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

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

Something does not work: ORDER BY PaymentType = 'Visa';

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

Capture Canvas with Mouse pointer


I am currently creating an application which will capture Canvas control (i.e. Screenshot of canvas control) and save it as an image. For this I am using RenderTargetBitmap class. I am able to capture canvas control but I also want to capture mouse pointer. Is there any way I can capture canvas control with mouse pointer?

Code I am currently using is as below

 Dim r As New RenderTargetBitmap(cnv.ActualWidth, cnv.ActualHeight, 96, 96, PixelFormats.Default)
 Dim dv As New DrawingVisual
 Dim dc As DrawingContext = dv.RenderOpen

 dc.DrawRectangle(New VisualBrush(cnv), Nothing, New Rect(New Size(cnv.ActualWidth, cnv.ActualHeight)))

 Image1.Source = r

Changing Z-index order programmatically in C# with Control.SetChildIndex?

Hello developers.

I've recently build a Windows form app that contains 18 pictureboxes and 1 button.
I want the boxes on the bottom of the form to be on the front, so they overlap all the others.
And the boxes on the top of the form must be on the back, so they are behind all the others.

I can manually do this with 'move to front' and 'send to back' options, but I want to to this programmatically.
This is so, because I'm gonna add another picturebox that can move.
That picturebox should automaticly change it's z-index when it's Y changes.

At the moment the 17 pictureboxes have a random 'z order':
Some pictureboxes are on top, some are on the bottom, in a random way.
Now I want to set the z order correctly when I click on the button.

I've made code that sets the ChildIndex between 1 and 5 depending on the Y of the picturebox.
When the Y = 0, the ChildIndex will be 5, and when the Y = 400, the ChildIndex will be 0.
The pbBackground is also a picturebox, and this one's ChildIndex = 10.

My problem is, that my Windows form app isn't doing what it's supposed to be.

The picturebox names are pictureBox0, pictu

Hello World to C# Threading Part 1

In this post we will see how we can implement simple threading. Why do we need threading? When you want you application to do more then one thing at same time, then you need to implement threading. One usual and common scenario would be when your application needs to get data from some other resource like web services and you don't want you application GUI to be freeze during this time. In that sort of case you will run the code to access web services in separate thread so your application GUI won't freeze. The System.Threading namespace .NET provide interfaces to implement multi threading.

Threading in C#

What is Threading?
-Parallel execution of code pieces on CPU, commonly compiled codes started in a single thread but it is possible to create multi-threads within a program.


Multi-core processors are new standards on the user's hardware. By taking advantage of the multi-processing capabilities of these machines you can achieve significant performance upgrade with some minor changes in your code. When an application does not make use of threading techniques it is wasting valuable resources. This tutorial will cover the basic threading concepts and threading methods and properties.

Multi-threading in .NET: Introduction and suggestions

This article uses the C# type shorthands throughout - int for Int32 etc. I hope this makes it easier for C# developers to read, and won't impede any other developers too much. It also only talks about the C# ways of declaring variables to be volatile and locking monitors. Developers using other languages can find the equivalents in their own preferred environment, I'm sure.

GridView Sorting/Paging : 'REAL' AJAX with Asp.Net Series

This is a continuation of my 'REAL' AJAX with Asp.Net (not Asp.Net AJAX) series posts for those of us trying to stop relying on Asp.Net 'AJAX'.

Ok, nothing too dramatic to start things off, we are going to make some tabled data sortable and pagable all without using a bit of postback. Not only that, but it is going to be incredibly easy!
