• Connect to SQL Server Compact Edition in SSIS

  - by user218795

  Till now I've been exporting data INTO the SQL Server CE database, but now in SSIS I'm attempting to source data that was inserted in a previous step of the import. The SSIS fails during validation with the following error Error: Microsoft.SqlServer.Dts.Runtime.DtsCouldNotCreateManagedConnectionException: Could not create a managed connection manager. I am attempting to use the ADO NET Source that connects to the Data Source using the Microsoft.SqlServerCe.Client.3.5 provider (i.e. ADO.NET connection manager). I CAN preview the data in the ADO.NET Source editor, but the package validation fails due to the above error.

• Sublime Text LaTeXTools console autohide

  - by DCh

  The build script in the LaTeXTools plugin for Sublime Text editor pops up the console, where the result of the compilation is written. I would like the console to auto-hide once the compilation is finished and there are no errors (and to stay open otherwise). I knew how to achieve this with Sublime Text 2. (I think I inserted two lines sublime.active_window().run_command("show_panel", {"panel": "console", "toggle": True})) somewhere in the build script.) How to achieve this behavior with Sublime Text 3? How to (properly) achieve this behavior with Sublime Text 2?

• Using RVM with GVim (Cream): rvm command not found.

  - by Alan Peabody

  I am trying to move to GVim(cream) as my primary editor on Ubuntu. I am using the wonderful rails.vim, however I also am using RVM. Rvm works fine when doing things in a shell, and the ruby version I would like to use in rails.vim is the version set as default (but not the system version). When I try to run things like :Rgenerate migration migration_name I get: ... Missing Rails 2.3.8 gem. ... If I try: :!rvm use default I get: /bin/bash: rvm: command not found Obviously cream is not using my bash profile. What can I do to remedy this and get it working? Thanks.

• Resize transparent images using C#

  - by MartinHN

  Does anyone have the secret formula to resizing transparent images (mainly GIFs) without ANY quality loss - what so ever? I've tried a bunch of stuff, the closest I get is not good enough. Take a look at my main image: http://www.thewallcompany.dk/test/main.gif And then the scaled image: http://www.thewallcompany.dk/test/ScaledImage.gif //Internal resize for indexed colored images void IndexedRezise(int xSize, int ySize) { BitmapData sourceData; BitmapData targetData; AdjustSizes(ref xSize, ref ySize); scaledBitmap = new Bitmap(xSize, ySize, bitmap.PixelFormat); scaledBitmap.Palette = bitmap.Palette; sourceData = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, bitmap.PixelFormat); try { targetData = scaledBitmap.LockBits(new Rectangle(0, 0, xSize, ySize), ImageLockMode.WriteOnly, scaledBitmap.PixelFormat); try { xFactor = (Double)bitmap.Width / (Double)scaledBitmap.Width; yFactor = (Double)bitmap.Height / (Double)scaledBitmap.Height; sourceStride = sourceData.Stride; sourceScan0 = sourceData.Scan0; int targetStride = targetData.Stride; System.IntPtr targetScan0 = targetData.Scan0; unsafe { byte* p = (byte*)(void*)targetScan0; int nOffset = targetStride - scaledBitmap.Width; int nWidth = scaledBitmap.Width; for (int y = 0; y < scaledBitmap.Height; ++y) { for (int x = 0; x < nWidth; ++x) { p[0] = GetSourceByteAt(x, y); ++p; } p += nOffset; } } } finally { scaledBitmap.UnlockBits(targetData); } } finally { bitmap.UnlockBits(sourceData); } } I'm using the above code, to do the indexed resizing. Does anyone have improvement ideas?

• Multiple comosite applications on same WSDL endpoint with OPEN-ESB

  - by Simon Thompson

  Just learning how Open-ESB (GlassFishESB) works and evaluating it for a project. One point I do not understand is that if I have a Composite application bound to an incoming web service (hosted on the glassfish server) can I get muple composite applications to consume this message ? If so is it done by A) simply deploying the multiple composite applications each referencing the save URL and same WSDL B) include each JBI module in the CASA editor and deploy a single composite application with all parts included (will this reduce scaling?) C) create a new composite application which has a BPEL process to send the in message to new endpoints for each compisite applciation . My feeling is that option A should work?

