  • SEO Canonical Issue resolution on iis

    - by kacalapy
    i have a site running on IIS that i have Canonical Issue with. the error is: The page with URL "http://www.site.org/images/join_forum.gif" can also be accessed by using URL "https://www.site.org/images/join_forum.gif".Search engines identify unique pages by using URLs. When a single page can be accessed by using any one of multiple URLs, a search engine assumes that there are multiple unique pages. Use a single URL to reference a page to prevent dilution of page relevance. You can prevent dilution by following a standard URL format. how can i resolve this?

  • Regex replace help

    - by Jeremy
    Using the .NET framework, I'm trying to replace double slash characters in a string with a single slash, but it seems to be removing an extra character and I don't know why. I have a string: http://localhost:4170/RCRSelfRegistration//Default.aspx My regex is: [^(://|:\\\\)](\\\\|//|\\/|/\\) And the return value is: http://localhost:4170/RCRSelfRegistratio/Default.aspx You can see that the n in RCRSelfRegistration has been removed. I am not sure why. /// <summary> /// Match on double slashes (//, \\, /\, \/) but do not match :// or :\\ /// </summary> private const string strMATCH = @"[^(://|:\\\\)](\\\\|//|\\/|/\\)"; /// <summary> /// Replace double slashes with single slash /// </summary> /// <param name="strUrl"></param> /// <returns></returns> public static string GetUrl(string strUrl) { string strNewUrl System.Text.RegularExpressions.Regex rxReplace = new System.Text.RegularExpressions.Regex(strMATCH); strNewUrl = rxReplace.Replace(strUrl, "/"); return strNewUrl; }

  • How to limit / throttle bandwidth with *multiple* connections

    - by Led
    I'm writing an app in C# that downloads concurrently (in different threads) using multiple connections to multiple servers, and I'd like to be able to limit the used bandwidth. For a single connection the solution would be simple; I'd use the solution posted here : http://www.codeproject.com/KB/IP/Bandwidth_throttling.aspx which calculates a sleep-time for the single connection. I'd like to know what the best way is to do this for multiple connections. Using the ThrottledStream posted above and dividing the bandwidth (say 2MB/sec) evenly among the connections isn't right, if I'd have 3 very slow connections and 1 very fast one they'd all be capped to 512kb/sec, so the fast one won't go above 512kb/sec and the other 3 wouldn't even make that. The preferred solution I think is to cap only the fastest connection(s) so the slower connections are used optimally. Does anyone have any experience with this, example code or any advice ?

  • Batch vs SQL statement

    - by AspOnMyNet
    a) A SQL statement is a single SQL command (for example, SELECT * FROM table1 or SET NOCOUNT ON). A batch on the other hand, is a number of SQL statements sent to the server for execution as a whole unit. The statements in the batch are compiled into a single execution plan. Batches are separated by the GO command So the only difference between SQL statement and a Batch is that each SQL statement is sent to server as a separate unit and thus is compiled separately from other SQL statements, while SQL statements in a Batch are compiled together? b) I assume one of major differences between a stored procedure and a Batch is that stored procedures are precompiled while Batches aren’t? thanx

  • Consolidate data from many different databases into one with minimum latency

    - by NTDLS
    I have 12 databases totaling roughly 1.0TB, each on a different physical server running SQL 2005 Enterprise - all with the same exact schema. I need to offload this data into a separate single database so that we can use for other purposes (reporting, web services, ect) with a maximum of 1 hour latency. It should also be noted that these servers are all in the same rack, connected by gigabit connections and that the inserts to the databases are minimal (Avg. 2500 records/hour). The current method is very flakey: The data is currently being replicated (SQL Server Transactional Replication) from each of the 12 servers to a database on another server (yes, 12 different employee tables from 12 different servers into a single employee table on a different server). Every table has a primary key and the rows are unique across all tables (there is a FacilityID in each table). What are my options, these has to be a simple way to do this.

