  • Tool for making quick UI drafts

    - by Moshe
    I'm looking for a tool that can be used for sketching UI (specifically web UI). The sketches/drafts can look as simple as if it was drawn by hand on a whiteboard. Preferably, this tool should be free/open-source and run on Linux as well as on Windows, but this is not a must. Could you recommend?

  • C#, cannot understand this error?

    - by 5YrsLaterDBA
    I am using VS2008. I have a project, SystemSoftware project, connect with a database and we are using L2E. I have a RuntimeInfo class which contains some shared information there. It looks like this: public class RuntimeInfo { public const int PWD_ExpireDays = 30; private static RuntimeInfo thisObj = new RuntimeInfo(); public static string AndeDBConnStr = ConfigurationManager.ConnectionStrings["AndeDBEntities"].ConnectionString; private RuntimeInfo() { } /// <summary> /// /// </summary> /// <returns>Return this singleton object</returns> public static RuntimeInfo getRuntimeInfo() { return thisObj; } } Now I added a helper project, AndeDataViewer, to the solution which creates a simple UI to display data from the database for testing/verification purpose. I don't want to create another set of Entity Data Model in the helper project. I just added all related files as a link in the new helper project. In the AndeDataViewer project, I get the connection string from above RuntimeInfo class which is a class from my SystemSoftware project as a linked file. The code in AndeDataViewer is like this: public class DbAccess : IDisposable { private String connStr = String.Empty; public DbAccess() { connStr = RuntimeInfo.AndeDBConnStr; } } My SystemSoftware works fine that means the RuntimeInfo class has no problem there. But when I run my AndeDataViewer, the statement inside above constructor, connStr = RuntimeInfo.AndeDBConnStr; , throws an exception. The exception is copied here: System.TypeInitializationException was unhandled Message="The type initializer for 'MyCompany.SystemSoftware.SystemInfo.RuntimeInfo' threw an exception." Source="AndeDataViewer" TypeName="MyCompany.SystemSoftware.SystemInfo.RuntimeInfo" StackTrace: at AndeDataViewer.DbAccess..ctor() in C:\workspace\SystemSoftware\Other\AndeDataViewer\AndeDataViewer\DbAccess.cs:line 17 at AndeDataViewer.Window1.rbRawData_Checked(Object sender, RoutedEventArgs e) in C:\workspace\SystemSoftware\Other\AndeDataViewer\AndeDataViewer\Window1.xaml.cs:line 69 at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs) .... InnerException: System.NullReferenceException Message="Object reference not set to an instance of an object." Source="AndeDataViewer" StackTrace: at MyCompany.SystemSoftware.SystemInfo.RuntimeInfo..cctor() in C:\workspace\SystemSoftware\SystemSoftware\src\systeminfo\RuntimeInfo.cs:line 24 InnerException: I cannot understand this because it looks fine to me but why there is an exception? we cannot access static variable when a class is a linked class? A linked class should be the same as the local class I think. "Linked" here means when I add file I use "Add As Link".

  • Location of Firefox throbber/spinner image

    - by Premasagar
    I'm trying to locate the "throbber" (or "spinner") image used in the Firefox 3.6x chrome to show that a request is being processed: I'm not familiar with the source code structure for Firefox, and a simple search hasn't yielded the answer. Does anyone know which file I'm looking for? (E.g. can you provide a link to the file in the Mercurial repository, or tell me how to find it?).

  • Windows Phone 7 Tab Pages (page cycle)

    - by cw
    I know.. I know, it's only a few hours old. But how the hell do you get the little page tabbing/cycle (forgot what the official name is) on the top of the page under the app title. MIX Keynotes made it look like it was a control (or at least what I saw, was @ work). Anyone who made MIX or knows how they are doing this, it'd be cool to get an answer. Thanks!
