• Web Deployment Projects for VS2010 on build server failing with Error MSB4086

  - by SteveBering

  When I upgraded my Web Deployment Project from VS2008 to the VS2010 beta version, I was able to execute the build locally on my development box. However, when I tried to execute the build on our TeamCity build server, I began getting the following exception: C:\Program Files\MSBuild\Microsoft\WebDeployment\v10.0\Microsoft.WebDeployment.targets(162, 37): error MSB4086: A numeric comparison was attempted on "$(_SourceWebProjectPath.Length)" that evaluates to "" instead of a number, in condition "'$(_SourceWebProjectPath)' != '' And $(_SourceWebProjectPath.Length) >= 4)". I did install the Web Deployment Project addin on my build server and I did copy over the C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications directory on my development box to the C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\ directory on the build server. Note: My dev box is 64bit and the build server 32bit. I can't figure out why this is behaving differently on the build server than on my dev machine. Anyone have any ideas? Thanks, Steve

• How can I export images from MS SQL Server to a file on disk?

  - by rball

  I have a User table that has all of their avatars saved in an image field. I'd like to just take that out of the database and store it as a regular file on disk. I looked around and saw some code for textcopy, but that doesn't seem to be on my machine for some reason. Here is the code I wrote up anyway. Anyone know a way to get this done? DECLARE @exec_str varchar (255) SELECT @exec_str = 'textcopy /S (local)\SQLEXPRESS' + --' /U ' + @login + --' /P ' + @password + ' /D thedatabase' + ' /T User'+ ' /C AvatarImage' + ' /F "d:\Avatars\' + User.Name + '.jpg"' + ' /O' FROM [User] WHERE UserID = 2 EXEC master..xp_cmdshell @exec_str

• libcurl .NET does not want to work on Win64

  - by Dmitry

  I wrote multi-threaded FTP uploader on C#.NET using libcurl.NET. Everything works fine on my machine, but when I give application (exe + libcurl.dll + 2 libcurl C# binding DLLs) to my friend who is running Win64, application crashes. After adding exception catcher to whole Main() function, I was able to get readable error message: "An attempt was made to load a program with an incorrect format (Exception from HRESULT = 0x8007000b)" After googling for a while, I found an advice to enable unmanaged code in my project settings. I've recompiled my application and LibCurlNet.dll with this flag set but it did not help. What can cause such problem?

• Ever any performance different between Java >> and >>> right shift operators?

  - by Sean Owen

  Is there ever reason to think the (signed) and (unsigned) right bit-shift operators in Java would perform differently? I can't detect any difference on my machine. This is purely an academic question; it's never going to be the bottleneck I'm sure. I know: it's best to write what you mean foremost; use for division by 2, for example. I assume it comes down to which architectures have which operations implemented as an instruction.

• Container Options in AWS Elastic Beanstalk

  - by Sangram Anand

  We have deployed a java webapplication in Elastic Beanstalk with the minimum instance count 1 and max instance count 2 for Autoscaling. The custom AMI we are using is c1.medium with Sun JDK 6. The environment status changed to yellow and then red. After checking into the log file from the snapshot logs we found a exception - Caused by: java.lang.OutOfMemoryError: Java heap space. Assuming this could be one of the possible reason for the Environment failure. The settings that we have configured in the Environment Container option are Initial JVM Heap Size (MB) - 256M Maximum JVM Heap Size (MB) - 512m The maximum heap size the java virtual machine will ever consume, specified on the JVM launch command line using -Xmx. Maximum JVM Permanent Generation Size (MB) - 512m Should i increase the Heap size from 512m to more or is it fine.

• Is there any killer application for Ontology/semantics/OWL/RDF yet?

  - by narnirajesh

  Hi Guys, I got interested in semantic technologies after reading a lot of books, blogs and articles on the net saying that it would make data machine-understandable, allow intelligent agents make great reasoning, automated & dynamic service composition etc.. I am still reading the same stuff from 2 years. The number of articles/blogs/semantic-conferences have increased considerably. But I am still unable to see any killer-application. Why is it so? Or is there some application/product (commercial/open-source) already existing, which actually is doing all that being boasted of? To put it more precisely, is there any product that leverages semantic technologies (esp RDF/OWL/SPARQL) and is delivering functionality/performance/maintainability, which would not have been possible with the existing (no-semantic) technologies? Some product that is completely dependent on semantic technologies and really adds value to the customers and generating revenues?

