View 8 RepliesVS 2008 Determine If User Has Scrolled To The Bottom Of A Control?
Aug 22, 2010I am modifying some code I found here to test to see if a user has scrolled to the end of the control. In this case the control is a Crystal Viewer but I posted here because I think the issue is based on the vertical scrollbar not the Crystal Viewer itself.
The code flags an error at
Me.CRViewer.Controls.OfType
Indicating 'OfType' is not a member of 'System.Windows.Forms.Control.ControlCollection'.
I understand the concept that I can't reference something that it is not but I don't know how to fix it. The original code was for a DataGridView.
The ultimate goal (not finished) is to find out when the user has used the mouse or possibly the scroll bar itself and if it hits the bottom of the page of the viewer, then trigger a new page so it looks like they can just keep using the mouse to scroll.
Public Sub New()
Me.InitializeComponent()
Dim vscroll As VScrollBar = Me.CRViewer.Controls.OfType(Of VScrollBar)

[2008] Keep To The Bottom Of A Rich Text Box And Read Changes In Txtfile
Mar 16, 20091) On one of my forms i have a richtextbox but whenever the programs ads something like richtextbox1.text = richtextbox1.text & "New Entry" The box goes back up to the top and you need to re-scroll down to the bottum. Is there anyway i can have it to always go to the bottum when something is changed instead of reverting back to the top. Because things are added almost every 1-2seconds until it gets to the point where you cant scroll down to read what was said before something new is added and it jumps back to the top.
If you dont know what i mean make a timer of 1 second that ads somethign to the textbox and youll see what im talking about.
2)Or better still is there anyway to get the program to recive new lines from the textbox. Basicly I have a textfile which is read by around 4-8 clients. I want each client to know what its read so it can process the textfile but i dont want it to say add something like ' to the start of every line its read and ignore all ' lines because then the other client will ignore it to. So what im looking for is a sub that will process the textfile and put any previous unread lines (previous unread lines that session [i.e since program restarted]) into a string array like newline(1)

View 8 RepliesVS 2008 - Simple Text -> Xml Program - Save The Contents Of The Bottom Text Window To An Xml File
Dec 23, 2009I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
