  • Why do WCF clients depend on the app.config file?

    - by routeNpingme
    Like a lot of things, I'm sure there's a good reason for this, so please help me understand... Why, by default, do WCF services store settings in app.config? This has been so frustrating trying to work with multiple Silverlight class libraries. These class libraries are supposed to be completely independent from each other, and this dependency on the app.config seems to cause the following headaches: Single Responsibility Principle - I should be able to add a reference to a class library and go. If that class library uses a service reference, this idea is shot before I even start coding against it. Muddy Configuration - To get other libraries to work, I have to copy and paste the service configurations into the "main" application configs. If an endpoint changes in any way, I can't just worry about a new version of that class DLL - I have to worry about anything that uses it, too. Complex Alternatives - Programmatically creating the endpoint isn't pretty. Period. There has to be a better way. Why doesn't WCF at least separate the service configurations into a ServiceName.config or something that gets copied to an output directory. What am I missing? How do you deal with this?

  • UNIX find for finding file names NOT ending in specific extensions?

    - by Cristi Diaconescu
    Is there a simple way to recursively find all files in a directory hierarchy, that do not end in a list of extensions? E.g. all files that are not *.dll or *.exe UNIX/GNU find, powerful as it is, doesn't seem to have an exclude mode (or I'm missing it), and I've always found it hard to use regular expressions to find things that don't match a particular expression. I'm in a Windows environment (using the GnuWin32 port of most GNU tools), so I'm equally open for Windows-only solutions.

  • jquery $(window).width() and $(window).height() return different values when viewport has not been r

    - by Manca Weeks
    I am writing a site using jquery that repeatedly repeatedly calls $(window).width() and $(window).height() to position and size elements based on the viewport size... In troubleshooting I discovered that I am getting slightly different viewport size reports in repeated calls to the above jquery functions when the viewport is not resized... Wondering if there is any special case anyone knows of when this happens, or if this is just the way it is. The difference in sizes reported are 20px or less, it appears. It happens in Safari 4.0.4, Firefox 3.6.2 and Chrome 5.0.342.7 beta on Mac OS X 10.6.2... I didn't test other browsers yet because it doesn't appear to be specific to the browser. I was also unable to figure out what the difference depends upon - if it isn't the viewport size, could there be another factor that makes the results differ? Any insight would be appreciated... Thanks MAnca

    Hi. I have a "news" page that belongs to a company. All news have a header, detail and html page and they come from database. So i have to print those html pages in a repeater on my "news.aspx". But i couldnt write dynamically. How can i do it or is there anyway else? <asp:Repeater ID="news" runat="server" OnItemDataBound="news_OnItemDataBound"> <ItemTemplate> <asp:HiddenField ID="newsid" runat="server" Value='<%#DataBinder.Eval(Container.DataItem,"newsid") %>' /> <tr> <td class="haberler-sayfasi-habermetni" style="width:580px;padding-bottom:30px;"> <h1 class="haberler-sayfasi-haberbasligi" style="background-image:url(images/haber-ikon.jpg); background-repeat:no-repeat;padding-left:25px;"> <%#DataBinder.Eval(Container.DataItem,"newsheader") %>/h1> <br /> <%#DataBinder.Eval(Container.DataItem,"newsspot") %> <br /><br /> <% **Response.WriteFile('dynamical filename with path');** %> </td> </tr> </ItemTemplate> </asp:Repeater>

  • In iPhone OS, what UTI represents a plain ol' text file?

    - by Justin Searls
    I'm attempting to make use of the UIDocumentInteractionController mechanism in iPhone OS 3.2, but I'm struggling to figure out exactly how to construct a UTI that it likes. I've gotten as far as attempting to set "public.plain-text", but it's hard to test whether this is the correct UTI for a plain text document, since I can't tell whether the issue is that my iPad doesn't have any apps that support plain text import. (I figured Pages would, but I suppose perhaps not, since it will attempt and fail to load any files with the extension .pages, regardless of UTI). Any seasoned OS X developers that can help on this?

