  • C# start a static thread

    - by user595605
    I have a Queue of items I want to process in a thread, and any instance of a class can add items to the Queue to be processed. My idea for doing this is to have a static Thread in the class that processes the items, the only problem is that I don't know where to start this thread, since I can't start it in its initialization. Is there a way I can start a static thread? Or should I be changing the architecture completely?

  • Zyxel P-320W: How to connect to my web server using public IP

    - by hvtuananh
    My company's router is Zyxel P-320W and I have a public static IP. I registered a few domains name and point to this IP address. I already setup Virtual Hosts and configured port-forwarding to my internal server and it works well. I can connect to all domains from outside The problem is I cannot connect to my domains from inside One workaround way is modify hosts file to add internal IP for those domains, but my company have many computers and I don't want to setup all PC manually

  • Data Connection Library in SharePoint Server 2010

    - by Wayne
    What is a Data Connection Library in SharePoint Server 2010? A Data Connection Library in Microsoft SharePoint Server 2010 is a library that can contain two kinds of data connections: an Office Data Connection (ODC) file or a Universal Data Connection (UDC) file. Microsoft InfoPath 2010 uses data connections that comply with the Universal Data Connection (UDC) file schema and typically have either a *.udcx or *.xml file name extension. Data sources described by these data connections are stored on the server and can be used in standard form templates and browser-enabled form templates. How to create a SharePoint Server Data Connection Library? 1. Browse to a SharePoint Server 2010 site on which you have at least Design permissions. If you are on the root site, create a new site before you continue with the next step. 2. On the Site Actions menu, click More Options. 3. On the Create page, click Library under Filter By, and then click Data Connection Library. 4. On the right side of the Create page, type a name for the library, and then click the Create button. 5. Copy the URL of the new data connection library. How to create a new data connection file in InfoPath? 1. Open InfoPath Designer 2010, click Blank Form, and then click Design Form. 2. On the Data tab, click Data Connections, and then click Add. 3. In the Data Connection Wizard, click Create a new connection to, click Receive data, and then click Next. 4. Click the kind of data source that you are connecting to, such as Database, Web service, or SharePoint library or list, and then click Next. 5. Complete the remaining steps in the Data Connection Wizard to configure your data connection, and then click Finish to return to the Data Connections dialog box. 6. In the Data Connections dialog box, click Convert to Connection File. 7. In the Convert Data Connection dialog box, enter the URL of the data connection library that you previously copied (delete "Forms/AllItems.aspx" and anything following it from the URL), enter a name for the data connection file at the end of the URL, and then click OK. It will take a few moments to convert and save the data connection file to the library. 8. Confirm that the data connection was converted successfully by examining the Details section of the Data Connections dialog box while the name of the converted data connection is selected. 9. Browse to the SharePoint data connection library, click the drop-down next to the name of the data connection, click Approve/Reject, click Approved, and then click OK. Take advantage of SharePoint Data Connection Library and other useful features of SharePoint family of products that include, SharePoint Foundation 2010, MOSS 2007 and free SharePoint templates or web parts.

  • How do I set a static DNS nameserver address on Ubuntu Server?

    - by Aleks
    I am trying statically to set DNS server addresses in my Ubuntu server running as virtual machine. I followed all recommendations on official Ubuntu support pages but I simply cannot get rid of my ISP's DNS servers set by DHCP. I assigned br0 interface on my host machine static IP address and eth0 on VM to use Google DNS and my own local DNS running on the second vm by setting it in /etc/network/interfaces. Tried to fiddle with head base and tail files in /etc/resolvconf/resolv.conf.d/ and tried to shuffle interface-order in /etc/resolvconf/interface-order but when I restarted network service I got the ISP's DNS addresses back every time. Is there a way that I can disable resolvconf and set up my resolv.conf file manually as I always did on Red Hat? Or at can you tell me which hook script keeps putting ISP DNSs in resolv.conf? My ISP don't allow me to change DHCP settings on my router so I cannot do it that way. Why is such a simple thing such as setting DNS servers got so complicated???

  • Can static and dynamically typed languages be seen as different tools for different types of jobs?

