• How to minor updates to Drupal-6 with shared hosting

  - by marty.fried

  I've got Drupal working on a shared host, and I uploaded some modules from my home system successfully, but I've got the message that there is a security update for my version, and I should update immediately. I'm not sure how I'm supposed to do that. It seems like the update is an entire new installation. I originally installed it using the hosting company's installer, Fantastico. Should I simply over-write the existing installation with the new files? Or ignore the message? I realize I shouldn't over-write the sites folder, or anything I've modified. The instructions that come with the download seem to be for a major version upgrade, and are way too much trouble for frequent security updates. Searching Drupal's site shows many other methods, but no indication of anything official. And some were ridiculously error-prone, and not really useful. I don't have shell access to the hosting site, although I can pay extra to get it if I really need to. Or, maybe I can clone the site on my local Linux system, do the update using a script, then upload the whole thing. Does anyone have experience with this situation?

• Qt/MFC Migration Framework tool: properly exiting DLL?

  - by User

  I'm using the Qt/MFC Migration Framework tool following this example: http://doc.qt.nokia.com/solutions/4/qtwinmigrate/winmigrate-qt-dll-example.html The dll I build is loaded by a 3rd party MFC-based application. The 3rd party app basically calls one of my exported DLL functions to startup my plugin and another function to shutdown my application. Currently I'm doing nothing in my shutdown function. When I load my DLL in the 3rd party app the startup function is called and my DLL starts successfully and I can see my message box. However if I shutdown my plugin and then try to start it again I get the following error: Debug Error! Program: <my 3rd party app> Module: 4.7.1 File: global\qglobal.cpp Line: 2262 ASSERT failure in QWidget: "Widgets must be created in the GUI thread.", file kernel\qwidget.cpp line 1233 (Press Retry to debug the application) Abort Retry Ignore This makes me think I'm not doing something to properly shutdown my plugin. What do I need to do to shut it down properly? UPDATE: http://doc.qt.nokia.com/solutions/4/qtwinmigrate/winmigrate-walkthrough.html says: The DLL also has to make sure that it can be loaded together with other Qt based DLLs in the same process (in which case a QApplication object will probably exist already), and that the DLL that creates the QApplication object remains loaded in memory to avoid other DLLs using memory that is no longer available to the process. So I wonder if there is some problem where I need to somehow keep the original DLL loaded no matter what?

• ASP.NET:Paging when deleting rows

  - by Niels Bosma

  I have a datagrid where a row can be deleted (using ajax). I'm have problem with the pager in the following scenario: Lets say my PageSize is 10, I have 101 rows so that's 11 pages with the last page with an single element. Let no assume that I'm on page 10 (PageIndex=9) and delete a row. Then I go to the 11'th page (who's now empty and doesn't really exist). ASP now shows me the EmptyDataTemplate and no pager so I can't go back. My approach (which isn't working) is to detect this scenario and step one page back: public void Bind() { gridMain.DataBind(); } public void SetPage(int page) { gridMain.PageIndex = page; gridMain.DataBind(); } protected void ldsGridMain_Selecting(object sender, LinqDataSourceSelectEventArgs e) { selectArgs = e; e.Result = (new EnquiryListController()).GetEnquiryList(OnBind(this), supplier); } protected void ldsGridMain_Selected(object sender, LinqDataSourceStatusEventArgs e) { totalRows = selectArgs.Arguments.TotalRowCount; //Detect if we need to update the page: if (gridMain.PageIndex > 0 && (gridMain.PageSize * gridMain.PageIndex + 1) > totalRows) SetPage(gridMain.PageIndex - 1); } protected void gridMain_PageIndexChanging(object sender, GridViewPageEventArgs e) { SetPage(e.NewPageIndex); } I can see that SetPage is called with the the right page index, but the databind doesn't seem to called as I still get the EmptyDataTemplate.

