在编写检测进程的程序的时候发现如下错误：
def check_exsit(process_name):
WMI = win32com.client.GetObject('winmgmts:')
processCodeCov = WMI.ExecQuery('select * from Win32_Process where Name="%s"' % process_name)
if len(processCodeCov) > 0:
print ('%s is exists' % process_name)
else:
win32process.CreateProcess('C:\Program Files (x86)\Tektronix\VectorVuPC\VectorVu-PC.exe', '', None, None, 0, win32process.CREATE_NO_WINDOW,None,None,win32process.STARTUPINFO())
print ('%s is not exists' % process_name)
失败报错
这个程序是在子线程中运行的，经过查询得知在子线程中运行WMI需要进行初始化,改为如下程序：
def check_exsit(process_name):
pythoncom.CoInitialize()
WMI = win32com.client.GetObject('winmgmts:')
processCodeCov = WMI.ExecQuery('select * from Win32_Process where Name="%s"' % process_name)
if len(processCodeCov) > 0:
print ('%s is exists' % process_name)
else:
win32process.CreateProcess('C:\Program Files (x86)\Tektronix\VectorVuPC\VectorVu-PC.exe', '', None, None, 0, win32process.CREATE_NO_WINDOW,None,None,win32process.STARTUPINFO())
print ('%s is not exists' % process_name)
