  • .NET "must-have" development tools

    - by nzpcmad
    James Avery wrote a classic article a while back entitled Ten Must-Have Tools Every Developer Should Download Now which is a companion to Visual Studio Add-Ins Every Developer Should Download Now and Scott Hanselman has an excellent list on his blog but if you were on a desert island and were only allowed three .NET development tools which ones would you pick? Update: Assuming you already have an IDE like Visual Studio ... Update (5) : Up to 08/01 : The current state of play: Reflector 13 Resharper 9 NUnit + TestDriven.Net 7 Refactor Pro 4 Process Explorer (other Sysinternals) 3 SnippetCompiler 3 CodeRush 3 MSDN Library 2 LinqPad 2 Cruisecontrol.net 2 VMWare 2 RhinoMocks 2 Fiddler 2 PowerShell 2 PowerCommands for VS 2008 1 Sandcastle 1 SQL Profiler 1 Redgate ANTS profiler 11 NCover 1 VisualSVN 1 Rubber Ducky 1 WinMerge 1 NAnt 1 ViEmu 1 AnkhSVN 1 dotTrace Profiler 1 BeyondCompare 1 DPack VS Plugin 1 WCF Trace Viewer (SDK) 1 xUnit.net 1 SourceGear DiffMerge 1 Ghostdoc 1 Expression Studio 1 XAML Pad 1 KaXaml 1 Blender for 3D modeling 1 Snoop a WPF tool 1 DiffMerge 1 DPack 1 NDepend 1 Kodos 1 WatiN 1 HTTPWatch Basic Edition 1 Paint.Net 1 Mole For VS 1 What I find particularly interesting about this is that "NUnit + TestDriven.Net " is right up there in third place which shows the growing emphasis on testing as an integral part of the development process rather than as an adjunct which is simply bolted on. And I'm somewhat perplexed that Codesmith didn't receive a single vote?

  • TeamCity GitHub Private Key Access Denied

    - by Chance Robertson
    Does anyone know of a tutorial for using TeamCity with github with ssh private keys. I have tried to set up git hub to connect and I either get a authentication error or get access denied. I am running TeamCity on Windows 2003. I am running the build agent as a custom account. I am running the web server under the administrator account. I have create a key for the custom account and administrator account. I now get an error that: The connection test failed: com.jcraft.jsch.JSchException: java.io.FileNotFoundException: C:\Documents and Settings\Administrator.ssh (Access is denied) If anyone has successfully set this up please help. I am going on 3 hours into this and want to get it solved. Thanks.

  • $facebook->getSession() returns null in the example code. is that ok?

    - by Toto
    Running the example code for the Facebook API I get a null session object, and I should get a non-null object giving the comment in the code. What am I doing wrong? In other words, in my index.php this fragment from the example code shows "no session" when I go to http://apps.facebook.com/my_app in my browser: <?php require './facebook.php'; // Create our Application instance. $facebook = new Facebook(array( 'appId' => '...', // actual value replaced by '...' for this post 'secret' => '...', // actual value replaced by '...' for the post 'cookie' => true, )); // We may or may not have this data based on a $_GET or $_COOKIE based session. // // If we get a session here, it means we found a correctly signed session using // the Application Secret only Facebook and the Application know. We dont know // if it is still valid until we make an API call using the session. A session // can become invalid if it has already expired (should not be getting the // session back in this case) or if the user logged out of Facebook. $session = $facebook->getSession(); if ($session) { echo "session ok"; } else { echo "no session"; } ?> Note: in my server index.php and facebook.php are in the same folder.