• Ignoring build number when referencing dll

  - by brickner

  I have one solution with a .NET 4.0 project (C#) that produces a delayed signed dll, that I dotfuscate and sign. EDIT: This is how I version the dll: [assembly: AssemblyVersion("0.7.0.*")] [assembly: AssemblyFileVersion("0.7.0.0")] I have another solution with a .NET 4.0 project (C++/CLI) that references the signed dll and produces a signed dll (actually, delayed signed and signed in a post build because of a flaw in the C++ build system). The problem is that the reference to the dll contains a specific version number, which includes even the build number (I want to have a build number). Every time I build the referenced dll, I have to change the project settings file (.vcxproj) so it reference the new version dll. Since I work with source control, this is very inconvenient (different computers might have different build numbers since each computer build its own referenced dll - the referenced dll is not in the source control). If I don't change the reference, I get a warning: warning MSB3245: Could not resolve this reference. Could not locate the assembly... And many errors like this: error C3083: 'Foo': the symbol to the left of a '::' must be a type These are resolved once I change the reference. How do I make the reference ignore the build number or even the entire version number?

• Trouble with __VA_ARGS__

  - by Noah Roberts

  C++ preprocessor __VA_ARGS__ number of arguments The accepted answer there doesn't work for me. I've tried with MSVC++ 10 and g++ 3.4.5. I also crunched the example down into something smaller and started trying to get some information printed out to me in the error: template < typename T > struct print; #include <boost/mpl/vector_c.hpp> #define RSEQ_N 10,9,8,7,6,5,4,3,2,1,0 #define ARG_N(_1,_2,_3,_4,_5,_6,_7,_8,_9,_10,N,...) N #define ARG_N_(...) ARG_N(__VA_ARGS__) #define XXX 5,RSEQ_N #include <iostream> int main() { print< boost::mpl::vector_c<int, ARG_N_( XXX ) > > g; // ARG_N doesn't work either. } It appears to me that the argument for ARG_N ends up being 'XXX' instead of 5,RSEQ_N and much less 5,10,...,0. The error output of g++ more specifically says that only one argument is supplied. Having trouble believing that the answer would be proposed and then accepted when it totally fails to work, so what am I doing wrong? Why is XXX being interpreted as the argument and not being expanded? In my own messing around everything works fine until I try to pass off VA_ARGS to a macro containing some names followed by ... like so: #define WTF(X,Y,...) X , Y , __VA_ARGS__ #define WOT(...) WTF(__VA_ARGS__) WOT(52,2,5,2,2) I've tried both with and without () in the various macros that take no input.

• Host Primary Domain from a subfolder

  - by TandemAdam

  I am having a problem making a sub directory act as the public_html for my main domain, and getting a solution that works with that domains sub directories too. My hosting allows me to host multiple sites, which are all working great. I have set up a subfolder under my ~/public_html/ directory called /domains/, where I create a folder for each separate website. e.g. public_html domains websiteone websitetwo websitethree ... This keeps my sites nice and tidy. The only issue was getting my "main domain" to fit into this system. It seems my main domain, is somehow tied to my account (or to Apache, or something), so I can't change the "document root" of this domain. I can define the document roots for any other domains ("Addon Domains") that I add in cPanel no problem. But the main domain is different. I was told to edit the .htaccess file, to redirect the main domain to a subdirectory. This seemed to work great, and my site works fine on it's home/index page. The problem I'm having is that if I try to navigate my browser to say the images folder (just for example) of my main site, like this: www.yourmaindomain.com/images/ then it seems to ignore the redirect and shows the entire server directory in the url, like this: www.yourmaindomain.com/domains/yourmaindomain/images/ It still actually shows the correct "Index of /images" page, and show the list of all my images. Here is an example of my .htaccess file that I am using: RewriteEngine on RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ RewriteCond %{REQUEST_URI} !^/domains/yourmaindomain/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /domains/yourmaindomain/$1 RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ RewriteRule ^(/)?$ domains/yourmaindomain/index.html [L] Does this htaccess file look correct? I just need to make it so my main domain behaves like an addon domain, and it's subdirectories adhere to the redirect rules.

• How to run White + SL4 UATs through TeamCity?

