Getting C# DLL Events?
Mar 1, 2011
I'd like to be able to access the events in a C# DLL so I can display a Progress Bar as the file analysis is carried out - the DLL is written by a third party using VB.Net.
Details
C# FileAnaysis.DLL
Contains a public class FileManager which contains 2 public subs
public void ProgAnalysis(string fileName)
public void ProgAnalysis(string fileName, ProgressChangedEventHandler progressChangedEventHandler, RunWorkerCompletedEventHandler runWorkerCompletedEventHandler)
How do I access the events generated by second sub in Vb.Net?

I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

is there a difference between shared events and non-shared events?
Private Shared Event EVENT_something_changed()
Private Sub SUB_handles_something_changed() Handles Me.EVENT_something_changed
End Sub
no errors with this code, but how is Me possible since the Event is shared. it seems like there's no errors between switching shared with un-shared and switching Me with Myclass, all 4 combinations seem to work, isn't that weird

I find that I write a lot of code within my classes to keep properties in sync with each other. I've read about Events in Classes, but have not been able to wrap my head around how to make them work for what I'm looking for.For example, in this one I always want to keep myColor up to date with any change whatsoever in any or all of the Red, Green or Blue properties.
Class myColors
Private Property Red As Byte
Private Property Green As Byte
[code]....
If one or more of those changes, I want myColor to be updated. Easy enough as above, but is there a way to work with events that would automatically do this so I don't have to put myColor = Color.FromArgb(Red, Green, Blue) in every sub routine?

So, I'm at the stage where I have created checkboxes through the codes.Not through the toolbox.
They are added correctly to the form when I test it.Checkboxes can be checked or unchecked correctly.
But my problem is this:I want to use events mouseclick or mousehover with those checkboxes.

Is it possible to get an asp.net code (preferably vb.net) to query a sql server for results, but for it to somehow wait for a response from the server when a change is found in the records without resorting to server intensive loops?For example, I want to write a query which checks the date of a record, if the date is different from last known date, only then should the query return the results.

I am a VB programmer working my way into C#. I learned how to create and raise events in vb and am finding that it isnt done the same way in C#. Has anybody come across an article that will help me to understand how to do events in C# and maybe explain why it is different in VB.

In C#, I can do this:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)[code]....
Notice the line int i = c1.GetInt();. I can't seem to get VB.NET 4.0 to do something similiar.

I'm wondering if is it possible that the events for a certain object will be executed by another events under a different object?For example.I have a button named Button1, and I have a ListView named lstView. What I want is that when I click on Button1, the events that will be executed will be the one under lstView.
Here are my codes:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
lstView_KeyPress(Button1, e) 'This is the part where I don't know what to do.
End Sub

It looks like theres a bunch of threads with these issues. Mine has to do with events and event handing in an add-in...so its a bit complicated for me.I'm trying to rewrite this C# code
#region Event Handling
/// <summary>
/// Wires up events from xWeb and this plugin
/// </summary>
[code]....
I have no idea where the type AddinActiveDocumentChanged and the type DocumentEventHandler is coming from. Intellisense doesn't have these. So both of those sub routines I'm stopped at.

In VB.NET there is a keyword 'shadows'. Let's say I have a base class called 'Jedi' and a derived class called 'Yoda' which inherits from 'Jedi'. If I declare a method in 'Jedi' called 'ForcePush' and shadow that out in 'Yoda' then when calling the method on an instance of the 'Yoda' class, it will ignore the base class implementation and use the derived class' implementation. However if I have an instance of 'Yoda' that was declared originally as of type 'Jedi', i.e. Dim j as Jedi = new Yoda(), and called the 'ForcePush' method on the instance, it will use the Jedi implementation.
Now let's say I have an event that is called 'UsingForce' which is raised when the 'ForcePush' method is called, and I shadow the event out in the derived class (this is because 'Yoda' has an interface 'IForcePowers' that declares this event) and each class raises it's respective event.
If I have an instance of 'Yoda' that is declared as type 'Jedi' (like above) and I put an event handler on the 'UsingForce' event of 'Jedi', and then the 'ForcePush' method is called in the 'Yoda' class, will this event handler be reached?

I was creating some complex applications in Visual Basic .NET 2008 and since they are in the testing phase right now, people manage to find an error or two every so often that causes the program to crash. The problem is that there is a tracking piece to it that logs who is currently using the programs. When a user logs in, it logs that they are currently logged in, and if the form close event is fired, the log is deleted to show that they have closed it.
Now my problem comes whenever the form crashes from an error since it won't trigger the close event and therefore makes the log become inaccurate. My question is if it is possible to capture any error that the form would have in the form of an event?