  • SSRS Export to Excel not working through VPN (Juniper SA4000)

    - by Veynom
    We have a SharePoint (MOSS 2007 on Win2003 R2) with SSRS reports (from SQL 2005) embedded in it. When we connect to the SharePoint portal through our VPN (firewall is Juniper SA4000) and using Internet Explorer (6, 7, and 8) and try to export any SSRS report under Excel, we get an error message: Internet Explorer cannot download . Internet Explorer was not able to open the internet site. The requested site is either unavailable or cannot be found. Please try again later. When not using the VPN (LAN from the office), everything (exporting under Excel) works fine. When using Firefox through the VPN, it works fine. When exporting to any other format (pdf or text or whatever), everything is fine under both IE and FF. Our firewall people suspect something in SSRS/MOSS/Office. Our MOSS consultants suspect something in the firewall Juniper SA4000. When using Fiddler and when not connected through VPN, I see the following traffic once i click on the "Export button": (Response was a request for client credentials) GET /ReportServer/Reserved.ReportViewerWebControl.axd?ExecutionID=j1pqbvbqkb34qf45fhlgnx55&ControlID=733607a7d607476abb1e6b8794202158&Culture=127&UICulture=9&ReportStack=1&OpType=Export&FileName=Product+Application+Report&ContentDisposition=OnlyHtmlInline&Format=EXCEL HTTP/1.1 Accept: */* Accept-Language: en-US,fr-be;q=0.5 User-Agent: Mozilla/4.0 (compatible;

  • Git subtree not properly using .gitignore when doing a partial clone

    - by D W
    I am a graduate student with many scripts, bibliography data in bibtex, thesis draft in latex, presentations in open office, posters in scribus, and figures and result data. I would like to put everything in one project under version control. Then when I need to work on a portion such as the bibliography data, I would like to check that subdirectory out, modify it as necessary and merge it back.I would like the ability to check out one version to my home computer, and a different one to my work computer and make changes to each independently and eventually merge them back. I would also like to be able to check out a piece of code from this big project and import it with versioning into a separate project. If I may changes I'd like to be able to merge them back to the original project. Based on my understanding git subtree can do this. http://github.com/apenwarr/git-subtree There is an example that is along the lines of what I'm trying to do at: http://psionides.jogger.pl/2010/02/04/sharing-code-between-projects-with-git-subtree/ Say the trunk of my project contained the directories: (bib bin cfg data fig src todo). When I use git subtree split -P bib -b export git checkout export I get a the bib directory, plus all files that should have been ignored or considered binary based on .gitignore such as the src directory and everything in it that ends in a tilde or the ./data directory. dwickrama@DWwork:~/research/trunk$ ls * -r biblography.bib JabRef src: script1.sh~ README~ script2.sh~ script3.sh~ script4.R~ script5.awk~ script5.py~ cfg: cfgFile1.ini~ cfgFile2.ini~ cfgFile3.ini~ bin: bigBinaryPackage1 bigBinaryPackage2 dwickrama@DWwork:~/research/trunk$ My .gitignore file is as follows: *.doc diff=word *.tex diff=tex *.bib diff=bibtex *.py diff=python *.eps binary *.jpg binary *.png binary ./bin/* binary *~ How do I prevent this?

  • Android - Using PreferenceScreen to display and save settings to/from ContentProvider

    - by Donal Rafferty
    I have my own custom Content Provider that loads a datasbase which contains the settings information for my application. I load the settings from the ContentProvider on the creation of my Settings activity. My Settings activity is made up of a PreferenceScreen and Dialog based EditText's. The following code shows how I use the preference screen and edit texts. So as you can see from the first image this works and displays the menu with the information underneath. The problem is in image two, when I click on a choice in the menu the dialog pops up but it is empty, I would like to be able to load the data from my content provider into the edit text in the dialog, so in image one it shows "Donal" as the user name so in image two "Donal" should also appear in the edit text in the dialog. I would also like to be able to listen to the OK button in the dialog so when a user changes a setting I can update the data in my content provider. Can anyone help me with what I'm trying to do? Code // Root PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this); // Dialog based preferences PreferenceCategory dialogBasedPrefCat = new PreferenceCategory(this); dialogBasedPrefCat.setTitle(R.string.dialog_based_preferences); root.addPreference(dialogBasedPrefCat); // Edit text preference EditTextPreference editTextPref = new EditTextPreference(this); editTextPref.setDialogTitle(R.string.dialog_title_edittext_preference); editTextPref.setKey("edittext_preference"); editTextPref.setTitle(R.string.title_edittext_preference); editTextPref.setSummary(name); dialogBasedPrefCat.addPreference(editTextPref); Image One Image Two

