• Expression Studio 4 Premium & SketchFlow question; WTH

  - by Refracted Paladin

  Through work I have an Visual Studio Premium with MSDN subscription that I love. However, my biggest disappointment of the last 12 months was discovering that our 2nd from the top level subscription was not enough to get me Sketchflow! This is, most decidedly, NOT SHINY, and I am borderline distraught! What are my options? Upgrading to an Ultimate subscription for Sketchflow is out of the question. Am I forced, then, to stay with Blend 3 or Purchase Blend 4 seperately? If this is not a question I should ask here please inform and I'll delete. I just tend to default to SO for all questions that Google can't answer and Google did not answer this one.

• How to get unique URL identifier after inserting item in Google Base with Zend Gdata API?

  - by msumme

  I need to get the unique URL identifier for the product that is created after inserting an item into Google Base using the Zend_Gdata_Gbase library. I can't seem to do this. I am finding a startling lack of documentation online about manipulating the objects used in these applications. The url that I add to the object does not work to retrieve the base item later, which is why I need to get the one that google generates upon submission. I am writing a program that will need to be able to delete content at a later date, and thus will need to store that information in order to keep the website synced with the Google Base feed. Thanks in advance for any help.

• Java - JDBC alternatives

  - by Mike

  Hello, this is just teorethical question. I use JDBC with my Java applications for using database (select, insert, update, delete or whatever). I make "manually" Java classes which will contain data from DB tables (attribute = db column). Than I make querys (ResultSet) and fill those classes with data. I am not sure, if this is the right way. But I've read lot of about JDO and another persistence solutions. Can you please recommend some? Which are modern? Will be used in the future? Some advantages of JDO over JDBC (in simple words). I've been able to google lot of this stuff, but opinions from the "first hand" are always best. Thank you for responses, Mike

• How to replace master branch in git, entirely, from another branch?

  - by Jason

  Hi, I have two branch in my git repo: master seotweaks (created originally from master) I created "seotweaks" with the intention of quickly merging it back into master, however that was 3 months ago and the code in this branch is 13 versions ahead of "master", it has effectively become our working master branch as all the code in "master" is more or less obsolete now. Very bad practice I know, lesson learnt. Do you know how I can replace all of the contents of the "master" branch with those in "seotweaks"? I could just delete everything in "master" and merge, but this does not feel like best practice.

• Append a parent element to arrays in PHP for a foreach loop

  - by Erik Berger

  print_r of $data = json_decode($src, true); returns data that looks like this: Array ( [0] => Array ( [var1] => blah [var2] => foo ) [1] => Array ( [var1] => lorem [var2] => ipsum ) // goes down to [1936] ) I want to build an html table that shows var1 and var2 next to each other in the same row. I know do to this I need a foreach statement like foreach($data['items'] as $item) but the problem I think I am having is that my many arrays aren't the child of one thing like 'items', right? I looked into array_push but couldn't figure it out. Can someone help my orphaned parentless arrays?

• Removing a node from a linked list

  - by lost_with_coding

  I would like to create a delete_node function that deletes the node at the location in the list as a count from the first node. So far this is the code I have: class node: def __init__(self): self.data = None # contains the data self.next = None # contains the reference to the next node class linked_list: def __init__(self): self.cur_node = None def add_node(self, data): new_node = node() # create a new node new_node.data = data new_node.next = self.cur_node # link the new node to the 'previous' node. self.cur_node = new_node # set the current node to the new one. def list_print(self): node = ll.cur_node while node: print node.data node = node.next def delete_node(self,location): node = ll.cur_node count = 0 while count != location: node = node.next count+=1 delete node ll = linked_list() ll.add_node(1) ll.add_node(2) ll.add_node(3) ll.list_print()

• Automated Java to Scala source code conversion?

