• how does teamviewer find my computer even if my comp. behind of the firewall and firewall isn't conf

  - by uzay95

  Did you use teamviewer? (comic question i know... Who doesn't use it?) Do you have any idea how does teamviewer make connection even if i am behind the router, firewall, switch and my local firewall..? I'm trying to imagine a connection that is between remote machinge and my computer. Remote machine is sending the packets (and its header (for instance, destination IP, message body)) to me but it only knows my id number(which is given by my local teamviewer application). And this packets are reaching to my computer even if there is a juniper firewall (and also my windows firewall). What kind a message body is recieving by computer? (of course it is not like xml, text, html, excel :) Do you have any idea? PS. Please share your knowledge like you are explaining to beginner level user.

• Showing custom model validation exceptions in the Django admin site.

  - by Guy Bowden

  I have a booking model that needs to check if the item being booked out is available. I would like to have the logic behind figuring out if the item is available centralised so that no matter where I save the instance this code validates that it can be saved. At the moment I have this code in a custom save function of my model class: def save(self): if self.is_available(): # my custom check availability function super(MyObj, self).save() else: # this is the bit I'm stuck with.. raise forms.ValidationError('Item already booked for those dates') This works fine - the error is raised if the item is unavailable, and my item is not saved. I can capture the exception from my front end form code, but what about the Django admin site? How can I get my exception to be displayed like any other validation error in the admin site?

• vb.net : is it possible to connect to sql server 2008 via odbc but not through vb.net code?

  - by phill

  I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically? the error i keep receiving in the app is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) however I can connect to it when I create a system dsn to the sql server instance and through VS2005's Tools Connect to Database. Here is the code I'm using to connect: dim strC as string strC = "data source=bob; database=subscribers; user id=bobuser; password=passme" dim connection as New SqlClient.SqlConnection(strC) try connection.open() catch ex as Exception msgbox(ex.message) end try connection.Close()

• Input checkbox name converts period signs into underlines on post

  - by Rakoon

  Hello I am working on an image gallery at the moment. When a user is logged in, an x appears over each image and a checkbox next to it to enable the user to delete that image. Only if the checkbox is checked will the image be deleted. They are both in a (one for each image in the gallery), the small image "x.gif" is an input type="image" that submits the $_POST form. The checkbox inherits the name of the image and is to prevent accidentally pressing the x button and deleting an image. The problem is that the checkbox name, upon posting it gets converted from (for instance) "Image.jpg" to "Image_jpg" When i test it with print_r($_POST); Should I create code for replacing _jpg or _gif into .jpg and .gif after the post or is there a way to make it possible to use period signs in input names? Any help is greatly appreciated.

• Windows azure deployment

  - by smoothe

  I just built a simple hello world windows azure service containing just one web role, I used visual studio 2008 and Windows azure tools for VS 1.2 I am pretty new to this and I have been trying to deploy an application all afternoon now. I'm in australia and deploying in the region Asia anywhere. I have pretty much followed the info provided on MSDN and it says uploaded 95% then after about ten minutes the deployment disappears. I have tried using the old windows azure developer portal and 30minutes later I can not access the service and it's status is either busy or stopped. I have the introductory offer for an extra small compute instance on the subscription I am deploying to. Can anyone with experience with windows azure elaborate on the subject of deploying apps and the status on my application, I am very keen to get into the platform and this issue has just about spoiled my weekend.

• How to create a fully qualified hyperlink to a resource dynamically?

  - by Slauma

  In ASP.NET I'd like to create a link which points to a specific Uri and send this link in an email to a user, for instance something like http://www.BlaBla.com/CustomerPortal/Order/9876. I can create the second part of the Uri /CustomerPortal/Order/9876 dynamically in code-behind. My question is: How can I create the base Uri http://www.BlaBla.com without hardcoding it in my application? Basically I want to have something like: http://localhost:1234/CustomerPortal/Order/9876 (on my development machine) http://testserver/CustomerPortal/Order/9876 (on an internal test server) http://www.BlaBla.com/CustomerPortal/Order/9876 (on the production server) So is there a way to ask the server where the application is running: "Please tell me the base Uri of the application" ? Or any other way? Thank you in advance!

• Are @property's necessary for Interface Builder?

  - by Rits

  In my UIViewController subclass, I have 3 UIView's with each a @property as an IBOutlet. I do not use these properties at all in my code. The views get instantiated as soon as the view controller is created and they are deallocated when the view controller is deallocated. I was thinking; can't I just remove the @property's? I did, and I could still connect my instance variables (with IBOutlet) in Interface Builder. So my question now is; is there any use for properties in combination with Interface Builder, or is it OK to leave them out? Is it required for some memory management or something? Or are they really just for use in your own code? And if I do leave them out, do I still need to release them in dealloc?

