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?

View 2 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 3 RepliesMy 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 5 RepliesI am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visible so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.

I am having an odd problem with the Horizontal Scroll Control in my program.I am using it to scroll a series of panels across a form.This is my code:
Private
Sub scrHoriz_Scroll(ByVal

The problem is that this works perfectly if I use the left and right arrows and it also works perfectly if I use the scroll bar's slider SLOWLY. If I scroll using the slider and move it quickly then the scroll gets out of sync.The small change and large change are both set to 1 and maximum is set to 8
I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.
View 1 RepliesI have a form in VB.Net with Autoscroll enabled and several ComboBoxes within it. When I click on a ComboBox, I can use the mouse wheel to scroll through options, but I cannot deselect the ComboBox (by clicking off it on a blank portion of the parent form) in order to return to scrolling the parent form. This makes navigation in the form annoying, as I instinctively click off the control and flip the scroll wheel, causing the ComboBox to change selections instead of moving the parent form.
Is there a way to make this work in the intuitive way I expect it to, or do I have some conceptual confusion that makes this the wrong question to ask?
Is it possible to emulate a mouse wheel scroll up/down with VB?
View 3 RepliesI am overriding the WndProc to capture the WM_VSCROLL of a textbox / RTB... However this does not seem to capture the scroll event if it happens from a scroll wheel of a mouse ... how can i pick this up?... i can't use the MouseWheel event because this occurs when the mouse is scroll wheel is actually turned and not after the content is actually scrolled.
View 7 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 form which has a horizontal scoll bar, a vertical scroll bar, and a panel. The 2 scroll bars move the panel. When I execute the form, the panel will scroll under the horizontal scroll bar when using the vertical scroll bar. But it scrolls over top of the vertical scroll bar when using the horizontal bar. I don't understand why 1 of them goes over and the other 1 goes under. Is there some property that controls this? Or some way to that 1 set it up wrong? The vertical scroll bar is on the left edge of the form , to the left of the panel, and the horizontal scroll bar is near the top of the form, above the pane. Can anyone direct me as to how to get it to stop scroll over this bar?

I 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 4 RepliesI have a textbox that shows events on a program, which I add.

I'd like the newest, most recent events to appear at the bottom of the textbox, and to have the user not have to scroll down every time something new is added.
View 2 RepliesWell un-like the textbox when AppendText() is used, the box doesn't auto-scroll down to the end, now I already know about caret position scrolling & all that but if I use it it seems to scroll slightly past the endline about enough to show yet another line if there were one.Now I was going to use code from a post I had inquired about similar but it's not working here in vista(SendMessage function) isn't functioning at all, it says the endpoint wasn't found, I guess meaning the function in the .dll wasn't found to be used.url...It was originally for a textbox to retain position if your not scrolled down to the bottom, which I want to keep such functionality in a RichTextBox but make it scroll to the bottom otherwise(hopefully not the slightly too far problem I have with caret position now...)

View 2 RepliesI am creating some help files by using a TabContol box, on one of the tabs I need to have the scroll bars to be able to scroll down to see all the info.In nearly all software packages that I know of, you can also use your mouses' scroll wheel to move the scroll bars. This is not happening for me in this particular situation. I have looked for a setting in the TabControls properties settings, but cannot find anything to enable the mouse to move the scroll bars.
