  • Merging two arrays in PHP

    - by Industrial
    Hi everyone, I am trying to create a new array from two current arrays. Tried array_merge, but it will not give me what I want. $array1 is a list of keys that I pass to a function. $array2 holds the results from that function, but doesn't contain any non-available resuls for keys. So, I want to make sure that all requested keys comes out with 'null':ed values, as according to the shown $result array. It goes a little something like this: $array1 = array('item1', 'item2', 'item3', 'item4'); $array2 = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3' ); Here's the result I want: $result = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3', 'item4' => '' ); It can be done this way, but I don't think that it's a good solution - I really don't like to take the easy way out and suppress PHP errors by adding @:s in the code. This sample would obviously throw errors since 'item4' is not in $array2, based on the example. foreach ($keys as $k => $v){ @$array[$v] = $items[$v]; } So, what's the fastest (performance-wise) way to accomplish the same result?

  • How do I access a <form> that is not the master page <form>?

    - by VBCSharp
    Winforms developer converting to web developer. I know the part about the Master Page having the tag, what is not clear is if I can or can not have another in one of my content pages. I have been seeing both answers doing searches. I see yes you can if only one has runat=server. The thing is I have a that contains several radio buttons on a web page that has a master page. I have a .js file that has a function if I send the name into it, it will loop thru the controls in the form to see which one is selected and return the desired date horizon(MTD, QTD, YTD, etc.). When I run this on a non master page web page it works fine. However, when I run on a web page that has a master page I can't seem to get to the element. I tried getElementByID, I tried looping through the page elements, etc. Maybe I am going about this incorrectly and I hope someone can straighten me out. Here is the code from my .js file that may help explain what I am trying to do a little better. var frmDateRanges = document.getElementById(formFieldName); var chosen; var len = frmDateRanges.DateRanges.length; for(i=0;i<len;i++) { if(frmDateRanges.DateRanges[i].checked) { chosen = frmDateRanges.DateRanges[i].value; } } where formFieldName is an arguement that is passed into the function and DateRanges is the name value given to the radio buttons. In the button I call this function I have: onclick ="FunctionCall('frmDateRanges')" FunctionCall is just for description purposes, 'frmDateRanges' is the name and id given to the form action="" Thanks for the help as I am stumped at this point. If there is a better way to do this please let me know that as well.

  • How can I write simulations in Erlang?

    - by rick
    Hi guys, I want to do some numerical stuff in Erlang like this: You've got an array with the following values: [2,3,4] In each iteration, you calculate 0.1 * [n-1] + 0.7 *[n] + 0.2 * [n+1] This becomes the new [n]. If n == 0 then [n-1] = 0. If [n] == length of array then [n] = 0. So I try an example: [2,3,4] calculations: 0.1 * 0 + 0.7 * 2 + 0.2 * 3 = 2 0.1 * 2 + 0.7 * 3 + 0.2 * 4 = 3.1 0.1 * 3 + 0.7 * 4 + 0.2 * 0 = 3.1 So [2,3,4] becomes to [2, 3.1, 3.1] after one iteration. I know how to write this in a non-functional language like C. But I have difficulties to imagine, how this could be done in Erlang. I found some tutorials on how you read a file to a list. So this is not the problem. How can I spawn different Erlang processes that each process has one element of the list? How can I do calculations by communicating with 'the neighbors', so that the neighbors know where their neigbors are generically, without specifying each? How can I collect the data into a list? Eventually, is it possible to solve that problem in Erlang at all? Thanks for your help.

  • Need advice - Developing a flexible documentation system, heavily focused on localization

    - by inkedmn
    I've been charged with building a documentation system/platform. Here's a short list of the major requirements: Easily localized : This will need to support a dozen or so languages out of the gate. (the ability for non-technical personnel to add/update translations would be a big plus, though not 100% required) Flexibility in output formats : At the bare minimum, I need to output the documents (either as a whole or in selected chunks) as PDF and HTML. Bonus points for native formats like Windows Help Files. Managed and deployed via an intuitive user interface (web, ideally). I'm wondering if you folks know of any systems out there that support this type of thing already? I'm not averse to writing this from scratch, but I'd rather not reinvent the wheel if I can help it. The two major candidates I've come across thus far are DocBook and reST. The former seems to have garnered a reputation for, well, sucking. I'm unfamiliar with either, but I'm told that reST would get me a good portion of the way there. Any other suggestions? Would I be better off building this from scratch?

  • PropertyPlaceholderConfigurer works from Maven command line, but not from Eclipse?