  - by Alex R

  (Yes I know I can call Java code from Scala; but that is pointless; I want to DELETE the Java code, not keep it around and have to look at it and maintain it forever!) Are there any utilities out there to convert Java source to Scala source? I believe theoretically it should be possible to accomplish with minimal lossage. I have found this but it seems inactive, probably buggy/incomplete... http://sourceforge.net/projects/java2scala/ Any alternatives?

• Creating a new coloumn for date info with specific date format

  - by Ayan

  Dear All I am working with a file which has few years data and I am trying to create an aditional coloumn that reads the year and month info from the date coloumn (e.g. 01/01/1997 12:00) and create a new coloumn with month and year together(e.g. Jan-97). I am not sure how to proceed with this but what I am trying to code is the coloumn with name "new_date" in the following picture: my sample data = > dput(df) structure(list(date = structure(c(1L, 4L, 7L, 2L, 5L, 8L, 3L, 6L, 9L), .Label = c("01/01/1997 12:00", "01/01/1998 15:00", "01/01/1999 18:00", "01/02/1997 13:00", "01/02/1998 16:00", "01/02/1999 19:00", "01/03/1997 14:00", "01/03/1998 17:00", "01/03/1999 19:00"), class = "factor"), value = c(29L, 31L, 42L, 42L, 52L, 61L, 57L, 55L, 56L)), .Names = c("date", "value"), row.names = c(NA, -9L), class = "data.frame") I would really appreciate if you could advise me about how should I proceed with this, Many thanks, Ayan

• How Implement a system to determine if a milestone has been reached

  - by Luc M

  I have a table named stats player_id team_id match_date goal assist` 1 8 2010-01-01 1 1 1 8 2010-01-01 2 0 1 9 2010-01-01 0 5 ... I would like to know when a player reach a milestone (eg 100 goals, 100 assists, 500 goals...) I would like to know also when a team reach a milestone. I want to know which player or team reach 100 goals first, second, third... I thought to use triggers with tables to accumulate the totals. Table player_accumulator (and team_accumulator) table would be player_id total_goals total_assists 1 3 6 team_id total_goals total_assists 8 3 1 9 0 5 Each time a row is inserted in stats table, a trigger will insert/update player_accumulator and team_accumulator tables. This trigger could also verify if player or team has reached a milestone in milestone table containing numbers milestone 100 500 1000 ... A table player_milestone would contains milestone reached by player: player_id stat milestone date 1 goal 100 2013-04-02 1 assist 100 2012-11-19 There is a better way to implements a "milestone" ? There is an easiest way without triggers ? I'm using PostgreSQL

• Dynamically register constructor methods in an AbstractFactory at compile time using C++ templates

