View 9 RepliesI have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
I'm having issues getting a text box to scroll to the bottom Every time text is entered into it. I searched google, and came to a bunch of solutions, some of them on this forum, but I can't seem to get them to work. One of them was a sub..[code]the problem is I don't know where to declare the sub. I've tried in form1 load, my click button click event but nothing worked..when ever I put the sub code in my source it seems to cut off the rest of my code, and generates a bunch of errors..
View 4 Replies1.I want the text to scroll down in the textbox.
Well, if I use AppendText() it does something like this, but if you scroll up, then each time you receive a message you will be scrolled all the way down.
Is there a way to make it scroll all the way down if I am scrolled at the bottom? Meaning, it would check the textbox where its scrolled at, then it would if scrolled to the bottom, and the text and scroll down, otherwise, it would just add the text.
2.Is there a way to make the mouse scroller scroll the textbox? currently it onlt does so when the textbox is the active control on the form, but can I make it always scroll it when the mouse is placed over the control, like it seems to do in MSN when you have a chat open for someone and you are typing a message, you can scroll at the same time without moving focus to the top part where the text is displayed.
I have a tab control with two tab pages. One page has the auto scroll enabled since there is to much content in the page. The middle mouse wheel doesn't scroll the scroll bar; I have to actually click and hold the scroll bar and drag it down to scroll. Is there a property to allow this?
View 2 RepliesI am having an odd problem with the Horizontal Scroll Control in my program.I am using it to scroll a series of panels across a form.This is my code:
Private
Sub scrHoriz_Scroll(ByVal
sender As[code]....
The problem is that this works perfectly if I use the left and right arrows and it also works perfectly if I use the scroll bar's slider SLOWLY. If I scroll using the slider and move it quickly then the scroll gets out of sync.The small change and large change are both set to 1 and maximum is set to 8
I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.
View 1 RepliesI am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.
View 4 RepliesDuring my program I put lines out to a text box on the screen as a form of logs.After each line is added I do a ScrollToCaret() to move to the end of the lines.However, if I'm manually scrolling around the logs/lines (eg: using the scroll bar) I don't want to that.
Is there something I can check so as not it issue the ScrollToCaret() if the user if currently scrolling around in the text box?
My rich text box overflows with output during execution, thus activating a vertical scroll bar. When the program ends the created text box information disappears.I have tried a message box prior to exiting the program to stop execution but then nothing responds until the message box is A instruction doesn�t accomplish my goal either. I see nothing in the text box properties window which looks like it would do the trick and no luck with Googling for info so far.

View 11 RepliesHow would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.
View 4 RepliesI have a textbox that shows events on a program, which I add. I use the 'scroll bar' option on the textbox to show the vertical scroll bar, but how do I make it stay at the bottom most possible? I am using this code while I am trying to learn how to do what I want the scroll bar to:[code]But how do I get it so the scroll bar will stay at the bottom-most it can? I'd like the newest, most recent events to appear at the bottom of the textbox, and to have the user not have to scroll down every time something new is added.
View 2 RepliesI am using VB .NET. I want to know how to make the scroll-up and down arrows visible for my text boxes if the user wishes to enter more lines of text than the size of the text box can take. I would like the user to be able to scroll up and down after he/she has entered all the text.
How do I activate this property - should I be using some other control other than a text box for this?
I want to search the text in my multiline textbox with a vertical scrollbar:
mEvent.Focus()
mEvent.SelectionStart = InStr(mEvent.Text, FindString.Text) - 1
mEvent.SelectionLength = Len(FindString.Text)
This works fine, but if the found text is too far down, I have to manually scroll down to see it. How can I automatically scroll down so that the found text is visible in the text box?
I have a simple Sub:
[code]...
It's job is to scroll the textbox (txt_folderactivity) after I update the text box with a new entry. The textbox is multi-line, so this keeps us at the bottom so we can see the new stuff. This sub gets called whenever any of the other subs add a line for things like file rename, deletion, etc. based on file system events (using Public watchFolder as FileSystemWatcher).I had a crossthread issue with just updating the textbox, but I wrote in a Delegate /Invoke for that and it works fine (something I found online earlier this morning), but now I have another issue and I'm not sure how to work it.
I'm getting a crossthread issue with this specific Sub specifically at the SelectionLength, and I'd like to set it up with a Delegate and Invoke and such, but I don't know how specifically. I've searched and read, but I don't get it. Do I need a seperate invoke on each of the 3 lines, or is there an overarching Invoke for the whole bit I'm still new-ish to VB and I don't know how to proceed. I've read some MSDN pages and stuff, but they aren't explaining what the problems is really and what I need to do (or prehaps I'm just not getting it).
Textbox scroll bar is enabled but after full page of text the scroll bar comes up, new text cannot be displayed unless scroll bar is dragged down. Is there any way that I can set to move scroll bar automatically so new text always comes up?

I'm having a problem where I have elements such as Listboxes and Rich Text boxes that I want to set to size automatically in xaml according to the size of the window, but I only want it to resize to the size of the window and then put scrollbars if the content is any bigger than that.
Unfortunately, the only way I can get scroll bars to work is if I set a specific height of the listbox/rich text box (which does not work because I want it to automatically resize to the height of the grid that it is contained within, which is generally the height of the window (auto).

View 2 RepliesI am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.

View 1 RepliesI recently just finished an IM application but there's one really annoying bug. The problem is that every time a user enters text the scroll bar goes up towards the top, making the user have to manually scroll down to see a new message. I've looked into the properties window and couldn't find anything, so I'm hoping someone here might have some kind of fix for this:) I can change between Textbox and Richtextboxs if it needs to be done
