• highlighting non-ascii text

  - by non-techie

  As a non-techie, I would really appreciate your help on this. I have some files (html) that need to be in pure ascii form to be properly processed. Since these files are produced by humans, every so often non-ascii characters sneak in. Often it is a stray " (curled variety) or something similar that is difficult to find and need to be removed. I have found text editors (eg. textmate) that can strip out all non-ascii characters, but I need to find one that can highlight where they are, rather than remove them (as I need to remove them from the source and not the html file). I hope this makes sense and appreciate any assistance you can provide. Thanks!

• Can I convert a Stream object to a FileInfo object?

  - by Michael

  For the ExcelPackage constructor you need a FileInfo object. I rather use some kind of stream object(f.i. MemoryStream), because I don't need to save the file to the server itself, but expose it as a FileStream anyway to the user. I don't want to make files which I have to delete lateron from servers which are only there for generating purposes and never used again. Apart from that, otherwise I need also the necessary rights for the application/user on the directory/file on the server. So my question is then: How can I convert a stream object to a FileInfo object.

• Application Context in Rails

  - by Sean McMains

  Rails comes with a handy session hash into which we can cram stuff to our heart's content. I would, however, like something like ASP's application context, which instead of sharing data only within a single session, will share it with all sessions in the same application. I'm writing a simple dashboard app, and would like to pull data every 5 minutes, rather than every 5 minutes for each session. I could, of course, store the cache update times in a database, but so far haven't needed to set up a database for this app, and would love to avoid that dependency if possible. So, is there any way to get (or simulate) this sort of thing? If there's no way to do it without a database, is there any kind of "fake" database engine that comes with Rails, runs in memory, but doesn't bother persisting data between restarts?

• Visual Studio - "attach to particular instance of the process" macro

  - by Steve

  I guess prety much everyone who does a lot of debugging have a handy macro in Visual Studio (with shortcut to it on a toolbar) which when called automatically attaches to a particular process (identified by name). it saves a lot of time rather than clicking "Debug" - "Attach to the process ...", but it only works if one is running a single instance of the process one wants to attach to. If theres is more than one instance of particular process in memory - the first one (with a smaller PID?) is being choose by debugger. Does anyone have a macro which shows a dialog (if more that 1 process with a specified name running) and lets developer to select to one he/she really wants to attach to. I guess the selection could be made based on a windwow caption text (which would be suffice in most of cases) and when the particular instance is selected macro passes the PID of the process to the Debugger object? If someone has that macro or knows how to write it - please share. Thanks.

• What is technically more advanced: Python or Assembler? [closed]

  - by el ka es

  I wondered which of these languages is more powerful. With powerful I don't mean the readability, assembler would be naturally the winner here, but something resulting from, for example, the following factors: Which of them is more high-level? (Both aren't really but one has to be more) Who would be the possibly fastest in compiled state? (There is no Python compiler out there as far as I know but it wouldn't be hard writing one I suppose) Which of the both has the better code length/code action ratio? What I mean is If you get to distracted by the, compared to Python, improved readability of assembler, just think of writing plain binary/machine code as what assembler assembles to. Both languages are so basic that it should be possible to answer the question(s) in a rather objective view, I hope.

• How to setup a DotNetNuke Development Environment with Source Control?

  - by Joosh21

  My team is developing a new DotNetNuke web application and would like to know what is recommended to setup a development environment with source control and automated builds? We would like to keep the DNN source code separate from our custom modules and extensions source code. The DotNetNuke Compiled Module template for Visual Studio wants us to store the source code in the DesktopModules directory of the DNN source code and output to the DNN source code bin directory. Is this the recommended structure? I would rather keep the files in different locations, but then it becomes more difficult to run and debug locally as it would require an install of the module for each change. Also, how should an automated build deploy any changes? How have others set this up? Is there a recommended best practice?

• (Oracle Performance) Will a query based on a view limit the view using the where clause?

  - by BestPractices

  In Oracle (10g), when I use a View (not Materialized View), does Oracle take into account the where clause when it executes the view? Let's say I have: MY_VIEW = SELECT * FROM PERSON P, ORDERS O WHERE P.P_ID = O.P_ID And I then execute the following: SELECT * FROM MY_VIEW WHERE MY_VIEW.P_ID = '1234' When this executes, does oracle first execute the query for the view and THEN filter it based on my where clause (where MY_VIEW.P_ID = '1234') or does it do this filtering as part of the execution of the view? If it does not do the latter, and P_ID had an index, would I also lose out on the indexing capability since Oracle would be executing my query against the view which doesn't have the index rather than the base table which has the index?

