This article illustrates how the VC implementation captures the currently running process. Share with you for your reference. The specific implementation method is as follows:

#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>
int main(int argc,char* argv[])
{
PROCESSENTRY32 pe32;
//Define the size of the structure before you use it again
pe32.dwSize=sizeof(pe32);
//Take a snapshot of all the processes in the system
HANDLE hProcessSnap=::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
if (hProcessSnap==INVALID_HANDLE_VALUE)
{
  printf("Create ToolHelp32Snaphhot Call fails !n");
  return -1;
}
BOOL bMore=::Process32First(hProcessSnap,&pe32);
while(bMore)
{
  printf(" Process name :%sn",pe32.szExeFile);
  printf(" process ID No. :%unn",pe32.th32ProcessID);
  bMore=::Process32Next(hProcessSnap,&pe32);
}
printf(" Don't forget to clear it out snapshot");
::CloseHandle(hProcessSnap);
return 0;
}

Hope that this article described the VC programming for you to help.
