[Q] how to find process id on windows? (anyone have killProcName .py?)

[John Nielsen]

Even though it sounds simple, it's rather involved.

Here is a python COM object that works on NT and W2K:

from win32com.server.exception import COMException
import win32com.server.util

#print pythoncom.CreateGuid()

    # COM attributes.

win32pdh.PERF_DETAIL_WIZARD)

        except:
            raise COMException("Problem getting process list")
    def procids(self):
        #each instance is a process, you can have multiple processes
w/same name
        instances=self.proclist()
        proc_ids=[]
        proc_dict={}
        for instance in instances:

            else:

        for instance, max_instances in proc_dict.items():

#convert counter path to counter handle
                    win32pdh.CollectQueryData(hq) #collects data for the
counter
                    type, val =
win32pdh.GetFormattedCounterValue(counter_handle, win32pdh.PDH_FMT_LONG)
                    proc_ids.append(instance+'\t'+str(val))
                    win32pdh.CloseQuery(hq)
                except:
                    raise COMException("Problem getting process id")

        proc_ids.sort()
        return proc_ids

if __name__=='__main__':
    import win32com.server.register
    win32com.server.register.UseCommandLine(pyperf)
