• Centralised/shared COM DLL, possible?

  - by vikp

  Hi, We have a system that makes a use of 3rd party COM DLL written in vba We have a centralised web application and 1-50 client machines that must reference that COM DLL in order to use our centralised web application. The COM DLL is going to be updated rapidly in the future, which means that it has to be re-installed on every machine manually. Is it possible to centralise this COM DLL somwhere on the network? Is there any other alternatives? Otherwise the maintenance overhead will be huge... Thank you

• How to detect the language of MS Excel from C#

  - by Babba

  If i try to use Excel from C# (interop) i receive error (HRESULT: 0x80028018) when current thread language is different from Excel language: so i need to set thread language, they must be the same. Which is the best method to understand the language of Excel/Office? 1) registry (HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\LanguageResources\UILanguage ? How understand wich version (12.0/14.0/...?) 2) with Application like suggested here (http://stackoverflow.com/questions/2804556/how-to-detect-the-language-of-ms-excel) ? It's ok but i need a strong reference to a specific version Microsoft.Office.Core and so i can't do it for different versione of Office: Excel.Application application = new Excel.Application(); int iUi = application.LanguageSettings.get_LanguageID(Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI); MessageBox.Show(iUi.ToString()); 3) other?

• After adding a UILabel to my view, how do I delete it?

  - by Travis

  I have added a UILabel to my view programmatically like this: myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 30.0f)]; myLabel.center = CGPointMake(160.0f, 120.0f); myLabel.backgroundColor = [UIColor clearColor]; myLabel.textColor = [UIColor whiteColor]; myLabel.font = [UIFont fontWithName:@"Helvetica" size: 18.0]; myLabel.textAlignment = UITextAlignmentCenter; myLabel.text = @"Hello"; [self.myView addSubview:myLabel]; To add a label to my view. What I can't seem to find out is once I'm done w/ the label (at a future point) how can I delete it from the view? [myLabel release] doesn't seem to work which I think makes sense because the view it's added to probably retained it's over reference. So what is the best practice?

• Smoothing Small Data Set With Second Order Quadratic Curve

  - by Rev316

  I'm doing some specific signal analysis, and I am in need of a method that would smooth out a given bell-shaped distribution curve. A running average approach isn't producing the results I desire. I want to keep the min/max, and general shape of my fitted curve intact, but resolve the inconsistencies in sampling. In short: if given a set of data that models a simple quadratic curve, what statistical smoothing method would you recommend? If possible, please reference an implementation, library, or framework. Thanks SO!

• How to implement Cocoa copyWithZone on derived object in MonoMac C#?

  - by Justin Aquadro

  I'm currently porting a small Winforms-based .NET application to use a native Mac front-end with MonoMac. The application has a TreeControl with icons and text, which does not exist out of the box in Cocoa. So far, I've ported almost all of the ImageAndTextCell code in Apple's DragNDrop example: https://developer.apple.com/library/mac/#samplecode/DragNDropOutlineView/Listings/ImageAndTextCell_m.html#//apple_ref/doc/uid/DTS40008831-ImageAndTextCell_m-DontLinkElementID_6, which is assigned to an NSOutlineView as a custom cell. It seems to be working almost perfectly, except that I have not figured out how to properly port the copyWithZone method. Unfortunately, this means the internal copies that NSOutlineView is making do not have the image field, and it leads to the images briefly vanishing during expand and collapse operations. The objective-c code in question is: - (id)copyWithZone:(NSZone *)zone { ImageAndTextCell *cell = (ImageAndTextCell *)[super copyWithZone:zone]; // The image ivar will be directly copied; we need to retain or copy it. cell->image = [image retain]; return cell; } The first line is what's tripping me up, as MonoMac does not expose a copyWithZone method, and I don't know how to otherwise call it. Update Based on current answers and additional research and testing, I've come up with a variety of models for copying an object. static List<ImageAndTextCell> _refPool = new List<ImageAndTextCell>(); // Method 1 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 2 [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); return cell; } [Export("dealloc")] public void Dealloc () { _refPool.Remove(this); this.Dispose(); } // Method 3 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 4 static IntPtr selRetain = Selector.GetHandle ("retain"); static IntPtr selRetainCount = Selector.GetHandle("retainCount"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone (IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell () { Title = Title, Image = Image, }; _refPool.Add (cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } public void PeriodicCleanup () { List<ImageAndTextCell> markedForDelete = new List<ImageAndTextCell> (); foreach (ImageAndTextCell cell in _refPool) { uint count = Messaging.UInt32_objc_msgSend (cell.Handle, selRetainCount); if (count == 1) markedForDelete.Add (cell); } foreach (ImageAndTextCell cell in markedForDelete) { _refPool.Remove (cell); cell.Dispose (); } } // Method 5 static IntPtr selCopyWithZone = Selector.GetHandle("copyWithZone:"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { IntPtr copyHandle = Messaging.IntPtr_objc_msgSendSuper_IntPtr(SuperHandle, selCopyWithZone, zone); ImageAndTextCell cell = new ImageAndTextCell(copyHandle) { Image = Image, }; _refPool.Add(cell); return cell; } Method 1: Increases the retain count of the unmanaged object. The unmanaged object will persist persist forever (I think? dealloc never called), and the managed object will be harvested early. Seems to be lose-lose all-around, but runs in practice. Method 2: Saves a reference of the managed object. The unmanaged object is left alone, and dealloc appears to be invoked at a reasonable time by the caller. At this point the managed object is released and disposed. This seems reasonable, but on the downside the base type's dealloc won't be run (I think?) Method 3: Increases the retain count and saves a reference. Unmanaged and managed objects leak forever. Method 4: Extends Method 3 by adding a cleanup function that is run periodically (e.g. during Init of each new ImageAndTextCell object). The cleanup function checks the retain counts of the stored objects. A retain count of 1 means the caller has released it, so we should as well. Should eliminate leaking in theory. Method 5: Attempt to invoke the copyWithZone method on the base type, and then construct a new ImageAndTextView object with the resulting handle. Seems to do the right thing (the base data is cloned). Internally, NSObject bumps the retain count on objects constructed like this, so we also use the PeriodicCleanup function to release these objects when they're no longer used. Based on the above, I believe Method 5 is the best approach since it should be the only one that results in a truly correct copy of the base type data, but I don't know if the approach is inherently dangerous (I am also making some assumptions about the underlying implementation of NSObject). So far nothing bad has happened "yet", but if anyone is able to vet my analysis then I would be more confident going forward.

