问题 I'm working on a C/S application, Server in C++ and Client in C#, I need to send some information about current running processes and related icon. I get icon file thanks to EnumWindows with this code inside the callback... // Get the window icon HICON hIcon = (HICON)(::SendMessageW(hWnd, WM_GETICON, ICON_SMALL, 0)); if (hIcon == 0) { // Alternative method. Get from the window class hIcon = reinterpret_cast<HICON>(::GetClassLongPtrW(hWnd, GCLP_HICONSM)); } // Alternative: get the first icon

问题 I was having a look at the documentation for BM_GETCHECK and it seems that this functionality is only supported on Windows Vista and above. That is, this is not a supported message in Windows XP. A quick search online doesn't immediately yield an alternative way of getting the control state. Several other messages (this for example) that I would also expect to work on Windows XP are reported to not be supported. Does anyone have any insight into this? How does one generally handle Windows XP

问题 Is there a way to detect when a window that doesn't belong to my application is being dragged in windows using python/pywin32? I want to set it up so that when I drag a window whose title matches a pattern near the desktop edge, it snaps to the edge when the mouse is let go. I could write code to snap all windows with that title to the desktop whenever the mouse is released, but I want to only move the particular window that was being dragged. 回答1: So far the only possible solution I see is

问题 I'm trying to click somewhere on the desktop, I'm using python with win32 api, I'm using python 32 bit but my computer is a 64 bit computer. I believe the lParam variable isn't holding the value I'm expecting, and I'm still a bit confused about this variable itself, lets say I import it from wintypes can anyone tell me how to use it? Why does my function below not work? I have a function as following, this doesn't seem to work: def clickDesktop(x=0, y=0): # Get handle to desktop window

问题 TL;DR: Did GetWindowText win32 api change behavior on windows 10? I have some code that loops through all windows on the desktop to find a window where the title contains some text. When this code hits a window named "" with class "URL Moniker Notification Window" it hangs on GetWindowText. GetWindowText is trying to send a message, my guess is WM_GETTEXT. This window is part of the exe "SearchUI.exe", the process is suspended and can't process messages. When reading: https://blogs.msdn

问题 I want to be able to begin playing a song at a particular time (for example, 30 seconds into the song) in my program which replicates a radio station, where when you change the channel and the song is already playing or almost finished. Currently I use PlaySound and have my 26 songs saved as wav files and as resources within the program. I have seen mciSendString as an option however I do not understand how i could manage to get it to work when coding with Windows API and C++. Here is my

问题 I'm trying to get the name of processes which have a visible window. For example, if I have Chrome opened, I would like to get the string "chrome.exe", but I only get the init value "unknown" using the code below. I read around it could be an access rights problem, can you suggest me how to change them in order to get the name of processes? DWORD idProc = 0; //pointer to the process which created the window DWORD idThread = GetWindowThreadProcessId(Wnd->get_handle(), &idProc); Wnd->set_pid
