RaiseEvent Tick But Only Once?
May 20, 2010
I have a situation where I want to run the code in the Tick event ONLY ONCE not on the interval i have the timer set too.So I figured I would just do thisRaiseEvent MasterTimer.TickBut that gies an error saying mastertimer is not part of the class.Why won't that work?How do I call the Tick event manually without Start() Stop() the timer?

I have the following code:
Protected Overloads Overrides Sub OnInit(ByVal e As EventArgs)
MyBase.OnInit(e)
Dim login As Login = TryCast(Control, Login)
[Code]....
I get errors on line 7, 8 and 9 stating that I should use RaiseEvent to obviously raise an event. I am stuck with this after searching google but I can find no real explanation of this in terms of the login control

I have client/server app.I have a class for the tcpclient and a class for the tcplistenerIn my tcpclient class I have a system.timers.timerThe timer elapsed event fires a public event(in the tcpclient class) which the tcplistener class handles.During debugging I see the timer firing its elapsed event and calling raiseevent on the public method, yet the event is never fired in my tcplistener class.

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"?

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.

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?

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:

As the subject says, I was wondering what's the difference between the InvokeMember("click") and RaiseEvent("click"). Also I see around example of InvokeMember("onclick"). What's the difference with just "click"?

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.

The problem seems to be that the codes below are events and cannot be called directly. I want to know how I can properly use the RaiseEvent statement while still keeping these where they belong, smack in the middle of the rest of my huge code:

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.

I have a class in VB.NET that has a method (called CurrentValue) that returns a number. There is also an event that the class raises to indicate the number has changed. In the event handler on my form, I update a textbox using the exposed method.[code]When I run this I get a "Debugger.Runtime.CrossThreadMessagingException" error. What could be doing this? I am instantiating MyClass in the same form that contains the textbox.I can also set properties of the MyClass object without any trouble.

I'm new with VB and a time program I'm trying to complete is incorporating a tick event. I have the code I need to use, and have the timer placed within the VB Designer but when I start the debugging process, 12:00:00 pops up in the text box. I would like to have it start incrementing after I set the hour, minute and second and initiate the Set Time click event. The code I have for the timer is

I have three checkboxes on my datagridview namely, Yes, No, Inv. If the value is set to True in the table which populates the datagridview the respective checkbox is checked and if false unchecked.Now, when on runtime I try to check a checkbox on the Yes Column I receive the followinf error;
DataGridView Default Error Dialog
The following exception occurred in the DataGridView:
System.FormatException: is not valid value for Boolean. -->System.Formatexception: String was not recognised as a valid Boolean.
at System.Boolean.Prase(String value)
at system.componentModel.BooleanConverter.ConvertFrom(ITpeDescriptorContext context. CultureInfo culture, Object value).........
The No and Inv allow me to check and uncheck the checkboxes as many as I want without generating the error.

I used a timer in my user control now when Timer_Tick event is fired I want to raise an event like Ticked. I created:
public delegate sub myDel()
public event myevnt as myDel
in Timer.Tick
I used raiseEvent myevnt. I also raised the event from a button click. This event is handled in a windows form where the control is used, My problem is event is firing when the button is clicked but not firing from the timer.tick. Is there any problem from Timer.Tick.

I'm in the process of designing a game, how can i make the game tick over in time?
First thought would be a timer but is this the correct way?
Also I'm looking at building this game in WPF, By memory WPF does not have the timer control, what would you do then?
