• Aggregate survey results recursively by manager

  - by Ian Roke

  I have a StaffLookup table which looks like this. UserSrn | UserName | ManagerSrn =============================== ABC1 | Jerome | NULL ABC2 | Joe | ABC1 ABC3 | Paul | ABC2 ABC4 | Jack | ABC3 ABC5 | Daniel | ABC3 ABC6 | David | ABC2 ABC7 | Ian | ABC6 ABC8 | Helen | ABC6 The staff structure looks like this. |- Jerome | |- Joe || ||- Paul ||| |||- Jack ||| |||- Daniel || ||- David ||| |||- Ian ||| |||- Helen I have a list of SurveyResponses that looks like this. UserSrn | QuestionId | ResponseScore ==================================== ABC2 | 1 | 5 ABC2 | 3 | 4 ABC4 | 16 | 3 ... What I am trying to do sounds pretty simple but I am struggling to find a neat, quick way of doing it. I want to create a sproc that takes an Srn and returns back all the staff under that Srn in the structure. If there is a score for QuestionId of 16 then that indicates a completed survey. I would like to return a line for the Srn entered (The top manager) with a count of completed surveys for the direct reports under that manager. Under that I would like each manager under the original manager with a count of completed surveys for each of their direct reports and so on. I would like to see the data as such below when I set the top manager to be Joe (ABC2). UserName | Completed | Total ============================ Joe | 2 | 2 Paul | 1 | 2 David | 0 | 2 TOTAL | 3 | 6

• How to write a custom solution using a python package, modules etc

  - by morpheous

  I am writing a packacge foobar which consists of the modules alice, bob, charles and david. From my understanding of Python packages and modules, this means I will create a folder foobar, with the following subdirectories and files (please correct if I am wrong) foobar/ __init__.py alice/alice.py bob/bob.py charles/charles.py david/david.py The package should be executable, so that in addition to making the modules alice, bob etc available as 'libraries', I should also be able to use foobar in a script like this: python foobar --args=someargs Question1: Can a package be made executable and used in a script like I described above? Question 2 The various modules will use code that I want to refactor into a common library. Does that mean creating a new sub directory 'foobar/common' and placing common.py in that folder? Question 3 How will the modules foo import the common module ? Is it 'from foobar import common' or can I not use this since these modules are part of the package? Question 4 I want to add logic for when the foobar package is being used in a script (assuming this can be done - I have only seen it done for modules) The code used is something like: if __name__ == "__main__": dosomething() where (in which file) would I put this logic ?

• How do I solve an unresolved external when using C++ Builder packages?

  - by David M

  I'm experimenting with reconfiguring my application to make heaving use of packages. Both I and another developer running a similar experiment are running into a bit of trouble when linking using several different packages. We're probably both doing something wrong, but goodness knows what :) The situation is this: The first package, PackageA.bpl, contains C++ class FooA. The class is declared with the PACKAGE directive. The second package, PackageB.bpl, contains a class inheriting from FooA, called FooB. It includes FooB.h, and the package is built using runtime packages, and links to PackageA by adding a reference to PackageA.bpi. When building PackageB, it compiles fine but linking fails with a number of unresolved externals, the first few of which are: [ILINK32 Error] Error: Unresolved external '__tpdsc__ FooA' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external 'FooA::' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external '__fastcall FooA::~FooA()' referenced from blah\FooB.OBJ etc. Running TDump on PackageA.bpl shows: Exports from PackageA.bpl 14 exported name(s), 14 export addresse(s). Ordinal base is 1. Sorted by Name: RVA Ord. Hint Name -------- ---- ---- ---- 00002A0C 8 0000 __tpdsc__ FooA 00002AD8 10 0001 __linkproc__ FooA::Finalize 00002AC8 9 0002 __linkproc__ FooA::Initialize 00002E4C 12 0003 __linkproc__ PackageA::Finalize 00002E3C 11 0004 __linkproc__ PackageA::Initialize 00006510 14 0007 FooA:: 00002860 5 0008 FooA::FooA(FooA&) 000027E4 4 0009 FooA::FooA() 00002770 3 000A __fastcall FooA::~FooA() 000028DC 6 000B __fastcall FooA::Method1() const 000028F4 7 000C __fastcall FooA::Method2() const 00001375 2 000D Finalize 00001368 1 000E Initialize 0000610C 13 000F ___CPPdebugHook So the class definitely seems to be exported and available to link. I can see entries for the specific things ILink32 says it's looking for and not finding. Running TDump on the BPI file shows similar entries. Other info The class does descend from TObject, though originally before refactoring into packages it was a normal C++ class. (More detail below. It seems "safer" using VCL-style classes when trying to solve problems with a very Delphi-ish thing like this anyway. Changing this only changes the order of unresolved externals to first not find Method1 and Method2, then others.) Declaration for FooA: class PACKAGE FooA: public TObject { public: FooA(); virtual __fastcall ~FooA(); FooA(const FooA&); virtual __fastcall long Method1() const; virtual __fastcall long Method2() const; }; and FooB: class FooB: public FooA { public: FooB(); virtual __fastcall ~FooB(); ... other methods... }; All methods definitely are implemented in the .cpp files, so it's not not finding them because they don't exist! The .cpp files also contain #pragma package(smart_init) near the top, under the includes. Questions that might help... Are packages reliable using C++, or are they only useable with Delphi code? Is linking to the first package by adding a reference to its BPI correct - is that how you're supposed to do it? I could use a LIB but it seems to make the second package much larger, and I suspect it's statically linking in the contents of the first. Can we use the PACKAGE directive only on TObject-derived classes? There is no compiler warning using it on standard C++ classes. Is splitting code into packages the best way to achieve the goal of isolating code and communicating through defined layers / interfaces? I've been investigating this path because it seems to be the C++Builder / Delphi Way, and if it worked it looks attractive. But are there better alternatives? I'm very new to using packages and have only known about them through using components before. Any general words of advice would be great! We're using C++Builder 2010. I've fabricated the class and method names in the above code examples, but other than that the details are exactly what we're seeing. Cheers, David

