.net - Mousewheel Scroll An Usercontrol?
Mar 4, 2009I have a usercontrol I created. I added a panel and a vertical scrollbar to the right of it. I'd like to be able to scroll it with the mousewheel. The problem is there doesn't seem to be any events that fire on mousewheel. If I take the panel off then the usercontrol has focus and it will fire on mousewheel in the form. But with the panel on it doesn't seem to fire the mousewheel event of the panel, or the usercontrol within the control or even on the form. The best solution would be to have an event fire in the usercontrol but I'd even accept an event on the form and feed it back into the usercontrol.
I'm using vb.net and vs2005 if it matters.

Mousewheel Scroll In Panel With Dynamically Added Picturebox Controls?
Dec 2, 2009I've dynamically added 20 pictureboxes to a panel and would like to see the panel scroll when I use the mouse wheel. To implement this I have tried to set the autoscroll to true on the panel control. Here is the code.
For i As Integer = 1 To 20:
Dim b As New PictureBox()
b.Image = Nothing
[Code]....
It works for "button" control, but not for the "picturebox" or "label" controls?

Disabling Scroll With System.Console.Write?
Apr 11, 2009Is it possible to use Console.Write to place a single character at the very bottom right of a typical 80x25 console, without having the console scroll the row up? This is the code that I'm using...
Imports System
Console.SetCursorPosition(Console.WindowWidth-1, Console.WindowHeight-1)
Console.Write("x")
This is not working like I would like it to. Any suggestions or alternatives? I've tested that SetCursorPosition does use a 0,0 coordinate system, already. Using the WindowWidth-1/Height-1 should put me in the lower right corner of the screen... which it does, but then Console.Write is putting the "x" down and continuing on to the next line.

View 2 RepliesInterface And Graphics :: MouseWheel For Interop'ed ActiveX Control?
Apr 18, 2011Is it possible to get the MouseWheel event from an Interoped ActiveX Control?
I have a DXF Viewer (with measure) control I wrote in VB6 that is quite frankly... Huge. It would take an inordinate amount of time to rewrite the whole thing and supporting tools in VB.NET. The MouseWheel event is used to Zoom in and Out. The control has a MouseWheel_Input() method to accept MouseWheel data from the host.
I added all the VB6 Mouse events, the Enabled Property, and The ActiveControl Property in VB6. Recompiled and registered the control on my VB.NET development machine. Added the control to my new VB.NET project and verified it has a focus method.
