With WPF(Windows Presentation Foundation), we saw the complete designer-developer separation,making it one of the best presentation technologies available at present.
    Windows Workflow Foundation(WF) brings about the separation of the ‘when-and-what’,says Bruce Bukovics,author of Pro WF: Windows Workflow in .NET 4 (Expert’s Voice in .NET).You get to change the when without touching the what.All the business logic are packed into components,activities rather(in WF terms) and the control flow is between the activities is ‘declaratively’ controlled.Don’t be surprised,its XAML again.

    Though being newbie on WF,I got to take a session on WF,at my workplace, which made me dive little more deeper into it(so that I don’t bluff my way through the 1 hour session :) ).All I could explore was the overview of the features,which seems promising and interesting.
    This book I got hold of seems to clear the way ahead and make it easy.

    More on WF soon :)

    nokia n95 review Of all the mobiles I have used till date this one goes top on my rating.With its elegant design,built quality and power packed features,the N95 8GB was worth every penny spent.8GB was not much of an attraction though, but definitely it being internal memory,boosted the performance.No longer I felt the time lag in apps opening,as in the previous models of Nokia.
    Though its been a long time this big monster has been released it demands this piece of space here.
    Not going into the specs of the phone,for there are sites which gives them in and out like this one here.
    The 5 mega pixel camera is definitely a lookout feature,for you no more need a dedicated camera,if all you want is a snap of the moment.
    The two way slide feature with dedicated music keys makes it to be on the race with pmp’s out in the store,with the battery lasting pretty enough for an average music lover.
    With the wide range of apps available for the symbian os , this definitely was the king of its times…..Nokia N95 8GB

    **edit: **here goes a list of must have apps in the n95

    With all banks stopping on EMI(Equated Monthly Installment),with recession at its high,I was left with no choice for a long time,but to depend on internet cafe’s,as my compaq V2624TU got some hardware problems and wouldn’t start up.Blogging was on the verge of stopping…..thanks to my brother,Sagar,who turned my new banker for the brand new HP DV4.

    Thanks a lot bro :)

    Got to start saving though,for always bankers might not be there nor will EMI’s(they really helped for my previous purchases).
    Hoping to make it a resolution(you always want something’s to be broken),for the year 2010.

    Happy New Year :)

    Quite a few of you might be thinking on what this “Stars” are :).It’s nothing other than the “ little medals under ones Display Name “.Think I have put you again in thought.Not for too long but,it is the MSDN forum rating that I am talking about.
    I started answering posts as a pastime.Soon I noticed this little stars ,varying in count, under different display names.A little bit of exploration gave me this piece of information.
    The ‘Pastime’ turned an ‘Addiction’.

    “Do they pay you??”
    “Are you rewarded??”
    “They might give you something!!””

    The common statements that I heard, whenever people see me browse the forum.
    None of these were the reason for my addiction though.It was just the personal satisfaction I get from answering the questions, a new learning and a different perspective for some of the problems I had already faced.

    “It’s not money that always counts….. …..Stars too count”

    Hi,
    Of late I have developed the habit of reading books,most of them technical and few others which i feel interesting or of controversial topics.Now in the era of computers you get all the books of choice available right at the click of a button.But I prefer the Hard copies rather than the soft one.
    Usually I go through the e-version of the book to get a feel about it,before buying.
    Whether to read the ebook or the hard copy is purely of personal interest.I prefer the latter just coz of the feeling of having a book in hand and reading is great rather than sitting in front of a monitor/pda.Moreover I spent a lot of time in front of the monitor,coz my work demands it ,so i just don’t want to add a reason to spend more.

