  • calling a service from an activity

    - by newbie
    Hi,I have been stuck on this issue for quite some time now.Have read the documentation and many tutorials and they just confuse me more.I hope someone will provide me a straightforward answer.It's really important.Thank you.. Ok ..so i want an activity to get some input from the user as and then send that string to a service.Then i want my service to run in a way so that i can use other applications while this one keeps running in the background.Also i don't want the service to keep running every second.What i want is for the service to get updated location of my current position every 10 minutes so i was thinkin if there could be a way to make my service to go to sleep n wake up evry 10 mins n check for updates.I don't want to show the update on the UI so i dont think i need to use an AIDL approach and also dont need to bind to the service.I js simply want to start the service as soon as the user enters the string and keep the service runing every 10 mins.I think it is really simple but m very confused.Please help.

  • RSA encrypted data block size

    - by calccrypto
    how do you store an rsa encrypted data block? the output might be significantly greater than the original input data block size, and i dont think people waste memory by padding bucket loads of 0s in front of each data block. besides, how would they be removed? or is each block stored on new lines within the file? if that is the case, how would you tell the difference between legitimate new line and a '\n' char written into the file? what am i missing? im writing the "write to file" part in python, so maybe its one of the differences between: open(file,'w') open(file,'w+b') open(file,'wb') that i dont know. or is it something else?

  • how to make the footer div start after all other divs have finished

    - by amit
    i am having a slight problem with the alignment of the footer div. i have a header at the top. div = maincontent { two divs for content, side by side. another 2 divs side by side below the content div. } //just to represent. i know this is not html ;) now i want the footer div to start after the maincontent div finishes. i can do that if i specify a fixed height for the maincontent div. but i dont want to specify a height for it. if i dont specify the height, the footer div starts at the middle of the page. what am i doing wrong?

  • Controlling the visibility of a Bitmap in .NET

    - by ET
    Hi everyone, I am trying to create this simple application in c#: when the user double clicks on specific location in the form, a little circle will be drawn. By one click, if the current location is marked by a circle - the circle will be removed. I am trying to do this by simply register the MouseDoubleClick and MouseClick events, and to draw the circle from a .bmp file the following way: private void MouseDoubleClick (object sender, MouseEventArgs e) { Graphics g = this.CreateGraphics(); Bitmap myImage = (Bitmap)Bitmap.FromFile("Circle.bmp"); g.DrawImage(myImage, e.X, e.Y); } My problem is that I dont know how to make the circle unvisible when the user clicks its location: I know how to check if the selected location contains a circle (by managing a list of all the locations containig circles...), but I dont know how exactly to delete it. Another question: should I call the method this.CreateGraphics() everytime the user double-clicks a location, as I wrote in my code snippet, or should I call it once on initialization?

  • Retrieving a page of that has a redirect

    - by Dmitry Makovetskiyd
    I get my page content with this function: private function fetch_url($url){ $ch=curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 320); $this->doc = curl_exec($ch); $this->status_code= curl_getinfo($ch, CURLINFO_HTTP_CODE); // echo $this->doc; curl_close($ch); } The problem is that with some urls dont exist on a webpage and there is a redirect to another page.. So say if I put the parameter: http://example.com/uncategorized/ It redirect me to : http://example.com/mature/ The problem is with curl, I dont get any content.. But my aim is to get the content of that page redirect.. Is there an easy way to get the function to work in the way I want..?

  • Webservice for uploading data: security considerations

    - by Philip Daubmeier
    Hi everyone! Im not sure about what authentification method I should use for my webservice. I've searched on SO, and found nothing that helped me. Preliminary Im building an application that uploads data from a local database to a server (running my webservice), where all records are merged and stored in a central database. I am currently binary serializing a DataTable, that holds a small fragment of the local database, where all uninteresting stuff is already filtered out. The byte[] (serialized DataTable), together with the userid and a hash of the users password is then uploaded to the webservice via SOAP. The application together with the webservice already work exactly like intended. The Problem The issue I am thinking about is now: What is if someone just sniffs the network traffic, 'steals' the users id and password hash to send his own SOAP message with modified data that corrupts my database? Options The approaches to solving that problem, I already thought of, are: Using ssl + certificates for establishing the connection: I dont really want to use ssl, I would prefer a simpler solution. After all, every information that is transfered to the webservice can be seen on the website later on. What I want to say is: there is no secret/financial/business-critical information, that has to be hidden. I think ssl would be sort of an overkill for that task. Encrypting the byte[]: I think that would be a performance killer, considering that the goal of the excercise was simply to authenticate the user. Hashing the users password together with the data: I kind of like the idea: Creating a checksum from the data, concatenating that checksum with the password-hash and hashing this whole thing again. That would assure the data was sent from this specific user, and the data wasnt modified. The actual question So, what do you think is the best approach in terms of meeting the following requirements? Rather simple solution (As it doesnt have to be super secure; no secret/business-critical information transfered) Easily implementable retrospectively (Dont want to write it all again :) ) Doesnt impact to much on performance What do you think of my prefered solution, the last one in the list above? Is there any alternative solution I didnt mention, that would fit better? You dont have to answer every question in detail. Just push me in the right direction. I very much appreciate every well-grounded opinion. Thanks in advance!

