How to detect if a scrollbar is at or not at the end of a richtextbox?

I need to detect if a FlowLayoutPanel is showing the vertical scrollbar or not.
View 2 RepliesI have a form with multiple richtextboxes that have synchronized scrolling (ie when one RTB scrolls, the other RTBs scroll down with it). The only problem I have is that I have 10 RTBs, which means 10 scrollbars in total. I would like some of them to not show for simplicity reasons. Basicly the scrollbar of RTB1 to show and hide the rest.

View 1 RepliesI want to be able to have a richtextbox scroll event synced with the scroll of another richtextbox. Do any of you know how this is possible
View 4 RepliesI'm using a RichTextBox and wondered if it's possible to change the height of the horizontal scrollbar. I don't hve much room to fit the RTB so I need to reduce the height of the scrollbar.
View 2 RepliesI am using a RichTextBox control on my form. I want a small code which can detect if any image has been inserted in the rtb or not. (IDE VS 2008)
For e.g. user can just type some text or insert image also (Ctrl + V). Now if we select an image then we can get the type but I want a code which scans contents of rtb and gives me a true if an image is inserted or false if there is none.
I have a class library with a component class in it. Everything is in VB.NET. It's only one file so you can see it here [URL] . On line 92, there is the OnTextChanged Sub. I was thinking about adding ProcessAllLines() (as on line 128) to the end of that Sub, and it worked. However when I was typing in code to the RichTextBox (source which I used is here [URL] after each text change it was checking and processing ALL the lines. So I deleted ProcessAllLines() in the OnTextChanged Sub.I'm thinking about running ProcessAllLines() when the user pastes something to the SyntaksRichTextBox. However I do not know how to do that. I know that it should be something like:
If [CTRL Pressed] And [V Pressed] Then
ProcessAllLines()
End If
I also want it to be in the class library, not the application (Syntaks Demo).

View 2 RepliesSo 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.
I have a richtextbox with a large file inside....I want to be able to search for "Fornication" within the text (KJV Bible) and have every instance of that word to pop up into another richtextbox along with the scripture it is in.

How can I make a textbox have a scrollbar that appears when the text goes off the screen so the user can scroll down as needed?
View 3 RepliesI have inherited support for a program written in VB2008
The problem I have is as follows:
Users have a low screen resolution (company policy) and so can't see the bottom of a particular form.
The bottom of the form has buttons that allow them to navigate between its' four pages so they need to be able to see them. This being the case I need to add a scrollbar to the form.
If I try to drag and drop a vscrollbar from the toolbox it just sits there at runtime (you can slide the button on the toolbar up and down but nothing happens regarding scrolling the page.
All the reading I have done seems to point to forms being given scrollbars in accordance to the AutoScroll, AutoScrollMargin and AutoscrollMinSize properties of the Form itself.
By setting these properties I can get scrollbars to appear in the IDE but they are not there at runtime.
I think I'm probably missing something really obvious here but, so far, have been unable to work out what it is.
So, in my vertical scrollbar, the maximum value is 16. In my application, I made a Label to track the scrollbar's value, just for testing purposes. I noticed that when I move the bar to the bottom, the value is 6. And when a [i]release[/i] the button (stop holding it with the mouse), the value becomes 7. Something similar goes when I move the button to the top: It is 1, and when I release the button, it becomes 0. That's a bit weird, but what mainly bugs me is why I cannot reach value 16?
View 1 RepliesI'm working on a project which must run on several computers, each with their own version of windows.
In Windows XP the project runs fine, but in Windows 7 I get a horizontal aswell a vertical scrollbar. I can't seem to turn it of.
I'm using a MDI parent and several childforms, eacht childform neatly adjusted in size to fit the parent, not exeeding the parent limits.
autoscroll is false
windowstate normal
Am I missing something, or is this just a supurb item in wondows 7?
I am using Visual Basic.Net 2003 and have a DataGrid in the form that I am using but I can't find anuindication or procedure to add a vertical ScrollBar.
View 7 RepliesI create some vscrollbars dynamically and add scroll event handlers to them. I really want to detect when the user has finished scrolling with a mouse up event but this doesn't seem to be part of the scrollbar events.
View 3 RepliesI'm trying to make a user control similar to the Windows Vista/7 breadcrumb bar used in windows explorer. However, when I show the drop down menu for a breadcrumb with many sub items, I get a very long list that sometimes exceeds the screen size. In the Windows Vista/7 example however, there are a maximum of 18 items displayed at a time and a scrollbar appears at the right when the number of sub items exceeds this number (18).

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 .
I have a horizontal scrollbar on my form, and the form is longer (vertically) than the screen. What I'd like is for the horizontal scrollbar to always be visible at the bottom of the screen, no matter where the user is vertically. Right now, the user has to scroll all the way to the bottom of the form in order to see the horizontal scrollbar.

View 1 RepliesI have a game with a large panel in VBE2008 with a Vertical Scroll Bar Control.
The user uses his mouse to move it up and down, etc.
But how can the game program move this control?
For example, the control bar is slid down to the panel and I want my program to slide back to the top starting position when the user clicks on the Reset Button.
I have a bunch of dynamically created scrollbars. They show up as gray against my otherwise colorful UI.
Anyone have code to either set the scrollbar background to a given color or to make it transparent so it paints as the
background color of the panel it resides on?
