• database vs flat file, which is a faster structure for "regex" matching with many simultaneous reque

  - by Jamex

  Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? Addition info: If I want to find all the cities have the pattern "cis" in their names. Which is better/faster, using regex or string functions? Please recommend a strategy TIA

• Is it possible to get last modified date from an assets file?

  - by Nathan Fig

  Hi, all Bizarre question: is it possible to get the last modified date of a file in the assets folder, or would that be pointless and impossible? I ask because I'm copying a read-only database out of there into the data folder on application start up, but would rather only perform the copy if the existing file is older than the one stored in the assets folder (or if the file doesn't exist). If that's not possible, anyone know of a better convention? I can post that in a separate question if needed. TIA!

• How to send reminder notifications to subscribers for renewal from SQL Server 2005?

  - by codemonkie

  I have a table in SQL DB, namely dbo.subscribers, it contains following columns: -SubscriberID -JoinDateTime The business logic says a subscription last for 2 weeks and a reminder should be sent after 7 days from the JoinDateTime. The way that the system was designed to send reminders are via a URL call, e.g. http://xxx.xxx.xxx.xxx/renew_userid=SubscriberID/ and that can only be called from our webserver which is the only whitelisted IP machines given. Currently there is a windows service written to query the DB once a day at midnight to grab all expiring subscribers and send them reminders, however this batch approach only sends reminders to the nearest date, well, I could have set the interval down from 1 day to 1 hour such that the service can send notifications out closer to the exact JoinDateTime + 7 days requirements. I have heard a stored procedure can be written and perform task like this to a nearly real-time manner, if yes, please give me some hints on how to do it. Another question is - is SSRS bit of an overkill to perform things like this? Please advice. TIA

• Detach many subdirectories into a new, separate Git repository

  - by prisonerjohn

  This question is based on http://stackoverflow.com/questions/359424/detach-subdirectory-into-separate-git-repository Instead of detaching a single subdirectory, I want to detach a couple. For example, my current directory tree looks like this: /apps /AAA /BBB /CCC /libs /XXX /YYY /ZZZ And I would like this instead: /apps /AAA /libs /XXX The --subdirectory-filter argument to git filter-branch won't work because it gets rid of everything except for the given directory the first time it's run. I thought using the --index-filter argument for all unwanted files would work (albeit tedious), but if I try running it more than once, I get the following message: Cannot create a new backup. A previous backup already exists in refs/original/ Force overwriting the backup with -f Any ideas? TIA

• Question regarding CGRectIntersectsRect and rotated rectangular image

  - by user309030

  Hi guys, I've got a long rectangular image which is rotated at different kind of angles. However the frame of the rectangular image does not rotate along with the image and instead, the rotation causes the frame to to become larger to fit the rotated image. So when I used CGRectIntersectsRect, the collision detection is totally off because the other image colliding with the rectangular image will collide before it even reaches the visible area of the rect image. In case you don't really know what I'm talking about, have a look at the ascii drawing: normal rectangular image frame, O - pixels, |, – - frame |----------| |OOOOOOOOOO| |----------| after rotation |----------| |O | | O | | O | | O | | O | | O | | O | | O | | O | |----------| I've read through some of the collision articles but all of them are talking about collision with a normal straight rectangle and what I really want is collision with a slanted image, preferably pixel collision detection. TIA for any suggestions made.

• Parsing an Open XML doc via styled blocks

  - by Chris B. Behrens

  I'm working with docx docs, and I need to parse a document into sections on the basis of headings styled with the "heading 1" style. So if I had a doc like this (markup is pseudocode): <doc> <title style>Doc Title</title style> <heading1>First Section</heading1> ... <heading2>Second Section</heading2> ... <heading3>Third Section</heading3> ... </doc> I'd want to break this into a doc with four sections, the first being the content that precedes the first section. I figure that this is probably pretty simple once you're familiar with Open XML, but I am not. TIA.

• regex pattern to match only strings that don't contain spaces PHP

  - by Jamex

  Hi, I want to match the word/pattern that is contained in the variable, but only match against the words that don't have white spaces. Please give suggestions. $var = 'look'; $array = ('look', 'greatlook', 'lookgreat', 'look great', 'badlook', 'look bad', 'look ', ' look'); matches words: look, greatlook, lookgreat, badlook non matches: look great, bad look, look (trailing space(s)), (space(s)) look. The syntax of the below functions are OK, but it matches everything $match = preg_grep ("/$var/", $array); $match = preg_grep ("/^$var/", $array); (match words with 'look' at the start) but when I include the [^\s], it gives an error $match = preg_grep ("/$var[^\s]/", $array); Parse error: syntax error, unexpected '^', expecting T_STRING or T_VARIABLE TIA

• Reporting Services Textbox Format Question

  - by coson

  Good Day, I am creating a report with Reporting Services and am using several text boxes horizontally aligned next to each other. I would like to put periods so that report looks like: 1234 Robert Jones................... (234) 921-4922 1235 Jennifer Wilson................ (919) 582-2914 Is this possible to right-pad the text box with periods, or would I need to roll out some code to accomplish the above effect. I tried doing this and the results looked like: 1234 Robert Jones............... (234) 921-4922 1235 Jennifer Wilson.......... (919) 582-2914 Is something like this even possible? TIA, coson

• SharePoint WSS 3.0 - Fastest approach to build data-bound forms?

