• Calling 32 bit unmanaged dlls from C# randomly failing

  - by Bert

  Hi, I'm having an issue when calling 32 bit delphi dll's from c# web site. The code generally runs fine, but occasionally I get an error Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). This issue persists until I recycle the app pool for the site, and then it works fine again. On the same server, there is also a web service that is calling the same set of dlls. This web service doesn't seem to have the same issue that the web site has. Both applications are using .net framework 3.5, separate app pools on IIS. Here is the code I'm using to wrap the dlls: public sealed class Mapper { static Mapper instance = null; [DllImport("kernel32.dll")] private static extern bool SetDllDirectory(string lpPathName); private Mapper() { SetDllDirectory(ConfigManager.Path); } public static Mapper Instance { get { if (instance == null) { instance = new Mapper(); } return instance; } } public int Foo(string bar, ref double val) { return Loader.Foo(bar, ref val); } } public static class Loader { [DllImport("some.dll", CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode, EntryPoint = "foo")] public static extern int Foo(string bar, ref double val); } Then I call it like this: double val = 0.0; Mapper.Instance.Foo("bar", ref val); Any ideas as to why it would "randomly" Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). The other problem is that I haven't been able to replicate the issue in the development environment. I thought that due to 2 applications calling the same dlls, that there could be some locks occurring. To replicate this, I created an app that spawned multiple threads and repeatedly called the 32bit dlls, and then used the web site to call these same dlls. I still couldn't replicate the issue. Some possible fixes that I can think of: Wrap the 32 bit dlls in web service (because the webservice doesn't seem to suffer from the same problem). But this may be worthless if it turns out that the web service also fails. Set up state server for the session state and periodically recycle the app pool for the site.This isn't fixing the problem, only avoiding it. Wrap the dll's in exe, and call that exe. Then I shouldn't get the same issue. But this also seems like a hacky solution. Implement the mapper class differently ? But how else should I be doing the call? The other draw back is that other applications are using this mapper, so I'd need to change there code too. Thanks

• If Then Statement Condition Being Ignored With Optimisations On

  - by Matma

  I think im going mad but can some show me what im missing, it must be some stupidly simple i just cant see the wood for the trees. BOTH side of this if then else statement are being executed? Ive tried commenting out the true side and moving the condition to a seperate variable with the same result. However if i explicitly set the condition to 1=0 or 1=1 then the if then statement is operating as i would expect. i.e. only executing one side of the equation... The only time ive seen this sort of thing is when the compiler has crashed and is no longer compiling (without visible indication that its not) but ive restarted studio with the same results, ive cleaned the solution, built and rebuilt with no change? please show me the stupid mistake im making using vs2005 if it matters. Dim dset As DataSet = New DataSet If (CboCustomers.SelectedValue IsNot Nothing) AndAlso (CboCustomers.SelectedValue <> "") Then Dim Sql As String = "Select sal.SalesOrderNo As SalesOrder,cus.CustomerName,has.SerialNo, convert(varchar,sal.Dateofpurchase,103) as Date from [dbo].[Customer_Table] as cus " & _ " inner join [dbo].[Hasp_table] as has on has.CustomerID=cus.CustomerTag " & _ " inner join [dbo].[salesorder_table] as sal On sal.Hasp_ID =has.Hasp_ID Where cus.CustomerTag = '" & CboCustomers.SelectedValue.ToString & "'" Dim dap As SqlDataAdapter = New SqlDataAdapter(Sql, FormConnection) dap.Fill(dset, "dbo.Customer_Table") DGCustomer.DataSource = dset.Tables("dbo.Customer_Table") Else Dim erm As String = "wtf" End If EDIT: i have found that this is something to do with the release config settings im using, i guesing its the optimisations bit. does anyone know of any utils/addons for vs that show if a line has been optimised out. delphi, my former language showed blue dots in the left margin to show that it was a compiled line, no dot meaning it wasnt compiled in, is there anything like that for vs? alternatively can someone explain how optimisations would affect this simple if statement causeing it to run both sides? EDIT2: using this thread as possible causes/solutions : http://stackoverflow.com/questions/2135509/bug-only-occurring-when-compile-optimization-enabled. It does the same with release = optimisations on, x86, x64 and AnyCPU Goes away with optimisations off. Im using V2005 on a x64 win7 machine, if that matters. Thanks

• Do NOT Change "Copy Local” project references to false, unless understand subsequences.

