Getting Rid Of Characters In Text From Txt File
Nov 29, 2010
I have a string of text i captured within AutoCAD (0.000000, 0.000000, 0.000000) wich is saved to a text based file named position.txt.as you probably have gatherd with a file name such as position.txt the text could be composed of any random number combination eg: (5.745379, 0.846290, 150.6459046).However for it to be of any use to me I need the captured string to exist without spaces or brackets how can i achiev this in VB.net?

what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

I need to delete some characters in a line from a text file.
How can do this using forms?
for example I have
1.pencil hbewe wqeqwe
2.pencil 2bq
wqweqeqw
3.eraser eqweqw eqweqw
I want to keep only the
1. pencil
2.pencil
3.eraser
in the file. How to do that?

I would like to read a text file into an array of strings using System.IO.File.ReadAllLines. However, ReadAllLines strips out some odd characters in the file that I would like to keep, such as chr(187). I've tried some different encoding options, but that doesn't help and I don't see an option for "no encoding."
I can use FileOpen and LineInput to read the file without modification, but this is quite a bit slower. Using FileSystemObject also works properly, but I would rather not use that.
What is the best way to read a text file into an array of strings without modification in .net?

I have a text document that contains a bunch of data sets. However before each data set there is a number surrounded by brackets. I need to go instance by instance of brackets and pull the number between the brackets and the lines after the brackets until the next bracket. Here is an example of the text file that contains the data. I know how to read from a text document, do substring, do contain function, etc... I just am extremely stumped on how to do this. Here is an example of a couple entries of the text document...
[4188]
LongName=
ShortName=
LauncherDirKey=
[Code]....
Notice how different sections have a different amount of lines therefore a reading a fixed number of lines is not an option.

I am reading a text file with mostly alpha characters. the content is not really relevant but the size of each line is very important. The process I will feed this text to will require each line be no more than 50 characters. So I will pre-process the text and add line feeds to make sure that happens.I tried several VB.NET regex like ^.*$ but that doesn't really break up the lines by 50 characters. I would take the result and iterate through each match and then cut it up and write it to an object in memory. Can this be done with a single regex pass?Otherwise I will use a streamreader and on each line check the length and if <=50 write it out with a streamwriter. if >50 cut it up in sections of 50 and then use streamwriter.
A brief example of my text:
119 SMITH KATY AAAA F ZZZ X NB SX ET
MILES,200/LM450

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

I'm using IO.File.ReadAllLines(FileName) to read all lines from text file to array of strings at once. Problem is, text lines include ANSI characters above ASCII value 127 (Scandinavian letters e.g. "Ä" (Ascii 196), "ö" (Ascii 246) and "é" (Ascii 233). Array is build up nicely, but all chars above ascii value 127 are not shown right. How can I use ANSI character set with .ReadAllLines to correct this problem? In VB6 with "Open Filename For Input As #1 / Line Input #1, txtLine" there wasn't any problem.

I can search for the word Love in an .rtf file and return every occurance of the word into a RichTextBox. It returns the word and the scripture the word is in, but it also isreturning a bunch of weird text like: archan78988yykp etc etc. How do I onlyreturn the scripture with the searchedword, in this case the searched word is love. The code I am using is as follows:
<
If Line.Contains(Me.rtbSearch.Text) Then
'show search form

For example I only the second character in each line to be an x, while the 3nd to 10th character must be a hex digit.At the moment I use a Select Case, then check the position of the caret (using textbox.selectionstart) and see if the key being pressed is a "legal" character.Is there a better way of doing this as it slows down on large amounts of text.
This is the code I have at the moment:
Select Case TextBox1.SelectionStart
Case TextBox1.GetFirstCharIndexOfCurrentLine + 1

I have a series of text boxes on my form, and my client wants me to filter out characters that aren't allowed, for example in the name field you cannot have symbols or numbers.
Now, he wants it so when you try and put in a special character it simply will not get entered into the text box. I know the logistics to this, but I'm not sure how I would go about coding it.
Basically what needs to happen is when the user types in characters like $, ^, 5, * etc, a function needs to recognise this and stop them from being entered into the textbox, whether it means deleting them as soon as they go in or interrupting the action altogether.

I can not find the proper way to verify characters only in a text box.I am having a hell of a time trying to understand all that.I have 3 errors in my code.One error is "Error-Reference to a non-shared member requires an object reference."the other two errors are in reference to an explicit conversion from string to double.strName is what I am using as my variable for the input of the name in txtName.text Below is my full code. "----" are used to separate the classes.Attached documents are in .PDF format and HAVE TO BE FOLLOWED to the letter.Pages 2 & 3 contains the UML diagram as well as how the project should look and the structure chart for the code. I am not truly sure if my DisplayReservation is what will work to use in the list box.Is there any other reference I could get to help me understand how to use a list box as the project requires.[code]
