  • structuremap configuration change based on settings in app.config

    - by user74825
    I am using structuremap in my project. To inject different implementation of a repository, I want to have a switch in app.config which changes all real implementation of a repository to a mock repositories. Lets say IRepository has two implementations RealRepository and MockRepository ForRequestedType() .TheDefaultIsConcreteType(); I want to have a switch in app.config / web.config say (Mock=1), which changes all real repositories implementation to ForRequestedType() .TheDefaultIsConcreteType(); I don't want to write whole plugin definition in app.config, just want one switch, how do I implement this?

  • Pylons/Routes Did url_for() change within templates?

    - by Charles Merram
    I'm getting an error: GenerationException: url_for could not generate URL. Called with args: () {} from this line of a mako template: <p>Your url is ${h.url_for()}</p> Over in my helpers.py, I do have: from routes import url_for Looking at the Routes-1.12.1-py2.6.egg/routes/util.py, I seem to go wrong about line it calls _screenargs(). This is simple functionality from the Pylons book. What silly thing am I doing wrong? Was there a new url_current()? Where?

  • WPF databinding update comboxbox2 based on selection change in combobox1 with MVVM

    - by cody
    I have a combo box that I have bound to a list that exists in my viewmodel. Now when a users makes a selection in that combo box I want a second combo box to update its content. So, for example, combobox1 is States and combobox2 should contain only the Zipcodes of that state. But in my case I don't have a predefined lists before hand for combobox2, I need to go fetch from a db. Also, if needed, I could get all the potential values for combobox2 (for each combobox1 value) before hand, but I'd like to avoiding that if I can. How do I implement in WPF and using MVVM? I'm fairly new to this whole wpf\databinding\mvvm world.

  • How to change handedness of coordinates?

    - by 742
    How to convert from Euler's coordinates E1 = (x1, y1, z1, yaw1, pitch1, roll1) to E2 = (x2, y2, z2, yaw2, pitch2, roll2) where x, y, z are the coordinates of a point and yaw, pitch, roll the direction/orientation of a vector which origin is the point. yaw is around y, pitch around x, roll around z. They are performed in that order. Yaw 0 is normal to the plan xy (opposite to z in E1 and equal to z in E2). E1 uses a right handed space and E2 a left handed space. Both have the same origin, the same direction for y (top) and z (into the screen). They differ by x which is to the left on E1 and to the right on E2. They also differ by their direction of positive rotations. I've a custom type to hold the scalar representation and to convert from and to the equivalent WPF Matrix3d representation.

  • Java - Google App Engine - InvalidClassException when I change a class that was stored in session sc

    - by Spines
    I updated my User class, and now whenever someone that had the old version of the User class stored in their session scope accesses my site, I get an InvalidClassException. javax.servlet.ServletException: java.lang.RuntimeException: java.io.InvalidClassException: User; local class incompatible: stream classdesc serialVersionUID = 4949038118012519093, local class serialVersionUID = -971500502189813151 How do I stop this error from happening for those users? I could probably invalidate everyone's sessions every time I want to update a class that gets stored in session scope, but is there a better way, so that my user's don't have to login again?

  • How to change rowHeight of a TableViewCell depending on Stringlength

    - by Jens Koehler
    I have a table with different entries, each with different length. The height of each row should fit, so it can show the whole string. I use the following code: //... cellForRowAtIndexPath if (row == 0) { cell = [tableView dequeueReusableCellWithIdentifier:@"affCell"]; //if (!cell) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"affCell"]autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.autoresizingMask = UIViewAutoresizingFlexibleHeight; affL = [[UILabel alloc] initWithFrame:CGRectZero]; affL.textAlignment = UITextAlignmentLeft; affL.autoresizingMask = UIViewAutoresizingFlexibleHeight; [cell.contentView addSubview:affL]; //} //declaration label affL.text = [fDictionary objectForKey:@"aff"]; affL.numberOfLines = 0; [affL sizeToFit]; affL.frame = CGRectMake(15.0, 10.0, 220.0, affL.frame.size.height); CGFloat affLH = affL.frame.size.height; [tableView setRowHeight:affLH+30]; I also use //... heightForRowAtIndexPath return affL.frame.size.height; How can I fix this problem?

  • How do I change JAVASCRIPT_DEFAULT_SOURCES for my application?