  • Automatically copy files without overwriting, but creating numbered ones instead

    - by user1688322
    I need to copy files at a regular interval, eg once an hour so I tried setting up an xcopy batch saying it should copy the files it needs to copy to another folder. Now when it copies, it overwrites the files which is not what it is supposed to do. When a file is copied, it should create a new file instead, named something like File.txt, File-COPY1.txt, File-COPY2.txt or something like that. Any way to do that? Thanks in advance.

  • Formula for producing a CGRect for a UIScrollView, that displays a UIImage in scaled to fit way

    - by RickiG
    Hi I am loading in images with varying sizes and putting them in UIScrollViews, all the images are larger than the UIScrollView. The user can scroll and zoom as they please, but initially I would like for the image to be centered and scaled so the largest side of the image aligns with the edge of the scrollView, i.e. if the picture is in landscape I would like to size and scale it so that the left and right side goes all the way to the edge of the UIScrollVIew and vice versa I found a formula in a utility function in the Programming guide but it does not quite fit my needs. My approach is to use: CGrect initialPos = ? [self.scrollView zoomToRect:initialPos animated:YES]; I know the size of my scrollView and the size of my image, what I need to figure out is the scale and CGRect to apply to the scrollView to center and size my image. Hope someone can help out:) Thanks

  • Simple XNA 2D demo: why is my F# version slower than C# version?

    - by Den
    When running this XNA application it should display a rotated rectangle that moves from top-left corner to bottom-right corner. It looks like my F# version is noticeably much slower. It seems that the Draw method skips a lot of frames. I am using VS 2012 RC, XNA 4.0, .NET 4.5, F# 3.0. I am trying to make it as functional as possible. What could be the reason for poor performance?

  • Is there a way to iterate over all open windows in Mac OS X?

    - by Alex
    When you unplug an external monitor with a higher resolution that your macbook from your laptop, the windows mostly retain their width, but their size gets clipped to the (smaller) height of the macbook screen. When you plug the monitor back in, their size remains frustratingly small. My question is: is there any way that I can iterate over all open windows, save their size, and restore them once the monitor gets plugged in again?

  • Handling bugs, quirks, or annoyances in vendor-supplied headers

    - by supercat
    If the header file supplied by a vendor of something with whom one's code must interact is deficient in some way, in what cases is it better to: Work around the header's deficiencies in the main code Copy the header file to the local project and fix it Fix the header file in the spot where it's stored as a vendor-supplied tool Fix the header file in the central spot, but also make a local copy and try to always have the two match Do something else As an example, the header file supplied by ST Micro for the STM320LF series contains the lines: typedef struct { __IO uint32_t MODER; __IO uint16_t OTYPER; uint16_t RESERVED0; .... __IO uint16_t BSRRL; /* BSRR register is split to 2 * 16-bit fields BSRRL */ __IO uint16_t BSRRH; /* BSRR register is split to 2 * 16-bit fields BSRRH */ .... } GPIO_TypeDef; In the hardware, and in the hardware documentation, BSRR is described as a single 32-bit register. About 98% of the time one wants to write to BSRR, one will only be interested in writing the upper half or the lower half; it is thus convenient to be able to use BSSRH and BSSRL as a means of writing half the register. On the other hand, there are occasions when it is necessary that the entire 32-bit register be written as a single atomic operation. The "optimal" way to write it (setting aside white-spacing issues) would be: typedef struct { __IO uint32_t MODER; __IO uint16_t OTYPER; uint16_t RESERVED0; .... union // Allow BSRR access as 32-bit register or two 16-bit registers { __IO uint32_t BSRR; // 32-bit BSSR register as a whole struct { __IO uint16_t BSRRL, BSRRH; };// Two 16-bit parts }; .... } GPIO_TypeDef; If the struct were defined that way, code could use BSRR when necessary to write all 32 bits, or BSRRH/BSRRL when writing 16 bits. Given that the header isn't that way, would better practice be to use the header as-is, but apply an icky typecast in the main code writing what would be idiomatically written as thePort->BSRR = 0x12345678; as *((uint32_t)&(thePort->BSSRH)) = 0x12345678;, or would be be better to use a patched header file? If the latter, where should the patched file me stored and how should it be managed?
