  • Automate Google Chrome extension installation

    - by gtaborga
    Hi everyone, I am working on creating a Google Chrome extension. We have it included in an automated build system and since it is constantly being worked on we need a solution to be able to package the extension as a .crx file which according to http://code.google.com/chrome/extensions/packaging.html can easily be scripted. My question is after packaging the extension is there a known method either through the command-line or some other programmatic way, to install the newly packaged extension in an automated manner? If someone knows how or has any reference material that I can be pointed towards I would greatly appreciate any help that is offered. Thank you.

  • Error LNK1223 on ARM builds

    - by Seva Alekseyev
    eMbedded Visual C++ 3 project, building for PocketPC 2000. On the ARM build, the linker throws the following error: fatal error LNK1223: invalid or corrupt file: file contains invalid pdata contributions On SH3, the project compiles, links, and works. The project also works when built for ARM on Visual C++ 2005, but I need to test builds specifically from eVC3. Any ideas, please? What's a pdata contribution and how do I affect (or disable) those? It's something to do with exception handling; I've tried disabling SEH by specifying /EHsc, to no effect.

  • Where is PostSharp.Public 1.5 DLL ?

    - by jfneis
    Fellows, I'm going crazy with looks like a really stupid problem. I'm trying to build a simple example using PostSharp as a log AOP utility. I've not installed PostSharp, and I don't want to, I want to reference the necessaries DLLs, change my .csproj and see everything working. Change the project and add references was kind of easy, byt just after adding the LogAttribute to a method I got two errors: Error 1 'Log4PostSharp.LogAttribute' is not an attribute class C:\Dev\LogWithPostsharp\LogWithPostsharpCmd\Program.cs 17 10 LogWithPostsharpCmd Error 2 The type 'PostSharp.Extensibility.MulticastAttribute' is defined in an assembly that is not referenced. You must add a reference to assembly 'PostSharp.Public, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b13fd38b8f9c99d7'. C:\Dev\LogWithPostsharp\LogWithPostsharpCmd\Program.cs 18 22 LogWithPostsharpCmd The first error really looks like consequence of the second, but here is the deal: the PostSharp.Public.* simply doesn't exist in the downloaded .zip. Is there something that I'm not getting? Thank you in advance. Filipe

  • Django auth without "auth_*" tables

    - by Travis Jensen
    We would like to use our own tables for user management instead of the Django "auth" tables. We already have database tables that include all of the relevant information our application needs but it isn't in the Django format. We would prefer not to have the information duplicated in two tables. We would like to utilize the auth package, though, as there is some very nice functionality that we don't want to replicate. I realize we could build our own auth backend, but that doesn't, as far as I can tell, remove the need for two sets of tables in this case. Am I correct in assuming that we cannot do this? I have found no docs that discuss how to modify the underlying model that the auth package is using. The backend simply pre-populates the user object that would eventually be saved in the auth tables. Thanks!

  • How can I use the SSRS ReportViewer from VS 2008 in a VS2010 project?

    - by Adrian Grigore
    Hi, I'm working on an ASP.NET MVC 2 / .NET 3.5 project which includes SSRS 2008 reports. After migrating to VS 2010 RC, the new web forms report viewer has been giving so much trouble that I'd like to use the old report viewer from VS 2008 again. Now I'm just wondering what would be the easiest way to do that. The report viewer is embedded in a Webforms ASPX file which is loaded in an IFrame by the the MVC view. Report parameters are currently stored as session variables, and for security reasons I would prefer not to change that for HTTP POST or GET parameters. So I can't just put the report viewer in a separate application and build that with VS2008. Moving the entire project back to VS 2008 is not an option. So, what's the easiest way for me to use the VS 2008 ReportViewer in VS 2010? Is there way to grab an assembly from VS 2008 and use that in my project? Thanks, Adrian

  • Firefox extension that overlays persistent iFrame?

