  • MVC Html.ActionLink with post funtionality?

    - by Levitikon
    I'm checking to see if anyone has written an MVC extension for Html.ActionLink that you can pass in Post parameters like such: <% Html.ActionLink("Click me", "Index", "Home", new { MyRouteValue = "123" }, null, new { postParam1 = "a", postParam2 = "b" }); %> That would render the link like normal but having an onClick event that submits an also rendered form with an Action url for the Action, Controller, and Route Values with additional hidden inputs from the Post Parameters like such: <a href="#" onClick="$('#theform').submit(); return false;">Click me</a> <form id="theform" action="/Home/Index/123" method="post"> <input type="hidden" name="postParam1" value="a"> <input type="hidden" name="postParam2" value="b"> </form> I'm looking to redirect users to various pages with potentially a lot of data. Not only from page to page, but from email to page also. This would be highly reusable and I think would clean up a lot of code, and would save a bunch of time writing this if its already floating around out there. I hate recreating the wheel when I don't have to. Thanks!

  • How do I alias the scala setter method 'myvar_$eq(myval)' to something more pleasing when in java?

    - by feydr
    I've been converting some code from java to scala lately trying to teach myself the language. Suppose we have this scala class: class Person() { var name:String = "joebob" } Now I want to access it from java so I can't use dot-notation like I would if I was in scala. So I can get my var's contents by issuing: person = Person.new(); System.out.println(person.name()); and set it via: person = Person.new(); person.name_$eq("sallysue"); System.out.println(person.name()); This holds true cause our Person Class looks like this in javap: Compiled from "Person.scala" public class Person extends java.lang.Object implements scala.ScalaObject{ public Person(); public void name_$eq(java.lang.String); public java.lang.String name(); public int $tag() throws java.rmi.RemoteException; } Yes, I could write my own getters/setters but I hate filling classes up with that and it doesn't make a ton of sense considering I already have them -- I just want to alias the _$eq method better. (This actually gets worse when you are dealing with stuff like antlr because then you have to escape it and it ends up looking like person.name_\$eq("newname"); Note: I'd much rather have to put up with this rather than fill my classes with more setter methods. So what would you do in this situation?

  • Using different numeric variable types

    - by DataPimp
    Im still pretty new so bear with me on this one, my question(s) are not meant to be argumentative or petty but during some reading something struck me as odd. Im under the assumption that when computers were slow and memory was expensive using the correct variable type was much more of a necessity than it is today. Now that memory is a bit easier to come by people seem to have relaxed a bit. For example, you see this sample code everywhere: for (int i = 0; i < length; i++) int? (-2,147,483,648 to 2,147,483,648) for length? Isnt byte (0-255) a better choice? So Im curious of your opinion and what you believe to be best practice, I hate to think this would be used only because the acronym "int" is more intuitive for a beginner...or has memory just become so cheap that we really dont need to concern ourselves with such petty things and therefore we should just use long so we can be sure any other numbers/types(within reason) used can be cast automagically? ...or am Im just being silly by concerning myself with such things?

  • Where does the delete control go in my Cocoa user interface?

    - by Graham Lee
    Hi, I have a Cocoa application managing a collection of objects. The collection is presented in an NSCollectionView, with a "new object" button nearby so users can add to the collection. Of course, I know that having a "delete object" button next to that button would be dangerous, because people might accidentally knock it when they mean to create something. I don't like having "are you sure you want to..." dialogues, so I dispensed with the "delete object". There's a menu item under Edit for removing an object, and you can hit Cmd-backspace to do the same. The app supports undoing delete actions. Now I'm getting support emails ranging from "does it have to be so hard to delete things" to "why can't I delete objects?". That suggests I've made it a bit too hard, so what's the happy middle ground? I see applications from Apple that do it my way, or with the add/remove buttons next to each other, but I hate that latter option. Is there another good (and preferably common) convention for delete controls? I thought about an action menu but I don't think I have any other actions that would go in it, rendering the menu a bit thin.

  • c++ specialized overload?

