• How to scan and count controls present in DataAccessPage of Access DataBase programmatically?

  - by Suman

  As per my application (Vb.net), it scans the Access database for Active-X controls. It is working now for Report form and Access Form. The code to find out controls is as follows: oReportCtls = oReport.Controls For Each oReportCtl In oReportCtls If oReportCtl.ControlType = 119 Then 'Activex Control' intReportObjectCount = intReportObjectCount + 1 End If Next But for DataAccessPages I am not getting any reference for Controls. Need Help: Please let me know it is possible or not? If yes, then please provide me some reference or example. Many Many Thanks, Sugam

• Shared static classes between AppDomains in loaded library code

  - by Christian Stewart

  I'm working on a program in which I want to do something similar to what the Photon Server system does: Offer a common "API" class library, which contains common data classes, enumerations, and interfaces for working with the host program. Have client programs (class libraries) reference this DLL and implement interfaces listed within it. Have the "host" application load built DLL client libraries into separate AppDomains and reference the interfaces that lie within to have polymorphic client code from within a dll file. I have something like this worked out: a class library that contains common code, but I've run into the following question How should I handle static classes? Should I add a method that is called by the host program to synchronize data? How do I keep a static class the same between AppDomains? Should I discard these classes in favor of better interfaces between the code levels? And in general, how do I share data between these loaded AppDomains?

• ASP.NET Compiles on page load, but not on Ctrl+Shift+B

  - by Steve Syfuhs

  during debug in cassini the code runs fine, but when I explictly build it, the compile breaks on an object saying it can't find the reference. During a breakpoint shows the proper reference to the object, and I can view the debug intellisense. The code itself is simple using CFTW.Controls; ... controls_LatestPresentations c = LoadControl("~/controls/LatestPresentations.ascx") as controls_LatestPresentations; c.loadContent(); return RenderControl(c); The control is a simple user control, with the namespace CFTW.Controls. The calling code is in a webcontrol, which lives in the same folder. I even tried adding the calling code to the same namespace.

• Silverlight calling windows workflow foundation as a web service

  - by wissem

  hi, I'm trying to call a windows workflow foundation published as a web service from a Silverlight project. When I call it from a console application it works fine because I can add a web reference then I just make an instance of that webservice then I invoke the method I want. The problem is in the silverlight project cause i can just add a service reference so I find myself working with soap stuff that doesn't work at all, and here is the code: private void btnUpdate_Click(object sender, RoutedEventArgs e) { xxxxxxx.Workflow1_WebServiceSoapClient zer = new xxxxx.Workflow1_WebServiceSoapClient(); zer.demanderSubmitReportCompleted += new EventHandler<xxxxxxxxxxxxxxx.demanderSubmitReportCompletedEventArgs>(service2); zer.demanderSubmitReportAsync("zzz", 20000); } public void service2(object sender, xxxxx.demanderSubmitReportCompletedEventArgs e) { string a = e.Result; } plz help ,thanks

• Any way to optimize this MySQL query?

  - by manyxcxi

  My table looks like this: `MyDB`.`Details` ( `id` bigint(20) NOT NULL, `run_id` int(11) NOT NULL, `element_name` varchar(255) NOT NULL, `value` text, `line_order` int(11) default NULL, `column_order` int(11) default NULL ); I have the following SELECT statement in a stored procedure SELECT RULE ,TITLE ,SUM(IF(t.PASSED='Y',1,0)) AS PASS ,SUM(IF(t.PASSED='N',1,0)) AS FAIL FROM ( SELECT a.line_order ,MAX(CASE WHEN a.element_name = 'PASSED' THEN a.`value` END) AS PASSED ,MAX(CASE WHEN a.element_name = 'RULE' THEN a.`value` END) AS RULE ,MAX(CASE WHEN a.element_name = 'TITLE' THEN a.`value` END) AS TITLE FROM Details a WHERE run_id = runId GROUP BY line_order ) t GROUP BY RULE, TITLE; *runId is an input parameter to the stored procedure. This query takes about 14 seconds to run. The table has 214856 rows, and the particular run_id I am filtering on has 162204 records. It's not on a super high power machine, but I feel like I could be doing this more efficiently. My main goal is to summarize by Rule and Title and show Pass and Fail count columns.

• Is it acceptable to email an Interviewer after the interview?

  - by djhworld

  Yesterday I took part in an interview for a Java position in a company and one of the questions was Does Java pass by reference or by value? In the heat of the moment I (mistakenly) confidently said it passed by reference, possibly because I come from a C/C++ background. Unfortunately after the interview I'd realised my terrible mistake to my horror. So my question is this, is it acceptable for me to wait a few days and drop a quick email to recognise my mistake? Or should I just let this one lie?

• How to call same method for a list of objects?

  - by Dmitry

  Suppose code like this: class Base: def start(self): pass def stop(self) pass class A(Base): def start(self): ... do something for A def stop(self) .... do something for A class B(Base): def start(self): def stop(self): a1 = A(); a2 = A() b1 = B(); b2 = B() all = [a1, b1, b2, a2,.....] Now I want to call methods start and stop (maybe also others) for each object in the list all. Is there any elegant way for doing this except of writing a bunch of functions like def start_all(all): for item in all: item.start() def stop_all(all): .....

