Hi - I am trying to build a LOB application using Silverlight. But I am not sure what to use in the middle tier. I was thinking to use WCF Services only which I have been building for years but found MS asking us to use WCF RIA Services with Silverlight. I didn't find any reason why I should go for WCF RIA Services. Also there is not much documentation available on WCF RIA and as a developer I find lots of issues in getting guidance in building WCF RIA Services. Also I don;t find a suitable design to build WCF RIA Services layer. Any guidance on this is well appreciated. - SM

I have a class with a static constructor. First time I access the class the static constructor gets executed and there an exception occurs. After that if I try to access any of the methods of the class I am getting the same exception that was occured in the constructor. public class Test1 { static Test1() { //some exception here - ExceptionTest } public static void LoadData() { //if I access this method then I am getting ExceptionTest everytime I call this method. //The type initializer for 'X.Test1' threw an exception. } } How do I get rid of this? Thanks Shubho

ASP.NET Cache object or Using Static Variables. If static variables are faster then why should we use Cache object? Is it only for setting expiration? Is there any different between Application object and Static variables? Please advise.

Thanks a lot for your help. But when I checked it in ILDASM, I found that each control uses different standards. For e.g. for SelectedIndexChanged has a filed called EVENT_SELECTEDCHANGED. So the generic code that I am thinking of may not work properly. Pls advise.

Thanks Heath for your help. I got it what you explained but when I try that with this sample code, it didn't work. Please help me. Yoour help is appreciated. I have a TextBox "textBox1" in my windows form. I have a handler for TextChanged event. I am trying to remove this using this code. but it doesn't work. Please help. foreach(EventInfo ev in textBox1.GetType().GetEvents()) { FieldInfo fi = textBox1.GetType().GetField(ev.Name, BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance); if (fi != null) { Delegate d = (Delegate)fi.GetValue(textBox1); foreach(Delegate handler in d.GetInvocationList()) { ev.RemoveEventHandler(this, handler); } } }

That only gives the Delegate type, but how to actually get the reference to the Delegate?

Hi, To remove Event Handlers from my all controls in the form, I want to use a generic code as follows. 1) Run through all controls in the Form 2) Run through all Events of a control using Reflection .GetEvents() 3) For each Event, I want to get the Delegate, so that I can remove all using GetInvocationList(). but .NET doesn't provide any property to get delegate for the Event Handler. Please help. How can I get the Delegate for the Event Handler.

Actually the problem is that I don't know what all the EventHandlers each Derived Form is using. So it's become very difficult to remove all EventHandlers from each Derived Form manually. I just want to know if there is any way to remove all EventHandlers for all controls in the Form so that I can loop through all controls in the Form and Remove it in Base Form class. Please Help.

I am also calling .Dispose() after ShowDialog(). Still it is not helping...:(

Hi, I have a base Form and a base TextBox control. I have derived my Form and TextBox control from the base classes. In the base class of form, I am adding EventHandler for TextChanged Event of TextBox to do some generic operation like setting dirty flag. And again in the Derived View I am using TextChanged Event of TextBox Control to enable/disable the OK button. I am opening the form in Modal form. When I close the Form, it is not getting cleanup from memory. I checked it in .NET Profiler. In the profiler it is showing me that TextChanged EventHandler is still referring the Form. I want to cleanup all EventHandlers on Closed event of the Form. Pls let me know how I can cleanup all EventHandlers for all Controls in the Form. IT IS URGENT. Please let me know.
