VS 2010 - Closing A Text File Loaded Into A Richtextbox?
May 30, 2010
I have no problem loading the contents of a text file into a richtextbox(rtb) with the below code. I can then edit and save the contents of the rtb to the file, and clear the rtb.
However, is the file still open? Does loading a text file into the rtb actually open that file? I am asking because I can't find any methods or techniques to close a file that has been loaded into a rtb. Is clearing the rtb the correct procedure?
Public Class Form1
Dim openFile1 As New OpenFileDialog()
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
[code].....

I have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?
Here is my code --
Imports mshtml
Imports System.Text
Imports System.Net
[Code].....

I have a small application (in VB.NET 2008) which gives the user the option to open a PDF document. This document is stored on a mapped network drive and is loaded in to the AxAcroPDF Control.
When closing my application I get the following message
The instruction at "0x0700609c" referenced memory at "0x00000014". The memory could not be read.
I've been google-ing this error message, but seen only a lot of problems, but no solutions.
I also tried using the WebBrowser Control, but this gives the same error.

I have my datagridview being loaded from a Text File and then being saved to a text file as a comma separated file - the commas obviously separate the columns. However in some of the cells prior to saving, I have data that i have inputted over two lines by pressing shift + return.
E.g.
"SOLD
10/05/2012"
This saves fine, but obviously shows up in the text file as a line break, which then causes some issues when I choose to re open the info back into DGV. How I can code so that it saves as a line break within a cell, rather than a completely new line.

I've decided to come back to working on an old program of mine, and it's been coming along nicely, but there's this one thing that I can't get working.I have formatting options (Bold, Underline, Italics, Strikethrough) available on my program, and they all work properly. I'm giving users the ability to export all of their text from a single page on the program to a .rtf file. However, the problem I'm experiencing is that each page has numerous RichTextBoxes on it, so I cannot simply use a RichTextBox1.SaveFile() command or something similar. I want to compile all of the text (including formatting) from all of the RichTextBoxes and put it on a single .rtf file. Currently, I'm getting the text from the RichTextBoxes using the RichTextBox1.Text command; unfortunately, that only gives me plain text without formatting. So, what I'm wondering is: how can I get the formatted text from a RichTextBox? Is there any command?

I have a My.Settings file that has a folder path that the user will select.I need to export text from a RichTextBox to a file, however, I can't seem to figure out how to use My.Settings as the path where the text file will be created.
Right now, I have:
Me.txtlog.SaveFile("C:UsersmycomputerDesktopNew folderfounditems.txt", RichTextBoxStreamType.PlainText)
which works fine, however, the My.Settings.destfolder is "C:UsersmycomputerDesktop estfolder"
I have tried:
Me.txtlog.SaveFile(My.Settings.DestinationFolder, RichTextBoxStreamType.PlainText)
but it doesn't work - and also I do not know how to name the text file from the above code.

With the intention of creating a program to interface with a serial port device, I recently started learning vb.net. To keep the structure neat the vb code has been split into two places; the first is the code behind for initialising, clicking buttons etc., whilst the second is for managing the comm port. Respectively, these are named 'MainWindow.xaml.vb' and 'ComPortManager.vb'.
In 'comPortManager.vb':
Dim RXArray(2047) As Char ' Array to hold received characters
Dim RXCnt As Integer ' Received character count
