  • ipconfig /release not working, why?

    - by barlop
    ipconfig /release is not working, why is that? here is a sequence where I put my cable in get an IP, try ipconfig /release and it tells me it can't release wireless, but there is no wireless connection. i'm just trying to release the wired one. C:\>ipconfig Windows IP Configuration Ethernet adapter Wireless Network Connection: Media State . . . . . . . . . . . : Media disconnected Ethernet adapter Local Area Connection: Media State . . . . . . . . . . . : Media disconnected Fine so I plug my cable in C:\>ipconfig Windows IP Configuration Ethernet adapter Wireless Network Connection: Media State . . . . . . . . . . . : Media disconnected Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 0.0.0.0 Subnet Mask . . . . . . . . . . . : 0.0.0.0 Default Gateway . . . . . . . . . : C:\>ipconfig Windows IP Configuration Ethernet adapter Wireless Network Connection: Media State . . . . . . . . . . . : Media disconnected Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 192.168.1.8 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.254 Fine so from above, it clearly has an iP C:\>ipconfig /release Windows IP Configuration No operation can be performed on Wireless Network Connection while it has its me dia disconnected.

  • Multi-threaded library calls in ASP.NET page request.

    - by ProfK
    I have an ASP.NET app, very basic, but right now too much code to post if we're lucky and I don't have to. We have a class called ReportGenerator. On a button click, method GenerateReports is called. It makes an async call to InternalGenerateReports using ThreadPool.QueueUserWorkItem and returns, ending the ASP.NET response. It doesn't provide any completion callback or anything. InternalGenerateReports creates and maintains five threads in the threadpool, one report per thread, also using QueueUserWorkItem, by 'creating' five threads, also with and waiting until calls on all of them complete, in a loop. Each thread uses an ASP.NET ReportViewer control to render a report to HTML. That is, for 200 reports, InternalGenerateReports should create 5 threads 40 times. As threads complete, report data is queued, and when all five have completed, report data is flushed to disk. My biggest problems are that after running for just one report, the aspnet process is 'hung', and also that at around 200 reports, the app just hangs. I just simplified this code to run in a single thread, and this works fine. Before we get into details like my code, is there anything obvious in the above scendario that might be wrong?

  • Which format does static library (*.lib) files use? Where can I find "Official" specifications of *.

    - by claws
    Just now I found that static libraries in *nix systems, in other words *.a libraries are nothing but archives of relocatables(*.o files) in ar fromat. What about static libraries(*.lib files) in windows? Which format are they in? I found an article: http://www.microsoft.com/msj/0498/hood0498.aspx which explains *.lib file structure. But Where can I find "Official" specifications of *.lib file structure/format? Other than ar.exe of mingw is there any tool from Microsoft which extracts relocatable objects of *.lib & *.a files? EDIT: I wonder why I'm unable to get to this question. If there are no official specifications. Then how does the compiler ('linker' to be more correct) writers work with *.LIB files?

  • Is there a JQuery equivalent class/library in PHP?

    - by DKinzer
    Soon I'll be working on a batch script where I will need to make some changes to some HTML files. I know that I can use DOMDocument and DOMXPath to manipulate these files. But, I really love JQuery. It would be great if there was something a lot more like JQuery in the PHP world. Does anybody know if something like that exists? Thanks! D

  • How to solve generic algebra using solver/library programmatically? Matlab, Mathematica, Wolfram etc?

    - by DevDevDev
    I'm trying to build an algebra trainer for students. I want to construct a representative problem, define constraints and relationships on the parameters, and then generate a bunch of Latex formatted problems from the representation. As an example: A specific question might be: If y < 0 and (x+3)(y-5) = 0, what is x? Answer (x = -3) I would like to encode this as a Latex formatted problem like. If $y<0$ and $(x+constant_1)(y+constant_2)=0$ what is the value of x? Answer = -constant_1 And plug into my problem solver constant_1 > 0, constant_1 < 60, constant_1 = INTEGER constant_2 < 0, constant_2 > -60, constant_2 = INTEGER Then it will randomly construct me pairs of (constant_1, constant_2) that I can feed into my Latex generator. Obviously this is an extremely simple example with no real "solving" but hopefully it gets the point across. Things I'm looking for ideally in priority order * Solve algebra problems * Definition of relationships relatively straight forward * Rich support for latex formatting (not just writing encoded strings) Thanks!

