  • Visual Studio 2008 not detecting Errors while coding

    - by mouthpiec
    Hi, I just installed VS on another PC, but this time, while I am coding, it is not marking syntax errors while I am coding..... I need to press F6 to get the errors. Normally when for example typing the line below, I get 's' underlined saying that there is a mismatch. Any ideas how I can enable this option? string s = 4;

  • Installing PHP DOM functions on Apache

    - by user352556
    I have just moved my code over to a new server (running on Apache 2.2.3), and PHP's DOM functions are now returning "Fatal error: Class 'DOMDocument' not found". I did some research and it appears that the installation I am now on does not have PHP's DOM functions enabled. I need to enable these functions, so what is the quickest way to go about this? Is it doable from a configuration file or will it require installation of extensions? Thanks!

  • Problem in UITableViewDelegate - RowSelected gives wrong NSIndexPath

    - by vlad259
    I have a UITableViewSource which I have subclassed. I'm overriding GetCell and using my own subclassed cells, like so: public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath) { MarketItem item=_tableItems[indexPath.Section].Items[indexPath.Row]; MarketCell cell=tableView.DequeueReusableCell(_cellIdentifier) as MarketCell; if (cell==null) { cell=new MarketCell(UITableViewCellStyle.Subtitle,_cellIdentifier,item); } // decorate the cell // ... return cell; } This works but when I get events in my UITableViewDelegate, the index path gets me the wrong cell (events like AccessoryButtonTapped, WillSelectRow etc). The Section and Row numbers look correct but when I do a tableView.CellAt(indexPath) I get the wrong cell. (The row and section numbers again look correct.) Things to note: The table is constantly being updated - items arrive in a different thread which are then InvokeOnMainThread'd Although the table is constantly updated, rows and sections are only added - nothing is re-ordered or deleted If I pause the updates when I get a 'WillSelectRow', it doesn't help Most interestingly (but not a shippable solution) if I make a new cell each time rather than doing DequeueReusableCell, it works correctly. I can't help thinking it's a stupid bug of my own making but can't find it. Any help would be most gratefully received!

All the tutorials that I have found seem to style the entire page rather that a particular part of the page. Thanks in advance Decbrad

  • How can I prevent text displacement for some foreign language fonts?

    - by weltraumpirat
    I have a multilingual project (currently 13 languages), which uses many different font variations of "Helvetica Neue", mostly bold, condensed and regular cuts from the LinoType Pro font set ( which includes western european characters) and the same for cyrillic. We will probably add chinese and japanese variations in the future. I have set up the project to use different CSS stylesheets and separately load the fonts for each version, depending on which language the user selects, so I can have different line heights, kerning and/or font sizes to make everything keep the original look, even if the fonts look nothing alike. All of this works well, except for one problem: For some reason, all cyrillic letters seem to be displaced. They appear 2-3 pixels below the correct base line, and actually protrude across the textfield's bottom border, even when the field is set to autosize. When I use textfield.getCharBoundaries(), all values seem to be correct, even though they obviously aren't rendered correctly. To make everything look neat, I could of course manually move all problematic textfields up or down according to language and font size, but I was wondering if there was some way to prevent or at least detect this kind of displacement in order to automatically handle the adjustments - the Flash Player should have some sort of information on how things are rendered, shouldn't it? Have any of you had similar problems? Or better yet: a solution?

  • NHibernateUtil.Initialize and Table where clause (Soft Delete)

    - by Pascal
    We are using NHibernate but sometimes manually load proxies using the NHibernateUtil.Initialize call. We also employ soft delete and have a "where" condition on all our mapping to tables. SQL generated by NHibernate successfully adds the where condition (i.e. DELETED IS NULL) however we notice that NHibernateUtil.Initialize does not observe the constraints of the mapping files. i.e. None of the SQL generated by NHibernateUtil.Initialize observes our DELETED IS NULL condition. Is there something we're missing as we would really like to employ manual loading of some entity collections when the situation demands it. We are using FluentNhibernate for our mapping.

  • Find groups with both validated, unvalidated users

    - by Matchu
    (Not my real MySQL schema, but illustrates what needs done.) Users can belong to many groups, and groups have many users. users: id INT validated TINYINT(1) groups: id INT name VARCHAR(20) groups_users: group_id INT user_id INT I need to find groups that contain both validated and unvalidated users (validated being 1 or 0, respectively), in order to perform a specific manual maintenance task. There are thousands of users, all belong to at least one group, but a group usually only has 2-5 users. This is a live production server, so I could probably craft a query myself, but the last one I tried took a matter of minutes before I killed it. (I'm not one of those brilliant SQL wizards.) I suppose I could take the server down for maintenance, but, if possible, a query that gets this job done in a matter of seconds would be fantastic. Thanks!