• Joomla contact form doesn't pass W3C validation

  - by aramaz

  Hi, I get the following error when I try to validate a contact page on my site: document type does not allow element "script" here The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed). One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error). I am using Joomla 1.5.7, and the doctype is <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Any idea how to fix this?

• Difference in techniques for setting a stubbed method's return value with Rhino Mocks

  - by CRice

  What is the main difference between these following two ways to give a method some fake implementation? I was using the second way fine in one test but in another test the behaviour can not be achieved unless I go with the first way. These are set up via: IMembershipService service = test.Stub<IMembershipService>(); so (the first), using (test.Record()) //test is MockRepository instance { service.GetUser("dummyName"); LastCall.Return(new LoginUser()); } vs (the second). service.Stub(r => r.GetUser("dummyName")).Return(new LoginUser()); Edit The problem is that the second technique returns null in the test, when I expect it to return a new LoginUser. The first technique behaves as expected by returning a new LoginUser. All other test code used in both cases is identical.

• Why can't I access Jetty running on my Mac via my iPhone?

  - by bpapa

  I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

• Dynamically Loading a DLL

  - by TooFat

  I am trying to simply load a dll written in C# at run time and create an instance of a class in that dll. Assembly a = Assembly.LoadFrom(@"C:\Development\DaDll.dll"); Type type = a.GetType("FileReleaseHandler", true); TestInterface.INeeedHelp handler = Activator.CreateInstance(type) as TestInterface.INeeedHelp; No errors are thrown, and if I step through the code I can walk though the FileReleaseHandler Class as it executes the constructor but the value of handler is always null. What am I missing here? or even is there a better way I should be going about this?

• Using the JNotify library, how can you tell if a deleted file was a file or a directory?

  - by Moeri

  For those unfamiliar with JNotify, this is a library which provides an easy way to monitor events in a directory. For instance, when a file gets deleted in the selected folder, the method "fileDeleted" gets called, along with a few parameters. Here's an example of the fileDeleted method: public void fileDeleted(int wd, String rootPath, String name) { print("deleted " + rootPath + " : " + name); } Now, I would like to know if the deleted file was a file or directory. My usual approach is to create a new File object with the given path, and use the methods isFile() and isDirectory() However, since this file is already deleted, these methods always return false. So here's my concrete question: I have the path to a deleted file or directory, how can I tell wether it was a file or a directory? Is there a workaround to this? What's the best practice to do here? Thank you in advance.

• Object pointer value as key into dictionary

  - by Ranking Stackingblocks

  I want to use the object's reference value as a key into a dictionary, as opposed to a copy of value of the object. So, I essentially want to store an object associated with a particular instance of another object in a dictionary and retrieve that value later. Is this possible? Is it completely against the idea of NSDictionary? I can tell that I am probably approaching this the wrong way because the dictionary wants me to implement NSCopying on the object itself, which doesn't really make sense in terms of what I'm doing. I can see that what I should really be doing is wrapping the pointer value, but that seems a little mad. Advice would be appreciated.

• RFC Repository of programming RFC's with ability to direct-link sections or even lines?

  - by Lasse V. Karlsen

  Forgive me if this is the wrong place to ask this, I feel like the question is slightly off-topic even though it is also about programming. I am inputting todo-tasks for my WebDAV-project into my issue tracker, as I read through the relevant RFC's, and it would be nice to be able to add a link in my issue text directly to the relevant text, instead of just a link to the RFC file with a section number in the issue text, and then I have to use the find function to find it. For instance, a link like this: http://ieft.org/rfc2518.txt#1000 <-- line 1000 http://ieft.org/rfc2518.txt#9.8.3 <-- section 9.8.3 Neither of these two works, since they just post the full text files, so my question is this: Does anyone know of hosted versions of the RFC documents that contains such links?

• How to create a static delegate from main-viewcontroller?

  - by geforce

  Hi, hope someone can help me on learning some new stuff about delegates in iOS-programming. I have a "MainViewController" which is the first VC when the app starts. I´ve a kind of modelselection with different UIImageViews and after choosing one of them, i´m pushing a new VC. I want to handle the modelChoice with a delegate, so all other viewControllers can listen to that and act based on the users choice. But does that mean that i have to alloc a new instance of that "MainViewController" in every VC? Whats the solution on that? How do i create (i think its called) static delegate? Would be great to learn that.. Thanks for sharing..