    - by Erik Reppen
    Yes, similar questions have been asked but always with the aim of finding out 'which one is better.' I'm asking because I came up as a dev primarily in JavaScript and don't really have any extensive experience writing in statically typed languages. In spite of this I definitely see value in learning C for handling demanding operations at lower levels of code (which I assume has a lot to do with static vs dynamic at the compiler level), but what I'm trying to wrap my head around is whether there are specific project contexts (maybe certain types of dynamic data-intensive operations?) involving things other than performance where it makes a lot more sense to go with Java or C# vs. something like Python.

  • What is the impact of a CMS on page load time versus a static site?

    - by PleaseStand
    I am creating a 20-page site that will go on shared hosting. Each page will be about 20 KB (including HTML, CSS, and images common to all pages). To avoid manually adding navigation elements to each page, I am considering using a CMS. However, I am concerned that on a busy server, using a CMS would make the site load more slowly. In a shared hosting environment where PHP is run as a CGI binary, how much does a CMS (WordPress, Drupal, etc.) generally affect page load time, compared to both "plain HTML" static sites and those using PHP as merely a templating language?

  • Resource not found using library project in Android

    - by hgpc
    I'm converting an existing project into a library project. I configured the original project as a library project and added an application project which references the original project as a library. The library project has an activity (MainActivity) and its layout (main.xml). The application project declares this activity as the main activity in the manifest like this: <activity android:name="com.example.MainActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> When I run the application project I get the following error... android.content.res.Resources$NotFoundException: Resource ID #0x7f030002 ...on the following line of the onCreate method of the main activity: setContentView(R.layout.main); 0x7f030002 is the ID of R.layout.main in the library project. The application project has no main resource. If I run the original project I don't get this error. Both projects neither have compilation errors nor warnings and are built with Android 2.2 with min SDK version 3. What might be the problem?

  • iPhone SDK linking errors with static library

    - by Nico
    Hello all! I've built my own static library with components to be reused in my project, and recently had the need to update a bunch of classes. Specifically, some methods' signatures were changed due to the fact that some classes changed names. What happens now is that the library compiles fine on its own, but, when added to an app project, the project fails to link: Ld build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales normal armv6 cd /Users/nameghino/src/Sucursales setenv IPHONEOS_DEPLOYMENT_TARGET 3.1 setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -L/Users/nameghino/src/Sucursales/build/Debug-iphoneos -L/Users/nameghino/src/Sucursales/../../Library/MyLibraries/MSSharedLibrary-1.0.0 -F/Users/nameghino/src/Sucursales/build/Debug-iphoneos -filelist /Users/nameghino/src/Sucursales/build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales.LinkFileList -dead_strip -lxml2 -ObjC -all_load -miphoneos-version-min=3.1 -framework Foundation -framework UIKit -framework CoreGraphics -lsqlite3.0 -framework CoreLocation -framework MapKit -lxml2 /Users/nameghino/src/MSSharedComponents/Frameworks/MSSharedLibrary/build/Debug-iphoneos/libMSSharedLibrary.a -o /Users/nameghino/src/Sucursales/build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales Undefined symbols: "_OBJC_CLASS_$_DataCatalogService_GetSingleRow", referenced from: objc-class-ref-to-DataCatalogService_GetSingleRow in libMSSharedLibrary.a(MSDataCatalogSpecification.o) **"_OBJC_CLASS_$_DataCatalogService_ArrayOfString", referenced from: objc-class-ref-to-DataCatalogService_ArrayOfString in libMSSharedLibrary.a(MSDataCatalogSpecification.o) "_OBJC_CLASS_$_DataCatalogService_GetSingleRowResponse", referenced from: objc-class-ref-to-DataCatalogService_GetSingleRowResponse in libMSSharedLibrary.a(MSSingleRowResultsParser.o) "_OBJC_CLASS_$_DataCatalogService_GetMultiRowResponse", referenced from: objc-class-ref-to-DataCatalogService_GetMultiRowResponse in libMSSharedLibrary.a(MSMultiRowResultsParser.o) "_OBJC_CLASS_$_DataCatalogService_GetMultiRow", referenced from: objc-class-ref-to-DataCatalogService_GetMultiRow in libMSSharedLibrary.a(MSDataCatalogSpecification.o) "_OBJC_CLASS_$_DataCatalogService_HelloWorldResponse", referenced from: objc-class-ref-to-DataCatalogService_HelloWorldResponse in libMSSharedLibrary.a(DataCatalogService.o) ld: symbol(s) not found collect2: ld returned 1 exit status** The curious thing is that after a lot of project cleanups (both in the app and the lib projects), I still get the same issue.