• Trying to INstall PHP on windows 7 ultimate with IIS6

  - by Jack

  I am trying to install php on my windows 7 machine. I have installed IIS 6.x and I have also installed php. I used this tutorial http://blogs.iis.net/bills/archive/2006/09/19/How-to-install-PHP-on-IIS7-_2800_RC1_2900_.aspx The only thing I didnt understand is this part: 4) Install IIS7, making sure you install the ISAPI Extension component (for PHP-ISAPI - which is what I use) or the CGI component (if you prefer CGI) during IIS installation (ISAPI and CGI are not installed by default) Now when i go to localhost I get an error. HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. 4: <handlers> 5: <add name="PHP" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\web\php5\php-cgi.exe" resourceType="Unspecified" /> 6: </handlers> Also php pages do not work in IE, please help

• Receiving "MERGE" 200 OK error when committing using trac-post-commit-hook

  - by Lyon Blecher

  When running a commit with the trac-post-commit-hook I receive a MERGE 200 OK error, I understand that this means that the commit has succeeded on the server but the file status has not updated on my local machine. But I can't find anyway to fix this issue. Would this be a problem with my setup or something in the script. I'm using stock standard script from the trac site, I'm committing through tortoiseSVN to VisualSVN Server which is hosted on a windows 2008 server. When I run the script through a command line I receive no errors, I only receive this error through TortoiseSVN.

On my local machine, i have my code open and in VS, i choose Debug-Attach for Qualifier i enter publicserver.com, but it tells me it cannot find it Questions: 1.) What port does remote debugging use? If i port sniff i dont see msvsmon.exe opening any new port ... Does it use 4015 by default? I dont think its a security thing, so please dont point me to the articles, i have followed them as much as i can, but they dont work for my scenerio (unless you find one i havent seen) Thanks :-)

• Can't get FCKEditor to work in a virtual directory.

  - by AngryHacker

  I have a WebForm that contains the following definition for the FCKeditor: <FCKeditorV2:FCKeditor ID="txtBody" runat="server" BasePath="/fckeditor/" Height="480px" ToolbarSet="WebCal1" > </FCKeditorV2:FCKeditor> This works fine in my VS2008-based web application. However, when I deploy it to a Virtual Directory in IIS, it looks for the FCKEditor files (e.g. javascript, stylesheets, etc...) in the /fckeditor folder, not in the /MyVirtualDir/fkceditor. I've tried changing the BasePath to ~/fckeditor/, but then it won't work on my dev machine. What is the right way to go, so that the FCKEditor maps onto the right directory. In my project the fckeditor directory is right off the root.

• Uploadify works for Visual Studio but not for IIS 7(same machines), using Forms authentication. Doe

  - by Marc

  I'm using the Uploadify jQuery control for client-side uploads. I think my IIS 7 configuration has issues with it. The uploadify POST immediately returns a HTTP 1.1 302 Found, back to my login page. I've tried to allow anonymous access to the uploading section(subfolder) plus the page(script) that processes the image in the web.config, using the location node(configuration ... location). Seems like the Uploadify post is immediately blocked. Again, this worked fine just using Visual Studio 2008, but when I run the site on the same machine I get the redirect. Your thoughts/ideas are very welcomed!

• Blend 4 breaks VS2010 for Silverlight

  - by Adrian

  Hi, I had VS2010 running fine with Silverlight development. Then I installed Expression Blend 4. Now when I run VS2010 and try to debug a silverlight app I get an error saying "Unable to start debugging. The silverlight developer runtime is not installed. Please install a matching version." I've tried uninstalling silverlight tools, and reinstalling them from scratch (the latest april version). But I still get the same message. So basically I'm now unable to do VS2010 SL development. I'm on the verge of just rolling back to my last system restore point and giving up on Blend. But if I do that I'd be worried that Product Activation would never allow me to reinstall it in the future, since the MSDN download page implies I'm only ever allowed to install it on a single machine. Any help appreciated. Thanks

• jQuery File Save As dialog for dynamic content

  - by DS

  Hi, I've a servlet that is invoked via jquery ajax. The resulting XML is then transformed using XSL and displayed on screen. Now, the requirement is to either print or save this content to the local machine. The print portion is working fine but I'm stuck at the Save As part. How do I do this using jquery/javascript? I'm using IE8/XP. I tried document.execCommand('SaveAs'); on button click but it doesn't seem to work in IE8. It shows the alerts I put in till that point, but doesn't bring up the dialog box. What's going wrong here?

• In a multithreaded app, would a multi-core or multiprocessor arrangement be better?

  - by Michael

  I've read a lot on this topic already both here (e.g., stackoverflow.com/questions/1713554/threads-processes-vs-multithreading-multi-core-multiprocessor-how-they-are or http://stackoverflow.com/questions/680684/multi-cpu-multi-core-and-hyper-thread) and elsewhere (e.g., ixbtlabs.com/articles2/cpu/rmmt-l2-cache.html or software.intel.com/en-us/articles/multi-core-introduction/), but I still am not sure about a couple things that seem very straightforward. So I thought I'd just ask. (1) Is a multi-core processor in which each core has dedicated cache effectively the same as a multiprocessor system (balanced of course for processor speed, cache size, and so on)? (2) Let's say I have some images to analyze (i.e., computer vision), and I have these images loaded into RAM. My app spawns a thread for each image that needs to be analyzed. Will this app on a shared cache multi-core processor run slower than on a dedicated cache multi-core processor, and would the latter run at the same speed as on an equivalent single-core multiprocessor machine? Thank you for the help!