  - by Duncan Bayne

  After experiencing a series of unpleasant issues with TFS, including source code orruption and project management inflexibility, we (meaning the project team of which I'm a part) have decided to move from TFS 2010 to TeamCity + SVN + V1. I've managed to get our MSTest component and unit tests running as part of every build. However, our UATs are failing, and I was hoping for some advice from the TeamCity community as to best practices w.r.t. running web servers and interacting with the desktop. Each of our UAT fixtures starts a web server to host the site, like this: public static void StartWebServer() { var pathToSite = @"C:\projects\myproject\FrontEnd\MyProject.FrontEnd.Web"; var webServer = new Process { StartInfo = new ProcessStartInfo { Arguments = string.Format("/port:9150 /path:\"{0}\"", pathToSite), FileName = @"C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\WebDev.WebServer40.EXE" } }; webServer.Start(); } Needless to say, this doesn't work when running through TeamCity, as the pathToSite value is different each time. I'm hoping there is a way of determining the path into which the the code is checked out prior to building? That would allow me to point the web server at the right place. The other issue is that our UATs use White to drive the Silverlight UI through an instance of Internet Explorer: _browserWindow = InternetExplorer.Launch("http://localhost:9150/index.html#/Home", "Home - Windows Internet Explorer"); _document = _browserWindow.SilverlightDocument; I've ensured that the TeamCity service is granted the ability to interact with the desktop, and I've set the build agent machine up to log in automatically (an open session is a pre-requisite for White to work properly). Is that all I need to do or are there additional steps required?

• Help getting MVVM ViewModel to bind to the View

  - by cw

  Okay guys, I'm new to this model and Silverlight in general. I have the following code (changed object names, so syntax/spelling errors ignore). public class ViewModel { ViewModelSource m_vSource; public ViewModel(IViewModelSource source) { m_vSource= source; m_vSource.ItemArrived += new Action<Item>(m_vSource_ItemArrived); } void m_vSource_ItemArrived(Item obj) { Title = obj.Title; Subitems = obj.items; Description = obj.Description; } public void GetFeed(string serviceUrl) { m_vFeedSource.GetFeed(serviceUrl); } public string Title { get; set; } public IEnumerable<Subitems> Subitems { get; set; } public string Description { get; set; } } Here is the code I have in my page's codebehind. ViewModel m_vViewModel; public MainPage() { InitializeComponent(); m_vViewModel = new ViewModel(new ViewModelSource()); this.Loaded += new RoutedEventHandler(MainPage_Loaded); this.DataContext = m_vViewModel; } void MainPage_Loaded(object sender, RoutedEventArgs e) { m_vViewModel.GetItems("http://www.myserviceurl.com"); } Finally, here is a sample of what my xaml looks like. <!--TitleGrid is the name of the application and page title--> <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="My Super Title" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="{Binding Path=Title}" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> I know I'm missing something, but I'm just not knowledgable enough which is why I'm asking you guys :) Is there anything I'm doing wrong here? Thanks!

• pthread condition variables on Linux, odd behaviour.

  - by janesconference

  Hi. I'm synchronizing reader and writer processes on Linux. I have 0 or more process (the readers) that need to sleep until they are woken up, read a resource, go back to sleep and so on. Please note I don't know how many reader processes are up at any moment. I have one process (the writer) that writes on a resource, wakes up the readers and does its business until another resource is ready (in detail, I developed a no starve reader-writers solution, but that's not important). To implement the sleep / wake up mechanism I use a Posix condition value, pthread_cond_t. The clients call a pthread_cond_wait() on the variable to sleep, while the server does a pthread_cond_broadcast() to wake them all up. As the manual says, I surround these two calls with a lock/unlock of the associated pthread mutex. The condition variable and the mutex are initialized in the server and shared between processes through a shared memory area (because I'm not working with threads, but with separate processes) an I'm sure my kernel / syscall support it (because I checked _POSIX_THREAD_PROCESS_SHARED). What happens is that the first client process sleeps and wakes up perfectly. When I start the second process, it blocks on its pthread_cond_wait() and never wakes up, even if I'm sure (by the logs) that pthread_cond_broadcast() is called. If I kill the first process, and launch another one, it works perfectly. In other words, the condition variable pthread_cond_broadcast() seems to wake up only one process a time. If more than one process wait on the very same shared condition variable, only the first one manages to wake up correctly, while the others just seem to ignore the broadcast. Why this behaviour? If I send a pthread_cond_broadcast(), every waiting process should wake up, not just one (and, however, not always the same one).

