    <p>I have built a windows service application by pywin32. And I can't create any files or directories in the directory '%LOCALAPPDATA%'. I think the reason leading to this problem maybe my app do not have enough privilege to create file, but I'm not quite sure about it. I am a beginner on Windows programming. How can I solve this problem?</p> <p>Here is my code:</p> <pre><code>import traceback import os import sys import win32serviceutil import win32security import win32api import win32service import win32event import win32file class newsLauncher(win32serviceutil.ServiceFramework): _svc_name_ = 'Test_service' _svc_display_name_ = 'Test for service' def __init__(self, *args): win32serviceutil.ServiceFramework.__init__(self, *args) self.hWaitStop = win32event.CreateEvent(None, 0, 0, None) def log(self, msg): import servicemanager servicemanager.LogInfoMsg(str(msg)) def sleep(self, sec): win32api.Sleep(sec*1000, True) def SvcDoRun(self): self.ReportServiceStatus(win32service.SERVICE_START_PENDING) try: cwd = os.path.join(os.environ['LOCALAPPDATA'], "test_service") os.mkdir(cwd) os.chdir(cwd) open("test.log", 'w').write("success create file.") self.ReportServiceStatus(win32service.SERVICE_RUNNING) win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE) self.ReportServiceStatus(win32service.SERVICE_STOPPED) except Exception as e: self.log('Exception: %s' % e) self.log('line %d' % traceback.tb_lineno(sys.exc_info()[2])) self.SvcStop() self.ReportServiceStatus(win32service.SERVICE_STOPPED) def SvcStop(self): self.log("in stop") self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING) win32event.SetEvent(self.hWaitStop) self.log("stoped") if __name__ == '__main__': win32serviceutil.HandleCommandLine(newsLauncher) </code></pre>

    1. COProbably has to do with the logon used for the service. See this Microsoft resource: http://msdn.microsoft.com/en-us/library/windows/desktop/ms677948(v=vs.85).aspx

    3. COI'd hazard a guess that the environment variable LOCALAPPDATA isn't actually set for a service. Does Python not provide a way to retrieve the path for a known folder? (In C you would use SHGetKnownFolderPath.)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