• Problem sending mail with simple .net application. Server refusal error.

  - by Fatih

  I have a very simple .net application for testing SMTP on .net. But i am receiving this weird error. "System.Net.Mail.SmtpException: Failure sending mail. --- System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it" SMTP server is remote and doesn't need any kind of authentication so i don't need credentials. But i can send mails from this computer with outlook using same smtp server and same smtp settings without any problem. Any ideas? It will be appreciated so much. Imports System.Net.Mail Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim smtp As New SmtpClient smtp.Host = "10.241.128.220" smtp.Port = 25 smtp.Send("[email protected]", "[email protected]", "test", "test") End Sub

• Error connecting to online fossil repository after changing password.

  - by Toby Allen

  I set up a fossil repository on a shared hosting account I have. I created a perl script fossil.pl that points to a cloned repository that I put up on the webspace. I set all the correct permissions (755). When I go to fossil.pl I get the web ui. Everythings cool. However I'm having a problem with pushes and hoping someone could point me to a solution. When I clone a repository it sets a new password for me (Toby) in the new cloned repository. If I push to this repository online without changing the password it works fine, I can push up changes from my local machine to the online repository. However once I change the password for Toby (to something more easily remembered by me) I get the following error. Bytes Cards Artifacts Deltas Send: 1810 9 0 2 1Server Error: not authorized to write fossil: server says: not authorized to write Anyone know why this is happening? Anyone know how to fix it?

• Windows 2003 IIS FTP Server Migration w/ User Accounts

  - by Brad

  I'm trying to figure out the best way to migrate an FTP server from old hardware to new hardware. The server is on a domain, but not all the users setup on the server (to use FTP) are domain accounts, some are local to the server. For example, I have users both ways: domain\username machinename\username The new machine name will be different. So I need to copy all the files with permissions in tact from the old server to the new server. Then I need to convert all the user accounts from the old server to the new server. Then I need to change the file permissions so that they are no longer oldserver\username but newserver\username. Can this be accomplished all with CALCS? Is there an easy way that perhaps I'm missing?

• How do you get Client IP Address in Grails controller?

  - by Andrew

  I had code like this in Ruby @clientipaddress = request.env["HTTP_CLIENT_IP"] if (@clientipaddress == nil) @clientipaddress = request.env["HTTP_X_FORWARDED_FOR"] end if (@clientipaddress == nil) @clientipaddress = request.env["REMOTE_ADDR"] end if (@clientipaddress != nil) comma = @clientipaddress.index(",") if (comma != nil && comma >= 0) @clientipaddress = @clientipaddress[0, comma] end end It took care of all the possible ways that the ip might show up. For instance, on my local development machine there is no proxy. But in QA and Production the proxies are there and sometimes they provide more than one address. I don't need to know the groovy syntax. Just which methods get me the equivalent of the three different ways I ask for the ip above.

• How does the same origin policy apply to IP addresses

  - by recipriversexclusion

  I have a server on our company intranet that runs JBoss. I want to send API calls to this server from my machine, also on the intranet, and get the resulting XML responses using JQuery. I read the entry on Wikipedia but am confused how that applies to my situation, since our machines only have IP addresses, not domain names. I have server URL: 10.2.200.3:8001/serviceroot/service client IP address: 10.2.201.217 My questions are: As far as I understand these are different domains, right? So I have to use a proxy to issue JQuery.ajax calls to the server If I want to avoid doing (2), can I install Apache on the server and server the page with JS code form there? But then the JS will be from 10.2.200.3 and the server is at 10.2.200.3:8001. Aren't these considered different domains according to policy? Thanks!

I am aware of the incompatibilities between both versions and have dealt with it by applying the patch found here: http://www.zen-cart.com/forum/showthread.php?t=140960 I am able to login the admin side no problem, but when i navigate to the store - all i see are blank pages. How can I fix this issue? I'm hoping there is a fix elsewhere. Trying not to revert to an older PHP installation.

• IIS7 Custom Errror Handling Troubles for Classic ASP Website

  - by Eaphis

  I recently upgraded a web server from IIS6 to IIS7 for a classic asp application and now experience a bizarre error. In the IIS6 set up there was a custom 500-100 page that functioned properly by capturing errors and delivering an email with error code, error source and error type values. That same structure was set up on the IIS7 machine but now the error emails contain no error information at all. They all come through values such as 'NO SPECIFIC ERROR CODE', 'NO SPECIFIC ERROR DESCRIPTION', 'NO SPECIFIC ERROR SOURCE'. Any one have some thoughts on why my custom error page cannot capture the error information?