    The question is not “which is better”,it’s just about getting into the habit of reading :)

    Happy Reading :)

    Hi, Many a times while using listbox,listview etc there might be a need to delete the multiple selected items. This can be easily achieved by the following piece of code

     While ControlName.SelectedItems.Count > 0 
       ControlName.Items.Remove(ControlName.SelectedItem)
    End While

    Happy Coding :)

    After a long time after my first microsoft certification,70-536,.NET Framework - Application Development Foundation today i have taken the certification for WPF, Microsoft .NET Framework 3.5, Windows Presentation Foundation Application Development,70-502.
    This one is easy for anyone who has some hands on experience in WPF.One has to be familiar with the different panels and layout,Binding,Styles and Templates.Other than that some knowledge on click once deployment would also be of help.
    The best way to prepare for this,would be to have a visual studio up and running and try out different things on WPF.
    I would suggest the books Sams WPF Unleashed and Pro WPF to start with.Both are really helpful.Apart from that check out the various blogs and forums out there.Just google and you would find a hell lot of those,just like you found this one:)
    Just gonna relax the day ahead after the hard earned certification :):)

    Hi, Everybody will be using Brushes,which implements a set of predefined SolidColrBrush objects,to choose various colors. Sometimes you may want to get a list of all these brushes up in your application,so that the user can select the color of his/her choice. To get the list of colors from Brushes you can use the following piece of code

    Dim dictBrushes As New Dictionary(Of String, SolidColorBrush)
    For Each objPropertyInfo As PropertyInfo In GetType(Brushes).GetProperties
    	If (objPropertyInfo.PropertyType Is GetType(SolidColorBrush)) Then
     		dictBrushes.Add(objPropertyInfo.Name,objPropertyInfo.GetValue(Nothing, Nothing)) 
    	End If 
    Next

    Here dictBrushes will give what you want. You can use this in your view,bind to a combobox if you want and show the possible selections of color

    Hope it helps :)

    Recently I had a requirement when developing an application,where i needed a listbox which was to be disabled but yet can be scrolled,so that all the contents in it was visible.Applying the property,IsEnabled=False makes the whole listbox disabled even disabling the scroll. I just found out a way around this.I created a custom listbox(MyScrollableListbox) with a property IsItemsEnabled.Setting this property to true,gives the normal listbox behaviour.When set to false only the ItemsPresenter of the listbox is disabled,so that scrolling is possible

    The Custom Listbox looks like this(just one property added for now)

    Public Class MyScrollableListbox
        Inherits ListBox
    Public Property IsItemsEnabled() As Boolean
     Get
     Return GetValue(IsItemsEnabledProperty)
     End Get
    
    Set(ByVal value As Boolean)
     SetValue(IsItemsEnabledProperty, value)
     End Set
     End Property
    
    Public Shared ReadOnly IsItemsEnabledProperty As DependencyProperty = _
     DependencyProperty.Register("IsItemsEnabled", _
     GetType(Boolean), GetType(MyScrollableListbox), _
     New FrameworkPropertyMetadata(Nothing))
    
    End Class

    In the xaml(or if you are going to make it a custom control then you can give it in your Generic.xaml)

    Now if you set the property IsItemsEnabled to false the listbox will be disabled,but allowing you to scroll.

    Recently I had started using FxCop,which is a wonderful code analysis tool.Soon after getting into it,I felt the need of rules specific to my requirements and standards.One such need was in the area of ‘Naming of Variables’.
    Every project/organization might have their own naming standards and rules for variables. FxCop provides a way to make sure everyone in the team adheres to these rules.
    I found this material quite interesting and helpful.
    FxCop And Code Analysis

    FxCop analyzes the CIL( Common Intermediate Language) ,so it is supposedly to be language independent.The CIL genarated by the vb compiler and the c# compiler are almost same,but there are diferences which needs to be handled and taken care of while writing custom rules.
    One such example i faced in checking for naming convention of string variables is posted here.

    You can always see the CIL genarated using the ‘ildasm’ tool which comes with visual studio.
    It would be helpful ,if you look at the IL genarated while writing rules,as writing rules is always a trial and error method.
    One other tool which comes handy is Reflector.

    Will soon post more on writing custom rules.Hope this helps to start with!!!!
