• Latitude & longitude coordinates of Australian states/territories for database using Google Maps

  - by RMW

  Hi, We have a database which has location-based search using Google Maps API. However searching by state or territory in Australia is problematic because Google Maps locates these at the centre of the states and most population centres in Australia are on the coast. We need to hand code in the latitudes and longitudes so that when someone searches for the state 'NSW', for example, the database returns relevant results. Does anyone know where to find a list of the coordinates for the boundaries of Australian states & territories to code into the database? This will save our busy programmer a lot of time. Thanks in advance.

• C++ coverage tool that WORKS?!

  - by Poni

  Been searching for a good coverage tool for a while now. I'm with VC++ 2008. Tried already: NCover, PureCoverage, PartCover and a few others I can't remember their names. None works! Not even with a very basic console application that does almost nothing. Tried to get an evaluation copy from BullsEye and few more others - not only that they require you to ask for it (no automatic process), they don't even answer after you request AND after you ask what's going on, through the support mail. So the question is: Is there any tool, which I can immediately download an evaluation for it, that actually works on VC 2008 projects? Something that will get me going within 10 minutes? It's funny but it seems to be a very non-trivial request in the area of this kind of software.

• Remove anchor from URL in C#

  - by kcoppock

  I'm trying to pull in an src value from an XML document, and in one that I'm testing it with, the src is: <content src="content/Orwell - 1984 - 0451524934_split_2.html#calibre_chapter_2"/> That creates a problem when trying to open the file. I'm not sure what that #(stuff) suffix is called, so I had no luck searching for an answer. I'd just like a simple way to remove it if possible. I suppose I could write a function to search for a # and remove anything after, but that would break if the filename contained a # symbol (or can a file even have that symbol?) Thanks!

• How do you optimize database performance when providing results for autocomplete/iterative search?

  - by Howiecamp

  Note: In this question I'm using the term "autocomplete" (or "iterative search") to refer to returning search-as-you-type results, e.g. like Google Search gives you. Also my question is not specific to web applications vs. fat client apps. How are SQL SELECT queries normally constructed to provide decent performance for this type of query, especially over arbitrarily large data sets? In the case where the search will only query based on the first n characters (easiest case) am I still issuing a new SELECT result FROM sometable WHERE entry LIKE... on each keypress. Even with various forms of caching this seems like it might result in poor performance. In cases where you want your search string to return results with prefix matches, substring matches, etc. it's an even more difficult problem. Looking at a case of searching a list of contacts, you might return results that match FirstName + LastName, LastName + FirstName, or any other substring.

• How does the dispatch action call work in the Twitter sidebar

  - by phwd

  I would like to understand how the call for replies works as follows: <a href="http://twitter.com/replies" data="{"dispatch_action":"replies"}"> <span>@phwd</span> </a> This was taken from the homepage of Twitter. The section in particular being: data="{"dispatch_action":"replies"}" I believe (think), it is using Twitter's own twitter.js script and I do not want to interfere(or copy) with their code, I rather just want to know how the call works. My current setup is using Abraham's twitteroauth PHP library, jQuery and some Ajax to refresh the portion of the page needed using the following method : Use jQuery and PHP to build an Ajax-driven Web page [IBM link - I am a new user so I can only post one link] I apologize if this question is not formatted/worded well, it is my first time. Also I tried searching DocType and StackOverFlow. The Related Questions show me Struts but I am not sure it is that.

• Is there a browser independet bookmarktool supporting tags, date and free comments?

  - by bernd_k

  I am looking for a tool, which helps me to organize my personal bookmarks. I want to be able to assign tags and free comments to a bookmark. I want to search my bookmarks by tags date of bookmarking pattern in title pattern in url It would be nice to be web based to enable sharing my bookmarks between different machines. But for it would be OK, if it works on a single machine as long as it has some import/export way to transfer the links to a new machine replacing the old. As browsers I'm using Firefox and ChromePlus. It would be nice, if the solution works with both browsers. With free comments, I mean additional remarks stored for a bookmark, which is not essential for searching.

