asp.net - Combining multiple IndexOf -

-

Is there a way to combine multiple indexes () to make it more compact? 

  String as a slow UserAgent = HttpContext.Current.Request.UserAgent if not (UserAgent.IndexOf ("chrome")> 1) OrElse (UserAgent.IndexOf ("Safari ")> -1) Then, 'this end if    
 
 
 you enter   instead of  can use indexOf  and a collection to view: 
 
  dim browser = {"chrome", "safari"} if not browser . If any (function (b) UserAgent.Contains (b)) then terminate with  
 
 or query syntax: 
 
  dim matching browser = browser In the browser, where UserAgent.Contains (Browser) is not MailBurners. If any () then end

python - Strange behavior using PyQt4's 'pyqtSlot' decorator before another decorator -

-
I have a strange problem with using the QtCore.pyqtSlot decorator in front of the function decorated with a different decorator. The problem below shows this problem, it immediately provides a low QT program with a single button. When pressing a button, the following happens: (1) The signal 'signal_A' and 'signal_B' sequence are connected to method_A and method_B ​​respectively. (2) signal_A and signal_B signals are emitted. (3) The required behavior is that the method_A and method_B ​​are executed. However, it turns out that both signal_A and signal_B trigger method_A, or method_B ​​(oddly, this is nondeterministic, and different for each part of the program!). It appears to be a bug. This issue is present when PyQt4 binding is used in Qt. It is not present when using PySide (use the '-pyside' parameter to verify) I have seen both problems in Python 2 and 3, and both in Windows and Linux This issue is related to the insertion of a decorator be...

Message + environment. Newline); }} Maybe you search for the behavior provided by Applic...

When I try to kill with a command prompt, I get the message: "Access denied" I tried to run as my app administrator and the process was killed. How can I not always use "Run as administrator"?