    - by HDave
    I have Eclipse configured to use an external maven instance. Nonetheless I have an integration test that runs fine from the command line, but fails from within Eclipse. The error is a class Spring application context bean error: Cannot convert value of type [java.lang.String] to required type The culprit it a bean that sets property values using a PropertyPlaceholderConfigurer. <!-- property settings for non-JNDI database connections --> <bean id="placeholderConfigUuid" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" /> <property name="location" value="classpath:database.properties" /> <property name="placeholderPrefix" value="$DS{" /> </bean> I know which bean is failing because it appears in the stack trace and because when I replace the $DS{hibernate.dialect} with a static value it works. I have two questions: 1) Since M2Eclipse is using the same Maven setup as the command line, why does one work and the other fail? 2) How to fix this? I really like the ability to run a single jUnit test from within Eclipse on demand.

  • Detect that the onscreen keyboard has been displayed on Windows Phone 7

    - by David_001
    Simple question: How do I detect that the onscreen keyboard has been displayed on windows mobile 7? Is there an event I can add a listener to? It takes up about half the screen and I want to scroll the view up when it gets displayed... EDIT: A comment below indicates more clearly what I'm trying to do: I have a textbox input, and as the user types into it an autocomplete dropdown appears below it (like google suggest). By default, the active control (the textbox) scrolls into view when focussed, and the onscreen keyboard is directly below it. The onscreen keyboard appears in front of my autocomplete dropdown - what I want to do is make the screen scroll a little further up, so there's some room for my dropdown to be shown. The windows phone UI design guidelines say: "When the keyboard is deployed, the application should scroll to ensure the active edit control and the caret are in view". This happens fine, it's just the non-active dropdown gets hidden behind the onscreen keyboard. The guidelines also say that an application can choose to show the onscreen keyboard, and can also choose to close it. At the moment i'm stuck, and I don't think (based on my research and the replies to this question) that it's possible to detect that the onscreen keyboard has been displayed. I'm moving my investigation to see if it's possible to determine the "visible area" of the page (width & height in pixels for example), and combine this with an onfocus for the textbox... not sure if this will prove fruitful though.

  • java.lang.NoClassDefFoundError thrown with my own packages in Android 1.5

    - by TiGer
    Hi, I have developed an application which has several packages within it's project... A class in one of those packages is called right away in the first line of code, which throws the dreaded java.lang.NoClassDefFoundError error... I don't get it, the package simply is within the project, and it works fine on my Android 1.6 device, but won't work with my 1.5 device... I do have to say that the project was originally set for 1.6, but then I changed the within the manifest from 4 to 3... Is that bad practice ? Or maybe it has nothing to do with the platform version ? Also I do get these lines as wel from the DDMS : 05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: unable to resolve static field 2 (MANUFACTURER) in Landroid/os/Build; 05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: rejecting opcode 0x62 at 0x0034 05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: rejected Lmobilaria/android/managementModule/Management;.getDeviceSpecifics ()V 05-04 17:24:59.921: WARN/dalvikvm(2041): Verifier rejected class Lmobilaria/android/managementModule/Management; Thats the ManagementModule which also tries to retrieve several info-fields of the device itself... Again, this works just fine on the 1.6 device, even though thats a development device whilst my 1.5 device is a non-development device...

  • List all foreign key constraints that refer to a particular column in a specific table

    - by Sid
    I would like to see a list of all the tables and columns that refer (either directly or indirectly) a specific column in the 'main' table via a foreign key constraint that has the ON DELETE=CASCADE setting missing. The tricky part is that there would be an indirect relationships buried across up to 5 levels deep. (example: ... great-grandchild- FK3 = grandchild = FK2 = child = FK1 = main table). We need to dig up the leaf tables-columns, not just the very 1st level. The 'good' part about this is that execution speed isn't of concern, it'll be run on a backup copy of the production db to fix any relational issues for the future. I did SELECT * FROM sys.foreign_keys but that gives me the name of the constraint - not the names of the child-parent tables and the columns in the relationship (the juicy bits). Plus the previous designer used short, non-descriptive/random names for the FK constraints, unlike our practice below The way we're adding constraints into SQL Server: ALTER TABLE [dbo].[UserEmailPrefs] WITH CHECK ADD CONSTRAINT [FK_UserEmailPrefs_UserMasterTable_UserId] FOREIGN KEY([UserId]) REFERENCES [dbo].[UserMasterTable] ([UserId]) ON DELETE CASCADE GO ALTER TABLE [dbo].[UserEmailPrefs] CHECK CONSTRAINT [FK_UserEmailPrefs_UserMasterTable_UserId] GO The comments in this SO question inpire this question.