• Reading in data from a file into an array

  - by Sam

  If I have an options file along the lines of this: size = 4 data = 1100010100110010 And I have a 2d size * size array that I want to populate the values in data into, what's the best way of doing it? To clarify, for the example I have I'd want an array like this: int[4][4] array = {{1,1,0,0}, {0,1,0,1}, {0,0,1,1}, {0,0,1,0}}. (Not real code but you get the idea). Size can be really be any number though. I'm thinking I'd have to read in the size, maloc an array and then maybe read in a string full of data then loop through each char in the data, cast it to an int and stick it in the appropriate index? But I really have no idea how to go about it, have been searching for a while with no luck. Any help would be cool! :)

• Return segmented average from SQL Query?

  - by Guillaume Filion

  Hi, I measure the load on DNS servers every minute and store that into an SQL DB. I want to draw a chart of the load for the last 48 hours. That's 69120 (48*24*60) data points but my chart's only 800 pixels wide so to make things faster I would like my SQL query to return only ~800 data points. It's seems to me like a pretty standard thing to do, but I've been searching the web and in books for such a thing for a while now and the closest I was able to find was a rolling average. What I'm looking for a more of a "segmented average": divide the 69120 data points in ~800 segments, then average each segment. My SQL table is: CREATE TABLE measurements ( ip int, measurement_time int, queries int, query_time float ) My query looks like this SELECT ip, queries FROM measurements WHERE measurement_time>(time()-172800) Thanks a lot!

• How do I parse a templated string in Python?

  - by mLewisLogic

  I'm new to Python, so I'm not sure exactly what this operation is called, hence I'm having a hard time searching for information in it. Basically I'd like to have a string such as: "[[size]] widget that [[verb]] [[noun]]" Where size, verb, and noun are each a list. I'd like to interpret the string as a metalanguage, such that I can make lots of sentences out permutations from the lists. As a metalanguage, I'd also be able to make other strings that use those pre-defined lists to generate more permutations. Are there any capabilities for variable substitution like this in Python? What term describes this operation if I should just Google it?

• Should I separate RESTful API controllers from "regular" controllers?

  - by keithjgrant

  This seems like an elementary question, but after a lot of searching around I can't seem to find a straightforward explanation: If I'm building a web application that is going to be accessed largely through a web browser, but that will also support some API requests in a RESTful way, should there be a large degree of separation between the two? On one hand, it seems a large amount of the functionality is the same, with identical data presented in different views (HTML vs. XML/JSON). But on the other hand, there are certain things I need to present to the browser that doesn't quite fit a RESTful approach: how to get an empty form to create a new instance of a resource and how to get a pre-populated form to edit an existing resource. Should these two different methods of accessing the system by funneled through different controllers? Different methods in the same controller? The exact same methods with a switch for view type?

• Populating a WPF listbox with items from an SQL (SDF) database

  - by xplinux557

  I have been searching on how to do this for a very long time, and I have not managed to get a straight answer on the subject, so hopefully one of you StackOverflow users will be able to help me here. I have a WPF ListBox named CategoryList and a SDF database called ProgramsList.sdf (with two tables called CategoryList and ProgramsList). What I wish my program to do is get the category names from the CategoryList table and list them in the ListBox control called CategoryList. Here's the code that I tried, but it only caused my program to crash. SqlConnection myConnection = new SqlConnection("Data Source=" + AppDomain.CurrentDomain.BaseDirectory + "ProgramsList.sdf"); SqlDataReader myReader = null; myConnection.Open(); CategoryList.Items.Clear(); SqlDataReader dr = new SqlCommand("SELECT Name FROM CategoryList ORDER BY Name DESC", myConnection).ExecuteReader(); while (myReader.Read()) { CategoryList.Items.Add(dr.GetInt32(0)); } myConnection.Close(); Can anyone help me? Thanks in advance!

