IO.File.Move

Example:

Code:

IO.File.Move(Application.ExecutablePath, "C:\moved.exe")

Format:

Code:

IO.File.Move(SourceFileName, Destinationfilename)

IO.File.Open & IO.File.OpenRead & IO.File.OpenText & IO.File.OpenWrite

Explanation: Open's a file for either reading or writing to it.

Example:

Code:

IO.File.Open("C:\file.exe", IO.FileMode.Open)

IO.File.ReadAllBytes & IO.File.ReadAllLines & IO.File.ReadAllText

Explanation: Opens a file to read its byte array or all Textlines or its text.

Example:

Code:

Dim aByteArray As Byte() = IO.File.ReadAllBytes("C:\file.exe")
Dim aStringArray As String() = IO.File.ReadAllLines("C:\text.txt")
Dim aString As String = IO.File.ReadAllText("C:\text.txt")

Format:

Code:

IO.File.ReadAllBytes(Path)
IO.File.ReadAllLines(Path)
IO.File.ReadAllText(Path)

IO.File.Replace

Explanation: Rewrites a existing file and makes a backup of it.

Example:

Code:

IO.File.Replace(Application.ExecutablePath, "C:\copy.exe", "C:\backup.exe")

Format:

Code:

IO.File.Replace(SourceFileName, DestinationFileName, DestinationBackupFileName)

IO.File.SetAttributes

Explanation: Sets or changes a file's attribute.

Example:

Code:

IO.File.SetAttributes("C:\Unhidden.exe", FileAttribute.Hidden)

Format:

Code:

IO.File.SetAttributes(Path, FileAttributes)

IO.File.SetCreationTime & IO.File.SetCreationTimeUtc & IO.File.SetLastAccessTime & IO.File.SetLastAccessTimeUtc & IO.File.SetLastWriteTime

Explanation: Can set a file's creation date, the same date and time it got created or its last opened date and time or its last Edited time. Very useful for virus makers to fool the opener to think the binded file's creation date is like 2 years ago.

Example:

Code:

IO.File.SetCreationTime("C:\file.exe", Date.Today)
IO.File.SetCreationTimeUtc("C:\file.exe", Date.UtcNow)
IO.File.SetLastAccessTime("C:\file.exe", Date.Now)
IO.File.SetLastAccessTimeUtc("C:\file.exe", Date.Now)
IO.File.SetLastWriteTime("C:\file.exe", Date.Now)

Format:

Code:

IO.File.SetCreationTime(Path, Date)
IO.File.SetCreationTimeUtc(Path, Date)
IO.File.SetLastAccessTime(Path, Date)
IO.File.SetLastAccessTimeUtc(Path, Date)
IO.File.SetLastWriteTime(Path, Date)

File.Attributes: The Properties of files. The VB Attributes are:

• FileAttribute.Archive
  
• FileAttribute.Directory
  
• FileAttribute.Hidden
  
• FileAttribute.Normal
  
• FileAttribute.ReadOnly
  
• FileAttribute.System
  
• FileAttribute.Volume
  

Boolean: The Conditions that can connect codes. There are known booleans as:

• True ( Saying something is True )
  
• False ( Saying something is False )
  
• = ( Saying something is equal to another Code )
  
• <> ( Saying something is not equal to another Code )
  
• < ( Saying something is bigger then the Code's value )
  
• > ( Saying something is smaller then the Code's Value )
  

Examples:

Code:

If IO.File.Exists("C:\file.exe") = true then
If IO.File.Exists("C:\file.exe") = false then
If integer = 1 = true then
If integer <> 1 = true then
If integer < 1 = true then
If integer > 1 = true then

Have a Great day

Imports System.IO

Nice guide!!! I really like it!!!

btw, in the boolean, you use double checking, which is not necessary

Spoiler:

Code:

If integer = 1 = true then

The code will be read:

If integer is 1 = true = true then

Boolean is set as "true" by default

That means, its more simple to use:

Code:

If integer = 1 then

it will be read:

If integer is 1 = true then

However, for boolean false you will need it

so:

Code:

If integer = 1 = false then

will be read:

If integer is 1 = false then

[1234hotmaster]

well, still even double checking works

Glad you liked it. More guides to come

Yeh, but it slows down the process a little bit. And also more words = more complicated

Looking forward for more great guides!!!!!!!

Nice thread, keep it up.

You can show the return values more clearly like:

Code:

Dim aByteArray As Byte() = IO.File.ReadAllBytes("C:\file.exe")
Dim aStringArray As String() = IO.File.ReadAllLines("C:\text.txt")
Dim aString As String = IO.File.ReadAllText("C:\text.txt")
