Enable PageDown, Pageup, PageLeft, PageRight Region On Scrollbars?
Oct 14, 2011
I seem to remember a time when application scrollbars had clickable "scroll Page" buttons on them. What happened to them?
Do they still exist? If so, how do I make them visible?
I've written the code shown below to investigate the vertical scrollbar and it seems to indicate that a region is still defined for this function, but that it has been set to invisible (just paste code to Form1 code on a new WinForm project). I've searched for information on this but have come up empty handed.
I know that I could implement this feature myself with additional controls, but I was just curious if it could be done using the existing framework.
Imports System.Runtime.InteropServices
Public Class Form1

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?
To refresh or invalidate only a region of the form.sometimes I will need refresh all the form, but in some situations only specific regions of the form..I saw some samples on the Microsft site, but I don't understood.I use VB .net 2008
I want to allow the user to enable or disable a textbox by clicking either a button (enable) or the reverse. (disable) if the user clicks the enable button the textbox should receive the focus.
i can't find a way to add scrollbars to a picture box when loading a image and the image is greater in size than the picturebox, to have the picturebox add scrollbars to view the rest of the image..so much work to do and so many choices to choose from...
[Using VB.NET 2010 / targeting the .NET 2.0 framework]I'm getting some unexpected behavior with panel scrollbars, and was wondering if it is a bug, or simply something that I'm failing to do correctly.Basically, I have a panel with Autoscroll enabled. Then I put some other items inside the panel, and then make the panel smaller, so that the panel's scrollbars appear.
Outside of the panel I have 2 buttons -- named "scrollOn" and "scrollOff", which turn the panel's scrollbar's on and off using the "Autoscroll" property (for example the "scrollOff" code I'm using is Panel1.AutoScroll = False ).
So after I run the program, I move the panel's scrollbar down a little bit with the mouse (this part is necessary to reproduce the bug). I then click the "scrollOff" button (which should make the scrollbars disappear). But when I do that, the scrollbars are not only still visible, but they "freeze up" (can't move them with the mouse anymore).
I have a custom-shaped form created by setting the Region to an image. I want to be able to highlight the edge of the form when it has focus. To do this I believe I need to get the outline of the form and convert it to a path so I can draw a two-pixel highlightaround the edge of the form.
How do I set the scrollbars in an ASP.net page dynamically? When a user comes to certain pages on my site I would like the page to be scrolled down about halfway. Is there a way to do this without using Javascript?
I am using a flowpanellayout. I want to scroll the panel, but not using the scrollbars. (We are going to use a touch screen). I am going to use button to scroll up and down. How can I control that?
I have 2 richtextboxes on a form and I want to link their vertical scrollbars i.e. ifrichtextbox1's scroll bar is moved then richtextbox2's scroll bar moves by the same amount.The reason for this is that both richtextboxes will contain almost identical text barring a few differences in the second richtextbox. By linking the scroll bars my hope is that the user can better compare the textboxes for any differences between them. I have looked at trying to find a scroll bar property but can not find one. Does one exist?
I have MDI parent and child windows that were working fine but now clicking on a dropdown doesn't do anything, also scrollbars cannot be moved. Other controls are still ok, buttons and other links are still working. I should also note that if I change the child to load in a separate window all the controls work again.
the scrollbars still appears when i load project i try adding it to a commandbutton and wait till webpage loads and then ScrollBarsEnabled = False but nothing works..
I have a LIstView to display four columns. I have fixed the width of LIstView to 400 and this width is divied proportionately amongst the four columns . The code is working perfectly. The problem is with the horizontal bar on the bottom of LIstView. When the number of records to display in LIstview acceed the height of LIstView, the horizontal scrollbar hides some digits of the last column of listview and i have to scroll to right to see the whole contents of last column. settings in Properties Window or the code for seeing the entire last column without scrolling the horizontal scrollbar at the bottom of LIstview.
i have never used a UserControl in the following manner:In need to make a UserControll that can be put in a list of them depending on how many the user chooses and then if there are more than 4 to have a Vscrollbar to scroll through them.
"Is it possible to use one ScrollBar to set different Values in 2 more scrollBars? In the code that follows, I want to use Frequency 1 ScrollBar Value to set Frequency 2 ScrollBar Value, and Duration 2 ScrollBar Value! Is it also possible to then play these 2 tones together at the same time?
Private Sub BtnGenerate1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnGenerate1.ClickBeep(Frequency1.Value, Duration1.Value)End Sub
I searched the forum for this and couldn't find anything. Maybe someone can help me on this.I have a child form that has a ToolStripConatiner that holds a ToolStrip, StatusStrip and a PictureBox. I need to have scrollbars when the picturebox is larger than the form. I set autoscrollbars to true on the form but after I added the toolstripcontainer, the scrollbars no longer appear.
The toolstripcontainer is not docked but is anchored to the top,left,bottom and right. I tried unanchoring from the right and bottom, but still no scrollbars.
Does anyone know of a way to make the scrollbars appear, or maybe I am doing this all wrong and can give me a clue.It all works like I want it to except the scrollbars do not appear anymore.
But when I want to use it in the Function, it gives error ("..are not valid within..."). Are there any keyword to make this in the Function or there aren't? [Code]
I generally use to organize codes below lines;#Region "Comments.."#End RegionBut when I want to use it in the Function, it gives error ("..are not valid within...").
Following my test project for making a map editor, I finally got the tile selection part covered.The application can already tell which tile(s) is selected.
So now we will work on "click the map and the tiles will be drawn" part.
When the user clicks the map, I need to "copy" a selected tiles in the tile selector, and "paste" them on the map. The process is a bit longer actually.Or is there a way to directly copy the selected tiles to the map image?
I have a custom-shaped form created by setting the Region to an image. I want to be able to highlight the edge of the form when it has focus. To do this I believe I need to get the outline of the form and convert it to a path so I can draw a two-pixel highlight around the edge of the form.
(1) Is this the correct approach?
(2) If so, how do I get the outline of the region so I can call DrawPath?
i have an image which has 2 colors, black and white.
i wish to get a region object that has all the white areas 'selected'
the shape is not just a polygon, its fairly shapeless
is this the best approach: create a region that is the size of the image and run a loop checking each individual pixel to see if its black, if it is then exclude it from the region. (i've got a feeling this will take very long to load)