  • Database suggestion

    - by superartsy
    I am working on an enterprise level product that is designed around SQL Express Database ( views,concurrent users,stored procedures,case,IF).Though we dont use any SQL Server advanced features, if the database size of 4Gb in express ends up being a limitation customers can move to advanced versions of SQL Server. However my problem is, SQL Express deployment is not easy and the installer size is huge. This is a major drawback for someone looking to try our product.You dont want end users to not buy a product becos the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

  • C# Drag and Drop Effect with Overlay/Opaque Image

    - by CallMeLaNN
    Hi, I think this would be simple question and should be asked in the pas few years but unable to google around and dont know if there is a specific keyword. In c# WinForm I want to do drag and drop but I dont want the image of DragDropEffects Move, Copy or whatever. I want to display an image with half opaque. Just like Firefox when dragging an image, you would see the image folowing the mouse pointer like a ghost :) I already Implement DoDragDrop, DragEnter and DragDrop events. I just want to customize the dragging effects with overlay image.

  • PHP Security checklist (injection, sessions etc)

    - by NoviceCoding
    So what kind of things should a person using PHP and MySql be focused on to maximize security. Things I have done: -mysql_real_escape_string all inputs -validate all inputs after escaping em -Placed random alpha numerics before my table names -50character salt + Ripemd passwords Heres where I think I am slacking: -I know know nothing about sessions and securing them. How unsafe/safe is it if all you are doing is: session_start(); $_SESSION['login']= $login; and checking it with: session_start(); if(isset($_SESSION['login'])){ -I heard something about other forms of injection like cross site injection and what not... -And probably many other things I dont know about. Is there a "checklist"/Quicktut on making php secure? I dont even know what I should be worried about.I kinda regret now not building off cakephp since I am not a pro.

  • @Secured not working

    - by user3640507
    I am new to spring and trying to implement Role based authorization with the help of @Secured annotation. I have a method which is specifically for ADMIN and I have written @Secured ("ROLE_ADMIN") to secure it. @Secured ("ROLE_ADMIN") public void HelloUser(String name) { System.out.println("Hello ADMIN"); } Now when I call this method by creating a class object it gets called eventhough user dont have ADMIN authority But when I dont create an object and use @autowired annotation instead then it works i.e User is not allowed to access this method. In my security.xml as well as servlet.xml I have added <global-method-security secured-annotations="enabled" /> Can some one please tell me where I am going wrong or is this the natural behaviour in spring ?

  • How to Embed/Link binary data into a C++ DLL

    - by CrimsonX
    So I have a Visual Studio 2008 project which has a large amount of binary data that it is currently referencing. I would like to package the binary data much like you can do with C# by adding it as a "resource" and compiling it as a DLL. Lets say all my data has an extension of ".data" and is currently being read from the visual studio project. Is there a way that you can compile or link the data into the .dll which it is calling? I've looked at some of the google link for this and so far I haven't come up with anything - the only possible solution I've come up with is to use something like ResGen to create a .resources file and then link it using AssemblyLinker with /Embed or /Link flags. I dont think it'd work properly though because I dont have text files to create the .resources files, but rather binary files themselves. Any advice?

    Hi, I am pretty new with GUI, and I guess that is a silly question, but I am stuck... I am trying to make a folder explorer using TreeView control. now, I added an ImageList with two images - one for a folder and the other for selected folder. I used the 'BeforeExpand' event to change the icon of the current node (folder). The problem is that I dont know how to change it back when the user selects other folder... what event can I use? Maybe I dont use it right... ? Thanks guys :)

  • Alternative to 'publish' in visual studio

    - by acidzombie24
    I am working on an app with configurable files. When i publish i notice 1) I get an installer which i dont think i can opt out of 2) I dont know where the install path is and if i change the config files the application will not install (maybe not run either if i edit them in the right place?) So what alternatives do i have? I would like some event i can run which builds in release mode then copies the release.exe and any config/media file and move it to path/deploy/prj/ so i can zip it or share it instead of a path in my sensitive path/src area (bonus is i can share deploy if i want all projects to be available (and no source)) Using visual studio 2010 -edit- also i need some data in src/relatedprj/bin/*, to be copied into the root

  • how to configure hibernate not to update @Version on each access to entity

    - by radai
    i have a simple query that returns an entity, and when i look at hibernate SQL output i see that when i execute this query hibernate updates the @Version field (on each consecutive read the @version field is updated). i dont modify anything in the entity i fetch, and i dont pass is as an argument to either persist or merge. this effectively means every read i make turns into a read+write. i've tried setting the lock mode t oboth NONE (jpa 2) and READ (jpa 1) to no avail. is there any way to achieve this? if so, is there any way to set this as the default behavior in persistence.xml in some way ? im using jpa2 over hibernate 3.6

  • How should I build a gaming community

    - by Przystojny
    I've been wanting to build my own gaming community site (like http://fragbite.com) for a long time, I have started many times but just quitted after a couple days because it gets very messy I've been palying around with php and mysql off and on for 3 years but i've never gotten in to oop. i have tried but i usually end up with the "old php". I usually build my pages like so that i include a file on top of all pages with neccasary functions, html head etc. And I mix php and html together which I dont mind but if I eventually would get a designer he would not like it i think. I have tried both phpcake and codeigniter and all those popular mvc's but its just to much, like they do all the work. i want to do it myself. but i dont know where to start. What would you do if you were me? Is there maybe some non-oop mvc? (Sorry for my english)
