• In VB.net websites, VS2008 ALWAYS uses space indentation for new files

  - by Jez

  So, I've changed my settings in Tools | Options | Text Editor, for All Languages, Basic, and C#, to having Block indenting, and 'Keep tabs'. I've also tried this with Smart indenting too. Now, although once I start editing a file, its auto indentation is done with tabs, when I create a new web form in my ASP.net website, VS2008 insists on creating the initial code with space indentation. So for example, I'll get an aspx.vb file for my new page like so: Partial Class Admin_Index Inherits System.Web.UI.Page End Class Note that the 'Inherits' line is SPACE-indented, even though I have the text editor settings set to keep tabs. Is there any way I can make the default created files indented with tabs, not spaces? Or is VS just too stubborn? :-) By the way, please don't just respond and say this is petty as I can quickly change that one line of indentation to using a tab. I know this, but I have a software team that find it irritating as we have an SVN hook that prevents checkins if there's any space-indentation. It would be very useful if any newly-created files have tab indentation from the start, rather than us having to change it every time.

• MS Query Analyzer / Management Studio replacement?

  - by kprobst

  I've been using SQL Server since version 6.5 and I've always been a bit amazed at the fact that the tools seem to be targeted to DBAs rather than developers. I liked the simplicity and speed of the Query Analyzer for example, but hated the built-in editor, which was really no better than a syntax coloring-capable Notepad. Now that we have Management Studio the management part seems a bit better but from a developer standpoint the tools is even worse. Visual Studio's excellent text editor... without a way to customize keyboard bindings!? Don't get me started on how unusable is the tree-based management hierarchy. Why can't I re-root the tree on a list of stored procs for example the way the Enterprise Manager used to allow? Now I have a treeview that needs to be scrolled horizontally, which makes it eminently useless. The SQL server support in Visual Studio is fantastic for working with stored procedures and functions, but it's terrible as a general ad hoc data query tool. I've tried various tools over the years but invariably they seem to focus on the management side and shortchange the developer in me. I just want something with basic admin capabilities, good keyboard support and requisite DDL functionality (ideally something like the Query Analyzer). At this point I'm seriously thinking of using vim+sqlcmd and a console... I'm that desperate :) Those of you who work day in and day out with SQL Server and Visual Studio... do you find the tools to be adequate? Have you ever wished they were better and if you have found something better, could you share please? Thanks!

• Force compile-time linking of all classes in a SWC

  - by aaaidan

  Using Flash CS4, I am making a game that has a dozen or so sounds and a couple of music tracks. To cut down on publish/compile time, I have moved the sounds and music into an (external) SWC, which is located in a "Library Path" for the project. This works, but with a caveat... Until before I externalised the assets, I had been dynamically instantiating the Sound objects of the embedded sound by getting their classes with getDefinitionByName. // something like... var soundSubClass:Class = Class(getDefinitionByName(soundClassName)); var mySound:Sound = new soundSubClass(); But now that they're located in an external SWC, I need to have "concrete" references to the classes in order to load them like this, otherwise they are not included in the published SWF, and there is a runtime error when getDefinitionByName tries to get a class that doesn't exist. So, my question: in Flash Professional CS4, is there any way to force a library's assets to be included, regardless of whether they are statically linked? FlashDevelop has a compiler option "SWC Include Libraries", which is exactly what I want, and is distinct from the "SWC Libraries" option. The description of the "SWC Include Libraries" option is "Links all classes inside a SWC file to the resulting application SWF file, regardless of whether or not they are used." (Also, it's important to me that all the assets are contained within the one compiled SWF. Linking at runtime isn't what I'm after.)

