C# - ICustomAttributeProvider.GetCustomAttributes(...): Design Strangety?
Jun 23, 2010
The MSDN Documentation: MemberInfo.GetCustomAttibutes Method (Type, Boolean) states in the remarks:This method ignores the inherit parameter for properties and events. To search the inheritance chain for attributes on properties and events, use the appropriate overloads of the Attribute.GetCustomAttributes method.This basically means that this implementation's second parameter (bool inherit) is ignored for event members and property members. However, calling the ttribute.GetCustomAttributes(MemberInfo,Type,bool) variety of this operation does not. Why would they seemingly ignore the inherit attribute arbitrarily on 2 forms of member types?

I am struggling to get the syntax for the reflection call GetCustomAttributes ... at least I don't seem to be able to get hold of the custom attribute which I've decorated a particular method with. The complicating factor maybe that I have passed that method into an extension method as a generic delegate. (The other, more likely, complicating factor is that I'm not sufficiently familiar with reflection or what happens when you pass a method as a parameter like this!)
The code appears to run, and when I step it, the count returned from the GetCustomAttributes is 1. I can't work out how to get hold of that custom parameter

I am struggling to retrieve custom attributes from a method. As you can see, the method ProcessXML has a custom attribute. The method itself gets passed into an anonymous delegate and then, in that context, I'm looking to get its custom attributes, but I'm not sure quite how to do it.
Here's my code
Public Sub UpdateXML()
Dim errors = New Errors
Dim xml = <testxml>

I seem to have reached a limit on the size of the form. I cannot make the form longer and I need to add more fields. Is there a limit on how many fields can be included in a form?

I have found so many such as tustena but unfortunately they are not domain driven based and in these solutions I could not find a good modelling documents or references. i am a newbie in CRM but I am sensetive to design it with solid object-oriented fundamentals. Any reference or open source solution especifically for CRM design and implementaion in .NET? Cheers

A little but pissed off at the moment as I have just lost a few hours of work. While I was trying to get a form to resize better (so you can make the form bigger and have all the panels and therefore things inside the panels take up the same percentage of the form), I thought about looking in the designer code to see if anything in there would be easy to change to make it work the way I wanted.
Upon finding what I thought was going to be a good bit of code to edit (code that placed the panel in position), I changed it so that panel2 would find where panel1 was (in the y axis), add panel1's height onto panel1's Y location and use that value as panel 2's Y location:
Me.Panel5.Location = New System.Drawing.Point(0, Panel1.location.Y + Panel1.height)
When I switched back to the visual designer view it came up with a warning page (blue bar across the top of the page saying "To prevent possible data loss before loading the designer, the following errors must be resolved:".Therefore I went back into the designer code and deleted what I had previously done and was a little bit annoyed that I couldn't use that code which I hoped I could.Upon going back to the visual design page everything was gone so I went back to the design code but everything was still there.I sighed in relief and ran the program and everything loaded properly so I decided to quit and reload the project to revert to before the incident occurred to be able to see the design in design view.When I reloaded the project everything was still gone and I then found out that the code from the design had gone too meaning I had lost it all. The code that I created would work in the vb coding, I have tried it.

I am working on a windows forms project that will allow a user to have an interface to the database, and another will be a nightly run process file that will update the database table.The user will add new records to the table, whereas the nightly process will update the columns with new values (think mortgage interest rates)
Both these projects will be using the same business logic component that has the calculations needed to enter values into the table.The way I am figuring this out, is that I will have two exe's (one for the interface and one for the nightly process) and have a central object that will host the calculations. What would be the best object for this purpose?A class file?A windows service? (I want to stay away from a windows service, because it will have to be running all the time)

I wonder if somebody could point me in the right direction. I've recently started playing with LinqToSQL and love the strongly typed data objects etc.I'm just struggling to understand the impact on database performance etc. For example, say I was developing a simple user profile page. The page shows basic information about the user, some information on their recent activity, and a list of unread notifications.
If I was developing a stored procedure for this page, I could create a single SP which returns multiple datatables covering all of the required information - resulting in a single db call.
However, using LinqToSQL, this could results in many calls - one for user info, atleast one for activity, atleast one for notifications, if I then want further info on notifications this may result in further calls - multiple db calls.
Should I be worried about the number of db calls happenning as a result of using this design pattern? Ie, are the multiple db handshakes etc going to degrade my db etc?

To write a effecient Active Directory library to ease the work of technicals who are responsible to create access models into the domain controller's Active Directory. This library must allow the following:Basic operations: Add, Modify, Delete, List entries;An entry may either be an organizational unit, group or user (no further need required as of now);I thought about having a class which would represent the domain with which we want to work with.
public class Domain {
public Domain(string root) {
Root = root;

I was loading my project when my computer rebooted suddenly. After it came back up, I went to load my project again and got an error about "an error occured when loading in the design view..this has been disabled" - sorry I did not get the exact message but it was something like this. Then when my project opened up, I now cannot see my form in the design view anymore. It still run's fine, but there is no code displayed and the form itself does not display in IDE anymore. I can see the code for the form only on the form.designer.vb mode.I have continues backup installed, and restored several versions of the class files for the form, but yet still no luck.
