Public Event DataReceived(ByVal sender As Client, ByVal message() As Byte)
Public Event ErrorMsg(ByVal sender As Client, ByVal errormsg As String)

RaiseEvent Differ From Calling A Sub?

Dec 24, 2009

I'm working with RaiseEvent and have a question. Can an event in a class be raised from another class, or only from within the class itself? How does RaiseEvent differ from calling a Sub, other than the syntax of having an event and using "handles event1"?

VS 2005 RaiseEvent Not Working?

Apr 30, 2011

I'm having an issue with rasing an event. In my application I have a form and within that form I create an instance of a class (clsUsage). Within clsUsage I create an instance of clsUser which does several checks form permissions and other things. What I want is for clsUser to send status updates to clsUsage. ClsUser will be a dll but for now I've got it as a separate project in my solution. The RaiseEvent in clsUser seems to execute but the proc in clsUser that handles the event does not execute. I'm wondering if this is threading issue.

VS 2008 RaiseEvent In Multithreading?

Dec 23, 2009

I am using RaiseEvent in a thread and I pass a value to it and try to set a control's text to the value. Except I get a cross-thread error which is expected. I could invoke the control, but I don't want to have to do that.

My question is, is there a way to invoke/delegate the RaiseEvent itself so it will work on the ui thread without doing anything else?

Change Byte() To Structs For Readability And Convert Struct To Byte Stream For Socket Send()

Dec 8, 2009

I just converted the following code from c# to vb.net. It is functional and works correctly with my company's firmware/devices. My next challenge. Previous serialport code used much more readable structs which where then converted (after building a packet) into byte() automatically as part of the serialport encoding. (this is my understanding)How could I

1. morph byte arrays 'ToSocket' and 'ToMTP' below into structs and

2. convert into byte array for Socket.BeginSend(byte(),.....) to stream out to remote devices?

Truncating Data Types From Int To Byte, Transferring 8 LSBs To The Byte?

May 16, 2011

Is it possible in VB to truncate a larger data type ( an int with a value greater than 255) to a smaller one, say a Byte (which only goes up to 255) in a way such that the 8LSBs of the integer are copied to the newly created byte. I have tried this using CType with the following code, however it does not work.

Dim TestByte As Byte = CType(Test, Byte)
Where the variable "Test" is an integer with a value of 419. This code always results in the Overflow exception.

App Has Gone Beserk. Application.Exit And RaiseEvent?

Feb 5, 2009

I have an app which has been working fine for about 2 months. Yesterday, I carried out a maintenance session which was mainly simple bug fixing and moving my code into regions to help navigating through it. Along the way, 2 things have started happening which has totally broken my app.

MSDN states that Application.Exit does not cause the Form.Closed or Form.Closing events to fire.[URL]..However, my Form.Closing event is firing immediately after Application.Exit which is in a button click handler on the form. The code is like this:

.net - RaiseEvent When Debugging And Changing Execution Step?

Jun 20, 2012

I have this code in my application

If _oCurrentCall.CustomData.Length > 0 AndAlso UsageType = UsageTypeEnum.Vanlig Then
RaiseEvent NewIncomingCallWithCustomData(_oCurrentCall)
ElseIf UsageType = UsageTypeEnum.Sentralbord Then
RaiseEvent NewIncomingCall(_oCurrentCall, Queues)
End If

Without debugging the events are raised just fine and working.However, when debugging and trying to change execution step like dragging the execution step to the raiseevent in the other condition block, the event doesn't fire.

RaiseEvent Fails To Be Recognized By Handler Routine

Jul 29, 2009

I am having issues with a user created event being detected by the event handler. This program is in VB.net, defined in an OO way, and there are several other classes that implement the same interface and their class instances all detect the appropriate Event, except for one.

The following code is the base class:

Public Class CommandSpeedTest Implements testInterface
Private SpeedTest As New ArrayList()
Public Event testComplete(ByVal test As IEnumerable) Implements

[Code]...

This exact structure is being applied to three other classes (all of which are instanced using WithEvents in class gui) and being cuaght correctly.

Single stepping through code just executes the RaiseEvent line and goes to the next. It should jump to the event handler and execute the code there.

Convert Byte Array Into A String Like So Dim Byt As Byte()?

Jan 25, 2011

I have a byte array that I convert into a string like so Dim byt As Byte() = New Byte(255) {} s = New String(Encoding.ASCII.GetChars(byte))My question is when I look at the string in a debuger its clearly a normal string but when I compare it to what I know its supposed to be it doesnt equal. So i did a quick check and for some reason its return a string thats the length of 256 characters. So i did a s.trim and it still is 256 characters long.

Converting Unsigned Byte To Signed Byte?

May 6, 2007

I would like to know how to convert a unisgned byte to signed byte

Atm I got this

a
Function readSignedByte() As SByte
'-128/127
Dim b As SByte

[Code]....

it doesn't work one that well works for numbers positive over 127 if lets say ReadByte() has 128 it would give overflow error which I don't want it to give I would like it to overflow the number to negivate value aka its signed value.