• Legitimate uses of the Function constructor

  - by Marcel Korpel

  As repeatedly said, it is considered bad practice to use the Function constructor (also see the ECMAScript Language Specification, 5th edition, § 15.3.2.1): new Function ([arg1[, arg2[, … argN]],] functionBody) (where all arguments are strings containing argument names and the last (or only) string contains the function body). To recapitulate, it is said to be slow, as explained by the Opera team: Each time […] the Function constructor is called on a string representing source code, the script engine must start the machinery that converts the source code to executable code. This is usually expensive for performance – easily a hundred times more expensive than a simple function call, for example. (Mark ‘Tarquin’ Wilton-Jones) Though it's not that bad, according to this post on MDC (I didn't test this myself using the current version of Firefox, though). Crockford adds that [t]he quoting conventions of the language make it very difficult to correctly express a function body as a string. In the string form, early error checking cannot be done. […] And it is wasteful of memory because each function requires its own independent implementation. Another difference is that a function defined by a Function constructor does not inherit any scope other than the global scope (which all functions inherit). (MDC) Apart from this, you have to be attentive to avoid injection of malicious code, when you create a new Function using dynamic contents. Lots of disadvantages and it is intelligible that ECMAScript 5 discourages the use of the Function constructor by throwing an exception when using it in strict mode (§ 13.1). That said, T.J. Crowder says in an answer that [t]here's almost never any need for the similar […] new Function(...), either, again except for some advanced edge cases. So, now I am wondering: what are these “advanced edge cases”? Are there legitimate uses of the Function constructor?

• How do I sign requests reliably for the Last.fm api in C#?

  - by Arda Xi

  I'm trying to implement authorization through Last.fm. I'm submitting my arguments as a Dictionary to make the signing easier. This is the code I'm using to sign my calls: public static string SignCall(Dictionary<string, string> args) { IOrderedEnumerable<KeyValuePair<string, string>> sortedArgs = args.OrderBy(arg => arg.Key); string signature = sortedArgs.Select(pair => pair.Key + pair.Value). Aggregate((first, second) => first + second); return MD5(signature + SecretKey); } I've checked the output in the debugger, it's exactly how it should be, however, I'm still getting WebExceptions every time I try. Here's my code I use to generate the URL in case it'll help: public static string GetSignedURI(Dictionary<string, string> args, bool get) { var stringBuilder = new StringBuilder(); if (get) stringBuilder.Append("http://ws.audioscrobbler.com/2.0/?"); foreach (var kvp in args) stringBuilder.AppendFormat("{0}={1}&", kvp.Key, kvp.Value); stringBuilder.Append("api_sig="+SignCall(args)); return stringBuilder.ToString(); } And sample usage to get a SessionKey: var args = new Dictionary<string, string> { {"method", "auth.getSession"}, {"api_key", ApiKey}, {"token", token} }; string url = GetSignedURI(args, true); EDIT: Oh, and the code references an MD5 function implemented like this: public static string MD5(string toHash) { byte[] textBytes = Encoding.UTF8.GetBytes(toHash); var cryptHandler = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] hash = cryptHandler.ComputeHash(textBytes); return hash.Aggregate("", (current, a) => current + a.ToString("x2")); }

• How can I improve this search usability?

  - by Craig Whitley

  This is the first real programming attempt of mine, and theres some major flaws. It's a learning project, and I'm currently re-writing the entire thing as my php is is really messy. I really want to get an idea on how I can improve the actual usability and accesibility of the site at the same time though - so I know how to implement it correctly. The website is basically a comparison website for gameserver hosting. As I mentioned, its a learning project and I don't actually expect any revenue from it. At the moment theres only test data in it, so in the game input box select either 'Battlefied Bad Company 2' or 'Call of Duty 4: Modern Warfare' and ignore the actual search results. http://www.laglessfrag.com I wasn't really sure how to work the search functionality. Basically when you click a game in the drop down box, it sends an ajax request and finds all the locations available to that specific game in the database. After selecting the country theres another ajax to find all the citys available to the game in that country - which gives me the two unique identifiers I need to create the search results. One major and fundamental flaw is that without javascript enabled, the site ceases to function. I'll overcome that in the next re-write, but without the ajax functionality stopping the user 'going wrong' - how can I implement a search that requires two fields without creating extra steps in new pages after form submissions? I'm also no designer so my whole layout and css is a bit rubbish, but this was mainly a learning project as I'm interested in applications / programming rather than design. It's also slow as its on shared hosting, but if I can get it to work correctly then I'm not impartial to chucking a bit of money at it for faster hosting and maybe a bit of advertising and seeing where it goes (if anywhere!). Any info appreciated.

