hwnd

问题 I'm trying to use function SetForegroundWindow(HWND hWnD) . I have some handles but it's not working as parameter of above function. My handle is a thread and I want to run it in foreground. What are the differences between a HWND and a HANDLE? 回答1: They are just abstract data types. According to MSDN, HANDLE and HWND are defined as: HANDLE is a handle to an object. HWND is a handle to a window. So, a HWND is a HANDLE , but not all HANDLE s are HWND . In fact: typedef void *PVOID; typedef

问题 I'd like to get a list of all the windows every time a new window is created. For now, I'm using a timer which gets an enumeration of all the windows. But I'd like to avoid using a timer, and subscribe to any kind of event that is triggered when a window (or a process) is created... How could I do this? 回答1: You can monitor all Window creating processes using SetWindowsHookEx with a CBTProc 来源： https://stackoverflow.com/questions/40697822/list-windows-and-detect-new-windows

问题 I know the actual button's handle. What I would like to check if that button was clicked and if so that would trigger an autohotkey script. Thanks in advance! 回答1: You are right. You can use this instead of ImgSearch. ControlGetPos, x, y, w, h, button1, ahk_class CalcFrame MsgBox, %x% %y% %w% %h% return So you would have to run the ControlGetPos after each mouse click (only when the target window title is active) and then compare the actual mouse coordinates with the button click area.

问题 I'm going nuts here... How do you find the "hwnd" value of a CommandButton , in an Excel 2007 Form ? I've Googled, I've tried all kinds of suggestions (most of which suggest that a command button has a .hwnd member property - but it doesn't) and haven't found an answer. I can get the Form's hwnd value, and (in theory) should be able to use a EnumChildWindows to find sub-windows, including my button, but this also doesn't work. Has anyone managed to do this ? 回答1: I'm afraid you can't, MS

问题 I would like to get the winId of a qml window. I have the following files. main.qml : import QtQuick 2.5 import QtQuick.Window 2.2 import QtQuick.Controls 1.4 Window { id: myMainWindow title: "MyMainWindow" width: 200 height: 200; visible: true Component.onCompleted: { x = 40 y = 40 } } and my main.cpp : #include <QGuiApplication> #include <QQmlApplicationEngine> #include <QWindow> int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); QQmlApplicationEngine engine;

问题 A long time ago I remember using a program where I just moved my mouse around the screen and it displayed the hWnd information (and some other stuff) of the window (and parent, and child) to where you were pointing your mouse. Does anyone know of something like this? I cant find it anymore. (btw this is windows 7) Edited : it's not yet any of these, but Winspector seems to do what I want. I remember that it was done by a guy that was a master in window Subclassing in the VB5/6 days 回答1:

问题 I'm using a third-party class that spawns an instance of Internet Explorer. This class has a property, hWnd, that returns the hWnd of the process. Later on down the line, I may want to reuse the instance of the application if it still exists, so I need to tell my helper class to attach to it. Prior to doing that, I'd like to know if the given hWnd is still valid, otherwise I'll spawn another instance. How can I do this in C# & .NET 3.5? 回答1: If it is a window handle, you can call isWindow

问题 MSDN -> "GetDlgCtrlID function" -> Remarks: "... Although GetDlgCtrlID may return a value if hwndCtl is a handle to a top-level window, top-level windows cannot have identifiers and such a return value is never valid." It seems it is wrong information - "never valid". At least for Win2k...Win8 this return value is just kernel pointer to hmenu(bar). And my question is (primarily to MS insiders): why MSDN so inaccurate here? (Screenshot: http://files.rsdn.ru/42164/gwl(-1)_tagwnd.png) Upd
