Get Track Of All New Instances Of Classes
Jul 26, 2011
when i create a class ( ie ahuman ), i declare a object (ahuman) , i give it properties and with the properties i also can set the property ahuman , by creating the property ahuman (new) and set its variables, and declare its variables by declaring properties like weight, lenght, female or not.the problem for me is that i have multiple forms multiple class files , i cant oversee how to get track of all the new instances of classes.it is much easier to use pulbic shared properties to use a method in another class.

I am trying to make a pretty complicated, layered program.I have my main form which creates an instance of another form (addValue and myAddValue). From myAddValue I then want to access a few other classes to do various verification and other bits of code.Here though I have a problem.With the form ContactDetails, it just can't seem to read myAddValue.txtName or the others.If I try and read AddValue normally it says about it not being able to access a non-shared member (Expected that this doesn't work, it was just an attempt at something different)How do I read myAddValue from a class which isn't the one that created and isn't the one that it is an instance of?

2. FunctionLayer -deals with Common Operations which get results from DataLayer and return results to Forms.3. User - deals with User. (For Reusing the User Class in other projects, i have separated this class)Here in Class2 - I have an instance of Class1( ie., DataLayer) for DB Operations.imilarly in Class3- I have an instance of Class1( ie., DataLayer) for DB Operations.Now in my form, If i create Instance of Class2. But When I need user functionality in this form, I have to create an instance of Class3 to this form.

with one form and 1 class it is simple.but i have now 4 forms and 4 classfiles with 8 classes.i only need 1 commandlist with 20 commands i made them classes form 4 makes a private instance of the commandlist with the dim statement so i cant use it througout the projekt if i chance it in public , i get the reaction of visual studio i must replace it with dim (private) i read it is better to make instances ( dynamically)then to publicly share your classes(static)but i want my instances to be used by all forms and classes.

I have two classes, one nested in the other. [code]Neither "Name" or "ID" are unique between operations and records.I wish to construct a dictionary using LINQ = Dictionary(Of String, Of List(Of Integer), whereby the keys are uniqe examples of Names in my collection and the values are the collective set of distinct IDs that are associated with those names.

How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.

I simply want to extract the string "bar," which is inside <hostName></hostName>I can do this easily enough with simple string functions, but I'd like to do it with one of the .NET XML classes/methods.

Before anyone tries to close this thread thinking this is for malicous purposes, let me tell you that it's not. What i'm working on is an application to save screenshots to files as soon as the 'Print Screen' key is pressed, as Jpegs or what ever. What i want to do is be able to minimize the application and I still want the application pick up on any 'Print Screen' presses, and save the screenshots. I've tried using the KeyPress event, but I soon realized that it only worked when the application had focus. I plan on using it to save screenshots every time I press 'Print Screen'

So basicly ive made a media player in vb using the windows media player control and everything is fine except that when i use the trackbar to navigate on a video it starts stopping and starting like a scratched cd (there is nothing wrong with the video file) strangely this does not happen whilst playing audio files the shaking stops if i pause it for a second ant then play it again but incorporating a pause in the trackbar function does not help. This the code i found on the internet but this produces the same result:[code]...

The problem I'm having is that I can't find a way for my .NET application to get the song that is currently playing like MSN can. I've been searching alot all over google but all I get is "how to play music in vb.net" and that is not what I'm looking for.

I've done a trackbar like photoshop by using a panel and a picture box and move it in mousemove event, anyway this track bar was very slow because while the user is scrolling the trackbar it gives an event to change the hue of a picturebox,the track bars should be like the hue, saturation, lightness track bars in photoshop.

I have two combo boxes, and four buttons. When the user clicks "Add" on the first combo box, it adds a new item to the combo box with "New" and then lets the user rename that item to something else. That "new" item has to have an array of "answers" that go along with that item in the list. What I'm having trouble figuring out is assigning "answers" to the second combobox for each item in the first combobox and changing the second combobox when selecting an item in the first combobox.
EXAMPLE:
Item 1 - Combobox1
- Item 1 - Combobox2
- Item 2 - Combobox2
