Rich Text Box - Program That Will Read From Various Text Files (preferably RTF Files)

Apr 20, 2009

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.

Here is the portion of my code that i am referring to.

Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")

infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()

Catch
MsgBox("Selected Hero currently has no File with us.")
End Try

Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.

{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

[CODE]...

Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.

I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:

OpenFileDialog - to open the file

StreamReader - to read the text files and find the text that I specified

**Not sure on the replace method**

StreamWriter - to write the text from the textbox to the new file

SaveFileDialog - to save the file to the specified location

VS 2010 How To Read From Text Files

Mar 11, 2012

I am making a recipe book that calculates the amounts of each ingredient needed for a dinner.The user inputs the number of people they are cooking for and then my program works out the amounts of ingredients needed, simply by * number of people.I know how to read from text files using commands such as: My.Computer.FileSystem.ReadAllText()But does anyone know how to take text for a text file, then multiply the contents of that file by the number of people?The text file only stores numbers, but I want to multiply each line seperately..Instead if getting the result of 10050*3, I want 100*3 and 50*3 on a seperate line.[code]For this to work, I suggest downloading the full project.You will also need to create a folder with two text files inside it. This will not work without them. "QuantityList.txt" and "IngredientList.txt".

.net - Read And Process A List Of Text Files?

Dec 21, 2010

I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET):

[Code]...

I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file.

.net - Read Multiple Text Files In A Folder?

Mar 20, 2009

I have many text files in a folder. What I can do now is to read through one text at a time and insert it into the database. My little app reads a text file when I debug it. So, I need to run it several times to read all those text files and import them into the database.

My question is how to read multiple text files inside a folder at a time. Here's my code which works fine but it reads only one text files at a time.Private Sub btnRead_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRead.Click

I need a way to loop through a folder and check if there's text file. But I cant get it right. Can anyone show me some code or links ? I'm using VB.NET, .NET 3.5

Fast Method To Read Through Text Files

Jan 18, 2011

Any simple/easy (emphasis on easy, I am a major beginner) to read through text files quickly, search for strings and pull information. I am currently using the 'StreamReader' function and 'InStr' command, but the files I am working with are gigantic and this is taking from 1/2 an hour to a few hours to work its way through.

Here is a sample of the code I am currently using - poke fun at will, I am a major newbie.
strContentsTime1_jntfor=0
Do Until strContentsTime1_jntfor Is Nothing
strContentsTime1_jntfor = objFile1.ReadLine()
'look for string 'time'
strFindStringTime_jntfor = "time"

Forms :: Validate The Text Property Of My Combobox

Apr 20, 2011

I have been searching for an easier way to validate the text property of my combobox.

Below is a background of what I am try to accomplish:

I have a from that contains many controls, mainly comboboxes that are bound to datatables. I have these set up in such a fashion as to when the user begins to type, the values begin to show and auto populate the combobox. This makes the selection process easier to select an actual value in the list. But, as we all know, you can lead a horse to water but you can't make him drink. Users still have the ability to type something that is not in the list. I do not want to allow them to leave the combobox until the have selected or typed a valid value from the list because I am building a SQL query to retrieve data for a later form. I don't want to lose the above mentioned functionality of being able to type it in. I currently have it working as follows, but there must be a more elegant way to do this.

I first populate my combo box like so:

CODE:

The part I don't like the most is that I feel like I should be able to use the list already loaded in the combobox data, but I can't figure out how to do it. So I end up having to reload it, this seem like a waste of time.

Read Text File Into Forms?

Mar 6, 2012

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.

Opening Excel Files - Force It To Read As Text ?

Jun 11, 2010

Application using ado.net

When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.

Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net

For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.

Is there a way to force it to always return all data as text no matter what the actual column contains. ?

VS 2008 OpenFileDialog Control That Will Read A Text File Into Memory - When Select All Files *.* It Does Not Re Appear?

Apr 24, 2012

I am writing an application that will use a OpenFileDialog control that will read a text file into memory and later process it.

I do have the following filter: Text files (*.txt)|*.txt|CSV files (*.csv)|*.csv|Spaced Text files (*.prn)|*.prn|All files (*.*)|*.*"

When I navigate to my test folder that contains a single .txt file, I see that file. When I change the filter to *.cvs that files goes disappears because it has a .txt extension. That is good. But when I select All files *.* it does not re appear? Why and how do I make it appear.