    - by Crashalot
    Is it possible to build a Firefox extension that displays a floating, persistent iFrame over the page content? I know it's possible to add iFrames using XUL. For instance, you can add an iFrame to a persistent sidebar. However, I want the iFrame to float over the page content, not cause the content to shrink. So far, my only option is to add the iFrame to the DOM, then use CSS "fixed" positioning to float the iFrame. The iFrame must also persist across page loads, exactly as the sidebar does. Adding an iFrame to the DOM, unfortunately, causes the iFrame to vanish when the browser renders a new page (e.g., after clicking a link). Any clues? Thanks!

  • Django pagination | get current index of paginated item in page index, (not the page index range its

    - by cka
    I am trying to build a photo gallery with Django. It is set up by category. I have paginated the results of a category by n amount of images per page. I want to also use the paginator on the page that shows just the single image and have a prev/next button for the prev/next image in that category. My thought was to get the current index for the image itself and have that be the link to the /category/CUR_IMG_ID_PAGINATION_LIST/ as the result of paginating the entire set would yield the same index as the current image index in the paginated results. For instance if the image i want is image 45 out of 150 images total for a category, then when i paginate the 150 images the 45 will be the actual number of the page I want. If there's an easier way to do this, let me know. Django 1.1

  • Ext JS how to tell PagingToolbar to use parent Grid storage?

    - by Nazariy
    I'm trying to build application that use single config passed by server as non native JSON (can contain functions). Everything works fine so far but I'm curious why PagingToolbar does not have an option to use parent Grid store? I have tried to set store in my config like this, but without success: {... store:Ext.StoreMgr.lookup('unique_store_id') } Is there any way to do so without writing tons of javascript for each view defining store, grid and other items in my application or at least extend functionality of PaginationToolbar that use options from parent object? UPDATED, Here is short example of server response (minified) { "xtype":"viewport", "layout":"border", "renderTo":Ext.getBody(), "autoShow":true, "id":"mainFrame", "defaults":{"split":true,"useSplitTips":true}, "items":[ {"region":"center", "xtype":"panel", "layout":"fit", "id":"content-area", "items":{ "id":"manager-panel", "region":"center", "xtype":"tabpanel", "activeItem":0, "items":[ { "xtype":"grid", "id":"domain-grid", "title":"Manage Domains", "store":{ "xtype":"arraystore", "id":"domain-store", "fields":[...], "autoLoad":{"params":{"controller":"domain","view":"store"}}, "url":"index.php" }, "tbar":[...], "bbar":{ "xtype":"paging", "id":"domain-paging-toolbar", "store":Ext.StoreMgr.lookup('domain-store') }, "columns":[...], "selModel":new Ext.grid.RowSelectionModel({singleSelect:true}), "stripeRows":true, "height":350, "loadMask":true, "listeners":{ "cellclick":activateDisabledButtons } } ] }, } ] }

  • Clip UITableView Cell's Separator

    I've been trying to build a view that looks similar to the "stocks" application (surprise). What I would like is to have the scroller bar outside of my rounded table view, shown in the image link below, but clip the cell separators. You can see how they overlap the scroller bar, which is annoying. I can't figure out how Apple put the scroller bar in a spot that looks like it is outside their table. Any ideas?

  • Building TimeZone object in Java

    - by Harish
    I build a Java TimeZone object using the TimeZone String like GMT-8,GMT,PST,EST etc. This did not consider whether the timezone is daylight saving enabled or not.Now there is a requirement to include this check and instead of giving the input as PDT or EDT the daylight saving is given as a seperate flag.I am not sure whether TimeZone has a direct method to change the dayLight saving property of that TimeZone. So if I get an input like PST and DaylightSaving as true then I have to change the string as PDT.Whats even worse is sometimes I will get inputs like GMT-8 or GMT-6 with Day light flag as either true or false. Is there a way out ? I can't use thirdparty TimeZone related classes Code Sample: TimeZone timeZone = TimeZone.getTimeZone("EST"); TimeZone timeZone = TimeZone.getTimeZone("PST"); TimeZone timeZone = TimeZone.getTimeZone("GMT-8");