  - by Michael Freidgeim

  To optimize performance of visual studio build I've found multiple recommendations to change CopyLocal property for dependent dlls to false,e.g. From http://stackoverflow.com/questions/690033/best-practices-for-large-solutions-in-visual-studio-2008 CopyLocal? For sure turn this offhttp://stackoverflow.com/questions/280751/what-is-the-best-practice-for-copy-local-and-with-project-referencesAlways set the Copy Local property to false and enforce this via a custom msbuild stephttp://codebetter.com/patricksmacchia/2007/06/20/benefit-from-the-c-and-vb-net-compilers-perf/BenefitBenefitMy advice is to always set ‘Copy Local’ to falseSome time ago we've tried to change the setting to false, and found that it causes problem for deployment of top-level projects.Recently I've followed the suggestion and changed the settings for middle-level projects. It didn't cause immediate issues, but I was warned by Readify Consultant Colin Savage about possible errors during deploymentsI haven't undone the changes immediately and we found a few issues during testing.There are many scenarios, when you need to have Copy Local’ left to True.The concerns are highlighted in some stack overflow answers, but they have small number of votes.Top-level projects:  set copy local = true.First of all, it doesn't work correctly for top-level projects, i.e. executables or web sites.As pointed in the answer http://stackoverflow.com/a/6529461/52277for all the references in the one at the top set copy local = true.Alternatively you have to change output directory as it's described in http://www.simple-talk.com/dotnet/.net-framework/partitioning-your-code-base-through-.net-assemblies-and-visual-studio-projects/If you set ‘ Copy Local = false’, VS will, unless you tell it otherwise, place each assembly alone in its own .\bin\Debugdirectory. Because of this, you will need to configure VS to place assemblies together in the same directory. To do so, for each VS project, go to VS > Project Properties > Build tab > Output path, and set the Ouput path to ..\bin\Debugfor debug configuration, and ..\bin\Release for release configuration.Second-level  dependencies:  set copy local = true.Another example when copylocal =false fails on run-time, is when top level assembly doesn't directly referenced one of indirect dependencies.E..g. Top-level assembly A has reference to assembly B with copylocal =true, but assembly B has reference to assembly C with copylocal =false. Most likely assembly C will be missing on runtime and will cause errors E.g. http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1Copy local is important for deployment scenarios and tools. As a general rule you should use CopyLocal=True and http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1 Unfortunately there are some quirks and CopyLocal won't necessary work as expected for assembly references in secondary assemblies structured as shown below.MainApp.exe MyLibrary.dll ThirdPartyLibrary.dll (if in the GAC CopyLocal won't copy to MainApp bin folder)This makes xcopy deployments difficult . .Reflection called DLLs  dependencies:  set copy local = true.E.g user can see error "ISystem.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."The fix for the issue is recommended in http://stackoverflow.com/a/6200173/52277"I solved this issue by setting the Copy Local attribute of my project's references to true."In general, the problems with investigation of deployment issues may overweight the benefits of reduced build time. Setting the Copy Local to false without considering deployment issues is not a good idea.

