Hi again
is there a possibillity overwrite values (bytes) in the memory with PureBasic? For example writing new bytes on a adress like this one: 00401022 (memory of another process)

or if you want to write into a Programms Codememory see Topic 'Selfmodified Codeexample' under Tips & Tricks.
Its a long way to the top if you wanna .....CodeGuru

Sure you can! Here's a Visual Basic example, which you should easily be able
to convert to PureBasic:

If hwnd = 0
MessageRequester("","Window not found",0)
EndIf
proid.l=GetWindowThreadProcessID_(hwnd,pid)
pHandle.l = OpenProcess_(PROCESS_ALL_ACCESS, False, pid)
The pHandle is every time i run this code zero ?! Any ideas why or how to translate the API funtions to PureBasic in an other way?

Ummm.... you aren't using any constants for starters.
I could be wrong but win API declares PROCESS_ALL_ACCESS as something like:
#STANDARD_RIGHTS_REQUIRED=$F0000
#SYNCHRONIZE=$100000
#PROCESS_ALL_ACCESS=#STANDARD_RIGHTS_REQUIRED|#SYNCHRONIZE|$FFF
and GetWindowThreadProcessId as:
Code: Select all
DWORD GetWindowThreadProcessId(
HWND hWnd, // handle of window
LPDWORD lpdwProcessId // address of variable for process identifier
);
so maybe...??
hWnd=FindWindow_(0,"Calculator")
proid=GetWindowThreadProcessID_(hWnd,@pid)
and maybe...
pHandle.l = OpenProcess_(#PROCESS_ALL_ACCESS, 0, pid)
I'm not saying this will work, but it's probably closer than what you have there.
Fred would probably know best

Stick a # in front of the PROCESS... constant, and it should work.
If not, you'll need to declare the constant, as Paul said in his post.
Oh, and wherever Visual Basic has vbNullString, that just means "" in
PureBasic (ie. an empty string). And 0 for vbNull.
