winapi - C++ ReadProcessMemory is Inconsistant -


i've used cheat engine retrieve base address value want change in memory in c++ program.

the address is:

base address: "threadstack0"-0000032c // threadstack0 exe file believe offset 1:     0x12e0 offset 2:     0x130 offset 3:     0xf00 offset 4:     0x500 offset 5:     0x298

i have following c++ code calculate base address:

uint_ptr modulehandle = (uint_ptr)getmodulehandle(null); uint_ptr addr = modulehandle - 0x32c; addr += 0x12e0; addr += 0x130; addr += 0xf00; addr += 0x500; addr += 0x298;  if (!readprocessmemory(hprocess, (lpvoid)addr, &powerup, sizeof(powerup), null)) {     cout << "failed read process memory" << endl; } else {     cout << "read process memory successfully" << endl; }

i run it, , 1 out of 10 times, have success. rest of time readprocessmemory fails.

why readprocessmemory inconsistant it's success? nothing on computer, keep running program , works, doesn't.

i pretty sure it's not fault of readprocessmemory, rather getmodulehandle(null) culprit. i'm not sure on how getmodulehandle works exactly, i'm guessing times works, when uses process memory address accessed last? , program runs findwindowa why works. , when doesn't work, that's because process's memory address accessed/changed between program calling findwindowa , getmodulehandle.

something along lines?

is there solution make program consistant in getmodulehandle(null) , readprocessmemory?

resizing Telegram inline keyboard -

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