  - by Horacio

  When implementing a MessageFactory class to instatiate Message objects I used something like: class MessageFactory { public: static Message *create(int type) { switch(type) { case PING_MSG: return new PingMessage(); case PONG_MSG: return new PongMessage(); .... } } This works ok but every time I add a new message I have to add a new XXX_MSG and modify the switch statement. After some research I found a way to dynamically update the MessageFactory at compile time so I can add as many messages as I want without need to modify the MessageFactory itself. This allows for cleaner and easier to maintain code as I do not need to modify three different places to add/remove message classes: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <inttypes.h> class Message { protected: inline Message() {}; public: inline virtual ~Message() { } inline int getMessageType() const { return m_type; } virtual void say() = 0; protected: uint16_t m_type; }; template<int TYPE, typename IMPL> class MessageTmpl: public Message { enum { _MESSAGE_ID = TYPE }; public: static Message* Create() { return new IMPL(); } static const uint16_t MESSAGE_ID; // for registration protected: MessageTmpl() { m_type = MESSAGE_ID; } //use parameter to instanciate template }; typedef Message* (*t_pfFactory)(); class MessageFactory· { public: static uint16_t Register(uint16_t msgid, t_pfFactory factoryMethod) { printf("Registering constructor for msg id %d\n", msgid); m_List[msgid] = factoryMethod; return msgid; } static Message *Create(uint16_t msgid) { return m_List[msgid](); } static t_pfFactory m_List[65536]; }; template <int TYPE, typename IMPL> const uint16_t MessageTmpl<TYPE, IMPL >::MESSAGE_ID = MessageFactory::Register( MessageTmpl<TYPE, IMPL >::_MESSAGE_ID, &MessageTmpl<TYPE, IMPL >::Create); class PingMessage: public MessageTmpl < 10, PingMessage > {· public: PingMessage() {} virtual void say() { printf("Ping\n"); } }; class PongMessage: public MessageTmpl < 11, PongMessage > {· public: PongMessage() {} virtual void say() { printf("Pong\n"); } }; t_pfFactory MessageFactory::m_List[65536]; int main(int argc, char **argv) { Message *msg1; Message *msg2; msg1 = MessageFactory::Create(10); msg1->say(); msg2 = MessageFactory::Create(11); msg2->say(); delete msg1; delete msg2; return 0; } The template here does the magic by registering into the MessageFactory class, all new Message classes (e.g. PingMessage and PongMessage) that subclass from MessageTmpl. This works great and simplifies code maintenance but I still have some questions about this technique: Is this a known technique/pattern? what is the name? I want to search more info about it. I want to make the array for storing new constructors MessageFactory::m_List[65536] a std::map but doing so causes the program to segfault even before reaching main(). Creating an array of 65536 elements is overkill but I have not found a way to make this a dynamic container. For all message classes that are subclasses of MessageTmpl I have to implement the constructor. If not it won't register in the MessageFactory. For example commenting the constructor of the PongMessage: class PongMessage: public MessageTmpl < 11, PongMessage > { public: //PongMessage() {} /* HERE */ virtual void say() { printf("Pong\n"); } }; would result in the PongMessage class not being registered by the MessageFactory and the program would segfault in the MessageFactory::Create(11) line. The question is why the class won't register? Having to add the empty implementation of the 100+ messages I need feels inefficient and unnecessary.

• Return database messages on successful SQL execution when using ADO

  - by peacedog

  I'm working on a legacy VB6 app here at work, and it has been a long time since I've looked at VB6 or ADO. One thing the app does is to executes SQL Tasks and then to output the success/failure into an XML file. If there is an error it inserts the text the task node. What I have been asked to do is try and do the same with the other mundane messages that result from succesfully executed tasks, like (323 row(s) affected). There is no command object being used, it's just an ADODB.Connection object. Here is the gist of the code: Dim sqlStatement As String Set sqlStatement = /* sql for task */ Dim sqlConn As ADODB.Connection Set sqlConn = /* connection magic */ sqlConn.Execute sqlStatement, , adExecuteNoRecords What is the best way for me to capture the non-error messages so I can output them? Or is it even possible?

• Most Efficient Alternative Method of Storing Settings for iPhone Apps

  - by JPK

  I am not using the Settings bundle to store the settings for my app, as I prefer to allow the user to access the settings within the app (they may be changed fairly often). I do realize that there is the option to do both, but for now, I am trying to find the most optimal place to store the settings within the app. I have a good number of settings (from what I have read, probably too many for NSUserDefaults), and the two main options I am considering are: 1) storing the settings in a dictionary in the plist, loading the settings into a NSDictionary property in the app delegate and accessing them via the sharedDelegate 2) storing the settings in a Core Data entity (1 row on Settings entity), loading the settings into a Settings object in the app delegate and accessing them via the sharedDelegate Of these two, which would be the optimal method, performance wise?

