I have a central page loading child controls into a container in a Silverlight Project.Problem is events like button click events are fired twice after processing the child forms.Suspect it might have something to do with a double initializecomponent??

View 2 RepliesI have a silverlight page with a textblock and button on it. Like this:
<TextBlock x:Name="txbNote" Margin="50,50" Text="Hello"/>
<Button x:Name="btnCheck" Height="40" Click="btnCheck_Click" ClickMode="Press" Margin="50,50,50,50" Content="Check Service"/>
Here is the handler for the click event:
Private Sub btnCheck_Click(ByVal sender As Object, ByVal e As EventArgs) 'Handles btnCheck.Click
txbNote.Text = "I Was Clicked"
End Sub
[Code]...
The only change is the relative position of the textblock and button. The button's click event (and every other event I tried) just doesn't fire unless the textblock is before the button in the xaml.
my source code in design part is:
<asp:Panel ID="Panel1" runat="server" Style="display: none" CssClass="modalPopup">
<asp:Panel ID="Panel3" runat="server" Style="cursor: move;background-color:#DDDDDD;border:solid 1px Gray;color:Black">[code]......
Ok button click is not accessing click event.
I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.

View 2 RepliesI have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.
View 2 RepliesI want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.
Can i Know how to catch between these 2 event, Leave and Click?
I have one checking in a textbox Leave event. I will go check whether this ID is already exist in DB or not. If exist, I will prompt MSG box to user.
When I click on Close button while focus is on textbox, this textbox Leave Event will trigger first before Button Click event.
So, the form remains open without trigger Button Click event.
how to prevent this textbox leave event or how can i catch/control this situation?
i declared a global variable button:
Dim button1 As New Button()
Now, i dont know how to add a click event in this button since it is a variable.
How can you chnge the location of a ovalshape using button and 2 textboxes in a button click event
View 1 RepliesI believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

View 1 RepliesI 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.
[code]But even here it seems the handler isn't registered until after New has completed.However, in real life the event is raised within code that's semantically part of the object initialisation, and I'd really rather not have to create some Initialize function.
View 2 RepliesIf 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.

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"

I want to write an event that will simply display something when it is raised. I have never really worked with event driven programming before and am just trying to get a simple example working. It is not yielding any errors, but when I switch to debug mode I can see that the event it not raising correctly.

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:
Module MyModule
Public Event CallHelp()
Sub ExamineStuff( ByVal input As String)
[code]....
The event handlers in my parent class are never called though the events are raised in the child class.
The Code:
Public Class childForm
Public Event checkboxchangedEvent(ByVal checkbox1 As Boolean, ByVal checkbox2 As Boolean)
Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

I have an MDI application that can either run in TABBED or WINDOWED mode. When a user selects something from the menu a form is shown. All menuItem clicks pretty much look the same:
Dim frm As New <SomeForm>
frm.MdiParent = MDIParentForm
frm.Show()
[code].....
I have a test class with an implementation similar to this:
public class MyObject Public Event testEvent(ByVal duh As Boolean)
Public Sub New()
'some code here
End Sub
[Code]...
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?
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

I'm new to VB and relatively fresh in programming in general. I'm trying to write code to make a label flash red. The method involves using a timer. Problem is, it flashes, but I can't figure out how to make it stop. xD Here's my