  • Using Fancybox with Google Static Maps

    - by Levi Hackwith
    Setup I have multiple links on a page with the class location_link Each Links rel attribute is equal to a city state combo (i.e.,Omaha, NE) Once the page is loaded, a JavaScript function loops through all of the location_link items and binds a click event to them using jQuery. This click event fires a call to the Fancybox constructor that is supposed to show a Google Map of the location that link is associated with The Problem: Whenever I click on one of the "location links", I get the following error message: The requested content cannot be loaded. Please try again later. Code I've Already Written: function setUpLocationLinks() { locationLinks = $("a.location_link"); locationLinks.click( function() { var me = $(this); console.log(me.attr("href")); $.fancybox( { "showCloseButton" : true, "hideOnContentClick" : true, "titlePosition" : "inside", "title" : me.attr("rel"), "type" : "image" } ) return false; } ); } Research I've Already Done: The Google Static Map API no longer requires an API Key. The following is from the Google Static Maps API Page Note: The Google Static Maps API no longer requires a Maps API key! (Google Maps API Premier customers should instead sign their URLs using a new cryptographic key which will be sent to you. See the Premier documentation for more information.) The The Image URL I'm using does resolve and pulls back the data I need When I put the above mentioned URL into a standard <img> tag, the map shows up just fine. I'd like to pull this off without having to create some sort of dummy <img> tag that I'm constantly switching the src attribute out of. Hopefully, you'll find this information helpful. Please let me know if you have any other questions.

  • Static IP for dynamic IP

    - by scape279
    I have a dynamic IP address. I would like to have a static IP, but Virgin Media don't allow static IPs for residential broadband services, even if you ask them really nicely and offer to pay for it without switching to a business tariff. I am already registered with a dynamic DNS service which is updated by my router eg me.example.com will always resolve to my dynamic IP. This is fine for some circumstances, but not if you can only enter an IP address into configuration files/hardware etc like firewalls, subversion services etc etc. Is there a way I can have a static IP address 'forwarding' to my dynamic IP? Would a possible solution involve tunnelling? Setting up a private proxy? Please note the following: I am able to buy an IP address from my web host. I have access to a webserver and I am able to create custom DNS zones. I'm happy to have a webserver running at home if necessary also. I do not wish to change broadband providers. I have zero control over the services that require the IP address entering so I cannot tackle the problem that way round (services I need to access are at work). PS I've tried googling this issue, but it is very difficult to search for as most results are related to dynamic dns (which I already have set up and isnt quite what I'm after)

  • Using Unit Tests While Developing Static Libraries in Obj-C

    - by macinjosh
    I'm developing a static library in Obj-C for a CocoaTouch project. I've added unit testing to my Xcode project by using the built in OCUnit framework. I can run tests successfully upon building the project and everything looks good. However I'm a little confused about something. Part of what the static library does is to connect to a URL and download the resource there. I constructed a test case that invokes the method that creates a connection and ensures the connection is successful. However when my tests run a connection is never made to my testing web server (where the connection is set to go). It seems my code is not actually being ran when the tests happen? Also, I am doing some NSLog calls in the unit tests and the code they run, but I never see those. I'm new to unit testing so I'm obviously not fully grasping what is going on here. Can anyone help me out here? P.S. By the way these are "Logical Tests" as Apple calls them so they are not linked against the library, instead the implementation files are included in the testing target.