  • shouldAutorotateToInterfaceOrientation called several times in a row without any rotation

    - by Mike
    I am trying to implement some interface changes in my app, based on the device rotation. My app is a view based app. So, its main view controller has a didload method. The app starts in portrait. Almost all changes on the device orientation triggers the shouldAutorotateToInterfaceOrientation method but this method is not called when the device is put on portrait, after coming from any landscape orientation. While debugging the app, I have put a NSLog(@"orientation=%d", interfaceOrientation); on my shouldAutorotateToInterfaceOrientation method, and what I see is quite strange: When I run the app, shouldAutorotateToInterfaceOrientation is called 6 times before the app's interface even appears. Every time it runs, it reports a different number for the orientation: the order it reports on console is: portrait, portrait, portrait, landscape right, landscape left, upside down) (????). During this time the app is just beginning. All 6 times the debugger reports the method being run by the app's delegate. So, here comes the questions: WHy shouldAutorotateToInterfaceOrientation is not being called when the device enters on portrait? Why is this method running 6 times called by the delegate even before the app starts and shows its interface if no rotation is being done? thanks.

  • WCF, Metadata and BIGIP - Can I force the correct url for the WSDL items?

    - by Yossi Dahan
    We have a WCF service hosted on ServerA which is a server with no-direct Internet access and has a non-Internet routable IP address. The service is fronted by BIGIP which handles SSL encryption and decryption and forwards the unencrypted request to ServerA (at the moment it does NOT actually do any load balancing, but that is likely to be added in the future) on a specific port. What that means is that our clients would be calling the service through https://www.OurDomain.com/ServiceUrl and would get to our service on http://SeverA:85/ServiceUrl through the BIGIP device; When we browse to the WSDL published on https://www.OurDomain.com/ServiceUrl all the addresses contained in the WSDL are based on the http://SeverA:85/ServiceUrl base address We figured out that we could use the host headers setting to set the domain, but our problem is that while this would sort out the domain, we would still be using the wrong scheme – it would use http://www.OurDomain.com/ServiceUrl while we need it to be Https. Also – as we have other services (asmx based) hosted on that server we had some issues setting the host headers, and so we thought we could get away with creating another site on the server (using, say, port 82) and set the host header on that; now, on top of the http/https problem we have an issue as the WSDL contains the port number in all the urls, where BigIP works on port 443 (for the SSL) Is there a more flexible solution than implementing Host Headers? Ideally we need to retain flexibility and ease of supportability. Thanks for any help…

  • SHA512 vs. Blowfish and Bcrypt

    - by Chris
    I'm looking at hashing algorithms, but couldn't find an answer. Bcrypt uses Blowfish Blowfish is better than MD5 Q: but is Blowfish better than SHA512? Thanks.. Update: I want to clarify that I understand the difference between hashing and encryption. What prompted me to ask the question this way is this article, where the author refers to bcrypt as "adaptive hashing" http://chargen.matasano.com/chargen/2007/9/7/enough-with-the-rainbow-tables-what-you-need-to-know-about-s.html Since bcrypt is based on Blowfish, I was led to think that Blowfish is a hashing algorithm. If it's encryption as answers have pointed out, then seems to me like it shouldn't have a place in this article. What's worse is that he's concluding that bcrypt is the best. What's also confusing me now is that the phpass class (used for password hashing I believe) uses bcrypt (i.e. blowfish, i.e. encryption). Based on this new info you guys are telling me (blowfish is encryption), this class sounds wrong. Am I missing something?

  • codingBat repeatEnd using regex

    - by polygenelubricants
    I'm trying to understand regex as much as I can, so I came up with this regex-based solution to codingbat.com repeatEnd: Given a string and an int N, return a string made of N repetitions of the last N characters of the string. You may assume that N is between 0 and the length of the string, inclusive. public String repeatEnd(String str, int N) { return str.replaceAll( ".(?!.{N})(?=.*(?<=(.{N})))|." .replace("N", Integer.toString(N)), "$1" ); } Explanation on its parts: .(?!.{N}): asserts that the matched character is one of the last N characters, by making sure that there aren't N characters following it. (?=.*(?<=(.{N}))): in which case, use lookforward to first go all the way to the end of the string, then a nested lookbehind to capture the last N characters into \1. Note that this assertion will always be true. |.: if the first assertion failed (i.e. there are at least N characters ahead) then match the character anyway; \1 would be empty. In either case, a character is always matched; replace it with \1. My questions are: Is this technique of nested assertions valid? (i.e. looking behind during a lookahead?) Is there a simpler regex-based solution?