• BizTalk Testing Series - The xpath Function

  - by Michael Stephenson

  Background While the xpath function in a BizTalk orchestration is a very powerful feature I have often come across the situation where someone has hard coded an xpath expression in an orchestration. If you have read some of my previous posts about testing I've tried to get across the general theme like test-driven or test-assisted development approaches where the underlying principle is that your building up your solution of small well tested units that are put together and the resulting solution is usually quite robust. You will be finding more bugs within your unit tests and fewer outside of your team. The thing I don't like about the xpath functions usual usage is when you come across an orchestration which has something like the below snippet in an expression or assign shape: string result = xpath(myMessage,"string(//Order/OrderItem/ProductName)"); My main issue with this is that the xpath statement is hard coded in the orchestration and you don't really know it works until you are running the orchestration. Some of the problems I think you end up with are: You waste time with lengthy debugging of the orchestration when your statement isn't working You might not know the function isn't working quite as expected because the testable unit around it is big You are much more open to regression issues if your schema changes     Approach to Testing The technique I usually follow is to hold the xpath statement as a constant in a helper class or to format a constant with a helper function to get the actual xpath statement. It is then used by the orchestration like follows. string result = xpath(myMessage, MyHelperClass.ProductNameXPathStatement); This means that because the xpath statement is available outside of the orchestration it now becomes testable in its own right. This means: I can test it in its own right I'm less likely to waste time tracking down problems caused by an error in the statement I can reduce the risk or regression issuess I'm now able to implement some testing around my xpath statements which usually are something like the following:    The test will use a sample xml file The sample will be validated against the schema The test will execute the xpath statement and then check the results are as expected     Walk-through BizTalk uses the XPathNavigator internally behind the xpath function to implement the queries you will usually use using the navigators select or evaluate functions. In the sample (link at bottom) I have a small solution which contains a schema from which I have generated a sample instance. I will then use this instance as the basis for my tests.     In the below diagram you can see the helper class which I've encapsulated my xpath expressions in, and some helper functions which will format the expression in the case of a repeating node which would want to inject an index into the xpath query.             I have then created a test class which has some functions to execute some queries against my sample xml file. An example of this is below.         In the test class I have a couple of helper functions which will execute the xpath expressions in a similar way to BizTalk. You could have a proper helper class to do this if you wanted.         You can see now in the BizTalk expression editor I can use these functions alongside the xpath function.         Conclusion I hope you can see with very little effort you can make your life much easier by testing xpath statements outside of an orchestration rather than using them directly hard coded into the orchestration.     This can also save you lots of pain longer term because your build should break if your schema changes unexpectedly causing these xpath tests to fail where as your tests around the orchestration will be more difficult to troubleshoot and workout the cause of the problem.     Sample Link The sample is available from the following link: http://code.msdn.microsoft.com/testbtsxpathfunction     Other Tools On the subject of using the xpath function, if you don't already use it the below tool is very useful for creating your xpath statements (thanks BizBert) http://www.bizbert.com/bizbert/2007/11/30/XPath+The+Hidden+Language+Of+BizTalk.aspx

• "Win32 exception occurred releasing IUnknown at..." error using Pylons and WMI

  - by Anders

  Hi all, Im using Pylons in combination with WMI module to do some basic system monitoring of a couple of machines, for POSIX based systems everything is simple - for Windows - not so much. Doing a request to the Pylons server to get current CPU, however it's not working well, or atleast with the WMI module. First i simply did (something) this: c = wmi.WMI() for cpu in c.Win32_Processor(): value = cpu.LoadPercentage However, that gave me an error when accessing this module via Pylons (GET http://ip:port/cpu): raise x_wmi_uninitialised_thread ("WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex]") x_wmi_uninitialised_thread: <x_wmi: WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex] (no underlying exception)> Looking at http://timgolden.me.uk/python/wmi/tutorial.html, i wrapped the code accordingly to the example under the topic "CoInitialize & CoUninitialize", which makes the code work, but it keeps throwing "Win32 exception occurred releasing IUnknown at..." And then looking at http://mail.python.org/pipermail/python-win32/2007-August/006237.html and the follow up post, trying to follow that - however pythoncom._GetInterfaceCount() is always 20. Im guessing this is someway related to Pylons spawning worker threads and crap like that, however im kinda lost here, advice would be nice. Thanks in advance, Anders

• 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?

