Make An Object Of A Detailed Checke?
Feb 7, 2011
I have not asked any questions in a long time because I have not been programming. But I am now back again with a question about Graphics.I want to make an object of a detailed checker. What I mean by detailed is there is going to be a big ellipse, then it is going to have a hole bunch of ellipses going around the edge to give it the checker affect.
How do I bind it all or make it all into one object and do something like a button has when clicked (Handles Button.Click) but with this object so I can move it.Is it possible to do this? If so can someone tell me how?
PS. This is my first time dealing with Graphics, so go easy on me ;)

making a very simple detailed listview visually, not programatically. I have now added a listview to the form and added the columns I need. But how do I add rows to the list? When I add items to the list it seems to just add some sort of category or something. So can anybody tell me how to make a simple detailed list or show me a tutorial on how to do it?

Here's an example of a wasted day:
(1) I want to find out exactly what Binding.FormattingEnabled does.
(2) I type MSDN Binding.FormattingEnabled into google and go to the page.
(3) I read the 3, 'helpful', line description.
(4) I check out the bottom of the page for references.
(5) Never mind, non of those helped....
(6) I search google and find nobody seems to know what the property does in its entirety.
(7) I open up reflector and spend hours in a tangled web before being 70% sure I know what's going on.
(8) I carry on coding, but the 30% is niggling at me.
(9) Repeat 6 - 8 ad nauseum ...
There must be a better way!
I'm using VS.Net 2008 Express edition, btw.
ETA: The FormattingEnabled property was just an example, this is more of a general question. Using reflector, I'm about 94.314% sure of how it works..

Good, detailed resources or books for best-practices on exception handling? I am looking to dive into a much deeper understanding of it, and am finding it hard. All the books I see over .NET, ASP.NET, etc. place little emphasis or detail on exception handling.
I am currently testing out a 3-tier ASP.NET application, with a presentation layer, business logic layer, and data layer, and want to know more about exactly when to throw errors, when to catch them, what layer to do them in, etc.
I don't want a simple google search on ".NET exception handling" and then having you post the first couple of links. I would like you to respond if you have quality, known resources that you have used or have found.

connect to 2 separate databases that control a system of logging in/out and the other a database of items. Think of it like logging in to ebay and searching for items. The only problem is that the x64 computers that will be used to run the final solution dont allow for MS Access databases or SQL databases to work for whatever reason.What other options do we have in order to have an effective system? A series of generated text files with the input registration details is so far the

I have written a program that queries an sql database displays it in a detailed listview, no problems so far. The only problem I am running in to is when I got to print the listview. When I do a regular printdocument.print() It prints out the listview exactly how I have it set up to do so. Which is a title , then column headers, next comes the listview, and then a total of some the columns. When I do a printpreview everything looks great. When I click the print button within the printpreviewdialog only the Title, Column headers, and the totals print. [code]

I tried out the tutorial on [URL].. that shows how to do a simple report with the Microsoft Report Viewer control. I really like this control.I wish to further my skills on this nice tool but can't find any step by step tutorials on creating many different types of reports even if I do a Google search. I'm hoping to find tutorials on reports such as group break reports, sub-total reports, charts in the reports, drill down reports etc.
Does anyone know where I can find these? If they don't exist yet, would you create them so the community will benefit?

Each business object has a matching object that contains sql calls. I'd like to restrict these sql objects in a way where they can only be used by the matching business object. How can this be achieved?
Update Greg brought up the point about testability. Since the SqlObjects will contain very business-process specific sql I don't want them reused in multiple buiness objects. (Basic CRUD operations are all code-generated) Is there a way to make the SqlObjects accessible to only one business object in the business assembly (like yshuditelu and Greg Beech showed) AND expose the SqlObjects to the unit testing assembly?

I am having issues finding resources detailing building Speech Recognition grammars using VB.NET, Speech.Recognition.GrammarBuilder, and .NET 4.0. I have found a few examples on the Internet, but they seem to just go over the basics. Does anybody know where I can find a good source on detailed information, as well as Speech development in general. I mostly see links to class definitions, but no explanations and discussions.

The other form contains 2 text boxes (Name,Phone) and Date time picker, and I have remove and save. The remove button should change the backcolor of the label that was double clicked in the first form to white. The save button should change the backcolor of the label that was clicked in the first form to yellow. Yes I am using an array.

I have an EggSac object which contains references to >100 000 Egg objects. Some variables in the Eggs have to be maintained to be consistent with EggSac, so I want to make these only changeable by EggSac. However EggSac passes references to its Eggs all over the application, so if I use public methods then any other code could modify the secure parts of the Eggs by accident.
What's a proper OO way to make sure only the EggSac object can call the "secure" methods of the Eggs, but still make the "safe" methods available to everyone?
My idea is to split Egg's class into a base class containing only safe methods and a derived class containing the secure methods that only EggSac should have access to. Then EggSac has members of the type of the derived class, but it casts them to their base class whenever something else wants one.

In this chunk of a code, the writer makes a reference to a recordset object and I just wanted to make sure I understood why before moving on. [code]...
In LoadDataBound, it says set rs = GetData(). This calls to the Function below, but why does it require to be set as an object of the rs recordset. Correct me here, because i'm most likely wrong, but does it require this so that you're able to make a function out of the recordset without having to use the same name for both (recordset and function) ? Or is there another process going on here that i'm unaware of.

Is there a way I make a file that contains the information for a contextmenu?The reason I'm asking this is because I want to make a program that can customize a contextmenu and then turn it into a file that can be opened by another program I'll make so it can be used by the new program.I feel I'm not explaining well, so I'll try to break it down. This will be slightly hypothetical, and this is the case that I find out how to do this.
I open my program to create the context menu that will do tasks specified by the tag for the buttons. So I create all the buttons in my app, then I press a button and it saves the contextmenu as some sort of file, this file can then be opened by my other program. My other program opens my contextmenu file and applies the contextmenu to a textbox. So how can I do this?

I put some group boxes on a user interface and now labels and pictures that are set to visible can't be seen even when the group box is set to visible = false. (I have the group box and the pictures and labels in the same place on the form and was planning on using buttons to make them visible and invisible but the pictures and labels stay invisible no matter what while being in the same place as the group box.)
Does anyone know why group boxes do a sound job of making things invisible and how to correct it?