    - by acidzombie24
    -edit- i am trying to close the question. i solved the problem with boost::is_base_and_derived In my class i want to do two things. 1) Copy int, floats and other normal values 2) Copy structs that supply a special copy function (template T copyAs(); } the struct MUST NOT return int's unless i explicitly say ints. I do not want the programmer mistaking the mistake by doing int a = thatClass; -edit- someone mention classes dont return anything, i mean using the operator Type() overload. How do i create my copy operator in such a way i can copy both 1) ints, floats etc and the the struct restricted in the way i mention in 2). i tried doing template <class T2> T operator = (const T2& v); which would cover my ints, floats etc. But how would it differentiate from structs? so i wrote T operator = (const SomeGenericBase& v); The idea was the GenericBase would be unsed instead then i can do v.Whatever. But that backfires bc the functions i want wouldnt exist, unless i use virtual, but virtual templates dont exist. Also i would hate to use virtual I think the solution is to get rid of ints and have it convert to something that can do .as(). So i wrote something up but now i have the same problem, how does that differentiate ints and structs that have the .as() function template?

  • What's the state of PHP unit testing frameworks in 2010?

    - by Pekka
    As far as I can see, PHPUnit is the only serious product in the field at the moment. It is widely used, is integrated into Continuous Integration suites like phpUnderControl, and well regarded. The thing is, I don't really like working with PHPUnit. I find it hard to set up (PEAR is the only officially supported installation method, and I hate PEAR), sometimes complicated to work with and, correct me if I'm wrong, lacking executability from a web page context (i.e. no CLI, which would really be nice when developing a web app.) The only competition to I can see is Simpletest, which looks very nice but hasn't seen a new release for almost two years, which tends to rule it out for me - Unit Testing is quite a static field, true, but as I will be deploying those tests alongside web applications, I would like to see active development on the project, at least for security updates and such. There is a SO question that pretty much confirms what I'm saying: Simple test vs PHPunit Seeing that that is almost two years old as well, though, I think it's time to ask again: Does anybody know any other serious feature-complete unit testing frameworks? Am I wrong in my criticism of PHPUnit? Is there still development going on for SimpleTest?

  • What should a teen dev do for practical experience in development?

    - by aviraldg
    What should a teen dev do for practical experience? If you want more details , then read on: I learnt programming when I was 9 , with GWBASIC (which I now hate) , which was what was taught @ school. That was done in a month. After that I learnt C++ and relearnt it (as I didn't know of templates and the STL before that) Recently I learnt PHP , SQL and Python. This was around the time I switched over to Ubuntu. I'd always loved the "GNUish" style of software development so I jumped right in. However , most of the projects that I found required extensive knowledge of their existing codebase. So , right now I'm this guy who knows a couple of languages and has written a couple of small programs ... but hasn't gone "big", if you get it. I would love suggestions of projects that are informal and small to medium sized , and do not require much knowledge of the codebase. Also note that I've looked at things like Google Summer of Code and sites like savannah.gnu.org and the first doesn't apply , since I'm still in school and the latter either has infeasable projects , or things that are too hard.

  • addField type image and thumbnail path

    - by Christiaan
    Hello, I have a Magento webshop and just created a custom module with the extension (Modulecreator). This module comes with a standard admin interface that can handle file uploads. I found out that if you want to show thumbnails you can use the 'image' field type (addField('myfield', 'image')) instead of the 'file' type field. But now i've got a problem. When I upload files, I save them in a subdirectory called 'slides' in the 'media' directory. But when I edit the item, the image path for the thumbnail next to the uploadfield is set to the 'media' folder. Not my folder as I set it to 'media/slides/'. I use the following code: $fieldset->addField('filename', 'image', array( 'label' => Mage::helper('slideshow')->__('File'), 'required' => true, 'name' => 'filename', )); I tried to set a 'path' key in the array, but this doesn't get picked up by Magento. Hate the lack of support for good and easy to use documentation by Magento... Maybe you can help me out to find a solution?

