• Send custom data when initializing java WebService over soap

  - by Mesni

  Hello. I have a question about sending additional data over soap to the functions. My webService function requests only one integer, for example an getDocumentPrivilage(DocumentID). In another WebService user registered and he got an unique ID, so the other application can see who he is. So on Service one he registers, gets id and it has to send it to the other webservice tor the privilage. Id dont wish to rewrite the function so that it gets the unique ID (like this getDocumentPrivilage(uniqID,DocumentID)) but, the wish is that i would be able to create a client that sends this data at the initialization or somehow as some sort of parameter behind the function. Is this possible?? I tried the ServiceLifecycle but cant see any setting i've given in. Im using WebSphere CE for the server and Jax-ws Creating the webapp in java. Thank you very much in advance. lp, Mesni

• C# cross class enum visibility - Possible?

  - by 537mfb

  so i have a class ClassA that contains an enum MyEnum, and a class ClassB that references that class (different Projects) and so in ClassB i have a using ClassA; clause and i can access that enum using something like MyEnum value = MyEnum.EnumValue; Now on a third project i have my Windows form and it has a clause like using ClassB; Now what can i add in ClassB to acess that enum on my windows Form? Is it even Possible? i would like to avoid having to add ClassA to my form just to access an enum. The idea is that ClassB is sort of a manager between my form and the functionality in ClassA - but i would like to get access to that enum as it makes a lot of tasks easier

• Foraward SNMP requests from Agentx Master to Agentx Subagent

  - by Nadia

  I am running an agentx master and an agentx subagent on linux. When I run snmpget on a default MIB i.e. sysdescr.0 it returns fine, but when I request for a MIB that was registered through the agentx subagent it timesout. It appears that the master receives the GET request but does not forward on to the agentx subagent. The MIB is registered successfully but when master agentx receives the GET request it saying "Sending 60 bytes to UDP: unknown". It can't find the location to forward to. Am I missing a configuration of some sort on the subagent side? How does the master know who is suppose to receive the requests?

• Creating a db driven primary navigation in django?

  - by Fedor

  I find that it's pretty common most people hardcode the navigation into their templates, but I'm dealing with a pretty dynamic news site which might be better off if the primary nav was db driven. So I was thinking of having a Navigation model where each row would be a link. link_id INT primary key link_name varchar(255) url varchar(255) order INT active boolean If anyone's done something similar in the past, would you say this sort of schema is good enough? I also wanted for there to be an optional dropdown in the admin near the url field so that a user could choose a Category model's slug since category links would be common, but I'm not quite sure how that would be possible.

• What is better for non-active directory stuff, WMI or ADSI?

  - by nbolton

  I've used both technologies in C# for some time now and thus far have not been able to figure out which is better (in terms of ease of use). It seems to me that because there is support for Windows 95 in WMI, it's an older technology than ADSI (which I assume was invented along with Active Directory). However, despite the hint that ADSI is "for AD", I've used it for several non-AD things, such as managing IIS and local users. So, for those sort of tasks (managing IIS and local users), which is more practical? WMI or ADSI? Consider also that I'm using C# to implement these technologies, not vbscript. However, this may equally apply to vbscript.

• What are my options for streaming for silverlight?

  - by Will I Am

  I would like to implement limited scope streaming (LAN, multicast, even broadcast) where the client is implemented in silverlight. More importantly, I would like to stream from a desktop OS, not a server OS. As a result, I can't use the MS media server, which I believe requires WS2003 or WS2008. Ideally the solution would have some sort of API so I can plug in or provide a custom frame source. If I need to encode my own video, how can I encode using H.264 or another Silverlight supported codec? if I need to implement my own server, where can I find information about how a client starts to receive a stream? thank you! I know, it's a lot of questions, but it basically boils down to "how do I stream from a non-server OS?"

• What is the '^' in Objective-C

  - by Chris Paterson

  What does the '^' mean in the code below? @implementation AppController - (IBAction) loadComposition:(id)sender { void (^handler)(NSInteger); NSOpenPanel *panel = [NSOpenPanel openPanel]; [panel setAllowedFileTypes:[NSArray arrayWithObjects: @"qtz", nil]]; handler = ^(NSInteger result) { if (result == NSFileHandlingPanelOKButton) { NSString *filePath = [[[panel URLs] objectAtIndex:0] path]; if (![qcView loadCompositionFromFile:filePath]) { NSLog(@"Could not load composition"); } } }; [panel beginSheetModalForWindow:qcWindow completionHandler:handler]; } @end === I've searched and searched - is it some sort of particular reference to memory?

• Example where Up-Front Design (Would have) Saved You Time

  - by Winston Ewert

  In various places I've seen the claim that by designing a system up-front, you can significantly reduce development time. I.e. by spending an hour designing you can save a week coding. My problem is that I have never seen a situation where I found this to be true. So I want to know of any examples out there that people have where this would be true: So: What sort of problem arose during coding? (or was avoided?) How could you have avoided (or did avoid) the problem by spending more time doing design? Why was it (or would it have been) hard to fix the problem in the code?