  • Wordpress jQuery Post Attachment Image Gallery?

    - by LearnWebCode
    Hi everyone, Curious if any of you have a good solution for the following situation... because I've never thought of anything myself and usually have to resort to custom fields like "post-image-1" through "post-image-10" and manually paste the file name of a jpg in. Which is a horrible solution and only works for tech savvy posters. Basically I want non-tech savvy users to be able to upload / attach (but not insert into the actual post content) multiple images to a post, which will be turned into a makeshift gallery. Then I want to output these attachments in a list down the page after the post, using basic jQuery lightbox gallery functionality. It doesn't have to be through attachments, it could be a stand alone plugin, as long as it offers customizable markup. Basically any solution that would achieve the same thing would be incredible. Has anyone done this before? Am I missing something terribly obvious? I don't even know what exactly to call this, so I haven't had much luck with my Google research so far :( Thanks!

  • Getting the type of an array of T, without specifying T - Type.GetType("T[]")

    - by Merlyn Morgan-Graham
    I am trying to create a type that refers to an array of a generic type, without specifying the generic type. That is, I would like to do the equivalent of Type.GetType("T[]"). I already know how to do this with a non-array type. E.g. Type.GetType("System.Collections.Generic.IEnumerable`1") // or typeof(IEnumerable<>) Here's some sample code that reproduces the problem. using System; using System.Collections.Generic; public class Program { public static void SomeFunc<T>(IEnumerable<T> collection) { } public static void SomeArrayFunc<T>(T[] collection) { } static void Main(string[] args) { Action<Type> printType = t => Console.WriteLine(t != null ? t.ToString() : "(null)"); Action<string> printFirstParameterType = methodName => printType( typeof(Program).GetMethod(methodName).GetParameters()[0].ParameterType ); printFirstParameterType("SomeFunc"); printFirstParameterType("SomeArrayFunc"); var iEnumerableT = Type.GetType("System.Collections.Generic.IEnumerable`1"); printType(iEnumerableT); var iEnumerableTFromTypeof = typeof(IEnumerable<>); printType(iEnumerableTFromTypeof); var arrayOfT = Type.GetType("T[]"); printType(arrayOfT); // Prints "(null)" // ... not even sure where to start for typeof(T[]) } } The output is: System.Collections.Generic.IEnumerable`1[T] T[] System.Collections.Generic.IEnumerable`1[T] System.Collections.Generic.IEnumerable`1[T] (null) I'd like to correct that last "(null)". This will be used to get an overload of a function via reflections by specifying the method signature: var someMethod = someType.GetMethod("MethodName", new[] { typeOfArrayOfT }); // ... call someMethod.MakeGenericMethod some time later I've already gotten my code mostly working by filtering the result of GetMethods(), so this is more of an exercise in knowledge and understanding.

  • Localization of DisplayNameAttribute

    - by PowerKiKi
    Hi, I am looking for a way to localize properties names displayed in a PropertyGrid. The property's name may be "overriden" using the DisplayNameAttribute attribute. Unfortunately attributes can not have non constant expressions. So I can not use strongly typed resources such as: class Foo { [DisplayAttribute(Resources.MyPropertyNameLocalized)] // do not compile string MyProperty {get; set;} } I had a look around and found some suggestion to inherit from DisplayNameAttribute to be able to use resource. I would end up up with code like: class Foo { [MyLocalizedDisplayAttribute("MyPropertyNameLocalized")] // not strongly typed string MyProperty {get; set;} } However I lose strongly typed resource benefits which is definitely not a good thing. Then I came across DisplayNameResourceAttribute which may be what I'm looking for. But it's supposed to be in Microsoft.VisualStudio.Modeling.Design namespace and I can't find what reference I am supposed to add for this namespace. Anybody know if there's a easier way to achieve DisplayName localization in a good way ? or if there is as way to use what Microsoft seems to be using for Visual Studio ?