• (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user

  - by ChelleATL

  I am trying to deploy a report to the Reporting Services Server but keep running up against this error: An error occurred during client rendering. An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'dataSource1'. (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user 'DOMAIN\useradmin', error code 0x5. Here’s my situation: Everything is being ran using DOMAIN\useradmin and the report is using a remote database. Reporting Services and SQL Server are both ran under DOMAIN\useradmin. DOMAIN\useradmin is a windows AD login and is part of the server machine Administrators group. My test report is using a data source model that in turn is using a data source that is connection to a database on a different SQL Server. The data source is using “Credentials stored securely in the report server” with the options “Use as Windows credentials when connecting to the data source” and “Impersonate the authenticated user after a connection has been made to the data source.” I am using the credentials of DOMAIN\useradmin that is the db owner of the remote database. DOMAIN\useradmin is assigned the roles, System Administrator, System User and Browser, Content Manager, My Reports, Publisher, Report Builder. So if everything is being run under an über AD account, why I am getting this Could not obtain information about Windows NT group/user 'DOMAIN\useradmin' error? Under normal circumstances , an AD login with Publisher permissions will developing reports using a datasource model created by DOMAIN\useradmin but using one of the remote database’s users which is mapped from yet another AD login. I ran the following statements and non errors were returned: use master go xp_grantlogin 'DOMAIN\useradmin' go xp_logininfo 'DOMAIN\useradmin' go

• How test that ASP.NET MVC route redirects to other site?

  - by Matt Lacey

  Due to a prinitng error in some promotional material I have a site that is receiving a lot of requests which should be for one site arriving at another. i.e. The valid sites are http://site1.com/abc & http://site2.com/def but people are being told to go to http://site1.com/def. I have control over site1 but not site2. site1 contains logic for checking that the first part of the route is valid in an actionfilter, like this: public override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); if ((!filterContext.ActionParameters.ContainsKey("id")) || (!manager.WhiteLabelExists(filterContext.ActionParameters["id"].ToString()))) { if (filterContext.ActionParameters["id"].ToString().ToLowerInvariant().Equals("def")) { filterContext.HttpContext.Response.Redirect("http://site2.com/def", true); } filterContext.Result = new ViewResult { ViewName = "NoWhiteLabel" }; filterContext.HttpContext.Response.Clear(); } } I'm not sure how to test the redirection to the other site though. I already have tests for redirecting to "NoWhiteLabel" using the MvcContrib Test Helpers, but these aren't able to handle (as far as I can see) this situation. How do I test the redirection to antoher site?

• Node.js/ v8: How to make my own snapshot to accelerate startup

  - by Anand

  I have a node.js (v0.6.12) application that starts by evaluating a Javascript file, startup.js. It takes a long time to evaluate startup.js, and I'd like to 'bake it in' to a custom build of Node if possible. The v8 source directory distributed with Node, node/deps/v8/src, contains a SconScript that can almost be used to do this. On line 302, we have LIBRARY_FILES = ''' runtime.js v8natives.js array.js string.js uri.js math.js messages.js apinatives.js date.js regexp.js json.js liveedit-debugger.js mirror-debugger.js debug-debugger.js '''.split() Those javascript files are present in the same directory. Something in the build process apparently evaluates them, takes a snapshot of state, and saves it as a byte string in node/out/Release/obj/release/snapshot.cc (on Mac OS). Some customization of the startup snapshot is possible by altering the SconScript. For example, I can change the definition of the builtin Date.toString by altering date.js. I can even add new global variables by adding startup.js to the list of library files, with contents global.test = 1. However, I can't put just any javascript code in startup.js. If it contains Date.toString = 1;, an error results even though the code is valid at the node repl: Build failed: -> task failed (err #2): {task: libv8.a SConstruct -> libv8.a} make: *** [program] Error 1 And it obviously can't make use of code that depends on libraries Node adds to v8. global.underscore = require('underscore'); causes the same error. I'd ideally like a tool, customSnapshot, where customSnapshot startup.js evaluates startup.js with node and then dumps a snapshot to a file, snapshot.cc, which I can put into the node source directory. I can then build node and tell it not to rebuild the snapshot.

