I am using Visual Basic 2005 Express and have 8 PictureBoxes on the Form.. When the user Double-clicks any of the Picture Boxes, the path of the image needs to be passed to a Subroutine..As of now, I have a different event for each of the PictureBoxes.. I was wondering if there is a way such that I can use a common event. i.e. if a user double-clicks on any of the picture boxes, the same event is raised ?
View 3 RepliesWithin my program, I'd like to allow the user to hold the CTRL key down while double-clicking with the mouse. Specifically, within the treeview control, I'd like to allow the user to be able to CTRL-DoubleClick but the DoubleClick event has the EventArgs parameter that doesn't provide any keyboard data.I'm guessing that this is possible, but I'm just drawing a blank on how to implement it.
View 5 RepliesI'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:

am trying to call a very lengthy set of code from under the DoubleClick event of one control, from within the Click event of another control....without having to copy and paste the desired VERY length code from the first control into the second.

View 1 RepliesI am developing a form application in VB .Net with a main thread and two other threads that reading values from two serial ports, do some work and raising events to return values when each thread ends.The handlers for the events are in my main thread.Is there any possibility the two threads to raise events the same time or some other event (button click event for example) raised the same time with a thread finished event? What happened then? Is there a way to make asynchronous event raising?

View 2 RepliesAs it stands, when I click a button to load the data the application lags and looks as though it has locked up although it has not. There are a lot (10,000) of records to load in some cases.
I thought I could just change my status strip text to dispay "Loading database" while it's loading.
So, I raise an event (dbloading) in the "load db" button.click event before calling the procedure to load the data. When that event is raised, I change the status strip text.... but it does not work.
Here's my
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click

i have a databound datagrid in vb.net 2008. This is a program where i use the double click event multipal times.. but for some reason on a new form it's not working anymore. In code behind i selected the datagrid and double click event. when i double click on teh grid in debug mode, it never fires off the event(i put a breakpoint in). I've tried several other events and none of them are firing.
View 1 Repliesi'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events..

Problem that you may have when dealing with two objects that are raising some events. Here, to make it obvious, I am closing the form, but the problem can be experienced with any other 2 classes event. First, what is the problem !
Let suppose that by pressing a button, you want to raise a custom event, then execute a method and then close the form
In that case, you may use a code similar to this
Event BeepIt()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent BeepIt()
