• Probability algorithm: Finding probable correct item in a list (e.g John, John, Jon)

  - by Andrew White

  Hi, Take for example the list (L): John, John, John, John, Jon We are to presume one item is to be correct (e.g. John in this case), and give a probability it is correct. First (and good!) attempt: MostFrequentItem(L).Count / L.Count (e.g. 4/5 or 80% likelihood) But consider the cases: John, John, Jon, Jonny John, John, Jon, Jon I want to consider the likelihood of the correct item being John to be higher in the first list! I know I have to count the SecondMostFrequent Item and compare them. Any ideas? This is really busting my brain! Thx, Andrew

• System.Uri can't parse when password field contains a "#"

  - by Andrew

  The following code throws System.UriFormatException: var uri = new UriBuilder("ftp://user:pass#[email protected]:21/fu/bar.zip"); System.UriFormatException: Invalid URI: A port was expected because of there is a colon (':') present but the port could not be parsed. Removing the # symbol from the password field solves the issue. Is a # symbol a valid character to have in the password field? Is there a way to escape this? Is this a known bug in the parsing routine of the Uri class? How does one get around this - assuming you can't change the password? ;-) Thanks, Andrew

• How to avoid OLEDB converting "."s into "#"s in column names?

  - by Andrew Miner

  I'm using the ACE OLEDB driver to read from an Excel 2007 spreadsheet, and I'm finding that any '.' character in column names get converted to a '#' character. For example, if I have the following in a spreadsheet: Name Amt. Due Due Date Andrew 12.50 4/1/2010 Brian 20.00 4/12/2010 Charlie 1000.00 6/30/2010 the name of the second column would be reported as "Amt# Due" when read with the following code: OleDbConnection connection = new OleDbConnection( "Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; " + "Extended Properties=\"Excel 12.0 Xml;HDR=YES;FMT=Delimited;IMEX=1\""); OldDbCommand command = new OleDbCommand("SELECT * FROM MyTable", connection); OleDbReader dataReader = command.ExecuteReader(); System.Console.WriteLine(dataReader.GetName(1)); I've read through all the documentation I can find and I haven't found anything which even mentions that this will happen. Has anyone run into this before? Is there a way to fix this behavior?

• IE9 syntax on jquery crossbrowser with jsonp and FF, Chrome

  - by Andrew Walker

  I have the following code and i have a problem in ensuring part of it is used when a IE browser is used, and remove it when any other browser is used: $.ajax({ url: 'http://mapit.mysociety.org/areas/'+ulo, type: 'GET', cache: false, crossDomain: true, dataType: 'jsonp', success: function(response) { This works fine in IE9 because I have put the dataType as jsonp. But this will not work on Chrome or FF. So I need to remove the dataType. I tried this: <!--[IF IE]> dataType: 'jsonp', <![endif]--> But it did not work. It's worth noting, it does not need the dataType set when in FF or Chrome as it's json. Whats the correct syntax to have this work ? Thanks Andrew

• Focus In An ItemsControl

  - by Andrew

  I have an ItemsControl that uses a DataTemplate. The DataTemplate contains a TextBox, which can receive keyboard focus. I need to be able to move the keyboard focus from the currently focused TextBox in the DataTemplate to the next TextBox, as if the Tab key has been pressed. I've noticed that there is a UIElement.MoveFocus() method, but this begs the question as to which UIElement should be used to call the method. This is probably the reason why I haven't gotten this method to work for me... Any help would be really appreciated! Thanks, Andrew

• Reusable socket

  - by Andrew

  I tryed to create a socket in php and reuse it from other process. I know this can be done with a daemon script but I want to do this without. I created a socket and binded it to a specific port. $sock = socket_create (AF_INET, SOCK_STREAM, SOL_TCP); socket_set_option ($sock, SOL_SOCKET, SO_REUSEADDR, 1); socket_bind ($sock, 'xx.xx.xx.xx', 10000); socket_connect ($sock, $host, $port); And from another php file I did the same thing. But the packets that I send from the 2 file are not "validated" by host. I sniffed all ports and I see that it uses same local and destination port. I don't understand where is the problem. Can you help me with this? It's ok in any other programming language, or any other solution for this. Andrew

• Get Contact Profile Information from Office Communicator (OCS) SDK in C#?

