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 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?
im using webbrowser control and html code in my project my question is how to see other invokemember events like ("Click") is there any complete list of events,

View 1 RepliesI am using the HtmlElement's InvokeMember function and was wondering if there is a nicely formatted list of all the strings that can be passed into that function.So far I know about these strings that can be passed into InvokeMember:Click, Focus provide a link to a list of all strings that can be passed into the InvokeMember function or write them down?

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.
View 1 RepliesI 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'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"?
View 2 RepliesI'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've tried various methods... such as;
WebBrowser1.Document.GetElementById("id").InvokeMember("submit")
WebBrowser1.Document.Forms(0).GetElementsByTagName("INPUT").Item("id").InvokeMember("click")
but none of them have worked... (I aso changed the form name to its correct name instead of 0, but still no luck). Here is the html button I'm trying to click.

I would like to invoke a click on a link from a link that is generated by an HTML query. I am attempting to program an application that queries a website and am getting hung up where I download the .csv that is loaded by the website.[url]...
cansim9170974256855749928 from the url is not static and I don't know how to work around this. I thought that this link would be helpful and should be except there is no link ID to reference. Is there a way to enable a clicking event on a random csv link? I have mashed together some failing attempts at this off and on for some time now and am now in your hands.
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:

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.
