I don't really know how to call this...Anyhow... I have two objects (for example, "A" and "B") of the same type/class. I have an event (for example, "Refreshed") in both objects. Is it possible, that when "Refreshed" fires in "A", it also fires in "B"?
Edit: forgot to mention - "A" and "B" don't "know" each other.
I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part.

I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?

I need a single, global OleDbConnection. One which will be available to use throughout my app/project. Another project like a custom UserControl?

I'm using a DGV to show some data & I'm using the CellClick event to run some code when the user clicks on each row. But I also want to run some other code if the user double clicks a row, but the CellDoubleClick event never fires, the CellClick event just fires twice. Does anyone have any ideas on how to make both events work?
View 1 RepliesI have a base object, with a event that can be triggered by multiple methods.Then I created a child object that inherits that base object. I want to be able to trigger that event in the new object; but I can't use RaiseEvent to raise a base-object's event.To get around this, I created a small method in the base object that takes the argument for the event and I just use it to trigger the event. Is this the proper way to handle this situation? Similarly, I could Shadow the event with a duplicate one in the child object.Is there a standard way to handle events across inheritance?
View 2 RepliesIs it ok for me to have this event - firing on TextChanged for my BillingSame textbox

I've got a series of textboxes that are bound to a dataset. I've got them disabled and will be hiding them. Then I have a series of check boxes related to each textbox. The user clicks the check box and I change the value of the databound textbox. Nice and easy way to bind check boxes to DB fields. Any way to create these relationships at runtime - basically creating the events that I'm hardcoding right here.
Private Sub IntprtLead_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles IntprtLead.TextChanged _
, IntprtCheck.TextChanged _
, IntprtCons.TextChanged _
, IntprtSimul.TextChanged
Dim strValue As String = TryCast(sender, TextBox).Text

I know I can loop through the controls on the form and find these "named" objects easily enough. Is it possible to have more "generic" event code and then create the handles relationships at runtime?
