Read/Write ProcessMemory of Private block

- 7.7k views
Hi. Making a new thread for this, but is actually a sub-problem coming from my other thread. I'm trying to make a loader (now in c++), which would use the ReadProcessMemory API. The process is created by the loader with CreateProcess(address,NULL,NULL,NULL,FALSE,CREATE_SUSPENDED,NULL,NULL,&startup_info,&process_info) I noticed, that while it reads the memory of an "Imag" memory block, it returns 0x00 (or 0xCC ?) when trying to read from a private memory area. How is this bypassable?

Lets say I have only one tab so then the thumbtrack should take the entire place in the hscroller and if I add more tabs then it should get smaller and smaller etc like in Notepad app for example.Next problem are the positions to set them correctly + calculate the right value to adjust everything you know.I made a example for testing.Maybe you can check this. invoke GetDlgItem,hWnd,IDC_HSCROLL mov…
