Hi,

I'm looking for a way to retrieve a process handle to feed into WriteProcessMemory. I do not want to retrieve the Messenger process (which can be done by GetCurrentProcess).

Does anyone know how-to?

What handle are you trying to retrieve?

The hProcess parameter to pass to WriteProcessMemory.

But are you trying to write to the Messenger process? If so GetCurrentProcess will work.

As I said in the first post, I'm not trying to retrieve the Messenger process handle.

BTW, I know the window title, (and by using FindWindow(Ex) I can get the window handle) and the EXE name.

If you know the window handle, then GetWindowThreadProcessId (returning a process id) and OpenProcess (returning a process handle from process id) should help.

However I don't know if you can write to arbitrary process's memory space ...(I don't think you can )

Well, it appears to work, except for the writing part. Access denied

er, is your process higher than the one you're writing to?

with winamp i do
GetWindowThreadProcessId
then
OpenProcess with the PROCESS_ALL_ACCESS flag
then you should be able to call
VirtualAllocEx (if you want to allocate memory within its space)
then
WriteProcessMemory

I can't seem to find PROCESS_ALL_ACCESS. I tried PROCESS_VM_WRITE instead. Still I receive the message "access denied".

Unless PROCESS_ALL_ACCESS is all these flags together (e.g. "FLAG1 | FLAG2" etc.), it's nowhere to be found.

Thanks mate