  • Random syntactical error in my php code that I can't find

  • crash when using stl vector at instead of operator[]

    - by Jamie Cook
    I have a method as follows (from a class than implements TBB task interface - not currently multithreading though) My problem is that two ways of accessing a vector are causing quite different behaviour - one works and the other causes the entire program to bomb out quite spectacularly (this is a plugin and normally a crash will be caught by the host - but this one takes out the host program as well! As I said quite spectacular) void PtBranchAndBoundIterationOriginRunner::runOrigin(int origin, int time) const // NOTE: const method { BOOST_FOREACH(int accessMode, m_props->GetAccessModes()) { // get a const reference to appropriate vector from member variable // map<int, vector<double>> m_rowTotalsByAccessMode; const vector<double>& rowTotalsForAccessMode = m_rowTotalsByAccessMode.find(accessMode)->second; if (origin != 129) continue; // Additional debug constrain: I know that the vector only has one non-zero element at index 129 m_job->Write("size: " + ToString(rowTotalsForAccessMode.size())); try { // check for early return... i.e. nothing to do for this origin if (!rowTotalsForAccessMode[origin]) continue; // <- this works if (!rowTotalsForAccessMode.at(origin)) continue; // <- this crashes } catch (...) { m_job->Write("Caught an exception"); // but its not an exception } // do some other stuff } } I hate not putting in well defined questions but at the moment my best phrasing is : "WTF?" I'm compiling this with Intel C++ 11.0.074 [IA-32] using Microsoft (R) Visual Studio Version 9.0.21022.8 and my implementation of vector has const_reference operator[](size_type _Pos) const { // subscript nonmutable sequence #if _HAS_ITERATOR_DEBUGGING if (size() <= _Pos) { _DEBUG_ERROR("vector subscript out of range"); _SCL_SECURE_OUT_OF_RANGE; } #endif /* _HAS_ITERATOR_DEBUGGING */ _SCL_SECURE_VALIDATE_RANGE(_Pos < size()); return (*(_Myfirst + _Pos)); } (Iterator debugging is off - I'm pretty sure) and const_reference at(size_type _Pos) const { // subscript nonmutable sequence with checking if (size() <= _Pos) _Xran(); return (*(begin() + _Pos)); } So the only difference I can see is that at calls begin instead of simply using _Myfirst - but how could that possibly be causing such a huge difference in behaviour?

  • How do software projects go over budget and under-deliver?

    - by Carlos
    I've come across this story quite a few times here in the UK: NHS Computer System Summary: We're spunking £12 Billion on some health software with barely anything working. I was sitting the office discussing this with my colleagues, and we had a little think about. From what I can see, all the NHS needs is a database + middle tier of drugs/hospitals/patients/prescriptions objects, and various GUIs for doctors and nurses to look at. You'd also need to think about security and scalability. And you'd need to sit around a hospital/pharmacy/GPs office for a bit to figure out what they need. But, all told, I'd say I could knock together something with that kind of structure in a couple of days, and maybe throw in a month or two to make it work in scale. If I had a few million quid, I could probably hire some really excellent designers to make a maintainable codebase, and also buy appropriate hardware to run the system on. I hate to trivialize something that seems to have caused to much trouble, but to me it looks like just a big distributed CRUD + UI system. So how on earth did this project bloat to £12B without producing much useful software? As I don't think the software sounds so complicated, I can only imagine that something about how it was organised caused this mess. Is it outsourcing that's the problem? Is it not getting the software designers to understand the medical business that caused it? What are your experiences with projects gone over budget, under delivered? What are best practices for large projects? Have you ever worked on such a project?

  • What's a good way to write batch scripts in C#?