• How to optimize this algorithm?

  - by Bakhtiyor

  I have two sets of arrays like this for example. $Arr1['uid'][]='user 1'; $Arr1['weight'][]=1; $Arr1['uid'][]='user 2'; $Arr1['weight'][]=10; $Arr1['uid'][]='user 3'; $Arr1['weight'][]=5; $Arr2['uid'][]='user 1'; $Arr2['weight'][]=3; $Arr2['uid'][]='user 4'; $Arr2['weight'][]=20; $Arr2['uid'][]='user 5'; $Arr2['weight'][]=15; $Arr2['uid'][]='user 2'; $Arr2['weight'][]=2; The size of two arrays could be different of course. $Arr1 has coefficient of 0.7 and $Arr2 has coefficient of 0.3. I need to calculate following formula $result=$Arr1['weight'][$index]*$Arr1Coeff+$Arr2['weight'][$index]*$Arr2Coeff; where $Arr1['uid']=$Arr2['uid']. So when $Arr1['uid'] doesn't exists in $Arr2 then we need to omit $Arr2 and vice versa. And, here is an algorithm I am using now. foreach($Arr1['uid'] as $index=>$arr1_uid){ $pos=array_search($arr1_uid, $Arr2['uid']); if ($pos===false){ $result=$Arr1['weight'][$index]*$Arr1Coeff; echo "<br>$arr1_uid has not found and RES=".$result; }else{ $result=$Arr1['weight'][$index]*$Arr1Coeff+$Arr2['weight'][$pos]*$Arr2Coeff; echo "<br>$arr1_uid has found on $pos and RES=".$result; } } foreach($Arr2['uid'] as $index=>$arr2_uid){ if (!in_array($arr2_uid, $Arr1['uid'])){ $result=$Arr2['weight'][$index]*$Arr2Coeff; echo "<br>$arr2_uid has not found and RES=".$result; }else{ echo "<br>$arr2_uid has found somewhere"; } } The question is how can I optimize this algorithm? Can you offer other better solution for this problem? Thank you.

• PHP5 what's wrong with my syntax?

  - by myxospsm

  Hey, I've never developed before and I'm a bit puzzled, what is wrong with my syntax here? private static $instance; //holder of Mongo_Wrapper public $connected = true; private $mongo = null; // The mongo connection affiliation private $database = null; // The database we are working on with this function: public function mongo_connect($db_name) { if (! self::connected) { $this->mongo = new Mongo; //TODO: error handle this whole sharade: throw new Kohana_Database_Exception('Cant connect', NULL, 503); $this->connected = true; } $this->database = $this->mongo->$db_name; //set the database we are working on return $connected; } I'm sorry, wmd-editor is giving me hell posting the code. Thank you!

• CoffeeScript on Windows?

  - by Nick Perkins

  How can I try CoffeeScript on Windows? The installation instructions are only for *nix: http://jashkenas.github.com/coffee-script/#installation EDIT: I don't think I need node.js -- I am just writing javascript for web pages, (using some jQuery, etc)...So all I really want is simple way to write CoffeeScript and "compile" it down to JavaScript. Isn't there a Ruby program that would do it? Or even better, a windows exe? (i dont use ASP.NET either...i use Python/Django) FINAL EDIT: Thanks for the help -- In the end I installed VirtualBox and created a virtual Linux machine which I now use to program coffeescript with node.js. (It was surprisingly easy to start using VirtualBox -- easier than doing the Cygwin thing). I run jEdit (for which you can get a CoffeeScript syntax highlighter) and I put the corresponding js file side-by-side with the coffeescript file. When I compile the coffeescript to js, the editor automatically re-loads the new javascript, which allows me to check that it has compiled the way I expect (which is a good thing while learning the coffeescript syntax).

• VI/VIM file handling

  - by Abhimanyu

  Nowa days I'm working with the Vi editor with the positive approach that you can do most things using it - unlike other editors. I came across one problem: Let's assume I have open a folder with vi <folder name> so it opens the folder in Vi and lists the files in that folder. I select a file and read the content, then I want to go back to the previous view which has filenames listed so it is easy to choose another file. But don't know how to achieve this. I'm hoping some method should be there to achieve this.