• How can I force a major upgrade to not switch to maintenance mode using the old installation package

  - by Brian

  I have an installer that I would like to use for a major upgrade. I have done the following: Increased the version number (from a.b.c to a.b.c+1) Changed the ProductCode Kept the same UpgradeCode Made the appropriate entry in the Upgrade table Changed the component ID of an existing component Changed the name of the installer package Changed the PackageCode Basically I've done everything I can think of to force MSI to treat this as a major upgrade. However, when I attempt to install this new package, the installer log says "Product registered: entering maintenance mode" and proceeds to try to find the old installer file (which fails, since the new installer is in a different folder than was used for the original installation, and wasn't even what I wanted to happen). What am I missing? Why does the installer switch to maintenance mode right away rather than perform the major upgrade? Thanks!

• view to select specific period or latest when null

  - by edosoft

  Hi I have a product table which simplifies to this: create table product(id int primary key identity, productid int, year int, quarter int, price money) and some sample data: insert into product select 11, 2010, 1, 1.11 insert into product select 11, 2010, 2, 2.11 insert into product select 11, 2010, 3, 3.11 insert into product select 12, 2010, 1, 1.12 insert into product select 12, 2010, 2, 2.12 insert into product select 13, 2010, 1, 1.13 Prices are can be changed each quarter, but not all products get a new price each quarter. Now I could duplicate the data each quarter, keeping the price the same, but I'd rather use a view. How can I create a view that can be used to return prices for (for example) quarter 2? I've written this to return the current (=latest) price: CREATE VIEW vwCurrentPrices AS SELECT * FROM ( SELECT *, ROW_NUMBER() OVER (PARTITION BY productid ORDER BY year DESC, quarter DESC) AS Ranking FROM product ) p WHERE p.Ranking = 1 I'd like to create a view so I can use queries like select * from vwProduct where quarter = 2

• PHP pecl/memcached extension slow when setting option for consistent hashing

  - by HarryF

  Using the newer PHP pecl/memcached extension. Calls to Memcached::setOption() like; $m = new Memcached(); $m->setOption(Memcached::OPT_DISTRIBUTION, Memcached::DISTRIBUTION_CONSISTENT); are costing between 150 to 500ms - just in making the call to setOption() and as we're not using persistent connections but rather doing this on every request, it hurts. Delving deeper, setting Memcached::OPT_DISTRIBUTION to Memcached::DISTRIBUTION_CONSISTENT ends up calling update_continuum() in libmemcached which appears to be fairly intensive, although we're only passing a list of 15 memcached servers in, so somewhat surprising to see it take between 150 to 500ms to rebuild the continuum data structure. Could it be setting this option is only suitable for persistent connections, where it's called only once while making the initial connection? Or is this a bug libmemcached? Using the newer pecl/memcached extension 1.0.1 with libmemcached 0.38 Thanks.

• Windows xp printer queue issues

  - by BubbaWI

  I have a C# application (.NET 3.5 SP1) that I am printing serial numbers for product for a manufacturing company. I am using Active Reports 3 (ver. 5.2.385.2) to print these labels. However, when the printer(Zebra TLP 3842) has an issue, it seems like the printer queue reprints the print job. This causes duplicate serial numbers to be printed. Does anyone know how to ensure that this will not happen. I would rather not have a serial number print than have duplicate serial numbers.

• Is there any performance difference between Debug and Release?

  - by Lazlo

  I'm using MySql Connector .NET to load an account and transfer it to the client. This operation is rather intensive, considering the child elements of the account to load. In Debug mode, it takes, at most, 1 second to load the account. The average would be 500ms. In Release mode, it takes from 1 to 4 seconds to load the account. The average would be 1500ms. Since there is no #if DEBUG directive or the like in my code, I'm wondering where the difference is coming from. Is there a project build option I could change? Or does it have to do with MySql Connector .NET that would have different behaviors depending on the build mode?

• Drop target - where do I register the COleDropTarget variable if the view class doesn't have OnCreat

  - by Harvey

  The MSDN site says: From your view class's function that handles the WM_CREATE message (typically OnCreate), call the new member variable's Register member function. Revoke will be called automatically for you when your view is destroyed. But I don't have an OnCreate function in the ChildView class. I do have OnCreate in the CMainFrame class. Can I register it there? What are the ramifications? PLEASE NOTE: I have it working for dropping files but I want to drop the text as a file, not at a cursor location like a text cut and paste, but rather I want the application to make a buffer to hold it, and I will treat it like a file. TIA, Harvey

• best way to externalize HTML in GWT apps?