  • Face recognition Library

    - by Janusz
    I'm looking for a free face recognition library for a university project. I'm not looking for face detection. I'm looking for actual recognition. That means finding images that contain specified faces or libraries that calculate distances between specific faces. I'm using OpenCV for detecting the faces and a rough Eigenfaces Algorithm for the recognition now. But I thought there should be something out there with a better performance then a self written Eigenfaces Algorithm. I don't talk about speed as performance I'm looking for a library with better results as an simple Eigenfaces approach I took a look at faint but it seems the library is not very reusable for my own applications. I'm happy with a library in Python, Java, C++, C or something like that. The best thing would be if it can be run on a Windowsmachine

  • Static Data Structures on Embedded Devices (Android in particular)

    - by Mark
    I've started working on some Android applications and have a question regarding how people normally deal with situations where you have a static data set and have an application where that data is needed in memory as one of the standard java collections or as an array. In my current specific issue i have a spreadsheet with some pre-calculated data. It consists of ~100 rows and 3 columns. 1 Column is a string, 1 column is a float, 1 column is an integer. I need access to this data as an array in java. It seems like i could: 1) Encode in XML - This would be cpu intensive to decode in my experience. 2) build into SQLite database - seems like a lot of overhead for static access to data i only need array style access to in ram. 3) Build into binary blob and read in. (never done this in java, i miss void *) 4) Build a python script to take the CSV version of my data and spit out a java function that adds the values to my desired structure with hard coded values. 5) Store a string array via androids resource mechanism and compute the other 2 columns on application load. In my case the computation would require a lot of calls to Math.log, Math.pow and Math.floor which i'd rather not have to do for load time and battery usage reasons. I mostly work in low power embedded applications in C and as such #4 is what i'm used to doing in these situations. It just seems like it should be far easier to gain access to static data structures in java/android. Perhaps I'm just being too battery usage conscious and in my single case i imagine the answer is that it doesn't matter much, but if every application took that stance it could begin to matter. What approaches do people usually take in this situation? Anything I missed?

  • A C# app that references a C# dll which uses Enterprise Library is throwing an error

    - by Matt
    I have a C# app that references another C# dll which in turn uses Enterprise Library. Because my app has no config xml file for setting the Enterprise Library settings, it is throwing an error, specifically: "The configuration section for Logging cannot be found in the configuration source." "Microsoft.Practices.EnterpriseLibrary.Logging" I would rather not add an XML config file to my app to just turn off Enterprise Library. Is there a code way to do so in my the source for my app?

  • Variant datatype library for C

    - by Joey Adams
    Is there a decent open-source C library for storing and manipulating dynamically-typed variables (a.k.a. variants)? I'm primarily interested in atomic values (int8, int16, int32, uint, strings, blobs, etc.), while JSON-style arrays and objects as well as custom objects would also be nice. A major case where such a library would be useful is in working with SQL databases. The most obvious feature of such a library would be a single type for all supported values, e.g.: struct Variant { enum Type type; union { int8_t int8_; int16_t int16_; // ... }; }; Other features might include converting Variant objects to/from C structures (using a binding table), converting values to/from strings, and integration with an existing database library such as SQLite. Note: I do not believe this is question is a duplicate of http://stackoverflow.com/questions/649649/any-library-for-generic-datatypes-in-c , which refers to "queues, trees, maps, lists". What I'm talking about focuses more on making working with SQL databases roughly as smooth as working with them in interpreted languages.

