Even better, break that monolithic Console.WriteLine into 4 seperate WriteLine statements.

You seem to be confusing overload with override. Since you did not have virtual methods and overriding, the compile-time type of the variable was used which returned "Shape" instead of the name from the derived class. You should check your book (this kind of codes suggests you are either working examples out of a book or taking a class) or the internet for the syntax.
P.S. - I'm all for using breakpoints as C.G. suggested to see the where the code is going, I just thought you could use a nudge in the right direction on this one.

ok, here is what i am looking to do;
I have a project where i am making a Html Editor using VB.NET Win Forms. I am looking to allow the user to select page header graphics, overlay other images, gradients, glare images, ect ... and when they export the web page the program to take those pieces and export them out as a single image.
I have not done much at in the way of GDI/GDI+ programming.
Does any one have any ideas has how i can do this? or a link or two to a few articles that explain this?
Thanks for any help.

Easy enough. Create a Bitmap object the size of the resulting image that you need, then create a Graphics object from that Bitmap and call its DrawImage method to draw those images onto the new Bitmap where you need them.

I need to be able to read an XML file into a database table that has been exported from another system where the schema may be different to my database table.
Is there a way to dynamically parse a schema to map fields and add them to a database table?

There's no autoamtic way to do it. You'd have to write the code that takes the data from each column and puts it into the correct column in the dataset/datatable.

Hi,
I am new to VB (using VB 2008 Express) and am trying to write a program to access my ADSL router and download the traffic statistics. The normal way to access the router is to open IE or Firefox and enter a URL. This calls the router which initiates a new "Authentication" window prompting for a username and password.
I have successfully created s simple form and can manipulate the buttons and textboxes. I can also output some text to a file. I am completely stumped though when it comes to the webbrowser box. If I implement a webbrowser1.navigate("192.168.1.1) command the router initiates an IE "authentication" window. My program stops until an entry is made into this external window. I am also not experienced enough to know if this could also be triggered from HTML or java code. Is it possible to gain control of this window from inside the webbrowser commands ?
I would greatly appreciatte some clues as to how to solve this issue. I am not asking for code as I really want to solve this myself rather than just copy and paste. That teaches nothing.
Thanks in anticipation
Regards
John

Hi,
We have a Windows Service, written in VB.NET. This service is set to start Automatically on machine start. Authentication/log on parameters are included while setting the Service.
However, we now notice that the service does not start on reboot, returning a Service Failed to log on error. Starting the service manually works without problem.
Server: Win 2003, .NET 2.0
Any help towards a solution would be most appreciated.
Regards,
RB

Write any errors that may occur during startup of the service to the eventlog. Maybe a network connection isn't ready or something similar.

Have you tried setting the service to retry it's startup if it fails? You can set it to retry after so many minutes after the 1st and 2nd failed attempts.

You may have some other services or resources on the system that are not ready when the Windows service is started, for example SQL server usually will usually not be ready when your Windows service started.
You should trap the exception to debug what is causing the failure, ie using AppDomain.CurrentDomain.UnhandledException or Application.ThreadException (can't remember which one for services, don't have the code with me now).

Hello to All,
When i am leaving my application for some minutes.Then again access it then my softwares textboxs color is showing black.
Do u know what is the reason behind it?
Thanks
If you can think then I Can.

The color of a textbox is always black. Do you mean that the background is black ? It's something weird on your machine, no code does that automatically, and if you've not written code to style textboxes, they are not going to style themselves.

Hello to All,

By buying a PDF library, finding a free one that works, or by writing your own converter.

Please send me basic idea for writing pdf document.

I'm speechless. Please re-read my post. You need to buy a library, or find a library, or write a library. The end. There's no 'basic idea' I could put into a forum reply, except perhaps to type 'buy PDF library VB.NET' into google. Atalasoft has one.

Christian already answered this. You need to either buy some converter software, or find a free version on the web. Search google and you will find many possibilities. If you wish to do it yourself through programming then you need to get a copy of the latest PDF specifications from the Adobe website. Either way it requires some small effort on your part.

And it's clear how that's likely to turn out....