    - by Scott Bilas
    I would like to write simple scripts in C#. Stuff I would normally use .bat or 4NT .btm files for. Copying files, parsing text, asking user input, and so on. Fairly simple but doing this stuff right in a batch file is really hard (no exceptions for example). I'm familiar with command line "scripting" wrappers like AxScript so that gets me part of the way there. What I'm missing is the easy file-manipulation framework. I want to be able to do cd(".."), copy(srcFile, destFile) type functionality. Tools I have tried: NANT, which we use in our build process. Not a good scripting tool. Insanely verbose XML syntax and to add a simple function you must write an extension assembly. Can't do it inline. PowerShell. Looks great, but I just haven't been able to switch over to this as my primary shell. Too many differences from 4NT. Whatever I do needs to run from an ordinary command prompt and not require a special shell to run it through. Can PowerShell be used as a script executor? Perl/Python/Ruby. Really hate learning an entirely new language and framework just to do batch file operations. Haven't been able to dedicate the time I need to do this. Plus, we're a 99% .NET shop for our toolchain and I really want to leverage our existing experience and codebase. Are there frameworks out there that are trying to solve this problem of "make a batch file in C#" that you have used? I want the power of C#/.NET with the immediate-mode type functionality of a typical cmd.exe shell language. Am I alone in wanting something like this?

  • Better code for accessing fields in a matlab structure array?

    - by John
    I have a matlab structure array Modles1 of size (1x180) that has fields a, b, c, ..., z. I want to understand how many distinct values there are in each of the fields. i.e. max(grp2idx([foo(:).a])) The above works if the field a is a double. {foo(:).a} needs to be used in the case where the field a is a string/char. Here's my current code for doing this. I hate having to use the eval, and what is essentially a switch statement. Is there a better way? names = fieldnames(Models1); for ix = 1 : numel(names) className = eval(['class(Models1(1).',names{ix},')']); if strcmp('double', className) || strcmp('logical',className) eval([' values = [Models1(:).',names{ix},'];']); elseif strcmp('char', className) eval([' values = {Models1(:).',names{ix},'};']); else disp(['Unrecognized class: ', className]); end % this line requires the statistics toolbox. [g, gn, gl] = grp2idx(values); fprintf('%30s : %4d\n',names{ix},max(g)); end

  • Why does this code leak? (simple codesnippet)

  • How to style "form" field labels in Windows Phone 7?

    - by Jeremy Bell
    Is there any standards guidance on how to style field labels next to form fields in windows phone 7 silverlight applications? For example, let's say I have a StackPanel with the TextBlock label and a TextBox for data entry. Currently I am using the default TextBlock Margin included in the PhoneTextSubtleStyle ("12,0,12,0"), and using a Margin of "0,-12,0,0" to push the TextBox up closer to the label: <StackPanel HorizontalAlignment="Left"> <TextBlock VerticalAlignment="Center" Text="Name" Style="{StaticResource PhoneTextSubtleStyle}" /> <TextBox Text="{Binding ItemName, Mode=TwoWay}" TextChanged="TextBox_TextChanged" VerticalAlignment="Center" Width="433" Margin="0,-12,0,0" /> </StackPanel> Note that the TextBox seems to have some internal padding of 12 pixels to the left and right, so that the TextBlock label and the TextBox control visually line up perfectly on the left. The problem is, I see existing apps with widely varying conventions for field label styling. Some do not do the negative margin adjustment, like I have above. Some don't. Some appear to override the label TextBlock Margin so that it is indented an additional 12 pixels on the left (i.e. "24,0,12,0" instead of the default "12,0,12,0"). Some apps put the labels to the left of the fields themselves (I hate that). Is there some standard design guidance on field labels in Windows Phone 7? I read through the design template PDF and could only determine that the field labels should be upper case on the first word (preferably only one word labels), and should NOT have a colon at the end. I didn't see anything with regards to margins or alignment between the label and the field.

  • Is Prolog the best language to solve this kind of problem?