• using xml type attribute for derived complex types

  - by David Michel

  Hi All, I'm trying to get derived complex types from a base type in an xsd schema. it works well when I do this (inspired by this): xml file: <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> xsd file: <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> However, if I want to have the person element inside, for example, a sequence of another complex type, it doesn't work anymore: xml: <staffRecord> <company>mycompany</company> <dpt>sales</dpt> <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> </staffRecord> xsd file: <xs:element name="staffRecord"> <xs:complexType> <xs:sequence> <xs:element name="company" type="xs:string"/> <xs:element name="dpt" type="xs:string"/> <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:sequence> </xs:complexType> </xs:element> When validating the xml with that schema with xmllint (under linux), I get this error message then: config.xsd:12: element complexType: Schemas parser error : Element '{http://www.w3.org/2001/XMLSchema}sequence': The content is not valid. Expected is (annotation?, (element | group | choice | sequence | any)*). WXS schema config.xsd failed to compile Any idea what is wrong ? David

• flex and jsf access the same instance of bean

  - by David

  i integrate a flex app in a jsf-icefaces app (in a jspx site with the ice:outputmedia-tag) and want to access the same instance of a bean from flex by remote, that jsf inject. i already connect with blazeds to a java-bean. this bean - like all other beans - get other beans by injection of jsf, but when i access the bean by remote from flex it doesnt hold the injected beans (like localizer and accesmanager, both session scoped) and i can't connect to the jsf session (FacesContext.getCurrentInstance() is null). this is because flex create a new instance of the bean and it’s not the same current instance, that jsf inject, i think. i can connect from flex to the database by create a new entity manager in the java bean, but that's not what i want, because it's again another entity manager...i want persist and get data over the accessmanager-bean. i know exadel fiji and flamingo, but i couldn't work with fiji, because my jsf app include the icefaces components and then it doesn't work with richfaces which fiji needs. and flamingo work only with jboss seam and spring. is it right? i also read about the spring-flex-integration, but the jsf application did not create with spring and i don't want to integrate spring in such a large jsf app. yesterday i read about the FlexFactory interface. this interface i have to implement in my own Factory and set it in the service-config.xml of blazeds as a factory read this. i still implement my own factory but i only get application scoped beans over the servlet context which i get over FlexContext.getServletContext().getAttribute("Bean"); and not session scoped beans... i hope there is a chance to connect throw flex and jsf... thanks!

• Is it valid to use unsafe struct * as an opaque type instead of IntPtr in .NET Platform Invoke?

  - by David Jeske

  .NET Platform Invoke advocates declaring pointer types as IntPtr. For example, the following [DllImport("user32.dll")] static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, Int32 wParam, Int32 lParam); However, I find when interfacing with interesting native interfaces, that have many pointer types, flattening everything into IntPtr makes the code very hard to read and removes the typical typechecking that a compiler can do. I've been using a pattern where I declare an unsafe struct to be an opaque pointer type. I can store this pointer type in a managed object, and the compiler can typecheck it form me. For example: class Foo { unsafe struct FOO {}; // opaque type unsafe FOO *my_foo; class if { [DllImport("mydll")] extern static unsafe FOO* get_foo(); [DllImport("mydll")] extern static unsafe void do_something_foo(FOO *foo); } public unsafe Foo() { this.my_foo = if.get_foo(); } public unsafe do_something_foo() { if.do_something_foo(this.my_foo); } While this example may not seem different than using IntPtr, when there are several pointer types moving between managed and native code, using these opaque pointer types for typechecking is a godsend. I have not run into any trouble using this technique in practice. However, I also have not seen an examples of anyone using this technique, and I wonder why. Is there any reason that the above code is invalid in the eyes of the .NET runtime? My main question is about how the .NET GC system treats "unsafe FOO *my_foo". Is this pointer something the GC system is going to try to trace, or is it simply going to ignore it? My hope is that because the underlying type is a struct, and it's declared unsafe, that the GC would ignore it. However, I don't know for sure. Thoughts?