• @font-face problems

  - by codedude

  Right now I'm trying desperately to get @font-face to work in my website. This is the code I am using right now. @font-face { font-family: romeral; src: url(fonts/romeral.otf ) format("opentype"); } And then.... h1 { font-size:2.5em; font-family:romeral; } I am using the font Romeral. Here's a link to it: http://www.smashingmagazine.com/2007/02/06/freefont-of-the-week-romeral/ For some reason it just won't work. It won't render the font on the page. I've tried using other fonts like Ripe, and they work. I've made sure I don't have any spelling errors. What I'm wondering is if there is a restriction that some fonts use to stop people from using their fonts with @font-face. Or maybe I've made an obvious mistake in my code. Thanks in advance.

• Creating a (ClickOnce) setup for VSTO Outlook Add-in

  - by Ward Werbrouck

  So I created an Outlook Add-in and used the click-once setup to deploy it. The setup runs fine when the user is administrator, but otherwise: no go. Running the setup with "run as..." and logging in as admin works, but than the add-in is installed under the admin, not the current user. The addin doesn't show up in outlook. I tried following this guide: http://blogs.msdn.com/mshneer/archive/2008/04/24/deploying-your-vsto-add-in-to-all-users-part-iii.aspx But I get stuck at part I: http://blogs.msdn.com/mshneer/archive/2007/09/04/deploying-your-vsto-add-in-to-all-users-part-i.aspx I follow the examples and start excel as described: Now start Excel application.

• Sharing session state between 2 ASP.NET applications using SQL Server

  - by Dave

  Hi I'm working on a site that has a requirement to share session between a cms application and an online store application on the same domain eg. mydomain.com and store.mydomain.com I've made some progress with it and it works on my local build between localhost/cms and localhost/store Basically I have done what is suggested in this article http://blogs.msdn.com/toddca/archive/2007/01/25/sharing-asp-net-session-state-across-applications.aspx and hacked the TempGetAppID Stored Procedure to return the same application id (1). This appears to work as it creates sessions with ids like 'abv5d2urx1asscfwuzw3wp4500000001', which is what I'd expect. My issue is that when I deploy it to our testing environment, it creates a new session when I navigate between the 2 sites. So when I start a session on the cms site, if I navigate to the store, it creates a new session. These are set up as 2 different websites in IIS7. In the web.config files for both sites, the and elements are both the same and are as follows (minus sensitive information) Has anyone got an ideas why this might not be working? I am sharing Forms Authentication across the 2 sites and that works fine. Any help or ideas would be greatly appreciated! Many thanks Dave

• HttpWebRequest: The request was aborted: The request was canceled.

  - by Emeka

  I've been working on developing a middle man application of sorts, which uploads text to a CMS backend using HTTP post requests for a series of dates (usually 7 at a time). I am using HttpWebRequest to accomplish this. It seems to work fine for the first date, but when it starts the second date I get the System.Net.WebException: The request was aborted: The request was canceled. I've searched around and found the following big clues: http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/0d0afe40-c62a-4089-9d8b-fb4d206434dc http://www.jaxidian.org/update/2007/05/05/8 http://arnosoftwaredev.blogspot.com/2006/09/net-20-httpwebrequestkeepalive-and.html And they haven't been too helpful. I've tried overloading the GetWebReuqest but that doesn't make sense because I don't make any use of that function. Here is my code: http://pastebin.org/115268 I get the error on line 245 after it has run successfully at least once. I'd appreciate any help I can get as this is the last step in a project I've been working on for sometime. This is my first C#/VS project so I'm open to any tips but I would like to focus on getting this problem solved first. THanks!

• Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid

  - by viatropos

  I've been struggling with this for a few days now, haven't pinpointed the problem. I am trying to get OpenID to work in Rails 2.3 and Rails 3, using ruby-openid rack-openid open_id_authentication I am logging in using my viatropos.myopenid.com account, but it consistently returns this error: Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid What could that be from, it's not a very descriptive error... Does it have to do with something ruby-specific, or is this entirely on the OpenID protocol side of things? More specifically, I am using Authlogic and ActiveRecord, so could this be a problem with my User or UserSession models somehow? Or is it more to do with the header or request?

