global-variables

问题 I've got some C code from a 3rd party vendor (for an embedded platform) that uses global variables (for speed & space optimizations). I'm documenting the code, converting to Doxygen format. How do I put a note in the function documentation that the function requires on global variables and functions? Doxygen has special commands for annotating parameters and return values as describe here: Doxygen Special Commands. I did not see any commands for global variables. Example C code: extern

问题 I'm trying to run some browser code in Node.js in order to simplify testing (deasync is the reason). Currently, I use jsdom to parse the only html file. At first, I was trying to make it also load the scripts, which are linked in <script> tags. But due to some stupid issues with relative file paths I have switched to passing a list of absolute paths to the script files as a parameter to jsdom.env function. Now I'm pretty sure that jsdom finds my scripts properly, but I cannot set any global

问题 I have a global variable g_user as string and a Label lb_welcome to show username, How can i create a global event when g_user changed then will trigger a function Private Sub Login() g_user = VerifyUser(id,password) lb_welcome.Text = $"Welcome {g_user}" End Sub I try to do something like this:- Private Sub RefreshLabel() lb_welcome.Text = $"Welcome {g_user}" End Sub Private Sub g_user_Changed(sender As Object, e As EventArgs) Handles g_user.Changed RefreshLabel() End Sub Above is just an

问题 I've read some other questions about this topic and many say that if I declare the variable varA outside my function (in de global scope), it is a global function, and so it is accessible for any function to use and update, right? Now, I have this example where I declare a variable outside a function, alter it inside the function, but when I call it outside the function, it displays as undefined , where if I'm to call it inside the function, it is altered. $(document).ready(function() { var

问题 I'm dealing with global variables in Python. The code should work fine, but there is a problem. I have to use global variable for instance of class Back . When I run the application it says that back is None which should be not true because the second line in setup() function - 'back = Back.Back()' # -*- coding: utf-8 -*- from flask import Flask from flask import request from flask import render_template import Search import Back app = Flask(__name__) global back back = None @app.route('/')

问题 I am learning Python and have read blogs about this error, but I am still not able to understand this clearly yet. This is a snippet of the code I am writing: for i in included: global signs,accounts, regions global sign_name, acc_name, rg_name if type == "regions": regions = i rg_name = regions['data']['region'] if type == "accounts": accounts = i acc_name = accounts['data']['account'] print("Stopping account " + acc_name + " in region " + rg_name) NameError: global name 'acc_name' is not
