问题 I am really impressed by this MarlIO project and want to implement something similar using Python. However, I got the emulator OpenEmu working, however, I don't know how to control the game using Python. Isn't it just a matter of sending a few keystrokes?! Man, it is not that straightforward on a Mac. In [41]: cmd1 Out[41]: '\nosascript -e \'tell application "System Events" to key code 48 using {command down}\' \n' In [42]: cmd2 Out[42]: '\nosascript -e \'tell application "System Events" to

问题 I need to receive an event when some process starts using the camera. I did this through CMIOObjectGetPropertyData. But it does not work correctly, the correct value is only the first time it is accessed. I also tried to use the CMIOObjectAddPropertyListenerBlock but he did not work it from me. Tell me please, what am I doing wrong? I will be very grateful. while (1) { UInt32 value = 0; UInt32 valuePropertySize = sizeof(flag); CMIOObjectPropertyAddress opa =

问题 I cannot get rid of the error below. Installed homebrew via /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" brew install mysql mysql.server start gives the error: ERROR! The server quit without updating PID file (/usr/local/var/mysql/ username .lan.pid). Some things I have tried: ps -ef | grep mysql outputs: 501 1196 1172 0 9:08PM ttys000 0:00.00 grep mysql which I then try to kill with kill -9 1172 . This just says Process Complete but then

问题 I see that DateComponents has an Instance Property isLeapMonth. It appears to be a setter property. What I'd really like to know is given a year, is a month a leap month. Is this possible in the API, or do I need to implement my own algorithm to do so? Many thanks in advance. 回答1: You can check if the first day of the month in question, when set to leap, is a valid date or not: func isLeap(month: Int, year: Int, era: Int, calendar: Calendar) -> Bool { var components = DateComponents()

问题 Although this is happening within a Xamarin.Mac project, I think the issue is more to do with MacOS, as the signs are that of App Nap. In my AppDelegate.cs file, I have this: public override void DidFinishLaunching(NSNotification notification) { _activity = NSProcessInfo.ProcessInfo.BeginActivity( NSActivityOptions.Background | NSActivityOptions.LatencyCritical, "You charge $3,500AUD for this laptop and yet " + "can't provide enough resources for a smooth " + "operation of this app in the

问题 I'm trying to implement drag&drop functionality in my app and I ran into a problem of my mouseUp event not firing. It fires just fine if I simply click and release on my view, but if I do drag, my mouseDragged event fires and that's it. By trying different things I figured out that the problem is in my dragImage call, but I don't know how to solve it for now. Here is my code: -(void) mouseDragged:(NSEvent *)theEvent { isDragging = YES; if ([selectedCellRowIndex longValue] >= 0) { NSImage *im

问题 I'm just getting started downloading all my programs. I ran into an issue I didn't understand that was resolved using this stackoverflow thread. It worked perfectly. I then followed the basic instructions on this page and when I got to step 4 rails new test_app I received the following error. /Users/Hansen/.rvm/rubies/ruby-2.1.3/lib/ruby/2.1.0/rubygems/dependency.rb:298:in `to_specs': Could not find 'railties' (>= 0) among 8 total gem(s) (Gem::LoadError) from /Users/Hansen/.rvm/rubies/ruby-2

问题 I am about to figure out how exactly a programm stack is set up. I have learned that calling the function with call pointer; Is effectively the same as: mov register, pc ;programcounter add register, 1 ; where 1 is one instruction not 1 byte ... push register jump pointer However, this would mean that when the Unix Kernel calls the main function that the stack base should point to reentry in the kernel function which calls main. Therefore jumping "*rbp-1" in the C - Code should reenter the

问题 I'm trying to get a macro that works perfectly in Excel 2011 for Mac to work in Excel 2016 for mac. The goal is to have the user specify a folder with .csv files in it, and then the macro loops through all the .csvs, opening each to copy information out of it into another Workbook. The macro fails when trying to open the first .csv file in the user-chosen folder, with a 1004 error, file cannot be found. (side note: Earlier in the macro, workbooks.open works perfectly with a user selected FILE