  • HTTP 401.3 when PUT, DELETE to ADO.NET Data Service (.svc)

    - by Nate
    I have an ADO.NET Data Service (we'll call it service.svc). When I deploy it to an IIS 6 site with Integrated Windows Authentication turned on, all requests (GET, POST, PUT, and DELETE) work fine for me, because I am an administrator on the box. However, when a non-admin user hits the service, only GET and POST requests work. When they try a PUT or DELETE request, they get an HTTP 401.3 "Access is Denied" error: "Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the web server's administrator to give you access to '...\service.svc'." If I give the "Authenticated Users" local group write access to the .svc file, everything works as it should, but I really don't want to do this (and don't think I should have to do this to get this to work). In fact, I'm confused as to why changing the file permissions would affect this at all, but it definitely seems to be the problem. I've found a couple of different suggestions to fix somewhat similar problems in the Microsoft forums (Here, and I would post more links, but am being told that new users can only post one link in a post), but none of the solutions help. Any help is much appreciated. I am certainly no IIS expert, and this one has got me stumped.

  • Recreating http request with cURL incl. files

    - by Toby
    I consistently get the error 'failed creating formpost data' from the below code, the same thing works perfectly on my local testing server, but on my shared host it throws the error. The sample part is just to simulate building the array with both files and non-file data. Essentially all I'm trying to do here is redirect the same http request to another server, but I'm running into so many troubles. $count=count($_FILES['photographs']['tmp_name']); $file_posts=array('samplesample' => 'ladeda'); for($i=0;$i<$count;$i++) { if(!empty($_FILES['photographs']['name'][$i])) { $fn = genRandomString(); $file_posts[$fn] = "@".$_FILES['photographs']['tmp_name'][$i]; } } $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,"http://myurl/wp-content/plugins/autol/rec.php"); curl_setopt($ch,CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"); curl_setopt($ch,CURLOPT_HEADER,TRUE); curl_setopt($ch,CURLOPT_POST,TRUE); curl_setopt($ch,CURLOPT_POSTFIELDS,$file_posts); curl_exec($ch); print curl_error($ch); curl_close($ch);

  • Laravel4: Checking many-to-many relationship attribute even when it does not exist

    - by Simo A.
    This is my first time with Laravel and also Stackoverflow... I am developing a simple course management system. The main objects are User and Course, with a many-to-many relationship between them. The pivot table has an additional attribute, participant_role, which defines whether the user is a student or an instructor within that particular course. class Course extends Eloquent { public function users() { return $this->belongsToMany('User')->withPivot('participant_role')->withTimestamps(); } } However, there is an additional role, system admin, which can be defined on the User object. And this brings me mucho headache. In my blade view I have the following: @if ($course->pivot->participant_role == 'instructor') { // do something here... } This works fine when the user has been assigned to that particular $course and there is an entry for this user-course combination in the pivot table. However, the problem is the system administrator, who also should be able to access course details. The if-clause above gives Trying to get property of non-object error, apparently because there is no entry in the pivot table for system administrator (as the role is defined within the User object). I could probably solve the problem by using some off-the-shelf bundle for handling role-based permissions. Or I could (but don't want to) do something like this with two internal if-clauses: if (!empty($course->pivot)) { if ($course->pivot->participant_role == 'instructor') { // do something... } } Other options (suggested in partially similar entries in Stackoverflow) would include 1) reading all the pivot table entries to an array, and use in_array to check if a role exists, or even 2) SQL left join to do this on database level. However, ultimately I am looking for a compact one-line solution? Can I do anything similar to this, which unfortunately does not seem to work? if (! empty ($course->pivot->participant_role == 'instructor') ) { // do something... } The shorter the answer, the better :-). Thanks a lot!

  • Javascript not reading value from hidden textBox - JQuery C#

    - by Paul van Valkenburgh
    I'm a non-specialist with JavaScript / JQuery and I'm having trouble figuring out why my script doesn't work. When my C# page loads, I have a hidden textBox txtHiddenKeywordArray which gets dynamically filled with comma separated values like... horse, buggy, track I'm trying to use the highlight functionality in jquery.highlight-3.js where I have a label text field that will contain and highlight the words in the keywords list. I'm using the script <script language="javascript" type="text/javascript"> var myString = document.getElementById('<%=txtHiddenKeywordArray.ClientID%>').val() myArray = myString.split(" "); $(document).ready(function () { for (i = 0; i < myArray.length; i++) $("p").highlight(myArray[i]) }); </script> Here is the textBox declaration : <asp:TextBox ID="txtHiddenKeywordArray" ClientIDMode="Static" runat="server" Visible="false"></asp:TextBox> It worked great when I hard coded the values of var myString. I've tried researching it and keep seeing the same example of the way I have it done. The page does use a MasterPage. Could this affect it? Any idea how I can get the script to see the values from the textbox? Do I need a RegisterStartUpScript or something? Thanks for any help you can provide.

