• Put Raphael (SVG) canvas behind other divisions to make them clickable?

  - by Kerry

  I am using Raphael to create lines between divisions in an organization chart (or flow chart), but I need to be able to actually click on the divisions and content behind it. If I could make the canvas be behind the other elements, kind of like a background image, that would be idea. Is this possible? UPDATE: I found a solution. Raphael makes an SVG canvas that is absolutely positioned in my case. Absolute positions act as layers, and so to be on top of that layer, my content had to be absolutely positioned as well. If someone else has a better solution, I would be happy to hear it, though this is working fine.

• WorkFlow and WCF dynamically launching WorkFlows

  - by Raj73

  I have a WF which will be hosted on WCF . The service Contract will contain a single operation containing two parameters. Parameter1 will be a string and will contain the name of the workflow to invoke and parameter two will contain the input for the invoked Work Flow. All operations will take the same parameter. All the operations will return the same return value. I have created the service implementation and I would like to depending on the value of parameter1 start executing the appropriate workflow and return the value (There can be number of workflow classes say Operation1, Operation2...which will be the passed in as the value in Parameter1). How can I instantiate different workflow classes and pass parameters and get the return values from them which I should then pass back to the calling Client. (Also Should I be using ReceiveActivities in all of my Launchable WorkFlow Classes ? ) Any code samples or pointers would help

• Mercurial "server"

  - by user85116

  I've been using mercurial for a little while, but mainly for my own usage. Now though, I have a project I'm working on where two of us are building the same project, and we will probably be modifiying each other's files. I would like to setup a mercurial repo on a server, make that repo the "server", so my changes and the other editor's changes both push to that server (so basically the subversion / cvs model); I like mercurial though, and don't want to switch to something like subversion. Here in my own network, everything is done on linux, and my "server" has openssh installed. So pushing my changes (I work on multiple computers) from one computer to the server is just a matter of "hg push"; the protocol used is ssh for transfering the changes. The problem is that I use linux, the server will be windows (so no openssh, right?) and the other editor will be using windows too. As far as I know, the best way of working in mercurial in these types of setups is for the repo to pull changes from the source, rather then the source pushing to the "server". I'm behind several firewall's (not entirely my network) and my computer won't be visible from the server, and I'm assuming the other editor will be behind a firewall too (so we can't just start up the local mercurial http server and get the "server" computer to pull from that). What's the best way for both editors to get our changes to the server repo? (I should add that the server is a server on the internet, so just as visible as something like google.com. It's a hosted windows server, but I would probably have permission to install software if needed for this)

• Need help managing MySql connections

  - by David Jenings

  I'm having trouble finding a clear explanation of connection pooling. I'm building an app using the .NET connector I downloaded from mysql.com. The app only needs one db connection but will be running simultaneously on about 6 machines on my network. Normally, I'd create the connection at startup and just leave it. But I'm seeing lots of posts from people who say that's bad practice. Also I'm concerned about timeouts. My app will run 24/7 and there may be extended periods without database activity. I'm leaning toward the following: using (MySqlConnection conn = new MySqlConnection(connStr)) { conn.Open(); // use connection } But I'm not sure I understand what's going on in the background. Is this actually closing the connection and allowing gc to kill the object, or is there a built in pooling behavior that preserves the object and redelivers it the next time I try to create one? I certainly don't want the app reauthenticating across the network every time I hit the database. Can anyone offer me some advise?

• Framework for creating mock objects in Java

  - by Amir Rachum

  This is NOT a question about which is the best framework, etc. I have never used a mocking framework and I'm a bit puzzled by the idea. How does it know how to create the mock object? Is it done in runtime or generates a file? How do you know its behavior? And most importantly - what is the work flow of using such a framework (what is the step-by-step for creating a test). Can anyone explain? You can choose whichever framework you like for example, just say what it is.

• How can I tell what is using the memory when there is a heap overflow in Java?

  - by Grae

  Hi all, I know a little about profiling, but what I am particularlly insterest in, is what has all the memory when I get these heap over flow exceptions. I will start getting them after about a hour of debugging. I am hoping there is some sort of dump or something, that I can use to get a list of what instances are around at the time the program starts. By the way, sorry if this is a lazy question. I really shoud put sometime in learning about profiling. Grae

• Design cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• Creative an interactive GUI for a web application

  - by user2125844

  I have to create a web application (preferably using the Google App Engine) that will allow users to access it through a url link (not a Desktop application). The application graphically looks like a flow chart and each item in the chart can be selected to pull up a video (not in another window). It is recommended that I use Python. I have never made anything for the web before. Is there a best Python GUI API I should use? I've read quite a bit about Django so far I'm not sure if it is the best fit for this or not. Does anyone have any tips for starting this project? Thanks in advance!

• How to arrange labels in a flowlayout manner?

  - by Tim Büthe

  How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

• If cookie found, get data, else create cookie, is this good logic?

