.net - Form.Load Event Not Firing, Form Showing?
Nov 9, 2010I fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

VS 2010 Form Load Doesnt Work If I Delete A RadioButton
Oct 16, 2011This is the strangest thing, I can not figure out why this is happening. When I delete a radio button from my form which is used to filter data in a database Form_Load stops working.My project consists of a database and a web browser. The database has a search filter options.[code]For some reason it didnt load my settings on start up. I made a button which displayed True/False in a text box to check if it was saved in my settings, it was, it just didnt want to load. So I deleted it and everything broke! Nothing in the code is referenced to the RadioButton or its code.
Have I done something wrong or is VB just messing with me? There is obviously a bunch of more code, I just posted what I think is relevant to the issue. If you feel something is missing, tell me and Ill post it. ied to change the RadioButton with a CheckBox, and I changed the code from "Me.ExampleTableAdapter.FilterHide..." to "Me.Example TableAdapter. Fill...", which is the same as in Form_Load. It works if it starts checked. If I remove this code or delete the CheckBox nothing works even though the same code is in Form_Load. If I start off with the CheckBox in an Unchecked state nothing loads, if I check it everything except the Browser works for some reason.

UserControl MouseLeave Event Not Firing On Form?
Apr 16, 2012I created a little usercontrol that looks similar to Visual Studios toolbox. It works great in the user control project, but when I import it to a form the MouseLeave Event doesn't work. The MouseEnter event works fine however. Any idea why only the MouseLeave event doesnt work? I did notice that I have to use the Panel controls MouseLeave, MouseEnter events for things to work correctly. The Usercontrol Mouseleave and Mouseenter didn't work at all.

Application Firing Shutdown Event On Form Close?
Sep 10, 2010I have a login form that when the user clicks OK and logs in successfully it loads the main application form.However when I show the main form and close the login form, the app is firing the shutdown event.Is this because the app thinks that the login form is the only form open and thus fires the shutdown event?Here is the code for the login routine, when I call Me.Close() at the end is when the shutdown event is fired. Am I doing things out of order? I used to do it this way in VB6 with no problems (I know they're a lot different).Note, it's nothing in frmMain either, this happens no matter what form I try to open.
Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click

View 1 Replies.Net Form Activate/Deactivate Event Firing Issue After Removing A TabPage From TabControl?
Nov 28, 2011I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

View 7 RepliesWebbrowser Control Documentcomplete Event Not Firing When Iframe Does Not Load?
May 23, 2008First off I hope I'm in the right forum.I have an application I built with the WebBrowser control in Visual Basic 2005. I am using the DocumentComplete event to track when a page has fully finished loading as some of the webpages I need to work with have frames.
The problem I am having is that when some iframes time out or don't load, the documentcomplete events stop firing. So if my webpage has 2 frames on it, we'd expect 3 documentcomplete events. One for each frame and one for the parent document once the frames have loaded. If say frame 2 does not load properly, the documentcomplete event for the overall document never fires.
What Happens Before Form Load Event
Dec 21, 2011I have a form and initialize some global variables on its Load Event. There is a TextChanged event in one control (a textbox) that uses that value. The TextChanged event of the control is triggered before the Form's Load event even if I do not change anything on the TextBox, it looks like that happens when the control is loaded. Why is it doing it before the form? and what event can I trap in order to assure it's the first thing that happens?
Its as simple as this:
vb.net
Private Sub PackOutMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ActiveFlag = False
[Code]....
My guess is that the msgbox should not appear until the flag is set to true somewhere in the code and then change the contents of txtUser, but it is shown before the form.

View 1 RepliesForm's Load Event Not Called?
Apr 25, 2011I was having a problem with the debugger not stopping at breakpoints. After a lot of work that yielded no results, I realized that the problem was occuring in the form's load event and subs called from that event.
The problem is that it appears that the load event is not being called. Other startup forms in other projects in the solution seem to be working ok.
what could be keeping the the Load event from working?

VS 2010 Event Before Form Load?
Apr 30, 2011so I have the following
Try
Dim username as String = My.Application.CommandLineArgs(0)
Dim password as String = My.Application.CommandLineArgs(1)
Catch
Msgbox("Cannot launch")
Application.Exit
Exit Sub
End Try
I placed this in the form's load event. What I want is for this check to run before the form even loads.If an error occurs, the msgbox comes up and the form is never seen. When I try the code now, the form comes up the msgbox shows. When the user clicks OK the form closes. I tried placing it in the form's designer but the designer tries loading the form any way. How do I get this check to run before the form shows?