    - by Milan Babuškov
    I have this problem containing some inequations and requirement to minimize a value. After doing some research on the Internet, I came to conclusion that using Prolog might be the easiest way to solve it. However, I never used Prolog before, and I would hate to waste my time learning it just to discover that it is not the right tool for this job. Please, if you know Prolog, take a look at this problem and tell me if Prolog is the right one. Or, if you know of some other language that is really suited for this. a + b + c >= 100 d + e + f >= 50 g + h >= 30 if (8b + 2e + 7h > 620) then y = 0.8 else y = 1.0 if (d > 35) then x = 0.9 else x = 1.0 5xa + 8yb + 5c + 3xd + 2ye + 2f + 6xg + 7yh = w. I need to find the values for a, b, c, d, e, f, g and h that minimize w. I'm not really asking for code, although I'd be grateful for some hint how to tackle this if Prolog is really good for it. Thanks.

  • How do I form a Rails link_to with custom field value as parameter

    - by rwheadon
    I have an invoice form where I'm giving the user opportunity to apply coupons to the invoice total. These coupons are held in another Model and I am going to do a lookup on the Coupon code (something like "20OFFONFRIDAY") which I will use to find what the restrictions and benefits of the coupon. (and to see if it even exists at all) The invoice does not have "coupon_code" on it so I hand forged the field onto my form with html: <% if (@invoice.status == 'new') %> <input id="coupon_code" name="coupon_code" type="text"/> <% end %> and I am calling a controller method with link_to and would like something like the following jquery enhanced link_to to work: <%= link_to "Apply Coupon", { :controller=>"invoices", :id=>@invoice.id, :coupon_code=>$('.coupon_code').val(), :action=>"apply_coupon_code" }, :method=>"post" %> ^formatted for easier reading Then inside my "apply_coupon_code" method I will go off to a couple other models and perform business logic before returning the updated invoice page. ...but maybe it's a pipe dream. I guess if push came to shove I could add the "coupon_code" field to my invoice model (even though it's persisted elsewhere.) so it's part of the entity and thus easily available on my form to send back into a controller, but I just hate adding a column to make a coupon validation easier. I figured I'd ping stackoverflow before taking that path.

  • How can I add file locations to a database after they are uploaded using a Perl CGI script?

    - by Paul K
    I have a CGI program I have written using Perl. One of its functions is to upload pics to the server. All of it is working well, including adding all kinds of info to a MySQL db. My question is: How can I get the uploaded pic files location and names added to the db? I would rather that instead of changing the script to actually upload the pics to the db. I have heard horror stories of uploading binary files to databases. Since I am new to all of this, I am at a loss. Have tried doing some research and web searches for 3 weeks now with no luck. Any suggestions or answers would be greatly appreciated. I would really hate to have to manually add all the locations/names to the db. I am using: a Perl CGI script, MySQL db, Linux server and the files are being uploaded to the server. I AM NOT looking to add the actual files to the db. Just their location(s).

  • How to make link become inactive?

    - by Konstantin Vasilcov
    The idea was simple: change li background color on hover to one color ul#menu li a:hover {...} change it on mouse press to the other color ul#menu li a:active {...} return the color to the original (normal) if the link is neither hover nor pressed The problem appeared to be that, if user rejected his intention and lets the mouse up away from the link, the back color stays as if it was pressed. Then I tried to research and came up with this: ul#menu li a:hover:active {...} It became better, and the link is not marked with special back color in a normal state after user presses the link and rejects. But the "on-hover" back color became equal to the active one. So it looks like the link gets "active" state and stays in it even after user releases mouse button. Hate to write this, but I am very new to html and css. So I may be missing something very basic here. Could you, please, suggest any way, how to achieve my goal? EDIT I've read this source CSS Styling links (thought there could be some other state to use instead of active), but found nothing suitable there...

  • Tools for Automated Source Code Editing

    - by Steve
    I'm working on a research project to automatically modify code to include advanced mathematical concepts (like adding random effects into a loop or encapsulating an existing function with a new function that adds in a more advanced physical model). My question to the community is: are there are any good tools for manipulating source code directly? I want to do things like Swap out functions Add variable declarations wherever they are required Determine if a function is multiplied by anything Determine what functions are called on a line of code See what parameters are passed to a function and replace them with alternatives Introduce new function calls on certain lines of code Wherever possible just leaving the rest of the code untouched and write out the results I never want to actually compile the code I only want to understand what symbols are used, replace and add in a syntactically correct way, and be able to declare variables at the right position. I've been using a minimal flex/bison approach with some success but I do not feel the it is robust. I hate to take on writing a full language parser just to add some new info to the end of a line or the top of a function. It seems like this is almost what is going to be required but it also seems like there should be some tools out there to do these types of manipulations already. The code to be changed is in a variety of languages, but I'm particularly interested in FORTRAN. Any thoughts?