• SQL Compact allow only one WCF Client

  Hi, I write a little Chat Application. To save some infos like Username and Password I store the Data in an SQL-Compact 3.5 SP1 Database.

I googled for this, but no one seems the same error I get :( SOLUTION I used the wrapper in http://csharponphone.blogspot.com/2007/01/keeping-sqlceconnection-open-and-thread.html for threat safty, and now it works :) Client Code: public test() { var newCompositeType = new Client.ServiceReference1.CompositeType(); newCompositeType.StringValue = "Hallo" + DateTime.Now.ToLongTimeString(); newCompositeType.Save = (Console.ReadKey().Key == ConsoleKey.J); ServiceReference1.Service1Client sc = new Client.ServiceReference1.Service1Client(); sc.Open(); Console.WriteLine("Save " + newCompositeType.StringValue); sc.GetDataUsingDataContract(newCompositeType); sc.Close(); } Server Code public CompositeType GetDataUsingDataContract(CompositeType composite) { if (composite.Save) { SqlCeConnection con = new SqlCeConnection(Properties.Settings.Default.Con); con.Open(); var com = con.CreateCommand(); com.CommandText = "SELECT * FROM TEST"; SqlCeResultSet result = com.ExecuteResultSet(ResultSetOptions.Scrollable | ResultSetOptions.Updatable); var rec = result.CreateRecord(); rec["TextField"] = composite.StringValue; result.Insert(rec); result.Close(); result.Dispose(); com.Dispose(); con.Close(); con.Dispose(); } return composite; }

• Difficulties using custom control - RichTextEditor

  - by Chris

  I am working on a school project that uses ASP.NET. I found this TextEditor control ( http://blogs.msdn.com/kirti/archive/2007/11/10/rich-text-editor-is-here.aspx ) that I am trying to include but it isn't working. The error I am getting is: Error Rendering Control - TextEditor. An unhandled exception has occurred. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. I see this error when I go Design part of the editor. I just don't understand this error at all. Also I am a lil bit confused as there is no parameter called index. :( What I have done is reference the binary in my project and then on the page I am trying to use it have registered its namespace and assembly with this line: <%@ Register Assembly="RichTextEditor" Namespace="AjaxControls" TagPrefix="rtt" %> I then go ahead and try to add the control to the page with this line of code: <rtt:richtexteditor ID="TextEditor" Theme="Blue" runat="server" /> Any help would be much appreciated. I haven't done anything like add a custom control before.

• Hg: How to do a rebase like git's rebase

  - by jpswain09

  Hey guys, In Git I can do this: 1. Start working on new feature: $ git co -b newfeature-123 # (a local feature development branch) do a few commits (M, N, O) master A---B---C \ newfeature-123 M---N---O 2. Pull new changes from upstream master: $ git pull (master updated with ff-commits) master A---B---C---D---E---F \ newfeature-123 M---N---O 3. Rebase off master so that my new feature can be developed against the latest upstream changes: (from newfeature-123) $ git rebase master master A---B---C---D---E---F \ newfeature-123 M---N---O I want to know how to do the same thing in Mercurial, and I've scoured the web for an answer, but the best I could find was this: http://www.selenic.com/pipermail/mercurial/2007-June/013393.html That link provides 2 examples: 1. I'll admit that this: (replacing the revisions from the example with those from my own example) hg up -C F hg branch -f newfeature-123 hg transplant -a -b newfeature-123 is not too bad, except that it leaves behind the pre-rebase M-N-O as an unmerged head and creates 3 new commits M',N',O' that represent them branching off the updated mainline. Basically the problem is that I end up with this: master A---B---C---D---E---F \ \ newfeature-123 \ M'---N'---O' \ newfeature-123 M---N---O this is not good because it leaves behind local, unwanted commits that should be dropped. The other option from the same link is hg qimport -r M:O hg qpop -a hg up F hg branch newfeature-123 hg qpush -a hg qdel -r qbase:qtip and this does result in the desired graph: master A---B---C---D---E---F \ newfeature-123 M---N---O but these commands (all 6 of them!) seem so much more complicated than $ git rebase master I want to know if this is the only equivalent in Hg or if there is some other way available that is simple like Git. Thanks!! Jamie

