Make Object Backcolor?
Nov 17, 2011
I am coding an application for seats reservation and it contains two forms one of the forms contain 32 labels that represent the seat number and when the user wants to reserve that seat, he/she can double click that label to bring up the other form . 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.

Simple question...is it possible to check the backcolor of an object, like a label for instance? What I want to do is check if a label's backcolor is green (or some other color) then have something else happen based off the color. Here is what I tryed, but neither worked...

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 making a simple maze game that you use the arrows keys to navigate. I completed the movement part of it, but now i'm having trouble with the walls. How can you make an object not pass through another and how to tell the program what to do when a object gets to a defined place(the finish)

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.

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 ;)

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?

I am struggling to do what i want with classes at the moment as they are killed off at the end of a method, can somebody let me know how to make the classes live until i tell them to die? so that i can create one and refer to it from another method at another time? For example On form load i create a class Dog.Then later on i want to get info from the Class Dog. But it is no longer instantiated

I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.
How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.

I only started using visual basic earlier this year so I'm still a newbie but I've been wondering some things:
1. When you have a picturebox back color to transparent, objects under it still get hidden. Is there a way around this?
2. I've been trying to make a program where you can control an object, and it has multiple animations, but I can't figure out a way of doing this other than having a bunch of picture boxes together and making them visible/not visible as needed. Is there a better way to do this?
3. (I think) I know how to make global variables (dim whatever as global.system.integer ? I don't have it on the computer I'm posting with), but how do I make another form use them?
4. Is there a way to have multiple sounds play at the same time? Whenever I play a sound it stops whatever else is playing.
