Format Text Read From Line Of Streamreader Input Before Appending To Richtextbox?
Jan 1, 2010
I 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.

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.

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.

The 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.

What I have stored in my file is values related to an account. (Just testing, not going to be used commercially). What I need is to draw the values for the username and password, by going through each new line, but .peek() doesn't seem to work for me.
My block looks as such :
public string CheckAccount(string username, string password) {
StreamReader sr;
string filename = "H:\AccountInfo.txt";
string s;
string result = "";
[Code] .....
My code doesn't read from the 2nd line onwards, it just hangs.

I am currently writing a Login Script, and I am having trouble making StreamReader read a specific line in a text file. This is what I have so far (not the entire script, just the reader lines):
Dim path As String = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
Dim file As String = (path + "LogDat.txt")
Dim sr As New IO.StreamReader(file)
Dim line1 As String = sr.ReadLine(1) '' Supposed to read line 1
Dim line4 As String = sr.ReadLine(4) '' Supposed to read line 4
Dim line9 As String = sr.ReadLine(9) '' Supposed to read line 9

With my datagridview I have column for datetime. I used the following for format.
Mydatagrid1.Columns(3).DefaultCellStyle.Format = "dd/MM/yyyy"
But the problem is it's getting input like MM/dd/yyyy and after pressing enter it's changing to dd/mm/yyyy style. So is it possible to read input like "dd/MM/yyyy".

I have a big issue which I have been struggling with for days now. I have a richtextbox where users Can input text and print it.
My problem is that i don't want to allow more than one page to be printed so i need to prevent the users in inputting more text than what fits to one page.
I have word wrap set to True which means that i really can't count the lines since they are determined by number of return/enter hits. I can't set the character to a max because blank Lines and spaces Can cause this to differ very much.
What i really need i a way to prevent the users in inserting more text than would fit inside the richtextbox frame and the frame may not be resizeble.

I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.
Private Sub btnProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim IndexValues As String()

Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