  - by Andrew

  Hi, My company uses MS Office Communicator Server (OCS) 2007 R2, and I am accessing with C# with the SDK. If I right click on a contact in OCS, I get the option to 'View Contact Card'. I want access to this via the API! Unfortunately I can find nothing in the SDK documentation to get at this. There is a method called 'ViewProfile' which is unsupported, and I can find nothing out there about it. I could of course go directly to the Active Directory account of the contact, but that would require my machine to connect to the organization via VPN. Since most of us work 'offline' I would prefer not to do this. (The data I need is anyway in OCS!) Thanks in advance, Andrew

• Pop-up Window was moved but its image still left behind.

  - by andrew

  Hi, I'm using VS 2005 and .NET framework 2.0 SP2 to build an application with a datagridview in it. I'm using Microsoft Word 11.0 Object Library to do the spelling checker on one of the field in datagridview. When it detected a spelling and grammar window would pop-up open on top of the datagridview. The problem I got was when I moved the pop-up window to the new location, there's still an image of the pop-up window left behind the previous location. The more I moved the more of those copied image would be created on screen. How I can overcome this problem? Thanks in advance, Andrew

• Java dropping half of UDP packets

  - by Andrew Klofas

  Greetings, I have a simple client/server setup. The server is in C and the client that is querying the server is Java. My problem is that, when I send bandwidth-intensive data over the connection, such as Video frames, it drops up to half the packets. I make sure that I properly fragment the udp packets on the server side (udp has a max payload length of 2^16). I verified that the server is sending the packets (printf the result of sendto()). But java doesn't seem to be getting half the data. Furthermore, when I switch to TCP, all the video frames get through but the latency starts to build up, adding several seconds delay after a few seconds of runtime. Is there anything obvious that I'm missing? I just can't seem to figure this out. Thanks, Andrew

• NHibernate's automatic (dirty checking) update behaviour - turning it off

  - by Andrew Bullock

  I've just discovered that if I get an object from an NHibernate session and change a property on object, NHibernate will automatically update the object on commit without me calling Session.Update(myObj)! I can see how this could be helpful, but as default behaviour it seems crazy! How can I stop this happening? Is this default NHib behaviour or something coming from Fluent NHibs AutoPersistenceModel? If there's no way to stop this, what do I do? Unless I'm missing the point this behaviour seems to create a right mess, violating my UoW. Im using NHibernate 2.0.1.4 and a Fluent NHib build from 18/3/2009 Edit, is this guy right with his answer? Edit: I've also read that overriding an Event Listener could be a solution to this. However, IDirtyCheckEventListener.OnDirtyCheck isn't called in this situation. Does anyone know which listener I need to override? Thanks Andrew

• wheel of fortune collision detection

  - by Andrew

  Hey, I have a wheel segmented into 8 pie pieces, and a picker that is pointing at the currently selected segment (think wheel of fortune). I want to highlight the currently selected segment, and so have started to use Chipmunk to construct the 8 segments, attached to a rotating body, and then the picker that is put in a position to collide with each of the segments. The trick is, how do you allow the picker to pass over top of the segments, while still getting the collision, but not actually colliding and slowing down the wheel? I haven't started down this path yet, but thought this may solve the problem: removing the colliding segment and then putting it back after the picker has started colliding with another segment a bit away (like two segments away). There may be a much simpler solution not even involving Chipmunk that I haven't thought of. Thanks, Andrew

• Tips on debugging copy and paste into powerpoint 2010

  - by Andrew S.

  I have a custom application in C++ that has been used to successfully copy-and-paste an object from the application into MS Office 2003 and 2007 (Word, Excel and PowerPoint). The object opens in our own custom activeX control. Now with windows XP and PowerPoint 2010, nothing happens on the cut-and-paste. I have tried turning off the smart copy/paste to no avail. Copy/paste works with Word and Excel 2010. Do you have tips on how to debug this? Thanks Andrew

• filtering for multiple values on one column. All values must exist, else - return zero

  - by Andrew

  Hello All, I would like to filter one column in a table for couple values and show results only if all those values are there. If one or more is missing, then return zero results. example table +----+--------+----------+ | id | Fruit | Color | +----+--------+----------+ | 1 | apple | red | | 2 | mango | yellow | | 3 | banana | yellow | +----+--------+----------+ example "wrong" code: (this must return 3 rows) select Fruit FROM table WHERE Color = red AND Color = yellow but select Fruit FROM table WHERE Color = red AND Color = green must return 0 rows. (If i use select Fruit FROM table WHERE Color = red OR Color = green i get 1 row which is not what i need) I am using PHP with form where user checks different checkboxes that represent different values of the same column. So when he selects multiple checkboxes, all those values should be in the result set, otherwise no result should be given. Thank you, Andrew

