问题 I have an eclipse plugin, which connects to a COM component using Jacob. But after I close the plugin entirely, the .exe file stays hanging in Windows processes. I use ComThread.InitMTA(true) for initialization and make sure that SafeRelease() is called for every COM object I created before closing the app and I call ComThread.Release() at the very end. Do I leave something undone? 回答1: Had the same problem with TD2JIRA converter. Eventually had to patch one of the Jacob files to release the

问题 I would like to run WMI queries from Go. There are ways to call DLL functions from Go. My understanding is that there must be some DLL somewhere which, with the correct call, will return some data I can parse and use.

I've examined the output of dumpbin.exe /exports c:\windows\system32\wmi.dll , and the following entry looks promising: WmiQueryAllDataA (forwarded to

问题 I have a JScript script that runs using cscript.exe . It creates a shortcut on the desktop (and in the start menu) that runs cscript.exe with parameters to run another JScript script.

问题 I'm using COM integration to drive MS Excel from Python 2.7. I noticed a peculiar thing: when I run the following bit of code: import win32com.client excelApp = win32com.client.dynamic.Dispatch('Excel.Application') an EXCEL.EXE process appears on the processes list (which view using the Windows Task Manager or subprocess.Popen('tasklist') ) as expected. I then do all the stuff I need to do no problem. However, when I close Excel: excelApp.Application.Quit() The process persists, even if I
