View 3 RepliesThe 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.

View 5 RepliesI have a tab control with two tab pages. One page has the auto scroll enabled since there is to much content in the page. The middle mouse wheel doesn't scroll the scroll bar; I have to actually click and hold the scroll bar and drag it down to scroll. Is there a property to allow this?

View 16 RepliesTo 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). But how do I detect tilting of the wheel (tilt to the left/right for horizontal scrolling)? Neither OnMouseWheel, not OnMouseDown is being called when I tilt the mouse wheel.

View 2 RepliesIm trying to implement mouse emulation of multiple devices for mouse mischief from a vb.net application that will be run as a service in the background later. I just need to either simulate adding the mouse devices or pointers to screen and the send a left click for each user.
View 10 RepliesI have a problem with a purchased UI control, and to do a quick and dirty fix (no time to build/order a new control), I need to emulate a click at the right side, say 10 pixels into the control, from the right side of the control. Is that possible in vb.net? We can't do this functionality programmatically, due to a bad API design. And now time is running low.
Which method do I use to get the coordinate to perform the click at, and what code do I use to do the actual click? The code should move mousepointer to the location, do a right click and then return to where it was, hopefully without the user ever noticing anyting.
I have one form that display records and I use BindingNavigator to navigate trough the record. I want use also the wheel mouse to go up and down to the record, it's possible do this?
View 3 RepliesDoes 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 12 RepliesI 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 RepliesI 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.
- Disable the wheel, if focus is ON DataGridViewComboBoxColumn ?
I 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.
I am trying to make a program that AUTO left clicks the mouse according to a set second interval (This will be repeated in a loop) What I got so far is test event going on because of course you have to brake the loop somehow and stop the emulation of the left mouse click.
I have on my form a Text box and I dont know how to go about this. I want the Keyboard buttons A & S to be used to start and Stop the Loop and the Textbox to take in the input form the user in seconds.. and loop it until the user pusses S to stop..
1).. Use the Textbox on the form to let the user input the time interval between clicks...
2).. Use The Keyboard's (A) Key to START the program's Double Left Click Loop.
3).. Use The Keyboard's (S) Key to END the program's Double Left Click Loop.
4).. The Program MUST INFINITY Loop Mouse DOUBLE Left Click (UNTIL USER Presses (S) Key) (A=Start, S=Stop)
5).. The Emulation of the Clicking itself has to work in all Windows Maximized or Windowed Full-screen even on the desktop or within other programs like games. (EXAMPLE: Can run when a game is running at Full screen or windowed.
I'm sorta confused on how to do this seeing that I never dealt with emulation or events with the mouse itself. However I do know that there has to be certain key press events and a true or false statements placed in code.

View 1 RepliesThe code given below works fine. The only problem is mouse wheel/keyup cannot be used after the TOP image is displayed, it fills the keyboard buffer. Then I have to wait awhile to use wheel/keydown. Also the images after wheel/keydown goes beyond last image. It should stop at the last image like it stops at the first image.

My application uses a trackbar to sort images.It works best if the mouse wheel scroll lines value is one.I can advise my users to set the value themselves in the control panel having determined it is three, but I cant set a users scroll value to one for them.I would like to have some visual basic code in the form load that sets the scroll line value to one.

View 3 RepliesI'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?
After scouring the articles online I have come up with this design for a winforms based touchscreen app that needs smartphone like scrolling. The app itself will run on a tablet laptop or touchscreen desktop.I put everything I want to scroll on a panel. Set autoscroll to true (which will show scrollbars)Now put this whole panel inside a groupbox.Shrink the groupbox until the scrollbars are hidden (visually hidden, not visible = false)
Now the fun part I am stuck at.I think I have to handle the mousedown, mouseup & mousemove on the panel to set the autoscrollposition so that when someone touches the panel and drags, it does it's scroll magic. Please help fill in the few lines of code in below method stubs. The msdn doc on autoscrollposition is very confusing since it returns negative numbers but needs to be set to positive with abs and what not.

I have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.
