Memory Hacking using pointer and offset(s)

Code:

WriteDMAInteger("Solitaire", &H38F910, Offsets:={&H14}, Value:=TextBox1.Text, Level:=1, nsize:=4)

but its not work . Can you give hints or working module to hack memory using offset and pointer ? Im soo sry for my bad English =(

The code is incomplete.
You need to put a Sub routine with these arguments like this:

Code:

Sub WriteDMAInteger(ByVal Process As String, ByVal ????? As ????, ByVal Offset As ?????, ByVal Input As String, ByVal level As Integer, ByVal ???? As ?????)
---
End Sub

Get the code and I will try to help you

        Return vBuffer
    End Function

End Module

Here is the module that i use in my project . Im using marked function , have a look pls . I seen this module in some youtube tutorials and they hacking memory by puting this part of code

Code:

WriteDMAInteger("Proc", &Haddress, Offsets:={&Hoffset1}, Value:=value, Level:=1, nsize:=4)

in button click event and the program works for them . For me its just nothing heppen when im click the button . My pointer and offset works fine in CE . As always sry for bad English )
