• "The given key was not present in the dictionary" ASP.NET error on IIS7

  - by eugeneK

  Hi, i have this error on one of my sites. Searched thought all project found no Dictionary of some kind. Read somewhere it could be caused by Url Rewrite module on IIS 7 which i'm using for certain redirects. Error appears on all pages thought the site, 99% sure only on pages that use Url Rewriting This is error's stack at System.ThrowHelper.ThrowKeyNotFoundException() at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at System.Data.DataView.System.Collections.IList.get_Item(Int32 recordIndex) at System.Web.UI.WebControls.ListViewPagedDataSource.EnumeratorOnIList.get_Current() at System.Web.UI.WebControls.ListView.CreateItemsWithoutGroups(ListViewPagedDataSource dataSource, Boolean dataBinding, InsertItemPosition insertPosition, ArrayList keyArray) at System.Web.UI.WebControls.ListView.CreateChildControls(IEnumerable dataSource, Boolean dataBinding) at System.Web.UI.WebControls.ListView.PerformDataBinding(IEnumerable data) at System.Web.UI.WebControls.DataBoundControl.OnDataSourceViewSelectCallback(IEnumerable data) at System.Web.UI.WebControls.DataBoundControl.PerformSelect() at System.Web.UI.WebControls.ListView.PerformSelect() at System.Web.UI.WebControls.BaseDataBoundControl.EnsureDataBound() at System.Web.UI.WebControls.ListView.CreateChildControls() at System.Web.UI.Control.EnsureChildControls() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)HTTP_CONNECTION:Keep-Alive HTTP_ACCEPT:image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-icq, / HTTP_ACCEPT_LANGUAGE:en HTTP_COOKIE:__utma=248870149.1673016949.1252234176.1276449788.1276595165.49; __utmz=248870149.1276595165.49.55.utmcsr=search|utmccn=(organic)|utmcmd=organic|utmctr=???%20??; wooTracker=C1T8MWMAZWQVHJXWROHB25SO4S0B7UO0; __utmb=248870149.6.10.1276595165; __utmc=248870149; wooTracker=C1T8MWMAZWQVHJXWROHB25SO4S0B7UO0; machine-id=87.69.44.154%3A1253914747956; wooMeta=ODAwMzkmMSYxJjc1MDE5JjEyNTUyMTQwODEwMjkmMTI1NTIxNDE1NjA0OCYmMTAwJiYzMDAyODQmJiYm; _csoot=1267959625296; _csuid=X4c1ef311c39a67; ASP.NET_SessionId=zzdn5b45uqyhw145ptqhxe20 HTTP_HOST:**** HTTP_REFERER:***** HTTP_USER_AGENT:Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; GTB6) HTTP_X_CEPT_ENCODING:gzip, deflate ***** Is anyone familiar with fix or at least where to look for one ?

• Double Free inside of a destructor upon adding to a vector

  - by Shawn B

  Hey, I am working on a drum machine, and am having problems with vectors. Each Sequence has a list of samples, and the samples are ordered in a vector. However, when a sample is push_back on the vector, the sample's destructor is called, and results in a double free error. Here is the Sample creation code: class XSample { public: Uint8 Repeat; Uint8 PlayCount; Uint16 Beats; Uint16 *Beat; Uint16 BeatsPerMinute; XSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat); ~XSample(); void GenerateSample(); void PlaySample(); }; XSample::XSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat) { Beats = NewBeats; BeatsPerMinute = NewBPM; Repeat = NewRepeat-1; PlayCount = 0; printf("XSample Construction\n"); Beat = new Uint16[Beats]; } XSample::~XSample() { printf("XSample Destruction\n"); delete [] Beat; } And the 'Dynamo' code that creates each sample in the vector: class XDynamo { public: std::vector<XSample> Samples; void CreateSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat); }; void XDynamo::CreateSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat) { Samples.push_back(XSample(NewBeats,NewBPM,NewRepeat)); } Here is main(): int main() { XDynamo Dynamo; Dynamo.CreateSample(4,120,2); Dynamo.CreateSample(8,240,1); return 0; } And this is what happens when the program is run: Starting program: /home/shawn/dynamo2/dynamo [Thread debugging using libthread_db enabled] XSample Construction XSample Destruction XSample Construction XSample Destruction *** glibc detected *** /home/shawn/dynamo2/dynamo: double free or corruption (fasttop): 0x0804d008 *** However, when the delete [] is removed from the destructor, the program runs perfectly. What is causing this? Any help is greatly appreciated.

