C# - Start With Aspect Oriented Programming?
Mar 27, 2009
So having read some of the PostSharp documentation presented as an answer to my previous question regarding passive logging ([URL]), I am led to my next question: Where is a good place to start learning about Aspect Oriented Programming - I've done some searches on Google and I've read some articles - including the article regarding the topic on Wikipedia, but a lot of the material seems to assume you have a basic understanding of some of the terms which I seem to be missing, and that which doesn't just dives straight into integration leaving me not understanding what exactly it is I'm integrating.
Does anyone have any decent material targeted at someone who's never heard of Aspect Oriented Programming before today learn about the core concepts, terms/keywords etc? Even a birds-eye - i.e. These are the core concepts, keywords to look out for, what they stand for and how they fit together. After that, I can probably make some decent headway on my own. I'm most interested in AOP in relation to .NET development,

good tutorials where i can read about the actual object oriented concepts which we use in real time scenarios. Not the "class is a container. fruit is a parent class and apple is a child class" kind of stuff.Recently i was developing a multithreaded GUI application in vb.net and found out many obstacles like using one form's element in another form, changing form property in other class, when to create objects to access elements and many other stuff stumped me.

I'm trying to pick up some simple object-oriented programming skills so I am trying my hand at beginner's problem - and I am totally stuck...I'm trying to write a program that will print to a label, the area and perimeter of your shape of choice, dependent on the Length and Width (for Rectangles and Triangles) or Radius (For Circles) you input and the shape you select.
I know how to do this easily with simple event-driven programming, but I'm trying to do this by using classes and inheritance.The idea I have is that you enter in length/Radius and/or width into text boxes (txtLen, txtWid) and then you can click a button to display the Length, Width and Perimeter or Radius and Circumference, and Area.
I'd create a Super-Class: Shapes to define my overarching parameters - all shapes have area and perimeter. Then I would create sub-classes for each shape inheriting the overarching "Shapes" class - dim'ing all of their respective extra pieces. Then the buttons would display the appropriate info when clicked.I understand this seems like a lot - but really I just need help getting my feet on the ground for this.

i am new to asp and am currently trying to get my head around the visual basic language and Object Oriented Programming.From what i have read you need to have a good understanding of these to create good ASP.NET webpages, but from reading about these in books and joining the website [URL]..i am getting fairly confused with the language and the OOP. Does anyone out there have any tips for me when it comes to learning about these. Is there a good way to learn about these as i just seem to be getting really confused from the start.

I have been learning vb.net for about 6 months now and I red few books about basic visual programming as most to them have information about the basic concepts like what is Object oriented programming, subroutines, functions ,inheritance etc and bit about ADO connectivity to database. Having said all that I think I have good concepts about all these things but now I want to proceed further but can't find appropriate text books or online tutorials.

I am writing out an xml file that has the folowing root element:
<TileSet xmlns="D:\Programming\animationClassLibrary\animationClassLibrary"
xmlns:xsi="http:www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="D:\Programming\animationClassLibrary\animationClassLibrary tileSetContentsV3.xsd"
Height="100"
Width ="100">
Below is a snippet from my writing code:
Dim settings As New XmlWriterSettings()
settings.Indent = True
settings.IndentChars = ""
[code]....
Invalid name character in 'xmlns:xsi'. The ':' character, hexadecimal value 0x3A, cannot be included in a name.Without the schema identifying attributes, the writer works perfectly.

I'm using a web cam that takes 320 X 240 pictures. This sort of gives the picture a "landscape" look to them, and I need to re-size the pictures to a 169 X 225 "portrait" picture. Its for a badge program. Anyway, when I re-size the pictures, they get all scrunched up because of the difference in aspect ratio. Is there a way to re-size the image and the aspect ratio at the same time? Would this be considered cropping or resizing? I'm a little confused on where to begin. I mainly use VB, but if someone has a good example in C#, ill take the time to convert it.