• Speeding up jQuery empty() or replaceWith() Functions When Dealing with Large DOM Elements

  - by Levi Hackwith

  Let me start off by apologizing for not giving a code snippet. The project I'm working on is proprietary and I'm afraid I can't show exactly what I'm working on. However, I'll do my best to be descriptive. Here's a breakdown of what goes on in my application: User clicks a button Server retrieves a list of images in the form of a data-table Each row in the table contains 8 data-cells that in turn each contain one hyperlink Each request by the user can contain up to 50 rows (I can change this number if need be) That means the table contains upwards of 800 individual DOM elements My analysis shows that jQuery("#dataTable").empty() and jQuery("#dataTable).replaceWith(tableCloneObject) take up 97% of my overall processing time and take on average 4 - 6 seconds to complete. I'm looking for a way to speed up either of the above mentioned jQuery functions when dealing with massive DOM elements that need to be removed / replaced. I hope my explanation helps.

I have the clicked item saved in the variable 'clicked'. If possible I'd like to delete the link around the image also.

• declaring constraint to consider prog logic

  - by shantanuo

  I can open a trip only once but can close it multiple times. I can not declare the Trip_no + status as primary key since there can be multiple entries while closing the trip. Is there any way that will assure me that a trip number is opened only once? For e.g. there should not be the second row with "Open" status for trip No. 3 since it is already there in the following table. Trip No | Status 1 Open 1 Close 1 Close 2 Open 2 Close 3 Open 3 Close 3 Close 3 Close 3 Close

• C++ Allocate Memory Without Activating Constructors

  - by schnozzinkobenstein

  I'm reading in values from a file which I will store in memory as I read them in. I've read on here that the correct way to handle memory location in C++ is to always use new/delete, but if I do: DataType* foo = new DataType[sizeof(DataType) * numDataTypes]; Then that's going to call the default constructor for each instance created, and I don't want that. I was going to do this: DataType* foo; char* tempBuffer=new char[sizeof(DataType) * numDataTypes]; foo=(DataType*) tempBuffer; But I figured that would be something poo-poo'd for some kind of type-unsafeness. So what should I do? And in researching for this question now I've seen that some people are saying arrays are bad and vectors are good. I was trying to use arrays more because I thought I was being a bad boy by filling my programs with (what I thought were) slower vectors. What should I be using???

• Git push works for gitosis but not my own repo (Permission denied)

  - by Mickey Cheong

  Hi, I follow this exact guide to setup my GIT server: http://blog.agdunn.net/?p=277 I tried it before and it works. However, this time, when I provision a new server, it doesn't. I followed the exact steps and I provision it 3 times. It still failed. I get this errors: Permission denied (publickey). fatal: The remote end hung up unexpectedly However, this only happen when I try to add a remote origin and push my new repo. If I do a git push on my gitosis, it works perfectly fine. I tried look into the IP and all the permission, I can't figure out what went wrong. Another test I did was, I went into .ssh/known_hosts/ and delete the IP entry. When I tried to do a git push for gitosis-admin, it will prompt if I wanted to allow this IP. However, this prompt doesn't appear for my new repo. Any help will be great appreciated. Thanks, Mickey

• Rails ActiveRecord: Find All Users Except Current User

  - by SingleShot

  I feel this should be very simple but my brain is short-circuiting on it. If I have an object representing the current user, and want to query for all users except the current user, how can I do this, taking into account that the current user can sometimes be nil? This is what I am doing right now: def index @users = User.all @users.delete current_user end What I don't like is that I am doing post-processing on the query result. Besides feeling a little wrong, I don't think this will work nicely if I convert the query over to be run with will_paginate. Any suggestions for how to do this with a query? Thanks.

• Singleton array deallocated? EXC_BAD_ACCESS

  - by lclaud

  Ok, so I have this singleton object and in it is an array that needs to be shown in a tableview. The thing is that it deallocates and after the first show, i get EXC_BAD_ACCESS in cellForRowAtIndexPath - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [[dataBase shareddataBase].dateActive count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"celula"]; int i; i=indexPath.row; if (cell==nil) { cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:@"celula"]; } count sent to dealocated instance of CFArray .. in cellForRowAtIndexPath.. WHAT is deallocating it? why? it's declarea as an NSMutableArray and has a (nonatomic,retain) property defined .. if ((i<[[dataBase shareddataBase].dateActive count])&&(i>=0)) { NSDictionary *d=[[dataBase shareddataBase].dateActive objectAtIndex:i]; cell.textLabel.text=[d objectForKey:@"detaliu"]; } return cell; }