• SharpPcap issue

  This is my first time to use SharpPcap library. I created new project with VC# 2008 and I added SharpPcap as a reference to my project.

• emulator crashes

  - by Dave

  I am setting up an Android environment for the first time on Eclipse. I have many years of Eclipse experience, but new to Android. This is being done on an Apple Mac Mini, running MacOSX 10.6.3.

• How to completely wipe a previous ClickOnce installation?

  - by Dabblernl

  I have a curious problem: My app is distributed through ClickOnce. I recently installed three new clients on a new location. They worked. After an update however, all old clients worked fine, but the three new clients did not. As my code is swallowing an exception somewhere I have been unable thusfar to pinpoint where the error lies. When I XCopy the latest version of the app to the desktop of the three new client computers the program works fine. So, I thought uninstalling and reinstalling the program from the download location should fix the problem, but it does not! I can think of two explanations: The new location has some firewall/virusscanner in place that doesn't like the latest version of my app when it is run from a standard ClickOnce directory, but it allows execution from the desktop. Some old settings (the app uses user scoped and app scoped settings) remain in effect after the uninstall. When I find and check the user.config file for the app however, I find no incorrect setttings there. Thusfar, I have been unable to reproduce the error on any other machine. How can I solve this!?

• Database INSERT does not take place

  - by reggie

  My code is as follows: <?php include("config.php"); $ip=$_SERVER['REMOTE_ADDR']; if($_POST['id']) { $id=$_POST['id']; $id = mysql_escape_String($id); $ip_sql=mysql_query("select ip_add from Voting_IP where mes_id_fk='$id' and ip_add='$ip'"); $count=mysql_num_rows($ip_sql); if($count==0) { $sql = "update Messages set up=up+1 where mes_id='$id'"; mysql_query($sql); $sql_in = "insert into Voting_IP (mes_id_fk,ip_add) values ('$id','$ip')"; mysql_query($sql_in) or die(mysql_error()); echo "<script>alert('Thanks for the vote');</script>"; } else { echo "<script>alert('You have already voted');</script>"; } $result=mysql_query("select up from Messages where mes_id='$id'"); $row=mysql_fetch_array($result); $up_value=$row['up']; echo "<img src='button.png' width='110' height='90'>"; echo $up_value; } ?> My problem is that the insert process does not take place at all. The script tags echos an alert box. Even the img tag is echoed to the web page. But the insert process does not take place. The config file is fine. Note: This code works on my local machine which has PHP 5.3 but it does not work on the server which has PHP 5.2. Any advice?

• Really "wow" them in the interview

  - by Juliet

  Let me put it to you this way: I'm a top-notch programmer, but a notoriously bad interviewee. I've flunked 3 interviews consecutively because I get so nervous that my voice tightens at least 2 octaves higher and I start visibly shaking -- mind you, I can handle whatever technical questions the interviewer throws at me in that state, but I think it looks bad to come off as a quivering, squeaky-voiced young woman during a job interview. I've just got the personality type of a shy computer programmer. No matter how technical I am, I'm going to get passed up in favor of a smooth talker. I have another interview coming up shortly, and I want to really impress the company. Here are my trouble spots: What can I do to be less nervous during my interview? I always get really excited when I hear I have a face-to-face interview, but get more and more anxious as D-Day the interview approaches. My employers wants me to explain what I used to do at my prior employment. I'm a very chatty person and tend to talk/squeak for 10 minutes at a time. How long or short should I time my answers? On that note, when I'm explaining what I did at prior jobs, what exactly is my interviewer looking for? At some point, my interviewer will ask "do you have any questions for me while you're here?" I should, but what kinds of questions should I ask to show that I'm interested in being employed? My interviewer always asks why I'm looking for a new job. The real reason is that my present salary is $27K/yr [Edit to add: and I've yet to get a raise since I started], and I want to make more money -- otherwise the work environment is fine. How do I sugarcoat "I want to make more money" into something that sounds nicer? I have only one prior programmer job, and I've worked there for 18 months, but I have the skill of someone with 4 to 6 years of experience. What can I say to compete against applicants with more work experience? I took a low-paying $27K/yr programming job just to get my foot in IT, and I've been trying to leverage that job as a stepping stone to better opportunities. I get interviews because I consistently out-score senior-level developers in aptitude tests, and my desired salary range is right in the ballpark of what most companies want to offer. Unfortunately, while I've been a programming as a hobby for 10 years and I'm geared to graduate with my BA in Comp Sci in May '09, employers see me as a junior-level programmer with no degree. I want to prove them wrong and get a job that matches my skill level. I'd appreciate any advice anyone has to offer, especially if they can help me get a better job in the process.