  - by Rusty Scupper

  Pardon the vague question, but I've just inherited a project to build a couple dozen forms pulling data from a SQL 2005 database. The forms are mostly standard database lookups with just a couple updates so the data layer is very simple -- I'm the DBA -- but we just recently started using SharePoint WSS 3.0 for a departmental web site and I would prefer to integrate these forms into WSS rather than build a separate standalone ASP.NET app. I'm hoping there is some RAD framework out there that integrates with WSS for data bound forms. I've been searching online, but haven't found anything very promising and the data viewer web part in SharePoint Designer looks complicated to integrate with an external SQL database. TIA, Rusty

• "SQL Server does not exist or access denied." upon VB.Net Deployment

  - by JasonMHirst

  Have built a small VB.Net app in VS2010. The connection string to the SQL Server is as follows: <connectionStrings> <add name="IWSR_DataDownloadWizard.My.MySettings.sqlConnection" connectionString="Provider=SQLOLEDB.1;Data Source=SQLServer;Integrated Security=SSPI;Initial Catalog=IWSROL" providerName="System.Data.OleDb" /> </connectionStrings> Within the VS2010 environment AND on my machine, the connection works perfectly, however when I deploy to clients I get an error message of: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. I've tried to search the net for solutions, have seen a few instances of people saying to NOT use the Server Name but the IP Address instead (this doesn't work) and some saying to remove the "Provider=SQLOLEDB.1", again this doesn't work. Can anyone suggest a solution please? Further information: Development System is Windows7 using VS2010 Deployment systems are a combination of Windows XP, Windows 2000 and Windows 7 SQL Server is SQL2000 (soon to be SQL2005). TIA

• Resource interpreted as other but transferred with MIME type text/html.

  - by Zhami

  I'm transferring fragments of HTML via Ajax. Safari (4.0.5) reports: "Resource interpreted as other but transferred with MIME type text/html." The file name of the file I get has a .html extension. The server does set the header for this: Content-Type:text/html As I said, the content is a fragment of HTML, which is injected into the page (with jQuery). The contents of the file look like: <html> ... some valid html ... </html> What else might Safari need to see to make it interpret the received content as HTML? TIA.

• Wrong SQLServer syntax: need help!

  - by user512602

  Hi, this is what I want to achieve: 4 tables are involved: Players with PlayerID as PK, Competitions with CompetID as PK Results with ResultID as PK and CompetID as FK And the 4th table: PlayerResultts with ResultID + PlayerID as PK and CompetID as new column I created. Competitions, results and PlayerResults are already populated and quite large (300000 PlayerResults so far). In order to populate the PlayerResults.CompetID column, I try a Update ... (Select....) request but I'm not aware of the right syntax and it fails. Here is my feeble attempt: update PlayerResults set competid = (select distinct(r.competid) from results r, playerresults p where r.resultID = p.resultid) Error is (of course): "Msg 512, Level 16, State 1, Line 1 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , , = or when the subquery is used as an expression." Can someone put me in the right direction? TIA

• Silverlight 4 application on localhost runs extremely slow

  - by rams

  Silverlight 4 app running in IE8 and hosted on VS2010 internal webserver. The website takes atleast a minute to download the xap and code runs slow on client (IE8). I am running the app in debug mode and have turned intellitrace off. Symbol loading is also turned off. However if I kill the VS webserver, clean the solution, the app runs fast. 3 debugging sessions later, the app slows to a crawl. Have also tried turning off McAfee live scanning but no use. Looked in event log for any clue but found none. What could be the cause of the slowness? TIA rams

• Can I safely move my project to .NET 4.0?

