Get Assembly Information For A Class That Is Part Of The Project But Not Executing
May 2, 2011Two of us at our company worked on a VB project. I developed the GUI interface. Another programmer developed some of the Classes that are also part of the project/Solution. Our manager wants to see as part of the 'Help/About' drop down, the version of the GUI application as well as the Class that the other programmer wrote. We are on the third modification of my GUI application, but the 8th version of the class that the other programmer wrote. Is there some way that the GUI application can get the 'Assembly Version' information for a class that may not necessarily exeuting at any given time?
View 3 RepliesPrevent The Class Library's Files From Being Opened During Main Project's Debug Mode?
Jan 24, 2009I made a Class Library project that contains the main classes that my Main Project needs because I don't want to main classes when I distribute my project. I've successfully called and used it in my Main Project. But when I started debugging and stepping through my code which involves calling and using the class I wrote in my Class Library, I noticed that the class' file in my Class Library opens up during debug mode.
how can I prevent the Class Library's files from being opened during my Main Project's debug mode?

VS 2008 Class & DLL's - Create Scripts On Their Own And Allow Them To Interact With Main Sub
Dec 12, 2011I want to start building my first large program. I want to create scripts on their own and allow them to interact with my main sub. I guess if I need a "plane" in my application, that could become it's own class? If I wanted to calculate "purchases", "money" I could create a DLL? I don't want to have to change things and have to recompile my entire application every time I want to change how something works for example.
View 5 RepliesCreate Event Log Source As Part Of Installation - Windows Forms App, Vs Deployment Project
Mar 27, 2011I have a vb.net windows form app that I am deploying as using the visual studio deployment project. The app needs to write event logs to the application log in the event viewer. For reasons explained here I need to create the event source during the installation process. Something like this to run as part of the installer
If Not EventLog.SourceExists(My.Application.Info.ProductName) Then
EventLog.CreateEventSource(My.Application.Info.ProductName, "Application")
End If
That code needs to be run during the installer with elevated privileges. So my questions are:
How do I execute that code above as part of the installer? How do I get the installer to do the UAC prompt to allow that code to run as part of the installation?

View 3 RepliesCreate A Project That Contains A Pet Class?
Jun 21, 2010Create a project that contains a Pet class. Each object will contain pet name, animal type, breed and color. The form should contain text boxes to enter the information for the pets. A button or menu item should display the pet information on a separate form. Hint: Use a ReadOnly property on the input form to pass the object to the second form.
What I have done so far is create a new class with the name Pet and have instantiated each object with readonly property. I have also created another form where the information entered by the user will be displayed. Guess I kinda need to know what would be the next step? And I want to ensure what I have done so far is correct.

View 2 RepliesCreate A New Instance Of Security Class For Every Form In Project?
Feb 19, 2009I'm creating what I believe is an mdi app.I have a login form.I have a class for security.My login form creates an instance of the security class. There are all kinds of security parameters for each user (permissions to different things, etc.)These parameters are part of my security class.Once the user logs in, many other forms will all be opened and closed within the main mdi frame.All of these other forms need the information of the security class to know what the user has permission to do.Do I have to create a new instance of security class for every form in my project? Isn't there a way to store this stuff globally somehow. Retrieve once from the db at the start of the app during login and just get it from this global area everytime?

Access To Object Passed ByRef In The Constructor Of A Class Through Another Part Of The Class?
Aug 18, 2009I have some classes, BsfciFile and StudyFlashCard. Bsfci is the extension to which I save my set of flashcards in an INI format. I am currently working to transform my code from using Windows API calls to access the INI to using a IniFile class that I found on the internet. I would like the BsfciFile to have a Array of StudyFlashCard objects, but I would like the StudyFlashCard class to use the IniFile class object contained in the BsfciFile class. I can pass the IniFile from the BsfciFile class to the constructor for the StudyFlashCard class, but I want it to modify the same IniFile as the BsfciFile class has later on.

View 1 RepliesInside The Service Class, Declare A Class Variable Named Started?
May 8, 2012Create a class named Service. Inside the Service class, declare a class variable named Started. The datatype of this variable is Boolean.Public Class Service Dim started as Boolean End Class Create a class named Server. Inside the Server class, declare a dynamic array that can contain elements of the type Service.(Note: For convenience, both the array and the variable Started can be accessible from a client program that creates an instance of Server and Service respectively)
Create a constructor for the Service class. When the constructor is executed, it will set the value of the class variable Started to True. Create two new classes: WebServer and DatabaseEngine. Both of these classes inherit from the class Service. Inside the Service class, declare a Sub procedure (method) named Terminate. This method should display the following text Service stopping in a message box when executed.This method can be overridden in classes that inherit from Service class.
Inside both the WebServer and DatabaseEngine class, override the method Terminate inherited from their base class Service. Both methods should first call the base class Terminate method. The messages Web server stopping and Database engine stopping should also be displayed in a message box when the Terminate method for the WebServer and DatabaseEngine are called respectively. These messages should only be displayed if the Started variable inherited from their base class is not equal to False.
Inside the Server class, declare a method named Shutdown. This method does not return any value. When executed, it will call the Terminate method for each of the Service instances (if any) in the arrServices
array. You should call the Terminate method within a For Each loop that loops through the elements of the arrServices array.
In the Sub Main method, create an instance of the class Server. Set the size of the arrServices array in
your Server instance to contain 2 elements. Create first a WebServer instance and then a DatabaseEngine
instance into this array. Call the Shutdown method from your Server instance.

View 1 RepliesHandle An Event Raised In Class Inside Own Class?
Apr 14, 2009I have a "partial" class in VB.NET. Half of it is auto generated by a code generation tool. That half implements INotifyPropertyChanged, so any properties in that part of the partial class raise the PropertyChanged event.In my "custom" part of the class, I declare another property that depends on one of the properties in the auto-generated side. Therefore, when that auto-generated property changes, I also want to raise a PropertyChanged event on my custom property that depends on it.
If I go into the generated part of the class and raise the event there, that will get overwritten if I ever re-generate that part, so I don't want to do that. I would rather add an event handler in my side of the partial class that checks if the generated property changed, and if so, raise another event for my custom property.
[Code]...
I'm assuming it's because normally you'd use the WithEvents keyword to tell the compiler that you're subscribing to events from that object. I don't have a clue how to do this inside of the class that's actually raising the event, or if that's even possible.

Unable To Publish Main Project
Aug 31, 2009Since I'm unable to publish my main project, I've decided to start from scratch to see if I can locate the problem. I created a brand new project, just a simple form and dragged 4 controls onto it (a label, a button, a combo box and a checkbox). There is no code in any of the controls.I published this using Clickonce at url...(I'm aware people may not be happy clicking links). It's set to run only from the webpage. It runs fine on this PC, but on my friends PC and on my spare PC, it simply churns up a page of html error codes.