• WCF Certificates without Certificate Store

  - by Kane

  My team is developing a number of WPF plug-ins for a 3rd party thick client application. The WPF plug-ins use WCF to consume web services published by a number of TIBCO services. The thick client application maintains a separate central data store and uses a proprietary API to access the data store. The thick client and WPF plug-ins are due to be deployed onto 10,000 workstations. Our customer wants to keep the certificate used by the thick client in the central data store so that they don't need to worry about re-issuing the certificate (current re-issue cycle takes about 3 months) and also have the opportunity to authorise the use of the certificate. The proposed architecture offers a form of shared secret / authentication between the central data store and the TIBCO services. Whilst I don’t necessarily agree with the proposed architecture our team is not able to change it and must work with what’s been provided. Basically our client wants us to build into our WPF plug-ins a mechanism which retrieves the certificate from the central data store (which will be allowed or denied based on roles in that data store) into memory then use the certificate for creating the SSL connection to the TIBCO services. No use of the local machine's certificate store is allowed and the in memory version is to be discarded at the end of each session. So the question is does anyone know if it is possible to pass an in-memory certificate to a WCF (.NET 3.5) service for SSL transport level encryption? Note: I had asked a similar question (here) but have since deleted it and re-asked it with more information.

• VS2008 adding SQL Server Database (SQL Server 2008 Mgmt Studio) not working

  - by Kahn

  I'm trying to practice using the ASP.Net MVC at home, but I ran into an impossible problem. I cannot open a connection to SQL Server 2008, I get this error: "Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly. ..." I've googled around for numerous responses, none of them either working or addressing this issue. I'm running Vista 32bit, my SQL Server 2008 Mgmt Studio is also 32bit, I have SP1 installed both on VS2008 Professional, as well as the SQL Server. I changed the machine.config connectionStrings from ./SQLExpress to my SQL Server 2008 name. Now if I connect manually through web.config, in an asp:datasource or code-behind, everything works fine. But for some reason trying to add a DB Connection directly like this always gets the error. This is pretty fatal, since I can't rightly do much unless I can use LINQ to SQL with my MVC test project, and this is the only way I know how. Worked fine in school and work, but not at home. Installing SQL Server Express 2005, as some have suggested, is not an option. Obviously it HAS to work with SQL Server 2008. Thanks in advance.

• Problem with ColdFusion communicating with MySQL database

  - by Greg

  Hi, I have been working to migrate a non-profit website from a local server (running Windows XP) to a GoDaddy hosting account (running Linux). Most of the pages are written in ColdFusion. Things have gone smoothly, up until this point. There is a flash form within the site (see this page: http://www.preservenet.cornell.edu/employ/submitjob.cfm) which, when completed, takes the visitor to this page: submitjobaction.cfm . I'm not quite sure what to make of this error, since I copied exactly what had been in the old MySQL database, and the .cfm files are exactly as they had been when they worked on the old server. Am I missing something? Below is the code from the database that the error seems to be referring to. When I change "Positionlat" to some default value in the database as it suggests in the error, it says that another field needs a default value, and it's a neverending chain of errors as I try to correct it. This is probably a stupid error that I'm missing, but I've been working at it for days and can't find what I'm missing. I would really appreciate any help.

• RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

  - by Ed

  I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

• MD5 Hashing Given a Key in C#

  - by Jared

  I've been looking for a way to hash a given string in C# that uses a predetermined key. On my adventures through the internet trying to find an example i have seen lots of MD5CryptoServiceProvider examples which seem to use a default key for the machine, but none of them that apply a specific key. I need to have a specific key to encode data as to synchronize it to someone else's server. I hand them a hashed string and an ID number and they use that analyze the data and return a similar set to me. So is there anyway to get md5 to hash via a specific key that would be consistent to both. I would prefer this to be done in C#, but if its not possible with the libraries can you do so with some web languages like php or asp? Edit: Misunderstood the scenario I was thrown into and after a little sitting and thinking about why they would have me use a key it appears they want a key appended to the end of the string and hashed. That way the server can appended the key it has along with the data passed to ensure its a valid accessing computer. Anyways... thanks all ^_^ Edit2: As my comment below says, it was the term 'salting' I was oblivious to. Oh the joys of getting thrown into something new with no directions.

