Re: How to write a text file?


Thanks eBob

I'm looking at what i wrote and figured out that I should just change
the line I want to instead of just creating the file from scratch. So
poking around I ended up finding a Search and replace piece and i'm
using that. I'm not sure though if I should keep it as a class or do
I build it right into the form? SO far I'm getting pretty confused in
the UI and how to create something in Visual Studio. Although I
prepared for general confusion when I bought it, I didn't realise how
extremely different from batch/wsh/VBScript/Qbasic/Visual Basic it
would be. I'm looking around for a course now...

=============== ============
'
' sr = search and replace
'
Dim sr As StreamReader = New StreamReader( "autorun.in i" )
Dim fileText As String = sr.ReadToEnd()
Dim i As Integer = fileText.IndexO f("action4=\Doc umentation\Kit
\installplaceho lder.html")
fileText = fileText.Remove (i, 1)
fileText = fileText.Insert (i,"exelocation _TextChanged")
sr.Close()

I would have started with Hello World, but to each his own. *But be aware
that the VS IDE can take a little bit of getting used to.

A nice thing about the VS IDE is the built in Help. *I just did a searchfor
"File i/o" and selected "Basic File I/O" from the hits and am looking at a
nice discussion of, well ..., basic file I/O. *(There are many things I
don't care for about the Help facility but it does contain a wealth of
information.)

The SAMS books lack depth, but if your programming experience is really
limited one of their books might be a good place to start.

Here's some code which I abstracted from a working program of mine.

* * * * Dim sw As StreamWriter * * * * * * *'for theoutput history file
* * * * Dim hisline As String * * * * * * * 'line tobe written to the
history file

* * * * sw = New StreamWriter(gl obalinf.ExcelFi leName + ".his") * 'for the
output history file

* * * * sw.WriteLine(hi sline)

* * * * sw.Close()

To use it you will also need an "Imports" statement ...

* * * * Imports System.IO

I'd recommend always using these two statements as the first two statements
in your source file:

* * * *Option Explicit On
* * * *Option Strict On

These two statements tell the compiler to catch your dumb errors at compile
time rather than allowing them to cause really confusing errors at run time.
(Although you will still experience really confusing errors at run time.)

Good Luck, *Bob

Hi, I have these string data: str_data1, str_data2, str_data3, which capture some value after a routine process A. Then I would like to write (append) these 3 string values into a text file each time after routine process A, the text file is named "mytext.dat" in following format with "#####" as separator. The maximum entries of them is 5. When reaching the fifth entry, it will delete the very first entry.

Hi there, What is the maximum length that one line can hold in a text file using StreamWriter's Write or WriteLine method? If the string is too long for one line to hold, what will Write or WriteLine do? In order me to retrieve data correctly from the text file later, I have to know the right index. For the following code,if str1's length exceeds one line in text file, how can I get str2's index when reading the text file? Is there...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