• What framework would allow for the largest coverage of freelance developers in the media/digital mar

  - by optician

  This question is not about which is the best, it is about which makes the most business sense to use as a company's platform of choice for ongoing freelance development. I'm currently trying to decide what framework to move my company in regarding frameworks for web application work. Options are ASP.NET MVC Django CakePHP/Symfony etc.. Struts Pearl on Rails Please feel free to add more to the discussion. I currently work in ASP.NET MVC in my Spare time, and find it incredibly enjoyable to work with. It is my first experince with an MVC framework for the web, so I can't talk on the others. The reason for not pushing this at the company is that I feel that there are not many developers in the Media/Marketing world who would work with this, so it may be hard to extend the team, or at least cost more. I would like to move into learning and pushing Django, partly to learn python, partly to feel a bit cooler (all my geeky friends use Java/Python/c++). Microsoft is the dark side to most company's I work with (Marketing/Media focused). But again I'm worried about developers in this sector. PHP seems like the natural choice, but I'm scared by the sheer amount of possible frameworks, and also that the quality of developer may be lower. I know there are great php developers out there, but how many of them know multiple frameworks? Are they similar enough that anyone decent at php can pick them up? Just put struts in the list as an option, but personally I live with a Java developer, and considering my experience with c#, I'm just not that interested in learning Java (selfish personal geeky reasons) Final option was a joke http://www.bbc.co.uk/blogs/radiolabs/2007/11/perl_on_rails.shtml

• Set up Gitosis, but can't clone

  - by Tim Rupe

  I've set up Gitosis on a remote Ubuntu box which I will refer to as linuxserver as my host in the following commands. I'm also connecting from a Windows box using Cygwin. I followed the instructions according to: http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way I had no problems up until I needed to clone the gitosis-admin repository to my local machine git clone git@linuxserver:gitosis-admin.git When I do this, the command executes, but hangs there displaying nothing until I ctrl-c to get back to a command prompt. No messages are displayed at all. I'm pretty sure I have my ssh keys set up properly, because logging in using "ssh linuxserver" into my regular account works perfectly without asking for a password. Edit: Over the weekend I set up a near identical Ubuntu box at home, and had no problem setting up Gitosis. The only difference was that I was connecting from OSX instead of Cygwin. Edit: I've also discovered that when using the Bash Shell provided with "Git Extensions", I have no problems, so the issue definitely seems to be some kind of Cygwin conflict. Edit: Just an update, but about a month after posting this question, I switched to Mercurial, and found that I prefer it much more than git. Thanks for the suggestions, but I don't plan on going back to git to try any of them out.

• django: cannot import settings, cannot login to admin, cannot change admin password

  - by xpanta

  Hi, It seems that I am completely lost here. Yesterday I noticed that I cannot login to the admin panel (don't use it much, so it's been some weeks since last login). I thought that I might have changed the admin password and now I can't remember it (though I doubt it). I tried django-admin.py changepassword (using django 1.2.1) but it said that 'changepassword' is unknown command (I have all the necessary imports in my settings.py. Admin interface used to work ok). Then I gave a django-admin.py validate. Then the hell begun. django-admin.py validate gave me this error: Error: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined. I then gave a set DJANGO_SETTINGS_MODULE=myproject.settings and then again a django-admin.py validate This is what I get now: Error: Could not import settings 'myproject.settings' (Is it on sys.path? Does it have syntax errors?): No module named myproject.settings and now I am lost. I tried django console and sys.path.append('c:\workspace') or sys.append('c:\workspace\myproject') but still get the same errors. I use windows 7 and my project dir is c:\workspace. I don't use a PYTHONPATH variable (although I tried setting it temporarily to C:\workspace but I still get the same error). I don't use Apache, just the django development server. What am I doing wrong? My web page works fine. I think that the fact that I can't login as admin is related to the previous import error, no? PS: I also tried this: http://coderseye.com/2007/howto-reset-the-admin-password-in-django.html but still I couldn't change admin password for some reason. Although I could create another admin user (with which I couldn't login).