  • Entity framework self referencing loop detected

    - by Lyd0n
    I have a strange error. I'm experimenting with a .NET 4.5 Web API, Entity Framework and MS SQL Server. I've already created the database and set up the correct primary and foreign keys and relationships. I've created a .edmx model and imported two tables: Employee and Department. A department can have many employees and this relationship exists. I created a new controller called EmployeeController using the scaffolding options to create an API controller with read/write actions using Entity Framework. In the wizard, selected Employee as the model and the correct entity for the data context. The method that is created looks like this: // GET api/Employee public IEnumerable<Employee> GetEmployees() { var employees = db.Employees.Include(e => e.Department); return employees.AsEnumerable(); } When I call my API via /api/Employee, I get this error: ...The 'ObjectContent`1' type failed to serialize the response body for content type 'application/json; ...System.InvalidOperationException","StackTrace":null,"InnerException":{"Message":"An error has occurred.","ExceptionMessage":"Self referencing loop detected with type 'System.Data.Entity.DynamicProxies.Employee_5D80AD978BC68A1D8BD675852F94E8B550F4CB150ADB8649E8998B7F95422552'. Path '[0].Department.Employees'.","ExceptionType":"Newtonsoft.Json.JsonSerializationException","StackTrace":" ... Why is it self referencing [0].Department.Employees? That doesn't make a whole lot of sense. I would expect this to happen if I had circular referencing in my database but this is a very simple example. What could be going wrong?

  • different thread accessing MemoryStream

    - by Wayne
    There's a bit of code which writes data to a MemoryStream object directly into it's data buffer by calling GetBuffer(). It also uses and updates the Position and SetLength() properties appropriately. This code works purposes 99.9999% of the time. Literally. Only every so many 100,000's of iterations it will barf. The specific problem is that the memory.Position property suddenly returns zero instead of the appropriate value. However, code was added that checks for the 0 and throws an exception which include log of the MemoryStream properties like Position and Length in a separate method. Those return the correct value. Further addition shows that when this rare condition occurs, the memory.Position only has zero inside this particular method. Okay. Obviously, this must be a threading issue. But this code is well locked. However, the nature of this software is that it's organized by "tasks" with a scheduler and so any one of several actual O/S thread may run this code at any give time--but never more than one at a time. So it's my guess that ordinarily it so happens that the same thread keeps getting used for this method and then on a rare occasion a different thread get used. Then due to compiler optimizations, the different thread never gets the correct value. It gets a "stale" value. Ordinarily in a situation like this I would apply a "volatile" keyword to the variable in question. But that (those) variables are inside the MemoryStream object. Does anyone have any other idea? Or does this mean we have to implement our own MemoryStream object? (Just like we end up having to do with practically every collection in .NET?) It's a shame to have such an awesome platform as .NET and have virtually the entire system useless as-is for seriously parallelized applications. If I'm wrong or you have other ideas, please advise. Sincerely, Wayne

  • filling colors on a map - PHP

    - by jeremy
    I am trying to determine how to fill colors onto a map - such as the "Risk" board game map. I've done this before with HTML tables, by pulling an HTML color code from a SQL table and then just using it to fill the cell the color I want it. But for a non-square map, I'm not sure where to look. I have created a very simple two color map - its white with black borders. My desired result is having the 'regions' on the map shaded with a color, based on data in a sql table (just like the "fill" button in Paint). This looks like what I need: http://php.net/manual/en/function.imagefilltoborder.php and now.. how to define the borders... At the moment I have tried nothing, because the question was: how do I have PHP fill parts of an image? I have tried making an image in Paint, and then scratching my head wondering how to fill parts of it. Having stumbled upon a link, let me focus this a bit more: It appears that with imagefilltoborder that I can put an image on my server, perhaps one that looks like a black and white version of the RISK map - black borders and white everything else. Some questions: Is it correct that the 'border' variable should use the color of my border (whatever value black is) so that the code can "see" where the border is? Is it correct that I'll just need to figure out X,Y coords to begin the fill? Does this work if I have 10 different spots to fill on the map? Can I use varying colors from code or pulled from SQL to assign different colors to those 10 spots, and use 10 different X,Y coords to get them all?