• OpenCL support on Leopard

  - by koan

  I want to use OpenCL in my software but I am running Leopard. I will probably update to Snow Leopard later. In the mean time I would like to get started with OpenCL in Leopard. Setting up on 10.5 is confusing: most SDKs and articles assume that you must be using Snow Leopard. Searching for "Using OpenCL on Leopard" is completely useless, as you would expect. I downloaded the cuda toolkit, devdriver and gpucomputing SDK from nvidia but the examples won't compile because OpenCL/opencl.h is not found. The OpenCL release notes don't mention MacOSX so again I think this is assuming that all Mac users are running Snow Leopard. Where can I find OpenCL includes and libraries for Mac OSX 10.5 ? Or, is this just a waste of time and I should go and get Snow Leopard ASAP ? After upgrading to Snow Leopard I would like my software to support Leopard. Is this possible ?

• Libraries for making a voice chat application

  - by Eric

  My development team is going to build a voice chat application. Our plan is to use a pre-made library just for this purpose, but we haven't found any good one after days of searching the internet, so I thought I would consider a question here! So the question is: What library / project do you recommend? We are deadly serious with this, so it needs to be a good working one. Preferable an open-source one as well. We have been looking at some XMPP libraries and projects, but none seems to be up-to-date, tested and well-documented.

• Index for wildcard match of end of string

  - by Anders Abel

  I have a table of phone numbers, storing the phone number as varchar(20). I have a requirement to implement searching of both entire numbers, but also on only the last part of the number, so a typical query will be: SELECT * FROM PhoneNumbers WHERE Number LIKE '%1234' How can I put an index on the Number column to make those searchs efficient? Is there a way to create an index that sorts the records on the reversed string? Another option might be to reverse the numbers before storing them, which will give queries like: SELECT * FROM PhoneNumbers WHERE ReverseNumber LIKE '4321%' However that will require all users of the database to always reverse the string. It might be solved by storing both the normal and reversed number and having the reversed number being updated by a trigger on insert/update. But that kind of solution is not very elegant. Any other suggestions?

• MessageBox.Show not raising HelpRequested event

  - by Trevortni

  I have a form that is showing a MessageBox using MessageBox.Show, and trying to receive events from the Help button on the MessageBox so I can execute my own code. The Microsoft documentation shows how to do this; however, using what is suggested does not work. Here's a shortened version of my code: Private Function MethodName() As Boolean AddHandler Me.HelpRequested, AddressOf Me.MsgBoxHelpRequested Select Case MessageBox.Show("Text", "Title", MessageButtons.YesNoCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2, 0, True) Case MsgBoxResult.Yes ' Do stuff Case MsgBoxResult.No ' Do stuff Case MsgBoxResult.Cancel RemoveHandler Me.HelpRequested, AddressOf Me.MsgBoxHelpRequested Return False End Select RemoveHandler Me.HelpRequested, AddressOf Me.MsgBoxHelpRequested End Function Private Sub MsgBoxHelpRequested(ByVal sender As Object, ByVal hlpevent As System.Windows.Forms.HelpEventArgs) ' Breakpoint that never gets hit ' More code End Sub I've been searching for a solution to this problem, but the best I've found is this question: http://stackoverflow.com/questions/2407880/how-to-detect-help-button-press-in-windows-forms-messagebox that refers me back to the same Microsoft code that doesn't seem to be working. Can anybody help me with this? Thank you.

• Database Engine not appearing in SQL Server listing

  - by Jonn

  I don't know if I'm searching for the wrong queries in google but I can't seem to find an answer to this. I have SQL Server 2008 installed in my pc and according to services.msc, I've got 2 database engines running: SQLEXPRESS (probably one that came along with Visual Studio) and MSSQLSERVER. When I try to connect only SQLEXPRESS is visible in the Server Name drop down list. I tried to explicitly state MSSQLSERVER by typing in MYPCNAME\MSSQLSERVER Didn't work. The best solution I could find in the internet was to enable stuff at Configuration Manager. Didn't work either (although I did find that TCP/VIA and all other options were disabled for MSSQLSERVER). Anyone have any other ideas on what I should try next or probably something that I overlooked?

• Flash Media Server dynamic file naming

  - by flying_tiger

  I'm trying to figure out most efficient/safe way to name recorded streams on FMS. The case is to get listing of recorded streams from the server (eg. rec_001, rec_002...) and dynamically add rec_003 filename to the new stream that is being recorded. I'm thinking about either using FMS File Object and put everything in array of files every time I start recording procedure or to create XML file that would serve as a database of file names. I'm searching for a solution efficient for MULTIPLE connections at a time and large amount of files. Which one of presented would be the best for this purpose? Or do you have any better suggestions of solving this problem?