  - by Ryan

  I have an Action that basically adds an item to a cart, the only way the cart is known is by checking the cookie, here is the flow of logic, please let me know if you see any issue... /order/add/[id] is called via GET action checks for cookie, if no cookie found, it makes a new cart, writes the identifier to the cookie, and adds the item to the database with a relation to the cart created if cookie is found, it gets the cart identifier from the cookie, gets the cart object, adds the item to the database with a relation to the cart found so it's basically like... action add(int id){ if(cookie is there) cart = getcart(cookievalue) else cart = makecart() createcookie(cart.id) additemtocart(cart.id, id) return "success"; } Seem right? I can't really thing of another way that would make sense.

• selective UnknownHostException

  - by Stephan

  Hi everybody! I am getting said Exception in my program, but only in certain cases. First of all, I have the internet permission set:<uses-permission android:name="android.permission.INTERNET" />, and I tried the two method of this and this thread (they don't work in my case). The scenario is the following: I send a GET request to a rest service (e.g. http://my.web.site/request.php?attr=blah) and I do get a correct xml back. Now, in this xml there are some resources described, one of which is an url to an image (e.g http://my.web.site/images/img.jpg). Here it's where it fails! Here I consistently receive a UnknownHostException. I find it weird, since it's the same domain and everything. Accessing the img url from browser works (both from the emulator browser and pc browser). I tried from a device too but it doesn't get the image anyway. Any idea on why this weird behavior? EDIT: all my tests were on emulator and device, but connected to a wifi network. I tried also using the internet connection of my provider on the phone (i.e. bypassing home network), and still the behavior is the same... I found this bug which I assume is the source of this problem, but still no solution (after more than 1.5years). Any ideas?

• Can JPA do batch update | put | write | insert as pm.makePersistentAll() does in GAE/J

  - by Kenyth

  I searched through multiple discussions here. Can someone just give me a quick and direct answer? And if with JPA you can't do a batch update, what if I don't use transaction, and just use the following flow: em = emf.getEntityManager // do some query // make some data modification em.persist(..) // do some query // make some data modification em.persist(..) // do some query // make some data modification em.persist(..) ... em.close() How does this compare to batch update with regard to performance, and compare to a single transaction commit, measured by RPC calls to datastore server, CPU cycles per request, or so. Does every call to em.persist(..) before em.close() trigger a RPC call to the datastore server? Thanks very much for any response!

• Resetting Qt Style Sheet

  - by mree

  I've managed to style my QLineEdit to something like this: void Utilities::setFormErrorStyle(QLineEdit *lineEdit) { lineEdit->setStyleSheet( "background-color: #FF8A8A;" "background-image: url(:/resources/warning.png);" "background-position: right center;" "background-repeat: no-repeat;" ""); } I called the function using Utilities *util = new Utilities; util->setFormErrorStyle(lineNoStaf); The flow should be something like this: User open form User fill data User submit data Got error Use setFormErrorStyle() User edit the text in the QLineEdit and the style disappear This function should be reusable over and over again, but how can I connect QLineEdit signal such as textChanged() to a function in other class that will reset the Style Sheet and then disconnect the signal so that it won't be running continuously every time the text changed ?

• JAAS : on Callback ( Interesting based on HTTP headers )

  - by VJS

  I am using NameCallback and PasswordCallback for username and password.For username and password, popup comes on browser and when i enter username ans password, JAAS authenticates my request. On the wireshark, I have seen that 401 Unauthorized message (WWW-Authenticate header)comes and when i enter username/password HTTP request with credentials generate ( with Authorization header) and goes to server. My requirement : I don't want pop up to come.My application on other server having username / password, so once it received 401 then based on some logic it will generate HTTP request with Authorization header / credentials and sent it back. FLow : User - Other Server - My Tomcat5.5 Here on Other Server, nobody is available to enter username/password manually.Application is deployed and it will only generate HTTP request with credential and sent it back to tomcat. Can we have any other callback which behave like this.Need your help.Please provide me feedback as well related to approach.

• Creation of AsyncTask taking too much time Android

  - by user2842342

  I am making a network call in an AsyncTask, but the problem i am facing is the amount of time it is taking to start the doInBackground method. Here is a part of my code: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Log.d("Temp:",System.currentTimeMillis()+""); new Move().execute(); /*some other logic } } And my AsyncTask is: private class Move extends AsyncTask<Void, Void, Void> { @Override protected Void doInBackground(Void... temp) { Log.d("start:",System.currentTimeMillis()+""); gson.fromJson(Web.Request.get(some_URL),Void.class); Log.d("end:",System.currentTimeMillis()+""); return null; } } These are the logs i got: 32658-998/com.example.game D/temp:? 1408923006159 32658-998/com.example.game D/start:? 1408923035163 32658-998/com.example.game D/end:? 1408923035199 So actually it took almost 29 secs to reach the first line in doInBackground method, where as it took just 36 ms to finish the network call. I tried it many times, the time taken is almost in the same order. Is it possible to start the AsyncTask immediately? Or is there any other way to solve this problem.(other than a running a simple thread?) Thank you :)

• Android Service Testing with messages

  - by Sandeep Dhull

  I have a service which does its work(perform network operation) depending upon the type of message(message.what) property of the message. Then it returns the resoponse, also as a message to the requesting component(depending upon the message.replyTo). So, i am trying to write the testcases.. But how????? My Architecture of service is like this: 1) A component(ex. Activity) bounds to the service. 2) The component sends message to the Service(using Messenger). 3) The service has a nested class that handles the messages and execute the network call and returns a response as message to the sender(who initially sent the message and using its replyTo property). Now to test this.. i am using Junit test cases.. So , in that .. 1) in setUp() i am binding to the service.. 2) on testBusinessLogic() . i am sending the message to the service .. Now problem is where to get the response message.