• NHibernate Linq queries not returning data saved in the same transaction

  - by Andrew

  Hi, I have a situation where I am using NHibernate in a WCF service and using a TransactionScope for the transaction management. NHibernate enlists in the ambient transaction fine, but, any changes I make and save inside the transaction, are not visible to any queries I make while still in that transaction. So if I add an entity and session.save() it, then further on in the code, there is a linq query against that entities table, the entity I just added is not returned. Strangely this seems to work fine if I use explicit NHibernate transactions in my tests. Anyone have any ideas as to why and what I can do about it? Many thanks Andrew

• C++ simple logging class with UTF-8 output [code example]

  - by Andrew

  Hello everyone, I was working on one of my academic projects and for the first time I needed pure C++ without GUI. After googling for a while, I did not find any simple and easy to use implementation for logging and created my own. This is a simple implementation with iostreams that logs messages to screen and to the file simultaneously. I was thinking of using templates but then I realized that I do not expect any changes and removed that. It is modified std::wostream with two added modifiers: 1. TimeStamp - prints time-stamp 2. LogMode(LogModes) - switches output: file only, screen only, file+screen. *Boost::utf8_codecvt_facet* is used for UTF-8 output. // ############################################################################ // # Name: MyLog.h # // # Purpose: Logging Class Header # // # Author: Andrew Drach # // # Modified by: <somebody> # // # Created: 03/21/10 # // # SVN-ID: $Id$ # // # Copyright: (c) 2010 Andrew Drach # // # Licence: <license> # // ############################################################################ #ifndef INCLUDED_MYLOG_H #define INCLUDED_MYLOG_H // headers -------------------------------------------------------------------- #include <string> #include <iostream> #include <fstream> #include <exception> #include <boost/program_options/detail/utf8_codecvt_facet.hpp> using namespace std; // definitions ---------------------------------------------------------------- // ---------------------------------------------------------------------------- // DblBuf class // Splits up output stream into two // Inspired by http://wordaligned.org/articles/cpp-streambufs // ---------------------------------------------------------------------------- class DblBuf : public wstreambuf { private: // private member declarations DblBuf(); wstreambuf *bf1; wstreambuf *bf2; virtual int_type overflow(int_type ch) { int_type eof = traits_type::eof(); int_type not_eof = !eof; if ( traits_type::eq_int_type(ch,eof) ) return not_eof; else { char_type ch1 = traits_type::to_char_type(ch); int_type r1( bf1on ? bf1->sputc(ch1) : not_eof ); int_type r2( bf2on ? bf2->sputc(ch1) : not_eof ); return (traits_type::eq_int_type(r1,eof) || traits_type::eq_int_type(r2,eof) ) ? eof : ch; } } virtual int sync() { int r1( bf1on ? bf1->pubsync() : NULL ); int r2( bf2on ? bf2->pubsync() : NULL ); return (r1 == 0 && r2 == 0) ? 0 : -1; } public: // public member declarations explicit DblBuf(wstreambuf *bf1, wstreambuf *bf2) : bf1(bf1), bf2(bf2) { if (bf1) bf1on = true; else bf1on = false; if (bf2) bf2on = true; else bf2on = false; } bool bf1on; bool bf2on; }; // ---------------------------------------------------------------------------- // logstream class // Wrapper for a standard wostream with access to modified buffer // ---------------------------------------------------------------------------- class logstream : public wostream { private: // private member declarations logstream(); public: // public member declarations DblBuf *buf; explicit logstream(wstreambuf *StrBuf, bool isStd = false) : wostream(StrBuf, isStd), buf((DblBuf*)StrBuf) {} }; // ---------------------------------------------------------------------------- // Logging mode Class // ---------------------------------------------------------------------------- enum LogModes{LogToFile=1, LogToScreen, LogToBoth}; class LogMode { private: // private member declarations LogMode(); short mode; public: // public member declarations LogMode(short mode1) : mode(mode1) {} logstream& operator()(logstream &stream1) { switch(mode) { case LogToFile: stream1.buf->bf1on = true; stream1.buf->bf2on = false; break; case LogToScreen: stream1.buf->bf1on = false; stream1.buf->bf2on = true; break; case LogToBoth: stream1.buf->bf1on = true; stream1.buf->bf2on = true; } return stream1; } }; logstream& operator<<(logstream &out, LogMode mode) { return mode(out); } wostream& TimeStamp1(wostream &out1) { time_t time1; struct tm timeinfo; wchar_t timestr[512]; // Get current time and convert it to a string time(&time1); localtime_s (&timeinfo, &time1); wcsftime(timestr, 512,L"[%Y-%b-%d %H:%M:%S %p] ",&timeinfo); return out1 << timestr; } // ---------------------------------------------------------------------------- // MyLog class // Logs events to both file and screen // ---------------------------------------------------------------------------- class MyLog { private: // private member declarations MyLog(); auto_ptr<DblBuf> buf; string mErrorMsg1; string mErrorMsg2; string mErrorMsg3; string mErrorMsg4; public: // public member declarations explicit MyLog(string FileName1, wostream *ScrLog1, locale utf8locale1); ~MyLog(); void NewEvent(wstring str1, bool TimeStamp = true); string FileName; wostream *ScrLog; wofstream File; auto_ptr<logstream> Log; locale utf8locale; }; // ---------------------------------------------------------------------------- // MyLog constructor // ---------------------------------------------------------------------------- MyLog::MyLog(string FileName1, wostream *ScrLog1, locale utf8locale1) : // ctors mErrorMsg1("Failed to open file for application logging!

