May 22, 2012

I 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?

VS 2010 Invisible Webbrowser Control Mouse Focus Stealer?

Dec 16, 2009

I wanted to know if there is a way to stop my webbrowser control from steeling my cursors focus? i mean its bad enough i have to hear the god damn thing in the background as it refreshes the pages.

What i built is basically a program that checks my marks on my school website and verifies to see if any new grades have been added. The program then notifies me by sending a text message to my phone. The program is in its beta stage and has lots of sloppy logic and code. anyways i hope someone knows how to keep my focus from running off of msn when I'm trying to type.

And as for the variables and coding. i know i have made it sloppy with unnecessary variables. I'm planning on cleaning that up when i have the time.

Detect Mouse Wheel Tilt?

Jul 5, 2009

To 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.

C# - Shift + Mouse Wheel Horizontal Scrolling

Oct 19, 2011

The 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.

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.

Use Mouse Wheel In Multi-line Textbox?

Aug 24, 2009

I 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?

VS 2005 - Disabling Mouse Wheel On A DataGridViewComboBoxColumn?

Sep 14, 2011

I 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.

Working With Mouse Wheel Not Moving Constantly

Feb 15, 2011

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.

.net - Using Mouse Wheel And Up Down Keys To Navigate Images In Imagelist?

Jan 17, 2012

The 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. Code courtesy of Geek On Demand.

Forms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?

Feb 16, 2011

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Lost Focus Event, What Control Is Getting Focus?

Mar 21, 2012

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!

So for example something like this...

Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then