• Configuring 32-Bit ASP.NET Application on a 64-Bit IIS Server

  - by Tim

  Hello, I’m trying to install a 32-bit ASP.NET application onto a 64-bit IIS server running on Windows Server 2008. This is a clean installation of the operating system with no other applications installed. As a prerequisite for our installation, we run the 32-bit version of aspnet_regiis –i It fails with the following message: The error indicates that IIS is not installed on the machine. Please install IIS before using this tool. Additionally: IIS is definitely installed. The 64 bit version of aspnet_regiis runs cleanly without warnings. “Enable 32 bit applications” is set to True in the DefaultAppPool’s Advanced Settings. The IIS Metabase and IIS 6 configuration compatibility” component is installed. We have a test VM where this error occurs as well as test VM where both the 32 bit and 64 bit versions of aspnet_regiis run without errors. We've had no luck distinguishing the differences between the two test VMs. We have struggled with this issue for several days to no avail. Any suggestions would be greatly appreciated!

  Hi, I created a very simple webservice in ASP.NET 2.0 to query a list in SharePoint 2007 like this: namespace WebService1 { /// <summary> /// Summary description for Service1 /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class Service1 : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { return "Hello World"; } [WebMethod] public string ShowSPMyList() { string username = this.User.Identity.Name; return GetList(); } private string GetList() { string resutl = ""; SPSite siteCollection = new SPSite("http://localhost:89"); using (SPWeb web = siteCollection.OpenWeb()) { SPList mylist = web.Lists["MySPList"]; SPQuery query = new SPQuery(); query.Query = "<Where><Eq><FieldRef Name=\"AssignedTo\"/><Value Type=\"Text\">Ramprasad</Value></Eq></Where>"; SPListItemCollection items = mylist.GetItems(query); foreach (SPListItem item in items) { resutl = resutl + SPEncode.HtmlEncode(item["Title"].ToString()); } } return resutl; } } } This web service runs well when tested using the built-in server of Visual Studio 2008. The username indicates exactly my domain account (domain\myusername). However when I create a virtual folder to host and launch this web service (still located in the same machine with SP2007), I got the following error when invoking ShowSPMyList() method, at the line to execute OpenWeb(). These are the details of the error: System.Data.SqlClient.SqlException: Cannot open database "WSS_Content_8887ac57951146a290ca134778ddc3f8" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Does anyone have any idea why this error happens? Why does the web service run fine inside Visual Studio 2008, but not when running stand-alone? I checked and in both cases, the username variable has the same value (domain\myusername). Thank you very much.

• VLC desktop streaming

  - by StackedCrooked

  Edit I stopped using VLC and switched to GMax FLV Encoder. It does a much better job IMO. Original post I am sending my desktop (screen) as an H264 video stream to another machine that saves it to a file using the follwoing command lines: Sender of the stream: vlc -I dummy --sout='#transcode{vcodec=h264,vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' Receiver of the stream: vlc -I rc rtp://@:4444 --sout='#std{access=file,mux=ps,dst=/home/user/output.mp4}' --ipv4 This works, but there are a few issues: The file is not playable with most players. VLC is able to playback the file but with some weirdness: = it takes about 10 seconds before the playback actually begins. = seeking doesn't work. Can someone point me in the right direction on how to fix these issues? EDIT: I made a little progress. The initial delay in playback is because the player is waiting for a keyframe. By forcing the sender of the stream to create a new key-frame every 4 seconds I could decrease the delay: :screen-fps=10 --sout='#transcode{vcodec=h264,venc=x264{keyint=40},vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' The seeking problem is not solved however, but I understand it a little better. The RTP stream is saved as a file in its original streaming format, which is normally not playable as a regular video file. VLC manages to play this file, but most other players don't. So I need to convert it to a regular video file. I am currently investigating whether I can do this with ffmpeg if I provide it with an SDP file for the recorded stream. All help is welcome!