• BizTalk Business Rules Engine - Repeating Elements Question

  - by Andrew Cripps

  Hello I'm trying to create what I think should be a relatively simple business rule to operate over repeating elements in an XML schema. Consider the following XML snippet (this is simplified with namespaces removed, for readability): <Root> <AllAccounts> <Account id="1" currentPayment="10.00" arrearsAmount="25.00"> <AllCustomers> <Customer id="20" primary="true" canSelfServe="false" /> <Customer id="21" primary="false" canSelfServe="false" /> </AllCustomers> </Account> <Account id="2" currentPayment="10.00" arrearsAmount="15.00"> <AllCustomers> <Customer id="30" primary="true" canSelfServe="false" /> <Customer id="31" primary="false" canSelfServe="false" /> </AllCustomers> </AllAccounts> </Root> What I want to do is to have two rules: Set /Root/AllAccounts/Account[x]/AllCustomers/Customer[primary='true']/canSelfServe = true IF arrearsAmount < currentPayment Set /Root/AllAccounts/Account[x]/AllCustoemrs/Customer[primary='true']/canSelfServer = false IF arrearsAmount = currentPayment Where [x] is 0...number of /Root/AllAccounts/Account records present in the XML. I've tried two simple rules for this, and each rule seems to fire x * x times, where x is the number of Account records in the XML. I only want each rule to fire once for each Account record. Any help greatly appreciated! Thanks Andrew

• Trouble running setup package after Publishing in Visual Studio 2008

• Why is Available Physical Memory (dwAvailPhys) > Available Virtual Memory (dwAvailVirtual) in call G

  - by Andrew

  I am playing with an MSDN sample to do memory stress testing (see: http://msdn.microsoft.com/en-us/magazine/cc163613.aspx) and an extension of that tool that specifically eats physical memory (see http://www.donationcoder.com/Forums/bb/index.php?topic=14895.0;prev_next=next). I am obviously confused though on the differences between Virtual and Physical Memory. I thought each process has 2 GB of virtual memory (although I also read 1.5 GB because of "overhead". My understanding was that some/all/none of this virtual memory could be physical memory, and the amount of physical memory used by a process could change over time (memory could be swapped out to disc, etc.)I further thought that, in general, when you allocate memory, the operating system could use physical memory or virtual memory. From this, I conclude that dwAvailVirtual should always be equal to or greater than dwAvailPhys in the call GlobalMemoryStatus. However, I often (always?) see the opposite. What am I missing. I apologize in advance if my question is not well formed. I'm still trying to get my head around the whole memory management system in Windows. Tutorials/Explanations/Book recs are most welcome!

• Bare-metal virtualisation for the desktop

  - by Andrew Taylor

  Hi, Does anyone have any knowledge about bare-metal virtualisation products? I'm interested in building a new desktop machine for home, I've been looking at the Intel Quad Core processors and I'd like to put 8GB of RAM in there, but, it got me thinking about making the most out of the available resources. I thought if I could get a good 64bit machine, put some bare-metal virtualisation on, then have a primary system, I'd also be able to bring up some extra virtualised systems as and when I needed. I know most of the bare metal systems are designed for the server market, but, is there anything out there that works well for a desktop. What are the caveats? I presume I won't be able to make the most out of any video cards I could buy, what about just getting a decent screen resolution, will this be a problem? I run a single 24" screen. What about DVD/CD writing, is this possible? I'd like to re-rip my CD collection, I was hoping the quad 64Bit goodness would help me out with the encoding. I currently use a Mac and couldn't go back to windows so that leaves Linux, I was thinking a primary OS of ubuntu. Does this make a difference? Thanks Andrew

• Need Advice on designing ATL inproc Server (dll) that serves as both a soure and a sink of events.