  • WPF RichTextBox with no width set

    - by Mick
    I have the following XAML code: <Window x:Class="RichText_Wrapping.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1"> <Grid> <RichTextBox Height="100" Margin="2" Name="richTextBox1"> <FlowDocument> <Paragraph> This is a RichTextBox - if you don't specify a width, the text appears in a single column </Paragraph> </FlowDocument> </RichTextBox> </Grid> ... If you create this window in XAML, you can see that when you don't specify a width for the window, it wraps the text in a single column, one letter at a time. Is there something I'm missing? If it's a known deficiency in the control, is there any workaround? Thanks, Michael

  • accepts_nested_attributes_for and has_many :through relations.

    - by antiarchitect
    I want to make a simple examing application on RoR 2.3. The problem area is to make an exam_session in a one form with only one submit action. For the exam session there are selected some number of questions from the question pool in random order. For these questions there are selected some number of alternatives (to check is this a single answer question or multi answer question I use the number of correct alternatives: if only 1 - single, 1 - multi. Radiobuttons or checkboxes in form to answer depends on it). I have models: Questions ---< Alternative and ExamSession. I think there must be has_many :through relations between ExamSession and Questions and has_many :through relation between the intermediate table (for example QuestionsExamSession) and Alternative to point what alternatives are answers of the student on this Question. So the questions are: Is this scheme is too complicated and there is a way to do it simple and clear? Is there any way to organize models in such a way to make the form I want to work?

  • Right clicking on QHeaderView inside of QTreeView

    - by taynaron
    I've written a descendant of QTreeView with multiple columns. I want to create a popup menu that appears whe nthe user right-clicks over the column headers. I have tried catching signals from QTreeView for this, but QTreeView doesn't seem to emit signals on the headers. QTreeView.header() does. I therefore believe I must either: 1: connect one of QHeaderView's signals to a popup function - I have been unable to find a signal that is triggered on a single right click - I have tried sectionClicked, sectionHandleDoubleClicked, sectionDoubleClicked, sectionPressed (not surprised the double click functions didn't catch a single right click - but they do catch a double right click) self.header().sectionClicked.connect(self.headerMenu) self.header().sectionHandleDoubleClicked.connect(self.headerMenu) self.header().sectionDoubleClicked.connect(self.headerMenu) self.header().sectionPressed.connect(self.headerMenu) or, 2: write a descendant of QHeaderView with my own MousePressEvent function, and use that for my headers. I have so far been unsuccessful in connecting the new header class to the QTreeView descendant. I keep getting a Segmentation Fault on runtime, with no more explanation. #in DiceView's init, where DiceHeaders is the QHeaderView descendant self.setHeader(DiceHeaders()) Any ideas?

  • How to produce a merged RSS feed (from DokuWiki and Serendipity)

    - by symcbean
    Hi, I've got an application developed on top of DokuWiki. I'd like to provide a 'News' page providing the latest updates from the internal RSS feed, some other feeds maintained in Serendipity and potentially other locations. Although its trivial to attach feed parsers to each one individually, I'd like to aggregate this into a single list (possibly a single RSS feed). Both the DokuWiki and Serendipity servers are not connected to the internet - so I can't use an external service for this - looking for code. Anybody got any ideas? TIA C.

  • Light-weight client/server DB?

    - by OverTheRainbow
    Hello, (This question falls between programming and finding a tool, so I guess I'll ask here in SO since it has more activity than SuperUser.) I like the simplicity of SQLite, but by design, it doesn't support concurrent access. The apps I write don't have heavy needs, so I'd like to avoid heavier solutions like MySQL that are more difficult to deploy (remote customers with usually no computer personnel). Does someone know of a good solution that would offer the following features? Client available for VB.Net applications The server itself doesn't have to be a .Net application. Actually, I'd rather a bare-metal server so that it can run even on embedded Linux hosts with less RAM/CPU than regular PC's Easy install: the client part should either be statically linked inside the client application or be available as a single DLL, and the server should just be a single EXE listening for queries, à la Fossil (http://www.fossil-scm.org) clients can locate the server on the LAN by broadcasting data picked up by the server, so users don't have to write down the IP address and paste it into each client open-source, or moderately priced closed-source Thank you.

