handling mousedown for dynamic pictureboxes

Hi,

I'm using visual studio dotnet 2002 programming in vb

can anyone tell me how I can handle the mousedown event for pictureboxes I
create dynamically at runtime?
I've tried setting the mousedown to handle mybase.mousedown but it doesn't
detect the mousedown event until I move out of the pictureboxes I have
created (only works on the part of the form where I don't have any
pictureboxes). I also cannot set the mousedown event to handle my array of
pictureboxes as they are not a valid handle.

regards,

Scott M.

Have a look at the AddHandler and RemoveHandler keywords.

Hi, you can use AddHandler to add an event handler for an, erm, event :)

'///
AddHandler MyRuntimePictureBox.MouseDown, AddressOf MyMouseDownHandler
'///


Public Sub MyMouseDownHandler(ByVal sender As Object, ByVal e As
MouseEventArgs)
.
.
.
End Sub

Hi again,

okay follow up question:

now that I have handled the clicking of one of my array of pictureboxes, how
can I tell which picturebox within the array I have clicked on?

regards,

Scott M.

Hi Scott,

The sender argument of the event handler will be the PictureBox that was
clicked. It's defined as an Object, so cast it to a PictureBox and then loop
through your array until you find a match.

Regards,
Fergus.

=============================
Public Shared Moan
Sender - now what kind of name is that ?
I've never read Sender and thought "ah,
that must be the control that the event
occurred with/in/at/to."
End Moan

Hi, your attached method has a sender argument, which can be casted to the
PictureBox which was clicked:

'///
Dim pbClicked As PictureBox
If TypeOf sender Is PictureBox Then pbClicked = DirectCast(sender,
PictureBox)
'///