I would like to ask some questions about the controls placed on forms :1) I noticed that VB .NET can create applications with XP visual style . If the "Application framework" is not activated , though , the controls look like those used in Win98 . This is useful to me sometimes . However , I wonder , is it possible to also see those controls in Win98 style during design time ? I am asking because during design time the controls on forms are represented with XP style no matter what style is selected .
This usually creates a problem to me because I can't properly set the dimensions for labels in order to fit their text . So , is there a way to also see those controls in Win98 style during design time ?2) Now this might be funny : I like both styles , so is there any way I could use both of them in the same project ?

How can I build a cropping tool such as the one in Office Picture Manager as seen below? Notice that as soon as the Aspect ratio is selected a cropped area shows on the picture that can be dragged to the perfect position creeping the aspect ratio in tact. This is why I wanted somehow to link my app. to Picture Manager. I want the picture to open in Picture Manager, cropping tool already selected, ready to be dragged to the perfect position. Unless you have some code that can do jut this.

I have the need to maintain a 4:3 aspect ratio on a Video control on a form. The forms (there could be up to 16 in a 4x4 layout) should all maintain a 4:3 aspect ratio when resized depending on clients monitor/resolution. The forms have a border and will keep them. The control is set to fill the form and is the only control on the form. Here is code that I use to create the initial layout:

I have a folder of images that I would like to loop through them all and resize each one to have a max of 100 in width or height, I have looked at the samples out there but none indicated where I can set the width and/or height and it will do it automatically, I would like to save the file in a new directory once I resize it.

I notice when I copy a control over a form (i.e. by copy - paste) , I don't only copy the visual aspect of the control but also the code is altered in relation with the new control . For example , lets say we have a Button on the form which is supplied with a sub for handling the Click event . If I copy the button then the existing sub will handle the new button too ! But I don't want that , I only want to copy the button (i.e. it has some specific color , dimensions , font etc and therefore it's faster to copy an existing one instead of creating a new one)

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

Our company currently uses an APL model to illustrate our life products. We are in the process of converting this to Excel/VBA because the APL system is extremely difficult to maintain.APL is difficult to maintain because the code has become over the years (~15yrs) spaghetti and only a select people (who have worked here 5+years) really understand this to make updates when new products come out. APL is also not well known and difficult to understand. I just would like help on designing the system, my main career is not a programmer, and the design I was envisioning was a "Procedural" approach. (the APL is procedural rather then object oriented. I have not used object oriented code before)Basically the program illustrates a life insurance product. That just means it projects a fund out from the time the policy is issued to age 120. The illustration is given to the policyholder as a way of predicting what the value of their fund will be given some assumptions.The program does the following1.) Populate Variables2.) Calculate Premiums Types3.) Monthly processing4.) Output values to spreadsheetThe system has to illustrate different types of Products and we are adding new products to the system. Most of the main structure of the program (in VBA) is already written. It seems that (#3) monthly processing will vary by product, and I would like help with maintaining that part of the code. The other 3 parts of the program are not a problem maintaining.We will be continually adding products. We will start with about 5 products and maybe add about 5 per year.Here is the Monthly Processing code:... Call MonthlyProcessing(120, PremPayMode0, Assump0, True, DumpLumpSum0)

how to do a seemingly simple object-oriented problem in VB.NET 2010. Basically, I want to be able to write code such that I could do the following:
Dim myObject as Object
myObject.Group1.Command1()
myObject.Group2.Command2()
[code]....
Very similar to how VBA handles objects, such as in Excel, I can use
Dim myBook as Workbook
Set myBook = ActiveWorkbook
myBook.Sheets(1).Range("A1").Value()
to get the value of the cell "A1" on the first sheet. This structure has been eluding me for some time now, and it would be great if anyone could suggest how to do it. I'm currently using a class and declaring all methods as Shared Friend inside subclasses, which throws warnings when I use it as I want to in other code.