    I am getting this error: SyntaxError: hello.rb:13: syntax error, unexpected tIDENTIFIER public HelloWorld( InputStream data ) throws IOException { The HelloWorld.rb is: require "java" import java.io.FileInputStream; import java.io.InputStream; import java.io.IOException; import opennlp.tools.postag.POSModel; import opennlp.tools.postag.POSTaggerME; public class HelloWorld { private POSModel model; public HelloWorld( InputStream data ) throws IOException { setModel( new POSModel( data ) ); } public void run( String sentence ) { POSTaggerME tagger = new POSTaggerME( getModel() ); String[] words = sentence.split( "\\s+" ); String[] tags = tagger.tag( words ); double[] probs = tagger.probs(); for( int i = 0; i < tags.length; i++ ) { System.out.println( words[i] + " => " + tags[i] + " @ " + probs[i] ); } } private void setModel( POSModel model ) { this.model = model; } private POSModel getModel() { return this.model; } public static void main( String args[] ) throws IOException { if( args.length < 2 ) { System.out.println( "HelloWord <file> \"sentence to tag\"" ); return; } InputStream is = new FileInputStream( args[0] ); HelloWorld hw = new HelloWorld( is ); is.close(); hw.run( args[1] ); } } when running ruby HelloWorld.rb "I am trying to make it work" when I run the HelloWorld.java "I am trying to make it work" it works perfectly, of course the .java doesn't contain the require java statement.

  • How to get a product key token from a library file programatically?

    - by jhorton
    I am creating a SharePoint solution project that will install the Telerik dll files into the GAC and write the appropriate lines into the webconfig upon feature activation. My question is, is there a way to get the product key token, version, and culture info of a dll programatically. I have used the System.Reflection.Assembly.GetExecutingAssembly() before to get the embedded resources, such as a javascript file, and add it to the appropriate folder. Would this be the same way to get the dll file, and if so what would I do to get the assembly info of an embedded assembly? Thanks for any direction.

  • A PHP Library / Class to Count Words in Various Languages?

    - by Michael Robinson
    Some time in the near future I will need to implement a cross-language word count, or if that is not possible, a cross-language character count. I'd love it if I just had to look at English, but I need to consider every language here, Chinese, Korean, English, Arabic, Hindi, and so on. I would like to know if Stack Overflow has any leads on where to start looking for an existing product / method to do this in PHP, as I am a good lazy programmer* *http://blogoscoped.com/archive/2005-08-24-n14.html

  • Ubuntu 9.04: Ripping CDs with grip?

    - by chris
    I tried to rip a CD tonight, and couldn't figure out how to configure grip - /dev/cdrom doesn't seem to be the mount point for music CDs any more. How can I configure grip to find CDs? Update: /etc/fstab has /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 But there's nothing visible in /media/cdrom0 (or /media/cdrom, which is a symlink to cdrom0) There's an icon on the desktop labeled "Audio Disk" and opening it shows the .wav files on the CD. The location is cdda://sr0/, but grip doesn't like that either. Trying to manually mount /dev/sr0, I get $ sudo mount -t auto /dev/sr0 foo/ mount: block device /dev/sr0 is write-protected, mounting read-only mount: you must specify the filesystem type Update 2: Tried to change the media handling preferences (From a file browser, Edit-Preferences, Media, CD Audio) to "Do Nothing". CD Still doesn't mount. Update 3: With an audio CD in the drive: $ ls -l /dev/ | grep cd lrwxrwxrwx 1 root root 3 2009-09-15 22:13 cdrom1 -> sr0 lrwxrwxrwx 1 root root 3 2009-09-15 22:13 cdrw1 -> sr0 drwxr-xr-x 2 root root 60 2009-09-15 22:13 pktcdvd lrwxrwxrwx 1 root root 3 2009-09-15 22:13 scd0 -> sr0 crw-rw----+ 1 root cdrom 21, 2 2009-09-15 22:13 sg2 brw-rw----+ 1 root cdrom 11, 0 2009-09-15 22:13 sr0

  • How to load an RSA key from binary data to an RSA structure using the OpenSSL C Library?

    - by Andreas Bonini
    Currently I have my private key saved in a file, private.key, and I use the following function to load it: RSA *r = PEM_read_RSAPrivateKey("private.key", NULL, NULL, NULL); This works perfectly but I'm not happy with the file-based format; I want to save my key in pure binary form (ie, no base64 or similar) in a char* variable and load/save the key from/to it. This way I have much more freedom: I'll be able to store the key directly into the application const char key[] { 0x01, 0x02, ... };, send it over a network socket, etc. Unfortunately though I haven't found a way to do that. The only way to save and load a key I know of reads/saves it to a file directly.

  • Sanitize HTML before storing in the DB or before rendering? (AntiXSS library in ASP.NET)

    - by user102533
    I have an editor that lets users add HTML that is stored in the database and rendered on a web page. Since this is untrusted input, I plan to use Microsoft.Security.Application.AntiXsSS.GetSafeHtmlFragment to sanitize the HTML. Should I santiize before saving to the database or before rendering the untrusted input into the webpage? Is there an advantage in including the AntiXSS source code in my project instead of just the DLL? (Maybe I can customize the white list?) Which class file should I look in for actual implementation of the GetSafeHtmlFragment

  • Could InAppSettingsKit do this, or is there another library?