• Problem with RVM and gem that has an executable

  - by djhworld

  Hi there, I've recently made the plunge to use RVM on Ubuntu. Everything seems to have gone swimmingly...except for one thing. I'm in the process of developing a gem of mine that has a script placed within its own bin/ directory, all of the gemspec and things were generated by Jeweler. The bin/mygem file contains the following code: - #!/usr/bin/env ruby begin require 'mygem' rescue LoadError require 'rubygems' require 'mygem' end app = MyGem::Application.new app.run That was working fine on the system version of Ruby. Now...recently I've moved to RVM to manage my ruby versions a bit better, except now my gem doesn't appear to be working. Firstly I do this: - rvm 1.9.2 Then I do this: - rvm 1.9.2 gem install mygem Which installs fine, except...when I try to run the command for mygem mygem I just get the following exception: - daniel@daniel-VirtualBox:~$ mygem <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mygem (LoadError) from <internal:lib/rubygems/custom_require>:29:in `require' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/gems/mygem-0.1.4/bin/mygem:2:in `<top (required)>' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `load' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `<main>'mygem NOTE: I have a similar RVM setup on MAC OSX and my gem works fine there so I think this might be something to do with Ubuntu?

• Trouble using latex in Matplotlib / Scipy etc.

  - by ajhall

  I'm having some issues with my first attempts at using matplotlib and scipy to make some scatter plots of my data (too many variables, trying to see many things at once). Here's some code of mine that is working fairly well... import numpy from scipy import * import pylab from matplotlib import * import h5py FileID = h5py.File('3DiPVDplot1.mat','r') # (to view the contents of: list(FileID) ) group = FileID['/'] CurrentsArray = group['Currents'].value IvIIIarray = group['IvIII'].value PFarray = group['PF'].value growthTarray = group['growthT'].value fig = pylab.figure() ax = fig.add_subplot(111) cax = ax.scatter(IvIIIarray, growthTarray, PFarray, CurrentsArray, alpha=0.75) cbar = fig.colorbar(cax) ax.set_xlabel('Cu / III') ax.set_ylabel('Growth T') ax.grid(True) pylab.show() I tried to change the code to include latex fonts and interpreting, none of it seems to work for me, however. Here's an example attempt that didn't work: import numpy from scipy import * import pylab from matplotlib import * import h5py rc('text', usetex=True) rc('font', family='serif') FileID = h5py.File('3DiPVDplot1.mat','r') # (to view the contents of: list(FileID) ) group = FileID['/'] CurrentsArray = group['Currents'].value IvIIIarray = group['IvIII'].value PFarray = group['PF'].value growthTarray = group['growthT'].value fig = pylab.figure() ax = fig.add_subplot(111) cax = ax.scatter(IvIIIarray, growthTarray, PFarray, CurrentsArray, alpha=0.75) cbar = fig.colorbar(cax) ax.set_xlabel(r'Cu / III') ax.set_ylabel(r'Growth T') ax.grid(True) pylab.show() I'm using fink installed python26 with corresponding packages for scipy matplotlib etc. I've been using iPython and manual work instead of scripts in python. Since I'm completely new to python and scipy, I'm sure I'm making some stupid simple mistakes. Please enlighten me! I greatly appreciate the help!

• Disable proxy for entire application?

  - by Brent

  Ever since upgrading to Visual Studio 2010, I'm running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds before completing. Subsequent calls work quickly. I've narrowed down the problem to a proxy issue. If I manually disable proxy settings, I don't experience this delay: Dim wrq As WebRequest = WebRequest.Create(Url) wrq.Proxy = Nothing What's strange is that there are no proxy settings enabled on this machine in Internet Options. What I'm wondering is if there is a way to disable proxy settings for my entire project in one shot without explicitly disabling as above for every web object. The main reason I want to be able to do this is that I'm trying to use an API (http://code.google.com/p/google-api-for-dotnet/) which uses web requests, but does not provide any way to manually disable proxy settings. I have found some information suggesting that I need to add some proxy information to the app.config file, but I get errors building my program if I make an edits to that file. Can anyone point me in the right direction?