• Calling web service methods using URLs

  - by Alka

  Hi. So, i have a central web service that is responsible for managing other services. These services register in the main WS with their URL, leading to their own web service. what i need to do now is call the child web services from the central web service. I've searched google on how to do this but all i could find was this. I would like to register any web service and not create a web reference, as suggested in the solution i've found. How is this done without using a web reference?

• Passing javascript form variables into jQuery function not working

  - by Chase

  I am trying to pass some JavaScript variables that I have assigned to form variables into a query string used by a jQuery plug in called fancybox. If I hard code in the string that I want lightbox works great, however I need it to pass some form values in there to make it work as desire. <script type="text/javascript"> $(document).ready(function(){ var item = document.itemFinder.item; var zip = document.itemFinder.zip; var radius = document.itemFinder.radius; var dataString = "item=" + item + "&zip=" + zip + "&radius=" + radius; $("#various3").fancybox({ ajax : { type : "POST", data : dataString}, 'scrolling' : 'auto', 'overlayOpacity' : '0' } ); }); </script> What am I doing wrong?

• Resources for memory management in embedded application

  - by Elazar Leibovich

  How should I manage memory in my mission critical embedded application? I found some articles with google, but couldn't pinpoint a really useful practical guide. The DO-178b forbids dynamic memory allocations, but how will you manage the memory than? preallocate everything in advance and send a pointer to each function that needs allocation? Allocate it on the stack? Use a global static allocator (but then it's very similar to dynamic allocation)? Answers can be of the form of regular answer, reference to a resource, or reference to good opensource embedded system for example. clarification: The issue here is not whether or not memory management is availible for the embedded system. But what is a good design for an embedded system, to maximize reliability.

• Map browser DOM using Javascript

  - by EddyR

  I'm trying to map a browsers DOM using javascript. It should list all the functions and attributes associated with it and it should also recurse through any object attributes. Now as I understand it 'window' is the most top-level node (although I've see a reference to 'top' as well in Chrome.) then 'document', etc. However I've never seen 'Node' under 'window' and yet I can call it. So where is 'Node' located? Is there a level above 'window' or is it a separate object (W3C says it's supposed to be inherited by 'document' only.)? I've been playing with a function to do this but I keep getting weird results so I'm not post it here. Alternatively - is it possible to get the properties from the object types instead of the object reference itself? for example 'DOMWindow' instead of 'window'. I think this would stop duplicating data from inherited objects.

• Dynamically load a type from an external assembly

  - by Water Cooler v2

  From managed code, how do I load a managed type from another assembly at runtime, assuming the calling code does not have a static reference to the assembly? To clarify, let's say I have class Lib in Lib.cs compiled into Lib.dll. I want to write a class Foo in a separate assembly called Foo.dll, that does not have a reference to Lib.dll statically, but instead loads Lib.dll and then reflects on for the presence of the class Lib and then calls a method on it. Sorry for such an obvious question on Reflection. I figure it'll take much lesser time to get the answer on a forum that to read a few articles.

• Build Event Macros for Other Projects in the Solution

  - by Adam Driscoll

  Is it possible to reference other projects' properties via a macro within a build event? For example: "Tool1" outputs to directory ..\..\bin\Release "Component1" uses "Tool1" in its post-buildevent To get to "Tool1", "Component1"'s project must do something like $(SolutionDir)bin\Release This requires that Tool1 always output to ..\..\bin\Release. If this is changed this breaks the other project. I know there is no indication to this within the macro list but is there a way to reference another project? Maybe like $(OtherProject.TargetDir)... I know WIX has a similar syntax [$(var.OtherProject.TargetDir)] but I think that may be a different mechanism.

• Iterator category

  - by Knowing me knowing you

  In code: //I know that to get this effect (being able to use it with std algorithms) I can inherit like I did in line below: class Iterator //: public std::iterator<std::bidirectional_iterator_tag,T> { private: T** itData_; public: //BUT I WOULD LIKE TO BE ABLE TO DO IT BY HAND AS WELL typedef std::bidirectional_iterator_tag iterator_category; typedef T* value_type;//SHOULD IT BE T AS value_type or T*? typedef std::ptrdiff_t difference_type; typedef T** pointer;//SHOULD IT BE T* AS pointer or T**? typedef T*& reference;//SHOULD IT BE T& AS reference or T*&? }; Basically what I'm asking is if I have my variable of type T** in iterator class is it right assumption that value type for this iterator will be T* and so on as I described in comments in code, right next to relevant lines. Thank you.

  hi all, I have 2 pools of threads ioThreads = (ThreadPoolExecutor)Executors.newCachedThreadPool(); cpuThreads = (ThreadPoolExecutor)Executors.newFixedThreadPool(numCpus); I have a simple web crawler that I want to create an iothread, pass it a url, it will then fetch the url and pass the contents over to a cpuThread to be processed and the ioThread will then fetch another url, etc... At some point the IO thread will not have any new pages to crawl and I want to update my database that this session is complete. How can I best tell when the threads are all done processing and the program can be ended?

