I'd like to temporarily disable events for a given control. For example, the SelectionChanged event on a combobox might be used to update a display every time the user changes the combobox... but while I'm filling the combobox with values, I don't want the SelectionChanged event to be firing over and over... I need to disable events while the combobox is being populated. How do I do this?

Can you temporarily disable a radio buttons CheckChanged Sub? I have a set of radio buttons in a groupbox and when the user selects one, I need to check if it's a valid selection. If not, I need to reset it to the previous button that was pressed. Below is an example of my
Private Sub rbGame_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbGame.CheckedChanged
t_indextype = m_indextype
m_indextype = "1"
[CODE]..................
In the above example, ResetButtons() changes the checked value of the radiio button selected to false and changes the checked value of the previous radio button to true. The problem is that when radio button rbGame gets changed, it causes the CheckChanged sub above to run again from the top. Is there a way to temporarily disable it from running while I make my changes and then re-enable it?
I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

These changes cause events to fire causing data (mostly null when the first event fires) to be saved causing errors.

I have a dialog that gets called from time to time. It is only created once, and then shown or hidden. Depending on the current conditions, when I display it, I need to disable the controls on it so that the user does not make any changes.I have code that checks the condition and sets the enabled property to false for the controls. There is a DataGridView control on the dialog, and for some reason, it stays enabled and allows changes. Does anyone know why, or what I need to do to get it to not accept any input?

View 3 RepliesI have been googling for hours and trying to figure this out, and I just can't.I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com"), it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly apparent especially on pages like forums or craigslist.

View 2 RepliesI had a form (says form A)with control on it, 2 buttons with text "View Process Flow"(Button1) and "Manual trigger Process"(Button2). Both button will load and shows Form A in Panel1 in Form1, but button1 will let user to see the action but block them on clicking on it, button2 will let User see and clickon the control.
In other software, I can use a transparency button or form block User by acess formA(so, they can see,but not click), But VB2008 transparentcy option kind of idiot(Or i dont know how to use it?)seem it just change the control back color to parent's backcolor(totaly useless, and the "tranparen key" as well)
I cant disable control cause it will stop the animation, only ways i can think off is add in a IF statement in every button, so it will do nothing when viewing = true.
I have my numeric up and down control set up but there is one problem. When i run the application, there is an IBeam in the value box.

I have tried the read only setting but the beam is still there.

View 4 RepliesI just opened up an Asp.NET project solution for some maintenance. I usually use C# but this project is in VB. When clicking on a form's button and looking at the properties view, I see no way to view the events for that button. Usually the lightning bolt button would be present in the properties view and clicking it would show all events for the control. From there you could see the event handlers or create an event handler by double clicking. Why don't I see that in this project. Is it an IDE setting or a VB project thing?
P.S. I thought I was in VS 2005 but it's 2003. 2003 usually shows me the lightning bolt though in my c# projects.