• Google Local Search API

  - by Gublooo

  hey guys couple of quick questions 1) In the local search results - we can get a lot of parameters like street title, address, city, state, lat, long , url etc - In order for me to uniquely identify this record - can I consider URL to be unique to this address or concatenation of latitude and longitude Ref: http://code.google.com/apis/ajaxsearch/documentation/reference.html#_class_GlocalResult 2) In terms of usage, depending upon what user enters, I'm displaying a list of local business for the user to choose. Now when a user selects a particular business address - is it legal for me to store that business address along with lat and longitude information in my database for future look ups. I've seen a lot of blogs talking about storing the lat/long info but just want to be sure that i'm not violating and google rules. Thanks

• Cmake suddenly can't find my source files anymore...

  - by aheld

  To make a long story short: To add insult to injury, CMake actually ran fine several times. I was wrestling with a compiler error when CMake suddenly didn't feel like working anymore. For reference, here's the whole CMakeLists.txt file: set(CMAKE_INCLUDE_CURRENT_DIR ON) Find_Package ( SDL REQUIRED ) Find_Package ( SDL_image REQUIRED ) Find_Package ( SDL_mixer REQUIRED ) if ( NOT SDL_FOUND ) message ( FATAL_ERROR "Make sure that SDL is installed" ) endif ( NOT SDL_FOUND ) link_libraries ( ${SDL_LIBRARY} ${SDLIMAGE_LIBRARY} ${SDLMIXER_LIBRARY} SDLmain ) set(wiggle_SOURCES level.cpp levelgenerator.cpp main.cpp player.cpp scoreboard.cpp snake.cpp soundplayer.cpp titlescreen.cpp ) add_executable(Wiggle ../${wiggle_SOURCES}) The error occured for the first time when, instead of simply typing "make", I typed "make -lSDL -lSDL_image -lSDL_mixer" - make refused to find the header files SDL.h and SDL_image.h after I detached the project from Code::Blocks.

• MSSQL Search Proper Names Full Text Index vs LIKE + SOUNDEX

  - by Matthew Talbert

  I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using MS SQL 2008 currently.

• Google app engine - what is the lifecycle of PersistenceManager?

  - by Domchi

  What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

• Change input text to regular text on blur and ability to edit jQuery

  - by eknown

  I'm creating a form where I'm eliminating the use of a save button. The form is made up of input text boxes and textareas. After the user enters data into the input field, I want to trigger an onBlur function and change the input into a span that contains the information that the user entered. I also want to have the ability to edit this information, so if the user clicks on the newly created span with text, it will turn back into the input field with the current information for their editing pleasure. For reference, I'm looking to have a functionality pretty much like on editing a photo title on Flickr. If possible, I'd also like to have the textbox show "saving..." for half a second after the blur to reflect interaction with server.

• Mathematica Plot3D does not produce a plot when graphing a user-defined function?