  • jQuery live() ... have to click twice to activate links?

    - by neezer
    I have the following bit of code, simply: $(function() { $('a.add-photos-link').live('click', function(e) { $(this).colorbox({ overlayClose: false, onComplete: function() { $('#add_photos').submit(function(e) { // more stuff to do e.preventDefault(); }); } }); e.preventDefault(); }); }); However, this only seems to work after single-clicking on the link TWICE. These links are dynamically added to the page (a.add-photos-link). Why is this happening and what can I do to fix it so it fires after the first single-click?

  • Strategy in exporting to Excel with formatting from ASP.NET?

    - by Jiho Han
    So this is another exporting to Excel question. I have a page that has a table with formatting by stylesheet. When I export the page by setting the ContentType to application/excel and Content-Disposition to attachment, I can export the table to Excel (not CSV). However, it loses all formatting. I think it's because Excel does not load CSS and I guess that's reasonable. So, in a scenario where I have to show the table on the web and also export to Excel, both with similar (even if not exact) formatting, what would be the best approach without using something like NPOI? I am trying to minimize the work and keep the single template if possible. Is it necessary for me to create two separate templates: one with stylesheet, the other with embedded style in the table itself for Excel? Having a single template with conditional formatting inside would be very messy. Any ideas?

  • How to manage the default Java SwingWorker thread pool?

    - by Guy Lancaster
    I've got an application that uses 2 long-running SwingWorker tasks and I've just encountered a couple of Windows computers with updated JVMs that only start one of the them. There are no errors indicated so I have to assume that the default thread pool has only a single thread and therefore the second SwingWorker object is getting queued when I try to execute it. So, (1) how do I check check how many threads are available in the default SwingWorker thread pool, and (2) how do I add threads if I'm going to need more? Anything else that I should know? This apparent single-thread thread-pool situation goes against all of my expectations. I'm setting up a ThreadPoolExecutor but this seems so wrong...

  • ASP.Net MVC Where do you convert from Entities to ViewModels?

    - by Pino
    Title pretty much explains it all, its the last thing I'm trying to work into our project. We are structured with a Service Library which contains a function like so. /// <summary> /// Returns a single category based on the specified ID. /// </summary> public Category GetCategory(int CategoryID) { var RetVal = _session.Single<Category>(x => x.ID == CategoryID); return RetVal; } Now Category is a Entity (We are using Entity Framework) we need to convert that to a CategoryViewModel. Now, how would people structure this? Would you make sure the service function returned a CategoryViewModel? Have the controller pull the data from the service then call another function to covnert to a view model?

  • setIncludesSubentities: in an NSFetchRequest is broken for entities across multiple persistent store