  - by Limbic System

  What's the best way to externalize large quantities of HTML in a GWT app? We have a rather complicated GWT app of about 30 "pages"; each page has a sort of guide at the bottom that is several paragraphs of HTML markup. I'd like to externalize the HTML so that it can remain as "unescaped" as possible. I know and understand how to use property files in GWT; that's certainly better than embedding the content in Java classes, but still kind of ugly for HTML (you need to backslashify everything, as well as escape quotes, etc.) Normally this is the kind of thing you would put in a JSP, but I don't see any equivalent to that in GWT. I'm considering just writing a widget that will simply fetch the content from html files on the server and then add the text to an HTML widget. But it seems there ought to be a simpler way.

• How to set a control ID in ListView Template dynamically?

  - by citronas

  A have a ListView that is rendered with multiple items. Now I want to toggle some HTML attributes with JQuery. Therefore it would be best to have access to these elements via an unique ID. But trying to create a "dynamic" and therefore unique ID by <tr runat="server" ID='<%# this.GetUniqueID() %>'> </tr> results in an error that tells me that the ID needs to be simple and cannot be set by a call to a method. I know that I can dynamically create controls in the code-behind and set the ID there. But in this case, I'd rather like to let the content be rendered by the ListView itself. That brings me to the conclusion that the idea of setting a dynically ID in the Template is totally wrong. How can I achieve the desired behaviour?

• how to change strip.text labels in ggplot with facet and margin=TRUE

  - by Andreas

  I have looked here but still can't figure it out. How do I change the strip.text.x labels in a ggplot with faceting? Specifically I am using facet_grid with margins. The strip.text label for the margin is "(all)" - but since I am in a non-english speaking country I would rather write "Total" or something similar in my native tongue. opts(stip.text.x=c(levels(facetvariabel,"Total")) does not work. Any ideas? Example (not really the best dataset for this - but I guess it will work) ggplot(cars, aes(x=dist))+geom_bar()+facet_grid(.~speed, margin=T)

• Why is C# suddenly so popular?

  - by leeand00

  Why is C# suddenly so popular? There's been like a repeat explosion in the blogs lately about it; It reminds me of the earlier part of this decade when all of those frameworks for Java came out like Spring, JSF, Hibernate, Struts, Struts2, Tapestry etc... I've actually been thinking about learning C#, and it seems to contain a lot of qualities that it has gotten from Java (aside from it being completely cross-platform) But, it almost seems like a step backwards to me...its not totally multi-platform, a language that's run by a corporation rather than a community... (But, knowing this isn't the case, I've come here to find out why it isn't...) P.S. And yes, I am aware of the Mono project so that you can run it on Linux, but isn't it always behind the curve? A new version of Java would be supported on all the platforms.

• Experiences with UI Automation and WPF

  - by soren.enemaerke

  We are developing a rather large WPF based application and would like to include some automated UI testing in our test suite (which already contains a number of unit tests). The UI Automation Framework from Microsoft partly sounds like a perfect fit for programatically launching and interacting with the application in a test setup. However, I've struggled to find solid references for samples and experiences with the technology, the articles and small samples available on MSDN is not enough to convince me that it is a solid choice. So, does anybody have real world experiences using the UI Automation Framework in their test suite? What are the caveats and the gotchas? Any best practices when written tests scripts, can you "record and replay" to a scriptable format, how much should you facilitate the testing from the application, how did you incorporate it in the automatic build? Should we be looking in another direction than the UI Automation Framework? Feel free to post you experiences here or link to some good references I might have missed

• Does UIWebView support javascript-based double-click events?

  - by Eric

  As usual, I'm trying to do something the easiest way possible, in this case implement a double-tap handler on a UIWebView like so: <div id="foo" ondblclick="clickHandler(this);" ... > It works fine in Safari and Firefox, and I know the code containing clickHandler is loading on the iPhone thanks to a now-annoying alert stmt at the end of loading. If I change ondblclick to onclick it works on both the device and the simulator. From reading similar queries it would seem that I need to intercept the taps in ... and then run my JavaScript code with the stringByEvaluatingJavaScriptFromString method, but then how do I know the JS id of the target? I no like that, would rather write a pure HTML/DOM/JS solution. Or since my app is about 80% web content, should I be using phonegap instead?

