What order the GC collect generations?

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :WPF

I have a question about the order of generation to collect. It looks not an important question, but it will be helpful to my clear understanding about the GC.

My Question is:
What order the GC collect generations?
Does it collect from Gen0 to Gen2 or from Gen2 to Gen0?

If the GC collects generations from Gen2 to Gen0, I think it must know the triggered collection is
ephemeral generations or not. If it does, when and how it can know which generation it should collect?
(Of course, assume that it is not triggered by LOH, which always needs a full collection.)

I think it is natural and easy to implement that the GC just collects Gen 0 and decide to collect an older generation or not.

ASP.NET: Collect Customer Order Information on an Internet Site Using XML and Web Forms


XML has quickly become the new data structure standard for everything from database access to cross-platform computing. XML is typically considered to be a vehicle for data exchange, dynamic data presentation, and data storage. However, the potential of XML far surpasses those limited applications. This article examines one new use: the gathering of data across a number of forms in an ASP.NET Beta 1 framework application. The sample program is a Web app used for ordering pizza. It uses ASP and C# to gather order information and then stores it in XML. To build the application, several concepts are explained, including data collection, order persistence using cookies, grouping input forms, and formatting the data for display.

In Table I shrajeno Mastercard, Visa, Diners etc ...

All Visa are the first in the order, another Mastercard, etc. ...

Collect Feedback workflow hidden field


Hello all,

I am using the out of box Collect Feedback workflow.  It works well for most part.  However I would like to get reviewer's feedback to be shown on a Dashboard.  Is there a way to expose that information in a Data View?  I couldn't figure out which data field stores the feedback information.


Modify User in Collect Data from User Workflow


I've created a workflow with a Collect Data from User action that emails a Group when the task is created. Once the task is claimed by an individual, the Assigned To column in the task list is updated to display that person's name but once the task is completed the email variable for the action is not updated and the group is emailed instead of the person listed as Assigned To.

So the question is this: Is there a way to update the user varialbe in the workflow task once the task is completed, or would I need to build my own workflow and use the Send Email action?

SSIS Changing Column Order during Transformation

First let me say, I really can't believe this chain of events myself--and they are happening to me. I am upgrading several DTS packages to SSIS on what will be my new production server.  These packages create tables, export them to a flat file, and ftp them off to other locations. What is happening (on the SSIS side) is that the OLE DB Source is reordering some of the columns on its own (moving them to the end of the table/file.  Then when my pickup/load routines run, the data is out of place and they fail. Can anyone please explain what is happening here with the mapping.  I have evaluated the table and the columns are in the order that I expect.  When I preview the source table in the OLE DB Source Editor the columns are in the correct order/alignment, but when them in the OLE DB Source Editor --Columns section within BIDS the order is changed arbitrarily. I have been somewhat successful (2 out of 3) in being able to re-map the data, but this last table just doesn't want to change.  Thanks in advance for any help and/or information you can provide