• should variable be retained or not? iphone-sdk

  - by psebos

  Hi, in the following piece of code I got from a book. The NSString *pPath which is defined in the class as an instance variable. @interface MainViewController : UIViewController { NSString *pPath; } In the implementation after being set it is being retained. I assume that with the assignment the object is automatically retained (because it is an NSString) and there is no need to additionally retain it. - (void) initPrefsFilePath { NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; pPath = [documentsDirectory stringByAppendingPathComponent: @"flippingprefs.plist"]; [pPath retain]; }

• Disadvantages of hard coding credentials? What's the resolution?

  - by SeeBees

  I am building a Sharepoint web part that will be used by all users. The web part connects to a web service which needs credentials with higher privileges than common users. I hard coded credentials in the web part's code. query.Credentials = new System.Net.NetworkCredential("username", "password", "domain"); query is an instance of the web service class This may not be a good approach. In regard with security, source code of the web apart is available to people who are not allowed to see the credential. This is bad enough, But is there any other drawback of this approach? How to prevent hard coding credentials into the source code? Thanks

• Ideal timeout period for dns lookup

  - by railscoder

  In my rails app i do a nslookup using a ruby library resolv. If the site like dgdfgdfgdfg.com is entered its talking too long to resolve. in some instance like 20 sec.(mostly for non-existent sites) Because it cause the application to slowdown. So i though of introducing a timeout period for the dns lookup. What will be the ideal timeout period for the dns lookup so that resolution of actual site doesnt fail. will something like 10 sec will be fine?

• linux's fork and system resources

  - by Dmitry Bespalov

  Suppose I have following code in linux: int main() { FILE* f = fopen("file.txt", "w"); fork(); fwrite("A", 1, 1, f); fclose(f); return 0; } What I know about fork from documentation, is that it makes the copy of current process. It copies state of the memory as well, so *f should be equal in both instances. But what happens with system resources, such as a file handle? In this example I open the file with write intentions, so only one instance can write into file, right? Which of the instances will actually write into file? Who should care further about the file handle, and call fclose() ?

• Retractable button bar using animations

  - by AndroidDev

  I want to create a button bar that is retractable: when the user clicks on a special "handle" button, the button bar should slide out of view partially so only the handle remains visible. When the bar is in retracted state only the handle is visible. Clicking on the handle should "slide out" the button bar so it is completely visible again. Ideally, the bar would start out in retracted state. I have tried some approaches using TranslateAnimation, including using a layout animation or calling "View.startAnimation" when the handle is clicked, but no luck so far. Do you guys have any tips how to approach this? Is there any decent documentation out there regarding Android animations? The documentation I find is sketchy at best. For instance, I found examples that cause a view to slide into view automatically using TranslateAnimation and a LayoutAnimationController when calling "addView", but when I call removeView no animation seems to be triggered at all, even if I set an animation that should create the opposite motion.

• How to write custom SQLite functions in Javascript inside a Webkit browser?

  - by Jay Godse

  I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

• inconsistency between Sun JRE javac and Eclipse java compiler?

  This confuses me. The following compiles fine under Eclipse. package com.example.gotchas; public class GenericHelper1 { static <T> T fail() throws UnsupportedOperationException { throw new UnsupportedOperationException(); } /** * just calls fail() * @return something maybe */ public boolean argh() { return fail(); } public static void main(String[] args) { // TODO Auto-generated method stub } } But if I try to do a clean build with ant, or at the command line with javac, I get this: src\com\example\gotchas\GenericHelper1.java:14: type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds boolean,java.lang.Object public boolean argh() { return fail(); } ^ 1 error what gives, and how do I fix it?

• Recommendation for tool/framework that follows the naked objects pattern?

  - by Marcus Munzert

  I am searching for a tool/framework that follows the naked objects pattern and is written in Java. I know about tools like for instance JMatter, Naked Objects and Domain Object Explorer. That's not exactly what I am searching for, though. Open source would be great, but doesn't need to be. My intention is to use that tool/framework for the purpose of model-driven software development to do the modeling part. Ideally, such a tool/framework would provide the option to use JPA to store/load objects.

• Trying to programmatically add a SQL Alias to the registry (just need help with parameters)

  - by nycgags

  Normally when we spin up a new instance we need to add an alias on one of our boxes so we can easily connect to it through SSMS using SQL Server Configuration Manager. I have written a batch file which adds the appropriate entry into the registry (it is actually two batch files, one for 32 bit and one for 64 bit). I am not sure how to get this to run with parameters though. I know %1 and %2 would be for the first two parameters, but when I run this, in the registry it actually puts %1 and %2 as the value pair. if you hardcode hostname and IP Address in place of %1 and %2 the batch file works as expected: REGEDIT4 ; @ECHO OFF ; CLS ; REGEDIT.EXE /S "%~f0" ; EXIT [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo] "%1"="DBMSSOCN,%2,1433"