  - by pythonscript

  I'm writing a simple Mathematica implementation of the black-scholes model and using Plot3D to plot the pricing surface. However, when I run this code, no plot is produced. My call and put functions to produce correct values when run separately, but no plot is produced. Code: Clear[d1, d2, call, put, stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] d1[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := (Log[stockPrice / strikePrice] + (riskFreeRate + 0.5*volatility^2)*timeToExp) / (volatility * Sqrt[timeToExp]) d2[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] - volatility*Sqrt[timeToExp] call[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := stockPrice * CDF[NormalDistribution[0, 1], d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] - strikePrice * Exp[-riskFreeRate*timeToExp] *CDF[NormalDistribution[0, 1], d2[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] Plot3D[call[stockPrice, 500, 0.0030, timeToExp, 0.39], {stockPrice, 10, 1000}, {timetoExp, 0.0833333, 5}] Other plots, like this sample from the reference, do work. Plot3D[{x^2 + y^2, -x^2 - y^2}, {x, -2, 2}, {y, -2, 2}, RegionFunction -> Function[{x, y, z}, x^2 + y^2 <= 4], BoxRatios -> Automatic]

• Why is the servlet request not available in the portlet API

  - by John Smith

  The portlet API deos not provide any reference to the enclosing servlet request and response objects. I know it is not the preferred model of interaction with the user, but it seems draconian to remove all access. I understand that for portlet driven interaction with the user, you want to use portlet URLs, and let the portlet container manage all the complexity. However if you have a number of portlets which are basically showing variants of the same data, it makes sense for them to be able to use the enclosing request to drive the data. We ended up using using a Liferay specific call to get the request, and it all seems to work as we wish. However I do feel the guilt. So my question really is, is there an underlying deep reason for the prohibition, or is it just to enforce the authors view of the API environment?

• Documentation of a software project

  - by anijhaw

  I am working with a team that works on a very large software project, we have tons of Documentation that is written in MS WORD format with nohyperlinked indexes, no search ability. Everyday we waste our time trying to find the exact document or reference. I was thinking if there was way or even a professional tool that would convert all this into a wiki format and maybe with a little manual (painful) help be organised into something that improves the accessibility. I use Google Desktop Search to make my life a little easier but its not the best solution I just want to know if any of you faced similar problems and possible solutions to this issue.

• Uri for bitmap in subfolder (c# wpf)

  - by the empirical programmer

  I have a wpf app where I'm using an image. To reference the image I use: Uri uri = new Uri("pack://application:,,,/assemblyName;Component/myIcon.png"); BitmapImage(uri) If I add the png directly under the csproj file (with its properties BuildAction=Resource) then it works fine. But I want to move it to a subfolder under the csproj. Another SO question asked about bitmaps\uri's (857732) and an answer linked to this msdn. So I tried : Uri uri = new Uri("pack://application:,,,/assemblyName;Component/Icons/myIcon.png"); But that did not work. Any ideas?

• SVG with external images doesn't load them when embedded with <img> tag in browsers

  - by mat3001

  I made the following observation: If I create an svg image that references an external raster image via "xlink:href" and try to load the svg in browsers, the external images are only shown if I use the tag, but not when using the tag. Rendering with the tag is quite slow and not as clean as using the img tag for images so I was wondering if there's a way to make it work through the tag. At first I thought it doesn't work because of a same origin policy, but even if the referenced image is in the same directory and I reference it through its name only, it wont load. Any ideas?

• Apache rewriteBase in .htaccess for development subdomains

  - by Das123

  I think I'm missing something and don't think I really understand how rewriteBase works. The problem I have is that I have a production site where the site is in the root directory yet I have my development site in a localhost subdirectory. Eg http://www.sitename.com/ vs http://localhost/sitename/ If I have for example an images folder I want to reference the images from the site root by using the initial slash in the href. Eg Using a relative href (without the initial slash) is not an option. This will work on the production site but the development site is looking for http://localhost/images/imagename.jpg instead of http://localhost/sitename/images/imagename.jpg So I thought all I needed to do was setup the following in my .htaccess file to force the site root to my subdomain within the development environment: Options +FollowSymLinks RewriteEngine On RewriteBase /sitename But this still uses localhost as the site root instead of localhost/sitename. Can anyone please give me some pointers?

• Single HTML Table from multiple MySQL tables

  - by David Chouinard

  Hi! I've been struggling for a while with this one; I'll try to explain it here as simply as possible. Consider this MySQL table: +----------+-----------+---------+--------+ |status_id |session_id |pilot_id |present | +----------+-----------+---------+--------+ |1 |61 |901 |1 | |2 |63 |901 |1 | |3 |62 |901 |0 | |4 |62 |902 |1 | |5 |63 |903 |1 | +----------+-----------+---------+--------+ Both session_id and pilot_id are foreign keys making reference to a primary key in another table. The same pilot_id can be associated with different session_id, but every pilot_id-session_id combination is unique. I need to make an HTML table (in PHP) that would display the data like this: +----------+---------+---------+---------+ | |61 |62 |63 | +----------+---------+---------+---------+ |901 |X | |X | |902 | |X | | |903 | | |X | +----------+---------+---------+---------+ Hence, rows are pilot_id and columns are session_id. When a pilot_id-session_id combination has a present value of 1, the corresponding cell should be checked. (ie. when the row-combination is zero or the combination does not exist in the MySQL table, nothing should appear in the HTML table) Phew. Any ideas? Thanks!

