What parameters do I pass to a Button Click Event. I just want to call a Button Click event from a TextBox. The only reason I'm doing this is so I don't have to repeat the code that is in the Button Click Event. I'm calling this Event from a KeyDown Event of a textbox.

View 2 RepliesHow would I go about passing parameters to a method? I would want to do the following:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ReceivingUdpClient = New System.Net.Sockets.UdpClient(6767)
Dim receiveBytes As [Byte]() = ReceivingUdpClient.Receive(RemoteIpEndPoint)
Dim ThreadReceive As New System.Threading.Thread(AddressOf receiveMessages(receiveBytes))
ThreadReceive.Start()
End Sub
Private Sub receiveMessages(ByVal receiveBytes As Byte())
'INSERT CODE

End Sub
Is there a Limit to the parameters that can be passed byVal or byRef to a function or procedure in vb .net ?

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
Code:
Imports System
Imports System.Windows.Forms
Public Class form1

I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]
View 10 RepliesI have 4 items in a ListBox and each item does a specific thing when it gets clicked on.But I also want the double click event to do the same thing as the click event.I can copy and paste all code from click event into double click event, but then you have lots of code crowding the code page doing the same thing. So what to do about this?

Private Sub listBox1_DoubleClick(ByVal sender As Object, ByVal e As EventArgs) _
Handles listBox1.DoubleClick

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.
I have a solution in Vb.NET 2008 windows Form with ToolStripMenuItems, but I need to implement menu navigation without any mouse intervention.I only found mouse events In ToolStripMenuItems, MenuStrip, etc.All MenuStrip and ToolStripMenuItems are created programatically, reading user permissions from Database, then add a handler to manage the events, but the client don't want mouse interaction, he wants only keyboard inputs only ![code]
View 2 RepliesI can't work out how to get the parameter types for an event.For instance, I can only see using a MethodInfo to get parameters, but I have either an EventInfo or a FieldInfo.What I want is to be able to get 'Boolean' from this:Public Event EventName(ByVal sender As Object, ByVal value As Boolean)I could theoretically try something like GetRaiseMethod() but that won't work (because that method returns null as per this link) and even if it did it would require a method binding first and this is meant to be for a test suite just confirming that the event has a certain typed parameter at initialisation.
View 1 RepliesI'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1? [code]
View 7 RepliesAs you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way

I have a listview set up in Details View and I run a ascending/descending sort routine on the appropriate column when the user clicks one of the column headers.However, when I switch companies and reload the listview with new information, for some reason the event fires and I get an indexoutofrange exception as I believe that the information has not yet loaded when this fires.The e.Column property is set to that of the previous column which I clicked even though I have clicked nothing.

First, Im new to VB but have been programming for 20 years.
Ive been creating an application that starts with a form that has 4 text boxes with corresponding search buttons.You key something in to one of the text boxes and click the corresponding search button and it would execute the code in the button click event. It worked.
Ive done something though to make it not work.When I run it and click on the button it doesnt run the click event.
If I double click on the button in the development mode, it should, I thought, go to the click event in the code but it doesnt.It creates a new click event with the same name as the original but with a_1 appended on to the end of the name.
