I'm working on a new application and I use the SetScrollInfo and GetScrollInfo Api's and I'm having some problems: 1. I'm able to scroll my own textbox control on my form but I can only see the scrollbar being updated and not the text inside the textbox control moving I'm using this
[Code]...
I am using SetScrollInfo to set the position of a scroll bar in a text box...
Basically the call is working as it sets the position of the scroll bar... but the text does not scroll and is still at the last position that the scroll bar was in - when clicking on the scroll bar the text scrolls to the correct location
I'm using Windows 7 and I built a small application that just moves the scrollbar of the current active window to some value.The problem is that nothing happens. I tried using GetScrollInfo too but I only got 0 in the nPos parameter.
This is my declartions and constants:
Private Declare Function GetForegroundWindow Lib "user32" Alias "GetForegroundWindow" () As IntPtr
Private Declare Auto Function SetScrollInfo Lib "user32" (ByVal hWnd As IntPtr, ByVal fnBar As ScrollBarDirection, ByRef lpsi As SCROLLINFO, ByVal bRepaint As Boolean) As Integer
[code]....
On the form load I just do a delay of 2000 milliseconds so I could focus on another window, wait and nothing happens.
System.Threading.Thread.Sleep(2000)
My.Application.DoEvents()
ScrollCurrentWindow()
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.

I 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?

View 2 RepliesI want to make it so when I scroll down on one listbox view, it will do the same on the other one. How do I do that? I have one listbox that lists usernames, and the other one that does the message... so we don't have to worry about one having a longer height than the other one.
View 7 RepliesA long time ago I wrote a program in VB6 that performs sideways scrolling by:creating a couple of device-independent bitmaps twice as wide as my display window.plotting my streaming data on the first bitmap until it reached the right edge of the window.copying the bitmap to the display window at the refresh rate.copying the data to both bitmaps, the second bitmap starting at x = 0 when the first reached x = windowWidth
ping-ponging the two bitmaps as the data continued to arrive The result is a display that scrolls sideways continuously as long as the data stream is flowing VB.NET and Windows.Drawing hardly support any of the VB6 tools I used to do this, and I can't find anything in the documentation that can take their place.

View 2 RepliesI have a textbox to which text is continuously appended (every second new status data at the end).I would like to act it as follows:- When the cursor is positioned at the end: Stay at the end, scroll the textbox (text disappearing at the top).- When the cursor is positioned somewhere else (not at the end): Stay exactly there, don't move the cursor, don't scroll, don't change the top line of the textbox.This seems to be surprisingly difficult (tried quite several ways).This is how far i came:

I have a read only multiline text box I'm using as an output box for a continuous string of data, when my data gets to the end of the last visible line the scroll bar activates and my text vanishes past the bottom edge of the text box and I have to manually scroll the text box to get back to the end of my data. is there anything I can do to make the text box scroll up so I always see the end of the data stream being past to it?
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox2.Text = TextBox2.Text & TextBox1.Text
End Sub
End Class
Above is a really quick and dirty bit, take input from one textbox and output to the other using a button click or some such. After so many button clicks get the text box to scroll without doing it manually with a scroll bar, so you always see the latest entry.

I'm looking for an example in VB.NET of a continuously scrolling form. This would be similar to a continuous form in Access but with a major difference in that when you scroll it the whole thing moves up or down instead of the data jumping up or down to the next section. If you are not familiar with Acces, this would be a form that lists data down the form in sections, one per record, in other words, like a bunch of forms strung one after the other. When you scroll down, the record at the top gradually disappears and is replaced with a new one at the bottom.
This needs to be a form with controls, not a datagridview.Right now, I'm trying to find an example of this. I tried searching for one and couldn't find one. Does anyone know of an example of a continuoulsy scrolling multi-record form where the whole form moves in VB.NET?
I have a DataGridView with, say, a half dozen columns on it; the right-most column being the widest (a description that might exceed the window's width). If the user presses the Home/End or PgUp/PgDn keys to navigate thru the data, it will sometimes scroll horizontally to the right, which is annoying. Is there a way to prevent this?
I've tried .ScrollBars = ScrollBars.Vertical(so there's no horiz scrollbar), but that doesn't solve the problem. I'm not sure how to make the 1st column be always visible - but even if I make it visible upon displaying the grid.I guess basically I don't WANT it to scroll horizontally, except when the USER scrolls.

I have this timer system set up so that every 2 seconds a new line of code is added to my RichTextBox. The problem is, when the box fills up the scrollbar doesn't automatically go down. Every time a new line is added by the program, the user has to scroll down manually to see it. I would think there would be a simple solution to this, but I'm a VB n00b,
