• HTTP Handlers in Win2008/IIS7

  - by Keith Barrows

  We are migrating our web sites from Win2003/IIS6 to Win2008/IIS7. Our .NET code is in a WAP form with compiled binaries. I do dev work on a Win7/IIS7 box so had to learn early how to set up HTTP Handlers in this newer environment. What I have that has worked fine on my box is: <system.webServer> <handlers> <remove name="WebServiceHandlerFactory-Integrated" /> <remove name="ScriptHandlerFactory" /> <remove name="ScriptHandlerFactoryAppServices" /> <remove name="ScriptResource" /> <add name="RivWorks" path="*.riv" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script" preCondition="classicMode,runtimeVersionv2.0,bitness32" /> <add name="RivWorks2" path="*.riv2" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script" preCondition="classicMode,runtimeVersionv2.0,bitness32" /> <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd" preCondition="integratedMode" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </handlers> All I am getting on the new web site when I try to call into the *.riv handler is: 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable. OK. You see interesting things when writing out these questions. Our server is setup in integrated mode and runs on a x64 system. So, I changed the precondition clause to: preCondition="integratedMode,runtimeVersionv2.0,bitness64" Now I get this instead: 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed. Any ideas of what I should be doing, where I should be looking? TIA

• Is there a way to keep track of the ordering of items in a dictionary?

  - by Corpsekicker

  I have a Dictionary<Guid, ElementViewModel>. (ElementViewModel is our own complex type.) I add items to the dictionary with a stock standard items.Add(Guid.NewGuid, new ElementViewModel() { /*setters go here*/ });, At a later stage I remove some or all of these items. A simplistic view of my ElementViewModel is this: class ElementViewModel { Guid Id { get; set; } string Name { get; set; } int SequenceNo { get; set; } } It may be significant to mention that the SequenceNos are compacted within the collection after adding, in case other operations like moving and copying took place. {1, 5, 6} - {1, 2, 3} A simplistic view of my remove operation is: public void RemoveElementViewModel(IEnumerable<ElementViewModel> elementsToDelete) { foreach (var elementViewModel in elementsToDelete) items.Remove(elementViewModel.Id); CompactSequenceNumbers(); } I will illustrate the problem with an example: I add 3 items to the dictionary: var newGuid = Guid.NewGuid(); items.Add(newGuid, new MineLayoutElementViewModel { Id = newGuid, SequenceNo = 1, Name = "Element 1" }); newGuid = Guid.NewGuid(); items.Add(newGuid, new MineLayoutElementViewModel { Id = newGuid, SequenceNo = 2, Name = "Element 2" }); newGuid = Guid.NewGuid(); items.Add(newGuid, new MineLayoutElementViewModel { Id = newGuid, SequenceNo = 3, Name = "Element 3" }); I remove 2 items RemoveElementViewModel(new List<ElementViewModel> { item2, item3 }); //imagine I had them cached somewhere. Now I want to add 2 other items: newGuid = Guid.NewGuid(); items.Add(newGuid, new MineLayoutElementViewModel { Id = newGuid, SequenceNo = 2, Name = "Element 2, Part 2" }); newGuid = Guid.NewGuid(); items.Add(newGuid, new MineLayoutElementViewModel { Id = newGuid, SequenceNo = 3, Name = "Element 3, Part 2" }); On evaluation of the dictionary at this point, I expected the order of items to be "Element 1", "Element 2, Part 2", "Element 3, Part 2" but it is actually in the following order: "Element 1", "Element 3, Part 2", "Element 2, Part 2" I rely on the order of these items to be a certain way. Why is it not as expected and what can I do about it?

  On XP (user account) when running this shortcut: <Shortcut Id="UninstallStartMenuShortcut" Advertise="no" Name="AppName" Description="Uninstalls AppName" Target="[SystemFolder]msiexec.exe" Arguments="/x [ProductCode]"/> I'm getting an error "You must be an Administrator to remove this application. To remove this application, you can log on as an administrator, or contact your technical support group for assistance." Why this happens instead of asking for elevation with admin password? How can I avoid this stupid error?

• How to create a generic method in C# that's all applicable to many types - ints, strings, doubles et

  - by satyajit

  Let's I have a method to remove duplicates in an integer Array public int[] RemoveDuplicates(int[] elems) { HashSet<int> uniques = new HashSet<int>(); foreach (int item in elems) uniques.Add(item); elems = new int[uniques.Count]; int cnt = 0; foreach (var item in uniques) elems[cnt++] = item; return elems; } How can I make this generic such that now it accepts a string array and remove duplicates in it? How about a double array? I know I am probably mixing things here in between primitive and value types. For your reference the following code won't compile public List<T> RemoveDuplicates(List<T> elems) { HashSet<T> uniques = new HashSet<T>(); foreach (var item in elems) uniques.Add(item); elems = new List<T>(); int cnt = 0; foreach (var item in uniques) elems[cnt++] = item; return elems; } The reason is that all generic types should be closed at run time. Thanks for you comments

• Memory leak when application loads in iPhone

  - by iPhoneDev

  I have a navigation based template, when I run my application using Instruments, the very first memory leak comes under: Leak Object: Malloc 128 bytes Responsible Library: CoreGraphics Responsible Frame: open_handle_to_dylib_path I don't know where this leak is coming from and how remove this. If it's a default leak, then I think I don't need to worry about it. But if it's not then I have to find a way to remove the leak.