  • jQuery API counter++ pause on hover and then resume

    - by Rory
    I need to have this counter pause {stay on current div) while mouseover or hover and resume counter when mouseout. I have tried many ways but still new to jQuery API. <div id="slide_holder"> <div id="slide1" class="hidden"> <img src="images/crane2.jpg" class="fill"> </div> <div id="slide2" class="hidden"> <img src="images/extend_boom.png" class="fill"> </div> <div id="slide3" class="hidden"> <img src="images/Transformers-Bumblebee.jpg" class="fill"> </div> <script> $(function () { var counter = 0, divs = $('#slide1, #slide2, #slide3'); function showDiv () { divs.hide() // hide all divs .filter(function (index) { return index == counter % 3; }) // figure out correct div to show .fadeIn('slow'); // and show it counter++; }; // function to loop through divs and show correct div showDiv(); // show first div setInterval(function () { showDiv(); // show next div }, 3 * 1000); // do this every 10 seconds }); </script>

  • CREATE VIEW called multiple times not creating all views

    - by theninepoundhammer
    Noticing strange behavior in SQL 2005, both Express and Enterprise Edition: In my code I need to loop through a series of values (about five in a row), and for each value, I need to insert the value into a table and dynamically create a new view using that value as part of the where clause and the name of the view. The code runs pretty quickly, but what I'm noticing is that all the values are inserted into the table correctly but only the LAST view is being created. Every time. For example, if the values I'm using are X1, X2, X3, X4, and X5, I'll run the process, open up Mgmt Studio, and see five rows in the table with the correct five values, but only one view named MyView_x5 that has the correct WHERE clause. At first, I had this loop in an SSIS package as part of a larger data flow. When I started noticing this behavior, I created a stored proc that would create the CREATE VIEW statement dynamically after the insert and called EXECUTE to create the view. Same result. Finally, I created some C# code using the Enterprise Library DAAB, and did the insert and CREATE VIEW statements from my DLL. Same result every time. Most recently, I turned on Profiler while running against the Enterprise Edition and was able to verify that the Batch Started and Batch Completed events were being fired off for each instance of the view. However, like I said, only the last view is actually being created. Does anyone have any idea why this might be happening? Or any suggestions about what else to check or profile? I've profiled for error messages, exceptions, etc. but don't see any in my trace file. My express edition is 9.00.1399.06. Not sure about the Enterprise edition but think it is SP2.

  • java - question about thread abortion and deadlock - volatile keyword

    - by Tiyoal
    Hello all, I am having some troubles to understand how I have to stop a running thread. I'll try to explain it by example. Assume the following class: public class MyThread extends Thread { protected volatile boolean running = true; public void run() { while (running) { synchronized (someObject) { while (someObject.someCondition() == false && running) { try { someObject.wait(); } catch (InterruptedException e) { e.printStackTrace(); } } // do something useful with someObject } } } public void halt() { running = false; interrupt(); } } Assume the thread is running and the following statement is evaluated to true: while (someObject.someCondition() == false && running) Then, another thread calls MyThread.halt(). Eventhough this function sets 'running' to false (which is a volatile boolean) and interrupts the thread, the following statement is still executed: someObject.wait(); We have a deadlock. The thread will never be halted. Then I came up with this, but I am not sure if it is correct: public class MyThread extends Thread { protected volatile boolean running = true; public void run() { while (running) { synchronized (someObject) { while (someObject.someCondition() == false && running) { try { someObject.wait(); } catch (InterruptedException e) { e.printStackTrace(); } } // do something useful with someObject } } } public void halt() { running = false; synchronized(someObject) { interrupt(); } } } Is this correct? Is this the most common way to do this? This seems like an obvious question, but I fail to come up with a solution. Thanks a lot for your help.

  • URL routing in an MVC framework - PHP

    - by Walderman
    I'm developing an MVC framework in PHP from scratch; mostly for the learning experience but this could easily end up in a live project. I went through this tutorial as a base and I've expanded from there. Requests are made like this: examplesite.com/controller/action/param1/param2/ and so on... And this is my .htaccess file: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?rt=$1 [L,QSA] So all requests go to index.php and they are routed to the correct controller and action from there. If no controller or action is given, then the default 'index' is assumed for both. I have an index controller with an index action, which is supposed to be the home page of my site. I can access it by going to examplesite.com (since the index part is assumed). It has some images, a link to a stylesheet, and some scripts. They are linked with paths relative to index.php. I thought this would be fine since all request go to index.php and all content is simply included in this page using php. This works if I go to examplesite.com. I will see all of the images and styles, and scripts will run. However, if I go to examplesite.com/index, I am routed to the correct part of the site, but all of the links don't work. Does the browser think I am in a different folder? I would like to be able to use relative paths for all of the content in my site, because otherwise I need to use absolute paths everywhere to make sure things will show up. Is this possible?