• Activate a (COM Interop based) ActiveX contol using registration free com

  - by embnut

  I have a (COM Interop based) ActiveX contol that I am trying to use with registration free com. When the control loads the control is inactive (does not responds to events, control not fully rendered etc). After much search I discovered that COM objects using reg-free-com use the miscStatus attribute to set the initial state to get correctly activated. I know how to use it with a comClass which corresponds to a native COM Object. 1) What is the equivalent of the following for clrClass element which corresponds to a COM-interop object? <comClass clsid="{qqqqqqqq-wwww-eeee-rrrr-00C0F0283628}" tlbid="{xxxxxxxx-yyyy-zzzz-aaaa-0000F8754DA1}" threadingModel="Both" progid="SomeCompany.SomeOleControl" description="Some ActiveX Control" miscStatus="recomposeonresize,insideout,activatewhenvisible,nouiactivate" > 2) The COM client I am using is Visual FoxPro. If the (1) is not possible what can I do in VFP to activate the inactive ActiveX control. (I dont mind VB or C# input too if I can use it to find the equivalent foxpro) Currently I tried the following this.AddObject('OleControl1', 'oleControl', 'SomeCompany.SomeOleControl') this.OleControl1.AutoActivate = 3 this.OleControl1.Visible = .T. this.OleControl1.SetFocus But I the OleControl1 gets focus before passing events like mouse click to its subelements. So I have to click twice on it to do the necessary action, any time it does not have focus. I would like the control to act as if the "nouiactivate" of the miscStatus value is set. 3) Is there any other way of accomplishing what I want to do? Hans Passant, here is the listing of current Assembly.dll.manifest. The formatting in the comment made it unreadable. <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity name="Assembly" version="1.0.0.0" type="win32" publicKeyToken="wwwwwwwwwwwwwwww"/> <clrClass name="SomeCompany.SomeOleControl" clsid="{qqqqqqqq-wwww-eeee-rrrr-00C0F0283628}" progid="SomeCompany.SomeOleControl" threadingModel="Both"/> <file name="Assembly.tlb"> <typelib tlbid="{xxxxxxxx-yyyy-zzzz-aaaa-0000F8754DA1}" version="1.0" helpdir="" flags="hasdiskimage"/> </file> </assembly>

• How to compile a C DLL for 64 bit with Visual Studio 2010?

  - by Daren Thomas

  I have a DLL written in C in source code. This is the code for the General Polygon Clipper (in case you are interested). I'm using it in a C# project via the C# wrapper provided on the homepage. This comes with a precompiled DLL. Since switching to a 64bit Development machine with Visual Studio 2010 and Windows 7 64 bit, the application won't run anymore. This is the error I get: An attempt was made to load a program with an incorrect format. This is because of DLLImporting the 32bit gpc.dll, as I have gathered from stuff found on the web. I assume this will all go away if I recompile the DLL to 64bit, but can't for the love of me figure out how to do so. My C skills are basic, in that I can write a C program with the GNU tools, but have no experience with various compilers / processors / IDEs etc. I believe I could port this to C#. By that I mean I trust myself to actually pull it off. But I'd prefer not to, since it is a lot of work that I'd prefer a compiler to do for me ;)

• Installing mongrel service on Windows 2008

  - by akirekadu

  We use InstallAnywhere to install our product. One of the components that it needs to install is mongrel. IA invokes the following command line during installation: mongrel_rails service::install -N service-1 -D "Service 1" -c "C:\app_dir\\rails\rails_apps\service-1" -p 19000 -e production Apprently under the hoods "sc create..." is used. The installation works great on Windows 2003. On Windows 2008 though this operation requires elevated privileges. When I login as local administrator (ie 'local-machine\administrator' user), the installation works just fine. However, when I login as a domain user that is part of local administrators group, the services fails to install with error "access is denied". How can I make it possible to install the product without having to login as local administrator? Thanks! Couple of notes I would like to add. One solution I tried is to execute the installer as administrator. The service does get installed. However, it creates another problem. An embedded 3rd party product and its files get installed with admin only rights. So we do need to run the installer as logged in user.

• Cannot connect Linux XAMPP PHP to MS SQL database.