• SQL Server union selects built dynamically from list of words

  - by Adam Tuttle

  I need to count occurrence of a list of words across all records in a given table. If I only had 1 word, I could do this: select count(id) as NumRecs where essay like '%word%' But my list could be hundreds or thousands of words, and I don't want to create hundreds or thousands of sql requests serially; that seems silly. I had a thought that I might be able to create a stored procedure that would accept a comma-delimited list of words, and for each word, it would run the above query, and then union them all together, and return one huge dataset. (Sounds reasonable, right? But I'm not sure where to start with that approach...) Short of some weird thing with union, I might try to do something with a temp table -- inserting a row for each word and record count, and then returning select * from that temp table. If it's possible with a union, how? And does one approach have advantages (performance or otherwise) over the other?

• Is a class that is hard to unit test badly designed?

  - by Extrakun

  I am now doing unit testing on an application which was written over the year, before I started to do unit-testing diligently. I realized that the classes I wrote are hard to unit test, for the following reasons: Relies on loading data from database. Which means I have to setup a row in the table just to run the unit test (and I am not testing database capabilities). Requires a lot of other external classes just to get the class I am testing to its initial state. On the whole, there don't seem to be anything wrong with the design except that it is too tightly coupled (which by itself is a bad thing). I figure that if I have written automated test cases with each of the class, hence ensuring that I don't heap extra dependencies or coupling for the class to work, the class might be better designed. Does this reason holds water? What are your experiences?

• Which PHP session settings are incorrect here?

  - by Greg McNulty

  I see the savepath has no value but does it default to something? Are the other values OK? I have access to the server and PHP files but how and what do I change? The specific issue - On page 1: session_start(); $_SESSION['uType']=$row['usertype']; //save user type to session print_r($_SESSION); //Prints the user type successfully On page 2: session_start(); print_r($_SESSION); //BLANK?? Observed: Page 1 displays the session data. However, there are NO cookies created anywhere on the browser? Page 1 does a require to display page 2. Page 2 does not contain the session data. Using FireFox as the target browser (looking at cookies with web developer add-in) How do I get the session to work across all pages? Thank You and yes I am a newbie at this.

• Copying Some from a PostgreSQL Server to Another

  - by whollychao

  I am in need of an application that can periodically transmit select rows from a PostgreSQL database across a network to a second PostgreSQL server. Typically these will be the most recent row added, pulled and transmitted every 10-30 seconds. The primary servers run in a MS Windows environment with a high-latency, and occasionally intermittent, network connection. Therefore, any application would have to be tolerant of this and ideally automatically reconnect / resend data that could not be transmitted. Due to the environment and the requirements, a full-blown replication package would be unnecessary. I appreciate any help anyone has with this problem.

• Referencing a control inside a XSL Template from code behind ?

  - by Mina Samy

  Hi all I have a custom NewItem.aspx that I made by creating a new aspx from the exisiting one I wanted to put a control in a row inside the XSL Template like this <asp:DropDownList ID="ddlSectors" AutoPostBack="true" runat="server" __designer:bind="{ddwrt:DataBind('i',ddlSectors,'SelectedValue','TextChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Sector')}"> </asp:DropDownList> <!--<SharePoint:FormField runat="server" id="ff7{$Pos}" ControlMode="New" FieldName="Sector" __designer:bind="{ddwrt:DataBind('i',concat('ff7',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Sector')}"/>--> <SharePoint:FieldDescription runat="server" id="ff7description{$Pos}" FieldName="Sector" ControlMode="New"/> Now I want to reference ddlSectors from my code library but it always throws an object reference not set to an instatnce of an object. I believe that this is becuase the control is inside the XSL template. so is there any workaround for this ? thanks