  • Objective-C "miscasting" a string/int using stringWithFormat and %d

    - by user141146
    Hi, I think this is a relatively simple question, but I don't precisely know what's happening. I have a method that tries to build a string using NSString's stringWithFormat It looks like this: NSString *line1 = [NSString stringWithFormat:@"the car is %d miles away", self.ma]; In the above line "self.ma" should be an int, but in my case, I made an error and "self.ma" actually points to a NSString. So, I understand that the line should read NSString *line1 = [NSString stringWithFormat:@"the car is %@ miles away", self.ma]; but my question is what is the %d in the first example doing to my NSString? If I use the debugger, I can see that in once case, "self.ma" equals "32444", but somehow the %d converts it to 1255296. I would've guessed that the conversion of 32444 = 1255296 is some type of base-numbering conversion (hex to dec or something), but that doesn't appear to be the case. Any idea as to what %d is doing to my string? TIA

  • Creating a user-defined code generation system in PHP

    - by user270766
    My newest project that I'm looking to build with CodeIgniter would require some sort of system that would allow a user to drag and drop pre-defined functions/methods into mini-classes/objects and then run/test them in the browser. So it'd something similar to Scratch. I've designed a relational database that I think could work for this (storing the function names and have these classes "subscribe" to those functions) - but I'm wondering whether or not to go ahead with it. Is there a better way to do this or is there a system out there that would accomplish this for me? EDIT: It would have to be extremely simple for an end user, but hopefully be flexible enough to easily add more complex functionality in the future.

  • Developing Installer Packages, are Visual Studio Setup Projects suitable for complex setups

    - by Robert
    Are "Visual Studio Setup" Projects suitable for complex setups in different versions? The application is rather large ( 500.000 lines of code) and is under continuous development. Every 6 to 10 month a new version gets released. We have multiple configuration files (INI and XML), registry keys, database migration scripts, etc. The application is in the progress of being migrated from VB6 to .NET . The old installer was build with Installshield. The feedback to Installshield is: Bad adaptability, bad reuse - thats way we are evaluating "Visual Studio Setup" as an alternative. Other products we consider: Free Solutions WiX NSIS Commercial Solutions Installshield (again..) Wise Advanced Installer sth. missing?

  • What's wrong with the analogy between software and building construction?

    - by kuosan
    Many people like to think of building software as constructing a building so we have terms like building blocks and architecture. However, lately I've been to a couple of talks and most people say this analogy is wrong especially around the idea of having a non-coding software architect in a project. In my experience, good software architects are those who also write code so they won't design things that only looks good on paper. I've worked with several Architecture Astronauts, who have either limited or outdated experience in programming. These architecture astronauts quite often missed out critical details in their design and cause more harm than good in a project. This makes me wonder what are the differences between constructing a software and a building? How come in the building industry they can have architects who probably never build a house in their life and purely handles design work but not in the software development field?

  • Freeware Programmer Calculator

    - by AdamC
    There have been lots of times in the past where a good programmer-oriented calculator would've saved me a lot of time. Lately, I've been doing quite a lot of bit manipulation, and having to do build/run to debug my calculations feels really slow. I've looked for something like this in the past, but found nothing that worked very well. The only thing that comes close is this one from AnalogX, but I can't get it to work or really do anything on my vista box which is where I'm doing most of my work at the moment. (btw - please send comments about my vista usage here;). Anyway, I'm looking for something for simple calculations using a C-like syntax with support for proper precenedce, operators, etc. Bonus points for cross-platform. The python interpreter was a great idea and is totally cross-platform. For windows only SpeQ is amazing. Thanks for the suggestions.

  • IText Lines Per Page?

