• Google Local Search API

  - by Gublooo

  hey guys couple of quick questions 1) In the local search results - we can get a lot of parameters like street title, address, city, state, lat, long , url etc - In order for me to uniquely identify this record - can I consider URL to be unique to this address or concatenation of latitude and longitude Ref: http://code.google.com/apis/ajaxsearch/documentation/reference.html#_class_GlocalResult 2) In terms of usage, depending upon what user enters, I'm displaying a list of local business for the user to choose. Now when a user selects a particular business address - is it legal for me to store that business address along with lat and longitude information in my database for future look ups. I've seen a lot of blogs talking about storing the lat/long info but just want to be sure that i'm not violating and google rules. Thanks

• Help with query

  - by hdoe123

  Hi, I'm trying make a query that looks at a single table and looks to see if a student is a team called CMHT and in a medic team - if they are I don't want to see the result. I only want see if there only in CMHT or medic not both. Would the right direction be using sub query to filer it out? I've done a search on NOT IN but how could you get to see check if its in more then 2 teams are not? Student Team ref 1 CMHT 1 1 Medic 2 2 Medic 3 this would be in the result 3 CMHT 5 this would be in the result So far I've done the following code would I need use a sub query or do a self join and filter it that way? SELECT Table1.Student, Table1.Team, Table1.refnumber FROM Table1 WHERE (((Table1.Team) In ('Medics','CMHT'))

• What is an example of a website/service which _isn't_ REST?

  - by montooner

  So I just started digging into web tech, and I'm stuck on the concept of REST. Could someone clarify REST by giving me an example of what isn't rest? So, as far as I can tell, REST requires the server and client to both be in the same state at the end of every request-response HTTP transfer. Does that sound right? My understanding is that, if a client stores state information locally (which the server does not know about), that service is NOT rest. Thanks in advance.

• Build dynamic LINQ?

  - by d daly

  Hi Im using #LINQ# to query data, but can anyone tell me how to build the query dynamically, if the user only wants to report on say 1 of the 3 fields?

• .Net with single .exe without .NET Framework installation

  - by user156144

  I wrote my simple desktop program in C#. I am reluctant to distribute it on the internet because i am not sure if users will go through pain of installing the .Net Framework. My target users are non-tech savvy users. I am very familiar with MFC and I probably can write this program in MFC in a month. MFC is nice because I don't have to worry about distributing other components. It will be one nice single executable. So my real question is this: Is it possible to write .Net app without worrying about distributing .Net Framework? Update I found another solution: If you are using Innosetup, there is a script that installs .net framework. http://www.codeproject.com/KB/install/dotnetfx_innosetup_instal.aspx

• Which are your favorite programming language gadgets?

  - by FerranB

  There are some gadgets/features for programming languages that I like a lot because they save a lot of coding or simply because they are magical or nice. Some of my favorites are: C++ increment/decrement operator: my_array[++c]; C++ assign and sum or substract (...): a += b C# yield return: yield return 1; C# foreach: foreach (MyClass x in MyCollection) PLSQL for loop: for c in (select col1, col2 from mytable) PLSQL pipe row: for i in 1..x loop pipe row(i); end loop; Python Array access operator: a[:1] PLSQL ref cursors. Which are yours?

• Implementing a two-way communication between Microsoft Dynamics CRM and 3rd party app

  - by CxDoo

  I need to implement a bi-directional communication between Microsoft Dynamics CRM and a 3rd party server. The ideal scenario is as follows: User tries to create an entity in CRM In pre-create hook a 3rd party library function is called (or web service or whatever), filled with relevant info, which tries to create the respective entity on the server If the call fails, creation fails in CRM If the call succeeds, the entity is created in the CRM AND additional fields are filled with return values from the call More specifically, I want to do something like this when user tries to create a new entity instance: try { ExternalWebService.CreateTrade(ref TradeInfo info) //this was initialized on the external server myCRM_Trade_Entity.SerialNo = info.SerialNo; CreateNew(myCRM_Trade_Entity); } catch (whatever) { fail; } What would be the suggested way to do this? I am new to Dynamics, have read about Workflows and Plugins but am not sure how should I do this properly.

• Can DBRefs contain additional fields?

  - by Soviut

  I've encountered several situations when using MongoDB that require the use of DBRefs. However, I'd also like to cache some fields from the referenced document in the DBRef itself. {$ref:'user', $id:'10285102912A', username:'Soviut'} For example, I may want to have the username available even though the user document is referenced. This would provide me all the benefits of a single document approach; Faster querying and eliminating the need to do manual dereferencing in my code. While at the same time allowing me to use references where they make sense. The idea being that when the referenced document is updated (a user changes their name, for example) my business layer can automatically update all the documents that reference it. Ultimately, I'm wondering if it's considered good form to store additional fields on my DBRefs? Will it break anything? Will I lose my data each time a reference is rewritten? Will drivers like pymongo support it?

