process

问题 I am writing a C# winform application that starts a second process to execute shell commands like "dir" and "ping". I redirect the second process's output so my app can receive the command result. It roughly works fine. The only problem is my winform app receives the command line output as a whole instead of line by line. For example, it has to wait for the external "ping" command to finish (which takes many seconds or longer) and then receives the whole output (many lines) at once. What I

问题 I want to make a Task Manager program that displays this information: Image name memory usage PID How can I do this? 回答1: You don't need the J(WS)CL therefore, there is a simple WinAPI call that does almost all you want, and this is CreateToolhelp32Snapshot . To get a snapshot of all running processes, you have to call it as follows: var snapshot: THandle; begin snapshot := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); Now you have a list of all running processes. You can navigate through

问题 I am trying to detect whether my process is being run in a debugger or not and, while in Windows there are many solutions and in Linux I use: ptrace(PTRACE_ME,0,0,0) and check its return value, I did not manage to perform the same basic check on Mac OS X. I tried to use the ptrace(PT_TRACE_ME,0,0,0) call but it always returns 0 even when run under gdb. If I change the request to PT_DENY_ATTACH it correctly stops the debugging but that is not what I want to achieve. Any ideas? 回答1: You can
