I am trying to read a txt file into a richtextbox and been doing some research and from what I read this should work, but I get a error saying that the file format is not valid. I thought that the richtextbox control can read txt files as well as rtf files automatically. The file I am trying to read is saved in Notepad as a txt file. I can open the file if it is rtf, but not if it is a txt. Any Ideas why it wouldn't work? I am also attaching the textfile I am trying to use. Here is what I got so far.
I am not sure if this is a dumb question or not? Is there a way that we can read a .docx file and put it into a richtextbox? If so how? I have tried.LoadFile and it throws an exception saying invalid format? I tried reading the file from a stream and that also doesn't work?
I use a richtextbox control on a windows form for users enter formatted text into it and store it in an oracle table clob field. I use clob because data can be longer than a varchar2 field could store. There is no problem when I write it down to database (I write its rtf value using bind variables and OracleClient.OracleParameter) but when I want to read it back to the richtextbox there is nothing in the richtextbox control.
I checked database turns the data as I wrote it down. But the control displays nothing.
I found a strange issue with the combination of RichTextBox and RegEx.If I load a text file into a RichTextBox and use
Dim matches As MatchCollection = Regex.Matches(RichTextBox1.Text, "^H(.+ ){10} ", RegexOptions.Multiline Or RegexOptions.IgnoreCase)
then the RegEx will run blazing fast.OTOH if I load the text from a file straight into a string and feed this string with RegEx.Matches using
Dim FullText As String = New StreamReader("c:TempTextFile.txt", System.Text.Encoding.UTF8, True).ReadToEnd Dim matches As MatchCollection = Regex.Matches(FullText, "^H(.+ ){10} ", RegexOptions.Multiline Or RegexOptions.IgnoreCase)
then the regex will run for ages.Now obviously the RichTextBox does something to the text. I found that loading the text into the RichTextBox will eliminate the first 4 bytes of the text (is that the byte order mark?). However, trimming those 4 characters with SubString won't solve the problem. RichTextBox does some other processing that I'm unaware of.I'm using RegEx both on client and server side (client can load text files into a RichTextBox to test and setup various RegEx's and the server will process text files according to these previously setup RegEx's). Needless to say that a regex will run blazing fast on the text file loaded into a RichTextBox, while the very same RegEx ran through the very same text file will seem to lock up the server side service.My question: what kind of text processing does the RichTextBox do and how can I mimic the behavior in a server-side process?
I have a txt file that I need to read into a listview, but I need to read from a specific line in that file. Below is a sample of the txt file to read,
I need to display my text which were read from .xml database as color, italic, bold, etc. in richtextbox, how do i make a code to do that,The reading and displaying is fine, but when certain word like again is read it should display in italic, and whenever a word like over is read it should be display in bold or underline etc.I use vb.net 2003 and .xml for the database.
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.
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.
I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.
Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.
I'm using VB.net to open the files. More specifically
Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
# TAG NAME = is saved to a file using the code below but when I load that same file back into a RichTextbox Control using additional code below, I get inconsistent results as I try to parse the text. Has anyone else had this problem?'Save the contents of the RichTextBox into the file.richTextBox.SaveFile(saveFile1.FileName, RichTextBoxStreamType.RichText);'Retrieve contents of File into RichTextBox control Dim logData As String logData = System.IO.File.ReadAllText(path + "\" + filenname);
I'm trying to make a program that can read .mp3 data (Such as Artist, Album, Year, Track number, etc), but I need to be able to do two things that I have no clue how to do:
1. Read starting from a specified string (E.G, On one line it states: [code]
2. Read until a specified string (E.G, On the previously stated line,I need to read starting from what I said, up until.
i need to read binary file and in this file found the string and replace it with other one and save the file afterwords. I found many example to read binary, but to find and replace is for me mistery.
I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know: 1. how to open a new file 2. how to specify the record length 3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
I have a fairly simple XML file that I just want to read the data from.
It has 3 levels, root, main section and items. There are no attributes. I want to go to the first main section by name, then read in all the items. The items all are named the same. I've seen this done before, so it should be ok. No writing will be done. Basically this is a static data file
I am using the following code and I get an error that the file isn't residing where in REALITY IT IS! I know its my syntax.BTW, this directory structure I also created in the Solution Manager.
Im new to the forum so don't blame me if I posted this in wrong catagory :P , this forum helped me out plenty of times so I tought let me ask for help with a big problem. Ok this is the matter:I am working in visual basic 2008 on a program that should search thro a log file (what logs a chat) for specific words , than warn me if some one said that and display his name seperated in a textbox.What have I done is, that I made the code to open the .txt log file in a RichTextBox , I got a timer that checks every few if richtextbox1.text.contains(TextBox1.Text) so if it contains the words what I am searching and if the statement is true than it does beep(). K that is quite simple , for now the problem is to take the poster's name out of that log file! Here is how such a log file looks like:
I have a richtextbox with a large file inside....I want to be able to search for "Fornication" within the text (KJV Bible) and have every instance of that word to pop up into another richtextbox along with the scripture it is in.
it seems so simple but i cannot find the answer. I have a menu strip item (open...). and I have a RichTextBox1. I need to open *.txt and have it displayed in RichTextBox1. Currently I have no code behind 'open...'
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.