• Spring - using static final fields (constants) for bean initialization

  - by lisak

  Hey, is it possible to define a bean with the use of static final fields of CoreProtocolPNames class like this: <bean id="httpParamBean" class="org.apache.http.params.HttpProtocolParamBean"> <constructor-arg ref="httpParams"/> <property name="httpElementCharset" value="CoreProtocolPNames.HTTP_ELEMENT_CHARSET" /> <property name="version" value="CoreProtocolPNames.PROTOCOL_VERSION"> </bean> public interface CoreProtocolPNames { public static final String PROTOCOL_VERSION = "http.protocol.version"; public static final String HTTP_ELEMENT_CHARSET = "http.protocol.element-charset"; } If it is possible, what is the best way of doing this ?

• What is the best way to marshal a char array function argument?

  - by Seh Hui 'Felix' Leong

  Let say that given the following signature in LegacyLib.dll: int Login(SysInst *inst, char username[8], char password[6]); The simple way to marshal this function in C# would be: [DllImport("LegacyLib.dll", CharSet=CharSet.Ansi)] public static extern int Login(ref SysInst inst, string username, string password); The problem of doing it in a such a naive way is that the managed string we passed into the username or password parameter could be longer than the array bounds and this could potentially cause a buffer overrun in LegacyLib.dll. Is there a better way which overcomes this problem? i.e. is there any quick [MarshalAs(…)] magic that I could use to counter that?

• Eidetic memory: What magic numbers you still remember?

  - by Hao

  Long before you practice writing readable code, what "magic numbers" you still remember up to this day? here's some of my list: 72 80 75 77 13 32 27 - up down left right enter space escape 1 2 4 128 - blue green red blink 67h 33h 17h - interrupt for EMS, mouse, printer function AH 9, interrupt 21 alt+219 for block ASCII alt+164 ñ 90 NOP 13 10 carriage return, line feed ascii 1 and 2 face, ascii 3 heart. no not this heart: <3 :-) debug -o72,10 -o71,12 clears the BIOS password. I don't know what those numbers mean, it's like a trade secret that gets shared with each other during college days. ascii 7 sounds a beep P.S. Somehow, remembering some of these magic numbers can help you in some tech problems, your keyboard is broken, the office pal's keyboard doesn't have accented characters. An anecdote, during college, one of my friend asked me how to remove the newlines in his Word document. Not having used Word so much then, I somehow "intuitively" guessed to find ^013 and replace it with blank. Well it works :-)

• Need some serious help with self join issue.

  - by kralco626

  Well as you may know, you cannot index a view with a self join. Well actually even two joins of the same table, even if it's not technically a self join. A couple of guys from microsoft came up with a work around. But it's so complicated I don't understand it!!! The solution to the problem is here: http://jmkehayias.blogspot.com/2008/12/creating-indexed-view-with-self-join.html The view I want to apply this work around to is: create VIEW vw_lookup_test WITH SCHEMABINDING AS select count_big(*) as [count_all], awc_txt, city_nm, str_nm, stru_no, o.circt_cstdn_nm [owner], t.circt_cstdn_nm [tech], dvc.circt_nm, data_orgtn_yr from ((dbo.dvc join dbo.circt on dvc.circt_nm = circt.circt_nm) join dbo.circt_cstdn o on circt.circt_cstdn_user_id = o.circt_cstdn_user_id) join dbo.circt_cstdn t on dvc.circt_cstdn_user_id = t.circt_cstdn_user_id group by awc_txt, city_nm, str_nm, stru_no, o.circt_cstdn_nm, t.circt_cstdn_nm, dvc.circt_nm, data_orgtn_yr go Any help would be greatly apreciated!!! Thanks so much in advance!

• How to extend the comments framework (django) by removing unnecesary fields?

  - by Ignacio

  Hi, I've been reading on the django docs about the comments framework and how to customize it (http://docs.djangoproject.com/en/1.1/ref/contrib/comments/custom/) In that page, it shows how to add new fields to a form. But what I want to do is to remove unnecesary fields, like URL, email (amongst other minor mods.) On that same doc page it says the way to go is to extend my custom comments class from BaseCommentAbstractModel, but that's pretty much it, I've come so far and now I'm at a loss. I couldn't find anything on this specific aspect.

• Does the WCF framework support the XSD IDREF restriction?

  - by Gerard

  A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

• .NET CF on Windows CE - problem with filtering system messages

  - by mack369

  Hello, I'm trying to get every windows message that tells that the user has touched the screen. It works everywhere, except the button, when it is disabled. It seems that the application doesn't get any message when clicked on disabled control. I'm using OpenNetCF Application2 class for filtering messages: Application2.AddMessageFilter(Device.PowerManager); Application2.Run(new MainForm()); PowerManager class contains a following method (as required by IMessageFilter interface): public bool PreFilterMessage(ref Microsoft.WindowsCE.Forms.Message m) { log.DebugFormat("windows message {0} - 0x{0:X}", m.Msg); if (m.Msg == 0x0201 || m.Msg == 0x8001 || m.Msg == 0x0005) { return this.ResetPowerManager(); } return false; } in the log file there is no indication of a windows message when clicking on disabled button. I'm wondering how is it possible and how can I get this message.