• C# wrapper for array of three pointers

  - by fergs

  I'm currently working on a C# wrapper to work with Dallmeier Common API light. See previous posting: http://stackoverflow.com/questions/2430089/c-wrapper-and-callbacks I've got pretty much everything 'wrapped' but I'm stuck on wrapping a callback which contains an array of three pointers & an array integers: dlm_setYUVDataCllback int(int SessionHandle, void (*callback) (long IPlayerID, unsigned char** yuvData, int* pitch, int width, int height, int64_t ts, char* extData)) Function Set callback, to receive current YUV image. Arguments SessionHandle: handle to current session. Return PlayerID (see callback). Callback - IPlayerId: id to the Player object - yuvData: array of three pointers to Y, U and V part of image The YUV format used is YUV420 planar (not packed). char *y = yuvData[0]; char *u = yuvData[1]; char *v = yuvData[2]; - pitch: array of integers for pitches for Y, U and V part of image - width: intrinsic width of image. - height - ts : timestamp of current frame - extData: additional data to frame How do I go about wrapping this in c#? Any help is much appreciated.

• asyncronous call doesn't return json

  - by Rebecca

  I am running wamp on an xp box. I am fairly new to web programming, this is for a student project, and have run out of avenues to try to solve this problem. Problem We have client side JavaScript code that uses GDownloadUrl- from the Google api- to wrap xmlHttpRequest calls to a php server side program that is accessing our database. In my callback program, the result of this call is always " ". However, if I use an alert to display the http:// call, with the arguments, and cut and paste that into my browser, the json I expected is displayed. I zipped my dir containing all the files, and tried it out on another team member's computer, and they were able to get the json in the callback function. Note this is exactly the same code and structure I was using, he just unzipped and ran. So now I'm thinking this is something about Firefox or Wamp? Would this be a config problem? I'm running wamp server 2.0, and Firefox 3.5.8. I have no problems with syncronous php, or reading in files asyncronously. Any help would be greatly appreciated. Rebecca

• Possible to rank partial matches in Postgres full text search?

  - by Joe

  I'm trying to calculate a ts_rank for a full-text match where some of the terms in the query may not be in the ts_vector against which it is being matched. I would like the rank to be higher in a match where more words match. Seems pretty simple? Because not all of the terms have to match, I have to | the operands, to give a query such as to_tsquery('one|two|three') (if it was &, all would have to match). The problem is, the rank value seems to be the same no matter how many words match. In other words, it's maxing rather than multiplying the clauses. select ts_rank('one two three'::tsvector, to_tsquery('one')); gives 0.0607927. select ts_rank('one two three'::tsvector, to_tsquery('one|two|three|four')); gives the expected lower value of 0.0455945 because 'four' is not the vector. But select ts_rank('one two three'::tsvector, to_tsquery('one|two')); gives 0.0607927 and likewise select ts_rank('one two three'::tsvector, to_tsquery('one|two|three')); gives 0.0607927 I would like the result of ts_rank to be higher if more terms match. Possible? To counter one possible response: I cannot calculate all possible subsequences of the search query as intersections and then union them all in a query because I am going to be working with large queries. I'm sure there are plenty of arguments against this anyway! Edit: I'm aware of ts_rank_cd but it does not solve the above problem.

• What does the Excel VBA range.Rows property really do?

  - by RBarryYoung

  OK, I am finishing up an add-on project for a legacy Excel-VBA application, and I have once again run up against the conundrum of the mysterious range.Rows(?) and worksheet.Rows properties. Does anyone know what these properties really do and what they are supposed to provide to me? (note: all of this probably applies to the corresponding *.Columns properties also). What I would really like to be able to use it for is to return a range of rows, like this: SET rng = wks.Rows(iStartRow, iEndRow) But I have never been able to get it to do that, even though the Intellisense shows two arguments for it. Instead I have to use one of the two or three other (very kludgy) techniques. The help is very unhelpful (typically so for Office VBA), and googling for "Rows" is not very useful, no matter how many other terms I add to it. The only things that I have been able to use it for are 1) return a single row as a range ( rng.Rows(i) ) and 2) return a count of the rows in a range ( rng.Rows.Count ). Is that it? Is there really nothing else that it's good for? Clarification: I know that it returns a range and that there are other ways to get a range of rows. What I am asking for is specifically what do we get from .Rows() that we do not already get from .Cells() and .Range()? The two things that I know are 1) an easier way to return a range of a single row and 2) a way to count the number of rows in a range. Is there anything else?