    - by SG
    Prior art which doesn't quite address this: http://stackoverflow.com/questions/1774359/core-data-migration-error-message-model-does-not-contain-configuration-xyz I have narrowed this down to a specific issue. It takes a minute to set up, though; please bear with me. The gist of the issue is that a persistentStoreCoordinator (apparently) cannot preserve the part of an object graph where a managedObject is marked as a subentity of another when they are stored in different files. Here goes... 1) I have 2 xcdatamodel files, each containing a single entity. In runtime, when the managed object model is constructed, I manually define one entity as subentity of another using setSubentities:. This is because defining subentities across multiple files in the editor is not supported yet. I then return the complete model with modelByMergingModels. //Works! [mainEntity setSubentities:canvasEntities]; NSLog(@"confirm %@ is super for %@", [[[canvasEntities lastObject] superentity] name], [[canvasEntities lastObject] name]); //Output: "confirm Note is super for Browser" 2) I have modified the persistentStoreCoordinator method so that it sets a different store for each entity. Technically, it uses configurations, and each entity has one and only one configuration defined. //Also works! for ( NSString *configName in [[HACanvasPluginManager shared].registeredCanvasTypes valueForKey:@"viewControllerClassName"] ) { storeUrl = [NSURL fileURLWithPath:[[self applicationDocumentsDirectory] stringByAppendingPathComponent:[configName stringByAppendingPathExtension:@"sqlite"]]]; //NSLog(@"entities for configuration '%@': %@", configName, [[[self managedObjectModel] entitiesForConfiguration:configName] valueForKey:@"name"]); //Output: "entities for configuration 'HATextCanvasController': (Note)" //Output: "entities for configuration 'HAWebCanvasController': (Browser)" if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:configName URL:storeUrl options:options error:&error]) //etc 3) I have a fetchRequest set for the parent entity, with setIncludesSubentities: and setAffectedStores: just to be sure we get both 1) and 2) covered. When inserting objects of either entity, they both are added to the context and they both are fetched by the fetchedResultsController and displayed in the tableView as expected. // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setEntity:entity]; [fetchRequest setIncludesSubentities:YES]; //NECESSARY to fetch all canvas types [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setFetchBatchSize:20]; // Set the batch size to a suitable number. [fetchRequest setAffectedStores:[[managedObjectContext persistentStoreCoordinator] persistentStores]]; [fetchRequest setReturnsObjectsAsFaults:NO]; Here is where it starts misbehaving: after closing and relaunching the app, ONLY THE PARENT ENTITY is fetched. If I change the entity of the request using setEntity: to the entity for 'Note', all notes are fetched. If I change it to the entity for 'Browser', all the browsers are fetched. Let me reiterate that during the run in which an object is first inserted into the context, it will appear in the list. It is only after save and relaunch that a fetch request fails to traverse the hierarchy. Therefore, I can only conclude that it is the storage of the inheritance that is the problem. Let's recap why: - Both entities can be created, inserted into the context, and viewed, so the model is working - Both entities can be fetched with a single request, so the inheritance is working - I can confirm that the files are being stored separately and objects are going into their appropriate stores, so saving is working - Launching the app with either entity set for the request works, so retrieval from the store is working - This also means that traversing different stores with the request is working - By using a single store instead of multiple, the problem goes away completely, so creating, storing, fetching, viewing etc is working correctly. This leaves only one culprit (to my mind): the inheritance I'm setting with setSubentities: is effective only for objects creating during the session. Either objects/entities are being stored stripped of the inheritance info, or entity inheritance as defined programmatically only applies to new instances, or both. Either of these is unacceptable. Either it's a bug or I am way, way off course. I have been at this every which way for two days; any insight is greatly appreciated. The current workaround - just using a single store - works completely, except it won't be future-proof in the event that I remove one of the models from the app etc. It also boggles the mind because I can't see why you would have all this infrastructure for storing across multiple stores and for setting affected stores in fetch requests if it by core definition (of setSubentities:) doesn't work.

  • Sync a WinForm with DatagridView

    - by Ruben Trancoso
    I have a Form with a DataGridView which DataSource is a BindingSource to a table. This view will have a single row selection and a button to delete, edit the current selected row in a popup Form and a insert button that will use the same Form as well. My question is how can I sync the pop Form with the current row? I tryied to use the RowStateChanged event to get and store the current selected Row to be used in the Form but I coudnt. After the event I get the row that was selected before. Other thing I dont understand yet in C# how to have a single recordSet and know wich is the current record even if its a new being inserted in a way that once in the Form all data being entered will show up at the same time in the DataGridView.

  • How do I create a check constraint?

    - by Zack Peterson
    Please imagine this small database... Diagram Tables Volunteer Event Shift EventVolunteer ========= ===== ===== ============== Id Id Id EventId Name Name EventId VolunteerId Email Location VolunteerId Phone Day Description Comment Description Start End Associations Volunteers may sign up for multiple events. Events may be staffed by multiple volunteers. An event may have multiple shifts. A shift belongs to only a single event. A shift may be staffed by only a single volunteer. A volunteer may staff multiple shifts. Check Constraints Can I create a check constraint to enforce that no shift is staffed by a volunteer that's not signed up for that shift's event? Can I create a check constraint to enforce that two overlapping shifts are never staffed by the same volunteer?