• xPath Groupings how?

  - by David

  OK So, I'm learning/using xpath for a basic application thats effectively ripping data off another website. I need to gain the knowledge of each persons Countryy/Suburb/area. In some instances you can get Australia/Victoria/melborne for instance. Others may just be Australia/Melbourne. Or even just Melbourne OR just AUSTRALIA. who knows. So I'm current able to view the below code and rip all of the information with the string xpath search:@" //table/tr/td/tabke/tr/td/font/a, this returns every entry, but what I really want is to group each lot separately. I hope someone out there on planet earth knows what I just tried to explain... and can help...

• Clickonce redirect

  - by David Hagan

  Is it possible to deploy an application (using an existing clickonce deployment URL, such that users update to that version) which changes the deployment URL of the deployed application? The scenario is that I have a deployed client (A), which is stable and has been in use for over a year, and a new client (B), which is in development and will be used. However, B and A have different UIDs so that they can both be deployed on the same system together. At some point in the future, I'd like to automatically migrate users who have been using A to B, but I'd hope that Clickonce is well-designed enough to not upgrade A to B if I place B's install files in A's install directory (because it should be checking those UIDs). I know that a C# application that's been deployed through clickonce has some access to its own deployment method, and I'm wondering whether I'm able to change the upgrade-location. I'm hoping to do this quietly without much involvement of the user (and I understand that quiet redirects are heavily frowned upon, for good reasons) and am wondering whether anyone has any experience of trying to modify an installed clickonce's deployment/upgrade information with an update.

• Observer Design Pattern - multiple event types

  - by David

  I'm currently implementing the Observer design pattern and using it to handle adding items to the session, create error logs and write messages out to the user giving feedback on their actions (e.g. You've just logged out!). I began with a single method on the subject called addEvent() but as I added more Observers I found that the parameters required to detail all the information I needed for each listener began to grow. I now have 3 methods called addMessage(), addStorage() and addLog(). These add data into an events array that has a key related to the event type (e.g. log, message, storage) but I'm starting to feel that now the subject needs to know too much about the listeners that are attached. My alternative thought is to go back to addEvent() and pass an event type (e.g. USER_LOGOUT) along with the data associated and each Observer maintains it's own list of event handles it is looking for (possibly in a switch statement), but this feels cumbersome. Also, I'd need to check that sufficient data had also been passed along with the event type. What is the correct way of doing this? Please let me know if I can explain any parts of this further. I hope you can help and see the problem I'm battling with.

• Conflicting answers from du with different units

  - by dpitch40

  My question is quite simple. I get this output when checking the total amount of space I'm using on my Walkman. david@Milton:/media$ du -b --max-depth=0 WALKMAN/ 14823290693 WALKMAN/ david@Milton:/media$ du -k --max-depth=0 WALKMAN/ 14523776 WALKMAN/ Last I checked, 14,523,776 KB * 1024 = 14,872,646,624 B, not 14,823,290,693. Dividing the two, their "K" unit seems to be equal to about 1020.62 rather than 1024 as advertised. This is causing some errors in the program I wrote to sync my Walkman, so it fills up faster than it claims to. Can anyone explain this discrepency?

• Nested IF's in Excel

  - by user1590499

  I have two columns with the following possibilities (0 for first column, and then 0 or 1 for second column; or a string for first column, and a 0 or 1 for second column). name,flag 0,0 david,0 0,1 sammy,1 How would I create a third column that looks like the following: name+flag 0 david 1 sammy Basically, if there are 2 0's in the two columns in a row, put a 0 in the new column. if there is a string in the first column in the row, no matter what the second column in the row says, put the string in the new column. and if there is a 0 in the first column and a 1 on the second column, put a 1 in the third column. Can I do this best with nested-if's? I tried something like name, flag, name+flag 0,0,=IF(A2<>0,A2,IF(B2=1,B2,0),0) But it didn't seem to work for me...

CompositionTarget.Rendering and RenderEventArgs Charles Petzold talks about CompositionTarget.Rendering and using it for calculating time span ... and it works in WPF and WP7 too... cool example from his WPF book, and all the code. Two small issues with Windows Phone 7 ApplicationBar buttons (and workaround) Laurent Bugnion has a post up from earlier this week that I missed describing problems with the WP7 ApplicationBar ... oh, and a workaround for it :) Animation in Silverlight Anjaiah Keesari has a really extensive post up on Silverlight animation, and this is an all-XAML thing... so buckle up we're going old-school :) Two fixes for my Silverlight SplitButton/MenuButton implementation - and true WPF support David Anson revisits and revises his SplitButton code based on a couple problem reports he received. Source for the button and the test project is included. Tips and Tricks for INotifyPropertyChanged Jeremy Likness is discussing INotifyPropertyChanged and describes an extension method. He does bring up a problem associated with this, so check that out. He finishes the post off with a discussion of "Observable Enumerables" Stay in the 'Light!