• Help with possible Haskell type inference quiz questions

  foldr:: (a -> b -> b) -> b -> [a] -> b map :: (a -> b) -> [a] -> [b] mys :: a -> a (.) :: (a -> b) -> (c -> a) -> c -> b what is inferred type of: a.map mys :: b.mys map :: c.foldr map :: d.foldr map.mys :: I've tried to create mys myself using mys n = n + 2 but the type of that is mys :: Num a => a -> a What's the difference between Num a = a - a and just a - a? Or what does 'Num a =' mean? Is it that mys would only take Num type? So anyways, a) I got [a] - [a] I think because it would just take a list and return it +2'd according to my definition of mys b) (a - b) - [a] - [b] I think because map still needs take both arguments like (*3) and a list then returns [a] which goes to mys and returns [b] c) I'm not sure how to do this 1. d) I'm not sure how to do this 1 either but map.mys means do mys first then map right? Are my answers and thoughts correct? If not, why not? THANKS!

• Reading a Wordpress function description

  - by Casebash

  I want to be able to understand the standard function description that is provided for Wordpress functions. In particular, could someone explain the following example from here: Usage <?php wp_list_categories( $args ); ?> Default Usage <?php $args = array( 'show_option_all' => , 'orderby' => 'name', 'order' => 'ASC', 'show_last_update' => 0, 'style' => 'list', 'show_count' => 0, 'hide_empty' => 1, 'use_desc_for_title' => 1, 'child_of' => 0, 'feed' => , 'feed_type' => , 'feed_image' => , 'exclude' => , 'exclude_tree' => , 'include' => , 'current_category' => 0, 'hierarchical' => true, 'title_li' => __( 'Categories' ), 'number' => NULL, 'echo' => 1, 'depth' => 0 ); ?> I can guess most of it, but in particular I can't guess: What does blank after the comma mean? Empty string? What is the __? How do I call the function? Keyword like python, positional arguments or do I have to pass an array? Is there anything else about Wordpress function descriptions which isn't covered in this example? Thanks, Chris

• jQuery - how to repeat a function within itself to include nested files

  - by brandonjp

  I'm not sure what to call this question, since it involves a variety of things, but we'll start with the first issue... I've been trying to write a simple to use jQuery for includes (similar to php or ssi) on static html sites. Whenever it finds div.jqinclude it gets attr('title') (which is my external html file), then uses load() to include the external html file. Afterwards it changes the class of the div to jqincluded So my main index.html might contain several lines like so: <div class="jqinclude" title="menu.html"></div> However, within menu.html there might be other includes nested. So it needs to make the first level of includes, then perform the same action on the newly included content. So far it works fine, but it's very verbose and only goes a couple levels deep. How would I make the following repeated function to continually loop until no more class="jqinclude" elements are left on the page? I've tried arguments.callee and some other convoluted wacky attempts to no avail. I'm also interested to know if there's another completely different way I should be doing this. $('div.jqinclude').each(function() { // begin repeat here var file = $(this).attr('title'); $(this).load(file, function() { $(this).removeClass('jqinclude').addClass('jqincluded'); $(this).find('div.jqinclude').each(function() { // end repeat here var file = $(this).attr('title'); $(this).load(file, function() { $(this).removeClass('jqinclude').addClass('jqincluded'); $(this).find('div.jqinclude').each(function() { var file = $(this).attr('title'); $(this).load(file, function() { $(this).removeClass('jqinclude').addClass('jqincluded'); }); }); }); }); }); });

