问题 I keep getting an error when I call EnumWindows(EnumWindowsProc, 0); Which converts my BOOL CALLBACK selectionWindows::EnumWindowsProc(HWND hWnd, long lParam) function into a parameter. I know it has something to do with the classes and selectionWindows:: but I can't figure it out for the life of me. Here is the .h #ifndef SELECTIONWINDOWS_H #define SELECTIONWINDOWS_H #include <windows.h> #include "mainwindow.h" #include <QWidget> #include <iostream> class selectionWindows : public QWidget {

Robocopy.exe is called from the batch script. Every other script or program ends as you'd expect. ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = "batch.bat"; startInfo.UseShellExecute = false; startInfo.CreateNoWindow = true; startInfo.RedirectStandardOutput = true;

问题 If you type the following string into a text file encoded with utf8(without bom) and open it with notepad.exe,you will get some weired characters on screen.
