.net - Record And Replay Raised Events?

Mar 13, 2012

I implemented the communication between two classes by using events in VB.Net.Now I want to store (record) all events that occure and to re-raise (replay) them again later.

Here is what I have already:

Class1:
Public Event Button1Pressed(ByVal sender As Object)
Private Sub btnButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnButton.Click
RaiseEvent Button1Pressed(Me)
End Sub

[Code]...

I could add another handler to the event I want to record, but then in the handler I only get the parameters that are passed to the event and not the event itself.Another thing I don't know how to solve is, that I can't raise an event from an extern class.

.net - Events Raised By BackgroundWorker Not Executed On Expected Thread

Mar 22, 2010

A winforms dialog is using BackgroundWorker to perform some asynchronous operations with significant success. On occasion, the async process being run by the background worker will need to raise events to the winforms app for user response (a message that asks the user if they wish to cancel), the response of which captured in an CancelEventArgs type of the event.

Being an implementation of threading, I would have expected the RaiseEvent of the worker to fire, and then the worker would continue, hence requiring me to pause the worker until the response is received. Instead however, the worker is held to wait for the code executed by the raise event to complete.

It seems like method I am calling via the event call is actually on the worker thread used by the background worker, and I am surprised, since I expected to see it on the Main Thread which is where the mainform is running. Also surprisingly, there are no cross thread exceptions thrown.

.net - Should Events Be Raised In New Threads To Not Block Current Work?

Dec 15, 2009

I'm currently designing an assembly that will be used by third parties. One of the classes has a long process of TCP connections and it informs about its process using events. For example

''# Do stuff that takes some time
RaiseEvent CompletedFirstPartEvent()
''# Do stuff that takes some time

[Code].....

What I've seen if that if the handler of one of those events takes too long (or even worse, it blocks) I can have timeouts and it's hard for the developer to see that one class is not working fine because his handler is taking too long.

I was going to fire the events in a new Thread to avoid this issue but this looks strange to me because I've never seen something like that, what I've seen until now is the developer spawning a new Thread if his handler was going to be timeconsuming. So the question is:

What would you do? Create a new thread or force the user to create his own thread? (Or is -there a better approach that I don't know?)

Record And Playback All Keyboard And Mouse Events

Oct 8, 2010

I am writing a program to record and playback all the keyboard and mouse events using the journalrecord and journalplayback methods. The code also stores this recorded event in the file and opens the file for playing. The mouse movements are playing fine but none of the mouse clicks or keyboard keypresses are playing fine. Attaching the record and playback hook procedure.

Replay A VB Audio File Or Stream?

Sep 21, 2010

I am trying to write a little synthesizer program, and as a first step I am creating .wav files opened for reading and writing using the code below called from a button click event handler. The audo plays but once, no matter how many instances of the Audio.Play method are called. I also tried closing the file and then calling the Audio.Play method on the full path name. In each case, the audio plays but once. If I click the button again, the file will be played once more. The duration for the audio is one second, so I am sure that it is only being played once every time. I do not want to loop the data. The idea is that when the user plays a new note, I update the file and replay it with the new data. Since the file is recreated every time I click the button, I guess what I *need* is working, but I am still curious why I cannot replay the content of the file.

' Create a file stream object for reading and writing.
Dim FS As New IO.FileStream(fileNamePath, _
IO.FileMode.Create, _

ASP.Net Event Only Being Raised Every Other Time?

Mar 9, 2010

I have an ASP.Net web user control which represents a single entry in a list. To allow users to reorder the items, each item has buttons to move the item up or down the list. Clicking on one of these raises an event to the parent page, which then shuffles the items in the placeholder control.Code fragments from the list entry:

Public Event UpClicked As System.EventHandler
Protected Sub btnUp_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Handles btnUp.Click

[code]....