  • c++ floating point precision loss: 3015/0.00025298219406977296

    - by SigTerm
    The problem. Microsoft Visual C++ 2005 compiler, 32bit windows xp sp3, amd 64 x2 cpu. Code: double a = 3015.0; double b = 0.00025298219406977296; //*((unsigned __int64*)(&a)) == 0x40a78e0000000000 //*((unsigned __int64*)(&b)) == 0x3f30945640000000 double f = a/b;//3015/0.00025298219406977296; the result of calculation (i.e. "f") is 11917835.000000000 (*((unsigned __int64*)(&f)) == 0x4166bb4160000000) although it should be 11917834.814763514 (i.e. *((unsigned __int64*)(&f)) == 0x4166bb415a128aef). I.e. fractional part is lost. Unfortunately, I need fractional part to be correct. Questions: 1) Why does this happen? 2) How can I fix the problem? Additional info: 0) The result is taken directly from "watch" window (it wasn't printed, and I didn't forget to set printing precision). I also provided hex dump of floating point variable, so I'm absolutely sure about calculation result. 1) The disassembly of f = a/b is: fld qword ptr [a] fdiv qword ptr [b] fstp qword ptr [f] 2) f = 3015/0.00025298219406977296; yields correct result (f == 11917834.814763514 , *((unsigned __int64*)(&f)) == 0x4166bb415a128aef ), but it looks like in this case result is simply calculated during compile-time: fld qword ptr [__real@4166bb415a128aef (828EA0h)] fstp qword ptr [f] So, how can I fix this problem? P.S. I've found a temporary workaround (i need only fractional part of division, so I simply use f = fmod(a/b)/b at the moment), but I still would like to know how to fix this problem properly - double precision is supposed to be 16 decimal digits, so such calculation isn't supposed to cause problems.

  • Most watched videos this week

    - by Jan Hancic
    I have a youtube like web-page where users upload&watch videos. I would like to add a "most watched videos this week" list of videos to my page. But this list should not contain just the videos that ware uploaded in the previous week, but all videos. I'm currently recording views in a column, so I have no information on when a video was watched. So now I'm searching for a solution to how to record this data. The first is the most obvious (and the correct one, as far as I know): have a separate table in which you insert a new line every time you want to record a new view (storing the ID of the video and the timestamp). I'm worried that I would quickly get huge amounts of data in this table, and queries using this table would be extremely slow (we get about 3 million views a month). The second solution isn't as flexible but is more easy on the database. I would add 7 columns to the "videos" table (one for each day of the week): views_monday, views_tuesday , views_wednesday, ... And increment the value in the correct column based on the day it is. And I would reset the current day's column to 0 at midnight. I could then easily get the most watched videos of the week by summing this 7 columns. What do you think, should I bother with the first solution or will the second one suffice for my case? If you have a better solution please share! Oh, I'm using MySQL.

  • Can't detect MIME type when using Zend Zend_File_Transfer_Adapter_Http !

    - by mrblue
    Hi all, I am writing a small script to upload and detect MIME type, using Zend Framework. For the design purpose, I can't use Zend_Form but normal instead. And I simply apply from the manual : $adapter = new Zend_File_Transfer_Adapter_Http(); $files = $adapter-getFileInfo(); $mime = $files-getMimeType(); But the system inform that the funcion getMimeType() does not existed. Then, I tried: $adapter = new Zend_File_Transfer(); $files = $adapter-getFileInfo(); $mime = $files-getMimeType(); This time, it didn't work either. So, how can I get the MIME type ? Thank you so much for your help

  • Platform independent remote file editing

    - by Ressu
    I've been investigating possibilities on editing remote files from a website without having a need to download and upload the files manually while editing. So far I've ruled out WebDAV as a possibility since it is cumbersome to use on any platform (it either requires manual setup or works unreliably). Currently I'm looking in to various Applets, but they mostly target either uploading or downloading, not file editing. What I'm currently looking for is an applet that downloads the document, launches the application that is meant to open the file and then monitors the file for changes and uploads the changed file (either automatically or by prompting the user first). I know that I'm not alone with this scenario, so i'm looking for solutions that others have thought of.
