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.

Click to expand...

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)
 
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?

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.

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)
'///