  • Blackberry Player, custom data source

    Hello I must create a custom media player within the application with support for mp3 and wav files. I read in the documentation i cant seek or get the media file duration without a custom datasoruce. I checked the demo in the JDE 4.6 but i have still problems... I cant get the duration, it return much more then the expected so i`m sure i screwed up something while i modified the code to read the mp3 file locally from the filesystem.

  • spring add default value to form:select

    - by Mike
    I'm developing a spring application, now I've added a dropdownlist to one of my jsp pages using: <form:select multiple="single" path="users[y.count-1].X" items="${Y}" itemValue="id" itemLabel="name"/> Now I'd like to add the default value "Nothing selected", however I can't seem to find how to do this. I've tried: <form:select multiple="single" path="users[y.count-1].X" items="${Y}" itemValue="id" itemLabel="name"> <form:option value="Nothing selected" /> </form:select> But "Nothing selected" isn't displayed in my dropdownlist.

  • OpenCV in Python can't scan through pixels

    - by Marco L.
    Hi everyone, I'm stuck with a problem of the python wrapper for OpenCv. I have this function that returns 1 if the number of black pixels is greater than treshold def checkBlackPixels( img, threshold ): width = img.width height = img.height nchannels = img.nChannels step = img.widthStep dimtot = width * height data = img.imageData black = 0 for i in range( 0, height ): for j in range( 0, width ): r = data[i*step + j*nchannels + 0] g = data[i*step + j*nchannels + 1] b = data[i*step + j*nchannels + 2] if r == 0 and g == 0 and b == 0: black = black + 1 if black >= threshold * dimtot: return 1 else: return 0 The loop (scan each pixel of a given image) works good when the input is an RGB image...but if the input is a single channel image I get this error: for j in range( width ): TypeError: Nested sequences should have 2 or 3 dimensions The input single channel image (called 'rg' in the next example) is taken from an RGB image called 'src' processed with cvSplit and then cvAbsDiff cvSplit( src, r, g, b, 'NULL' ) rg = cvCreateImage( cvGetSize(src), src.depth, 1 ) # R - G cvAbsDiff( r, g, rg ) I've also already noticed that the problem comes from the difference image got from cvSplit... Anyone can help me? Thank you

  • Selecting an entire photo album with UIImagePickerController

    - by itai alter
    Hello all, I was wondering if there's a way to select an entire photo album with UIImagePickerController. What I have now is a UIImagePickerController with sourceType of PhotoLibrary. It shows the Albums, and navigates inside an album to select a single image... What I want to do is when the user selects the Album, instead of going inside the album, I want to load all the images to an array so I could do a timed slideshow of them. The delegate (DidFinishPickingImage) lets me run code only after the user has already gone into the album and selected a single image. Is there a way to do it? I couldn't find any information on this. Thanks!

  • Why are Pascal control structures inconsistent?

    - by 70Mike
    Most Pascal control structures make sense to me, like: for ... do {statement}; if (condition) then {statement}; while (condition) do {statement}; where the {statement} is either a single statement, or a begin ... end block. I have a problem with: repeat {statement-list} until (expression); try {statement-list} except {statement-list} end; Wouldn't it be better that repeat and try have the same general structure, accepting only a single statement or a begin ... end block, instead of having a statement-list that's not formally blocked with a begin and an end?

  • horizontally scrollable table column

    - by Alexandru Cucu
    Hello, I would need to build a html table that has a horizontally scrolable column. The scroll should be placed in the column's header. My question first question is: do you know any jquery plug-in that is able to do this? My second question: is this possible using a single table. I've heard that in order to do this you need to use multiple synchronized tables that look like a single one from the user's perspective. Any ideea/advice would be welcomed. Thank you.
