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,

I'm trying to do two things. I have a Richtextbox which i'm continously adding text to from a standard text box. I want that new text to appear at the beginning of the existing text, not at the end of the existing text.I've got the following code but it's not working. The new text keeps going to the end of the existing text.
Dim newtext As String
newtext = TextBox1.Text
RichTextBox1.AppendText(newtext)

I am new to programming- basically I have a richtextbox1 with some data from the database,but when you scroll it scrolls 3 lines, whereas I want to scroll only one line at a time.

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 am writing an array in a file with this loop.
sw.WriteLine("attributes")
For i = 0 To noatts - 1
sw.WriteLine(attName(i))
Next
This is creating weird results though.

Anyone know why could that be? In other parts of the file writeline works well. It only creates extra lines on that specific section. Btw: the file looks good if viewing by notepad, the extra lines appear when viewing in wordpad. Apparently that matters because when I reuse that file to read some values in my program, it crashes cause it reads those empty lines instead of the attributes.

View 2 RepliesThe sample below does what I want it to do and that is once I've filled the maskedtextbox and press enter it goes and does stuff. However, because the maskedtextbox is full I get an annoying 'beep'. So I figured I'd just use the tab key, I changed theChrW(Keys.Return) to ChrW(Keys.Tab) but it doesn't fall through, it just changes focus to the next maskedtextbox that I have. Is there a way to lose the beep? Or how do I get the tab key to fall through?

So i wrote a script which does a few things and richtextbox2 is updated as follows:
a = 27,130,000,000
b = 2,930,000,000
c = 4,290,000,000
Problem is, when i copy the contents of richtextbox2 to the clipboard using "clipboard.settext(richtextbox2.text)" and then open up note page, and paste the clipboard contents, it is wrapped wrongly and i get the following in note pad:"a = 27,130,000,000 b = 2,930,000,000 c = 4,290,000,000"
I am using "system.envoronment.newline" in my code to start a new line.
When I am editing VB code inside a .aspx file in Visual Studio 2010, my code is automatically indented in a bizarre way. I have searched through the options and can't find anything that fixes this. [I thought unchecking Pretty listing (reformatting) of code in Text Editor -> Basic -> VB Specific would for sure do the trick but it didn't]Example -- here is the beginning of a .aspx page:
<%@ Page EnableSessionState="True" Language="VB" Strict="true" %>
<script language="VB" runat="Server">
Dim foo As String
If I go to the end of the "Dim foo" line and hit it will indent. If I fix the indentation, the next line will do the same thing.
I am using Visual Basic 2008. However, the Report a Bug function does not work, which in itself is a major bug.While I am typing in the code editor, these annoying popups keep popping up and completely blocking my view of the code. I have no idea what these popups are showing and do not need them. I have not been able to find any way of turning them off. I consider this another major bug.

View 1 RepliesFor some background please see the following thread where I just posted a solution that worked for me:[URL]..The issue involves the shifting of controls on a form when it is first being loaded (it may not necessarily happen in the Load event though). As I write in the first linked thread above.I have noticed it on a few projects -- all MDI -- but with no apparent rhyme or reason as to which controls get "afflicted". I've had it happen on labels, textboxes, pictureboxes, radio buttons, etc. Also the distance they shift is varied, as well as teh direction the move - sometimes different directions on the same form.There are no consistent properties that these controls share and I am positive that it is not a simple anchor issue. This is a true and serious bug and amazingly frustrating because there appeas to be nothing you can do or test to hack into the behavior and begin to debug it. Scrapping a solution and redoing it from scratch can seem like a viable answer it is this vexing.
My solution was to set the AutoScaleMode to None and the issue resolved itself immediately. Since many people come to this forum with Forms questions I thought it might be useful information -- at the very least it might get on the radar of some of teh answerers here in case a question pops up of this nature in the future.

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?

A 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.

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.