  • Jquery - removing an image before the client browser attempts to download it

    - by ajbrun
    Hi there, I wonder if anyone could help me with a problem I've been having. I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously takes some processing time, which therefore impacts pages load times. I'm fine with this, but I only want to show the image once it's fully loaded, and have a loading gif in its place until that time. I'm using jquery to do this. The problem I'm having is making the page functional whether the client has javascript enabled or not. If JS is not enabled, I want standard img tags to be outputted, otherwise the images are removed and replaced with a loading gif until they have been fully loaded. The link below shows a simple non-javascript unfriendly example of a what I want to do (try turning JS off): http://jqueryfordesigners.com/demo/image-load-demo.php I've been testing the basics using the code below. The attr() function will be replaced with something like remove(). This is just a test to make something happen to the image before the browser tries to load it. $(document).ready(function() { $( "#Thumbnails .thumbnail img" ).attr('src', '#'); }); In IE, this works correctly - the image source is replaced with "#" BEFORE the client browser gets a chance to start downloading the image. In firefox however, it downloads the image, and THEN changes the source. It seems to me that firefox is loading the jquery onready event later than it should. As far as I know, this should be executed before the standard onload event and before anything has started loading. If it helps, I'm testing it with a good number of images on screen (81). Am I doing something wrong?

  • Best way to implement some type of ITaggable interface

    - by Jack
    I've got a program I'm creating that reports on another certain programs backup xml files. I've gotten to the point where I need to implement some type of ITaggable interface - but am unsure how to go about it code wise. My idea is that each item (BackupClient, BackupVersion, and BackupFile) should implement an ITaggable interface for highlighting old, out of date, or non-existent files in their HTML or Excel report. The user will be able to specify tags in the settings. My question is this, how can a user dynamically specify a "tag" such as File Date 3 days old? - Background Color = Red. Actually I guess my question is more, how can I, the programmer, implement this dynamically? I was thinking Expression trees, but am unsure this is the way to go as I havn't studied them much. I know my ITaggable interface would have methods such as AddTag(T tag), RemoveTag(T tag), but what exactly specifies the criteria for the tag to be added? I realize this may be subjective, and can be marked as wiki if need be, but I truly am stuck. Any input would be greatly helpful!

  • Mercurial: Class library that will exist for both .NET 3.5 and 4.0?

    - by Lasse V. Karlsen
    I have a rather big class library written in .NET 3.5 that I'd like to upgrade to make available for .NET 4.0 as well. In that process, I will rip out a lot of old junk, and rewrite some code to better take advantage of the new classes and support in .NET 4.0 (like TPL.) The class libraries will thus diverge, but still be similar enough that some bug-fixes can be done to both in the same manner. How should I best organize this class library in Mercurial? I'm using Kiln (fogbugz) if that matters. I'm thinking: Named branches in one repository, can then transplant any bugfixes from one to the other Unnamed branches in one repository, can also transplant, but I think this will look messy Separate repositories, will have to reimplement the bugfixes (or use a non-mercurial-integraded compare tool to help me) What would you do? (any other alternatives that I haven't though of is welcome as well.) Note that the class libraries will diverge pretty heavily in areas, I have some remnants of old collection-type code that does something similar to Linq that I will remove, and some code that uses it that I will rewrite to use the Linq-methods instead. As such, just copying the project files and using #if NET40..#endif sections is not going to work out. Also, the 3.5 version of the class library will not be getting many new features, mostly just critical bug-fixes, so keeping both versions equally "alive" isn't really necessary. Thus, separate copies of all the files are good enough.

  • IS operator behaving a bit strangely

    - by flockofcode
    1) According to my book, IS operator can check whether expression E (E is type) can be converted to the target type only if E is either a reference conversion, boxing or unboxing. Since in the following example IS doesn’t check for either of the three types of conversion, the code shouldn’t work, but it does: int i=100; if (i is long) //returns true, indicating that conversion is possible l = i; 2) a) B b; A a = new A(); if (a is B) b = (B)a; int i = b.l; class A { public int l = 100; } class B:A { } The above code always causes compile time error “Use of unassigned variable”. If condition a is B evaluates to false, then b won’t be assigned a value, but if condition is true, then it will. And thus by allowing such a code compiler would have no way of knowing whether the usage of b in code following the if statement is valid or not ( due to not knowing whether a is b evaluates to true or false) , but why should it know that? Intsead why couldn’t runtime handle this? b) But if instead we’re dealing with non reference types, then compiler doesn’t complain, even though the code is identical.Why? int i = 100; long l; if (i is long) l = i; thank you

  • Why use Entity Framework over Linq2SQL if...