• JSF Managed Property question

  - by kidvid

  I have a search page that I'll called "Parent." The search page references a country lookup page that I'll call "Child." When the user selects a country on Child's page and clicks on OK, I set the country back into the parent page. I do this by calling a method on the Parent page called "UpdateCountryCodeWithLookupValue(Child child)" When the user clicks on OK on the Child page, that method gets called in the parent, wherein it'll get the selected country code out of the Child page and set it into a text entry field. My question has to do with the proper way to set up this relationship in the faces config file. The way I have it now is that the child has a managed property for the parent. I.e., in my Child page I defined a method called "SetParent(Parent parent)". Is there any drawback to doing it this way? Would it be preferable to set the managed property so that the Child page class is a property of the parent instead of vice-versa? Let's say that I could have two Parent (search) pages open at the same time, and each of these was able to open the Child page (country code lookup). What would be the ramification for that circumstance in terms of the managed property in the faces config file? Thanks, Adrian

• PHP site keeps opening to blank page, no errors.

  - by gene

  First, the premises: PHP loaded on IIS6 on Win2003 STD R2 SP2, PHP_5213 using FastCGI, MySQL_5145. Customer sent me the site files, which I unzipped to C:\InetPub\wwwroot\<site root>, then I created a new site in IIS, pointed to <site root>, added test.php to the site files for testing and it works, but visiting index.php produces a blank page with no errors. The readme.txt file present makes reference to application.php and explains root folder var and sets it to a non-existent file. I don't know PHP syntax, but I tried several logical changes with zero results. At this point I'm not even sure if that is the problem anymore. With PHP, MySQL & site debugging have put in over 20 hours. Still confused, I have resorted to heavy drug use and purchased a small firearm, loaded with a single round (even this seemed to take an inordinate amount of time). I've given up all hope. Someone please help save a new server and/or old administrator.

• ildasm and dynamic exe files

  - by TonyNeallon

  Hi There, I am trying to create an application can modify properties in IL to create a slightly different executable. E.g Client A runs app and a label on the WinForm label Reads "Client A:". Client B runs the app and Label Says "Client B". Easy I know using config files or resource files but thats not an option for this project. The Main program needs to be able to generate .exe file dynamically based on some form fields entered by user. My solution was to create a standalone executable that contained all the elements which I needed to make dynamic. I then used ildasm to generate the IL and thought that I could use this IL and substitute tags for the elements i wanted to make dynamic. I could then replace those tags at runtime after user filled the form using regex etc. The problem is, the if i re save the IL file generated by ILDASM as an exe and try to run it. I just launches console and does nothing. Am I going about this the wrong way? I didnt want to delve into Reflection as the dynamic .exe is a really simple one and I thought reverse engineering IL with ildasm would be the quickest way. You thoughts and pointers are much appreciated. Tony

• Why would some $_POST variables go missing for a form with PHP?

  - by Chad Johnson

  Sometimes, multiple times a day in fact, users of my web application are submitting a certain form which has about a dozen form fields, half of which are hidden fields, and half of the $_POST data is simply not present in the processing script. Note that the fields that are not present are at the very bottom of the form. I know this because this raises a fatal error, and an email is dispatched to me which includes the post data. And of course, neither I nor any of the developers on my team can reproduce the problem. Flash is involved in the process, as I'm using a library called Uploadify to display a progress meter. Here is the flow...does anyone have ANY ideas at all why some of the post data would be getting wiped out? User visits edit screen for a page in the CMS I am using. Record id for the page is put into a form as a hidden value. User clicks the Uploadify browse button and selects a file (only single file selection is allowed). User clicks Submit button for my form. jQuery intercepts the form submit action, triggers Uploadify to start uploading, and returns false for the submit action (manually cancelling the form submit event so that Uploadify can take over). Uploadify uploads to a custom process script. Uploadify finishes uploading and triggers the Javascript completion callback. The Javascript callback calls $('#myForm').submit() to submit the form. This happens on multiple browsers (Firefox 3.5, 3.6, Safari, Internet Explorer 7, 8) and multiple platforms (Mac OS 10.5, 10.6 and Windows XP, 7).

