Memory reading.

[Zer0Velocity]

Hey all, I have a little problem with reading from the memory of a program. The actual data I want from this app changes the address every time new data occurs within the program which means a new address ID.

So I was wondering if there was a way to use just part of the Hex code from 2220613D22 -> 2220793D22 which is always the same. So returns anything in between those numbers?

Thanks for any help.

Have a little respect for the forum and don't bump your thread within 24 hours of your last post.

You're using 10 char Hex? Since your question is in pseudo, I'll do the same with code:

For $i = 61 To 79
    _MemRead(.... Dec("20" & $i & "3D22"))
Next

I have used the following code but seem to have another slight problem, hopefully someone can help. What I want to do is search all addresses as the addresses always changing so need to search the whole memory. Here is the code currently not working with $id var.

For $id = Dec("00000000") to ("99999999")
    Next
For $i = 61 To 79
    _MemoryRead($id Dec("20" & $i & "3D22"))
Next
    If @Error Then
        MsgBox(4096, "ERROR", "Failed to read memory.")
        Exit
    EndIf
Next

That cannot be the code you're using? It would hard crash!

Edit:

And now you're changing things, first it was a specific address (or was that the value?) ... now you want to search the entire memory? I am actually working on something similar in another (lower) language. It takes a bit of time in that to search a processes entire memory there, I can't imagine what it would take in Autoit.

Yeah I need to search the whole memory for a specific value so 2220613D22 -> 2220793D22 would return whats in between those 2 codes. like for this it would start at " a=" and end at " y=" and return " a=Zer0Velocity" " y="

Hopefully this is a bit more understandable