  - by Andrew

  Hi, I need to design an ATL inproc server that besides exposing methods and properties, also can fire events (source) and serve as a sink for a third party COM control that fires events. I would assume that this is a fairly common requirement. I can also foresee several "gotchas" that I would like to read up on before commencing the design. My questions/concerns are: Can someone point me to an example? Which threading model to use? Should I have a seperate COM object for the sink? Should I, and how do I, protect certain memory. For example, my server will receive data from the third party control. It will save this, and in some cases, fire an event to interested clients. The interested clients will request the data through a standard method or property. I did try to research this myself. I can find many examples of COM servers that are soures, and some that are sinks, but never both. The only post I did find was this: http://www.generation-nt.com/us/atl-control-an-event-source-sink-help-9098542.html Which strongly advocates putting the sink on a seperate COM object. Any leads, tutorials or ideas would be much appreciated. Thanks, Andrew

  I'm writing some JDBC code which calls a Oracle 11g PL/SQL procdedure which has a Custom Object return type. Whenever I try an register my return types, I get either ORA-03115 or PLS-00306 as an error when the statement is executed depending on the type I set. An example is below: PLSQL Code: Procedure GetDataSummary (p_my_key IN KEYS.MY_KEY%TYPE, p_recordset OUT data_summary_tab, p_status OUT VARCHAR2); Java Code: String query = "beginmanageroleviewdata.getdatasummary(?, ?, ?); end;"); CallableStatement stmt = conn.prepareCall(query); stmt.setInt(1, 83); stmt.registerOutParameter(2, OracleTypes.CURSOR); // Causes error: PLS-00306 stmt.registerOutParameter(3, OracleTypes.VARCHAR); stmt.execute(stmt); // Error mentioned above thrown here. Can anyone provide me with an example showing how I can do this? I guess it's possible. However I can't see a rowset OracleType. CURSOR, REF, DATALINK, and more fail. Apologies if this is a dumb question. I'm not a PL/SQL expert and may have used the wrong terminology in some areas of my question. (If so, please edit me). Thanks in advance. Regs, Andrew

• What's the fastest way to bulk insert a lot of data in SQL Server (C# client)

  - by Andrew

  I am hitting some performance bottlenecks with my C# client inserting bulk data into a SQL Server 2005 database and I'm looking for ways in which to speed up the process. I am already using the SqlClient.SqlBulkCopy (which is based on TDS) to speed up the data transfer across the wire which helped a lot, but I'm still looking for more. I have a simple table that looks like this: CREATE TABLE [BulkData]( [ContainerId] [int] NOT NULL, [BinId] [smallint] NOT NULL, [Sequence] [smallint] NOT NULL, [ItemId] [int] NOT NULL, [Left] [smallint] NOT NULL, [Top] [smallint] NOT NULL, [Right] [smallint] NOT NULL, [Bottom] [smallint] NOT NULL, CONSTRAINT [PKBulkData] PRIMARY KEY CLUSTERED ( [ContainerIdId] ASC, [BinId] ASC, [Sequence] ASC )) I'm inserting data in chunks that average about 300 rows where ContainerId and BinId are constant in each chunk and the Sequence value is 0-n and the values are pre-sorted based on the primary key. The %Disk time performance counter spends a lot of time at 100% so it is clear that disk IO is the main issue but the speeds I'm getting are several orders of magnitude below a raw file copy. Does it help any if I: Drop the Primary key while I am doing the inserting and recreate it later Do inserts into a temporary table with the same schema and periodically transfer them into the main table to keep the size of the table where insertions are happening small Anything else? -- Based on the responses I have gotten, let me clarify a little bit: Portman: I'm using a clustered index because when the data is all imported I will need to access data sequentially in that order. I don't particularly need the index to be there while importing the data. Is there any advantage to having a nonclustered PK index while doing the inserts as opposed to dropping the constraint entirely for import? Chopeen: The data is being generated remotely on many other machines (my SQL server can only handle about 10 currently, but I would love to be able to add more). It's not practical to run the entire process on the local machine because it would then have to process 50 times as much input data to generate the output. Jason: I am not doing any concurrent queries against the table during the import process, I will try dropping the primary key and see if that helps. ~ Andrew