• How do I add programmatically-generated new files to source control?

  - by Alex Basson

  This is something I've never really understood about source control, specifically Subversion (the only source control I've ever used, which isn't saying much). I'm considering moving to git or Mercurial, so if that affects the answer to my question, please indicate as such. Ok. As I understand it, every time I create a new file, I have to tell SVN about it, so that it knows to add it to the repository and place it under control. Something like: svn add newfile That's fine if I'm the one creating the file: I know I created it, I know its name, I know where it lives, so it's easy to tell SVN about it. But now suppose I'm using a framework of some kind, like Rails, Django, Symfony, etc., and suppose I've already done the initial commit. All of these frameworks create new files programmatically, often many at once, in different directories, etc. etc. How do I tell the source control about these new files? Do I have to hunt each one of them down individually and add them? Is there an easier way? (Or am I possibly misunderstanding something fundamental about source control?)

• Shutdown and WakeUp Script C#

  - by Stephen Murby

  Hiya I am very new to C#, infact this is basically my first task set by work whilst i learn the language. Yes i am also new to programming, be gentle :). Context: My script needs to query active directory, grab of OU's and put them to a combo box in a form. Next query ActDir for a list of machines in a selected OU (Done this in a vbscript already) Next query the machines in turn for there IP, and MAC addresses.(Done this in a vbscript already) Next needs to shut those machines down(Done this in a vbscript already) and dump all the machine and NIC info to a txt file The other half of the script grabs the info for the machines out of the text file and sends them a magic packet to wake them up. The shutdown section i have already written a VBscript for, but decided it wasn't future prrof, and i was learninc C# at home, so figured it was the best option to start over with. Im not looking for anyone to write this for me, but if anyone had any pointers on where to go for information etc. . . It would be more than appreciated :)

• How to install OpenCV 2.0 on win32

  - by Jive Dadson

  I need to install OpenCV on Win32. I do not have it installed currently. I downloaded OpenCV-2.0.0a-win32.exe and ran it. What the heck do I do now? There are no .lib's and whatnot. I found some instructions for building the release using cmake at http://opencv.willowgarage.com/wiki/InstallGuide . I downloaded the latest and greatest cmake, and tried to follow the instructions, but I was guessing. No joy. I specified VC++9 when I did the "configure," but cmake built a VC++ 6 dsw file. No vcproj. I converted the dsw into a vc++9 vcproj anyway, just to see if it would work. Nope. It compiled lots of files, but many failed because it could not find omp.h. Sure enough, it's not there, anywhere. The build log said, 'A tool returned an error code from "Performing Custom Build Step".' I am lost. Ideally, I would like to find a full installation with all the files pre-built for Win32 vc++ 2008. Failing that, I need instructions that even I can follow. Short sentences and small words, but lots of them. Please help! UPDATE: I tried to build just CXCORE. It complained, "cannot open file 'VCOMPD.lib'" There's that OMP again.

  I want to make something happen when back button is pressed so I put this code in Myhtml.js file : function wlCommonInit(){ /* * Application is started in offline mode as defined by a connectOnStartup property in initOptions.js file. * In order to begin communicating with Worklight Server you need to either: * * 1. Change connectOnStartup property in initOptions.js to true. * This will make Worklight framework automatically attempt to connect to Worklight Server as a part of application start-up. * Keep in mind - this may increase application start-up time. * * 2. Use WL.Client.connect() API once connectivity to a Worklight Server is required. * This API needs to be called only once, before any other WL.Client methods that communicate with the Worklight Server. * Don't forget to specify and implement onSuccess and onFailure callback functions for WL.Client.connect(), e.g: * * WL.Client.connect({ * onSuccess: onConnectSuccess, * onFailure: onConnectFailure * }); * */ // Common initialization code goes here } WL.App.overrideBackButton(backFunc); function backFunc(){ alert('You will back to previous page'); } but after build and deploy the app and I running it, nothing happened after I pressed back button, anybody have the solution ?