• Setting MinimumSize Attribute for a Control in a TFS WorkItem

  - by Jay Yother

  Tools used: Visual Studio 2008 SP1 Team Explorer Team Foundation Server Power Tools October 2008 Release. Using the Process Editor in Visual Studio, I am attempting to set the MinimumSize attribute for a control in a WorkItem template to make the default size of the input area larger. I am setting the attribute according to this website: http://msmvps.com/blogs/vstsblog/archive/2007/07/07/undocumented-attributes-for-controlling-the-work-item-form-layout.aspx No matter what I set this attribute to it has no affect. I have tried setting the attribute with and without surrounding (). I've tried different capitalization of the attribute but no luck. I have verified that the MinimumSize attribute is being correctly set in the associated xml file. The control (HtmlFieldControl) is currently setup as the second child on a Tab Page. (The first control is also an HtmlFieldControl.) I've tried adding a group to the Tab Page such that the hierarchy is TabPage-Group-Column-Control with no success. I've also tried setting the attribute for the first control with no luck. Any idea what I am doing wrong?

• html - selection range - getting the range + starting node + ending node + distance

  - by sugar

  From my previous question for selecting specific html text, I have gone through this link to understand range in html string. Actually I am confused here very much. My question is as follows. For selecting a specific text on html page. We need to follow this steps. assumed html <h4 id="entry1196"><a href="http://radar.oreilly.com/archives/2007/03/call_for_a_blog_1.html" class="external">Call for a Blogger's Code of Conduct</a></h4> <p>Tim O'Reilly calls for a Blogger Code of Conduct. His proposals are:</p> <ol> <li>Take responsibility not just for your own words, but for the comments you allow on your blog.</li> <li>Label your tolerance level for abusive comments.</li> <li>Consider eliminating anonymous comments.</li> </ol> java script to make selection by range var range = document.createRange(); // create range var startPar = [the p node]; // starting parameter var endLi = [the second li node]; // ending parameter range.setStart(startPar,13); // distance from starting parameter. range.setEnd(endLi,17); // distance from ending parameter range.select(); // this statement will make selection I want to do this in invert way. I mean, assume that selection is done by user on browser (safari). My question is that How can we get starting node ( as we have 'the p node' here ) & ending node ( as we have 'the second li node' here ) and the range as well (as we have 13,17 here) ? Please help me. Thanks in advance for sharing your great knowledge. Sagar

• Warshall Algorithm Logic - Stuck

  I am trying to use this logic to understand what is going on with the adjacency matrix, but i am massivley confused where it says about interspacing for a b c d ..... Could anyone explain what is going on here? Thank you (tagged as java as its the language this was demonstarted to us in, so if anyone posted any code examples they could see it was in that language) http://compprog.wordpress.com/2007/11/15/all-sources-shortest-path-the-floyd-warshall-algorithm/ Here is the code: for (k = 0; k < n; ++k) { for (i = 0; i < n; ++i) for (j = 0; j < n; ++j) /* If i and j are different nodes and if the paths between i and k and between k and j exist, do */ if ((dist[i][k] * dist[k][j] != 0) && (i != j)) /* See if you can't get a shorter path between i and j by interspacing k somewhere along the current path */ if ((dist[i][k] + dist[k][j] < dist[i][j]) || (dist[i][j] == 0)) dist[i][j] = dist[i][k] + dist[k][j];
