winapi

问题 I'm working with Python 3.7 on Windows 10. I would like to detect if there is any audio playing on my computer or not. I was looking into win32api.GetVolumeinformation but I'm unable to get what I want. When you control your audio you can see if there is a program playing and I want to achieve that. 来源： https://stackoverflow.com/questions/59636713/check-if-audio-playing-with-python-on-windows-10

问题 I'm working on a task for my game program, in which I want to hide my mouse after 10 seconds from my screen. However I'm able to check the mouse move condition... Here is my code.. using namespace std; HHOOK g_hMouseHook; LRESULT CALLBACK LowLevelMouseProc(int nCode, WPARAM wParam, LPARAM lParam) { if (nCode >= 0) { PMSLLHOOKSTRUCT pmll = (PMSLLHOOKSTRUCT) lParam; switch (wParam) { case WM_MOUSEMOVE: printf("Mouse has been moved\n"); break; } } return CallNextHookEx(g_hMouseHook, nCode,

问题 I'm new to attempting to write code in VBA to use WinAPI functions. What encoding does the WinAPI Normalize() function work with? UTF-16 is what I would expect, but the following does not work. The number of characters seems like it's not calculated right, and then the attempt to actually create a normalized string will just crash Access. 'normFormEnum 'not random numbers, but from ...

问题 I'm trying to call this native Windows method using JNA: HRESULT WINAPI DirectSoundCreate(LPGUID lpGuid, LPDIRECTSOUND* ppDS, LPUNKNOWN pUnkOuter ); But I'm really struggling with understanding what I should use as parameters on the Java side of things. With JNA you're supposed to create Java classes matching the native C structs, and I have done so succesfully with other parts of the WinAPI. From what I've (I think) understood so far the LPDIRECTSOUND is a typedef to a "Long pointer to a

问题 In Windows image files can be tagged. These tags can be viewed and edited by right clicking on a file, clicking over to the Details tab, then clicking on the Tags property value cell. I want to be able to read and write these tags using Python 3. This is not EXIF data so EXIF solutions won't work. I believe it's part of the Windows Property System, but I can't find a reference in Dev Center. I looked into win32com.propsys and couldn't see anything in there either. I wrote a program that does

When I coded my executable Microsoft was suggesting to use RtlGenRandom API to generate cryptographically strong random numbers. Now when I'm checking documentation for RtlGenRandom

问题 Is there a way to get all the API (Export) functions from a DLL file ? I know that programs such as Depend s and PE Explorer can do that but none of them retrieve the argument list. 回答1: Unless the exported functions are something like a COM DLL or C++ with munging, the information simply isn't there to provide the arguments. It's normally possible to find the total size of the arguments, and there's a pretty decent chance that dividing by 4 will give something close to the right number, but

问题 Why does the SetScrollInfo() function sends a WM_SIZE message to WndProc() ? EDIT Apparently, this is a bug in the WinAPI. The WM_SIZE message was being sent because I forgot to include the WS_HSCROLL | WS_VSCROLL styles in the window creation. Once that was corrected, the WM_SIZE isn't being sent anymore. Thanks. 回答1: Since this is a documented feature, it's likely not a bug. From http://msdn.microsoft.com/en-us/library/windows/desktop/ms632646.aspx: Remarks If the SetScrollPos or MoveWindow
