View 3 RepliesC# - Shift + Mouse Wheel Horizontal Scrolling
Oct 19, 2011The use of shift + scroll wheel is fairly common for horizontal scrolling.
Both of those are fairly easy to capture. I can use the MouseWheel event with a flag set by the KeyDown, KeyUp events to keep track of when the shift key is pressed.
However, how do I actually trigger the horizontal scrolling? I am aware of WM_MOUSEHWHEEL, can that be used to trigger the event?
Update: For a System.Windows.Form there is a HorizontalScroll property that is of type HScrollProperties. You can manipulate the Value attribute on that object to change the horizontal scrollbar's position. However, so far I haven't spotted any other controls on which that object is available.
Disable Mouse Scroll Wheel In Combobox?
Jun 3, 2010Does anyone know of a way to disable the mouse scroll wheel when a control such as a ombobox or listbox has focus? For my purposes, combobox is all I need the answer for.I have a combobox set to trigger a SQL query on SelectedIndexChanged, and accidentally scrolling the wheel while the combobox has focus causes about six SQL queries to fire off simultaneously.

View 2 RepliesVS 2005 - Disabling Mouse Wheel On A DataGridViewComboBoxColumn?
Sep 14, 2011I have an unbound datagridview, where column #3 is a DataGridViewComboBoxColumn which is filled with some values for the user to choose.
Problem: mouse wheel.Users usually use the mouse wheel to scroll the datagridview. That is fine.However, if the focus is on a ComboboxCell, the wheel will not do the intended function (scrolling the grid), but will scroll the combo and change the cell value.
I am having lots of accidental changes because of that.

Jul 5, 2009To detect rotation of the mouse wheel in .NET/WinForms, I can override OnMouseWheel. Clicking can be detected by overriding OnMouseDown (it's just the Middle button).

Aug 24, 2009I have a multi-line text box with hundreds of lines. I would like to be able to scroll up or down in the list using the mousewheel (much like using the pgup/pgdown keys). I think I need to use the .mousewheel event, but I'm not sure how to implement this. Is that supported out of the box, or do I need to hook the mouse?
View 2 RepliesWorking With Mouse Wheel Not Moving Constantly
Feb 15, 2011I was getting some slightly unusual behavior when using the mouse wheel for some zooming/scaling work (only vaguely related to the earlier thread, for those who remember it). Frankly, it is likely that I have a bug in some code, but that wasn't quite enough to explain what I was seeing. Therefore, I used a error logging feature in my app to note the delta being passed in each Mouse Wheel event. I then ran the app and gave the wheel one good spin, which was about the maximum that I would normally ever spin the wheel in one steady, continuous motion. I wasn't going slow, I wasn't going fast, and I rotated it about as much as my finger comfortably could in a single roll.[code]I then rolled it back the other way using the same motion, and got 8 events, mostly under 200, but one of them was -331 and the other was -7940.
After a handful of tests, it appears that the wheel event is raised often, which is no surprise, but that the values fluctuate all over the place. With a continuous rotation, or as nearly continuous as I can make it, I can see a series of events with one of them easily being ten times the rest.The problem this presents is that the scaling I am using is not smooth (nor is it standard mathematical scaling, but that's a different story). Each zoom level doubles the size of the objects relative to the previous level, though the distance between them stays the same. I would like to do this by dividing the delta by some factor, and if that is above a threshold, increase the zoom level. That won't work smoothly, in this case. If I make the factor something small enough that I pick up a small rotation, then any larger rotation is likely to include a delta that takes the screen through all zoom levels in a single step. Alternatively, if I make the factor large, then all smaller rotations are simply ignored.One option would be to filter out rotation values below 200 and above 800, or so. I am looking for other alternatives.

VS 2008 Disable Scroll Bars But Enable Scrolling?
Feb 4, 2010I am building a basic web browser that I would like to not have any scroll bars (I can do this by setting the "ScrollBarsEnabled" button to False) but also still be able to have the scroll fulction via keyboard shortcuts.
IE when you press page up and down the page scrolls, but when they are disabled you can no longer use the page up and down keys to scroll.
Is there any "scroll function" in the browser like WebBrowser1.scrolldown etc that I could use? that I can have key strokes trigger?
A bit of an over view, the web browser is hosted in other software that has customizable buttons, these buttons can be set to send key strokes to the hosted app in this case my web browser.
Example of what I do for my home button
Private Sub browser_homebutton(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles browser.PreviewKeyDown
If e.KeyCode = Keys.H And e.Modifiers = Keys.Control Then

View 3 Replies.net - Make Mouse Tilt Horizontal Scrolling Always Repeat?
Jun 12, 2012I'm designing a form with a horizontal scroll bar docked at the bottom. I wanted to add support for side-scrolling using mouse tilt buttons and found this solution which, after a bit of tinkering, seemed to do the trick - that is, while the form only had GDI graphics drawn on its surface.
However, since then I've added some controls to the form and found that when the mouse is over any of them the tilt operation only fires once-at-a-time instead of repeatedly as it does when the mouse is over any other part of the form.To see what I mean (if you have a mouse with tilt buttons) dock a horizontal scrollbar onto the bottom of a form, add a few other controls and paste in this code:
Public Class Form1
Const WM_MOUSEHWHEEL As Integer = &H20E
Protected Overrides Sub WndProc(ByRef m As Message)
[code]....
You'll see that side-scrolling repeats when the mouse is over a blank part of the form, but only "one-shots" when it's over a control.I'm guessing the solution lies somewhere in the message's .Result value, but I'm at a loss as to what that should be. In fact I'm not even sure I'm returning a correct value anyway because the code in the original solution threw an exception to the DirectCast function so I swapped that for CType, which seemed to work okay. I've tried working it out using Spy++ but I can't see anything obvious.
UPDATE:I've noticed when I include 'Child' windows in Spy++ there are two (0x020E) messages and two return values, 1 then 0. I presume the message is being passed onto the control by the form. So I guess the question now is: can the message be prevented from being passed to the control? Or can the control's return value be intercepted and converted to 1?
Disable Mouse While Mouse Is Over WebBrowserControl?
Jun 11, 2009I have a WebBrowserControl on my main form and it auto navigates and all that just fine! What I would like to do is not allow the user to click anywhere within the WebBrowserControl while the program is running. Reason for this is that the browser self-navigates to a view of cameras and this shows scrollbars. My program then takes screenshots of specific coordinates on the screen so I do not want the user to use the scrollbars or highlight or do ANYTHING to the page once the program starts. I would like to change the cursor icon to like a red X or something similar to indicate no user functionality.