  - by Decker

  I've migrated my project to VS2010 but have not yet targeted .NET 4.0. It's currently targeting 3.5 SP1 (and CLR 2). The project relies on several third party components -- mostly open source -- that were presumably built against the 2.0 CLR. Can I simply retarget my project to the 4.0 runtime? Or do I have to get new versions of all the referenced assemblies on which it depends? I've read a little about the new in-process side-by-side feature of .NET 4.0, but I don't think it applies here (the example I read was about two different .NET plug ins to an office application). My situation is different. My solution directly references assemblies and I wouldn't think side-by-side applies -- unless I don't understand its purpose. TIA

• Include a unique URL in EXE

  - by John Grey

  Hi :) I want to give users of my site the ability to upload their software/hardware configuration automatically on Windows. So I'm thinking of having an EXE file download, and somehow put in that EXE a unique URL for each user. When the data is collected, the program would just posts some JSON to that URL. How can I do it? I'm most familiar with .NET platform. Tools like this do exist, for example Blizzard uses this approach for their beta test enroll. Each user downloads a slightly different EXE. TIA

• Date range/query problem..

  - by Simon

  Am hoping someone can help me out a bit with date ranges... I have a table with 3 fields id, datestart, dateend I need to query this to find out if a pair of dates from a form are conflicting i.e table entry 1, 2010-12-01, 2010-12-09 from the form 2010-12-08, 20-12-15 select id from date_table where '2010-12-02' between datestart and dateend; That returns me the id that I want, but what I would like to do is to take the date range from the form and do a query similar to what I have got that will take both form dates 2010-12-08, 20-12-15 and query the db to ensure that there is no conflicting date ranges in the table. Am sat scratching my head with the problem... TIA

• Truncate text if it atempts to run into three lines

  - by Jigs

  I have a small about 140px wide aligned next to a picture. In total there is space for four lines of text. The first two lines are reserved for the title and there are two lines of other info. I want the title to be cut if it spans more than two lines else it will push the other info out of line with the bottom of the image. The only solution I could think of was to create a div the height of two lines with an overflow to hidden. However, if the title is only one line it leaves a big gap. The solution can be Jquery, plain javascript, CSS or even PHP (if its possible). TIA

• Adding and altering multiple text items to a Canvas -- what approach?

  - by philologon

  I am attempting to use a Canvas to create a simple Cad application. I have been able to get lines to draw as I want. For now the only other thing I need is text. The user should be able to edit the text in place. ?Is one of these better to use for this over the others? Rich Text TextBlock TextBox Label A more important question, though, is once I have chosen which class to use for implementation, how do I set and get the text value in code? Since the app is in essence a cad application, text will be added, deleted, and altered often, so I am not attempting to put these in XAML, but code-behind. That is why I am asking about how to do this in code. If the answer is "use X.SetValue()" (or that family of methods), then please tell me what I am supposed to do with the required DependencyProperty reference? TIA. Paul

• Finding Line Beginning using Regular expression in Notepad++

  - by Michel Merlin

  Finding Line Beginning using Regular expression in Notepad++ (Sorry for this newbie question) I want to strip a 4000-line HTML file from all the jQuery "done" stuff, e.g.: <DIV class=menu done27="1" done26="0" done9="1" done8="0" done7="1" done6="0" done4="20"> should be replaced with: <DIV class=menu> In http://www.zytrax.com/tech/web/regex.htm#experiment I can do it with RE: [ ^]done[0-9]+="[0-9]+" but in Notepad++ 5.6.8 UNICODE Search Find, Search mode = Regular expression, putting this RE in the "Find what" field won't work (it will only find the 5 occurrences starting with a space, it will miss the 2 occurrences starting at the beginning of a line; IOW, the caret for line beginning, or the alternating it with a space, fails). How do I? TIA, Versailles, Wed 21 Apr 2010 10:18:20 +0200

• vb.net add text to form without interaction

  - by user228058

  I have a winform project which lists all the files in a specified folder. It allows the user to select a new destination for each file, and when the user has chosen the destinations for all files that he would like to be moved, it moves the files, one by one. My next step is, I need to display a confirm form when the files are being moved, and add each file's name and destination to the confirm form as it is being moved. My question is: How can I add more text to the confirm form's controls after I already loaded it (using confirm.showdialog() from my other form, without any user interaction? I imagine that I need to do it from the original form, because it needs to display each one when it starts to move that file, but I'm open to any suggestions:) TIA

• Multiple Table Joins to Improve Performance?

  - by EdenMachine

  If I have a table structure like this: Transaction [TransID, ...] Document [DocID, TransID, ...] Signer [SignerID, ...] Signature [SigID, DocID, SignerID, ...] And the business logic is like this: Transactions can have multiple documents Documents can have multiple signatures And the same signer can have multiple signatures in multiple documents within the same transaction So, now to my actual question: If I wanted to find all the documents in a particular transaction, would it be better, performance-wise, if I also stored the TransID and the DocID in the Signer table as well so I have smaller joins. Otherwise, I'd have to join through the Signature Document Transaction Documents to get all the documents in the transaction for that signer. I think it's really messy to have that many relationships in the Signer table though and it doesn't seem "correct" to do it that way (also seems like an update nightmare) but I can see that it might be better performance for direct joins. Thoughts? TIA!