    - by Adam Lassek
    When you call javascript_include_tag :defaults you usually get: prototype.js, effects.js, dragdrop.js, and controls.js. These are stored in a constant in ActionView::Helpers::AssetTagHelper called 'JAVASCRIPT_DEFAULT_SOURCES`. My application uses jQuery, so I want to replace the Prototype references with something more useful. I added an initializer with these lines, based on the source code from jRails: ActionView::Helpers::AssetTagHelper::JAVASCRIPT_DEFAULT_SOURCES = %w{ jquery-1.4.min jquery-ui jquery.cookie } ActionView::Helpers::AssetTagHelper::reset_javascript_include_default But when I do this, I get: warning: already initialized constant JAVASCRIPT_DEFAULT_SOURCES during startup. What's the correct way of changing this value? In the source code it checks for the constant before setting it, but apparently that happens before it runs the initializer scripts. The Rails 3.0 release will provide much greater flexibility with choice of JS libraries, so I guess this is a problem with an expiration date.

  • Cannot change the target CPU to x86 Or x64 in Visual Studio 2005

    - by geekzilla
    I am trying to build a website application and specify the target CPU as x86 instead of Any CPU. The only choices I have in Configuration Manager under the "Active solution platform:" drop-down list are: "Any CPU", "Edit..", and "New...". In the "Project Contexts" portion of the "Configuration Manager" window, it lists 3 columns: "Project", "Configuration" and "Platform". Under the "Platform" column, my only choice is ".Net". when the "Active solution configuration" is set to, "Debug". When the, ""Active solution configuration" is set to "Release", then I can choose either, ".Net" or "Any CPU" under the "Platform" column. I am using Visual Studio 2005 Professional Edition. This website was previously built using Visual Studio .NET and was recently upgraded using the Visual Studio 2005 Professional Edition Upgrade Wizard. I need to target x86 specifically because the are components used in the project that are only x86 compatible.

  • [change] Vlookup onto another workbook

    - by Arcadian
    Hello, here is my dilemma. I have two worksheets one that has the name of clients and one that i want to copy the names to depending on the city. For instance: associated to each column is last name, first name and city. i have hundreds of names associated to different cities and what i would like is from worksheet1.xls to copy all the New York clients to worksheet2.xls either when i open worksheet2 or via macro what ever is easier and because last name is in one cell and the first name is in the other i would have to copy both. I saw that its possible to link cells from one worksheet to another and then do a vlookup depending on the criteria. Is that the best easiest way or is there another? thanks in advance and cheers oleg

  • File-level filesystem change notification in Mac OS X

    - by Paul J. Lucas
    I want my code to be notified when any file under (either directly or indirectly) a given directory is modified. By "modified", I mead I want my code to be notified whenever a file's contents are altered, it's renamed, or it's deleted; or if a new file is added. For my application, there can be thousands of files. I looked as FSEvents, but its Technology Overview says, in part: The important point to take away is that the granularity of notifications is at a directory level. It tells you only that something in the directory has changed, but does not tell you what changed. It also says: The file system events API is also not designed for finding out when a particular file changes. For such purposes, the kqueues mechanism is more appropriate. However, in order to use kqueue on a given file, one has to open the file to obtain a file descriptor. It's impractical to manage thousands of file descriptors (and would probably exceed the maximum allowable number of open file descriptors anyway). Curiously, under Windows, I can use the ReadDirectoryChangesW() function and it does precisely what I want. So how can one do what I want under Mac OS X? Or, asked another way: how would one go about writing the equivalent of ReadDirectoryChangesW() for Mac OS X in user-space (and do so very efficiently)?

  • How do I change a Git remote HEAD to point to something besides "master"

    - by jhs
    Short version: How do I set a Git remote's HEAD ref to point to something besides "master"? My project has a policy not to use a "master" branch (all branches are to have meaningful names). Furthermore, the canonical master repository is only accessible via ssh://, with no shell access (like GitHub or Unfuddle). My problem is that the remote repository still has a HEAD reference to refs/heads/master, but I need it to point to a different branch. This is causing two problems: When cloning the repo, there this, warning: remote HEAD refers to nonexistent ref, unable to checkout. That's confusing and inconvenient. The web-based code browser depends on HEAD as a basis for browsing the tree. I need HEAD to point to a valid branch, then.