• Understanding protocols

  - by kronicali

  Hi, guys need some insight here. I know the definition of a protocol, being new to this c++ programming is quite a challenging task.I am creating a Multi-threaded chat using SDL/C++, this is a learning experience for me and now i have encounter a hump in which I need to overcome but understanding it is a little more difficult than I had thought.I need to make a chat protocol of some sort, I think...but am stump. Up until this point i have been sending messages in strings of characters.Now that am improving the application to the point where clients can register and login, I need a better way to communicating with my clients and server. thank you.

• Ranged integers in .NET (or C#)

  - by Mal Ross

  Am I being blind, or does the .NET framework not provide any kind of ranged integer class? That is, a type that would prevent you setting a value outside some given bounds that are not the full range of the basic data type. For example, an integer type that would restrict its values to between 1 and 100. Showing my age here, but back in '93, I remember using that sort of thing in Modula-2 (eeek!), but I've not seen explicit framework / language support for it since. Am I just missing something, or is it a case of "it's so simple to make your own that the framework doesn't bother"? Cheers.

• Why are there performance differences when a SQL function is called from .Net app vs when the same c

  - by Dan Snell

  We are having a problem in our test and dev environments with a function that runs quite slowly at times when called from an .Net Application. When we call this function directly from management studio it works fine. Here are the differences when they are profiled: From the Application: CPU: 906 Reads: 61853 Writes: 0 Duration: 926 From SSMS: CPU: 15 Reads: 11243 Writes: 0 Duration: 31 Now we have determined that when we recompile the function the performance returns to what we are expecting and the performance profile when run from the application matches that of what we get when we run it from SSMS. It will start slowing down again at what appear to random intervals. We have not seen this in prod but they may be in part because everything is recompiled there on a weekly basis. So what might cause this sort of behavior?

• How to iterate through an XDocument's Nodes

  - by Ed R

  I am trying to iterate through my xml document's nodes to get the value for <username>Ed</username> in each node. I am using Linq to sort the XDocument first, then attempting to loop through the nodes. I can't seem to find the correct foreach loop to achieve this. Any help is appreciated. var doc = XDocument.Load("files\\config.xml"); var newDoc = new XDocument(new XElement("Config", from p in doc.Element("Config").Elements("Profile") orderby int.Parse(p.Element("order").Value) select p)); foreach (XElement xe in newDoc.Nodes()) { MessageBox.Show(xe.Element("username").Value); }

• Looking for a wiki-style, standalone, version-control-"safe" documenation package

  - by basszero

  This may sound like it's not a programming related question, but stick with me here... My team and I have found that documenting our project (a development platform w/ API) with a wiki is both useful to us and useful to the users. Due to some organizational issues, we're forced to do multi-site development without network connectivity. We've switched to a DVCS (Mercurial) and had great success with this. The wiki documentation proves to be a problem as the central site is setup with MediaWiki. The offsite people have no way to access or edit the wiki. Is there any sort of wiki-style package which doesn't not require a server/database and will be useable in a DVCS environment? Update: Should be open-source and cross-platform

• How to enforce a site-wide license?

  - by Roy Tang

  We have a small .Net program that we sell with individual licenses. The individual licenses are enforced by registering a key file that is generated using information from the machine used to install the program (MAC address, etc.) Now, we have a customer request for a site-wide license, such that they can deploy to as many machines on their site as possible. From the technical POV I'm not sure what are the usual approaches for this; our old approach won't work since we can't map the license to any machine-specific information. Any suggestions? A few more details: the program is a client-side program that includes an Office Add-In the machines to be installed on may or may not have internet access we aren't restricted to .Net-only approaches, I'm just looking for a general idea of how this sort of thing is usually handled

• Getting data from sharepoint into drupal

  - by andersandersson666

  The problem: I am about to develop a Drupal site for a company that stores a lot of data in a sharepoint environment (products, recipes etc...). I need to get that information into my Drupal system somehow. Preferably saving it as drupal nodes. That information will also be edited/added in the sharepoint system, so on top of just saving the data to drupal it will also have to check for updates on a regular basis. One idea for a solution is using some sort of web-service to retrieve data, but i have no idea of how that would be done in drupal. So my question(s) is: Has anyone done anything like this, if so how, or does anyone have any suggestions to how one would go about doing this? Any answers would be highly appreciated. /Anders

• Django: How do I go about changing my simple app to use Ajax?

  - by swisstony

  I currently have a web page where the user enters some data and then clicks a submit button. I process the data in views.py and then use the same Django template to return and display the original data and the results. What I would like to do is try to give it a bit more of a modern look and feel. You know the sort of thing, the page doesn't refresh but displays a spinning disk until the results are displayed. I assume this means using Ajax? How difficult is it to modify a simple app like this to use Ajax? What is involved? What are the best tools to use? JQuery?

• How do I output an individual character when using char *[] = "something"

  - by Matt

  I've been playing with pointers to better understand them and I came across something I think I should be able to do, but can't sort out how. The code below works fine - I can output "a", "dog", "socks", and "pants" - but what if I wanted to just output the 'o' from "socks"? How would I do that? char *mars[4] = { "a", "dog", "sock", "pants" }; for ( int counter = 0; counter < 4; counter++ ) { cout << mars[ counter ]; } Please forgive me if the question is answered somewhere - there are 30+ pages of C++ pointer related question, and I spent about 90 minutes looking through them, as well as reading various (very informative) articles, before deciding to ask.

