• C++ increment with macro

  I have the following code and I want to use increment with macro:

  #include <iostream>
  
  #define ABS(x) ((x) < 0 ? -(x) : (x))
  
  int main(int argc, char** argv)
  {
      int x = 5;
      const int result = ABS(x++);
  
      std::cout << "R: " << result << std::endl;
      std::cout << "X: " << x << std::endl;
  
      return EXIT_SUCCESS;
  }
  

  But output will be incorrect:

  R: 6
  X: 7
  

  Is it possible to somehow use macros with an increment, or should this be abandoned altogether?

• How to assign two or more values to a QMap Variable in Qt

  I am getting confused of how to store the values assigned from 3 different functions and storing them in a single map variable

  QMap<QString,QString> TrainMap = nullptr;   
  if(......)    
  (    
         TrainMap    =    PrevDayTrainMap();
         TrainMap    =    NextDayTrainMap();
         TrainMap    =    CurrentDayTrainMap();
  }
  

  The PrevDayTrainMap,NextDayTrainMap & CurrentDayTrainMap returns a set of values with Date and the TrainIdName.I need to store all the values from prevday,currentday and nextday in the TrainMap but it stores only the currentday values to the TrainMap as it is assigned at the last.I am not sure what to do so that it doesn't overwrite.If I should merge what is the way to do it?
• Write a program using Multithreading in C++ while using pthread_join()?

  Write a program in the shell using threads. Each thread must be doing one of the tasks mentioned below. One task must be completed and then another task should be started. Use pthread_join() system call to make the thread wait for the other thread's completion. Get the input at the start and use these numbers in all threads. The numbers must consist of four digits at least. i.e 1234. a) Finding the largest of three numbers b) Reversing the largest number c) Sum of individual digits of a 4-digit number (1234 -> 1+2+3+4=10)

• Will volatile work for Collections and objects?

  Trying to understand the theory about volatile. They say, volatile provides happens-before, so changes done in thread 1 should be visible in thread 2.

  What if we will put volatile for Collection? Will java provide visibility in Thread 2 for changes done in Thread 1 ? And why?

  public class Vol {
      volatile List<String> list = new ArrayList<>();
      
      // thread 1
      public void put(String s) {
          list.add(s);
      }
      
      // thread 2
      public List<String> get(){ // all changes are visible? "Why" for No\Yes answer
          return list;
      }
  }
  
• how to get a list of available monitors in windows 10

  I want to get a list of available monitors in Windows 10, same as the monitor list shown in the System display settings (no matter whether they are attached or unattached), just like this:

  

  I use EnumDisplayDevices() to enumerate all displays, but there is no proper flag indicating whether the display is available.

  So, how can I do this?
• Prevent window from being clicked in while another window is open

  On Windows, when a window opens on top of another window, the parent window will not be clickable, and will make a "ding" sound and its titlebar will flash. It will do this until the other window is closed. How do I recreate this in Win32?
• Should Google OAuth 2.0 access token be stored in appdata, or stored using LsaStorePrivateData for login caching

  Where would the best place be to store a Google OAuth 2.0 access token on Windows for login caching? Would it be appropriate to store the access token in %APPDATA%, or should LsaStorePrivateData(), and LsaRetrievePrivateData() be used in a plugin (Storing Private Data)? The general procedure for the app is listed below.

  1. Get access token from google using googleapis_auth (Installed/Console Application)
  2. Send google access token to server for verification that the access token is valid and from an authorized user
  3. If the user is authorized, save the access token to disk, and user performs tasks in the application. While the app is running, the access token is refreshed, and saved to disk when refreshed
  4. The user exits the application, but doesn't logout
  5. When the app is re-opened, the access token is loaded from disk and sent to the server for authentication and verification, repeat step 3

  Note that the verification of the access token confirms that the access token isn't expired.
• Is there a better way to Save the files in Visual Studio?

  After making some changes in xyz.cpp file, when I am trying to save the whole project it asks to save files in the directory and ultimately it didn't get saved and an error message comes as

  The Process cannot access the files "c:\ml/src.cpp" because it is being used by another process.

  Usually to get rid of this error I use to open another .cpp file and make some chnages in that and then try to save so that other unsaved files gets save with this and sometimes it didn't work well. was wondering if there is any better way of handling it?
• CListCtrl did not show text immediately like StaticText

  I have a code like this to write install log to a static text and a list control, and i have a button to start the installer that be handle by function OnClickInstallBtn() but every time I call the WriteLogtoScreen(), only the static text change and nothing show up in the list until the OnClickInstallBtn() is done and everything on that list show up all at one.

  How can i make it show up right away like the static text?

• Python reroute other scripts that automate applications to other\multiple monitors

  I am a beginner to programming. I have a few of these python scripts that actually run some applications to my machine. Recently, I have been requested to run these scripts to the other monitors for example if I got 4 monitors, there will be a script that receive a few arguments such as the python scripts that run the requested application and also which monitor that I want it to be run.

  I found that there is a way to automate these by using .ahk language. So this is what I have done:

  sysget mon1, monitor, 1
  sysget mon1, monitor, 2
  sysget mon1, monitor, 3
  sysget mon1, monitor, 4
  
  if WinExist ("ahk_exe Calculator.exe")
     WinActivate, ahk_exe Calculator.exe
  winmove A,, mon2left, mon2top, (mon2right - mon2left), (mon2bottom - mon2top)
  
  return
  

  But the problems are, I am not sure how am I going to integrate this with Python, how this .ahk script will receive variable value of the windows title which I retrieved using python script and also there might be a few arguments value that I would like to pass through.

  Is it possible to be done or is there any way that I can do it completely only using Python?
• python - launcher excel and show spec location

  I want to open Excel with Python in the appropriate location, e.g: sheet2, A120.

  I read somewhere that it is possible if I indicate the appropriate location during the initial closing.

  I currently have this code:

      wbkName = r'engl-Copy.xlsx'
  os.startfile(wbkName)
  hwnd = win32gui.GetForegroundWindow()
  win32gui.ShowWindow(hwnd, win32con.SW_MAXIMIZE)
  

  But it always opens A1. I want to open A120 (sheet2).

  Thanks in advance..
