I 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 visable 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.

View 2 RepliesMy listbox has 19 lines, Is there a way to scroll down and show line 20-39 when I click a button? My application is designed for a touch screen so it is impracticle to use the scrollbar.
View 2 Replies"Automatic Image-scroller". The scenario is quite simple. I've got one single picture, and it should move up and when it moves out of frame, the same picture would appear beneath itself and continue to move up. Kind of a loop.The problem is that i haven't got a single clue how to make it in code-behind nor XAML, but it has to written in "code-behind" cause of the things i'm hooking it up with.
View 1 RepliesIntent: To teach the user how to create a control that scrolls text at an adjustable speed across the control.What you'll need:Visual Studio.NET (2002 or 2003) - The version I built this with is 200325 Minutes of free timeI don't remember what prompted me to create this control, except that I was sitting at my desk one day and thought to myself?
1. First open the Visual Studio IDE.
2. Select 'New Project'.
3. From the project languages, select 'Visual Basic'.
4. From the project types, select 'Windows Control Library'.
5.Once the initial project has finished loading there's a couple of things that you may want to do first. The first one being, change the control name to something that means something. "UserControl1" just won't do, so in the 'Solution Explorer' right click on the "UserControl1.vb" file and click 'Rename'. Without removing the '.vb' file extension, type the name of the control. In this case lets call it 'ScrollingMarquee.vb'.
6. Now back to the control design area. Add a timer control to your project from the toolbox. Set the enabled property to 'True' and set the interval to 100. Right click on the control area (the actual control itself, not the timer) and click on 'View Code'. This will take you to the code area of project.
7. Enter the code as is written displayed below.
Code:Imports System.DrawingImports System.Drawing.Drawing2DImports System.ComponentModel
Public Class ScrollingMarque Inherits System.Windows.Forms.UserControl
#Region " Windows Form Designer generated code "
[code]....
Just want to make sure that each time we move the control or resize it,'it re-renders correctly.Invalidate()End SubEnd Class8.Next select 'Build -> Build ScrollingMarquee'.9. Once you have any bugs worked out (there shouldn't be any, but in case there are), you can change the build mode to release and rebuild the control for use in your projects.
I am navigating to a website using a webbrowers control and I wish to automatically scroll the page after it is loaded. I have used scrolltop , scrollleft commands as set out below but nothing seems to happen.
WebBrowser1.Document.Body.ScrollTop = 100
WebBrowser1.Document.Body.ScrollLeft = 200
I have placed the above commands in a command button and wait until the page has loaded before I press it and also in the
WebBrowser1_DocumentCompleted sub
Other commands such as
WebBrowser1.Document.Body.ScrollIntoView(True)
Seem to work ok.
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.

Point mouseUpPoint;

I'm having a tough time implementing my own custom control that makes use of scrollbars if needed. The whole control itself would not be scrollable and only some portions of the custom paining would be scrolled, so the AutoScrolling capabilities of ScrollableControl would not work for me. But, I'm having an extremely difficult time in implementing a professional looking solution, where as the control gets resized, the scrollbars resize proportionality to be able to show a specified area.
View 1 RepliesI have set a scrollable control's autoscroll to true. What do you do when you don't want a scroll to occur? For example, suppose you have a RichTextBox and a button side by side as below:
Notice that "button1" has the focus. If you click on the RichTextBox to give it focus, the scroll bars will scroll until the upper left corner of the RichTextBox is in view.
But what if, for whatever reason, you wanted to keep button1 in view? How would you do that?
I am wanting to enable scrolling via Page Up/down keys, arrow keys etc as well as using a multi-touch touch screen (just need to drag your finger any where on the web browser control), but I do not want to be able to see the scrollbars. All of this works when:
WebBrowser1.ScrollBarsEnabled = (True)
But if I set to false it disables not just the scroll bars but also scrolling. Does anyone know a work around to this?

I have a ListBox Control containing 5 items. This control displays the current condition and allows the condition to change. The ListBox.SelectedIndex is calculated from the current condition (normally item 2 in the list) and displayed. If the user requires to change this condition the Keyboard Up/Down would be used for navigation (The App is very keyboard intensive), however if the ListBox.SelectedIndex is set at 2 and the keyboard down arrow is pressed the selected item displayed changes to 0 not 3 as required. Is there a way to synchronise the keyboard control with the current selected index?

I thought I'd embark on a little project, just making a registry editor as the one on WinXP is a little..

View 1 RepliesI'm writing an application; I have an Advanced Tree control and a ListBox control. When I populate the ListBox programmatically, using a function that returns a ListBoxItem, it adds the field fine, but displaying incorrectly; it doesn't just add say "My item," it adds "ListViewItem: {My item}"
When I add the item using just a string, it adds fine but I need to use the return function to set the tag data and such, but when I use that function, it adds the above which is really annoying.