• Searching within an array of strings...

  - by SoLoGHoST

  Ok, I'm feeling retarded here, I have a string like so: $string = 'function module_testing{'; or it could be like this: $string = 'function module_testing'; And than I have an array of strings like so: $string_array = array('module_testing', 'another_function', 'and_another_function'); Now, is there some sort of preg_match that I can do to test if any of the $string_array values are found within the $string string at any given position? So in this situation, there would be a match. Or is there a better way to do this? I can't use in_array since it's not an exact match, and I'd rather not do a foreach loop on it if I can help it, since it's already in a while loop. Thanks :)

• How do I view Visual Studio BuildLog.htm files without cutting and pasting into an external browser

  - by bgoodr

  This may or may not be specific to VS2005 (as that is the version I'm referring to for this question). I find often the case is that I see this in the Output panel inside Visual Studio 2>Build log was saved at "file://c:\\vsdll_example\MyExecRefsDll\Debug\BuildLog.htm" Now, since that looks and smells like a URL, I would have thought that I could simply left mouse click on it, or left mouse double-click on it, and a browser window of some sort would be displayed. No, that doesn't work. So, to view it, I have to cut and paste the "file://bla/bla/bla" part into an external window. Is there a way to set up Visual Studio to allow me to browse to that file directly, or view it inside Visual Studio IDE, or something to that effect, without the extra fiddling with cutting and pasting? Or is there some type of keybinding I'm not aware of? Thanks, bg

• In which controller do you put the CRUD for the child part of a relationship?

  - by uriDium

  I am using ASP.Net MVC but this probably applies to all MVC patterns in general. My problem, for example I have companies and in each company I have a list of contacts. When I have selected a company I can see its details and a list of the contacts for that company. When I want to add a new contact for that company, should the implementation of that action go into the company controller as an "AddContact" action or should it go into the contact controller into a "New" action and we pass the Company ID in the URL? What is the usual way of dealing with this sort of thing in ASP.Net MVC? Is there a better stategy?

• .net Compiler Optimizations

  - by Dested

  I am writing an application that I need to run at incredibly low speeds. The application creates and destroys memory in creative ways throughout its run, and it works just fine. I am wondering what compiler optimizations occur so I can try to build to that. One trick off hand is that the CLR handles arrays much faster than lists, so if you need to handle a ton of elements in a List, you may be better off calling ToArray() and handling it rather than calling ElementAt() again and again. I am wondering if there is any sort of comprehensive list for this kind of thing, or maybe the SO community can create one :-)

• PHPUnit test for error thrown with wrong argument type

  - by Spencer Mark

  I'm just starting with PHPUnit and am ok with all assert* methods, but can't figure out how to test for error thrown when the wrong argument is provided to the method - say hinted with array like so: public function(array $list) { } and then tested with null as argument. Could someone please provide an example of how to test for this sort of errors? I've checked quite a few posts on stackoverflow, but couldn't find the answer to this specific issue. Edit Ok - just to give you an idea of what I'm testing - here's the ArrayHelper::removeIfValueIsEmpty() method: public static function removeIfValueIsEmpty(array $array) { if (empty($array)) { return array(); } return array_filter($array, function($value) { return !Helper::isEmpty($value); }); } and now test: class ArrayHelperTest extends PHPUnit_Framework_TestCase { public function testRemoveIfValueIsEmpty() { $this->assertEmpty( \Cmd\Helper\ArrayHelper::removeIfValueIsEmpty(null), '\Cmd\Helper\ArrayHelper::removeIfValueIsEmpty method failed (checking with null as argument)' ); } } This throws an error: PHPUnit_Framework_Error : Argument 1 passed to Cmd\Helper\ArrayHelper::removeIfValueIsEmpty() must be of the type array, null given

• How to store Hierarchical K-Means tree for a large number of images, using Opencv?

  - by AquaAsh

  I am trying to make a program that will find similar images from a dataset of images. The steps are 1)extract SURF descriptors for all images 2)store the descriptors 3)Apply knn on the stored descriptors 4)Match the stored descriptors to the query image descriptor using KNN Now each images SURF descriptor will be stored as Hierarchical k means tree, now do I store each tree as a separate file or is it possible to build some sort of single tree with all the images descriptors and updated as images are added to dataset. This is the paper I am basing the program on www.ijest.info/docs/IJEST10-02-03-13.pdf.

• jQuery $.post & $.append & IE6

  - by Jim

  I'm having a weird problem with jQuery and IE6. Script works on IE7+ and with all other browsers I have tried it. I can't post the full script, but what it does is this: $.post("file.php",{'foo':'bar'},function(data){ $('#target').append(data) }) When I run the code in IE6, #target just shows ? and a white char with a hole in the middle. I have no idea what this second char is. My initial thought was that this was some sort of content-type problem because the file.php just echoes answer without any header information. I added Content-type: text/html with header() but didn't help. Any suggestions?
