When a panel's AutoScroll is set True then it will add scrollbars for navigation of the entire size of its content. What I want is to be able to set the vertical scrollbar to go to top or zero so its contents top controls will be viewable.

I want to make a panel scroll horotzional with a scrollbar. The panel will have images only (Maybe a label under each picturebox), and I don't have enough space for all the images, so I want to make it scroll horotzional.

So with the stock Textbox, I set the Scrollbars property to Vertical. This is great if the text in my box never changes; I can scroll up and down while the box sits still. If I'm running a background operation that logs output to the box though, the scrollbar resets itself to the top every time I append text to the box.
I know I can set the Textbox.Selection property (or use the Select method) to reposition the carat in the textbox, make note of that position in a variable, then append text, reset the carat, and use the ScrollToCarat method to reposition the scrollbar where it belongs. That's a really (ridiculously) long way around. Anybody know if there's another/better way of holding the scrollbar position, short of actually building a custom control (or using a Textbox and a separate Scrollbar)? It never hurts to try. In a worst case scenario, you'll learn from it.
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.

My problem is that I built this program for my VB class, but I built it on my desktop at home which is a 23" monitor. When this is opened on a smaller screen, you dont get to see all of the project. I want to add a vertical scroll bar but that is beyond what I have been taught and beyond what my book teaches...
how to get a vertical scroll bar to scroll the whole form?
I have a TOS agreement that i would like my user to have to view ...
basically the same way "World Of Warcraft" does it ...
You must scroll to the bottom for the accept button to be enabled and clickable...
but in vb.net i cant seem to find a way to determine the vertical scrollbar postition .
The scroll bars actually move now, They just move the wrong thing. When I click the Horizontal bar it moves the picture box to the left part of the screen and I can scroll the box back and forth. If I click the Vertical Bar it goes up to the top and I can move it up and down. So if I click both of them, the picture box goes to (0,0) of the form. It wont move the image inside. I can't figure out how to assign the scrollbars to the image instead of the picturebox.
Try making a form with a Picturebox, Vertical Scrollbar and Horizontal Scrollbar in it and rename all your stuff the way I got mine:
Horizontal Scrollbar = hsbPicMap
Vertical Scrollbar = vsbPicMap
Picturebox = picMap
Set the image property in the properties box to whatever you want. Try to make the picturebox of fairly big size. Mine is set to 656, 528 in pixels, and the location is 152, 72 on the form. The image I am using is about 1500, 1200. The bars are on the right side and the bottom of the picturebox.
Code:
Public Class frmMap
Inherits System.Windows.Forms.Form
Private Sub HSBpicMap_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles hsbPicMap.Scroll
picMap.Left = -hsbPicMap.Value

View 2 RepliesI have a TextBox control with a lot of text which has a vertical scrollbar, and every time I hide/show the control the position of the scrollbar stays the same.

View 1 RepliesI faced a problem that the vertical scrollbar of datagridview will be un-functional.Here are the steps to rebuild the problem:
1. Add a new datagridview component.
2. Add a new timer to set the datasource of datagridview at a regular time. For example, I add following code on the Timer1.Tick event:
Dim v_connDB As New Odbc.OdbcConnection
Dim v_daCA2 As New Odbc.OdbcDataAdapter
Dim v_dsCA2 As New Data.DataSet
[code]....
3. Then I press the down arraw key on the vertical scrollbar with mouse while the datagridview re-bind its datasource, the vertical scrollbar will be un-functional. And the action will be changed to be re-size the datagridview will I press the vertical scrollbar position.So, is it the bug of datagridview? How can I fix it?

View 1 RepliesI'm having a problem assigning the arrow keys to the right scrolling events.I have a VScrollbar and an HScrollbar. I want the left / right arrow keys to scroll the horizontal bar, and the up / down arrow keys to scroll the vertical bar. The default behaviour seems to be that the first created of the two (VScrollBar or HScrollbar, depending on order of creation) received all arrow key events as a Scroll event. So when I push up / down / left / right, it is my VScrollbar that moves (HScrollbar might move also with the left / right arrow keys, I don't remember). I tried catching the KeyDown event on my form, to manage the left / right / up / down keys myself, but apparently the Scroll events are triggered first...In any case, what would be the "right" way to use a vertical and horizontal scrollbar and have the arrow keys do what they're supposed to do in VB. NET?

I have a load of information on my label in a groupbox on the form there is too much information to be seen in one go so i want to use a vertical scrollbar to move the label up and down inside the groupbox so it can be read.
The issue i'm having is:
1: The label covers the bottom edge of the groupbox (looks a little naff) i need it to fall inside the groupbox if possible.
2: Any movement on the vertical scrollbar seems to send the label in one direction only - so how do i work it so that up moves it up and down moves it down?
Should i use a multiline textbox rather than a label and move the carat?
I need to set the background color of a label based on the value of a vertical scrollbar. i.e, if the user click the vScrollBar the background color of label must change like from 0 to 255.if it reaches to 255 again initialise to 0. I tried color.FromARGB function but it is not working.
View 2 RepliesI have been working on a much larger project and came to a point where I decided threading should be used.It seems in previous version of .Net, a background worker was able to update controls that were were not created on that thread.

This code appears to be updating the listbox.I can see the vertical scrollbar getting smaller, but no data is shown in the listbox. The progressbar is also updating properly while that is working, indicating proper background operation.But what it's not doing is this:
1. Label is not updating percentage
2. The form is not free to be used by the user (me)

View 6 RepliesI've got some server apps that I've been trying to get some metrics from so I can debug them. I found that when scrolling back up the window I'd suddenly get timeouts from the clients. Sure enough, moving the scrollbar stopped the application.
I'm probably missing something fundemental here, but I can't work out why moving the scrollbar on a Console window would block the thread. It's very simple to reproduce:
Sub Main()
Do
Console.WriteLine(Now.ToString("O"))
[code]....
Run that up, and any interaction with the window blocks the thread. In the example below, I just moved the scrollbar a bit and held it in position for a few seconds before releasing [URL]I've tried it with a Timer type loop rather than a Thread.Sleep but the same issue appears. What am I doing wrong (other than not using a service instead!)?
I have a thumbnail control where I am adding Images using openfiledialog and after adding it automatically scrolls down.
So I would like to stop scrolling the scrollbar and just append the Images.
I have tried using this code:
Thumbcontrol1.VerticalScroll.Value=0
It worked fine but the scrollbar is at the bottom and it shows me the first row of Images.
And this is my second attempt by doing this way:
I have just set the autoscroll property to false and it hides the scrollbars and I'm stuck with this so how do I scroll the remaining Images?
And Is there any other method to hide scrollbars and just scroll the Images using mouse? Or any other simpler way to get rid of this?