• how to load an image to a grid using pygame, instead of just using a fill color?

  - by yao jiang

  I am trying to create a "map of a city" using pygame. I want to be able to put images of buildings in specific grid coords rather than just filling them in with a color. This is how I am creating this map grid: def clear(): for r in range(rows): for c in range(rows): if r%3 == 1 and c%3 == 1: color = brown; grid[r][c] = 1; else: color = white; grid[r][c] = 0; pygame.draw.rect(screen, color, [(margin+width)*c+margin, (margin+height)*r+margin, width, height]) pygame.display.flip(); Now how do I put images of buildings in those brown colored grids at those specific locations? I've tried some of the samples online but can't seem to get them to work. Any help is appreciated. If anyone have a good source for free sprites that I can use for pygame, please let me know. Thanks!

• Getting Line Numbers for Errors Thrown in SQL Server CLR Runtime

  - by fetucine53

  Hi all, I've created a CLR stored procedure that I'm running on SQL 2k5 and I'm wondering if there's any way to get line numbers for exceptions thrown by the .NET code. When an Exception is thrown, I get something along the lines of Msg 6522, Level 16, State 1, Procedure myProcedure, Line 0 A .NET Framework error occurred during execution of user-defined routine or aggregate "myProcedure": System.Exception: testing exception System.Exception: at DummyDLL.myProcedure (String dummyInput) . Is there some way I can load the assembly to give me specific line numbers rather than just the function in which the error was thrown? The assembly itself was compiled with a .pdb, but SQL 2k5 doesn't appear to be reading it in when I load the assembly initially. Thanks!

• Clustering [assessment] algorithm with distance matrix as an input

  - by Max

  Can anyone suggest some clustering algorithm which can work with distance matrix as an input? Or the algorithm which can assess the "goodness" of the clustering also based on the distance matrix? At this moment I'm using a modification of Kruskal's algorithm (http://en.wikipedia.org/wiki/Kruskal%27s_algorithm) to split data into two clusters. It has a problem though. When the data has no distinct clusters the algorithm will still create two clusters with one cluster containing one element and the other containing all the rest. In this case I would rather have one cluster containing all the elements and another one which is empty. Are there any algorithms which are capable of doing this type of clustering? Are there any algorithms which can estimate how well the clustering was done or even better how many clusters are there in the data? The algorithms should work only with distance(similarity) matrices as an input.

• Override delete behaviour in NHibernate

  - by David

  Hi all In my application users cannot truly delete records. Rather, the record's Deleted field gets set to 1, which hides it from selects. I need to maintain this behaviour and I'm looking into whether NHibernate is appropriate for my app. Can I override NHibnernate's delete behaviour so that instead of issuing DELETE statements, it issues UPDATES, as described above? I would obviously also need to override its SELECT behaviour to include the 'AND Deleted = 0' clause. Or read from a view instead. I dunno. TIA for your advice. David

• Regular expression replace in PL/pgSQL

  - by dreamlax

  If I have the following input (excluding quotes): "The ancestral territorial imperatives of the trumpeter swan" How can I collapse all multiple spaces to a single space so that the input is transformed to: "The ancestral territorial imperatives of the trumpeter swan" This is going to be used in a trigger function on insert/update (which already trims leading/trailing spaces). Currently, it raises an exception if the input contains multiple adjacent spaces, but I would rather it simply transforms it into something valid before inserting. What is the best approach? I can't seem to find a regular-expression replace function for PL/pgSQL. There is a text_replace function, but this will only collapse at most two spaces down to one (meaning three consecutive spaces will collapse to two). Calling this function over and over is not ideal.

• Sys undefined for HTTPS url in IE8

  I just discovered a rather peculiar issue in IE8 for a HTTPS link. Every time the page tries to access the HTTPS link, it produces an error. This happens only in IE8 and nothing else. Any idea what's going on? I found some items that said that means the files were not loaded, hence the issue and tried some fixes recommended, but they haven't worked so far. This is a .NET site by the way. https://www.beckshoes.com/cart/cart.aspx Message: 'Sys' is undefined Line: 70 Char: 1 Code: 0 URI: https://www.beckshoes.com/cart/cart.aspx Message: 'Sys' is undefined Line: 319 Char: 1 Code: 0 URI: https://www.beckshoes.com/cart/cart.aspx
