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.
Is there a comprehensive guide to programming graphics outside the normal get-a-picture-from-here-and-put-it-there model?
how to print sideways? I am trying to create and print two identical receipts horizontally on a std 8 1/2" X 11" sheet of paper in VB2005. I am sure there is probably the 'correct' search term somewhere in the archives but 'print horizontal', 'print side-by-side', and 'print sideways' just doesn't seem to catch the assistance that I am looking for?
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 mouseDownPoint; Point mouseUpPoint; Point mouseDragPoint;[code]......
I currently have a label scrolling text, But for some reason it only displays Certain song titles/text. Does Anyone know why?!

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?
i need to scroll a datagridview, my scroll bar is set to false so i need to do it using code.currently i am scrolling using the following code, but i would like to modify the code to scroll from one line to the next and see the blue bar actually selecting the rows. how do i do so
Private Sub grdMouseWheel(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
I 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.
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
I want a code that when applied to text in Visual Basic 2008 it scrolls across the screen. I don't want anything flashy, just something basic to start off with.
I 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:
Private Sub addToTextBox(ByVal daStrg As String) Dim posAtEnd As Boolean, selPos As Long, selLng As Long If myTextBoxForm.txBox.SelectionStart = myTextBoxForm.txBox.TextLength Then
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.
Is it possible to create something like the iphone scrolling on a windows, you could also say how google Maps scrolls. If so how would you think you would go about it?
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.
I'm making a Shooter game like "1943" and "Jamestown". I was wondering how I would make the scrolling background to simulate moving forward and How would I make this efficient? I was thinking about using a animated GIF or to make a looping BitMap.
I have some data in my DataGridView. I want the user to be able to scroll through data but not select any item. If I make enabled=false, even scrolling does not work
1: the blinking carat from Form5.Textbox1 is showing up and scrolling along with my text in Form1.Label6 I want to remove the carat as it looks messy! how do I do this?2: Form1.Label6 starts scrolling across the bottom of the form at the speed I want. But then slows down once the last letter has come into view on the right hand side of the form? I have changed some of the settings and got it to be the same all the way across with the timer set at an interval of 50 and the following
scrolling text Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
I am having some trouble getting my menu bar to not scroll down my application when I scroll down. Is there a way I can I guess dock it to the top where the close button and the maximize/minimize button is so that when I scroll down you can still see and get to it instead of having to scroll back tot he top of the application?
I have the following Code in my Form, but the PrintPreviewDialog is not showing all rows. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
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 have a picture box control on a form that displays an image that I draw. I create a bitmap (oBM) using the picture box's ClientSize width and height. Then I create a graphics object to draw on... OutputDevice = Graphics.FromImage(oBM)
My 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.
I am currently working on a web browser using visual basic and i think i am stuck at this point where i have a panel and i need to scroll it when mouse hovers a button .. actually if i can find how to scroll the panel without using the scroll bar , i think i can modify it for using it with mouse hover.
I am creating an user interface for a touch screen in visual basic. The application displays files in the web browser control. But unfortunately the touch screen accepts every touch as double click. Hence the user can not use the scroll bar for scrolling. Is there any way to make scrolling a button event?
