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'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.
View 6 RepliesI am reading text from a file (*.TXT) 1 line at a time using streamreader. As I read that input, I am looking for specific starting and ending character strings ("<" and ">") . When I find those strings, I would like to select the characters between those string and have it set to BOLD and BLUE before appending that input line to the contents of a richtextbox.The only way I have found to do this is to first append the input line to the richtextbox then use the richtextbox.selection (color and font) methods to change the text.

1. i got 1 label and 3 textboxes. in textbox1 the value is 02. t2 is 20 and t3 is 43. how do i do to make it post like this in label1? 02:20:43 i was using this

but that didnt work at all. and removing the "" didnt help.
2. and the second question is almost as same. how do i do to make the 02:20:43 apear in a textbox in form1 if 02:20:43 is written in form2?
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.)

View 6 Repliesi 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)

View 1 RepliesHow would I go about appending text to a Textbox without losing the current scrollbar position? I thought somehting as simple as:
Textbox1.Text += "MyString" & vbCrLf
would work, but it just sends the scrollbars to the top.
This append feature does not seem to work. I've looked in many places to no avail. The other examples below for writing and reading seem to be going fine.
Private Sub ApFile(ByVal textFilePath As String)
Dim objWriter As System.IO.StreamWriter = file.appendtext("textTBD")
objWriter.WriteLine("textTBD")

Lets assume I have a DataSet that contains the following info (columns seperated with | character):
1 | Logan | Young
2 | John | Doe
3 | Jane | Doe
4 | Joe | Soap
If I now write this info to a text file, but later want to append 5 | Susan | Sarandonto the end of the text file, I obviously want to check that the text file doesn't already contain the data that I want to append to it. I'm having a little difficulty figuring out how to perform this check...I know you'd have to loop through every row in the DataSet's table and compare it to every line in the text file. That part's easy.
We are trying to Open a text file and if our needed information isn't in there, we need to write it, otherwise we need to append to the existing text. We had it working in VB6 (below) and i havent the slightest clue

I have a VB 2008 program which shows the user's results in a ListView, and permanently stores them in a Notepad (.txt) file. The program works fine when I run it using Debug. The permanent records show up on a .txt file in the "bin". However, I want to publish the program as an executable file. I have tried this using my normal method of selecting "Publish" from the "Build" menu, and my program runs fine but there is no .txt file to be found.
View 3 RepliesThe user starts out by pasting text into a textbox:
1.Phototypesetting was superior to automated typesetting because it was
(A)Easier
(B)Faster
(C)More flexible
*(D)All of the above
What I want to do is to tag the sentence and format it as follows: MC Phototypesetting was superior to automated typesetting because it was (A)Easier incorrect (B)Faster incorrect (C)More flexible incorrect (D)All of the above correct Using the following code I can easily replace the number (1) with MC:
TextBox1.Text = Replace(TextBox1.Text, ("1."), "MC ")
But for the life of me I cannot figure out how to tag each choice with correct or incorrect. The correct tag will go to the end of the choice which starts with * eg *(D) All of the above correct, while incorrect should go at the end of all other choices.
Stuff like this makes me hate computers! Anyways, I'm again struggling with something relatively simple - or so i thought.I have a sub:
[Code]...
Then, I have a sub that runs every minute, calling yet another sub, which calls this one. Before you say whoa! that's too many, I'll say that each of these subs has a different purpose.The whole problem is that the WriteToFile sub writes only once to a file! Instead of continously writing to the file every minute, it stops at the first line.
I have a piece of software that can be used either on an admin account or a standard user account of a completely stand-alone, Windows XP machine.
I have also set up some log files that the system uses when it either performs an admin function or if an error occurs. the location of these files is a C: location - not (from what I can see) associated with the admin account in any way.
When running the software from the admin machine, the log file is appending fine. When running the software from the standard user machine, the log file causes an error, suggesting that "Access to the path 'C:HNP MTWP Log FilesAdministrative ToolsAdmin.log' is denied.
This error occurs when first setting up the FileStream. Here is my code.
Imports System.IO
Public Class Log
Private Const cnDirectory as String = "C:HNP MTWP Log FilesAdministrative Tools"

How would I use the BinaryWriter to append binary data to a file that is very large? Say a file that is 3GB in size. The BinaryWriter's write method will only accept an integer for the index value. I've attached a screen shot of what I'm talking about. If I were to enter a value that exceeds the size of an integer on my 32bit Windows XP system, which I believe is 2147483647 it will reject it right?