• database row/ record pointers

  - by David

  Hi I don't know the correct words for what I'm trying to find out about and as such having a hard time googling. I want to know whether its possible with databases (technology independent but would be interested to hear whether its possible with Oracle, MySQL and Postgres) to point to specific rows instead of executing my query again. So I might initially execute a query find some rows of interest and then wish to avoid searching for them again by having a list of pointers or some other metadata which indicates the location on a database which I can go to straight away the next time I want those results. I realise there is caching on databases, but I want to keep these "pointers" else where and as such caching doesn't ultimately solve this problem. Is this just an index and I store the index and look up by this? most of my current tables don't have indexes and I don't want the speed decrease that sometimes comes with indexes. So whats the magic term I've been trying to put into google? Cheers

• Begin Viewing Query Results Before Query Ends

  - by Frank Developer

  OK, so say I have a table with 500K rows, then I ad-hoc query with unsupported indexing which requires a full table scan. I would like to immediately view the first rows returned while the full table scan continues. Then I want to scroll thru the next results. In the meantime, I would like to display the progress of the table scan, example: "SEARCHING.. FOUND 23 OF 500,000 ROWS SO FAR". If I scroll too far ahead, I want to display a message like: "REACHED LAST ROW IN LOOK-AHEAD BUFFER.. QUERY HAS NOT COMPLETED".. Can this be done? Maybe like: spawn/exec, declare scroll cursor, open, fetch, etc.?

• Issues with dynamically allocating a string array

  - by Jason Block

  Brand new to C. I am trying to dynamically allocate the array frags2 of size numberOfFrags and copy over the contents of the original array to it. I have tried numerous approaches and searching and do not understand what is going wrong here. Sizeof on the new array returns 0 instead of what I thought I malloc'd. Any help would be much appreciated! int main(int argc, const char* argv[]) { char* frags[MAX_FRAG_COUNT]; FILE* fp = fopen(argv[1], "r"); int numberOfFrags = ReadAllFragments(fp, frags, MAX_FRAG_COUNT); fclose(fp); char** frags2 = (char**)malloc(numberOfFrags * sizeof(char*)); for (int i = 0; i < numberOfFrags; i++) { frags2[i] = frags[i]; } qsort(frags2, sizeof(frags2) / sizeof(char *), sizeof(char*), cstring_cmp);

• MySQL indexes - what are the best practises?

  - by Haroldo

  I've been using indexes on my mysql databases for a while now but never properly learnt about them. Generally I put an index on any fields that i will be searching or selecting using a WHERE clause but sometimes it doesn't seem so black and white. What are the best practises for mysql indexes? example situations/dilemas: If a table has six columns and all of them are searchable, should i index all of them or none of them? . What are the negetive performance impacts of indexing? . If i have a VARCHAR 2500 column which is searchable from parts of my site, should i index it?

• Location of MFT file?

  - by baltusaj

  I have a partition, formatted as NTFS. I have studied that devices formatted as NTFS have a MFT (Master File Table) which contains a lot of information about the contents of a devices. Is MFT really a file? Where is it located? How can I view it? I, actually want to view the $BITMAP to know the locations of all the files and directories in a partition. Update: Seems like I can only view the MFT file using HexEditor. Still searching for more options though...

• Using an observer within an Engine

  - by Tim

  I've created an Engine which is basically used for all of our projects. Now what I want to do is add a before_create callback to all of the models in this Engine. After some searching I found out that an observer is the way to go. So, I've created this observer: class AuthObserver < ActiveRecord::Observer def before_create( record ) p record end end And now I need to add it to the application, but of course in my Engine there is no such file as application.rb. What I tried is adding it to an initializer located in /config/initializers/observers.rb Like so: Rails.application.config.active_record.observers = :auth_observer But this doesn't work, and it throws no errors. Anybody out here has experience using an observer inside an engine? Thanks a lot!
