VB.NET Memory Module (by master131)
Someone originally asked me about how to write a float to memory and when he gave me his code, I immediately facepalmed since the decleration for WriteProcessMemory and ReadProcessMemory were completely wrong. I know it's not his fault because he probably copied from somewhere but here's my take on it.
It supports ANY 'primitive' value type, the most common one you guys will be using is probably: Integer, Single (Float) and String (string is not a primitive type but it's still supported). You can also read Byte() too (byte array), make sure to indicate how many bytes you want to read though.
Here's a full list if you're interested: Boolean, Byte, SByte, Int16 (Short), UInt16 (UShort), Int32 (Integer), UInt32 (UInteger), Int64 (Long), UInt64 (ULong), IntPtr, UIntPtr, Char, Double, and Single (Float).
Here's the code:
How do I use the code?
Right-click on your project and Add a new module. Then copy and paste the code from the box into the screen. If you want to use this module on another process, replace "iw5sp" with whatever you want next to 'TargetProcess'.
I've created a few functions for you guys. To check if a process is running, use the UpdateProcessHandle() function. For example (in a timer):
Now, here's how to read/write memory using this module:
Dim myIntValue As Integer = ReadMemory(Of Integer)(&H12345678) ' Reads the value from 0x12345678 as an Integer
Dim myFloatValue As Single = ReadMemory(Of Single)(&H12345678) ' Reads the value from 0x12345678 as a Single (remember that Single is the same as Float)
Dim myASCIIStringValue As String = ReadMemory(Of String)(&H12345678, 10, False) ' Reads 10 characters at 0x12345678 as a ASCII String
Dim myUnicodeStringValue As String = ReadMemory(Of String)(&H12345678, 10, True) ' Reads 10 characters at 0x12345678 as a Unicode String
Dim myByteData() As Byte = ReadMemory(&H12345678, 12) ' Reads 12 bytes from 0x12345678
WriteMemory(&H12345678, 10I) ' Writes 10 as an Integer to 0x12345678, take note of the I at the end (it's optional but you can put it there just incase)
WriteMemory(&H12345678, 0.5F) ' Writes 0.5 as a Single to 0x12345678, take note of the F at the end! (you MUST do this or it will assume it's a Double!)
WriteMemory(&H12345678, "Hello World", False) ' Writes Hello World as an ASCII string to 0x12345678
WriteMemory(&H12345678, "Hello World", True) ' Writes Hello World as a Unicode string to 0x12345678
WriteMemory(&H12345678, New Byte() { &H90, &H90, &H90, &H90 }) ' Writes '0x90, 0x90, 0x90, 0x90' as a byte array to 0x12345678
How do I write a number into memory if I'm going to get it from a text box?
It is extremely important that you let VB.NET know what type you want to write into memory otherwise it may assume and you might get some nasty results, here's how you can do it:
However, if you are 100% sure that whatever inside a box is a number and not letters you can do this:
What's the difference between a ASCII and Unicode string?
Unicode strings use 2 bytes for every letter it uses and ASCII only uses 1 byte for every letter. If you find a string in memory with Cheat Engine with the Unicode box unticked then it's a ASCII string. If the Unicode box is ticked then it's a Unicode string.
It supports ANY 'primitive' value type, the most common one you guys will be using is probably: Integer, Single (Float) and String (string is not a primitive type but it's still supported). You can also read Byte() too (byte array), make sure to indicate how many bytes you want to read though.

It is extremely important that you let VB.NET know what type you want to write into memory otherwise it may assume and you might get some nasty results, here's how you can do it:
Code:

Dim floatValueToWrite As Single

Code:
WriteMemory(&H12345678, CInt(TextBox1.Text)) ' Writes the value inside a TextBox as a Integer WriteMemory(&H12345678, CSng(TextBox2.Text)) ' Writes the value inside a TextBox as a Single

Still, it do look very alike the one that was posted a long time ago here. (Page 2 in tutorials I think...)
Nice work Master
ill gona try this
Thats for that awesome source.
Everything works fine, except reading the adresse as string.
as example:
Returns an error here:
=> MissingMethodException
I'm thankful for any solution.
Btw, a bad solution is returning a bytearray which will be enocoded as string with an external function.

Hello, i have a question, how to use pointers with "ReadMemory()"? 
Also, i am getting the => MissingMethodException too.
Thanks in advance.
Also, i am getting the => MissingMethodException too.
Thanks in advance.
People where saying that strings weren't working, I've fixed it now. Also, if strings still have some of the old text at the end, please make sure to add vbNullChar at the end of the string.
Example:
WriteMemory(&H12345678, "Hello World" + vbNullChar, False)
Example:
WriteMemory(&H12345678, "Hello World" + vbNullChar, False)