  • iPod/iPhone OpenGL ES UIView flashes when updating

    - by Dave Viner
    I have a simple iPhone application which uses OpenGL ES (v1) to draw a line based on the touches of the user. In the XCode Simulator, the code works perfectly. However, when I install the app onto an iPod or iPhone, the OpenGL ES view "flashes" when drawing the line. If I disable the line drawing, the flash disappears. By "flash", I mean that the background image (which is an OpenGL texture) disappears momentarily, and then reappears. It appears as if the entire scene is completely erased and redrawn. The code which handles the line drawing is the following: renderLineFromPoint:(CGPoint)start toPoint:(CGPoint)end { static GLfloat* vertexBuffer = NULL; static NSUInteger vertexMax = 64; NSUInteger vertexCount = 0, count, i; //Allocate vertex array buffer if(vertexBuffer == NULL) vertexBuffer = malloc(vertexMax * 2 * sizeof(GLfloat)); //Add points to the buffer so there are drawing points every X pixels count = MAX(ceilf(sqrtf((end.x - start.x) * (end.x - start.x) + (end.y - start.y) * (end.y - start.y)) / kBrushPixelStep), 1); for(i = 0; i < count; ++i) { if(vertexCount == vertexMax) { vertexMax = 2 * vertexMax; vertexBuffer = realloc(vertexBuffer, vertexMax * 2 * sizeof(GLfloat)); } vertexBuffer[2 * vertexCount + 0] = start.x + (end.x - start.x) * ((GLfloat)i / (GLfloat)count); vertexBuffer[2 * vertexCount + 1] = start.y + (end.y - start.y) * ((GLfloat)i / (GLfloat)count); vertexCount += 1; } //Render the vertex array glVertexPointer(2, GL_FLOAT, 0, vertexBuffer); glDrawArrays(GL_POINTS, 0, vertexCount); //Display the buffer [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } (This function is based on the function of the same name from the GLPaint sample application.) For the life of me, I can not figure out why this causes the screen to flash. The line is drawn properly (both in the Simulator and in the iPod). But, the flash makes it unusable. Anyone have ideas on how to prevent the "flash"?

  • WPF - How to bind a DataGridTemplateColumn

    - by Andy T
    Hi, I am trying to get the name of the property associated with a particular DataGridColumn, so that I can then do some stuff based on that. This function is called when the user clicks context menu item on the column's header... This is fine for the out-of-the-box ready-rolled column types like DataGridTextColumn, since they are bound, but the problem is that some of my columns are DataGridTemplateColumns, which are not bound. private void GroupByField_Click (object sender, RoutedEventArgs e){ MenuItem mi = (MenuItem)sender; ContextMenu cm = (ContextMenu) mi.Parent; DataGridColumnHeader dgch = (DataGridColumnHeader) cm.PlacementTarget; DataGridBoundColumn dgbc = (DataGridBoundColumn) dgch.Column; Binding binding = (Binding) dgbc.Binding; string BoundPropName = binding.Path.Path; //Do stuff based on bound property name here... } So, take for example my 'Name' column... it's a DataGridTemplateColumn (since it has an image and some other stuff in there). Therefore, it is not actually bound to the 'Name' property... but I would like to be, so that the above code will work. My question is two-part, really: 1) Is it possible to make a DataGridTemplateColumn be BOUND, so that the above code would work? Can I bind it somehow to a property? 2) Or do I need to something entirely different, and change the code above? Thanks in advance! AT