• Update table.column with another table.column with common joined column

  - by Matt

  Hit a speed bump, trying to update some column values in my table from another table. This is what is supposed to happen when everything works Correct all the city, state entries in tblWADonations by creating an update statement that moves the zip city from the joined city/state zip field to the tblWADonations city state TBL NAME | COLUMN NAMES tblZipcodes with zip,city,State tblWADonations with zip,oldcity,oldstate This is what I have so far: UPDATE tblWADonations SET oldCity = tblZipCodes.city, oldState = tblZipCodes.state FROM tblWADonations INNER JOIN tblZipCodes ON tblWADonations.zip = tblZipCodes.zip Where oldCity <> tblZipcodes.city; There seems to be easy ways to do this online but I am overlooking something. Tried this by hand and in editor this is what it kicks back. Msg 8152, Level 16, State 2, Line 1 String or binary data would be truncated. The statement has been terminated. Please include a sql statement or where I need to make the edit so I can mark this post as a reference in my favorites. Thanks!

• Client side html markdown conversion

  - by DNN

  Hello, I've been trying to create a client side editor which allows the end user to create content in html or markdown. The user has two tabs for switching between the two. I managed to find some javascript that converts markdown to html, so if a user has been writing markdown and switches to the html tab, the html equivilant is shown. I haven't been able to find a javascript that converts html to markdown, only a python script. The python script is obviously server side. The tabs are just hyperlinks with script in there. Is there any way I can convert the markdown html when the user clicks the tab? The system has been created in python/django for reference Thanks

• Preserving text formatting for dynamic website

  - by Mohit

  Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit

• Visual Studio Performance when editing XAML/Silverlight files

  - by driAn

  When I work on Silverlight projects within Visual Studio 2008, I regularly notice that the XAML editor hangs for up to 10 seconds. This because Visual Studio consumes 100% CPU during that timeframe. Any ideas how I could fix that? I assume this is some kind of background compiling for itellisense or something similiar. It happens during editing, multiple times an hour, without me doing any special actions. System: Server 2008 Std Visual Studio 2008 SP1 latest updates... I wonder if anyone else experienced this issue. Any help would be appreciated.

• Using Kate with Simple Build Tool (SBT)

  - by Stefan

  Hello I am working with the Kate editor based on the lack of other good tools for Scala development, I am also using IntelliJ however it still has some bugs, and are slow enough to make me impatient. I have just startet using both Kate and SBT, and in that regard I have a little challenge I hope there is an answer for out there on "The Internet". I am using the standard "Build plugin" in Kate and has changed the commands from make to sbt. This works fine, and I am also getting a error report when the sbt fails during compile time. However I really wish to know if it is possible to integrate the compile errors into Kate such that it would be shown under "Errors and Warnings" instead of just in the output tab, where I have to do a manual search for the compile errors. Im guessing that it has something to do with the format of the output, if that is the case maybe it is "just" a smaller adjustment I need to make to the parsing language.

• CKEditor adds unwanted newline to '<p>'

  - by dove

  If I load up a set of paragraphs then the editor replaces my <p> with <p>&#x9; It means <p>paragraph 1</p> <p>paragraph 2</p> <p>paragraph 3</p> ends up like <p> paragraph 1</p> <p> paragraph 2</p> <p> paragraph 3</p> Has anyone come across this and know how to fix? It seems to be an issue but no response on their forum My humble guess from looking at their source is that this was introduced to remove a different bug. I've looked at the obvious configuration settings and the like.

• Required Working Precision for the BBP Algorithm?

  - by brainfsck

  Hello, I'm looking to compute the nth digit of Pi in a low-memory environment. As I don't have decimals available to me, this integer-only BBP algorithm in Python has been a great starting point. I only need to calculate one digit of Pi at a time. How can I determine the lowest I can set D, the "number of digits of working precision"? D=4 gives me many correct digits, but a few digits will be off by one. For example, computing digit 393 with precision of 4 gives me 0xafda, from which I extract the digit 0xa. However, the correct digit is 0xb. No matter how high I set D, it seems that testing a sufficient number of digits finds an one where the formula returns an incorrect value. I've tried upping the precision when the digit is "close" to another, e.g. 0x3fff or 0x1000, but cannot find any good definition of "close"; for instance, calculating at digit 9798 gives me 0xcde6 , which is not very close to 0xd000, but the correct digit is 0xd. Can anyone help me figure out how much working precision is needed to calculate a given digit using this algorithm? Thank you,