• Renaming ICSharpCode.SharpZipLib.dll

  - by John B.

  Hi, well I am having a problem renaming the ICSharpCode.SharpZipLib.dll file to anythig else. I am trying to shorten the file name. I reference the assembly in the project, but when the program reaches the statements where I use the library. It spawns an error that it could not find the assembly or file 'ICSharpCode.SharpZipLib'. When I change the file name back to ICSharpCode.SharpZipLib.dll the application works noramally. So, is there any way to change the file name. Also, am I allowed to change it without violating the license (I am going to use it in a commercial application). Thanks.

• WCF Advanced Books

  - by hgulyan

  Hi, I've read all questions like mine and found a few good links. My question is about architect of WCF, how it is designed, how is generated reference.vb, wsdl and xsd files. How can I do that manually, some good examples of WCF Systems (mostly on desktop applications over TCP). I'd like a book or documentation or anything else, that can give me advanced knowledge of WCF. What do you think of this book http://www.amazon.com/Professional-WCF-Windows-Communication-Foundation/dp/0470563141/ref=sr_1_5?ie=UTF8&s=books&qid=1269425390&sr=8-5 ? And generally is there any source that would give me this all or the only way is practising, trying, looking in all that generated files and reading documentations? Thank you.

• RenderAction in an HtmlHelperExtension Method?

  - by TimLeung

  I am trying to call the RenderAction Extension Method within my own Html Helper: System.Web.Mvc.Html.ChildActionExtensions.RenderAction(helper, "account", "login"); this is so that along with some additional logic, I would like all html helpers to use a common method name structure when calling it on the view: <%= Html.CompanyName().RenderAccount() %> but the problem I am having is that, asp.net will complain about not finding the actual route it needs to process. It does not take in the parameters of "controller" to be used as the action and "login" to be used as the action. It seems to only reference the current route. Any ideas how I can package up the RenderAction?

• MySQL Export with Column Heading

  - by st4nt0n

  Hello - I am very, very, new to mySQL. I've got experience in general technical terms, but not with the syntax or concepts of mySQL. I have been tasked with exporting a table from MySQL into a pipe delimited .txt or .xls that I can use to add 7500 more records to manually, then import back into the table. I tried to use INTO OUTFILE, but I don't get column headings, which I need for reference to merge the new records. Is there a good resource that can explain this to a complete novice? I would usually go down to my bookstore and start learning, but I'm on a bit of a time crunch. Thanks all!

• WCF does not generate the properties

  - by BDotA

  I have a .NET 1.1 ASMX and want to use it in a client WinForms app. If i go wit the old way and add it as a "WebRefrence" method then I will have access to two of its properties which are "url" and "UseDefaultCredentials" and it works fine. But if I go with the new WCF way and add it as a ServiceReference I still have access to the methods of that ASMX but those two properties are missing. what is the reason for that? so for example in the old way ( adding WebReference) these codes are valid: TransferService transferService= new TransferService(); transferService.Url = "http://something.asmx"; transferService.Credentials = System.Net.CredentialCache.DefaultCredentials; string[] machines = transferService.GetMachines(); But in the new way ( adding Service Reference ) using(TransferServiceSoapClient transferServiceSoapClient = new TransferServiceSoapClient("TransferServiceSoap")) { transferServiceSoapClient.Url = "someUrl.asmx"; //Cannot resolve URL transferServiceSoapClient.GetMachines(new GetMachinesRequest()); transferServiceSoapClient.Credentials = .... // //Cannot resolve Credentials }

• Diagonal of polygon is inside or outside?

  - by Himadri

  I have three consecutive points of polygon, say p1,p2,p3. Now I wanted to know whether the orthogonal between p1 and p3 is inside the polygon or outside the polygon. I am doing it by taking three vectors v1,v2 and v3. And the point before the point p1 in polygon say p0. v1 = (p0 - p1) v2 = (p2 - p1) v3 = (p3 - p1) With reference to this question, I am using the method shown in the accepted answer of that question. It is only for counterclockwise. What if my points are clockwise. I am also knowing my whole polygon is clockwise or counterclockwise. And accordingly I select the vectors v1 and v2. But still I am getting some problem. I am showing one case where I am getting problem. This polygon is counterclockwise. and It is starting from the origin of v1 and v2.
