I am trying to write a code that will byte swipe data in a string.
The conversion should take a 16 characters string, and swipe the first to characters with the last two, then characters three and four with character thirteen and fourteen and so on, in this format if the input string is
A1B2C3D4E5F6G7H8 then the converted sting will be H8G7F6E5D4C3B2A1.
I run into problem using: left(mystring 2) and right(mystring -2) because the string to manipulate is an input of a textbox so I fail when I try to use cross data with a StringHandling class, and how to incorporate StringHandling into my form class and without it when I try something like
Dim byte1 As String = Left(MyString, 14)I get an
error saying - Public ReadOnly Property Left As Integer has no parameters and its return type cannot be indexed.
How do you manipulate a text file once you have opened it with Streamreader? I can get the streamreader to open the file and display it in a text/listbox but i cant do things like split and join to it.... It has no effect on the text file when viewed.
This is how i am setting up my string array:
Dim fileName As String = "C: est.txt"
Dim objReader As New System.IO.StreamReader(fileName)
how do I manipulate objReader as a string?
I am not sure if this makes sense or not, but I need to process raw text (without any encoding?) that I retrieved from a file recovery application "PhotoRec".With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.[code]I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "current byte". So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

I'm implementing a feature which reads comma separated txt file from server(one line at a time). Format of file is fixed, There are 3 columns on each row. After reading the row from file I insert it in a database table. But first value of each row aoutomatically appends two blank spaces, even if there are no blank spaces at the begining of each row. I tried to use "TRIM/LTRIM/Replace" to remove blank spece from the first value of each row, but didn't succeed.

I have a problem to implement action button to execute bat file . I am using SharpDevelop Version : 3.2.0.5698 . this code looks like :
Sub Button3Click(sender As Object, e As EventArgs)
Shell(Environ$("CONFIG") & "wpis_v3.bat")' TODO: Implement Button3Click
End Sub
in wpis_v3.bat I have :
@echo off
%DIR%instatus.bat >> %DRIVE%users
eport.txt
status.bat launches script to check license availbilty on the server and write it to report.txt ... by launching just wpis_v3.bat it works . report is generated with all information about licenses . But when I launch from VB icon - report file is generate but is total empty . I observed that with any bat which contains >> VB doesn't write into file. Is there other way to acchive it ? I would like that VB will show only specific lines from this report.txt - which contain string : "Site" and other "Client" .

View 4 RepliesOutlook is causing some problems when being passed a mailto string with accented characters in it. Changing the codepage for my entire webpage that has this string on it solves this problem, but that causes other problems in the system, so I would not like to do that.
A string like such returns a lot of garbage characters:
"mailto:Helpdesk-someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
Meanwhile, this cuts off the character after the "D"
"mailto:someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
I am writing a library in VB.NET in which I have added, among others, a class originally written in C# but converted into VB.NET. I don't know much about C# so therefore I have used online C# to VB.NET-converters. Now I am stuck with some code which I believe the online-converter was not able to "translate" properly.