  Hi, I have a strange problem, Firefox doesn't show the CSS of the page I'm doing, but Internet Explorer does. I have tried at home and at one of my friend's home, and it happens in both. But, if I go to the Firefox Web Developer toolbar (i have it installed) and select CSS=Edit CSS, then the styles appears appears in the page and in the editor! As soon I close it, they disappears again. I have no idea what the problem is :( Do you have any idea about what could be the problem? thanks in advance.

• Separating Strings from a CSV File in SSIS 2008

  - by David Stein

  I have data which resembles the following: "D.STEIN","DS","01","ALTRES","TTTTTTFFTT" "D.STEIN","DS","01","APCASH","TTTTTTFFTT" "D.STEIN","DS","01","APINH","TTTTTTFFTT" "D.STEIN","DS","01","APINV","TTTTTTFFTT" "D.STEIN","DS","01","APMISC","TTTTTTFFTT" "D.STEIN","DS","01","APPCHK","TTTTTTFFTT" "D.STEIN","DS","01","APWLNK","TTTTTTFFTT" "D.STEIN","DS","01","ARCOM","TTTTTTFFTT" "D.STEIN","DS","01","ARINV","TTTTTTFFTT" I need to break out the final string into separate columns for import into a SQL Table, one letter into each field. Therefore, "TTTTTTFFTT" will be broken out into 10 separate fields each with a single bit value. I've used a Flat File Source Editor to load the data. How do I accomplish the split?

• reference suggestion in latex windows (multi-file structure)

  - by voodoomsr

  There is some editor of latex that managed the labels for a multifile document?. I tried with TexMaker and LED, and they offers me suggestions about the labels present in the actual document and in the "Master" document but not the labels present in other files of the structure. I made a script to find those other labels but it will be real good that the suggestions covers all the file structure automatically. Finally i tried with Vim and Latex-Suite, this extension has that posibility but i have problem configuring the grep program despite having followed all the instructions found in their website and in the help files, :(. the structure is like this: document.tex mystyle.sty mybibliography.bib tex/file1.tex tex/file2.tex tex/... img/img1.png img/img2.png . . .

• Haskell Console IO in notepad++

  - by IVlad

  I've recently started to learn Haskell. I have this code module Main where import IO main = do hSetBuffering stdin LineBuffering putStrLn "Please enter your name: " name <- getLine putStrLn ("Hello, " ++ name ++ ", how are you?") I'm using the GHC compiler together with the notepad++ editor. The problem is the interaction goes like this: Process started Vlad Please enter your name: Hello, Vlad, how are you? <<< Process finished. As you can see, output is only written after I input something. This was a bit unexpected, as I was sure the program would first ask for my name, then I'd get to enter it and then it would say hello. Well, that's exactly what happens if I run the exe manually, yet not if I run it with notepad++ and use its console wrapper... How can I make notepad++ display the output when it should, and not all of it just before the program terminates? Is this even possible?

• Quadratic Bezier Curve: Calculate Tangent

  - by stefan.at.wpf

  I have a quadratic bezier curve and I want to calculate the slope of the tangent in a given point. For example, let it be the middlepoint of the quadratic bezier curve, therefore t=0.5 (please see the link below for a picture of this). I've calculated the first derivative of the formula for the quadratic bezier curve; however I get 400 as value for the slope, though it should be 0. Maybe I'm using the first derivative in a wrong way? I know I could also calculate the tangents using trigonometric functions; however I'd like to do it using the first derivative, shouldn't this be possible? Thanks for any hint! For clarification / please note: I'm interested in a general way to get the slope in a arbitrary given point on a quadratic bezier curve, not only to get the tangent in the start- and end point. A picture of my problem including the text above: http://cid-0432ee4cfe9c26a0.skydrive.live.com/self.aspx/%c3%96ffentlich/Quadratic%20Bezier%20Curve.pdf Thank you very much for any hint!
