一、打开外部exe

1.use文件-SHELLAPI

2.ShellExecute(handle,'open','E:\test.exe','-s','',SW_SHOWNORMAL);

二、关闭外部exe

1.use文件-TLHelp32

2.新建两个函数

//查找正在运行的进程

function TForm1.FindTask(ExeFileName: string): Boolean;
const
PROCESS_TERMINATE=$0001;
var
ContinueLoop: BOOL;
FSnapshotHandle: THandle;
FProcessEntry32: TProcessEntry32;
begin
result := False;
FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
FProcessEntry32.dwSize := Sizeof(FProcessEntry32);
ContinueLoop := Process32First(FSnapshotHandle, FProcessEntry32);
while integer(ContinueLoop) <> 0 do
begin
if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) = UpperCase(ExtractFileName(ExeFileName))) or
(UpperCase(FProcessEntry32.szExeFile) = UpperCase(ExeFileName))) then
begin
Result := True;
Break;
end;
ContinueLoop := Process32Next(FSnapshotHandle, FProcessEntry32);
end;
CloseHandle(FSnapshotHandle);
end;

//关闭正在运行的进程

function TForm1.KillTask(ExeFileName: string): Integer;
const
PROCESS_TERMINATE = $0001;
var
ContinueLoop: BOOL;
FSnapshotHandle: THandle;
FProcessEntry32: TProcessEntry32;
begin
Result := 0;
FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
FProcessEntry32.dwSize := SizeOf(FProcessEntry32);
ContinueLoop := Process32First(FSnapshotHandle, FProcessEntry32);

while Integer(ContinueLoop) <> 0 do
begin
if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
UpperCase(ExeFileName)) or (UpperCase(FProcessEntry32.szExeFile) =
UpperCase(ExeFileName))) then
Result := Integer(TerminateProcess(
OpenProcess(PROCESS_TERMINATE,
BOOL(0),
FProcessEntry32.th32ProcessID),
0));
ContinueLoop := Process32Next(FSnapshotHandle, FProcessEntry32);
end;
CloseHandle(FSnapshotHandle);
end;

3.调用函数关闭进程（注意:ExeFileName是指exe的名称，不用带地址‘E:\’）

if FindTask('test.exe') then
  KillTask('test.exe');
