类似于这个问题,但在Delphi中：
解决方法
从：

uses TlHelp32;
function processExists(exeFileName: string): Boolean;
var
ContinueLoop: BOOL;
FSnapshotHandle: THandle;
FProcessEntry32: TProcessEntry32;
begin
FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
FProcessEntry32.dwSize := SizeOf(FProcessEntry32);
ContinueLoop := Process32First(FSnapshotHandle,FProcessEntry32);
Result := False;
while Integer(ContinueLoop) <> 0 do
begin
if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
UpperCase(ExeFileName)) or (UpperCase(FProcessEntry32.szExeFile) =
UpperCase(ExeFileName))) then
begin
Result := True;
end;
ContinueLoop := Process32Next(FSnapshotHandle,FProcessEntry32);
end;
CloseHandle(FSnapshotHandle);
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
if processExists('notepad.exe') then
ShowMessage('process is running')
else
ShowMessage('process not running');
end;