It originally looked in testing like every other time the value for sender (verified by its properties) that reaches UpClicked is of an adjacent ListItem, not the one I've just clicked on - the first click is always wrong, then the second for the correct control.At present,testing appears to show that the button's click event is just being ignored every other time through.Breakpoints on the click events within the control simply aren't being hit, though the events are definitely being established.

.net - FileSystemWatcher Changed Event Not Being Raised?

Apr 29, 2009

I'm working on a Windows Service that watches a few folders for changes, creations, and deletions. It all works well with the exception of one watcher that watches a single file (XML File with Configuration Settings) for minor changes.

I tried taking the Windows Service code and putting it into a simple windows application with start/stop buttons for the filesystem watchers and stepped through it. It never detects the file change of the XML config file. The changes are indeed occurring and the "Date Modified" of the file is updating.

XmlEventReferences = New System.IO.FileSystemWatcher()
XmlEventReferences.Path = "C:XmlReferences"
XmlEventReferences.Filter = "*.xml"

AccessViolation Exception Raised While Calling A VC++ Dll?

Jul 15, 2011

We are trying to call a VC++ unmanaged Dll from VB.net 4.0 application. During execution the application breaks and gives AccessViolationException(Unable to read or write protected memory). When we press F8, F10 or F5 it continues execution and give us correct results. And it is anonymous i.e. sometimes it works cleanly sometime it breaks. We tried everything ( debugging the Unmanged code, different ways to create unmanaged dll etc..).

Vc++ method signature: unsigned long LZCompressBuffer(unsigned char *SrcString, unsigned long SrcLen, unsigned char *DestString, unsigned long DestLen)

VB.net calling: Public Declare Function LZCompressBuffer Lib "CompExpand.dll" (ByVal buf() As Byte, ByVal slen As UInteger, ByVal dstr() As Byte, ByVal dlen As UInteger) As UInteger Mostly it generates error in memcpy() (String.h) method

Handle An Event Raised From A MODULE?

I must be missing something really basic, but I just can't figure this out. I have a module (declared as a Module, i.e. a VB "static class") and I have an event declared in it, and places to raise the event. But I can't figure out how to handle the event.

Let's call the module MyModule with an even MyEvent. Like so:

Event Raised In Constructor Cannot Be Handled Outside Very Class

Oct 26, 2009

I discovered that an event raised (directly on indirectly) in the constructor cannot be handled outside the very class. To prove if that was the actual problem, I wrote a simple exemplary app.
Class with the event:
Namespace Utils
Public Class A
Public Event Test()
Public Sub New()
CallTest()
[Code] .....
The reason of such behavior became quite obvious after writing those pieces, but maybe there is a way to omit it?

Get Index Of Item In Collection That Raised Event?

Jun 30, 2010

In a list of timers, how do I determine the index of the item that elapsed without having to iterate the collection as shown below (e.g. can I pass a paramater to OnTimedEvent, or can the collection raise an event to say which item fired???). It's the individual timer index that I need as I'm using it to refer to something else.

(I wont know how many items I'll have in the list in advance so I can't create an individual event handler for each timer - I don't think I should even if I did).

Public Class Form1
Private _timers As New List(Of System.Timers.Timer)
Private Sub Form3_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

VS 2005 Update UI In Event Raised From Thread?

Jul 3, 2011

I want to raise an event from a non-UI thread where the event will be handled by the UI. Currently, I have to use .Invoke in my methods (which updates UI) called from the event.

How can I raise the event, similar to Background Worker's progress update event, where I don't have to specifically do an .Invoke for UI updates?

Do I wrap the event with a delegate or something? Sample code will be fine though, if the explanation was tedious.

VS 2010 SelectedIndexChanged Raised On Each Mouse Click?

Nov 22, 2011

If you set a listbox selectedindex in code the SelectedIndexChanged event is only raised if the item isn't already selected, So why is the event rasied when you click a selected item with the mouse?

Here's what I came up with to get around the problem (which seems unnecessary and silly), So if there is a built-in or better way I'd sure like to know.