  • Coding a parser for a domain specific language in Java

    - by Bruno Rothgiesser
    We want to design a simple domain specific language for writing test scripts to automatically test a XML-based interface of one of our applications. A sample test would be: Get an input XML file from network shared folder or subversion repository Import the XML file using the interface Check if the import result message was successfull Export the XML corresponding to the object that was just imported using the interface and check if it correct. If the domain specific language can be declarative and its statements look as close as my sentences in the sample above as possible, it will be awesome because people won't necessarily have to be programmers to understand/write/maintain the tests. Something like: newObject = GET FILE "http://svn/repos/template1.xml" reponseMessage = IMPORT newObject newObjectID = GET PROPERTY '/object/id/' FROM responseMessage (..) But then I'm not sure how to implement a simple parser for that languange in Java. Back in school, 10 years ago, I coded a language parser using Lex and Yacc for the C language. Maybe an approach would be to use some equivalent for Java? Or, I could give up the idea of having a declarative language and choose an XML-based language instead, which would possibly be easier to create a parser for? What approach would you recommend?

  • Algorithms for City Simulation?

    - by anon
    I want to create a city filled with virtual creatures. Say like Sim City, where each creature walks around, doing it's own tasks. I'd prefer the city to not 'explode' or do weird things -- like the population dies off, or the population leaves, or any other unexpected crap. Is there a set of basic rules I can encode each agent with so that the city will be 'stable'? (Much like how for physics simulations, we have some basic rules that govern everything; is there a set of rules that governs how a simulation of a virtual city will be stable?) I'm new to this area and have no idea what algorithms/books to look into. Insights deeply appreciated. Thanks!

  • CPUID on Intel i7 processors

    - by StarPacker
    I'm having an issue with my CPUID-based code on newer i7-based machines. It is detecting the CPU as having a single core with 8 HT units instead of 4 cores each with 2 HT units. I must be misinterpreting the results of the CPUID information coming back from the CPU, but I can't see how. Basically, I iterate through each processor visible to Windows, set thread affinity to that thread and then make a sequence of CPUID calls. args = new CPUID_Args(); args.eax = 1; executeHandler(ref args); if (0 != (args.edx & (0x1 << 28))) { //If the 28th bit in EDX is flagged, this processor supports multiple logical processors per physical package // in this case bits 23:16 of EBX should give the count. //** EBX here is 0x2100800 logicalProcessorCount = (args.ebx & 0x00FF0000) >> 16; //** this tells me there are 16 logical processors (wrong) } else { logicalProcessorCount = 1; } apic = unchecked((byte)((0xFF000000 & args.ebx) >> 24)); if (maximumSupportedCPUID >= 4) { args = new CPUID_Args(); args.eax = 4; executeHandler(ref args); //EAX now contains 0x1C004121 coreCount = 1 + ((args.eax & 0xFC000000) >> 26); //This calculates coreCount as 8 } else { coreCount = 1; } This sequence repeats for the remainder of the CPUs in the system. Has anyone faced this before?

  • Binding update adds news series to WPF Toolkit chart (instead of replacing/updating series)

    - by Mal Ross
    I'm currently recoding a bar chart in my app to make use of the Chart class in the WPF Toolkit. Using MVVM, I'm binding the ItemsSource of a ColumnSeries in my chart to a property on my viewmodel. Here's the relevant XAML: <charting:Chart> <charting:ColumnSeries ItemsSource="{Binding ScoreDistribution.ClassScores}" IndependentValuePath="ClassName" DependentValuePath="Score"/> </charting:Chart> And the property on the viewmodel: // NB: viewmodel derived from Josh Smith's BindableObject public class ExamResultsViewModel : BindableObject { // ... private ScoreDistributionByClass _scoreDistribution; public ScoreDistributionByClass ScoreDistribution { get { return _scoreDistribution; } set { if (_scoreDistribution == value) { return; } _scoreDistribution = value; RaisePropertyChanged(() => ScoreDistribution); } } However, when I update the ScoreDistribution property (by setting it to a new ScoreDistribution object), the chart gets an additional series (based on the new ScoreDistribution) as well as keeping the original series (based on the previous ScoreDistribution). To illustrate this, here are a couple of screenshots showing the chart before an update (with a single data point in ScoreDistribution.ClassScores) and after it (now with 3 data points in ScoreDistribution.ClassScores): Now, I realise there are other ways I could be doing this (e.g. changing the contents of the original ScoreDistribution object rather than replacing it entirely), but I don't understand why it's going wrong in its current form. Can anyone help?