• Unregistering COM dll with a C# Setup Project

  - by lb

  Hi All. I've been stuck on this one for a while. I'll try explain in the simplest terms and at the best of my knowledge. I will honour any help. I've got a C# project which uses a VB6 compiled ActiveX DLL that I'm constantly updating. I compile the setup project, send it to the client and they run the setup. When building the updated setup project, I would increase the 'Version' of the setup project so it wouldn't bother with 'Another version is already installed'. What started happening after a few updates I began to notice the DLL would not be updated to the new version in the installer. The client computer had the original DLL both installed and registered. First symptom: method not found exceptions from the client C# code. This is not a shared DLL and only this application needs it. I've noticed that when uninstalling the application (through the usual procedure) the DLL is also not removed from the application folder although I would set this file's property 'Permanent' to false. The registration entries in the registry are mantained also. I do update in VS6.0 the version of the DLL (usually increase the build number) before building it. Then in VS2008, I remove it from the References, and add it again from the 'Browse tab', without re-registering it on my dev machine and adding it from the COM tab. I've thought of these options. Custom step in Setup project to regsvr32.exe /u 'hardcoded path of my dll' at uninstall (ugly) Somehow find out how the 'Isolate' property can work for me without registering Find out how to execute setup project 'Conditions' that would actually check the version of the library and to update the file accordingly at every install) Any help would be incredibly welcome.

• x86_64 printf segfault after brk call

  - by gmb11

  While i was trying do use brk (int 0x80 with 45 in %rax) to implement a simple memory manager program in assembly and print the blocks in order, i kept getting segfault. After a while i could only reproduce the error, but have no idea why is this happening: .section .data helloworld: .ascii "hello world" .section .text .globl _start _start: push %rbp mov %rsp, %rbp movq $45, %rax movq $0, %rbx #brk(0) should just return the current break of the programm int $0x80 #incq %rax #segfault #addq $1, %rax #segfault movq $0, %rax #works fine? #addq $1, %rax #segfault again? movq $helloworld, %rdi call printf movq $1, %rax #exit int $0x80 In the example here, if the commented lines are uncommented, i have a segfault, but some commands (like de movq $0, %rax) work just fine. In my other program, the first couple printf work, but the third crashes... Looking for other questions, i heard that printf sometimes allocates some memory, and that the brk shouldn't be used, because in this case it corrupts the heap or something... I'm very confused, does anyone know something about that? EDIT: I've just found out that for printf to work you need %rax=0.

• JAAS and WebLogic 10.3: Granting specific codebase permissions to a JAR bundled within an EAR

  - by Jason

  Here's my scenario: I have a JAR within the APP-INF/lib of my EAR, to be deployed within WebLogic 10g Release 3 against which I wish to grant specific permissions. e.g., grant codebase "file:/c:/somedir/my.jar" { permission java.net.SocketPermission "*:-","accept,connect,listen, resolve"; permission java.net.SocketPermission "localhost:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "127.0.0.1:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "230.0.0.1:-","accept,connect,listen,resolve"; permission java.util.PropertyPermission "*", "read,write"; permission java.lang.RuntimePermission "*"; permission java.io.FilePermission "<<ALL FILES>>","read,write,delete"; permission javax.security.auth.AuthPermission "*"; permission java.security.SecurityPermission "*"; }; Questions: Where is the best place to define this grant - in the java.policy of the JRE, WL server's weblogic.policy, or within a XML packaged within the EAR How do I define the codebase URL to the JAR? The examples I have seen have an explicit reference to the JAR on the file system, however I am deploying the JAR packaged up within an EAR. Thanks!