  - by Jim

  I've searched many sites without success. I'm using XAMPP 1.7.3a on Ubuntu 9.1. I have used the methods found at http://www.webcheatsheet.com/PHP/connect_mssql_database.php, they all fail. I am able to "connect" with a linked database through MS Access, however, that is not an acceptable solution as not all users will have Access. The first method (at webcheatsheet) uses mssql_connect, et.al. but I get this error from the mssql_connect() call: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: [my server] in [my code] [my server] is the server address, I have used both the host name and the IP address. [my code] is a reference to the file and line number in my .php file. Is there a log file somewhere that would have more information about the failure, both on my machine and the MS SQL server? We do not have a bona-fide DBA, so I will need specific information to pass on if the issue seems to be on the server side. All assistance is appreciated, including RTFM when the location of the M is provided! Thanks

• IIS6 configuration for WCF/Silverlight

  - by Grayson Mitchell

  I am trying the simple senario of running a WCF service to return Active directory information on a user. (http://rouslan.com/2009/03/20-steps-to-get-together-windows-authentication-silverlight-and-wcf-service/) using Silverlight 4 & .net 4 However, I am being driven insane by trying to set this up in IIS. Currently I have my solution working in VS, but when I try to run the service in ISS a debug window tries to open... (and I can't get rid of it, is is complaining about the WCF call). <basicHttpBinding> <binding name="winAuthBasicHttpBinding"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm"/> </security> </binding> </basicHttpBinding> The Insanity: I have got the IIS to successfully call a WCF service (but can't reproduce), I have created 5 projects to try and get this working, but in my 5th I can't even browse the site (says it can't download silverlight application, but mime type are setup). My next step is to install Server2008 on a test machine and try IIS7... as all the various walkthrough's I have found just dont seem to work in IIS6.

• IE and Content-disposition inline vs. extension-token

  - by pinkgothic

  Preamble So IE does Mime-Type sniffing. That part's old news. Suggestions of how to combat it tend to be along the lines of 'supply a content-type IE trusts' (i.e. anything that isn't text/plain or application/octet-stream) or 'add extraneous data at the start of the file that is definitely of the type you're serving'. Now, I'm working on an application that has to allow message attachments (like in e-mails), and we want to close up XSS vectors. IE's mime sniffing is one of those vectors - a text/plain file with html content will trigger as html. Recoding isn't an option at this point, changing the attachments the user has provided can only happen if there is absolutely no doubt about the maliciousness of the file - and someone might want to send HTML as text. Now, Microsoft's MSDN article implies the situation might be easier to fix than advertised: If Internet Explorer knows the Content-Type specified and there is no Content-Disposition data, Internet Explorer performs a "MIME sniff," [...] Great! Except I don't have IE nor current means to reliably install it (I realise this is a fairly sad state for a webdeveloper to be in, I hope to fix this soon) and this is grey theory that I can't quite seem to get confirmed one way or the other. Local sources say that line is hogwash - IE will mime sniff anything that is Content-Disposition: inline / <default> and not specific enough for its tastes in -Type. But what about x-* ('extension-token' in the RFC)? Trying to google for how browsers handle Content-Disposition: <extension-token> hasn't yielded anything (though I may just be doing it wrong, my understanding of Google is seriously slipping lately). I found one question that looked promising, but turned out to be a misunderstanding on side of the thread author, meaning that the train of thought was never actually addressed there. Question(s) Does IE really Mime sniff if you expressly pass Content-Disposition: inline? If so: Does anyone here know how browsers handle Content-Disposition: <extension-token>? If they do this in a way that is for my purposes benign, by presuming it to be synonymous with the default (effectively 'inline', though I hear it's not defined anywhere?), is it specific enough for IE not to Mime sniff? Or am I actually shooting myself in the foot by thinking of pursuing this avenue?

• VMWare steals IP addresses [closed]

  - by Ishan Amin

  I'm having a peculiar problem, that I think I have narrowed down to VMware. For the past one year, every once in a while we lose internet connection and not all users (about 10 users) go down at the same time, its usually one-by-one. First someone will call me and say "Internet is down" and then we would go reset the router and modem and switch and it would be working again for a while, then go down again without any pattern or replicatable sequence. We'd go repeat the steps again to get everyone in the office running again. We called our Internet Service Provider and they constantly say, We see your modem and we see your router and from thier end everything is OK. we replaced our router and switch and modem, twice! Last friday, it dawned upon me, that everytime we turn on a VMware machine, this sequence of taking everyone down starts, which also explains the message that my users get for "IP Conflict Found" So we do alot of VMware testing and lo and behold, it takes my Internet down. My Yahoo and Gtalk would continue working but www is down when the VMware machines are started. I do use bridged networking to all the VMware machines, but I dont know what else to set it at. now, sorry for this long rambling but anyone have any clue on how to stop this? thanks IA