  • Ideas for OpenSource CMS in ASP.NET MVC

    - by rajesh pillai
    I am in the process of collecting ideas for building an opensource CMS based on ASP.net framework. I have choosen ASP.NET MVC with Jquery as the tool to develop this. I have made this as community wiki. Background: Most of the good CMS that is available is built on PHP, though off late CMS built on ASP.net framework seems to be cropping up. I would like to collect ideas/suggestion/expectations from an opensource CMS system for ASP.net platform. I am looking for expectation from technology and features that you wish could find in a modern CMS and any other thoughts/ideas that comes to your mind. Your input would be of great help in this direction. Meanwhile I am also reviewing many opensource CMS system built on ASP.net as well as MS Office Sharepoint to get ideas and I would update my findings here for your reference. The following are some of the opensource CMS/BlogEngines that I am in the process of reviewing. -Oxite (ASP.net MVC) : This is the new kid on the block -Wordpress -BlogEngine.net -Umbraco Some of the features that I can think of is noted below Simplified content creation Support Multiple content author Metadata feature Workflow engine Simplified deployment List based contents (sharepoint like) Customizable URL's Support content Caching Roles (contenauthor, contentpublisher etc) Support different types of content (like html, txt, document, image, videos) Skinnable (support extensible themes) Localization & Globalization Unlimited nesting of categories Readymade template for blog, forums,survey. Good documentation You can add your points or add some depth to any of the above feature.

  • Suggestions for doing async I/O with Task Parallel Library

    - by anelson
    I have some high performance file transfer code which I wrote in C# using the Async Programming Model (APM) idiom (eg, BeginRead/EndRead). This code reads a file from a local disk and writes it to a socket. For best performance on modern hardware, it's important to keep more than one outstanding I/O operation in flight whenever possible. Thus, I post several BeginRead operations on the file, then when one completes, I call a BeginSend on the socket, and when that completes I do another BeginRead on the file. The details are a bit more complicated than that but at the high level that's the idea. I've got the APM-based code working, but it's very hard to follow and probably has subtle concurrency bugs. I'd love to use TPL for this instead. I figured Task.Factory.FromAsync would just about do it, but there's a catch. All of the I/O samples I've seen (most particularly the StreamExtensions class in the Parallel Extensions Extras) assume one read followed by one write. This won't perform the way I need. I can't use something simple like Parallel.ForEach or the Extras extension Task.Factory.Iterate because the async I/O tasks don't spend much time on a worker thread, so Parallel just starts up another task, resulting in potentially dozens or hundreds of pending I/O operations; way too much! You can work around that by Waiting on your tasks, but that causes creation of an event handle (a kernel object), and a blocking wait on a task wait handle, which ties up a worker thread. My APM-based implementation avoids both of those things. I've been playing around with different ways to keep multiple read/write operations in flight, and I've managed to do so using continuations that call a method that creates another task, but it feels awkward, and definitely doesn't feel like idiomatic TPL. Has anyone else grappled with an issue like this with the TPL? Any suggestions?

  • UINavigationController with UIView and UITableView

    - by Tobster
    I'm creating a navigation-based app which displays a graph, rendered with openGL, and a tableview listing disclosure buttons of all of the elements that are displayed on the graph, and a settings disclosure button. The navigation controller is also a tableview delegate and datasource, and the tableview is added to the view programatically and has its' delegate and datasource set to 'self'. The OpenGL based graph view is added via IB. The problem I'm having is that I'm trying to push a view controller (either settings or graph element properties) within the didSelectRowAtIndexPath method. The method registers and the new view is pushed on, but the tableview stays and obscures part of the view that was pushed on, as if it has a different navigation controller. I can't seem to set the tableview's navigation controller to be the same as the rest of the UINavigationControllers' view. Does anyone know how I could fix this? My navigation controllers' initWithCoder method, where the tableview is added, appears as follows: elementList = [[UITableView alloc] initWithFrame:tableFrame style:UITableViewStyleGrouped]; elementList.dataSource = self; elementList.delegate = self; [self.view addSubview:elementList]; Further in the source file, the DidSelectRowAtIndexPath method where the navigation controller is pushed appears as follows: Settings* Controller = [[Settings alloc] init]; [self pushViewController:Controller animated:YES]; [Controller release];

