Is it possible to create a list that would contain both the Checking balance and the Savings balance since they are separate classes?
I have a couple of list boxes and would like to scroll them all at once so each item is kept in sync against the rest of the lists.

Not Sure if this is the right forum to ask this question, but could not find any specific forum for CAS.
I am using CAS in one my VB.Net based application. I am using Imperative Security. I need to use the SecurityPermission class and need to allow access to Execution and Unmanaged Code Security Flags.
I am not able to find a way to add multiple flags in the constructor of the SecurityPermission Class. how to set up multiple SecurityFlags for the SecurityPermission Class in VB.net? C# will be fine.

ok, I'm basically trying to make mulitple drop down lists on my form. When the page loads, I can get my main dropdown list, called makelist, to fill in with the items that I want from a txt file.
What I'm trying to do is whenever the selectedindex is changed in makelist, it has to load a different dropdown list, called modellist with items from a different txt file.

I have 2 lists of classes with thousands of elements. Each class has the same structure.
I need to synchronize the 2 lists by comparing the version, the dateandtime and if they have been labelled to be deleted in one list.
is there any trick to make this very long process as fast as possible apart from splitting the work on threads?

Im having a hard time trying to pass the values from a list inside of a class. Im trying to display multiple lines of values from a list inside of a class. My "client" class stores multiple lines of values into a list(of class transaction), with the number value(num) counting each transaction that it adds to the list.
Code:
Public Class Client
Private m_tranlist As New List(Of transaction)[code]....
im trying to display each line that is stored in the list in a label, and im having major trouble. I know all of the results are added into the lists, but how do i call the list in my main form in order to display each line of all of the values? Would I have to look up an index or something?
If I have a generic.list(of ClassA), is there a simple way to create a deep copy of this list that will not affect the original copy? It seems to work if I have a generic list of Structures, but for some reason the copy constructor for lists of classes only copies pointers to the elements (or maybe a pointer to the whole list?). I would move to structures if it were not for the fact that I can't find a way to edit the members in the structs in the list. eg:list(0).a = 5 'Does not workIs there some way to get around this without declaring an instance of that structure, like this:dim str as StructA = list(0)str.a = 5I'd

View 1 RepliesI have several different lists I want to call. They all have the same format for the class:
id, value, description, order.
Instead of creating a bunch a classes to return the all of the many lists, I wanted to use generics and just tell it what kind of list to return. However, I can not figure out how to populate the classes.
Here are 2 examples of function in my calling code. This should indicate the type of list and the stored proc used to get the data:
Public Function getTheEyeColors()
Dim glEyeColors As New GenericList
Return glEyeColors.GetALList(Of EyeColor)("GetAllEyeColors")

Sometime ago I used to create all my class structures in vision before I wrote them. That however didn't last. I found it easier to just make little drawings with pencil and piece of paper. And I still do to this day. In code usually those drawings manifest themselves as interfaces which then are implemented by different classes. I do all this in code. And I was just wondering if there is any tools available in Visual Studio for VB.NET that would allow to create interfaces and implement them in classes (which a lot of times means just adding variables to class that will hold data passed with interface attributes) from design mode(kinda like using Visio only after you finish you don't have to write out code).
View 3 RepliesCreate a class to deal with records from the Classes table, much like the Student class we created in Lecture #17 handles Students records. The name of the class should be Ualb_Class (note we cannot use Class, as it is a reserved word in VBA). All of the fields should have corresponding properties. There are few considerations:
The class (course) code, department code, and course number are set at Initialize, so there is only a Get property method for those
The property for Meeting Day only accepts one of the values defined in the table. You can decide whether to accept an integer value or a string value of the days represented.
You are also to code the Initialize method, much like we coded the Initialize method for the Student class in Lecture #17. In the Initialize method, you will use the InputBox function to obtain the department code and course number. use a different InputBox for each value, so you don't have to mess with separating the single text value returned from that function. The Course Code will be obtained by using a function that has already been created, called GetNewCourseID. It has no parameters.

I am creating an Add-In that I want to create classes and forms based on a database structure. I can't find any information anywhere on how to programatically add code to classes. I know I can write out the files and add them to a project, but that would limit what I can do in the future. I would like the possibility to update a function in the future which would be impossible writing out a file and loading the whole thing back in. It would destroy any modifications made to the class, and since this Add-In will only be creating a framework, there will usually be modifications.
I got this line from the macro recorder:DTE.ActiveDocument.Selection.text = strDACode
But I like to keep Option Strict on, and this is late bound according to the IDE. There seems to be very little help on the IDE and how to use it creating Add-Ins. If I overlooked something please point me there, but I can find nothing. I don't know if it can be done, but I was able to do it in an Add-In for VB6.I would also like to add controls to a form, so if anyone can point me somewhere where it explains
I have an interface that i have declared some of the basic internal functions, subs, properties, etc. This interface is then implemented into 3 pre-defined classes. These classes are end-use classes so they dont get derived or inherited elsewhere. I am trying to create a generic shared class that can operate on each of these 3 predefined classes and potentially more as long as they implement the interface.

I am very new to this whole programming thing and I have read several books and many websites but I can't get a good start on creating a video poker game. I understand that I need to create classes, but have no idea how to start. Most of the things I have been reading have been for Visual Basic 6.0 and it appears hard to understand. I am looking for some type of tutorial of how to create the classes I need and how to get the actual information from the classes into my form. Can anyone out there provide me with a good starting point? Is there any good (and easy) code out there to get me started. I feel that if I can get a good starting base, I can learn from there.

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:

I realize the problem is the $AE$7 (the $A$3 is correct)

Is there any short cut method instead of iterating over for earch?
This is probably a really basic question - but I have a list of items (custom objects) being passed from one winform (.net 3.5) to another. I want to create a local list to store changes that only get persisted if the user clicks save. Currently if the user clicks cancel - the changes are still applied in the first form because I assume the objects are reference type.I have the save working as it calls a service layer to do the save and then refreshes the other form - but not the cancel.
View 1 RepliesI am cleaning up some code and I have multiple classes that are 99% exactly the same. So my understanding is that my options are...
1. Create a class and all other classes inherit from it and modify it a bit
2. Create an abstract class and all classes inherit from it and modify a bit ** I took this route
3. Create an interface and all classes Implement that interface.
Here is my 'original' class below (the one that all of them look 99% identical). This class is used in an arraylist so I have a listing of all my images from a folder I have searched.
