Forms :: RichTextBox To Text File?
Apr 25, 2011
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.

Is it possible to append text into a RichTextBox1 where the cursor is? (Ex: In-putting a string from TextBox1 to RTB1 where the user has the typing cursor at.)

i have a simple notepad application where i want a feature of selecting text which is underlined. Usually what happens is when i click a button the app reads a text file and underlines random text in the richtextbox. What i want is on the click of another button to select the text which is underlined. I thought of creating char range, regex all but not getting anywhere. I also dunno how to build a regex.
What i know is since all RTF texts are different we can choose the rtf text instead of simple text to select the underlined text. The rtf of underlined text in my application is this uli0 so manyulnonei where ul and ulnone mark the text as underlined. Now i want to select all such texts which are surrounded by uli0 and ulnonei . I thought of the following method :
1) Create another richtextbox2
2) Paste the text of richtextbox1 as rtf in richtextbox2. I mean show the text in coded rtf (like above) instead of normal rtf.
3) Use simple find to select all the text which is surrounded by ul and ulnone tags
4) process the text.
But this step is very tedious. If anyone could help me in making a simple procedure or build a regex which could process the text surrounded by those tags,

I am trying to add formatted text to a rich text box...
For instance, I want to add a heading as bold ("HEADING: ") and some data after it as regular ("REGULAR Data")...
I'd like to have a couple functions to perform the action.
When I use the below functions to add txt to a single rtf box, I get lines in either all bold or all regular. It doesn't seem to keep the font formatting after it adds text..
Public Function AddRegtxt(ByVal RTC As RichTextBox, ByVal Txt2Send As String)
With RTC
.SelectionStart = Len(.Text)
[Code].....

I would like to know how it's possible to append text between data.
For example:
I have a RTB with "ABC" on the first line and "DEF" on the third line. My question is how would I insert text data into the second line, without changing any existing data.

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

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

I have to save the text boxe values of a form to a text file almost like a data record. I will be saving an Employee First Name, Last Name, Dept Number, and Phone Number. This I know how to do using streamwriter.
next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.

how I can open and read a text file such as this:
Stream Type: MPEG2 Program
Profile: main@main
Frame Size: 720x480
Display Size: 720x480
[code]....
and have the values entered into form controls so I can add/update them in my database.For instance, read the line "Stream Type: MPEG2 Program" and only add "MPEG2 Program" into a textbox or combobox, the line "Frame Size: 720x480" into height and width textboxes and so on.I can read the entire file into a textbox, but I need to separate the values to enter into a database.
