Any idea why that is happening and how I can resolve it? I am trying to call the same inside the hook procedure GetMsgProc as mentioned below: LRESULT WINAPI GetMsgProc(int nCode, WPARAM

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 {

问题 I have this code on windows which is working with A4 printers. But i have a very small printer, when i print something it does not print anything but only push the ticket out.

问题 So basically I am using the windows api to create an emty window and then I use OpenGL to draw to that window from different threads. I managed to do this just with one thread , but getting and dispatching system messages so that the window is usable was slowing down the frame rate I was able to get, so I'm trying to get another thread to do that in parallel while I draw in the main thread. To do this I have a second thread which creates an empty window and enters an infinite loop to handle

问题 My .NET 5 console application registers a HandlerRoutine by using SetConsoleCtrlHandler, so it can do some cleanup before exiting. This allows me to react to CTRL+C / CTRL+BREAK , ALT+F4 and the console being closed using the X button.

问题 On Windows 10 calling LoadIcon asking for the standard icon IDI_INFORMATION yields this icon: On the other hand, calling MessageBox passing IDI_INFORMATION produces a dialog that uses this icon: How can I obtain the second icon, if the obvious call to LoadIcon does not do so? 回答1: This feels like a bug in user32.dll but Windows 8 has the same issue so I guess Microsoft doesn't care. You can get the flat icon used by MessageBox by calling SHGetStockIconInfo: SHSTOCKICONINFO sii; sii.cbSize =