  • Configure IIS7 to server static content through ASP.NET Runtime

    - by Anton Gogolev
    I searched high an low and still cannot find a definite answer. How do I configure IIS 7.0 or a Web Application in IIS so that ASP.NET Runtime will handle all requests -- including ones to static files like *.js, *.gif, etc? What I'm trying to do is as follows. We have kind of SaaSy site, which we can "skin" for every customer. "Skinnig" means developing a custom master page and using a bunch of *.css and other images. Quite naturally, I'm using VirtualPathProvider, which operates like this: public override System.Web.Hosting.VirtualFile GetFile(string virtualPath) { if(PhysicalFileExists(virtualPath)) { var virtualFile = base.GetFile(virtualPath); return virtualFile; } if(VirtualFileExists(virtualPath)) { var brandedVirtualPath = GetBrandedVirtualPath(virtualPath); var absolutePath = HttpContext.Current.Server.MapPath(brandedVirtualPath); Trace.WriteLine(string.Format("Serving '{0}' from '{1}'", brandedVirtualPath, absolutePath), "BrandingAwareVirtualPathProvider"); var virtualFile = new VirtualFile(brandedVirtualPath, absolutePath); return virtualFile; } return null; } The basic idea is as follows: we have a branding folder inside our webapp, which in turn contains folders for each "brand", with "brand" being equal to host name. That is, requests to http://foo.example.com/ should use static files from branding/foo_example_com, whereas http://bar.example.com/ should use content from branding/bar_example_com. Now what I want IIS to do is to forward all requests to static files to StaticFileHandler, which would then use this whole "infrastructure" and serve correct files. However, try as I might, I cannot configure IIS to do this.

  • How to add dependencies to 3rd party library using nexus/maven

    - by ssaboum
    Hi everyone, i'm trying to use Nexus + m2eclipse/maven-3 professionnally, and i've got a huge 3rd party library that needs a lot of dependencies. Is there any ways to ease my pain by uploading to Nexus this third party library with all its dependencies linked, so that anyone who would need it would just have to add the maven-dependency-tag only for this huge library ? Do i need to create the pom myself ? thank you for your help.

  • Static variable for communication among like-typed objects

    - by Dan Ray
    I have a method that asynchronously downloads images. If the images are related to an array of objects (a common use-case in the app I'm building), I want to cache them. The idea is, I pass in an index number (based on the indexPath.row of the table I'm making by way through), and I stash the image in a static NSMutableArray, keyed on the row of the table I'm dealing with. Thusly: @implementation ImageDownloader ... @synthesize cacheIndex; static NSMutableArray *imageCache; -(void)startDownloadWithImageView:(UIImageView *)imageView andImageURL:(NSURL *)url withCacheIndex:(NSInteger)index { self.theImageView = imageView; self.cacheIndex = index; NSLog(@"Called to download %@ for imageview %@", url, self.theImageView); if ([imageCache objectAtIndex:index]) { NSLog(@"We have this image cached--using that instead"); self.theImageView.image = [imageCache objectAtIndex:index]; return; } self.activeDownload = [NSMutableData data]; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:[NSURLRequest requestWithURL:url] delegate:self]; self.imageConnection = conn; [conn release]; } //build up the incoming data in self.activeDownload with calls to didReceiveData... - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"Finished downloading."); UIImage *image = [[UIImage alloc] initWithData:self.activeDownload]; self.theImageView.image = image; NSLog(@"Caching %@ for %d", self.theImageView.image, self.cacheIndex); [imageCache insertObject:image atIndex:self.cacheIndex]; NSLog(@"Cache now has %d items", [imageCache count]); [image release]; } My index is getting through okay, I can see that by my NSLog output. But even after my insertObject: atIndex: call, [imageCache count] never leaves zero. This is my first foray into static variables, so I presume I'm doing something wrong. (The above code is heavily pruned to show only the main thing of what's going on, so bear that in mind as you look at it.)

  • PHP: Get instance of static class by string value

    - by Tirithen
    I'm working on a php web api that was handed to me with a lot of code that needs to be refactored. The ones that wrote the code wanted to include a static configuration class to an api resource and then get an instance of that class something like this: <?php $obj = "User"; $confObjectSuffix = "_conf"; $confObject = $obj.$confObjectSuffix; if ($confObject::inst()->checkMethod($method)) { ..... This gives the error "Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in ....." since $confObject is a string and not a object. I wrote some testcode: <?php $class = "User_conf"; echo "<pre>"; print_r($$class::Inst()); echo "</pre>"; class User_conf { private static $INSTANCE = null; public static function Inst() { if(User_conf::$INSTANCE === null) { User_conf::$INSTANCE = new User_conf(); } return User_conf::$INSTANCE; } } But can't get it to work with $$ either, is there some other way around this? I don't want to rewrite more than necessary.
