通过进程ID获取进程名

uses TLhelp32
function GetProcessNameById(const AID: Integer): String;
var
h:thandle;
f:boolean;
lppe:tprocessentry32;
begin
Result := '';
h := CreateToolhelp32Snapshot(TH32cs_SnapProcess, 0);
lppe.dwSize := sizeof(lppe);
f := Process32First(h, lppe);
while integer(f) <> 0 do
begin
if Integer(lppe.th32ProcessID) = AID then
begin
Result:= StrPas(lppe.szExeFile);
break;
end;
f := Process32Next(h, lppe);
end;
end