  • Client-Side script to upload attachments to the Sharepoint 2007 list

    - by Clone of Anton Makrushin
    Hello. I have no good script-writing experience. So, I have a list created on MOSS 2007 with about 1000 elements and attachments enabled. I need to attach to each list item file (*.jpg) from a local folder. I doesn't have administrator privileges at MOSS server, only contributor rights Here is my script: $web = new-Object system.Net.WebClient $web.Credentials = [System.Net.CredentialCache]::DefaultCredentials $web.Headers.Add("user-agent", "PowerShell Script") $web.UploadFile('http://ruglbsrvsps/IT/Lists/Test1/', 'C:\temp\Attachments\14\Img1.jpg' ) Test1 - target list; Item1, Item2, Item3 - list items, without attachments, created manually When I run script, it returns byte array and does not upload file to the list item. Can you fix my script or advice better solution for my task (attach bulk of files to the MOSS list items, only contributor rights for target Sharepoint 2007 list) Thank you.

  • Is there a list of known web crawlers?

    - by J. Pablo Fernández
    I'm trying to get accurate download numbers for some files on a web server. I look at the user agents and some are clearly bots or web crawlers, but many for many I'm not sure, they may or may not be a web crawler and they are causing many downloads so it's important for me to know. Is there somewhere a list of know web crawlers with some documentation like user agent, IPs, behavior, etc? I'm not interested in the official ones, like Google's, Yahoo's, or Microsoft's. Those are generally well behaved and self-indentified.

  • GWT Best Practices - MVP

    - by GWTNewbie
    A question for all the GWT gurus out there. I'm a newbie in GWT and am trying to understand the best practices of coding a GWT application. I have gone through "Large scale application development and MVP" based on Ray Ryan's talk at Google I/O 2009 and it has given me a good starting point. I downloaded the sample source code as well for the Contacts application based on the best practices listed. The application I'm trying to develop using GWT is a bit bigger (in terms of the modules involved) when compared to the sample "Contacts" application & so I want to split it up into multiple functions. I have been reading that having a single Entry point in a GWT application is a good idea, and I don't want to dump all the code in one single AppController class & one single RpcService, what would be the best approach in this situation? How would I go about dispatching the control to multiple controllers? Is there a way to achieve this using some classes in the GWT framework?

  • Maven deploy:deploy-file not found due to version/timestamp appended to jar

    - by JamesC
    I'm having a problem using deploy:deploy-file with snapshots I'd like some advice on please. I have 2 projects; 1) Ant based and 2) the other Maven based that consumes the jars of the other project via Archiva. I've added a target to the Ant project to deploy snapshots on every successful build during our iteration. The problem is the Maven project cannot find them because the name of the dependency has a timestamp appended like so: someJar-1.0-20100407.171211-1.jar Here is the Ant target: <exec executable="${maven.bin}" dir="../lib"> <arg value="deploy:deploy-file" /> <arg value="-DgroupId=com.my.package" /><arg value="-DartifactId=${ant.project.name}" /> <arg value="-Dversion=${manifest.implementation.version}-SNAPSHOT" /> <arg value="-Dpackaging=jar" /> <arg value="-Dfile=../lib/${ant.project.name}-${manifest.implementation.version}-SNAPSHOT.jar" /> <arg value="-Durl=http://archiva.xxx.com/archiva/repository/snapshots" /> <arg value="-DrepositoryId=snapshots" /> </exec> I have a similar Ant target for releases and this works fine. Other pure Maven projects which deploy snapshosts via mvn deploy work fine. Does anyone know where I am going wrong? Thank You Update Figured out the answer, see below.
