I'm outputting a number of variables to a text file and each field needs to be in a specific place.For example:I have a string that is varying in length, but will never be more than 5 characters. The string has to end on the 8th character of the line. Is there a way to write the string to ensure that the string ends at a specific place on the line, regardless of the length?
View 4 RepliesI have written a program which reads the text from the text file cleans it for some specific letters or phrases and then saves it in another text file. I am having a problem in rewriting the processed or cleaned data (after it has removed some phrases and characters)onto writing the file.
I have successfully written the text on the file except one problem. In each loop when each string is cleaned and is written on the text file, it overwrites the previous string. What I want is that it should write in the next line or in the same line.
My code is given below:
Private Sub btnopen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnopen.Click
FileOpen.Title = "Please select the file"
[Code]...
how can I write the text in the new line and avoid overwriting of text in my text file.
Well I basically know how to read a text file, replace text then write to one. how to append text after a specified string (ie, insert text at a specified line, removing the text after a string in a line and changing it without altering other lines, etc). Can someone please tell me how I would go about adding a string after a certain string in a text file? For example:
I Have:
test
example
hello
[Code]....
I can write a 1-d string array to file with:
Dim test() As String = {1, 2, 3, 4, 5}
File.WriteAllLines("C:MyFile.txt", test)
but can't see how to write a 2-d array to file.
I've tried this:
Dim test(,) As String = {{1, 2, 3, 4, 5}, {34, 22, 12, 33, 55}}
Dim myfile = File.CreateText("C:MyFile.txt")
Dim row, col As Integer

I want to create a little program with textboxes in it, that writes the contents of these textboxes to a file. It also needs to write some predefined lines to the files, even on the same line as where the contents of the textbox is.
Heres an example:
The file should look like this when you open it in notepad:
^1::
Send t Text from TextBox {Enter}
First I think I would need to do this:
Dim ioFile As New StreamWriter("scripting.ahk")
ioFile.WriteLine("^1::")
If I do the above it works.. But how can I write another line where the "Send t" and "{Enter}" gets written automaticly before and after the contents from the Textbox?
I am working with the formula for writing information to a text file. I have a program with 4 text box's and 5 radio buttons. I need to the program to write all of the info from the 4 text box's that the user has entered and the radio button that the user has selected.

I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?
View 3 Repliesbasically what I am trying to do is perform a loop that will write the input from an inputbox into the .txt file. My loop doesnt seem to be working,
[Code]...
far it works! But it work's too well. What I'm trying to do is insert a string of text at a certain index position of a text file, underneath a certain line of text. So far I have:
'Controls Var 16
If CheckBox1.Checked = True Then
If Mytempstring.Contains("zrandomtextz=0") = True Then
Mytempstring = Mytempstring.Replace("zrandomtextz=0", "zrandomtextz=1")
ElseIf Mytempstring.Contains("zrandomtextz=") = False Then
[Code]...
It's inserting the text, but it's inserting it at every line of text in the file. So instead of one instance of "zrandomtextz" underneath "xinserttextx" I get "zrandomtextz" before every single line in the file. Can someone please help me as this has been an issue for months now? Edit: There are quite a few lines above this one, as in 50-150, so I removed all of the above section, however I can assure you that whenever it is simply replacing then writing to file it works flawlessly, it's only now that I'm having problems and this is when I try to insert new stuff under stuff.
I've set the colour of a label using the ColorDialog and I want to read the chosen colour value into a string, using the following

I've made a function to convert a number and fraction string eg. "22 7/8" to decimal. I've no problem pulling the data from the current row cell to pass through the function.

The name of the cell i'm trying to pass the result back to is called "BaseDec".

I'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog
cat
baby
fish
tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?
I have a long UTF8 encoded text string. The actual values stored in the string are hexadecimal. I want to convert the encoding and save to a binary file.
Is there a simple encoding.convert or other method to do this with?
Basically the output is twice as large as it needs to be right now. The long way of doing it would be a routine to go through the string two characters at a time and convert to byte array and then .writeallbytes I guess. It seems there must be a simpler way of converting this?
Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.

View 1 RepliesI have seen a few different ways of Reading/Writing Text files. What i am trying to achieve is a simple debug file in the most efficient way possible. Currently I have....
If System.IO.File.Exists(debugpath) = True Then
Dim Debugwriter As New System.IO.StreamWriter(debugpath, True)
Debugwriter.WriteLine(debugwrite)
Debugwriter.Close()
[code]....
1. Do I have to close and reopen the file each time I want to write to it.
2. In vbscript I would simply open the the file at the start of the script and close at the end is the same possible here.
I've two Strings which I'm loading from a SQL Server 2008 database (nvarchar-field)After loading them from the database Visual Studio 2010 displays them as follows in the watch window:
str1 = "Test"
str2 = "Test"
But the comparison with str1 = str2 returns False If I write those strings to a file with UTF8 Encoding the result is as expected:
Test
Test
If I write those strings to a file with ANSI (Default) Encoding the result is NOT as expected:
?Test
Test
Converting the strings to bytes:
System.Text.Encoding.Default.GetBytes(str1) 'Returns ByteArray {63, 84, 101, 115, 116}
System.Text.Encoding.Default.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str1) 'Returns ByteArray {239, 187, 191, 84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
Where is the Byte 63 in case of ANSI Encoding OR Bytes 239, 187, 191 in case of UTF8 Encoding for str1 coming from?Well, Bytes 239, 187, 191 are the BOM for UTF8. The question here would more likely be: Why do I get the BOM for str1 but not for str2?(Well, the values are values passed to a webservice which inserts them into the database, the initial values are passed to this webservice by a client I've no control over)
This is my first post in the community. I am putting together a program that serves two functions:1. Takes input from TextBoxes and writes it to a text file.2.