• .NET 2.0 vs .NET 4.0 loading error

  - by David Rutten

  My class library is compiled against .NET 2.0 and works just fine whenever I try to load it as a plugin under the 2.0 runtime. If however the master application is running the .NET 4.0 runtime, I get an exception as soon as the resources need to be accessed: Exception occurred during processing of command: Grasshopper Plug-in = Grasshopper Could not find file 'Grasshopper.resources'.

• Sending Subversion Change Log Info Via Hudson

  - by GrumpyCanuck

  I'm trying to integrate Hudson into our development process, and everything is going smooth except for one thing. I had been using Phing to do deployments, and one of the things that was being triggered was an email to our tech support email address containing a list of all the commit messages between the last time code was deployed and the present SVN revision. I was doing something like this: read in a file from the root directory of the currently-deployed application that contains the SVN revision when the app was deployed place that value in a Phing variable insert that value into a command to send the SVN commit messages via email create a file in the root directory of the newly-deployed application that contains the current SVN revision I'd like to be able to add that information to the email that gets sent out by Hudson when a successful build goes out. Any pointers on how to accomplish this task in Hudson would be greatly appreciated.

• CPU temperature monitoring C#

  - by Paul

  For a programming project I would like to access the temperature readings from my CPU and GPUs. I will be using C#. From various forums I get the impression that there is specific information and developer resources you need in order to access that information for various boards. I have a MSI NF750-G55 board. MSI's website does not have any of the information I am looking for. I tried their tech support and the rep I spoke with stated they do not have any such information. There must be a way to obtain that info. Any thoughts?

• How to read a technical book to remember most of it?

  - by LikeToCode

  There are many technical books that become thinker and thicker and the pressure from the technical society is more and more to read them and remember many concepts described in them. But it's so hard to do it. I have only a few hour a week to read them and when I reach the middle of the book I forgot most of what I've read at the beginning, because lots of time passed. If I go back, I'll just re-read the same stuff over and over, never going past 50% of the book. So, even after I finished reading a thick tech book I forgot most of it. How do you remember all that stuff? I had a talk in my University on how to do it. They advised to use some cards with basic info so that you can remember the details when you look at it. Do you use such cards or do you have other ideas how to do it?

• Is this a correct Interlocked synchronization design?

  - by Dan Bryant

  I have a system that takes Samples. I have multiple client threads in the application that are interested in these Samples, but the actual process of taking a Sample can only occur in one context. It's fast enough that it's okay for it to block the calling process until Sampling is done, but slow enough that I don't want multiple threads piling up requests. I came up with this design (stripped down to minimal details): public class Sample { private static Sample _lastSample; private static int _isSampling; public static Sample TakeSample(AutomationManager automation) { //Only start sampling if not already sampling in some other context if (Interlocked.CompareExchange(ref _isSampling, 0, 1) == 0) { try { Sample sample = new Sample(); sample.PerformSampling(automation); _lastSample = sample; } finally { //We're done sampling _isSampling = 0; } } return _lastSample; } private void PerformSampling(AutomationManager automation) { //Lots of stuff going on that shouldn't be run in more than one context at the same time } } Is this safe for use in the scenario I described?

Below is my code for ur ref: CalendarService myService = new CalendarService("My Application"); myService.setUserCredentials(args[0],args[1]); // Set up the URL and the object that will handle the connection: URL feedUrl = new URL("http://www.google.com/calendar/feeds/"+args[0]+"/private/full"); args[0] & args[1] are the credentials. AuthenticationException will be thrown when calling myService.setUserCredentials(). Anybody has any clue?

• Search object array for matching possible multiple values using different comparison operators

  - by Sparkles

  I have a function to search an array of objects for a matching value using the eq operator, like so: sub find { my ( $self, %params ) = @_; my @entries = @{ $self->{_entries} }; if ( $params{filename} ) { @entries = grep { $_->filename eq $params{filename} } @entries; } if ( $params{date} ) { @entries = grep { $_->date eq $params{date} } @entries; } if ( $params{title} ) { @entries = grep { $_->title eq $params{title} } @entries; } .... I wanted to also be able to pass in a qr quoted variable to use in the comparison instead but the only way I can think of separating the comparisons is using an if/else block, like so: if (lc ref($params{whatever}) eq 'regexp') { #use =~ } else { #use eq } Is there a shorter way of doing it? Because of reasons beyond my control I'm using Perl 5.8.8 so I can't use the smart match operator. TIA
