  • Unity setting problem when defined in code

    - by Xabatcha
    I have problem when asking for default ILogger from Unity container. I have this setting defined in code (its VB.net) Dim container As IUnityContainer ... container.RegisterType(Of ILogger, NullLogger)() container.RegisterType(Of ILogger, EntLibLogger)("EL") When I am getting ILogger from container I may have different name, like: Ioc.Resolve(Of ILogger)("MyLogger") However this raises error as the mapping is not set for 'MyLogger'. Can I force container to return type which was registered without name? Actually when I used setting from web.config it worked. Any tips most welcome. Thanks. Cheers, X.

  • WPF Moving Element problem

    - by Kyle
    Hello, I am probably over-doing a very simple problem, but this is what I have a the moment: I have several buttons and a listbox of items in which the user can select and interact with. My application also moves those elements in accordance to the application width/height, such as follows: listBox1.Margin = new Thickness(this.ActualWidth * 0.84, this.ActualHeight * 0.3, 0, 0); I am able to select the items within the listbox and click on buttons appropriately while in windowed mode, but as I begin to stretch the application larger, I try to click on the items, and I cannot do so.. is this because I also need to update their hit-detection rectangles as well? Or perhaps am I moving the items incorrectly? I am at a loss.. any information would be very helpful at this point...thanks!

  • Problem with dependencies in m2eclipse

    - by MH
    Hi, I have a problem with m2eclipse and Nexus. Normally, when you create a new Maven Project in Eclipse, you can select an Archetype like maven-archetype-quickstart from the Nexus Indexer. Unfortunately, the Nexus Indexer doesn't show anything at all. But the worst part about all this is, that the "Add Dependency" menue doesn't work. (For a better understanding: By clicking on the "Dependencies" tab, you can usually click on a button in order to enter a groupId or artifactId. That's the menue what I am talking about. If I enter for example "junit", it shows no search results.) Does anybody know this issue? How could I fix it? Thanks a million in advance for any help.

  • Locked visible cells Excel problem

    - by graham.reeds
    I have a problem with an Excel Template in Excel 2007. I need to remove a row from a summary report but the developer who created this report has somehow managed to set it so that only certain number of rows & columns are visible (in case you are interested it is A1:G30) - no headers, no grid, just blue nothingness. Deleting the offending line just peels back the white-ness. I want to change the resolution of the visible grid to A1:G29. I would ask on google but I haven't the foggiest what the tool would be called to do this (if I did I probably wouldn't be asking). Giving generic terms gives very generic results. I've been through every ribbon and came up blank. Help me out my misery - please!

  • Orverride Problem for Custom Design on Product - Magneto

    - by Chris
    I am running several sites in several different languages off of single instance of magneto. There are two main styles Site 1 Site 2 Each site has some cusomtimizations based on language So each shop view has an some templates defined Site 2 - DE Site 2 - UK Now the problem is that when I apply a product level design, it forget's about the language level definition and skips back to the main definition. I want it to work like this Site 2 Site 2 DE Product Style But Instead it seems to work like this Site 2 Site 2 DE Product Style Where Site 2 DE is not ignored because a custom product style has been defined. How can I get the first hierarchy to work? So that my product styles do not override the language styles completely.

    - by Kamiel
    Hi all, I'm experiencing difficulties getting my iframe to display correctly in IE6 & IE7. www.e-g-t.nl I think IE has the height of the iframe stretched to far beyond the 400px height I set it to be, and the content is vertically centered. I'm not an expert at css or html for that matter and don't seem to get it right. In IE8 though, the problem doesn't seem to exist. Any help on this is much appreciated!

  • Problem with Maven in Spring roo

    I was trying to run the Wedding RSVP sample given with Spring Roo 1.0.0.RC3. I am running on Maven 2.2.1 and JDK 1.5.0_19, Java and M2 Home are properly set. Unfortunately none of the commands that involve Maven calls (example: "Perform test" or 'Perform eclipse") work and there is no error either. The cursor immediately returns on the roo command line. I also tried the steps at http://blog.springsource.com/2009/05/27/roo-part-2 but same problem. Did anybody face this issue?

  • Problem loading js content with ajax

    - by Justin Goodman
    I have a page that loads content into a single div via a script in the page. It works fine but the problem is that I have a lightbox in one of the dynamically loaded pages that only works the first time you navigate to it (the script I got for the page loading is found here). Once you navigate to another area, then back again, the lightbox fails to work and instead just loads the plain image. It's been suggested that the easiest way to fix this would be to have a script unload the js and css that is loaded in with the page, then reload it when you go back to the gallery section. I'm a designer, not a developer though, so I don't know if this is true or not. Any help is really appreciated. The page can be found here: justgooddesign.net/graduation/
