• How to print WPF FlowDocument within local report?

  - by Thorsten Dittmar

  Hi, in one of our applications we're using alocal RDLC-report (displaying using a ReportViewer control) to print some tables and text entered by the user. We'd like to give the user the ability of formatting the text. I thought I might use the respective WPF controls (embedded into the Windows Forms application) to make things easy. Question is: how do I print the resulting FlowDocument within the local report? Is this possible at all? Thanks for any advice, Thorsten

My thoughts were learning Scheme, making a working Zelda-like game(the original), find some open source project to help with.

• NOAA web service for current weather

  - by Brian

  I want to get the current weather conditions from the NOAA. I know they have a SOAP web service that can be used to get weather forecasts and XML files for current weather conditions for each of their weather stations. I could just use the XML file for the weather station nearest to where I want, but there doesn't seem to be an easy way to search for the proper xml file by zipcode. Is there a simple way to get current weather conditions by zipcode from the NOAA?

  - by Brennan

  I have found services like ClearSpring and Widgetbox for putting content snippets onto a widget range of social networking web sites, but I would like to build my own widgets without a third party dependency. I have been looking but I have not yet found a good resource to learn how to create widgets/gadgets for multiple sites. It was easy to build a gadget for iGoogle, but Facebook, MySpace and the others are less obvious. What is a good resource to create content snippets for multiple sites?

• REST/JSON: Should I include a newline after the JSON string?

  - by Mark Harrison

  If I'm returning ["foo"] from a RESTful web query, Which of these is more proper? Will pedantic REST parsing die on the newline? ["foo"]\n (with newline, Content-Length=8) ["foo"] (no newline, Content-Length=7) For easy regression testing I like the form with the newline, but I want to make sure I won't be breaking any application frameworks that might have a more strict view of the REST format.

• Using RhinoMocks, how do you mock or stub a concrete class without an empty constructor?

  - by Mark Rogers

  Mocking a concrete class with Rhino Mocks seems to work pretty easy when you have an empty constructor on a class: public class MyClass{ public MyClass() {} } But if I add a constructor that takes parameters and remove the one that doesn't take parameters: public class MyClass{ public MyClass(MyOtherClass instance) {} } I tend to get an exception: System.MissingMethodException : Can't find a constructor with matching arguments I've tried putting in nulls in my call to Mock or Stub, but it doesn't work. Can I create mocks or stubs of concrete classes with Rhino Mocks, or must I always supply (implicitly or explicitly) a parameter-less constructor?

There is hundred of solutions available but most are too complex for what we want or are not "stable" (not updated since a long time, not very well programmed). i was wondering if stack overflow's folks have some recommendations...

• Javascript disabling my postback

  - by LoveMeSomeCode

  I have an ASP.NET checkbox, and I want to run some javascript before it posts back. Something like: <asp:CheckBox ID="chkSelected" runat="server" AutoPostBack="True" OnCheckedChanged="chkSelected_CheckedChanged" /> but I want to run a JS confirm dialog when the user click it, and if they were UNCHECKING it, I'd like to ask them if they're sure, and if so, postback and run my serverside code. If they say No, don't postback at all. Anyone know of an 'easy' way to do this?
