Silverlight Animation

Silverlight uses timeline concept for animation (not frame based, used by Flash). There is a StoryBoard at the heart of every animation here. StoryBoard can contain one or more Key Frame elements.

There are 4 type of Key Frames here:
1. Linear : Moves from the starting state to the end state in a smooth, linear fashion.
2. Discrete : Jumps from starting state to end state instantaneously.
3. Spline : Moves from the starting state to the end state varying speed based on mathematically defined curve.
4. Easing : A more evolved version of Spline, moves from the starting state to the end state based on a easing funcation.

Outlook Addin Setup Project

Prob:  Manifest registry key in Addins changing from
[PRODUCTDIR]MyAddin.vsto|vstolocal
to
[PRODUCTDIR]MyAddin.manifest

Sol: Install Visual Studio 2008 SP1

Report Viewer not working in dev server (the + sign for grouping is not coming, rather a red X image coming)

Prob. - The report locally works fine, but when moved to the web server and try to pull it up it throws javascript errors.

Error msg : 'RSClientController' is undefined .....
'ClientControllerReportViewer1' is null or is not an object.

What's odd is - it appears the report actually runs despite the javascript errors, but the resulting report has the red "X"s on the image tags in the control itself and the report returns no data.

Soln :

1. The .axd extension in the application config in IIS should set to use framework  2.0 instead of 1.1

2. If the 1st soln is not working,
Click on the application virtual directory in IIS7 and click on the 'Handler Mappings' section. Then 'Add Managed Handler'
Request path: Reserved.ReportViewerWebControl.axd
Type: Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
Name: Reserved.ReportViewerWebControl.axd

Once this was created, it worked fine in the Integraded mode AppPool.

3. Just add the following line to my web.config (it should get added automatically, but if not then ..)




 
4. If still not working !
- then, I have to see the code, post me that.

Soap Basic :

Interfaces for collections classes - System.Collection

Object-type collections classes are in - System.Collection
Generic collection classes are in - System.Collection.Generic
Specific Collection classes are in - System.Collection.Specialized

Generic interfaces:-
1. IEnumerable<T> - derives from IEnumerable interface
2. ICollection<T>
3. IList<T> - derives form ICollection interface
                  allows to access the collection with indexer
4. IDictionary<T> - implemented by ICollection interface
5. ILookup<T> - multiples values for a key
6. IComparer<&> - has only compare() function to compare two objects
7. IEqualityComparer<T>

Non-Generic versions of interfaces:-
1. IEnumerable - required if a foreach statement is used with the collection
2. ICollection
3. IList - derives form ICollection interface
             allows to access the collection with indexer
4. IDictionary - implemented by ICollection interface
                      has key and value pair
 

Ctrl+. and Shft+Alt+F10 shortcuts for Visual Studio

There are few great shortcuts for Visual Studio.

1. The Ctrl+. OR Shift+Alt+F10 - are great shortcuts for adding the required namespaces in a class.

2. Ctrl+E,D - This shortcut is for developers, who have the habit of keeping the code well formatted.

3. Shift+Alt+Enter - All time fav. - for full screen.