In this new scenario, I have N words of ASCII text that I need to add as text pages to a new PDF. Each page should be 8.5 x 11, .5 margins, using some monospaced font. Is IText(Sharp) smart enough to automatically apply line and page breaks where necessary or do I need to do this manually? Are their any good IText tutorials for this scenario? thanks! scottm

  • Is there a 2d sprite library for webgl?

    - by Devon
    I am looking to build a 2d game using WebGL. I want the hardware acceleration that WebGL provides and I cannot get this from the 2D canvas context in the canvas tag. With that said, is there a tutorial on creating 2D sprites using webGL? Or, better yet, is there a 2D sprite library for WebGL? Ideally, I'm looking for something like cocos2d ported to WebGL. Not surprisingly, all of the demos, tutorials and libraries I have found for WebGL focus on 3D manipulation. Are there any WebGL libraries that support 2D sprites?

  • Common lisp error: "should be lambda expression"

    - by Zachary
    I just started learning Common Lisp a few days ago, and I'm trying to build a function that inserts a number into a tree. I'm getting an error, * - SYSTEM::%EXPAND-FORM: (CONS NIL LST) should be a lambda expression From googling around, it seems like this happens when you have too many sets of parenthesis, but after looking at this for an hour or so and changing things around, I can't figure out where I could be doing this. This is the code where it's happening: (defun insert (lst probe) (cond ((null lst) (cons probe lst)) ((equal (length lst) 1) (if (<= probe (first lst)) (cons probe lst) (append lst (list probe)))) ((equal (length lst) 2) ((cons nil lst) (append lst nil) (insertat nil lst 3) (cond ((<= probe (second lst)) (insert (first lst) probe)) ((> probe (fourth lst)) (insert (fifth lst) probe)) (t (insert (third lst) probe))))))) I'm pretty sure it's occurring after the ((equal (length lst) 2), where the idea is to insert an empty list into the existing list, then append an empty list onto the end, then insert an empty list into the middle.

  • Why does Xcode launch the iPhone simulator when the iPad simulator is selected?

    - by Dr Dork
    When I open an existing iPad project in Xcode and "Build and Run" it, it launches the iPhone simulator when I have the iPad Simulator set as the active executable? Inside the iPhone simulator is a shrunken version of the iPad. What is going on? How do I get it to run the iPad simulator? Note: When the iPhone Simulator is running, I double checked the Hardware-Device setting and it's set to iPad. This is what I want, of course, but I don't want it to run the iPhone simulator. I seem to recall it used to run an iPad simulator. Is there such a thing or am I tripping and there is only an iPhone simulator that can run iPad apps? Thanks in advance for your help!

  • UIImages not displaying in TableView on iPhone, but working in Simulator

    - by Graeme
    Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. It's just a blank white space. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }

  • Where is sdl-config installed on MacOS 10.6 (Snow Leopard)

    - by jmglov
    After installing SDL and SDL-devel in MacOS X 10.6 (Snow Leopard), trying to configure some source code that requires SDL yields: checking for sdl-config... no checking for SDL - version >= 1.2.0... no *** The sdl-config script installed by SDL could not be found *** If SDL was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the SDL_CONFIG environment variable to the *** full path to sdl-config. configure: error: *** SDL version 1.2.0 not found! Does anyone know where to find sdl-config? I guess I can build SDL from source, but why should I have to, when there exist pre-built packages?

  • Is it easier to write a recursive-descent parser using an EBNF or a BNF?

    - by Vivin Paliath
    I've got a BNF and EBNF for a grammar. The BNF is obviously more verbose. I have a fairly good idea as far as using the BNF to build a recursive-descent parser; there are many resources for this. I am having trouble finding resources to convert an EBNF to a recursive-descent parser. Is this because it's more difficult? I recall from my CS theory classes that we went over EBNFs, but we didn't go over converting them into a recursive-descent parser. We did go over converting BNF's into a recursive-descent parser. The reason I'm asking is because the EBNF is more compact. From looking at the EBNF's in general, I notice that terms enclosed between { and } can be converted into a while loop. Are there any other guidelines or rules?
