlertMessageType data """ def __new__(cls, base, name, attrs): new_class = super(AlertMeta, cls).__new__(cls, base, name, attrs) # do stuff to new_class return new_class class BaseAlert(object): """ BaseAlert objects should be instantiated in order to create new AlertItems. Alert objects have classmethods for dequeue (to batch AlertItems) and register (for associated a user to an AlertType and AlertMessageType) If the __init__ function recieves 'dequeue=True' as a kwarg, then all other arguments will be ignored and the Alert will check for messages to send """ __metaclass__ = AlertMeta def __init__(self, **kwargs): dequeue = kwargs.pop('dequeue',None) if kwargs: raise ValueError('Unexpected keyword arguments: %s' % kwargs) if dequeue: self.dequeue() else: # Do Normal init stuff def dequeue(self): """ Pop batched AlertItems """ # Dequeue from a custom queue class CustomAlert(BaseAlert): def __init__(self,**kwargs): # prepare custom init data super(BaseAlert, self).__init__(**kwargs) We would like to be able to make child classes of BaseAlert (CustomAlert) that allow us to run dequeue and to be able to run their own __init__ code. We think there are three ways to do this: Add a prep() method that returns True in the BaseAlert and is called by __init__. Child classes could define their own prep() methods. Make dequeue() a class method - however, alot of what dequeue() does requires non-class methods - so we'd have to make those class methods as well. Create a new class for dealing with the queue. Would this class extend BaseAlert? Is there a standard way of handling this type of situation?

  • Run multiple copies of an app from Visual Studio

    - by HeavyWave
    How can I run multiple copies of the same app in Debug with Visual Studio? For instance, how do I run app.exe /option1 and app.exe /option2 and still debug both? I know I can run them manually and then attach, but I want an automated solution. I have tried writing a small console app just to run 2 processes, but obviously they are not being run under debugger. Any ideas?

  • Best Practices For Secure APIs?

    - by Ferrett Steinmetz
    Let's say I have a website that has a lot of information on our products. I'd like some of our customers (including us!) to be able to look up our products for various methods, including: 1) Pulling data from AJAX calls that return data in cool, JavaScripty-ways 2) Creating iPhone applications that use that data; 3) Having other web applications use that data for their own end. Normally, I'd just create an API and be done with it. However, this data is in fact mildly confidential - which is to say that we don't want our competitors to be able to look up all our products every morning and then automatically set their prices to undercut us. And we also want to be able to look at who might be abusing the system, so if someone's making ten million complex calls to our API a day and bogging down our server, we can cut them off. My next logical step would be then to create a developers' key to restrict access - which would work fine for web apps, but not so much for any AJAX calls. (As I see it, they'd need to provide the key in the JavaScript, which is in plaintext and easily seen, and hence there's actually no security at all. Particularly if we'd be using our own developers' keys on our site to make these AJAX calls.) So my question: after looking around at Oauth and OpenID for some time, I'm not sure there is a solution that would handle all three of the above. Is there some sort of canonical "best practices" for developers' keys, or can Oauth and OpenID handle AJAX calls easily in some fashion I have yet to grok, or am I missing something entirely?

  • Google App Engine/Simple HTML, how to write input boxes with google autocomplete

    - by Calm Storm
    I am writing a GAE application and I would like to have an input box with google auto-suggest. Specifically, when a user types "Shawshank" I would like to see google's suggestions in my drop down. Can someone tell me what are the different ways of doing this? I understand I may have to use some javascript libraries so any code samples etc will help immensely. (Pure javascript/jquery kinda solutions will be more preferable)

  • STL container to pop() by priority?

    - by Pirate for Profit
    I'm writing a thread-pool for Qt as QRunnable doesn't handle event loops in new threads. Not too familiar with STL, what would be the best way to pop() something by priority? Priority should probably be a property of MyRunnable imo, but I can always give that info to an STL container when adding the runnable to the queue.

  • Should I bother with C++ or go straight to C#?

    - by Pat Riley
    I have been writing embedded C applications for almost 20 years. In the last few years I have written quite a few PC based GUI interfaces in Visual C so I could interface my embedded systems to a PC. Although my primary work will still be in deeply embedded C, I have finally decided to move my PC based tools into Ruby - (for quick scripting type stuff) and C++ or C# for GUI based interfaces and applications. Should I bother with C++ or just move straight to C#?

  • How can I filter then modify e-mails using IMAP?

    - by swolff1978
    I have asked this question in a different post here on SO: How can a read receipt be suppressed? I have been doing some research of my own to try and solve this problem and accessing the e-mail account via IMAP seems like it is going to be a good solution. I have successfully been able to access my own Inbox and mark messages as read with no issue. I have been asked to preform the same task on an Inbox that contains over 23,000 emails. I would like to run the test on a small amount of e-mails from that inbox before letting the whole 23,000 get it. Here is the code I have been running via telnet: . LOGIN [email protected] password . SELECT Inbox . STORE 1:* flags \Seen 'this line marks all the e-mails as read So my question is how can i execute that store command on a specific group of e-mails... say emails that are going to / coming from a specific account? Is there a way to like concatenate the commands? like a FETCH then the STORE? Or is there a better way to go about getting a collection of e-mails based on certain criteria and then modifying ONLY those e-mails that can be accomplished through IMAP?

  • iPhone App made using XCode 3.2.3 does not run on 3.1.3 OS

    - by balexandre
    I can't figure this out and I thought that someone might run through the same thing. I have XCode 3.2.3 (Pre Release with OS 4 beta) and I started to create my application, after the final touches and everything worked ok, I changed the Simulator - 4.0 to Simulator - 3.1.3 (latest iPhone OS) and I could never start my app again :-( Does anyone know what I should do? I created a simple Screencast of the problem so everyone can see what I'm writing about. Thank you for all the help.

  • Easy command line Java compile

    - by Nash0
    So I have to send a java project to someone outside our company who has no experience with java and they need to compile it. Is there an easy way to do it on the windows command line that does not require writing out lists of the files? Personally I think javac should be smart enough to handle javac * when in the folder just under the root of the package hierarchy. Is there anything in this ballpark?

  • How to notify a Windows .net service from PHP on Linux?

    - by Louis Haußknecht
    I'm writing a service in C# on Windows which should be triggert by an PHP driven web frontend, which runs on Linux. Both processes share the same SQL Server 2005 database. There is no messaging middleware available atm. The PHP process inserts an row in a SQL Server table. The Windows process should read this entry and process it. I have no experience in PHP, so what would you suggest to notify the Windows process?
