First,thanks anyone who answered me

That address include Pointer & Offset
I will be basic Read/Write Pointer & Offset, but i don't know how to do this...(unicode string)

There are no similar examples in Google search
How to read/write unicode string in VB.NET?

So you want to make a tool in VB.NET to change the name or what exactly is your question?

Yes,i want to make a tool in VB.NET to change the name
But,have no idea which way to turn....anyways
No anyone similar example can learn in google search

You can "convert" the name you want to a byte array like this:

Code:

Public Shared Function StrToByteArray(str As String) As Byte()
	Dim unicodeEncoding As UnicodeEncoding = New UnicodeEncoding()
	Return unicodeEncoding.GetBytes(str)
End Function

Then write that byte array to the process using WriteProcessMemory.

            Mem = AVA("ava", GetModuleHandle("ava", "ava.exe") + &H2406774, {&H90, &H0}, StrToByteArray(TextBox1.Text), 2)

            If Mem = True Then
                MsgBox("Success", 64, "Try")
            Else
                MsgBox("Failed", 64, "Try")
            End If
        Catch ex As Exception

        End Try

Where's i do wrong?

or some things i missed
This code are written on correct Address.
But,when I execute he always writes 1st string only...
ex:MPGH , only write "M" to processmemory

You are only passing the first byte of "Value" to your "WriteStr" function so why would you expect it to write anything else than just the first character?
Try this:

Code:

        Dim BytesWritten As IntPtr

    End Function

    Public Function ReadInt32(ByVal ProcessHandle As IntPtr, ByVal memAdr As Int32) As Integer
        Return BitConverter.ToInt32(ReadBytes(ProcessHandle, memAdr, 4), 0)
    End Function

    Public Function AVA(ByVal ProcessHandle As IntPtr, ByVal Address As Integer, ByVal Offsets As Integer(), ByVal Value As Byte()) As Boolean
        Try
            Dim Current As Integer = Address

                Current = ReadInt32(ProcessHandle, Current) + Offsets(i - 1)

            Return True

            If AVAProcesses.Length > 0 Then
                Dim Mem As Boolean = AVA(AVAProcesses(0).Handle, AVAProcesses(0).MainModule.BaseAddress + &H2406774, {&H90, &H0}, StrToByteArray(TextBox1.Text + vbNullChar))
                If Mem = True Then
                    MsgBox("Success", 64, "Try")
                Else
                    MsgBox("Failed", 64, "Try")
                End If
            Else

Thank you for making me understand somethings.
This code is definitely worth learning.
I can't express my gratitude enough.