  • Unable to run JAR file (created in Eclipse)

    - by Trist
    I hate starting a post with this but I'm new to Java... I've followed this tutorial to create a socket server (mines in Eclipse). I can run the server within Eclipse, all is well. But when I try to export the project I can't figure out how to run it. I keep getting this error (it varies depending on how I run it) Exception in thread "main" java.lang.NoClassDefFoundError: xsocketserver/Main Caused by: java.lang.ClassNotFoundException: xsocketserver.Main at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) I've read this problem relates to class paths being set. I've tried the following: java -cp libs/xSocket-2.8.12.jar xsocketserver.Main java -jar xSocketServer.jar java -classpath xSocketServer:xSocketServer/libs/xSocket-2.8.12.jar xsocketserver.Main plus many others. The file structure within the JAR is as follows: xSocketServer.jar -> xsocketserver -> Main.class -> xSocketDataHandler.class -> META-INF -> MANIFEST.MF -> libs -> xSocket-2.8.12.jar Incidentally I've tried adding my own manifest file which contains the Class-Path but when I check it it always reads: Manifest-Version: 1.0 Main-Class: xsocketserver.Main I'm guessing this is a common problem based on the number of hits I've seen in Google but I can't fathom what I'm doing wrong. Wrong Export settings maybe??

  • Unclear pricing of Windows Azure

    - by Dirk
    How do you people think about the Windows Azure pricing model and the way it is presented to the user? I just found out that Azure keeps charging hours for STOPPED instances. I just received a bill from more than 100 euro for 3 STOPPED instances (not) running "HelloAzure". I the past I also played around with Amazon Web Services. Amazon doesn't charge for stopped instances. I was wondering: "Should I have known this before, or is Microsoft doing a bad job in clear communication in the pricing model?" Quote from http://www.microsoft.com/windowsazure/pricing/ : Compute time, measured in service hours: Windows Azure compute hours are charged only for when your application is deployed. When developing and testing your application, developers will want to remove the compute instances that are not being used to minimize compute hour billing. Partial compute hours are billed as full hours. I read this, so I stopped all instances after a few hours playing around. Now it seems I should have deleted them, not just "stopped". Strictly speaking, all depends on the definition of the word "deployed". If you upload an application, but it is not running, can it still be regarded as being "deployed"? May be, but when you read this for the first time, with AWS experience in mind, I don't think it's 100% clear what this means. Technically speaking, an uploaded application only uses (read: should only use / needs only) a few MB harddrive space. It doesn't require any CPU time. If Azure wants to reserve CPU's for not running instances.. well, that's Azure's choice, not mine. I don't want to spread a hate campaign at all, but I do want to know how people think about this subject. Should Microsoft be more clear about their pricing model or do you think it's clear enough? Second question: did anyone got refunded for a similar case? Thanks in advance! UPDATE 27-01-2011 I sent an email to customer support a few days ago, but I guess that didn't reach anu human being because I didn't hear anything from it. So, I made a telephone call today with a Dutch customer support representative (I live in Holland). She totally understood the problem and she's trying to get a refund for me. However, she mentioned that "usually these refund requests are denied", but she's going to try. She also mentioned that I'm not the first one with this (or similar) problem. UPDATE 28-01-2011 I just received a phonecall from Microsoft support. The lady told me some good news: the money will refunded. However, the invoice has not been made yet, and my creditcard will first be chardged, after which it will be refunded, but hey, that's no problem for me! I'm glad the way it's solved! Thanks everybody!

  • Detach current session and attach to another session, done with one script, can I?

