mouse scroll

[ThePentiumGuy]

under which event would "mouse scroll" go?
i want to check weather the mouse scroll moves up or down

 

[Merrion]

Hmm - if there isnt an event, checking for wm_mousewheel in the DefWndProc message would do it...

 

[Divil]

Controls have a MouseWheel event.

 

[DiverDan]

Sorry Divil,

I cant find that event in VB.Net...maybe its in C# only.

 

[Divil]

Its there, but for some reason its hidden. You can look up the signature for it in the object browser or the help and create your own handler method.

 

[iebidan]

I found it too... after MouseUp... maybe in VS.NET 2002 is hidden, but in 2003 is there

 

[DiverDan]

Youre right divil, its there but very hidden. I wonder why?
Could you post a sample of the event handler to give us VS 2002 folks a start.

Thanks
Dan

Im going from memory right now but those should be the right arguments:

Private Sub Form1_MouseWheel (sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseWheel

 

[DiverDan]

Okay, Thanks mutant...good memory!!

VB.Net 2002 has no help on this event at all!
How do I know if the mouse wheel is moving up or down?

Thanks
Dan

btw
this site gives out birthdays and ages... ouch for me!

 

[Divil]

Check out e.Delta thats passed to the handler.

Thanks again divil, that worked perfectly! This must have been a last minute addition that MS overlooked documenting.