• JCo | How to iterate column wise

  - by cedar715

  The data from SAP is returned as a JCo.Table. However, we don't want to display ALL the columns in the VIEW. So, what we have done is, we have created a file called display.xml which has the JCO.Table columns to be displayed. The display.xml is converted to a List and each field is verified if it is present in the display list(see the code below) which is redundant from second row onwards. final Table outputTable = jcoFunction.getTableParameterList(). getTable("OUTPUT_TABLE"); final int numRows = outputTable.getNumRows(); for (int i = 0; i < numRows; i++) { final FieldIterator fields = outputTable.fields(); while (fields.hasNextFields()) { final JCO.Field recordField = fields.nextField(); final String sapFieldName = recordField.getName(); final DisplayFieldDto key = new DisplayFieldDto(sapFieldName); if (displayFields.contains(key)) { System.out.println("recordField.getName() = " + recordField.getName()); final String sapFieldName = (String)recordField.getValue(); } else { // ignore the field. } } } What is the better way to filter the fields in JCo? Can I iterate column wise? Thank you :)

• Trying to insert a row using stored procedured with a parameter binded to an expression.

  - by Arvind Singh

  Environment: asp.net 3.5 (C# and VB) , Ms-sql server 2005 express Tables Table:tableUser ID (primary key) username Table:userSchedule ID (primary key) thecreator (foreign key = tableUser.ID) other fields I have created a procedure that accepts a parameter username and gets the userid and inserts a row in Table:userSchedule Problem: Using stored procedure with datalist control to only fetch data from the database by passing the current username using statement below works fine protected void SqlDataSourceGetUserID_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { e.Command.Parameters["@CurrentUserName"].Value = Context.User.Identity.Name; } But while inserting using DetailsView it shows error Procedure or function OASNewSchedule has too many arguments specified. I did use protected void SqlDataSourceCreateNewSchedule_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { e.Command.Parameters["@CreatedBy"].Value = Context.User.Identity.Name; } DetailsView properties: autogen fields: off, default mode: insert, it shows all the fields that may not be expected by the procedure like ID (primary key) not required in procedure and CreatedBy (user id ) field . So I tried removing the 2 fields from detailsview and shows error Cannot insert the value NULL into column 'CreatedBy', table 'D:\OAS\OAS\APP_DATA\ASPNETDB.MDF.dbo.OASTest'; column does not allow nulls. INSERT fails. The statement has been terminated. For some reason parameters value is not being set. Can anybody bother to understand this and help?

• Error when decoding image C# asp

  - by Wayneio

  I am trying to use MessagingToolkit to decode an image in C#/ASP. I have managed to encode a qr using this package, but when i try to decode, using the code below it comes up with 2 errors (at the bottom of the page) I believe this is because I am not getting the image correctly after uploading, but can someone point out exactly where I have gone wrong. Thanks. protected void CreateCode_OnClick(object sender, EventArgs e) { string path = "C:\\Users\\Wayneio\\Documents\\Visual Studio 2012\\Projects\\BAMSystem\\BAMSystem\\"; if (QRUpload.HasFiles == true) { FileInfo fi = new FileInfo(QRUpload.FileName); string extA = fi.Extension; if (extA == ".jpg" || extA == ".png") { QRCodeDecoder decoder = new QRCodeDecoder(); QRUpload.SaveAs(path + QRUpload.FileName); System.Drawing.Image myImg = System.Drawing.Image.FromFile(path + QRUpload.FileName); decoder.Decode(myImg); } else { error.Text = "You have uploaded a " + extA + " file. Please upload either a PNG or a JPG"; } } else { error.Text = "You have not uploaded an image."; } } Error1: Error 2 Argument 1: cannot convert from 'System.Drawing.Image' to 'MessagingToolkit.QRCode.Codec.Data.QRCodeImage' c:\users\wayneio\documents\visual studio 2012\Projects\BAMSystem\BAMSystem\default.aspx.cs 38 35 BAMSystem Error2: Error 1 The best overloaded method match for 'MessagingToolkit.QRCode.Codec.QRCodeDecoder.Decode(MessagingToolkit.QRCode.Codec.Data.QRCodeImage)' has some invalid arguments c:\users\wayneio\documents\visual studio 2012\Projects\BAMSystem\BAMSystem\default.aspx.cs 38 20 BAMSystem P.S if anyone has documentation on this MessagingToolkit QR package, it would be useful
