user32

问题 I need to use SendMessage fro simulating user clicks in a target program as SendMessage blocks until the event that it triggers is finished processing. The reason for this is that this blocking gives opportunity to detect if any dialogs have opened up as a result of the clicking. My problem currently is that although I can get the click to work using WM_LBUTTONDOWN and WM_LBUTTONUP messages consecutivly on a button in a mocked up form which opens a model dialog, I cannot get it to work on

问题 I received the following error on the first attempt of using the User32.Instance: Exception in thread "main" java.lang.NoSuchMethodError: com.sun.jna.Native.load(Ljava/lang/String;Ljava/lang/Class;Ljava/util/Map;)Lcom/sun/jna/Library; at com.sun.jna.platform.win32.User32.(User32.java:48) whilst trying to run a JNA pre-defined mapping of the Windows User32 class functions. I tried running the following code: HWND hwnd = User32.INSTANCE.FindWindow(null,"new 2 - Notepad++"); User32.INSTANCE

问题 My application uses multiple windows I want to hide one specific window in case the application loses focus (when the Active Window is not the application window) source I am handling the Deactivate event of my main form. private void MainForm_Deactivate(object sender, EventArgs e) { Console.WriteLine("deactivate"); if (GetActiveWindow() == this.Handle) { Console.WriteLine("isactive=true"); } else { Console.WriteLine("isactive=false"); } } [DllImport("user32.dll")] static extern IntPtr

问题 What is the Win32 equivalant of Form2.Show vbModeless, Form1 that allows me to set the owner (not the parent) to an arbitrary hWnd and set the default position, etc? As far as I'm aware, this can only be set when creating a window. 回答1: I'm not sure what you are trying to accomplish, but I think you might be looking for the SetParent function. Declare Function SetParent Lib "user32.dll" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long hWndChild is the handle to the child window.

问题 I am trying to retrieve information from extern desktop aplication in Windows. I know how extract the text from Textboxes (class "Edit") but I don't know how extract the values from controls with class name "ThunderRT6ListBox" and "ThunderRT6ComboBox". How can I do that? I have this code to extract the text from the textbox: public static class ModApi { [DllImport("user32.dll", EntryPoint = "FindWindowA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)] public static extern

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How to simulate Mouse Click in C#? I have tried Window = FindWindow(null, "untitled - Paint"); PostMessage(WindowToFind, WM_MOUSEMOVE, 0, location); PostMessage(WindowToFind, WM_LBUTTONDOWN, ((int)Keys.LButton), location); location is 100 * 0x10000 + 100 for 100x100 etc. I doubt its wrong. I have tried swapping ((int)Keys.LButton) with 0 , didn't work. I tried putting thread.sleep between lbuttondown and

问题 I'm currently getting into the ctypes module and I'm trying to call the user32 function GetWindowText with a HWND handle I already received by using FindWindow. This time though i wanted to process a step further and use a function prototype instead of calling the function with ctypes.windll.user32.GetWindowText . Although I´m having problems declaring the lpString arguement as output parameter. My first attempt looked this way: GetWindowText = cfunc("GetWindowTextA",windll.user32,c_int, (

问题 Am I doing this correctly? [DllImport("user32", CharSet = CharSet.Auto)] internal static extern long SystemParametersInfo(long uAction, int lpvParam, ref bool uParam, int fuWinIni); ... public static bool IsScreenReaderRunning() { long SPI_GETSCREENREADER = 70L; bool bScreenReader = false; long retVal; retVal = SystemParametersInfo(SPI_GETSCREENREADER, 0, ref bScreenReader, 0); //uint iParam = 0; //uint iUpdate = 0; //bool result = false; //bool bReturn = SystemParametersInfo(SPI

问题 If I don't use WM_SETICON first to set the icon then WM_GETICON is always returning 0. This is weird. Please help. This is my code, can copy paste into scratchpad and run. When doing SendMessage(targetWindow_handle, WM_GETICON , ICON_SMALL, ctypes.voidptr_t(0)) , hIconSmall_orig and hIconBig_orig is always returning 0 I have no idea why. IF you go WM_SETICON on the window first then it properly gets the HICON but the whole purpose is to get the default icon. Cu.import('resource://gre/modules