    - by cannyboy
    I'm trying to implement a system whereby the user is initially presented with a single tablecell, in a uitableview (grouped style), within a uinavigationview. --------------- + | add record | --------------- When they click on the cell, they are pushed onto a new screen where they fill in a few textviews (perhaps imbedded in a tableview's cells) --------------- | (name) | --------------- | (phone num) | --------------- Then when they go back, they can see the new record as well as the 'add record' cell. --------------- | record 1 | --------------- + | add record | --------------- (When they go into record 1 again there would be a delete button) Is there any sample code or libraries which would achieve this? What about InAppSettingsKit? It's more the presentation I'm concerned with. I can handle the saving of data myself.

  • How Can I Find a List of All Exceptions That a Given Library Function Throws in Python?

    - by b14ck
    Sorry for the long title, but it seems most descriptive for my question. Basically, I'm having a difficult time finding exception information in the official python documentation. For example, in one program I'm currently writing, I'm using the shutil libary's move function: from shutil import move move('somefile.txt', '/tmp/somefile.txt') That works fine, as long as I have write access to /tmp/, there is enough diskspace, and if all other requirements are satisfied. However, when writing generic code, it is often difficult to guarantee those factors, so one usually uses exceptions: from shutil import move try: move('somefile.txt', '/tmp/somefile.txt') except: print 'Move failed for some reason.' I'd like to actually catch the appropriate exceptions thrown instead of just catching everything, but I simply can't find a list of exceptions thrown for most python modules. Is there a way for me to see which exceptions a given function can throw, and why? This way I can make appropriate cases for each exception, eg: from shutil import move try: move('somefile.txt', '/tmp/somefile.txt') except PermissionDenied: print 'No permission.' except DestinationDoesNotExist: print "/tmp/ doesn't exist" except NoDiskSpace: print 'No diskspace available.' Answer points go to whoever can either link me to some relevant documentation that I've somehow overlooked in the official docs, or provide a sure-fire way to figure out exactly which exceptions are thrown by which functions, and why. Thanks!

  • Can we you the attached properties in C# class library?

    - by Manas Agarwal
    Hi I have implemented the Observer Pattern with lazy load. The class that requests the data from the database is a singleton class. Now I am able to load the data from one database (located in one datacenter) very easily. But I need to get the data from other data centers too and display on the same UI. I can somehow pass the address of second data center and fetch the data from there also. But once I will get the data from second data center, it will be added to earlier list only. So later it will be thought for me to distinguish between the data. So I thought of attaching a property with the result set, so that while displaying the output I can show the data for both the data centers separately but on the same UI. I thought of attached property as an option where I can attach the data center name with the list of the data obtained. How is it possible to do in C#? Thanks Manas

  • Is it possible for two VS2008 C# class library projects to share a single namespace?

    - by jeah
    I am trying to share a common namespace between two projects in a single solution. The projects are "Blueprint" and "Repositories". Blueprint contains Interfaces for the entire application and serves as a reference for the application structure. In the Blueprint project, I have an interface with the following declaration: namespace Application.Repositories{ public interface IRepository{ IEntity Get(Guid id); } } In the Repositories project I have a class the following class: namespace Application.Repositories{ public class STDRepository: IRepository { STD Get(Guid id){ return new SkankyExGirlfriendDataContext() .FirstOrDefault<STD>(x=>x.DiseaseId == id); } } } However, this does not work. The Repositories project has a reference to the Blueprint project. I receive a VS error: "The type or namespace name 'IRepository' could not be found (are you missing a using directive or an assembly reference?) - Normally, this is easy to fix but adding a using statement doesn't make sense since they have the same namespace. I tried it anyway and it didn't work. The reference has been added, and without the line of code referencing that interface, both projects compile successfully. I am lost here. I have searched all over and have found nothing, so I am assuming that there is something fundamentally wrong with what I'm doing ... but I don't know what it is. So, I would appreciate some explanation or guidance as to how to fix this problem. I hope you guys can help. Note: The reason I want to do it this way and keep the interfaces under the same namespace is because I want a solid project to keep all the interfaces in, in order to have a reference for the full architecture of the application. I have considered work arounds, such as putting all of the interfaces in the Blueprint.Application namespace instead of the application namespace. However, that would require me to write the using statement on virtually every page in the application...and my fingers get tired. Thanks again guys...

  • Is rsync --delete safe in case of disk failure

    - by enedene
    I have two data hard drives on my Linux server and I use second as a backup for a first drive. I use rsync for that purpose. An example would be: rsync -r -v --delete /media/disk1/ /media/disk2/ What this does is that it copies every file/directory from /media/disk1/ to /media/disk2/ but also deletes any difference. For example, lets say that files A and B but not file C are on disk1, and on disk2 there is no A and B files, but there is C. The result would be that after the command on disk2 I'd have files A and B, but file C would be deleted, just like on disk1. Now, a rather disastrous scenario had crossed my mind; what if disk1 dies, system continues to work since system files are on my system disk, but when rsync tries to backup my data on disk2 from broken disk1, it deletes all the files from disk2 because it can't read anything on disk1. Is this a possible scenario, or is there a protection from it build in rsync?