    - by Jimm Chen
    After reading the vague official doc of GNU screen( http://www.gnu.org/software/screen/manual/screen.html ) and asking quite some questions at this site. I still cannot figure out how to accomplish such a task with a shell script. This task costs some words to describe. Assume I'm using PuTTY to telnet into my Linux server. ?STEP 1? Launch 2 telnet connections . From putty window 1 (PTWIN1),telnet into Linux Bash shell, execute screen -RR to launch a screen session, and get session name 21385.pts-4.linux-ic37 . From putty window 2 (PTWIN2), do that same as in PTWIN1, but this time, I get session name 22041.pts-9.linux-ic37 . Now, we have two screen sessions running simultaneously. We can check this: $ screen -ls There are screens on: 22041.pts-9.linux-ic37 (Attached) 21385.pts-4.linux-ic37 (Attached) 2 Sockets in /var/run/uscreens/S-chj2. ?STEP 2? Assume that for some reason, PTWIN1's TCP connection is lost abnormally(but server doesn't know that), and an urgent work is pending on session 21385 and I want to quickly regain control of it. Fortunately, we know the 21385 session is still there, so, I want to have PTWIN2 attach to session 21385. Because I hate to remember the esoteric screen option all the time, so I decide to write a script called sttach. I hope that sttach 21385.pts-4.linux-ic37 can let me attach to session 21385(for PTWIN2). Now, let's say sttach works well and I take control of 21385 on PTWIN2. ?STEP 3? Some minutes later. I want to go back to work on session 22041. Here, please allow me to have PTWIN2 remain associated with session 21385. What I would like to do is to launch another putty window (PTWIN3), telnet into server, and execute sttach 22041.pts-9.linux-ic37 in hope that I can resume session 22041 on PTWIN3 . You can see the benefit of sttach: as long as I know the target session name, I can call it to have my PuTTY window switch to that session, regardless whether the target session is "(Attached)" or "(Detached)", and regardless whether the running context is inside a screen session or not. Now the question: How to write the (Bash) script sttach? I mean, run screen with appropriate options in sttach to accomplish the goal. Waiting for your kind answer. Thank you. My previous questions regarding GNU screen: GNU screen, how to get current sessionname programmatically Is it possible to change GNU screen session name after created? How do I know I'm running inside a linux "screen" or not? My env: openSUSE Linux 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

  • Forms authentication failed between web server and sql server

    - by Matt Bear
    I've actually found the solution, but I'm trying to understand why it failed, and why my solution fixed the problem. We have an application that uses forms authentication between a web server and sql server, web server runs server 2008, sql server runs 2008 r2, and sql server 2008. In august the sql server was patched with .net 3.5.1, the web server was untouched, and the forms authentication continued to work. 1 week ago we virtualized the web server onto our vSphere server because of failing hardware. Afterwards the form authentication failed with event code 4005, detail code 50201, The ticket supplied was invalid (on the sql server). In fact the sql server started generating Schannel errors and began blue screening 3-4 times a day. At this point I touched the sql server for the first time(ever), the errors were non specific, any reference to them I could find had to do with either zone alarm(which we don't run), or memory errors. So I applied service pack 1, which stopped the blue screening, but did not fix the forms authentication. At this point we had a work around, so we put it on the back burner while we completed another project, and I was able to get back on it last night. First thing was to adjust some code in the webconfig file on the sql server, nothing, next was regenerate and change out the machine key, still no change. Update the DNS servers, no change. Finally I went through and installed all windows updates, two reboots, (over RDP installed a network card driver which failed, and did not have my server room key, that was fun). After that, forms authentication was working again. And the sql server stopped generating as many errors, I've gotten two schannel errors since then. In short, forms authentication began failing when the web server was cloned onto a virtual machine, which caused the sql server to blue sceen? and forms authentication to fail. And could only be fixed by applying patches to the sql server?(I'm wishing I had patched the servers one at a time so I could know for sure which patch on which server fixed it). My question is why did it fail, and why did patching fix it? I hate fixing something without fully understanding the why and how.
