Reading from a memory address

[isaacboy]

Hi

I want to be able to get a value from a memory address, for example, address &H043HDDF holds 8, and I want to be able to retrieve that. I am able to write to an address:

Call WriteALong("xx", &H6D6280, 120)

Any ideas?

Here is the module I am using:

Public Const PROCESS_ALL_ACCESS = &H1F0FFF
Dim f1holder As Integer
Dim timer_pos As Long