• amp is included in url struts tag

  - by lakshmanan

  Hi, In my web application, I use strust2 url tag to pass parameters like id etc., For example, I use a link to delete an entity and I use param to pass the id of the entity to be deleted. And I follow this throughout my web app for adding, editing, deleting an entity. During run time, sometimes, I don't get the params to be stored in my action's bean properties. When I see the link that is generated, I get something like <a href='/projit1/p/discuss/viewDiscussion.action?d=11&amp;amp;amp;projid=11&amp;amp;disid=4'> What are these amps for ? why do they sit in between the action calls (made by link via url tag actions ) ? By the time I traverse back and forth in my web app, I get 10s and 20s of amp sitting in the request URL. What is the problem here ? Please help.

• Why this java application print "true"?

  - by user292084

  This is my first Class Hello.java public class Hello { String name = ""; } This is my second Class Test1.java public class Test1 { public static void main(String[] args) { Hello h = new Hello(); Test1 t = new Test1(); t.build(h); System.out.println((h.name)); } void build(Hello h){ h.name = "me"; } } When I run Test1.java, it prints "me". I think I understand, because of "reference transfer". This is my third Class Test2.java public class Test2 { public static void main(String[] args) { Hello h = null; Test2 t = new Test2(); t.build(h); System.out.println(((h == null))); } void build(Hello h){ h = new Hello(); } } When I run Test2.java, it prints "true", why ? Is it "reference transfer" no longer? I am confused.

• Serialize Dictionary with a string key and List[] value to JSON

  - by Patrick

  How can I serialize a python Dictionary to JSON and pass back to javascript, which contains a string key, while the value is a List (i.e. []) if request.is_ajax() and request.method == 'GET': groupSet = GroupSet.objects.get(id=int(request.GET["groupSetId"])) groups = groupSet.groups.all() group_items = [] #list groups_and_items = {} #dictionary for group in groups: group_items.extend([group_item for group_item in group.group_items.all()]) #use group as Key name and group_items (LIST) as the value groups_and_items[group] = group_items data = serializers.serialize("json", groups_and_items) return HttpResponse(data, mimetype="application/json") the result: [{"pk": 5, "model": "myApp.group", "fields": {"name": "\u6fb4\u9584", "group_items": [13]}}] while the group_items should have many group_item and each group_item should have "name", rather than only the Id, in this case the Id is 13. I need to serialize the group name, as well as the group_item's Id and name as JSON and pass back to javascript. I am new to Python and Django, please advice me if you have a better way to do this, appreciate. Thank you so much. :)

• java memory usage

  - by xdevel2000

  I know I always post a similar question about array memory usage but now I want post the question more specific. After I read this article: http://www.javamex.com/tutorials/memory/object_memory_usage.shtml I didn't understand some things: the size of a data type is always the same also on different platform (Linux / Windows 32 / 64 bit)??? so an int will be always 32 bit?; when I compute the memory usage I must put also the reference value itself? If I have an object to a class that has an int field its memory will be 12 (object header) + 4 reference + 4 (the int field) + 3 (padding) = 24 bytes??

• Visual C++ 2008: Finding the cause of slow link times

  - by ckarras

  I have a legacy C++ project that takes an annoyingly long time to build (several minutes, even for small incremental changes), and I found most of the time was spent linking. The project is already using precompiled headers and incremental compilation. I have enabled the "/time" command line parameter in the hope I would get more details about what is slowing the linker, and got the following output: 1>Linking... 1> MD Merge: Total time = 59.938s 1> Generate Transitions: Total time = 0.500s 1> MD Finalize: Total time = 7.328s 1>Pass 1: Interval #1, time = 71.718s 1>Pass 2: Interval #2, time = 8.969s 1>Final: Total time = 80.687s 1>Final: Total time = 80.953s Is there a way to get more details about each of these steps? For example, I would like to find if they are spending most time linking to a specific .lib or .obj file. Also, is there any documentation that explains what each of these steps do?

• bulk update/delete entities of different kind in db.run_in_transaction

  - by Ray Yun

  Here goes pseudo code of bulk update/delete entities of different kind in single transaction. Note that Album and Song entities have AlbumGroup as root entity. class AlbumGroup: pass class Album: group = db.ReferenceProperty(reference_class=AlbumGroup,collection_name="albums") class Song: album = db.ReferenceProperty(reference_class=Album,collection_name="songs") def bulk_update_album_group(album_group): updated = [album_group] deleted = [] for album in album_group.albums: updated.append(album) for song in album.songs: if song.is_updated: updated.append(song) if song.is_deleted: deleted.append(song) db.put(updated) db.delete(deleted) a = AlbumGroup.all().filter("...").get() # bulk update/delete album group. for simplicity, album cannot be deleted. db.run_in_transaction(bulk_update_album_group,a) But I met a famous "Only Ancestor Queries in Transactions" error at the iterating reference properties like album.songs or album_group.albums. I guess ancestor() filter does not help because those entities are modified in memory. Should I not to iterate reference property in transaction function and always provide them as function parameters like def bulk_update_album_group(updated,deleted): ??? Is there any good coding pattern for this situation?