Thanks in advance!

• Algorithm to determine indices i..j of array A containing all the elements of another array B

  - by Skylark

  I came across this question on an interview questions thread. Here is the question: Given two integer arrays A [1..n] and B[1..m], find the smallest window in A that contains all elements of B. In other words, find a pair < i , j such that A[i..j] contains B[1..m]. If A doesn't contain all the elements of B, then i,j can be returned as -1. The integers in A need not be in the same order as they are in B. If there are more than one smallest window (different, but have the same size), then its enough to return one of them. Example: A[1,2,5,11,2,6,8,24,101,17,8] and B[5,2,11,8,17]. The algorithm should return i = 2 (index of 5 in A) and j = 9 (index of 17 in A). Now I can think of two variations. Let's suppose that B has duplicates. This variation doesn't consider the number of times each element occurs in B. It just checks for all the unique elements that occur in B and finds the smallest corresponding window in A that satisfies the above problem. For example, if A[1,2,4,5,7] and B[2,2,5], this variation doesn't bother about there being two 2's in B and just checks A for the unique integers in B namely 2 and 5 and hence returns i=1, j=3. This variation accounts for duplicates in B. If there are two 2's in B, then it expects to see at least two 2's in A as well. If not, it returns -1,-1. When you answer, please do let me know which variation you are answering. Pseudocode should do. Please mention space and time complexity if it is tricky to calculate it. Mention if your solution assumes array indices to start at 1 or 0 too. Thanks in advance.

• Which options do I have for Java process communication?

  - by Dmitriy Matveev

  We have a place in a code of such form: void processParam(Object param) { wrapperForComplexNativeObject result = jniCallWhichMayCrash(param); processResult(result); } processParam - method which is called with many different arguments. jniCallWhichMayCrash - a native method which is intended to do some complex processing of it's parameter and to create some complex object. It can crash in some cases. wrapperForComplexNativeObject - wrapper type generated by SWIG processResult - a method written in pure Java which processes it's parameter by creation of several kinds (by the kinds I'm not meaning classes, maybe some like hierarchies) of objects: 1 - Some non-unique objects which are referencing each other (from the same hierarchy), these objects can have duplicates created from the invocations of processParam() method with different parameter values. Since it's costly to keep all the duplicates it's necessary to cache them. 2 - Some unique objects which are referencing each other (from the same hierarchy) and some of the objects of 1st kind. After processParam is executed for each of the arguments from some set the data created in processResult will be processed together. The problem is in fact that jniCallWhichMayCrash method may crash the entire JVM and this will be very bad. The reason of crash may be such that it can happen for one argument value and not for the other. We've decided that it's better to ignore crashes inside of JVM and just skip some chunks of data when such crashes occur. In order to do this we should run processParam function inside of separate process and pass the result somehow (HOW? HOW?! This is a question) to the main process and in case of any crashes we will only lose some part of data (It's ok) without lose of everything else. So for now the main problem is implementation of transport between different processes. Which options do I have? I can think about serialization and transmitting of binary data by the streams, but serialization may be not very fast due to object complexity. Maybe I have some other options of implementing this?

• Codeignitor index.php breaking image paths

However, as soon as I add this code into the .htaccess file: RewriteEngine On RewriteCond $1 !^(index\.php) RewriteRule ^(.+)$ index.php?$1 [L] (to remove the index.php from the URL), I get 404 error, even with the exact same path. How do I remove index.php and still have access to my images?

• Margin 0 and fixed background cause weird border OR what?

  I am currently developing this site: tochat.vn As viewing in Firefox 7.0.1, it has annoying white border at top of the page. I have been trying to remove the border in many ways, but nothing really works. Actually, there are 2 things I noticed, when I removed "margin: 0" on body tag (on reset.css) OR when I removed the "fixed" value of background-attachment of the "body" class (on style.css) the border disappeared. But I can't remove these attributes :( Any suggestion?

  I'm using a get request to get some page data but need to strip the break tags from the finished file. Basically what I'm doing is taking the output of the get request and saving it to a file but it has hundereds of break tags in it I need removed. I'm fine with running a batch or vb script after the file is saved to remove the tags but I'm not sure how on how to do that either. So far the only solutions I have seen is to remove entire lines.

• Deleting document attachments in CouchDb

  - by henrik_lundgren

  In CouchDb's documentation, the described method of deleting document attachments is to send a DELETE call to the attachment's url. However, I have noticed that if you edit the document and remove the attachment stub from the _attachment field, it will not be accessible anymore. If i remove foo.txt from the document below and save to CouchDb it will be gone the next time I access the document: { "_id":"attachment_doc", "_rev":1589456116, "_attachments": { "foo.txt": { "stub":true, "content_type":"text/plain", "length":29 } } } Is the attachment actually deleted on disk or is just the reference to it deleted?
