ListView Click Event Not Firing?
Mar 3, 2010Using VS 2005 I've created a project with some form on it. Each of the forms are fairly similar in structure and I have copied the contents of one form to another form etc. I have code the loads the data into the ListView on each form and that works fine but when I put a Click event on the ListView, it doesn't fire. I created a new project to do some testing and put some items in the ListView and the Click Event fires when I expect it. What am I overlooking? The code for the Form is included below: it loads the data fine and I can select a line in the ListView but as previously stated, the Click event just won't fire!

Event Firing Twice?
May 25, 2010I am using a monthcalendar inside of a panel. when the user changes the "showweeknumbers" of the calendar I need to move some label to the right of the calendar, but I also need to resize the panel. The problem comes into play when the user hides the weeknumbers, the monthcalendar resize event fires and the labels move, but the panel resize causes the month calendar to fire the resize event again, making the labels all out of wack...

Why Is Sub Routine Not Firing
Feb 4, 2011I have the following code:
Private Sub Exceptionquery()
Dim connection As System.Data.SqlClient.SqlConnection
Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"
[code]....
I get the error Invalid Object name 'Scratchpad3' on this line:
adapter.Fill(ds)
I have tried to debug this and can see that the query is correct, that the values that are being passed to the sql server are correct but it doesnt look like my code is firing off the Exceptionquery Sub. I thought to call a sub all you had to enter was the name of the sub such as this line:
Exceptionquery()
I have also verified that the mapping of the buttonclick event is mapped correctly. I have other subs that I am calling in almost the same way and those work.

.net - Asp.net Event Handler Not Firing?
Apr 1, 2012I've been looking for a solution to this for several hours now and cannot find a solution.
The Scenario:I have a masterpage baseclass (called basemaster)All of my master pages inherit from basemaster
basemaster defines an event 'Public Event HandleClickEvent As EventHandler'I have a masterpage named master1
master1 defines an event handler 'Public Shadows Event HandleClickEvent As EventHandler'master1 has a user control named usr1 usr1 has a button that raises event ButtonClicked when clicked I have a page (thePage) that uses master1 thePage has a button click event handler that it registers like so: 'AddHandler Master.HandleClickEvent, AddressOf HandleTheClick' master1 has code something like:
Protected Sub Usr1_ButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Usr1.ButtonClicked RaiseEvent HandleClickEvent(sender, e) End Sub when thePage loads I see it register the handler on master1 when the button is clicked, Usr1_ButtonClicked is fired and I step through the RaiseEvent but HandleClickEvent on thePage is never reached.
.net - Page_Load Of Control Firing Twice?
Jun 18, 2012I am upgrading a 1.1 web app to 4.0 and am running into an issue with the page_load of a custom user control firing twice, both being treated as non-postbacks (IsPostBack is false in the case). I have read around and it seems that there are 2 culprits to this, 1 being an img tag without something in the src part (which there are no images on this page at all) or 2 an issue with AutoEventWireup and Handles being used at the same time. I have looked through all my code and there are no Handles keywords in there at all and AutoEventWireUp is set to true on every page, yet I still get this issue.

ASP Button Control Firing
Apr 20, 2012The problem im having is a little complicated to explain, so please bear with me. I have 2 button controls. In the page load, I wanted to know what button created a postback on the page load. Through research I have found this snippet below and it works as expected. So here is my scenario of events that occur when click on the button.
1. Click the button does a postback
2. Runs the function below and tell me the id of the button
3. Runs the clicked event handlers for that button [code]
The problem comes in when I click the second button, it does steps 1 and 2 but NEVER DOES 3. Through testing, I have that it only does 1, 2, and 3 on the first button clicked.[code]

Public Sub Main() Not Firing?
May 5, 2011I made my application single instance using the Mutex example from the codebank (converted to VB).
If I place
If Not FirstInstance Then Application.Exit()
in the Form_Load event of the main form, the form will show briefly before it is closed (on second instance). So I thought the way around this was by using Sub Main() (as I plan to add commandline support later), but the event is not firing with a MessageBox test. Where does this code need to go to avoid having the main form show briefly?
Converted Mutex
Public FirstInstance As Boolean
Public Mutex As Mutex = New Mutex(False, "<ID>", FirstInstance)
SelectedIndexChanged Not Firing In Asp.net Usercontrol
May 17, 2011.net 4.0, ASP.net, vb.net. I've got a usercontrol that is using an obout combo box. The obout is a cascading combobox that has 3 levels to it. when something it selected from the third level of the combobox, it is suppose to fire off a selectedIndexChanged event. This happens the first time that I select the usercontrol. The problem is if i want to go back and select something different. The selectedIndexChanged doesn't fire. I've set breakpoints and the AddHandler ComboBox3.SelectedIndexChanged, AddressOf ComboBox3_SelectedIndexChanged
runs just like it did the first time i select the usercontrol. But the selectedIndex just doesn't fire the second go around. Was wondering what i'm doing wrong. Here is the selectedIndexChanged that is not firing