    - by Refracted Paladin
    To be clear, I am not asking for a side by side comparision which has already been asked Ad Nauseum here on SO. I am also Not asking if Linq2Sql is dead as I don't care. What I am asking is this.... I am building internal apps only for a non-profit organization. I am the only developer on staff. We ALWAYS use SQL Server as our Database backend. I design and build the Databases as well. I have used L2S successfully a couple of times already. Taking all this into consideration can someone offer me a compelling reason that I should use EF instead of L2S? I was at Code Camp this weekend and after an hour long demonstration on EF, all of which I could have done in L2S, I asked this same question. The speakers answer was, "L2S is dead..." Very well then! NOT! (see here) I understand EF is what MS WANTS us to use in the future(see here) and that it offers many more customization options. What I can't figure out is if any of that should, or does, matter for me in this environment. One particular issue we have here is that I inherited the Core App which was built on 4 different SQL Data bases. L2S has great difficulty with this but when I asked the aforementioned speaker if EF would help me in this regard he said "No!"

  • Nested bind expressions

    - by user328543
    This is a followup question to my previous question. #include <functional> int foo(void) {return 2;} class bar { public: int operator() (void) {return 3;}; int something(int a) {return a;}; }; template <class C> auto func(C&& c) -> decltype(c()) { return c(); } template <class C> int doit(C&& c) { return c();} template <class C> void func_wrapper(C&& c) { func( std::bind(doit<C>, std::forward<C>(c)) ); } int main(int argc, char* argv[]) { // call with a function pointer func(foo); func_wrapper(foo); // error // call with a member function bar b; func(b); func_wrapper(b); // call with a bind expression func(std::bind(&bar::something, b, 42)); func_wrapper(std::bind(&bar::something, b, 42)); // error // call with a lambda expression func( [](void)->int {return 42;} ); func_wrapper( [](void)->int {return 42;} ); return 0; } I'm getting a compile errors deep in the C++ headers: functional:1137: error: invalid initialization of reference of type ‘int (&)()’ from expression of type ‘int (*)()’ functional:1137: error: conversion from ‘int’ to non-scalar type ‘std::_Bind(bar, int)’ requested func_wrapper(foo) is supposed to execute func(doit(foo)). In the real code it packages the function for a thread to execute. func would the function executed by the other thread, doit sits in between to check for unhandled exceptions and to clean up. But the additional bind in func_wrapper messes things up...

  • Team Foundation Server 2010 and Offline development?

    - by Bobby Ortiz
    Did Microsoft add anything to improve offline development? I'm comparing TFS with Mercurial. Edit #1: Work Environment Details 20 Developers. 1 location. TFS 2005 is already installed, but only being used by 4 developers. Those that use TFS, are only using it for Source Control Others using VSS. :( Many small projects (Over 50 projects active) Project Team size: 1 to 3 Several employees work from home one day a week, but have VPN access There is a group of our devs that have never used TFS that are still on VSS. They are the ones pushing use to jump ship to Mercurial. Mercurial offline features is one reason they prefer it. Another reason is they just associate TFS with VSS regardless of my assertions to the contrary. We do use FogBugz and everyone agrees that it is great! This kind of excited our love for NON Microsoft products that our MUCH lighter. I don't think it is worth it.

  • MS SQL - High performance data inserting with stored procedures

    - by Marks
    Hi. Im searching for a very high performant possibility to insert data into a MS SQL database. The data is a (relatively big) construct of objects with relations. For security reasons i want to use stored procedures instead of direct table access. Lets say i have a structure like this: Document MetaData User Device Content ContentItem[0] SubItem[0] SubItem[1] SubItem[2] ContentItem[1] ... ContentItem[2] ... Right now I think of creating one big query, doing somehting like this (Just pseudo-code): EXEC @DeviceID = CreateDevice ...; EXEC @UserID = CreateUser ...; EXEC @DocID = CreateDocument @DeviceID, @UserID, ...; EXEC @ItemID = CreateItem @DocID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... ... But is this the best solution for performance? If not, what would be better? Split it into more querys? Give all Data to one big stored procedure to reduce size of query? Any other performance clue? I also thought of giving multiple items to one stored procedure, but i dont think its possible to give a non static amount of items to a stored procedure. Since 'INSERT INTO A VALUES (B,C),(C,D),(E,F) is more performant than 3 single inserts i thought i could get some performance here. Thanks for any hints, Marks
