Cannot Read Special Characters With Streamreader / Streamwriter
Nov 23, 2009To automate mailmerge function in word, i need to join different elements to complete the mailmergedatasource. In one of these file are words with special characters like ©, §,¨, .... When openng these files for reading, streamreader transfoms the characters to unreadable signs. When i give a type to use to open like ASCII, Unicode,it works for one or tho characters but not for all. I have the same problem when the character is read correctly, with streamwriter output to a textfile. Word cannot read the textfile and ask to define which type of coding should be used. In most of the cases not all the characters can be converted to readable characters.

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

Streamreader Limits - The Streamreader Works Fine Until The File Is More Than 100,000 Bytes Long?
Apr 19, 2011I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server.

StreamReader/Writer - Loads An Entire Text File Into A Streamreader Variable
Jul 9, 2009I'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.

View 2 RepliesIf/Then In A Streamreader?
Nov 19, 2010I am doing an assignment for my programming class in which we have a text document full of names (one per line), and we set up a program with a textbox, button, and listbox. The user enters a name in the text box, clicks the button, and it searches the document for the name. If it's found, the listbox should say so and list the line number.I can get that working no problem, but the assignment also requires informing the user if the name can not be found, and I am not doing something right with that.My code is as follows:
Quote:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim inputname As String = TextBox1.Text
Dim linecount As Double = 0
If I remove the three bolded lines and it finds a name, it will work fine to the point that it informs as such and tells what line it is on, but it won't inform the user if a name wasn't found, which I need. I thought adding those three bolded lines would help, but when I have them in there, it will incorrectly display "Name not found. " no matter what name I type in the box, even if it is in the text document.

Search Box In Streamreader
Jun 11, 2011magine there is search box (textbox), and below there are a search button with a rich text box.My text file located in the drive C is like this: [code]I want to search only two types of items in my text file located in drive C, namely: Construction and Non-construction. When the user will type a product name, OR size, OR whatever, he must get results only for the Construction or Non-construction. The user must not get results for the Food. And the user can make misspelling of words in the search, so the Search box must tackle it. And yes, the results should appear on the rich text box on the form itself.What is the code of doing the Search according the criteria above? All I know I have made a srteamreader code but when clicking on the search button, it is giving me all the texts i wrote in the text files. However, I want only some lines to be read.