• Switching back into the middle of a function in Actionscript

  - by J.Ded.

  I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards. The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

• How to make an element slide with the viewport as it scrolls?

  - by alex

  I've Googled for this but must be using the wrong keywords. Basically I want to use the effect that Magento and now Stack Overflow uses. That is, there is an element in a column, and when you scroll down, it sticks to the top of the viewport. And once scrolled up again, it goes back into the normal page flow. This Ask A Question is a good page for example. Scroll down and watch the "How to Format" element come down (might need to make your viewport smaller if you have a large screen to see the effect). I've noticed it is setting position: fixed in the CSS. The JavaScript however is obfuscated. What's the easiest way to achieve this effect? Is there a jQuery plugin available?

• Creating folders and uploading a file without using a web browser

  - by Ashpak

  I am using the Java Api We have a web application wherein we want our file to be uploaded on an on_click even on some submit button. We don't want the browser to prompt us to enter the username and password to get the access token. Instead, we can provide the username and the password through the code so that we get the access token and the file will be uploaded directly. Right now, OAuth 2 requires that we enter the username and password to be entered through the browser. Reading through the post, I see that we can authenticate for the first time, obtain a refresh token and then keep on refreshing that token periodically. But our application requirements does not allow for this work-flow. Is there any way to automate the process of entering the user credentials using Java code. or Is there any library that will keep the browser away from the process.

• Generic SQL builder .NET

  - by Patrick

  I'm looking for a way to write an SQL statement in C# targeting different providers. A typical example of SQL statements differentiating is the LIMIT in PostgreSQL vs. TOP in MSSQL. Is the only way to solve SQL-syntax like the two above to write if-statements depending on which provider the user selects or using try catch statements as flow control (LIMIT didn't work, I'll try TOP instead)? I've seen the LINQ Take method, but I'm wondering if one can do this without LINQ? In other words, does C# have some generic SQL Provider class that I have failed to find that can be used?

• How to handle redirections with codeigniter?

  - by SinneR

  Hi, im having problems starting a codeigniter project, the problem is that when i do something in a controller and then i want a page to display the result, an example: i have a form to add a item to the database, i get all the data in the controller and save it to database and then i want (if all went well) to redirect to the main page with a success msg, i was doing this with $this->load->view('admin', $data); the problem is that the url keeps saying admin/addItem so everytime the page gets refreshed it adds another item, now i found the: redirect('admin','refresh'); but this only helps me when i dont need to display any msg because this function dont allow to send a $data var. Any ideas? Probably this is really easy to fix but i cant find a way to handle the flow of the application the way i want, any help is apreciated. thanks ;)

• Can I float a block of text like an image?

  - by george.entenman.name

  If you change "float:right" to "float:left" in this W3schools example, you'll get an image floating to the left of the paragraph. I want to do the same thing with a block of text. The purpose is to be able to have little annotations to the left of paragraphs. If you know of any way to do this, I'd be very grateful. I'd be really grateful (and amazed) if there were a way to place this annotation midway in a paragraph and have text flow around it. I've searched all over for an answer but possibly don't know how to ask the question so that search engines can help me. So now I'm appealing to humans!!

• Non-floated div drops below right floated div in IE9 (and 7)

  - by PVA

  This is a responsive site, (http://www.dermatologypartners.com) with desktop styles first. IE8 handles the pages correctly, though without CSS3 flourishes. But IE9 is dropping my navbar (on left) down, when it is up next to the right floated content in all the other browsers. My navbar is near the end of the HTML because I want it to flow over LAST, below page content but above the footer, in the smartphone version of the site -- which it does. The nav is NOT floated. It just rises to the top left and content is floated to the right. Except in IE9. I don't to have to redo all this, if I can just get an IE9 fix. It's not "float drop" - there's plenty of room available. I'm actually having the same problem in IE7, but I'm not concerned with IE7 -- but why 7 & 9, while 8 is fine? Thanks!

• Is it practical to build a web site using strict XHTML and relying on CSS 100% for visual style?

  - by Micah

  I tend to take the academic approach all too often and adhere to strict principles in my development when the reality is that I could have finished the project sooner had I been a little less cautious. I'm looking to find the right amount of practicality. I want to take the "Zen" approach to designing a site which (in my words) says "Use HTML strictly for content structure, and let the CSS magic do the rest". How practical is this in reality? One of the issues I run into is that I want to develop (make functional) the site first, then come back in and design it later. I know structure-wise how I want the site to flow, but I haven't even begun playing with the CSS layout, graphics, or any of the other designy stuff. What is the right approach here?
